Connecting a headphone to an Android via bluetooth

A rather simplified explanation of lossy and lossless conversion.
Images: BMP and PNG are all lossless image formats. JPEG and WebP are lossy image formats. JPEG/WebP discard quality to become smaller. How? say a background is all black lossy duplicates RAW Data over the entire pic once rather than a continuous representation of 9 zeros. Instead 8 are missing but are still represented by the digit 9. MP4, WMA are lossy conversions for film, usually used for the Web, creating a small compact file using the fore mentioned data loss, by replicating the background rather than leaving it RAW.
Audio conversion:
WAV, is a container file often used to contain lossless audio, although it is capable of containing lossy audio.
FLAC is lossless, MP3 is a lossy audio format.
Lossy audio files use the same premise as JPEG/WebP,MP4 WMA image conversion; 9 zeros can be compressed by discarding/throwing out 8,then using the digit 9 to represent all the zeros. Lossless files contain all 9 zeros and fit into the file size with out discarding/throwing out any of the zeros representing the RAW data.
Ex< a FLAC file only supports 24 bit audio conversion. A WAV 32 bit PCM audio file converted to FLAC would result in discard/throwing out some data.
ACC/MP3 like FLAC and MP4/WMA are lossy. No lossy Audio format is great according to my Audiophile roommate, I don't really hear a difference in quality between lossy and lossless other than decreased volume in the prior mention format. In Film it's clearly evident by poor quality in movement/pixilation.

I hope I haven't confused you more, LifeHack or howtoGeek.com have a plethora of info on this one format VS format/conversion.
As for your Bluetooth pairing/compatibility query. 4.0 needs to pair with 4.0 and so on. Follow manufactures pairing instruction. Ex; Its a myth that BEATS SOLO 3 wireless won't pair to Android devices and pair only to iPhone, simplifying it they discover one another because the "pairing Frequency" is the same, as in  4.0 to 4.0

As you had said yourself, the maps size can be known only when you start to download.  The app itself takes approx 20Mb (Total size = App size + data) and it includes no map (actually app will say installing World map, but unless you download a country's map you wouldn't be see anything on screen that resembles a map).

Map for France:

You might also be interested to download other stuffs other than map. For instance for UK, you can download postcode database which can be very useful for locating a destination without Internet connection. Also, it would be worth while to download speed cameras database so that you would get a warning when you approach one and warn if your current speed is high to cause you trouble.


Does android save a log of its own IP addresses?

If you have USB debugging turned on, you can see the DHCP activity in the logcat. Unfortunately, without a working DHCP server, you're not going to see anything.  And the logcat doesn't stick around long enough for you to see the previous day's successful negotiation. You can also see the currently-assigned IP address in Wi-Fi settings under the advanced menu. But again, this is only when everything is working right.

Without some inside knowledge about the subnet, you're reduced to guessing. Try 192.168.1.xx, 10.0.0.xx, 192.168.0.xx, etc. But you could also just check with one of your IT people.

If this happens often, I suggest checking your logcat or the settings menu when it's working and making note of the address. This will get you prepared for the next outage.


Use your browser to get onto Youtube.
Log in, using the account you want to have logged out.
Then use the 3 dot menu to sign out.
Now clear the data in your Youtube app.
(I also think that you can sign out with the settings in the Youtube app, but I can't say how as I don't use the app.)


Whatsapp Profile Pictures folder missing

WhatsApp no longer caches/stores the viewed profile pictures under /sdcard/WhatsApp/Profile Pictures/ directory, due many reasons, like this..Now, it's stored under its own app cache area in /data partition.

If you're rooted, then head over to the directory: /data/data/com.whatsapp/cache/Profile Pictures/.There, you'll find the cached profile pictures (that you have viewed).

If you're not rooted, as others have said, you need to explicitly save the profile picture from the WhatsApp app by clicking the pic, click again to enter full screen, click the 'Share' icon and press 'Save to Gallery'.

Now the saved profile picture can viewed in the directory: /sdcard/WhatsApp/Media/WhatsApp Profile Photos/

I can't hard reset or install any apps on my android device

There are some possible reason, You Can’t Install Apps on Your Android Phone

Your Android phone doesn’t have enough storage left

Open source app for remote wiping Android phone?

For non-rooted phones.
Up until 2.1 it is not possible. Regular apps do not have the permission to perform full wipes or factory restores. I believe there are apps that erase your call/sms records and your contacts.
Starting with 2.2, it seems Google is granting limited root powers to apps that use Device Administration. It is supposedly a way for enterprises to policy their employee's phones, and requires an extra confirmation by the owner. But I believe it could be used by anyone writing an app. In fact, the code for wiping seems so simple that I think you could write an open-source app yourself if you have some programming background. ;-)

For rooted phones.
There are remote wipe apps, but I don't believe any of them is open source (that I've heard of).
Remote Wipe for root users is possibly the simplest one, and it's in the market, but I've never tried it myself. This app is no longer on the market.


Battery - do they last longer if recharged when empty?

Modern phones use Li-ion and Li-poly batteries. So the battery life is  not affected by whether you charge them at 0% or 90%.
It only has a long term effect. Batteries degrade with every charge cycle. A cycle is usually a recharge from below 50%. So charging while the battery capacity is still relatively high has a long term effect of less degradation.

The other frequent pseudoscientific habit that has no roots is a technique many call "formatting", where you leave your battery plugged in for 16 hours or 3 * 8 hours with discharge in between or any other baseless claim by anyone on any forum or phone shop. If they don't have scientific evidence don't believe them.


Raise volume above recommended level? message

It's a European law which states you must be reminded every 20 hours of listening:

  The user can choose to override the limit so that the sound level can be increased up to maximum 100dB. If the user overrides the limit, warnings about the risks must be repeated every 20 hours of listening time.

Where does the Fastboot pull the information from?

the information comes from the misc partition.. /dev/block/platform/sdhci-tegra.3/by-name/misc

if you dd if=.... of=/sdcard/misc.img then do an adb pull /sdcard/misc.img you will see.. I stuffed up a root and had CDMA crap in there from one of the updates.. now no 3g either :)

but that's where it queries the information from.. doens't do an mdm_ctrl commands to extract it or anything.


Does Android USB Shared connection runs a DHCP Server?

Yes. Definitely.
What a DHCP server basically does is not only dynamically allocating IP addresses, but auto-configuring some IP settings as well, for example DNS servicing.
Judging from a client's (let's say, your computer) behavior, it surely runs a DHCP server. If not, you'll have to configure IP settings (static IP) and enter DNS server addresses and Gateway address manually. But you don't have to do these by yourself, so you can confidently infer that a DHCP server is working.


There are a few things which don't sound quite right.

4GB RAM - The Oppo R5 has 2GB RAM build in.
"eight core MT6592" - R5 uses an Snapdragon SOC. MT6592 is an Mediatek SOC.
The Android version. It doesn't matter which version is shown in the system information. It's a simple edit in /system/build.prop. Everyone can write whatever they want.

With these things in mind I think you have bought a fake R5.
So can you change to Cyanogenmod? No. By installing the cyanogenmod for the official R5 you might brick your device as the kernel is not fitting your hardware.

Restore power button to default behaviour

Just go full stock with a factory flash. See if the problem is present then. If it is, it is a hardware issue, and you can claim warranty. If it works, be a lot more careful with your apps next time.


Do a Google voice search with Belkin CarAudio Connect Bluetooth on a Sony Xperia

This can be done using tasker and the AutoVoice Addon. From the addon's description:

  Control your Android device with your voice, now even via your Bluetooth headset! You can even redirect all audio to your Bluetooth headset and also react to your Bluetooth headset button and do whatever action you want with it in Tasker.

Basically, you create a new profile in Tasker to activate AutoVoice (e.g. shaking the device, pressing the camera button, using a shortcut to the given task, whatever), which then acts on keywords even by regular expression match (there's also a "permanent listening mode" which you could enable on conditions like "power plugged in plus Bluetooth connected to car"). There are plenty of ways to realize different things with it, a full how-to would go much beyond the scope of this site :) You can even have AutoVoice triggering Google Now, if you like.

To go deeper into this topic, let me give you some links:

Lock Screen Dialer App Replaced with Microphone

I found the answer here:

  Go to Settings > Apps
  Click the Gear Icon (top-right of the UI)
  Click on Default Apps > Assist & Voice Input > Assist app.
  Click "None" (the other option is Google App).

  This puts the dialer shortcut back on the lock screen, but it also disables long-pressing the home button to launch the Google App.


Will JTAG wipe internal memory on Galaxy sII?

Your files even the deleted files Can be recovered even from dead phone with the help of JTAG or ISP Solutions !

