What is this folder named "d1o1m0o7b1i1le"? Is it a virus?

The folder is created by (at least 1) apps developed by DoMobile Lab. As a hint, when you remove all numbers from the folder name, it spells /.domobile.

As a proof, after installing AppLock and running it, there will be /domobile and /.d1o1m0o7b1i1le folders on the SD Card root folder.

I don't think it is a virus, and it might be really important for DoMobile apps to work properly.


Google Play Store gives error "No Connection"

Solution 1
You need to uninstall(only after force stop it & clear data and cache) Freedom app in your mobile phone if you have. There are some reports that Freedom App causes "No Connection" error.

Solution 2 -
Check your Gmail / Google account password. Have you recently changed it? If yes, then you will need to re-enter your password on your Android device to get all your Google services back. As soon as you change your Google account password, your device gets a notification to enter the new password. Do it or your Google Play Store or any other Google service will not sync or work properly.

Solution 3 -
Clear the Play Store cache. The Google Play Store app on your Android device stores some cache data on your device which could be one of the reasons why you are not able to connect to Google servers using the app and keep getting the “No connection – Retry” error message. How to fix it?

Read the quick and easy steps below:

Go to Settings > Apps.
Scroll to All apps and then scroll down to “Google Play Store” app.
Open the app details and tap on the “Force stop” button.
Then, tap on the “Clear cache” button.

That’s it. Now start the Google Play Store app on your phone / tablet and it should load and work absolutely fine!

Solution 4 -
Check the date and time of your device. Yes, this was the problem with majority of users complaining about this error message in their Google Play Store app. If your date and time are not correctly set, you will again the “No connection – Retry” error message.


Wondering if i can debloat some google apps from unrooted lg phone for my father?

You're looking in wrong direction. insufficient-memory error shows up when you're running low in space under data partition (named: userdata; mounted at /data). It stores user installed apps (APKs), updated system apps (APKs), their data files inter alia. System apps by-default are stored in system partition (named: system; mounted at /system). That partition is not mounted in read-write (rw) mode and doesn't cause that error.

Removing the system apps wouldn't achieve anything since as I said, unless the system app is updated by the user, the APK would only reside in system partition. However, it would consume a bit of space to store its data files in data partition.

If that amount concerns you, then go to  Settings → Apps → All apps → your system app → Force Stop → Uninstall Updates (if any) → Clear data → Disable. This would:

disable the system app which simply means that you wouldn't be able to use it or update it unless you enable the app.
delete its data files from data partition since you used "Clear data" button. If it was updated by user, its APK would be removed from data partition as well.

Why bother with extreme measures then?

Just so you know, adb shell pm uninstall  would blatantly fail to remove a system app, regardless of whether it is running with superuser privilege.

That said, some system apps wouldn't give you disable or clear data option. But if they are not giving such option then assume that your OEM considers that the app is critical for the stability or functionality of your OS (even if it is not) and you should ignore disabling it.

If you can't ignore it and wants to take a risk, use this command:

adb shell pm block PACKAGE # for KitKat
adb shell pm hide PACKAGE  # for Lollipop

This would effectively bar that system app from being used even if it causes instability to the system. This also means that the app would never be updated again unless you revert the changes.

To unblock or unhide the app, do

adb shell pm unblock PACKAGE # for KitKat
adb shell pm unhide PACKAGE  # for Lollipop

PACKAGE → package name of your system or user app. To know the package name of an app:

for KitKat - follow View app's full package name?
for Lollipop - open Settings → Apps → All apps →  your app → click here

Save yourself all the trouble: "i keep telling him to get one but... and i dont have an extra!" -- save some money, buy an SD card, plug it in his phone when he's not around and there you go with the surprise gift.


Will an Asus Transformer Pad Infinity work in the UK if I ship it over from USA

The Transformer Pad Infinity itself would function fine in the UK. You would probably have an issue with the US charger and would need to get an adapter or charge via USB. As far as I can tell GPS and WiFi should work the same no matter where in the world you are.


fastboot flashing error: "Partition should be flashed in fastbootd"

I'm sure you figured it out by now but for any future users searching for a solution, I had the exact same issue on my Pixel 3a XL. You need the most up to date version of ADB and FASTBOOT. Grab it from Google to be sure you have the most recent, you only need the SDK Platform-Tools. Don't have to download the whole SDK Platform


Yes. You can take either of the following two approaches:

Use tubemate. With this app you can browse YouTube and download the video just like you would download from websites like keepvid.com.
The latest version of YouTube allows the videos that you opened or YouTube thinks you'll watch or have added to watch later queue to be downloaded in background so that you can watch it later. Read here. -> The preload option is no longer available in the official youtube app since version 5.6, see google support note here

  For the first time, YouTube will start downloading videos it thinks you might want to watch, whenever you’re plugged in and on Wi-fi.

  That’s great news for commuters, for example, who can now watch videos when outside their mobile coverage zone (or without paying for costly video downloads over 3G).

  YouTube, careful to draw a distinction between this and total downloading of its vids (which breaks its terms of service), is careful to point out that you’ll still need to be online for the first second when you press play.

How to use Generic USB Joysticks in Android via OTG?

You need to root your device.
Also, you need to have and install the following:

Software (APK)
1. USB/BT Joy Center

Hardware
1. USB hub with power capability
2. your generic gamepad
3. USB OTG

After the installation of the APK Insert your hub with power capability (some tablets and phones cant give enough power to the joystick).
When the USB hub lights up it is detected by the tab, all you need to do is plug your generic gamepad.
Now open USB/BT Joy Center this software will automatically detect your gamepad.
(trouble shooting) when your device is not detected. Restart your device with all the hardware connected.
When your tab is already open, try reopening USB/BT Joy Center. I think this should do the trick.