1 - Find or Locate Pinouts

If your phone available pinouts for JTAG'ing you can JTAG otherwise you can relate to ISP pinouts if two option not available for your phone you can always chip-off and recover the DATA !

JTAG : ort-jtag.com
ISP  : emmc-pro.com

For the case of Galaxy S2 - You can JTAG or ISP Direct!

2 - Read the Full image of your phone !

After reading the full image of your phone with the software mentioned above .
You can analyze the Dump and extract your private pictures etc..

3 - Data Recovery
Data Recover : Autopsy ( Sleuth Kit )

Best Regards


When a processor speed is given for a multi-core processor, is that the cumulative speed or the speed of the individual cores?

Frequency is not cumulative. The chip runs at 1.8 GHz, each of the cores runs at 1.8 GHz, all four cores run at 1.8 GHz. If one car travels at 100 km/h and another car runs beside it at 100 km/h, you just have two cars running at 100 km/h, you don't have anything running at 200 km/h.

Instruction execution rate, on the other hand, is cumulative. If a single-core processor running f GHz can execute k instructions per second, then an n-core processor running at f GHz can execute n ⨉ k instructions per second*, just as our two cars together carry twice as many people as one car.

*In practice you won't see an n-fold increase in speed, as some resources are consumed in co-ordinating the cores.


Is it possible to retrieve app's local data after uninstalling it?

Answer 1

The usual practice for games backing up users' progress online is storing almost everything on the company's own private server, while storing a small "identity" file on device (much like Cookies in a browser), or use device's identifier / your Play Games identity directly. The company's employees (not all of them, but at least the development and support teams) have access to their storage.

Answer 2

Continuing Answer 1, there's no way for you to prove that you're the owner of the deleted profile, and the company don't want to get into trouble if you claim another player's profile. This is a bad practice because (probably) the game does not use device identifier.

Answer 3

As GiantTree has already pointed out in comments, you should check out this post.


Where does Android store the "default application for file type (open with)" settings?

On Jelly Bean, the preferred activities are stored in the XML file /data/system/users/0/package-restrictions.xml for the primary user. Other users have their user ID in place of 0 in that path. If encrypted file system is enabled, it starts with /data/secure/system instead of /data/system.

Other than through the PackageManager service, this file can only be accessed by root. You can see the code that reads and writes the file (and thus infer the format) in the class com.android.server.pm.Settings.


android cast for windows with 30fps using usb?

Try downloading this app called "AirDroid" from Play Store.

It has a feature called "AirMirror" which lets you mirror your phone screen over WiFi(root required) or USB(no root needed).

I've been using it for a few years and it's pretty stable.


Smart TV Stick (Android) connects to 3g dongle for Internet

You may get what you want, if you find a model that includes this functionality already (like e.g. the older Archos G9 tablets did) but it will not work out of the box for most models.

There's the autopatcher project (thread on XDA) that enables 3G dongles for modem-less tablets (but it is limited to certain custom ROMs like CyanogenMod, AOSP, rooted Google stock Android and others).

Regarding the power question: That's up to the exact model and you will need to find out by trial and error or get that info from searching Google/specs/etc. The same applies to your last question (but in general, those TV sticks are built to be plugged in and out and need to survive sudden power losses just as phones need to because they tend to run out of battery juice).


How can I restore the original ringtones and sounds?

If you are rooted, you can push this collection of media files to /system/media/

Without root, android should still locate the files if you place them in a folder on your SD card called "media" and retain the rest of the file structure from the zip.

Help me reinstall Gapps in my Rooted Xperia SP

First of all you don't tell us what exactly apps you uninstalled there is a chance that you uninstalled some app that cannot be replaced by just adding gapps. Varius gapps for all the versions can be found here https://goo.im/gapps/ please be carefull to choose the right version according to the version of Android installed on your smartphone.

You should not be afraid to flash .zips from the CWM, one of the reasons of root and installing a custom recovery it this one. Also it will save you a lot of time.

If the first line of this answer is true then you will have to reinstall the ROM that is currently being used at your smartphone.


How to block notifications in a certain period?

You have "Automatic rules" in Do not Disturb menu , there you can create an event/timerule named "work" give time period and occurrence of the event . Select the profile you want in this i would prefer priority only . If you still want some notifications you can increase priority of those notifications in app setting of that particular app .


Google drive making extra local copy on phone

Some possible causes to why the Drive app saves local copies:

The file has been accessed recently and cached. This is possibly to reduce more bandwidth usage when the file is accessed regularly. Clearing the cache from the in-app's Settings can save some space, including limiting the cache size to a minimum of 100 MB.
The file is marked as "available offline". Files that are marked as "available offline" will be automatically downloaded to the local disk. To toggle it, tap the overflow context menu (3 vertical dots) on the file, and select "Available offline". To check which files are marked as such, there's an "Offline" category on the navigation drawer.

No USB Storage Mode on GalaxyNexus running 4.2.2

Normally you would put the device into storage mode. When the phone is normally booted without storage mode you'll only be able to see internal, then when switched to storage mode you'll see the sdcard as well.

But VerizonWireless says the Galaxy Nexus doesn't come with USB storage mode. According to them you would transfer your data/files to PC across MTP.

So having the external SD card not show in PC explorer, can be bypassed by inserting it into a card reader on the PC. A little inconvenient, but will accomplish your task.


need to reinstall widget category on nexus 7

Many APPs have widgets that you can install on a panel of your home screen.  Long click on a panel of your home screen that still has sufficient empty space left for your widget(s) and then click on Widget then on the widget's app you want.   If there was no space left on the home screen panel you were on, you would not be able to see widget choices to be able to install a widget.

You wouldn't find Widgets on the App Screen unless it is an individual widget App.  There is a resemblance between apps screen and home screen, and that is what you probably remember.

You could have possibly answered your own question here, by clicking on the "Widgets" tab on your question, or better by clicking on tag at the top of the page and they typing "widget" into the tag search box,  or using the search box at the top of the page.


Share known WiFi networks between own devices

If you want to back up and restore though Google (Drive) then perhaps you  may need to look at some third-party applications such as
WiFi Password Manager or Wi-Fi password manager (whichever you prefer as there are more or less similar)

Basically the following features are present:

  Manage your wifi passwords (add, edit, delete)
  Backup your passwords to Google Drive or to local storage
  Wifi hotspots list sorted by wifi signal strength
  Recover wi-fi passwords from system settings (ROOT)
  Connect to WiFi hotspot directly from the appplication
  Copy password to clipboard
  Share wi-fi settings

Pretty straight forward to use simply add the target wi-fi network, then back it up on local or google drive, follow the reverse proceedure to restore:


Browser desktop mode not really the same as PC desktop

There are various ways of creating responsive webpages.

the developer can ask the browser to tell whether it is windows os or android or iPhone or which browser it is etc.

Secondly, most often responsive design is implemented based on the width available to the browser window. To learn more you can search the web or try for yourself as I explain below

In fireFox browser on PC go to menu -> Web Developer -> Toggle tools or press Ctrl + Shift + I

Now click on the button on left of three dots. You can change the size of page to see how it looks on browsers of different sizes.

Hope this helps.

Will I get automatically lifetime FREE updates if I pay for an app?

If the developer keeps releasing updates to the app as the same packagename and you already purchased the application previously, then should receive updates for the application for free.

E.g. if you went and purchased my app then you should get updates so long as I keep updating this specific packagename of the app: net.mandaria.cardashboardpro

However, I could at some point in the future decide that I want more money for the application and release a newer version of the application under a new packagename: net.mandaria.cardashboarddeluxe You would not get a free update to this app, even if it is technically the same application, I have chosen to release it as a separate app in the eyes of the Android Market (which determines two applications to be different solely by their package name).

However, I could still charge you for more money by including (optional?) in-app purchases or subscriptions that did not previously exist without changing the package name.  Carrying the same example, I could still use net.mandaria.cardashboardpro but have an in-app purchase for the "deluxe" features.

Most developers will not do these things to users who have already purchased their application, but it isn't impossible. Once such example of a developer trying to charge for a newer version of his application was psx4droid. The backlash was so vicious from his users that he went back and updated the older (version 1) of his app to the newer version (version 2).  He now has to maintain three versions because of this (version 1 and 2, plus a free version) instead of two.  Talk about a developer headache.

So ultimately it depends on what the developer decides to do.  In the majority of cases, the developer will keep supporting the same app and you receive the latest updates for free after your purchase.


Install google play games without internet connection

You can download a game and the use a similar application to get the install file (APK) and then move it using a micro sd card but most of the games on google play store require internet connection to download some content . I don't see any utility of doing this


Google has documented both the multi-user feature itself, and the associated API which shows what an application could do with it.

Behind the scenes, the multi-user feature relies on SELinux multi-level (MLS, aka. multi-categories) system where each user is associated to its own SELinux category (see NSA's presentation SELinux in Android Lollilop and Marshmallow for reference, in particular slides 13 and 14). This provides a very robust and reliable separation between users, enforced at Android's kernel level and therefore hardly bypassable.

In this scheme, there are public and private resources. Public resources are shared between all users, while private resources are the own private property of each user and cannot be accessed by others.

Public resources include mostly installed applications and global phone configuration. Note that you can restrict the way secondary users may use the device, for instance secondary users can be prevented from passing any phone call.
Private resources include mostly local user's settings, local application and user's data.

Now let's see what are the concrete consequences of these statements (I reuse your convention of user Foo as the primary user and user Bar as the secondary one).

  If I create a secondary user and install an app while using the phone
  as that user, will the permissions for that app carry over for the
  primary user?

Installed applications are considered as public resources, therefore if the user Bar installs an application then the same application will also be available for user Foo, even if the user Foo did never explicitly accepted the application's requested permissions.

However, user Bar will have no way to make the application run into Foo's profile, neither it will have access to Foo's private data. Moreover, except in the case of a badly buggy or downright malicious application (ie. an application which would copy private data into some shared location), both Foo and Bar can run the application, Foo and Bar's private data will remain safe (they can even use it at the same time if the application supports it, if it does not it will simply refuse to start or crash).

  For example, let's say I have a primary user, Foo, with a Google
  account foo@gmail.com. I then create the user Bar with the account
  bar@gmail.com. Whilst using the phone as Bar, I install an app with
  the "find accounts on the device" permission.

  Will this allow the app to see the accounts I have registered with the
  primary account, i.e. foo@gmail.com?

I just want to warn to not confuse the "Find accounts on the device" permission with the multi-user feature which is unrelated. Each user has its own list of accounts which is considered private information, and therefore not shared to any other device's users.

When Bar runs the application, only Bar's accounts will be available, whereas when Foo runs the application only Foo's accounts will be available.

  Will it even be able to find the primary user at all or are there hard
  boundaries between user "workspaces" (for lack of a better term), and
  as far as the app can see, there's only Bar and its registered
  accounts on the device?

The users list seems to be considered as public information, most likely as a Unix world historical inheritance since I do not see any technical reason for this. Personally I would have appreciated if it wasn't the case (ie. users more as transparent sandboxes than standard Unix users, at least as long as applications are not granted some specific permission).

Anyway, the Android API documentation page linked at the beginning of this post lists the methods that an application can use to gather information about current and other users. Most of them do not seem to require any specific permission.

  I'm just generally concerned with apps finding out about my personal
  data, contacts, emails, etc, and would like to use a "dummy" account
  for any app I consider hostile in this regard. Would this work?

Yes, I even think this can be a very good idea, just be sure to be in your dummy account when launching it since the same application may also be available for your primary user.

Usability notes:

The multi-user feature in Android systems still seems very young and not very mature. This means that there are impacting changes between Android version and compatibility issues.

For instance:

User types and authorization handling: how the primary user and/or a corporate central device administration platform may define or restrict secondary/restricted/profile/guest users rights in terms of functionality and applications they may use or install is subject to heavy changes between Android versions and underlying devices (while still running Android, tablets may offer different options than cellphones).
The same also applies to the way applications installation, permission requests, applications sharing and uninstallation are processed (they may be directly available, they may be displayed but marked "Not installed for this user", they may not be displayed at all while still leaving the APK available, etc.).
Some feature may come and go between the broken and fixed state between versions (the "Allow unknown sources" setting for secondary users has been reportedly unavailable for 5.0, fixed in 5.1, broken in 6.0, fixed again in 6.0.1).
Some applications may not work when using a secondary user (F-Droid for instance).

There are still what I consider to be missing features, for instance there is no proper way for a user to log out.


On the versions of the Play Store with the new "simplified" permissions dialog, you can still find a full list of permissions from the app's store page (the screen with the icon at the top, description, screenshots, &c.). Scroll down to the bottom of the page. Under "Additional Information" you'll see "Permissions" with a link "View details". Click this link to see a dialog with the list of individual permissions.

In particular, an SMS app might have permissions "edit your text messages", "receive text messages", "read your text messages", "send SMS messages", each one saying whether it applies to SMS, MMS, or both. They're pretty self-explanatory on the face of it, but there are some subtleties.

"Receive text messages" means the app will be notified (by Android) of a new message as soon as it arrives. This is normal for an SMS app, or for a few apps that use a special SMS to validate your phone number with some online service (such as Facebook).

In contrast, "read your text messages" lets an app get data from Android's database containing your message history. This means it can see messages sent from different apps, or messages you sent or received before you installed the new app. Any text message you can see in the stock SMS app, this app will also have access to. Again, this is normal in an SMS app.

"Edit your text messages" gives the app write access to that same database. For example, the app uses this to save messages or drafts to your message history. Again, this is completely normal for an SMS app. But it could also be used for an app that illicitly sends premium SMS messages to delete the records afterwards.

Like any permission, it comes down to trust. It's on you to decide if you trust the author of this app to only use these abilities the way you want: not just now, but in future versions of the app too until you you uninstall it.

As for why the S3's Phone app doesn't let you copy the number to the clipboard directly, or share it, only Samsung can tell us that.


No "Use system certificates" when trying to connect to WiFi

I solved this problem at my university (not Eduroam) by installing a CA certificate in Android (8). It then becomes a choice in the CA Certificate menu and you can sign in.

Hopefully, you can find out from the IT people where is the CA Certificate to download to your Android.

I think choosing "Don't validate" is unwise, and that's actually what many university IT web sites advise (Google finds the instructions easily).

Edit: for Eduroam, there's an app that reportedly solves the problem for Android 8.


How to have my phone guide me through a specific route

The solution I use for similar situation is Trekbuddy.  I am sure you will discard the idea of using this app if you didn't understand it well. Hence, read through its description in its Play site and their forums. It requires little homework before any such serious use. But once you know your way (pun intended  ) through the application, it will be a breeze.

With this app, you can plan your route on computer export it as GPX and together with few MP3 files you can create a turn-by-turn pre-planned navigation.  Be aware that if you miss your turn this will not reroute you back. You have to see the map that and continue either on the new route or try to join the pre planned route.

To know about its other uses, take a look at my answer for the question "How to import GPS coordinates track for using offline"

You may also try OSMAND. You can create a pre planned route and export as GPX file. OSMAnd can be configured to use this pre defined route. I could not get my head through the options and configurations to make this work. But from reading its help, I understand that this can do the above and even reroute in case if you miss your turn.

Personally, I like Trekbuddy for its simplicity and its many features as I described in my answer to the other question.

If you happen to succeed with OSMAnd, please share your procedure with us.

Update:
After reading through the forum pages of Trekbuddy,  I finally figured out how to use a pre planned turn by turn navigation feature and I tried today to ensure it is working.

The steps involved are (from scratch):

Install Trekbuddy either from PlayStore or from their download link.
Run the app with GPS switched on. Press Menu and press Start and wait for GPS fix. If GPS fix is a success you will see the cross hair at your location in the World map.
To display a map, you have to download raster map tiles from the service provider.  These tiles are to be placed in a particular format and an application called Mobac comes for rescue. This app creates such map tiles, indexes and even compress. Various map sources like OpenStreetMap, OpenCycleMap, Google Maps*, Google Terrain*, Google Earth Satellite*, Yahoo Maps etc can be used. Explaining how to create a map will be bit out of scope here, and I will leave it to a rare tutorial available here in German.
Assuming you had successfully created a TARred atlas (collection of map tiles as said above), you have to place the .TAR file and its subfolder inside \mnt\sdcard\Trekbuddy\maps folder. To load the map, press Menu button and touch Maps option and select the *.Tar file. Depending on how you had layered the atlas, layers might appear in the next screen and if so, select a layer. Trekbuddy might prompt you to mark this as default atlas. If acceptable click Yes and you will save all this step doing again.
One map is loaded, you can ensure it by tapping any where in the screen, which will show the cross hair on your location in the map as identified by the GPS.
In your computer plan a route and mark turning points as waypoints. As an example, in this following image
 six waypoints are marked as WPT1..WPT6.
In computer, using a text editor, create a GPX file with following template.

Place the GPX file created as above in \mnt\sdcard\Trekbuddy\wpts folder.
Place sound files in AMR format (MP3 not tested) in \mnt\sdcard\Trekbuddy\sounds folder. The file name of these files should be as mentioned in the GPX file.
And finally, in Trekbuddy app, press Menu, Navigation, Waypoints and choose the above GPX file. Then choose the final waypoint, in this case WPT6 and press menu again and choose NavigateTo.