How do I root my Dell Venue 3830 tablet?

I rooted my 3730 using MyKitBatch from social-design-concepts on XDADevs. It is just a root, not a ROM so it is model agnostic. It hasn't been updated in a year but it works with the 3730 and 3830.

If it doesn't work the OP/dev of mykit created this which they also claim has 3830 support, I have never tested it.


Can an application use the microphone for two different tasks at the same time?

Can two apps use the microphone at the same time?

As far as I know: By default, the same way two different apps can't use the camera at the same time, the same principle applies to microphone too. Since these hardwares' drivers respond to only one call from one user at a time. Of course you can make an app that gets the input from microphone and then acts as a broadcaster to share the input with other apps. But the microphone itself doesn't provide for two users at the same time. Since the Phone app is also a user, microphone provides only for it. That being told, my information can be outdated. Or there can be ways to cheat in this case. User Micheal from this Stack Overflow question says:

  I don't remember exactly where the limitation comes from, but on one of
  the platforms I've worked with we had a workaround in the form of a
  stream splitter. This class was written by the platform provider (so
  it was proprietary), and was part of libaudioflinger IIRC. It would
  manage the audio hw input stream, and hand out audio data to all
  clients (apps) that wanted to record audio. So it can be done if you
  have the ability to build your own Android ROM, but it's not trivial.

So is it possible? Yeah. But seems unnecessarily painful to me. Still as I said, take my words as a grain of salt, since my Android knowledge is not very up to date.

Can an app use microphone for two different things?
An app is made of different components. User of the phone uses user interfaces (activities) to start processes that happen in the background (services) and all services have their own thing to do. Yet, they all belong to the same process that has a specific UID given by the Android. Once the given UID gets the input info from camera, microphone etc. it can use it for different services at the same time. That's up to app to decide.


By what you describe, this is more likely to be related with the proximity sensor.

It is located at the top right corner of your screen, outside of the touch area.

If anything is blocking that sensor, the screen goes black. This happens to prevent the users face from touching anything on the screen during a call.

What works for me, is either using the home button or the power button to bring the screen back on.


I've had a similar problem, sometimes the volume is at max and won't decrease, sometimes the other way around. It also started occurring on CM7.1 (but on a Galaxy S). The volume controls start responding after pressing them both ways (i.e. if volume is at maximum, increase first and then decrease, and vice versa).

You should also check if your phone's version has amplification settings in Settings -> CyanogenMod settings -> Sound or something like that.


Phone randomly cannot recognize my Wifi network

I've found the problem. Both the router and the phone was working correctly. The problem is with the Wifi channels. According to Wikipedia's List of WLAN channels, some places only allow channels 1-11, some others 1-13. Devices will provide support accordingly. My router supports channels 1-13, while the phone (I guess) supports channels 1-11. So when the router uses channels 12 or 13, the phone cannot detect the network!

Solution?

Buy another router which only support channels 1-11.
Logon to your Routers config through your browser to find whether the router supports limiting the channels. Refer to your Routers user manual on how to do this
Change the channel settings on the router to be manual (i.e not automatic), and somewhere in the range 1-11 (preferably 1 or 6 or 11).


Does encrypting an Android device add any real security benefit over a key-lock?

Decrypting the device and bypassing the lock mechanism are completely different things. The request for the PIN code/password in the standard lock screen occurs AFTER the device has booted. It is possible bypass it by gaining indirect access to the already available data. And bypassing the lockscreen password is relatively easy.
With encryption enabled, it occurs BEFORE the boot and there is NO data that can be obtained without getting the actual key. There is no bypass there, except extracting the key from you by physical force... (An obvious assumption here is that the actual encryption mechanism/software does not have obvious bugs, but this assumtion undermines ANY discussion on security whatsoever, so I'm not taking it into account).
Your phone may have an external SD Card with lots of data on it (like mine). Encryption will protect it if the phone is lost, since ejecting it and trying to mount it elsewhere will fail. That's not a "forensic-level" attack.


If you are using swipe, go to settings> locale and text> swype settings and then click on reset swype's dictionary

when the list of learned words appears, long press on one and you may be given the option to forget it. This works on samsung galaxy note 3.


Is there a way to create new files in Astro FM

After looking through the Help file and through Astro quite a bit, alas, I believe the answer is no. While it does allow for editing, the only option for creation is Directory (Folder) creation, as you pointed out.

Workaround for lack of "hide sensitive content" setting for lockscreen notifications in CyanogenMod 13?

Determine which app owns an icon on my home screen

I cannot be sure that it would definitely work in your case but a way to find out the details about a shortcut is to see the relevant entries in database of your launcher app.

E.g. If the shortcut appears on my home-screen when Android's native launcher (com.android.launcher) is active, then I would proceed to see content in /data/data/com.android.launcher/databases/launcher.db. The problem is that a normal user cannot access /data/data directly without root access.

Since the question demands usage with adb only, I would suggest taking a backup of the launcher app and extract the .ab backup using Android Backup Extractor. Now you can access the launcher.db from it. I use DB browser for SQLite to open the .db file.
Users with root access can use adb pull <SOURCE> <TARGET> to fetch the relevant file. You may try SQLite Editor as well.

The location of shortcut entries may differ amongst launchers.

In my native Android launcher and Nova Launcher, the entries are in table favorites respectively.
Smart Launcher has them in the table flowerBubble.

Once you're inside the relevant table, find your shortcut under the column title and see all the corresponding column-values there.

In my findings, custom shortcuts had iconType value greater than 0, and for some custom shortcuts iconPackage and iconResource had the values as the app's name and resource whose icon is displayed.

Note that my findings are only based on aforesaid three launchers and your launcher may not reflect similar pattern.