When you start moving approach WPT1, the sound assigned to WPT1 will be played. The setting Settings->Navigation->Wpt Proximity determines the proximity radius. The value is in meters and when the current GPS position is within this imaginary circle, the sound will be played.

  I believe it has been discontinued since Mobac version 1.9 onward due to legal pressure. Old versions are not officially available but are still at large.


This seems to be a known problem when using
[ROM][5.1.1][SM-G360H/HU] CyanogenMod 12.1 for Samsung Galaxy Core Prime
The original developer >>doesntexits<< already knew this and provided a flashable zip file which seems to fix problems related to bluetooth.

This flashable zip file has to be downloaded and installed through the recovery.

ABNT2 keyboard for Android x86 2.2 r2 sparta "distro"

I would suggest looking at alternative input methods (keyboard apps) that specifically support Portuguese language.

I personally used AnySoftKeyboard, which does have a Portuguese language pack.  There are many other similar keyboard apps on the Market as well.  You might need to get them elsewhere though, since your build most likely doesn't have the Android Market access.


Is there an advantage to powering-off the device "properly"?

Shutting down an Android device isn't that much different than shutting down a computer — it gives any apps that want it notice the device is being shut down (allowing them to save data, cleanly shutdown network connections, etc.), shuts down networking (e.g., chance to release a DHCP lease) gives the radios a chance to shut down (e.g., to sign off from the cell network & WiFi network), and cleanly unmounts all the filesystems.

Everyone knows, however, that phones aren't always cleanly shut down. Batteries die, users do things like rip out the batteries, etc. So the software is all designed to recover from this — though it's surely less-tested than the orderly shutdown. (Desktop and laptop computer software makes quite a few more assumptions about not having the plug pulled, hence the greater damage there.)

Almost certainly, it'll take longer for various things to realize your phone has gone offline. For example, a chat app may still show you as online for a while after you pull the battery, but on a clean shutdown you'd show as offline immediately. (Or, similarly, it may take a wile for another device to take over). Not sure how much the cell network cares, but maybe it'd take a little bit longer for a call soon after battery pull to forward or go to voicemail.

Recently-changed data might be lost or rendered inconsistent. What that means depends on the apps involved. E.g., for an email app, if you pull the battery immediately after sending an email, maybe it won't actually be sent. Or maybe it will be but will be missing from your Sent folder. Or maybe it'll be sent but the "it was sent" data didn't get saved, so it'll be sent a second time after booting.

There's probably a tiny bit of additional wear on power components & very tiny bit on battery connectors, but I doubt that matters unless you're doing this tens or hundreds of times per day.

But yeah, if your phone had been basically idle for a bit, and then you pull the battery, probably no real bad effects.

After an unclean shutdown, various filesystem & database journals will need replaying, so boot is probably a bit slower. Only a stopwatch & some experimentation could say how much.

PS: When the battery is low, the phone is supposed to do a clean shutdown, not just drop power. Sounds like your battery is at the end of its useful life and has built up an unacceptable amount of internal resistance causing voltage drop when high current is suddenly needed.


How may I submit a WiFi hotspot to Android's database for a better triangulation?

TL;DR version: Just use the GPS.

Long version: Turn on Wifi positioning ("Location & Security > Use wireless network"), turn on GPS ("Location & Security > Use wireless network"), use Google Maps (or other GPS applications), then walk/drive around your city.

When you turn on both of these services, before the GPS acquires a "fix", Android will send the Wifi's MAC/SSID and Cell Tower base stations CID/LAC around you to Google's server and Google's server will send back your location information; after the GPS acquires a "fix", your device will send the Wifi MAC/SSID, Cell Tower CID/LAC, and your GPS location to Google's server and Google's server will collect this information to refine their own Wifi database.

note: I believe the device could also be sending other data, like signal strength and possibly ping latency; but I'm not sure about the specifics of these.

Also from Google's support forum:

  by Christopher (Google Employee)

  If your location is being incorrectly
  detected by a Google Maps or Latitude
  using Google's cell ID (cell tower) or
  WiFi (wireless network) location
  database, you can help provide updated
  info to correct Google's database
  using Google Maps for mobile. At this
  time, you cannot provide individual
  updates to Google's location
  databases, though they are being
  updated and improved constantly over
  time.

  Open Google Maps on an Android
  2.0+, Windows Mobile, or Symbian S60 phone and enable GPS. While Maps is
  simultaneously connected to a GPS
  satellite and a cell tower or WiFi
  router, you will be providing updated
  anonymous geographic data for the cell
  tower or WiFi router to which you're
  connected. Please note that this data
  is anonymous and may require a
  significant amount of data from you
  and other users before changes are
  made to Google's location database.

  Android: You must enable Settings >

  consent for anonymous location data
  collection. You can check if you've
  given consent by un-checking and
  re-checking the 'Use wireless

Will I get back my IAPs after reinstaling a purchased app from the Google Play?

Yes. Your in-app purchases are saved on your Google account. When you re-install an app it should restore the purchases given that you are logged in with the account you used to purchase.

Sometimes the app doesn't restore the purchases. In this case you should find a button in an app saying something like Restore In-App Purchases and click it. You should have everything you purchased.

If you still don't have your purchases restored you should contact the developer. Since your purchases are stored on your Google account they can verify that you paid and restore your purchases manually.


Does freezing apps in Titanium Backup Pro require a phone reboot to take effect?

You shouldn't need to restart after freezing an app. Once you freeze the app, it should disappear from the apps drawer.


Notes:

Rooting allows you to install a custom recovery (Clockwork Mod or AmonRa) to install ROMs
S-OFF allows you to change the HBOOT to rearrange your internal partitions

I rooted with Unrevoked before I used Alpharev's S-OFF some months later

Nowadays it's easier apparently. You can get S-OFF with Unrevoked Forever too but I'm not sure your phone is supported. And Unrevoked/Alpharev teamed up for revolutionary

Finally, there are many ROMS out there, some are better then others. I use Oxygen personally with the Oxygen HBOOT for 330MB internal data space. I'd use Devnull (same developers) but it doesn't have long press to kill


OK, so it's quite obvious that your phone is receiving 3G service (likely EDGE/UMTS), not just the 2G GPRS service.  GPRS is simply not capable of the speeds you're getting.  Since you've called the carrier and had them check, it's their problem.  I would say just go with it and enjoy the free service.  Don't let them charge you for it if they figure it out later, since you did try to make them aware.  If you're worried about it just call again and make the situation really clear.


Realtime Transfer (Stream) the Audio to "another mobile" device "directly" without any in-between components?

There are many apps in the market which you may use to achieve this;

StreamFurious
ServeStream

Both app require you to posses access to a ShoutCast server. (which is a server technology to host what you broadcast. learn more). Services like listen2myradio provides such services for free. This will allow anyone in the world to listen what you play, realtime!

You may also use bluetooth (with apps like Bluetooth Music Player) or wifi (with apps like WiFi Audio Wireless Speaker or WiFi Speaker) if you want to stay at a limited area.


Is there anyway to save my contacts and texts on a Samsung Galaxy Nexus with broken screen?

I'm missing some information:

Is your phone rooted?
Do you have USB debugging enabled?
Are your contacts synced to your Google account?

Since it isn't clear from the question - have you checked that your contacts aren't already backed up to your Google account? If you had your contacts synced - then they should all be backed up to the cloud / your connected Google account.

If that's not the case, and all you need is to be able to see your screen and control your phone (via the app of your choice) - you can try this kind of solution - an an MHL-enabled USB port.

Also, maybe Airdroid, can help as well.


Here's what needs to be done:

Launch Settings app → go to Sound & notification → tap Other sounds and slide leftwards the switch for Vibrate on touch to disable the latter.

Possible to connect Android phone to a port on router

Sorry I violated the forum's strict posting rules....
I found answers to both my questions on a couple of other forums - so, sharing KNOWLEDGE
 1. both my son's WIKO and my SONY XPERIA XZ have reportedly had the driver removed or incapacitated in the Linux kernel and as neither phone is ROOTed there's no way strightforward way to install a driver
 2. and yes Robert, I meant the RJ45 Ethernet port


This feature is not inplemented and has a low priority: https://trac.videolan.org/vlc/ticket/7072

There are many alternative tools in the play store that offer this feature.


The Notification Bar uses the global date format. So, just switch to the desired format from Settings ~> Date and time ~> Select Date Format.

For the lock screen, use a lock screen app. Search the Play Store, you can find many.


Replacement SD card not mounted properly in device

Okay, I figured it out (hat tip to @IrfanLatif). What's going on is this:
Android focuses on one single "primary" SD card that can be used to permanently enhance internal storage, e.g. by moving apps to it.
When it is removed, the system remembers that apps and settings are still stored there, and waits that it shows up again. Other SD cards can be formatted for internal use, but they won't actually be usable until all ties with the known SD card are broken.
This means the card must be explicitly forgotten. The option to Forget a card is available from the Storage menu when that card is not currently inserted.