  [Is] it possible to determine which app created a launcher icon or shortcut [on my home screen]?

I have doubts reserved whether this is really possible. As it is clear by now, the home-screen shortcuts are (unlike traditional GNU/Linux) not symlinks since their structure varies from launcher to launcher, and usually cannot be called or executed unless the launcher itself is active (possibly because the parent launcher can only know whether the entry should be treated as shortcut or not).

Based on my findings, my answer would be no, you cannot determine which app created the shortcut on home-screen.


Why can't I copy files between the external & interal SD on an Android 4.2 tablet?

Samsung s7 only asks for fingerprint scan not giving option to enter password

I had this exact same problem on my Galaxy S6 recently.  No matter how many attempts I made in different positions, the fingerprint reader decided, as it often does, that it simply wasn't going to accept my fingerprints.  Frustrated, I had no option but to continue trying (and failing) to scan my fingers with ever-increasing timeouts because it wasn't giving me the option to type my backup password.  With only a few attempts left before it would erase my phone, I remembered that sometimes text to the effect of "Swipe to enter password" appears at the bottom of the lock screen.  Even though this text wasn't currently visible, I tried swiping (up from the bottom, if that matters) and a password prompt finally appeared.

TLDR - The problem: finicky fingerprint reader meets poor UI.  The solution: swipe on the lock screen.

Maybe you can try booting your phone to safe mode to remove conflicting apps . You can also try rebooting your phone.

What is the cause of a "No network connection" banner?

In my case the bar is gray and at the bottom. The bar is drawn over all other apps and is always visible.

To check which apps have this capability:

Open the Settings.
Navigate to Apps (under the Personal section).
Open the configuration by tapping on the cogwheel icon in the top right.
Open Special access (under the Advanced section).
Open Draw over other apps.

This already made it much more apparent which apps are candidates for this issue. The next time the issue appeared, I closed apps one by one until the bar disappeared.

In my case, the app causing the bar was Office 365 Admin.


Why doesn't Android recognize my SD card when my computer does?

There are multiple approaches to this. Not all of them are available on all devices, so you might have to "skip" some. I will list them in the "order of their convenience", i.e. easy and non-destructive things first:

Check Settings→Storage for some entry to delete/format the card
Connect your device to your computer via USB. If you're lucky, the card will be offered to it in UMS mode. Then use your computer's tool to format the card (take care to not use NTFS as file system, Android can't handle it. To be on the safe side, cards usually ship with FAT file systems)
Remove the card from your device, and use a card-reader to attach it to your computer. Format it using your computer's tool, as described in the previous example.
As many manufacturers decided to replace UMS with MTP, if none of the above works for you a downgrade to an Android version before 3.x might bring back UMS support. But that should be left as the very last ressort; after all, a card reader comes cheap. Depending on the device, there might even be possibilities to enable UMS using a hack or a specific app (provided the device is rooted), see e.g. Enable USB Mass Storage mode in LG Optimus 4X HD.

Im trying to download apps but it says insufficient storage but I have plenty of storage and an sd card

I had the same problem on my Huawei Ascend P2, I did a factory reset and it seemed to work, though I highly recommend copying over to your computer every file on your phone before even trying to do so, I don't know the cause myself, the theories I have are:

Virus
Damaged internal memory

If it still doesn't work after the factory reset then you need to take it to a specialist (unless you are one) and take it apart and replace the memory.

P.S Don't treat this as a answer as such, I don't have the reputation to comment (which I think they should allow everyone to do instead of risking losing a ton of rep).

P.S.S Have you checked to see if your SD card is being read by your phone?


Downloading and installing an application in the system/app on a un-rooted device

Root is only required if you are installing a system app within the confines of the Android OS.

If you can flash your own rom, you can bypass any restrictions that the OS has, because you are able to do anything you want with a custom bootloader before the OS has a chance to load and restrict things.

If you are creating a custom rom (off-topic for this site), you can edit the rom on a desktop and flash it to the phone.

You could simply flash a file using a custom recovery (such as TWRP or ClockWorkMod).

If you are on a stock phone with a locked bootloader, you could always root your phone temporarily, remount system as read-write, add the application, then remove root.

As far as updates go, as long as the application in the system directory is signed by your key, you should be able to update it (root not required). You'll need a way to get updates out, though. You could post in the Google Play Store, use a 3rd party store (such as Amazon App Store or F-Droid), or have the user download the app and side-load it. If you also wrote the app in question, you could probably program a way to self-update as well (also off-topic for this site).

How do I check bad sector on my android with ADB recovery mode?

You can follow these steps to check your Android NAND chip partition which checks bad blocks:

1.for your data safety,backup your data to pc or cloud first.

2.boot to recovery.

3.unmount all partition in recovery.

4.connect your phone to pc.

5.execute adb shell .

6.use cd command go to your partition directory,usual in:

/dev/block/platform/soc.0/<chip ID>/by-name

or like:

/dev/block/platform/msm_sdcc.1/by-name

for example:

cd /dev/block/platform/soc.0/12345678.sdhci/by-name

after enter directory,you can execute ls command show all partition name,like system,cache,userdata,etc.

7.execute e2fsck command with -cfv parameter and partition name,for example,you want check userdata ( /data ) partition with check bad blocks:

e2fsck -cfv userdata

or system partition:

e2fsck -cfv system

Additional Information:

The -c parameter for e2fsck is check for bad blocks and add them to the badblock list, you can execute e2fsck -h get more information.

What is the zygote process still doing in Android L?

Zygote isn't really bound up with Dalvik, it's just an init process. Zygote is the method Android uses to start apps. Rather than having to start each new process from scratch, loading the whole system and the Android framework afresh each time you want to start an app, it does that process once, and then stops at that point, before Zygote has done anything app-specific. Then, when you want to start an app, the Zygote process forks, and the child process continues where it left off, loading the app itself into the VM.