Be sure to backup everything you need before doing that.
Eject the card via the menu and remove it from the slot.
Tap the card's name in the storage menu and then "Forget".
Confirm the warning that all data on that card will be lost forever, since the card is encrypted and Android is about to delete the encryption keys.

Only after that, Android will accept a different SD card as its primary storage and make it available to the rest of the system.


How to check if GPS is working (Android 2.1, Samsung Galaxy-5)?

Indeed, there is - the aptly named GPS Test app ought to help you.

The more popular GPS Status & Toolbox is also similar and will display your current lat/long co-ordinates and also a compass. Both are currently freeware.


How to update Google Play Services without having a Google account?

You will need to goto a 3rd party website that hosts Google apps and download the newest (for your device) version. The one I use is  http://gappsandroid.blogspot.com/ , you can download EVERY single Official Google app.


What's the safe limit on charger output for a Galaxy Nexus

All phone (wall-type) chargers are voltage sources, i.e. the adapter provides a stable voltage output (5V here) and the device decides how much current to draw. Your charger's specification says it provides a maximum of 2Amps. That means it will sustain its 5V output voltage up to a current of 2A.

The phone's internal charging chip may or may not charge the battery in a voltage or current driven means (Li-Ion are typically charged voltage driven and current capped if I'm not mistaken). However this is completely hidden internally and you don't have to worry about it.

If the adapter can't handle your phones current need, it may get hot or the phone may just discharge (instead of charge).

It may even be the case that your device draws less than it would need to charge (if you do navigation for example): What causes battery to drain faster than it can charge?


Download multimedia message with WiFi calling enabled

OK. So I called up Sprint. They told me that having WiFi calling enabled doesn't allow for MMS download because it makes the phone use all its bandwidth from the WiFi for calling, none for those messages.

So theoretically if you have WiFi but not WiFi calling enabled you should get the messages.


As both phones are identical (make that sure first!), there's even a possibility to "cross-clone" them:

First you'll need a custom recovery such as clockworkmod or twrp. Other than "stock recoveries", custom recoveries support...
nandroid backup: Using your new custom recovery, you can create a Nandroid backup of each device – which basically is a collection of "drive images" from all the partitions the device has. They will be stored on your SDCard usually.
Now swap the SDCards, enter the custom recovery again, and restore the Nandroid backup. With this step, the "body switch" should be perfect :)


What should I store on my external SD card?

As long as it's a good quality, fast card (class 4, 6, or 10), you can store everything on it from your apps to music, pictures, and video files, and even record HD video and take high MP pictures directly on to it. You should notice a significant increase in read/write speeds depending on the class of the card.

Download location of pdf files saved in the of Academia app

Android usage Linux based kernel and security, so every app runs in its own sandbox. Although storing app specific files depends on the developer most of them store in app specific folders which again can either be accessible by user or not. If you can't find any app specific folder created on your sdCard(external storage) look for /Android/data/yourAppSpecificPackageFolder [in your case /Android/data/com.academia.academia] in internal storage, you can look for folders within this. It can be stored as it is(.pdf) or some other format which default applications might not understand(so you can't open it).
If you don't find here then it might be in  /data/data/yourAppSpecificPackageFolder for which you need to have rooted device.


No arrow keys on Swype keyboard after updating to 4.4.2

The arrow keys I had now don't exist.

It's probably because the update also updated the keyboard app which no longer now has arrow keys implemented. There is a way though, you can always use third-party keyboard apps from Play Store. Many do have arrow keys: Hacker's Keyboard is an example, and SwiftKey is another example.

  Also, when it gets a word wrong, I cannot back-delete characters, it
  just deletes the entire word.

This is because of autocorrect. You can disable it in keyboard settings by going to Settings -> Language and Input and check your keyboard's settings.


Bluetooth keyboard won't re-pair to my Galaxy Note 10.1

YouTube app holds a long wakelock. What app settings can I change to keep it from doing this?

You can use Wakelock Detector in combination with Greenify to block wakelocks and save a lot of battery.

Update: Since Gingerbread is not supported by Greenify, you can use Wakelock Terminator to stop the wakelocks if you have root.


help I need to root my android due to "no memory space" but dont want to loose anything

Rooting your android device is completely safe as long as you follow the instructions correctly. Rooting won't free up internal memory by itself. It does enable you to remove any unwanted system level apps. You could then use applications like link2sd to free up additional space. Do a quick search about how to root your device model at xda-developers.com. Hope this helps.


How to improve camera shooting responsiveness?

How can I see the status of the latest CyanogenGen builds?

Rule of CM - never ask for ETA's, changelogs!

Only recourse is to look up the review site instead and filter it out for the appropriate device instead to see what code changes were checked in/rejected, in this case, use this as a search query on the top right hand corner of the page.

status:open project:CyanogenMod/android_device_samsung_galaxysmtd

Then can drill down the review, depending on what type of CyanogenMod ROM, be it GB, ICS or JB.

Usually, there is a reason as to why there's no build, check with their forum or IRC channel. :)


What happens if you install another phone's kernel on yours?

At a simple level, the effects would be catastrophic. The system wouldn't boot, and you would probably hard-brick OR super-brick. Kernels are the direct system for managing communication between software and hardware, among other things, and the kernel needs to be just right. If the device hard-bricks, a USB jig would need to be used to force the device into a usable state, or just get a new phone. Super-bricks (which are usually Nexus-only, since even a Nexus can recover from a hard-brick easily) will require a new phone completely, whether you like it or not.

Luckily, it's a Nexus. It takes A LOT to break them. It will definitely soft-brick (the primary OS is unusable, and the rest is fine) and probably hard-brick (not too likely), and a very low chance to super-brick.

To sum it up..

No, kernels DO NOT work on other devices
You would be really, really, really lucky to have a usable device. By that, I mean that you would have to be lucky enough to get into recovery or fastboot and install a stock kernel. Then, plain sailing.


Did you enable the developer options again after doing a factory reset?If not follow the below steps to enable it.

Go to Settings, About phone and tap on build number 7 times to unlock/enable Developer options again (factory reset would've put it back to the default of locked/disabled).

Enable USB debugging from the developer options after the above step for adb/fastboot to work.

No Internet through Messenger/Whatsapp/Viber apps

This could have happened if you're using a WiFi  network which uses a proxy server. The browser works just fine in this case but the other apps like WhatsApp or Messenger are blocked through the settings of the proxy server. TRY running these applications using your own mobile data or a WiFi network which do not have proxy.

updater-script—Universal Method of Mounting partitions

As long as the recovery has busybox (e.g. TWRP for most if not all devices) you could simply call run_program("/sbin/busybox", "mount", "/system");. I wrote my own updater-script and this worked fairly well since the Android 5.x days.


What might be the cause of the weird colors and picture mis-alignment?

Have you tried different resolutions on the Android video source and changing the refresh rate between 50 Hz and 60 Hz. My cheapie tablet offers:
1920 x 1080p 50 Hz
1920 x 1080p 60 Hz
1280 x 720p 50 Hz
1280 x 720p 60 Hz
720 x 576p 50 Hz
720 x 576p 60 Hz
All choices under Settings-->HDMI-->HDMI Resolution.
My guess is that you are sending a higher resolution than the target can handle.


SMS and MMS are general, system wide messages available through the Android API. Messages by any third-party app are independent from that and cannot be retrieved without reading the original database files containing those messages. (Which basically means it involves a rooted device/root permissions)
If you force close an app it is shut down and doesn't run. It does not remove any permissions what also means that another app may launch that app and that app may read your messages then.

Apps that don't run are not doing anything but the permissions persist. Using an application that is able to manage those permissions can revoke those permissions permanently.

How to remove Google Account that is set for Android Market in device?

You can't currently remove the primary Google account that you used to set up your Android device, the quickest way to switch to your new Google account would be to restore factory defaults and set up your device to use the new account.

The location of the factory reset depends on the Android version of the device. On ICS (4.0+) devices it's in Settings -> Backup & reset -> Factory data reset. On Honeycomb (3.x) devices it's in Settings -> Privacy -> Factory data reset. The same goes for Froyo + Gingerbread (2.0-2.3.x) if i remember correctly.

Note that this will clear your apps and their data, and depending on your device, MAY wipe your internal and/or external SD card, as TryTryAgain mentioned.


How do I reboot Samsung Galaxy S when it locks up? Is pulling battery bad?

Android is pretty resistant to faults resulting from sudden power loss, but there's always a risk of data corruption/loss, depending on open apps and files at the moment.