Although this method was originally designed for Dalvik, there's no reason ART shouldn't behave exactly the same way. It doesn't have to JIT-compile apps while they're running, but it still has a lot of app-independent Java stuff to load (i.e. the whole Android framework), so it makes sense to use the same fork-when-loaded method to start new processes.

It's natural on such a large project that there would be other left-overs from Dalvik that are still useful in a post-Dalvik world, so you shouldn't be surprised that there is other code that was originally written to be part of or to work with Dalvik, that is still around for ART to use.


What is Blackmart, and is it legitimate?

Even if the pure Blackmart App is free of any malicious parts, there is still the danger that you will download an infected version. Blackmart has no official page or download site, that's why you can't be sure about that. It's even worse because it needs root. Those types of programs are usually not open-source, and therefore no one can review the code or even build a "clean" version.

Note: Since Blackmark is able to bypass the access restrictions for paid Apps, it's is illegal in some countries. This is likely true in all countries where Google sells Apps on the Play Store.

My personal opinion: A free game of Modern Warefare or GTA isn't worth the trouble and risk of using blackmart.


This would be better as a comment, but I don't have enough reputation for that. I'm happy to help you troubleshoot though!

Basically to answer your question it would help to have more information. How did you root your Nexus and what version of root are you using. How did you install bash and nano?What is your TERM variable set to? Are you using a terminal emulator or adb? If an emulator, which one and what is the terminal type set there? (Look in settings). If you set both of these to something nano can handle this might solve your problem.

Also Google your error message and "nano" - it seems others have had and solved similar problems.

By the way rather than responding to me it would be better if you changed your question to include information about what troubleshooting steps you took. If we solve the problem I can also edit my answer to fit the solution.


Any way to download swf files on android?

I download the page it's on as HTML, find the link to the file, and then use ES's Download Manager to download it. But that's just me.

How to upgrade my AnkiDroid flashcards from 1.x to 2.0?

How to upgrade to AnkiDroid 2.0
Introduction
With the release of AnkiDroid 2.0, you need to upgrade your decks to the new (significantly improved) Anki 2 format. Besides upgrading your decks, you also need to upgrade to version 2.0 or later of Anki on your desktop if you use it. Anki2 brings a number of fundamental changes to the learning style which also affect AnkiDroid. Please take some time to read about them here.
Upgrading Decks
This guide is for Windows users; please allow 15-60 min to do this depending on your level of familiarity with Anki/AnkiDroid/PC.
If you are still having trouble after following this guide, post in the forum for personal assistance.
Please ensure that you have the latest version of AnkiDroid installed!
Part A: Backup old AnkiDroid files to your PC

Connect your device to the PC with USB cable
Open windows explorer and click on your Android device
You should see a folder called "AnkiDroid" listed in your device
Copy this "AnkiDroid" folder to your Desktop
You should see all of your decks as DECKNAME.anki files. If not, go to the backup folder and copy and paste them into the AnkiDroid folder.

Part B: Upgrade old decks with Anki desktop software

Install the latest Anki desktop software from http://ankisrs.net
Open the Anki desktop software that you just installed
In this Anki desktop software go to file->import
Now navigate to to Desktop/AnkiDroid -> Change ("Files of type" > "Anki 1.2 Deck") -> Choose the first .anki deck
Do the same thing for each .anki deck in the AnkiDroid folder
Check that all of your decks are now listed in the main Anki software

Part C: Copy the upgraded decks back to your device

In Anki Desktop software go File->Export and click "Export" button
You should see a message saying a file called "collection.apgk" has been saved on your desktop
Go to your desktop and copy the "collection.apgk" file
Now open your mobile device again with windows explorer
Navigate to the AnkiDroid folder
Right click and paste the "collection.apgk" file
Now open AnkiDroid, open the menu and choose "Import cards" then click OK
Now you should see all your decks there ready to start reviewing.

Part D: Move any media on your device to the "collection.media" folder
This is not necessary if you don't use media

In windows explorer open the AnkiDroid folder on your Android device again
Confirm that there is a folder called "collection.media" and some other folders that look like "deckname.media"
Open the first "deckname.media" folder
Select all files (press Ctrl+A on the keyboard)
Right click and Copy
Now go back and open the "collection.media" folder
Right click and paste
Wait for all the media files to finished moving
Repeat steps 4 to 8 for each of the other "deckname.media" folders
Confirm that all your media files are now in the "collection.media" folder
Optional: you can now delete the "deckname.media" folders if you like since these are not used in AnkiDroid2

Note: This method can't handle different files with identical names.

com.android.systemui rapid battery drain

I haven't figured out what was causing the problem, but I did manage to fix it. I restarted my S5, and the process that was consuming all of the battery seems to have stopped. com.android.systemui is only responsible for 4% of the battery drain after restarting and recharging.

Possible to share mobile internet (tether) while connected to existing wifi network?

Maybe I am not understanding correctly, but you could set your phone as a Mobile Hotspot and configure a wireless router as a bridge between your existing network and the hotspot. In this scenario, all devices on your network would be using the wifi signal of the router and only the router would need to be configured to reconnect to the hotspot.


To expand on @RossC's comment, doing this yourself is quite easy if you are confident and comfortable with device disassembly, and have the correct tools. There are tutorials on how to safely and correctly replace this:

iFixIt: https://www.ifixit.com/Guide/Motorola+Moto+X+Battery+Replacement/16974
ETradeSupply video: https://www.youtube.com/watch?v=Fd3AZSXhOf8

From experience, I strongly suggest you watch the entire video and/or read the whole article before ever even starting. That way no surprises creep up on you, and you already have an idea as to everything you'll need to do.