Have you tried holding the power button longer, for about 15 seconds (until the screen goes black and the normal startup screen appears)? On my Galaxy S this triggers a hard reboot, meaning that the phone forces itself to restart without regard to the usual shutdown process. I'd think it's a bit friendlier than pulling the battery, but nevertheless, it's a "wrong" way to reboot.


Searching the Market for "Midi" shows quite a few apps that have some level of midi functionality.   If you're looking for a full-fledged midi app such as you'd find on a PC or Mac, you will probably be disappointed due to the small screen and limited hardware interfacing capability of most Android devices, but if you are looking to experiment with midi functionality, one or more of these apps should do the job.

How does wpa_supplicant differ from the Linux (say Debian) version

In Android, wpa_supplicant deamon, wpa_cli and libwpa_client library are generated from wpa_supplicant external project found in aosp_root/external/wpa_supplicant; being in the "external" folder means that it was taken as is from another project (means wasn't Androidized in any way). so I think there are no differeneces at all.

Also the README file found in the project says that it can work on all distros based on linux kernel.


How can I enable/add USB OTG support to my rooted stock LG P500?

In short, MSM7x27 chipsets have very limited support for USB OTG, that is despite there is an option in the kernel to build the driver for it, unfortunately it does not work and requires hackery to get it to work 100%!

In reference to this:

  Update: My phone's has three files libra.ko, librasdioif.ko,
  wireless.ko in /system/lib/modules

Those modules the OP referred to, are tied to the SDIO's chipset support for both the SDCard mechanism and the Wireless. Notably, Atheros's ar6000 uses the SDIO pins to activate the wireless, and is specific to that driver.

Offtopic: The SDIO controls the SDCard mechanism, so yeah, it does sound 'cheap' in the sense that using the pins for I/O off the SDCard mechanism, to control the wifi chip...

As a FYI - Zte Blade and LG-P500 uses the near-identical array of peripherals such as chipset, wifi, but under different manufacturers! Have a mooch around the Modaco thread governing both devices, you might find something in there!

Force specific folder to be added to Photos?

Delete the .nomedia file to force media scanning  (
restart the phone. It is then that media scanner database is re indexed )
and it should appear in Google photos folder list for sync.
If you don't want that folder to be scanned by media folder at all, create a new folder in gallery ( use a third party file explorer from Play store , if your built in explorer can't do this ) and copy those photos into this folder manually. Verify, it's showing up in Gallery options to sync
Obviously, you wouldn't want to manually do this every time you use that app, so automate it. Macrodroid app implement it this way

Trigger: Application Launched / Closed → Closed → Select your app

Action:  File operation → Select   paths and move / copy options

This ensures that everytime you close your app, pictures are moved / copied into gallery sub folder and available for sync


Google Play allows publishers to respond to users' comments?

Yes, developers can reply to a user review. The user will get a notification via email.

GSM only this will use only 2g


How to use GPRS (not wifi or 3G) to get internet access?

This sounds like something that you need to make sure your operator has enabled on your contract, normally with smartphones a data plan is a data plan, once you've got one they give you a (monthly/weekly/daily) bandwidth limit which you can use either on 3G or GPRS, the operator doesn't care which you use.

It sounds like you don't want to pay for a monthly data limit, you want to get a metered contract where you only pay for when you use it (normally charged by the megabyte or by the hour, or something similar).

You can then turn the data connection on or off depending when you want to use it. The exact setting for this can vary from phone to phone, but is normally under something like Settings -> Wireless and Network -> Mobile networks -> Use packet data. On many phones you can also switch to only use GPRS or 3G (sometimes called GSM and WCDMA modes) but all that does is control the speed of your connection, not normally how you're charged.


How can I change the default browser on MIUI 10.x?

In your Settings application, navigate to System Applications Browser.
You get a prompt saying:

  Set as default browser?

  MIUI Browser is really great blah blah blah
  blah blah blah blah blah blah.

  No Thanks | Set

Tap "No Thanks".
Make sure "Set as default browser" is in the off position (grayed dot, not blue dot).
Open some application with web links.
Click a web link.
You will now get the dialog for choosing the app with which to open the link.
Tap "Remember my choice" or some equivalent wording before choosing your new default browser.


When I'm trying to run "xterm" in termux, it says failed to open display : :0. Why so?

It seems there is some kind of firewall,which is blocking the connection. I was unable to solve this problem. But I found a work around.
1. Entered a terminal with root privilage.
(E.g : used command su in a terminal emulator)
2. Created a 2nd loop back network by ifconfig
(E.g : ifconfig lo:0 127.0.0.2 netmask 255.0.0.0 up)
3. Fortunately "XSERVER XSDL" recognized this new network without any complain(Never thought it could detect such a weird network).
4. At last set my display to new server from my chroot environment as shown in XSERVER welcome screen.
export DISPLAY=127.0.0.2:1
startfluxbox ( or any xclient program, now everything runs fine)

Note 1: Each time my phone is restarted, I've to create the loopback network again. There might be some .rc files for adding startup scripts on android too. But I never bothered changing them(because I don't restart my phone often).
Note 2: I would really appreciate a true solution though(better if it works without root) because my method can't be applied on a non-rooted phone. So people with this problem but without a rooted phone can't use xserver untill someone finds another solution.


Need help in unbricking soft bricked LG G2 LS980

Flash with custom ROM.

Important:

Backup IMEI and WiFi MAC address before flashing (nvram folder).
Use a laptop with fully charged battery, same for device.
You may need try different ROMs, don't worry if the first one did not work.


How do I stop Archos Video Player treating some television shows as movies?

After further digging, it turns out that if the video file has the ©nam atom populated, Archos Video Player will consider the file to be a movie and use that value to search TMDb.

In the example I provided, the video file had the value A Surprise which was the name of the episode. Since the app incorrectly treated it as a movie, it performed a search for A Surprise on TMDb and the first result was Dreamship Surprise - Period 1.

To add further confusion, if there are no results from TMDb then Archos Video Player resorts to (correctly) treating it as a TV show. As a result, it can look quite random as to whether or not a video file is considered a TV show or not!

Should you need to force Archos Video Player to treat certain video files as a TV show, then you need to remove this value.

To do this:

On Windows, right click on the file, select Properties then the Details tab and ensure that the field called Title is empty
On Linux, install AtomicParsley and run AtomicParsley filename.m4v --title "" --overWrite

Once you've done this, the video file will now be correctly treated as a
TV show.


Is it possible to change password on the phone itself for gmail/market/other google apps?

Not a perfect solution but you can change your password by opening you Google account/Gmail on your phone browser.


Remote Battery management service while SureFox Kiosk is running

Lost password on Galaxy S2, can't shut down

To force the Galaxy Tab E to restart, hold the power and volume down keys for around 20 seconds. This has the same effect as physically removing the battery. If this does not work, attempt holding all four physical buttons for 20 seconds. After the device is turned off, start it up in the recovery mode by holding volume up + home + power. Highlight Wipe data/factory reset with the volume keys and select it using the power button. Select Yes and the tablet will be restored to factory specifications. Finally, select Reboot system now to restart the device.
During the setup process, Factory Reset Protection may kick in. Log in to the Google Account previously used on the device to disable it.


Voltage is not a good indicator normally of State of Charge (SoC) for Li Ion batteries, since the battery can show higher Voltage but not hold charge. Graph 2 highlights the relatively flat Voltage curve, compared to SoC drop
Voltage of a fully charged battery should be 4.2V (see table 2).

Seeing your comment on battery voltage being less, after 2 days of charging (less than 3V), surely you have a problem, since the Battery is considered "dead" at these levels

Possible fixes

I would suggest you to borrow a battery and see if it works fine. If it does, the solution is obvious- of changing the battery. If it doesn't help, it points to a  possible hardware issue in the charging circuitry, best rectified by qualified folks
Since the problem occurred after an update, it is possible that battery charging related drivers were not properly installed/ corrupted. This can be checked by reverting to earlier build or re flashing the update , which is difficult given that you can't power on your device, and would again need service center help

I am more inclined to believe that  it's on account of botched updation, since Li Ion batteries don't "suddenly" die


How do I automatically add all existing apps to my home screen?

Android launcher(s) is a dedicated app that serves as an UI to the underlying OS. There are tons of launchers available with features catering to the tastes of needs of users. If one needs features to be added to the existing (OEM or third party), they cannot be provided by yet another app because the launcher is so closely tied with the Android OS. Either the developer of the launcher, provides the requested feature or one uses a different launcher with that feature.

Case in point is the requirement of OP to add all installed apps with the OEM Moto launcher (instead of having
 installed apps in the app drawer). OP is looking for the functionality of ABC launcher to be added to Moto launcher. This isn't possible for reasons explained.