Tools can be found widely online and may be worth the investment ($2 kit on Amazon, $1.35 kit on eBay).

Note that this might void any warranty you have from Motorola or your device's distributor. You could check with them first and see if the repairs might be covered for free or a fee. Motorola can always help but may cost you more money (if you are at fault for the damage) or can take a while to complete due to shipping, service backlog, etc.

How does Firefox Mobile decide which text to scale up?

Possibility text-size-adjust which is non standard and that's why not detected using other browsers
Extracts from MDN document

Because many web pages have not been developed with mobile in mind, smartphone browsers differ from desktop browsers in the way they display web pages.....

Because text that has been scaled down to fit a small screen is very small, many mobile browsers apply a text inflation algorithm to make the text larger and more readable. When an element containing text uses 100% of the screen's width, its text size is increased until it reached a readable size, but without modifying the layout.

This property only works on smartphones and some tablets


Do I need root to install xposed modules?

You don't need root to install xposed modules and you can avoid using root to install the framework if you have a working recovery that can install unsigned zip files.


I had the same issue and have now found the answer! The answer is that the version of Whatsapp which you used for restoring chats is not automatically reconnecting nor updating from the play store.

First of all, make sure you have made an internal backup of your chats, easy because backup to Google Drive no longer works.

Now uninstall Whatsapp - no worries, your content is backed up on the device.

Go to the Play Store and select Whatsapp. Install it.

Whatsapp will go through all the motions and find the local backup. It will ask to import it - allow that.

As a last step, the new Whatsapp will ask to connect to Google Drive for periodical backups - just answer what you prefere here.

Go have a look in Google Drive and see Whatsapp now appears once again in the list of connected apps.

All done!

How to identify the cause of entering Safe Mode?

Turned out to be a hardware fault in this particular circumstance a faulty connection between the flex cable that connects the volume buttons and the motherboard... Reseated the connector and 'safe mode' was gone next time I restarted.

Found this by trial and error - don't know of any way to narrow down the cause with the help of software.

So wish I had checked that connector before I went and wiped everything... Doh!

How to flash a factory image onto a Nexus 5x with locked bootloader?

The only possible way for you to get "OEM unlocked" is to freeze your phone and then turn it on, hoping that it will boot normally again. (Put phone in an airtight plastic bag and place it in freezer for about 1h.)

However, the Nexus 5x bootloop problem is a hardware problem which cannot be fixed using software. (One processor core is broken and as it is turned on during boot, the device crashes.) The XDA work-around simply disables the broken core, I think, but this leaves you with a slower phone.

Since you don't need to save any data on your Nexus, I'd spend my time finding a (cheap? second-hand? lineage-os/treble-ready?) replacement device.


Can I convert Samsung Omnia WinMobile to Android OS phone

The answer appears to be a yes. But we need more information about your phone. Exact model number, carrier, CDMA or GSM, etc. The more specific you can be about the phone you have the better.

Typically the process for getting Android on a WinMo phone is this, unlock with a custom bootloader, install a newer radio (not always required, depends), install a custom ROM, and then install Android using your preferred method. You mileage will vary as the process for installing a custom ROM differs for each phone manufacturer.

There are 2 main methods. 1 install HBOOT and run Android from the SD card and memory. This is preferred by me and many others because it doesn't disrupt the actual phone itself, rather it runs on top of your WinMo phone. This means you can keep your WinMo phone in tact and can easily go back to it any time.

2 flash Android ROM over WinMo and go full Android. This method is more risky because you are flashing a completely different OS over whatever WinMo ROM you had installed. So there is no easy way to go back to WinMo. You would have to flash a WinMo ROM and start over to go back to it. This method is a more permanent Android running on a WinMo phone solution.

I would recommend the 1st method first. Then go from there. But personally I never flashed Android on a WinMo phone. The other method was way too convenient for me.

I have some links below that should help, but your version of your phone is going to be key. DO NOT start downloading files and running them until you understand that your phone version is supported by the tools you are using.

http://forum.ppcgeeks.com/showthread.php?t=103190&highlight=install+custom+rom

http://www.modaco.com/content/i9x0-omnia-http-omnia-modaco-com/289028/project-andromnia-android-on-omnia/

http://andromnia.net/

It looks likes the i900 and i910 are well supported, so if you have one of those you should be good to go.

How to identify the Whatsapp sender of a media while playing it from the gallery?

You can take a look at media's metadata. If the sender's name is there you can identify it that way. Otherwise you can ask WhatsApp developers to add sender's name into the title or something. Or if you want you can manually sort the files.

It's all up to the app.


My guess - it's a refurbished device

OEM's typically ship devices at about 40% charge or little more as that is the ideal charge level for storage (from the OEM to your hands it can take months ). After refurbishment, this was not done and the already low charge dropped to near zero
During refurbishment, previous owners data is wiped out (factory reset) and possibly in your case it was done through the recovery options and carelessly not booted back to normal

To confirm , try using Phone Info -Samsung which has an option to check whether your device is refurbished (I haven't owned any Samsung device for a while, so I don't know if it works on your model or not)


Not as far as I know; it's name is just "Browser". To distinguish it from the other browsers, sometimes I call it "stock browser".

btw, it's called Firefox now (or Firefox Mobile), and no longer Fennec.


As far as I know, reverting the android encryption is impossible, you will have to backup your information and perform a factory reset.


Family Link not available on OnePlus One?

As per https://families.google.com/familylink/device-compatibility/ the child version of Google Family link requires mostly Android Version 7.0 and newer, with a few exceptions.


i wanna access the internet with my tablet via the second device

Depends on the other device.

There must be an option for sharing the internet over bluetooth in other device's bluetooth connection settings.