Android users, usually, let pre and subsequently installed apps be in the app drawer and choose the apps, they access more frequently on home screen, organized in the manner of their choice. Launchers let you search for  apps, even when they are not on home screen. In the app drawer, they may be sorted alphabetically, or organized by functions (e.g.games) or user created panes (e.g. shopping /banking apps) etc. The possibilities are endless and there are launchers available for different needs. Nova launcher is famous for exactly this - letting the user customize practically each element of the launcher interface (the reason I use it)

tl:dr; You choose the launcher that works best for you


Storage and Deleting Apps. How. What is Syncing and is it necessary?

I have a Sony Xperia and i can't delete apps or move then to my sd
  card cz I keep getting warnings about my internal storage.

Can you show me the message? About moving app to SD card, if the device is running 4.4 then there are chances the OS won't allow you to install apps on external SD card. I'm not using any Xperia model so I'm skeptical. A device model could help.

  How do i delete empty and unwanted apps and how do i store apps and
  other daya to my sd card.

Did you mean apps or folders? I suggest uninstall apps from Settings -> Apps and select from the Downloaded list there. If you meant the folders then you can delete them using the Files application.

  Iv lost all my photos and videos from factory resetting and not backing up my data.

Always pull out things first before factory resetting. And be warned that synchronizing may not back up all your data. Video, images and apps maybe left out unless you use some other specific apps for that.

  Also id it necessary to sync everything. What does syncing do.

Normally the sync will be managed through accounts. You can go to Settings -> Accounts section and select one of the accounts here. Tap on it and see the checked options. Checked means synced, unchecked means not synced. Simple as that.


What I wanted doesn't seem to be possible. It makes sense, really, as if it were possible it would represent a major security hole that would allow any app to gain root.

I ended up wiping my phone and testing the quality of my backups. (They weren't as good as I'd hoped.)


This was my mistake. I had the proxy server configured incorrectly. Packet forwarding was not turned on so no traffic other than the intercepted port 80 and 443 traffic could reach the internet. Since Google uses ports in the 5000s to determine connectivity and those ports were essentially blocked no internet connectivity could be determined.


Wiped data, cache and everything on Sony Xperia Neo V MT11i, now it's stuck at Sony Logo!

First thing is to make sure your phone is charged fully, or at least above 80%.

Also make sure you're connection to the PC is undamaged, USB ports in good condition, USB cable too.

Make sure you have the correct drivers for your device and the all the correct information about the device to prevent installing another incorrect rom.

If you get the adb to work using those tips, clear the cache and data etc. On the phone to remove any chance of the correct rom being corrupt by the one you tried to install before. (Don't forget gApps!!)


How do I open a Photo attached to a text Message?

Try this:

On the messaging app, (without opening any thread), tap on the menu key and go to Settings.

Scroll down to Multimedia message (MMS) Settings section and turn off "Auto-retrieve"
Next time you view the message, the message will display a download button.
Make sure your mobile data is on, and tap on the button. The image will be retrieved and displayed inline on Galaxy S.


Notification doesn't show up on Redmi 8 MIUI 11 and 12

This is usually a problem with battery optimization. Go to your settings and identify the list under battery optimization (that is the stock Android name, it could be battery saver etc). Remove those apps from the list
Edit: As confirmed by OP in comment, it is found under Settings → Battery & performance → App battery saver. Selecting those app(s) from the list, and changing from Battery Saver to No restrictions fixed the problem of missing notifications.


Is Samsung's Media Hub only available to new customers?

Appears to currently be US only, and only added in the latest Epic 4G update. However the marketing materials keep mentioning Galaxy S devices, rather than any specific models, so it could well roll out to the rest of the Galaxy S range in future updates, or possibly even via the on-device Samsung Apps store that most Galaxy S's have (assuming your phone company hasn't removed it).

However it's worth bearing in mind that this is a transparent attempt to lock you into Samsung for future phone and TV purchases, as once you've built up a large library of paid content on their media store, you're probably not going to want to move to hardware where you can't watch that content. If you're happy with that then ok, personally I'll stick to more hardware independant media vendors.


show carrier name on status bar (galaxy A5 2016)

I've been trying to do the same to my devices, and after extensive searching it looks like the only way out is to root and modify the SystemUI yourself. Refer here and here for steps on how to do this. This still works as of Android 6.0.

This will be even harder to do on Samsung phones, because their framework is tightly integrated and you might not even be able to decompile the framework in the first place.


Unable to detect Android device with ADB on Mac but can detect it through Fastboot?

EDIT: To begin with you should probably install adb/fastboot directly from Google. This is the best way to update/maintain adb/fastboot.

So you state that you have no access to the bootloader, yet you are able to issue fastboot commands and invoke at least some type of response? Then that means you have access to your bootloader my friend. Fastboot == bootloader (or Download Mode, which is essentially still bootloader). I've never had a chance to mess with your specific model, but if you're stuck in a bootloop I'd suggest trying to issue a few more commands:

fastboot flashing get_unlock_ability

this will let you know if you can unlock the bootloader

fastboot flashing [unlock] [unlock_critical]

one of these will let you unlock the bootloader (as long as nothing else prevents it from doing so)

And if you're able to unlock it, I'd suggest downloading TWRP for your device (Google = best friend), and flashing it to your phone with a

fastboot flash recovery [twrp.img]

Bricks aren't ever really a permanent mess-up, as long as you can get into some type of recovery. Even if you can't get it unlocked or flash, you may be able to boot still with a factory image (Google = best friend), then try flashing the full firmware, if it wont take, extract the boot image and see if you can force it to boot with

fastboot boot [boot.img]

let me know if any/none of these work and we can go from there. best of luck.


Import/Install SSL-certificate without CA-flag

Is it possible to install this self-signed certificate to Android without having a set CA-flag?

Android uses OpenSSL (or the fork BoringSSL in later versions) as the underlying SSL stack. OpenSSL will not accept a self-signed certificate unless the CA flag is true, because even a self-signed certificate must have the correct flags so that it can sign itself (i.e. CA flag). So even if you would be able to install the certificate it will not be used as the trust anchor for validation, i.e. the validation will fail.

  If not, is it possible to modify that existing certificate, so it can be installed?
  NOTE: Creating a new certificate is NOT a real option.

No, you cannot modify an existing certificate. You could probably re-create the certificate if you have access to the original certificate and the private key.


How can I use PSP headphones with my Android phone?

The extra part you've noticed is not USB at all: it's actually some extra contacts for the microphone and media/volume controls on these headphones. This a proprietary connector that's just for the PlayStation Portable (PSP), which these earphones were designed for.

If you break or cut off this part, you can use them like normal headphones, with a phone or anything else, but the mic and media controls won't work any more. They're not very good earphones, so you'd be better just using them with a PSP like they were intended, and getting some proper earphones to work with your phone.


Will the ''wipe data/factory reset'' in ClockworkMod also remove my backups I have done?

Wipe data will wipe everything on your /data partition (hence the name). A factory reset will wipe the same (additionally also cache and Dalvik cache), and put your device back to a virgin state. Usually, this doesn't touch the (external) SDCard, and AFAIK should not touch the internal SDCard either.

I don't know on which partition your mentioned folder resides; but if you want to be on the safe side, back up everything to the external SDCard (or even better off-device, e.g. to your computer).


Android x86: remounting /system : /dev/loop1 is read only

My guess is that you installed the androidx86 using fast install from advanced options. Please reinstall the Android x84 and select the /system to get mounted as rw as you can see in the image bellow:

PS: Even if the image is rather old it still stays the same during installation.


On S3 Mini, Heimdall ERROR: Partition "RECOVERY" does not exist in the specified PIT

I managed to solve as follows (on Linux):

Cause of problem:
In the PIT, there is no partition, called "RECOVERY" (duh). Keep in mind, the command is case sensitive.

Have a look at the PIT:

sudo heimdall print-pit --verbose

On my phone the recovery-related partition was called "Kernel2"

What worked is:

sudo heimdall flash --Kernel2 recovery-clockwork-6.0.4.6-i9300.img --no-reboot


How can I edit a Presentation in Google Drive?

I'm not sure if the mobile app offers this feature but at least via the web interface you can export your documents to OpenDocument files which you can edit locally. Afterwards, you can upload the edited version.


Here's how I did it when I needed to increase the size of my second  (ext2) partition that Link2SD used for applications from 2GB to 6GB:

Use free version of Mini Partition (v9.1) to

a. shrink the first partition (FAT32) by 6GB
b. ensure the existing 2GB ext2 partition is at the end (so that the second space after the first partition is the now unallocated 6GB space)
c. create a new 6GB primary ext2 partition in the unallocated space

Use the free version of Paragon ext2fs to mount the 2 ext2 partitions in Windows and allocate each a driver letter
Use Windows explorer to copy the contents of the old 2GB ext2 partition to the new 6GB partition
Put the card back into your phone and have Link2SD recreate the mount scripts for the 'second partion' (just to make sure the 6GB one works)
Use Mini Partition to:

a. delete the old 2GB ext2 partition
b. move the 6GB ext2 partition to the end of the card/drive
c. extend the FAT32 partition to fill the 2GB unallocated space.