If you turn it on, you can connect to internet on your android tablet.


I think the USB port of your phone is defective. IMO it's best you get it replaced while warranty is still active(Samsung offers one year warranty)


Ext4 partition clockworkmod recovery backup

Most secure way:

Backup all apps with their data with TitaniumBackup. Backup all data from sdcard.
Delete some apps to free space on device's memory.
Check if all transfer-checkboxes in s2e are available now. If not - free up some more space.
Transfer ALL apps, data etc back to device's memory in s2e.
Format sdcard again with setting sd-ext partition size bigger or equal than current.
Restore all data to sdcard.
Reconfigure s2e WITHOUT ticking "mount as ext4" option!
Restore all apps in TitaniumBackup.

Please, be very careful. I'm not responding for any damage or data loss.

Please, correct me if something missed or excess here.

HoverChat has an SMS backup feature. It saves all your SMS in a .ninja file, then you can send it in a mail. You must have HoverChat if you want to restore your backup afterwards.


Android wifi (oreo) dropping. Because of pihole?

I have a similar if not the same problem - my S7 (Android 8.0.0) works fine with the exact same setup that you have until "the next morning": I have to disconnect and then reconnect to my WiFi in order to access the internet (or get proper DNS resolution?).

I could not yet find out the root cause (is the DNS changed/lost?), but I just installed a network analyzer (called "Ping & Net") in order to see if the DNS server on my phone is lost over night.


Update Market Application to Google Play Market Application

Try clearing the data for the Market and rebooting the phone.  Then log in to the Market, wait a minute, then back out and continue using your phone with the internet connection active.  Hopefully the Market should update itself within a few minutes.

Or, you can just download and install the .apk.  I rely on Android Police for the latest version; they've posted 3.9.16 here.


Remove word from autocorrect - Six Android versions and three phones later

When you type in "don't" try holding your finger on "Dont". You should get something along the lines of:

Press yes, and you should be sorted!


It will not work unless your mobile supports it.
OTG requires a source of power that need for it to work. Some mobile devices fails to provide enough power for OTG to power up the USB drives etc.
I personally tried in dozens of my mobiles and tablets. Nothing worked!

not sure about rooted devices


What do you mean by USB device for internet connection? Are you using a dongle with a SIM card? If so then those dongles need their respective software to connect to PC which are (in most cases) only available for Windows.

If that is not the case, try these steps.

In a terminal, type:

sudo vi /etc/init.sh

add 4 lines below to init.sh

netcfg eth0 dhcp
echo nameserver <ip> > /etc/resolv.conf
dnsmasq
setprop net.dns1 8.8.8.8


Any app with the permission ACCESS_FINE_LOCATION can trigger GPS – unless you've explicitly switched off GPS location with your device settings. To scan for possible candidates, you can use a Permission checker. There's e.g. Permission explorer which allows you to browse installed apps by permissions, so you can limit your watch to relevant candidates.

Permission Explorer: categories, apps by permission; LBE (source: Google Play; click images for larger variants)

If your device is rooted, there are also other means. I'm e.g. using LBE to protect my privacy. Concerning location, I can restrict on a per-app base whether an app can always access it, never access it, or I want to be asked when it tries. The latter method should definitely bring up your culprit – and even in case you missed the event, there are always LBE's logs (accessible from inside the app) you can check.


How to disable popup/heads up notifications globally in Android 9 Pie?

My S9+ is running Androud 10 UI2 and Telegram 6.0.1
I had the same issue which I finally solved. I went all through the app settings, then i tried android-apps-telegram settings with no luck.
I finally looked in android-settings-notifications and down at the bottom it says "looking for something else?" Click on the Smart pop-up view option and shut telegram off.


How to turn off the animation when locking screen on Nexus 5 running on KitKat?

As pointed out by a comment on the question itself: GravityBox, a module for the famous Xposed framwork, can be used for this (and for many other things: it's a feature-rich toolbox): you can select a different effect, or even switch it off.

If you're on a custom ROM, however, the dev doesn't recommend using GravityBox, as it might lead to conflicts (many of the tweaks GravityBox offers are already present in custom ROMs). In that case, simply search the repo for other CRT related mods – there are several of them dealing with this. One example would be XBlast Tools, which explicitely mentions: CRT Screen off effect (No Effect,Horizontal Effect and Vertical Effect) in its list of tweaks.


Yes, you need an OTG cable. The pin layout is different than a regular micro USB to USB cable; essentially, it's equivalent to shorting pins 4 and 5 on a normal cable. This is what causes the phone to know that it needs to be the host rather than the slave.

In fact, you can do this yourself if you're handy with electronics and have a cable you don't mind taking apart, though they're also readily available at many online retailers (Amazon, Newegg, Monoprice, etc).

Don't remove it. It is a logger by MediaTek and it is safe. You can access related settings by typing *#*#3646633#*#* in the dialer.
You can find a log option to enable logging. By the way, it is not very useful for the end-user. It is there for debugging purposes for developers.


Sense 4: How to add items to pull down menu?

I cannot check you image (corporate proxy forbids), but I take it you mean those "toggle buttons" to switch on/off things like Wifi, Bluetooth, etc. In this case, you can do so e.g. with Elixier (first picture1) or Notification Toggle (second picture2)

Some Custom ROMs also come with something similar pre-installed, as e.g. CyanogenMod does.


How to copy and paste an event in Samsung Galaxy A7 S-Planner running KitKat?

It would be great if this function was added again... sooooo frustrating.
It existed before:

here's a print screen from my galaxy S2 running android 4.1.2 (Jelly Bean)

Now on my galaxy S4 running android 5.0.1 (Lollipop) it isn't available anymore:

For Kit Kat I don't know... don't have any device using it unfortunately. But if it doesn't appear in the popup menu when keeping finger on the event, it's likely that it has been removed since that version.