Locale powersave plugin & Power Control widget

I am the developer of Locale.

To get started, please read this article on our website about toggling 3G which should answer your questions: http://feedback.twofortyfouram.com/forums/5655-locale-feedback/suggestions/67867-3g-support-for-network-setting?ref=title

From that article, I think you'll find that using APNDroid will be the best solution: it is free, has a Locale plug-in, and it contains a widget that can be used to manually toggle Internet access on the phone.


How to stop notifications of OTA update after rooting?

If you are having root, use Titanium Backup to disable/freeze CMClient.apk & DMClient.apk. This will disable the tablet to check for OTA from Asus servers.

If you want to update the tablet to latest firmware later, unfreeze/enable the apks and proceed with updating.


Something's automatically sending "stuff" from my phone

If that is a malware, it will take care to leave no tracks (i.e. deleting the sent message).

Two things you should do ASAP:

Contact your provider and check what messages where sent. Especially expensive "Premium" messages. It could be something sends "just spam", but it also could be some "money generator".
Check with a permission checker what apps have the permission to...

send SMS/MMS
deactivate your lockscreen (aka keyguard)

If you find an app that has both permissions, that's a very likely candidate. A good app to check this is e.g. RL Permissions, which lets you check by app and by permission:

RL Permissions: Apps by permissions / Permissions by app (source: Google Play; click images for large variants)

As RL Permissions has not been updated for more than 2 years, an alternative to this is Permission Explorer, which offers similar features:

Permission Explorer: Apps by permissions / Permissions by app (source: Google Play; click images for large variants)

Once you've identified a suspicious app, deactivate or uninstall it. Watch if the described behaviour continues. If it does not, you've got the culprit.

One more lesson learned: Just having some AntiVirus on your device doesn't mean you're safe and don't need to care. Those "checkers" mostly compare with a database of known malware. Unlike their PC companions, they don't do heuristic scans.


Fakestore, blankstore, gms, microg, unifiednlp - what's best for Android without Gapps?

Some basics first:

NoGAPPS is deprecated and got replaced by its successor, µG (read: microG).
µG includes the core (basically, GServices) and also UnifiedNlp.
No GService replacements will support the Google License API. That's much too hot an area. While we all love dentists, we better not see them working on us (replace "dentists" by "lawyers" in this context).
there are ways to access PlayStore, though, and you've mentioned some candidates:

BlankStore: Deprecated, no longer maintained except for bugfixes, but its successor not yet ready. Supports only free apps.
FakeStore: As the name suggests, only a "fake" – i.e. it fakes the presence of Playstore to apps not working otherwise.
Yalp: Like BlankStore but still maintained, plus supporting apps you've already bought (but not the process of buying and not the license check some paid apps perform).
More candidates in my corresponding app list.

I'm running that combination (CyanogenMod + µG with UnifiedNlp + BlankStore/Yalp) for about 2 years now. The only thing I found not working was paid apps that wished to verify their license against GPlay – apart from that, everything runs smoothly. For details, you might wish to see my article series on Android without Google. Note that, however, there seem to be some issues concerning LOS 14.x and UnifiedNlp currently; for details, please check with the issue tracker on µG's Github presence.

You can find the implementation status in the project's wiki, as well as a short introduction. In terms of privacy, you can derive from those two:

  Acting as a replacement for the closed-source Google Apps (GAPPS), it is a powerful tool to reclaim your privacy while enjoying Android core features.

(from the introduction; emphasis mine). In the implementation status, take a closer look at two columns: Functionality and Crashing. If both are "No", we have a dummy: Apps think it's there, but absolutely nothing is happening in there (especially no data transmission); this is and always will be the case for Analytics and Ads, for example. No functionality and crashing means there's nothing implemented (not even a dummy) – so apps accessing that might crash, but again nothing is transmitted (currently e.g. Auto and Cast).

If data is transmitted, to my knowledge this is limited to the absolute minimum for the functionality to be achieved. This e.g. includes Google Cloud Messaging (token, id and obviously the message must be exchanged, where the latter is usually incoming only), Account Authentication (guess what: account name and token/password must be sent for that, or there can't be an authentication), Maps API (must obviously send the desired position for the tiles to be retrieved – but this doesn't go to Google, as it uses OpenStreetMap/OpenScienceMap instead). Fused Locations doesn't run via Google either, as it uses the UnifiedNlp backends instead.


I had the same exact problem, and it was driving me crazy!
Sadly, I couldn't find any solution other than to install an app, "Sound Manager": selecting "whenever possible" in the vibration settings the vibration will work just fine!


Is there a workaround to use of bash via adb on LineageOS17?

adb shell -t bash -i


Does Android support the external USB devices?

All that depends on your device, which must support this as well. Android itself does support this since 3.1-honeycomb – and I e.g. successfully use an external keyboard with my tablets, which is just plugged into the USB port.

The keyword to look for is usb-on-the-go. We already have more than 60 posts on this topic, which you might wish to check (or start with the 9 most frequented to easier get to the core points). If those leave open questions, feel free to ask those in separate posts :)

Edit: As Dan correctly points out in his comment, if your device has a full-sized USB port, there's no need for OTG. See our usb-host-mode tag for that.


Is there any way to disable the camera beep when I start recording video?

There are several "silent cameras" available on google play, as e.g. Silent Camera and Silent Camera (and many more) for photos. I remember there was some settings app to completely silence the camera (regardless of the camera app used), but I currently cannot find it.


It could be a ROM bug - have you communicated to the author/thread of the ROM and asked if there are any issues with SMS sending?

If there aren't, I suggest that you wipe factory data completely, and then try again. You may wish to use an app such as My Backup Root or Titanium Backup to back up your apps before you do so.

what version of Android are you running?


I use DiskUsage for situations like this. It graphs the directory structure for you in a very pedagogical way to show you what directories (and subdirectories) that are taking up the most space. It literally solves situations like this in 15 seconds for me, because I'll see a big square with the text "Movies" or something on it, realizing I completely forgot I put an entire season of Wonders of the Universe on my device or something — or I'll se a folder with a name of an app that has long since been deleted with a bunch of useless cache :)

Try it out, I'm not sure how well it works on non-rooted devices but I think it should work on those as well, I don't think it does anything else than list directories and add their content size up.


ADB can discover devices but not fastboot

To make the system recognize the Android device, in their several modes, one needs to set permissions for his user in udev.

You need to repeat this process of loading Android udev IDs, for every mode the phone has (operating system, bootloader or recovery) because they have different USB IDs

# reboot into fastboot mode
adb reboot bootloader

# grab you fastboot/bootloader device ids
lsusb
> Bus 001 Device 035: ID **18d1:d00d** Google Inc.

# install the ids into /etc/udev/rules.d/99-android.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="d00d", MODE="0666", OWNER="thiago"

# restart udev
/etc/init.d/udev restart

# try fastboot (only on bootloader mode)
fastboot devices


May be your phone is bricked.

Try downloading the StockRom or some CustomRom that is compatible to your phone and flash it. This might help you.

If you are wandering about all these terms Bricked, StockRom, CustomRom and flash. Here is a good article that might help you to understand.


Well first take a look at what is your standard SMS App. If it is anything that is not native to your phone (e.d. third party App) or something you installed away from google play store (e.d. untrusted source) it can be some sort of malware.

But before jumping to conclusions it is recommended you check every app in your phone and try to see which apps are even capable of sending SMS. To check if the app is capable of sending SMS, go to your Settings -> Apps and than click on each App individually. It should display a list of permissions the App has on your phone. If you see that the app has the permission of sending and recieving SMS, but is not the App used normally for communication, uninstall it immediately. Of course, this doesn't include Apps such as Viber, because they can indeed send SMS messages.

Hope this helps.


I am not an expert on the subject but if you hold down the power key for ten to maybe thirty seconds you can get them to reboot completely. Mine got stock on a screen when i first got it. it just stock on some arbitrary screen but that I think how I got it to reboot. But I am not sure how long you have to hold down the button but it is some length of time.


The Apple EarPods are  working on my Nexus 6P perfectly, save the inline volume controls. The microphone button pauses music on a short press, and skips the current track to the next on pressing it twice in rapid succession. Long pressing it open Google Voice Search.


Can I change the language for the Android Market website?

Add the language parameter to the end of the url:    https://market.android.com/?hl=en&lr=lang_en


As beeshyams has already written in the comment, it is possible with this app.

Alternatively, another launcher can be installed. Many launchers (Like Nova) can be customized with various themes.