Hope this helps and that this function will be added again in the future.


How to get rid of Sprint's notifications for ad-supported voicemail

Accept the update, it doesn't charge you unless you subscribe to the premium package. Aside from that, you could decompile the apk and remove the push notification for updates.


Execute permissions on the SDCard is blocked for that reason.
See this:
/dev/block/vold/179:1 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,**noexec**,relatime,uid=1000,gid=1015,fmask=0602,dmask=0602,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

The noexec part of this line emphasized with two asterisks is the key to prevent any execution of scripts/binaries from the SDCard.
Have a funny feeling this was answered before...deja-vu
Edit
Yup @Izzy has answered this before and here as well.


Can there be problems if I leave my old android phone alwys plugged to electricity?

Almost all concerns with phones remaining plugged in indefinitely stem from the health of the battery. Mentioning that the device is old and has a worn battery (and odn't want to deal with charging it constantly) means we can ignore those potential challenges. Refer to the question that user "dr01" linked if you want more info on that.

As for damaging/overheating your phone - that depends on your device and what your usecase for it is. Using it as a mini media centre and router will make sure it's at least warm all the time - but shouldn't cause any damage to it if the device doesn't have a history of being hot under normal use.


Do fast charge technologies wear down the batteries quicker?

In theory, yes. Charging quickly means there will be more heat produced which is bad for the battery cells.

However, most batteries are equiped with controllers that make sure that the charging process runs smoothly to avoid reaching temperatures that would be detrimental to batteries.


Use mobile internet though connected to WLAN

The solution was to let the Android device create a tethering Hotspot and make the PC/Pi connect to it instead. Then the Android device is able to connected to the Webserver on the PC/Pi while still beeing able to talk to the internet. Additionally the PC/Pi is able, too.

After update to GRJ90 I can no longer use WiFi hot-spot

Sprint tells me that I need to pay for a hot-spot plan for $30, but there has to be a way around this besides rooting my phone and putting Cyanogen on it.

Sprint clamped down and disabled the previously free built-in tethering with the latest update. If you want USB tethering you can try PDANet, but wifi tethering will almost certainly require you to root, as it does on other devices.

Even with root, you don't necessarily need to use CyanogenMod if you don't want to, though; you could just as easily install a free tethering app (one example). This has been covered here a lot, in fact, so you might want to take a look at any wifi tethering apps noted in other questions.

See also: Is there a way to enable WiFi-tethering without root access?


Im sorry, i dont think there is any other option. The KitKat update for Galaxy S3 on AT&T is only downloadable via OTA (Over The Air). You cannot update for some unkown reason, that is, unless you are willing to FACTORY RESET your phone in order to be able to update.

(there is another VERY COMPLEX WAY on fixing this, it will involve ADB, Rooting, Putting your phone at risk, and voiding your warranty.... So i would not reccomend that, but tell me if you STILL want me to tell you the other way. But please note that you would be putting your phone at risk.)

Which version of Xposed should I use for Nexus 5X?

The LG Nexus 5X is the first device with Android 6.0(.1) so it's running SDK23.
X86 is only for x86 processors, which except for the ASUS Zenfone, no one is using.
ARM is for usual 32-bit ARM processors (and 32-bit ROMs). This was the standard about 1/2 to 1 year ago.
ARM64 is the newest generation of 64-bit ARM processors and ROMs supporting this architecture. I suspect your phone is 64-bit capable (at least the processor is).

Head over to the official Xposed thread on XDA:
http://forum.xda-developers.com/showthread.php?t=3034811

The 2nd and 3rd columns list the app's owner, while the 5th column contains the app's package name.  Find the line corresponding to the "app_132" from your logcat entry, and the package name will help you figure out the responsible app.

Once you have the package name, try searching for it in the Google Play Store.  Just use the link https://play.google.com/store/apps/details?id=xxxxxxx, where "xxxxxxx" is the package name you found.  For example, on my phone "app_70" corresponds to "com.android.chrome", which corresponds to Google Chrome browser in the Play Store: https://play.google.com/store/apps/details?id=com.android.chrome


Will factory resetting wipe/clear away pre-installed apps?

What is factory reset?
First, the word "factory reset" might be a bit misleading -- as one can easily tell by your first comment to your question: If the device ships with Gingerbread (Android 2.3.x) pre-installed, and after a while offers an update to e.g. Ice Cream Sandwhich (Android 4.0.x) which you perform -- a factory-reset thereafter will not reset it to Gingerbread.
To understand what happens at a factory reset, you need to know some of the way Android's file system works. To make that easier to understand, I will abstract (and simplify) this a bit:
There are multiple partitions created on the storage of the device. A few examples include:

/system, which normally is "read-only". Here the Android System incl. its pre-installed apps reside
/data, which is "read/write". Here go all the user's data, incl. the apps (s)he installs

There are some more partitions, which I will ignore for this example. With a new device, /system contains the Android system plus pre-installed apps, as stated above -- while /data is empty. That's the "factory state", we could say. Now you switch your device on, and go through the wizard: creating/configuring your account etc. These data are stored in /data. So will the apps you download from the playstore, etc.
A factory reset now will return your device to "factory state": it will wipe all data it can.

As /data is read/write, it will get wiped.
/system is read-only, so it won't get wiped. This includes the pre-installed apps.
Your Google Account data have been stored in /data, so they will get wiped
Apps you have installed from the playstore were stored in /data, including their settings and data -- so they will be gone as well.

The Google Account linked
As you can see from above description, a factory-reset will "unlink" the connected Google Account. In my eyes, that's like I want to delete a file: sure, when I format the entire disk the file is gone... So there must be other ways which keep your data intact.
At least in earlier versions of Android, there was a different approach (not sure if that still works, though). As a factory-reset as the "last ressort" would either delete all your personal data, it does no harm to try the following in advance: If it still works, great -- if it doesn't, you still can do the reset:

from your homescreen, open Settings → Apps → Manage Apps
one after the other, open all Google apps you can find (GMail, Playstore, GTalk, Google storage...) and press the "Delete Cache" plus "Delete Data" buttons. If they are greyed out, you might need to "force stop" the app first (there's another button for that)
reboot your device

If this trick still works, your account should be gone by now; maybe even the wizard will pop-up again automatically.
Side effects
One thing to keep in mind when changing the linked Google Account are your payed apps. They are bound to the account you've bought them with -- so they might stop working when that account is no longer there, and most will do so. If you no longer want to use your old account, you need to buy them again.


does it really work? rekey.app claims to protect agains Master Key vulnerabilities

I'd be extremely worried there!

The MasterKey vulnerability exploit works in the handling of ZipEntry (see below - Bug 8219321), which is buried deep in the ROM itself, its used in the PackageManager layer as well.

For such an application claiming "to patch" it, is misleading and false, because it is a user application and not at system level.

The real cure to get around the vulnerability is to modify the source code in Android in itself and rebuild the ROM.

The vulnerability exploits ROMs from Donut (1.6) right up to Jellybean (4.2).

In the FAQ of the app's website - this made my hairs stand up:

  Can I trust ReKey with root access on my device?

  Did you see those seals up above? They look pretty darn official and
  trustworthy. They have Latin phrases and everything.

I really do not know whether to laugh or cry!

Dynamically patching the bytecode in the Android's Java DalvikVM (Runtime engine to the uninitiated) is unheard of.

Verdict:

I would take those so-called "claims of a user-level app" patching in Masterkey exploit, with a pinch of salt and not get fooled by it.

Source:

Masterkey Exploit (I) - Bug 8219321
Masterkey Exploit (II) - Bug 9695860

Patches:

Bug: 8219321 - Remove duplicate entries in Zip.
Bug: 9695860 - unsigned Zip Entries.


How can I recover files from a phone that won't boot?

I had the same problem with stock Nexus 7 2012 GSM.

The relevant documentation for this is

https://support.google.com/nexus/answer/4596836?hl=en the Recovery mode section
https://developers.google.com/android/nexus/images section Flashing instruction (it helps you get familiar with adb and fastboot)
https://developer.android.com/tools/help/adb.html ADB manual

First of all, the bootloader has to be unlocked.

fastboot oem unlock

Unlocking the bootloader deletes user data on the device (as a security precaution). If you haven't unlocked the bootloader before, you are now out of luck. Try to find if you have backups. (Contact data may be synced with your Google account, you might have Dropbox installed, G+ backups photos and so on).

Assuming unlocked bootloader, you can flash a custom recovery which will allow you to access data on the phone.

I tried ClockworkMod, but after I booted into it, adb listed my tablet as unauthorized device, similarly as this person describes. He solved the problem, I did not.

Therefore I next tried TWRP recovery.

fastboot flash recovery path_to_twrp.img

With TWRP, adb devices listed my device with recovery permissions (whatever it means) and I could copy out my data

adb pull /data .

In addition TWRP seems to enable MTP on the device. That is another possible way to get data out. I haven't experimented with it, because I did adb pull first and I got my data that way. Additionally, in my experience, MTP clients for Linux are rather flaky.


Is it possible to have separate user accounts in an Android tablet?

CyanogenMod has Profiles, but they are not profiles like you are asking. They have more of profiles for the type of notifications and sounds that can happen when that profile is enabled.

Supporting multiple users has been discussed before, and I think that it is something that is needed as well. If I buy a tablet, and set it up for my email, calendar, etc. I don't want that device to be a community device. Which would mean that multiple tablets would be needed in a family household.

A problem with being able to support multiple users is the space required. If each user had their own settings, then the /data/data would have to be much larger to support these extra users. But not only settings, it would have to support all the apps installed by the user too, so /data would have to be much larger too. You couldn't use the same apps between users, because the paid apps are tied to the account that bought them.

I think this will eventually happen, but much larger storage would be needed for the devices. As it is, my device consistently fills the /data/cache and I have to clear that out because of the number of apps I have installed. Now just imagine have 2 (or more users) using the same device. And where do you set the limit on the number of users that can use one device? There are 2 adults and 3 teenagers in my household. So that is 5 people that could potentially be using one device.

I actually experience issues with Google TV about this very topic as well. It doesn't, currently, have gmail, or apps like that, installed, but I can log in to gmail via Chrome Browser, and then if someone else comes and uses the TV/Browser, now I am logged in. (I don't actually do this, but I noticed it to be an issue with services like youtube and such)


Can I prevent Android from booting in Safe Mode altogether?

Right way to do this

Disable the broken VOLUME DOWN key by editing /system/usr/keylayout/gpio-keys.kl and /system/usr/keylayout/Generic.kl as root and commenting that key out. Longer instructions on this answer.

Dumb and hacky approach that sort of worked for me

This is an ugly solution but it works for me. It is a "tethered" solution requiring adb to do repeated "soft reboots" (restarting the Android Zygote process).

This bash script repeatedly restarts the Android Zygote process until it detects that the device isn't in safe mode. Takes about 20-50 reboots until my device randomly gets lucky and doesn't restart in safe mode…

#!/bin/sh
n=0
g=0
while true; do
    safe_mode=$(adb shell dumpsys display | egrep -o 'mSafeMode=\w+' | cut -d= -f2)
    case "$safe_mode" in
    true)
        n=$(( $n + 1 ))
        g=0
        echo "In safe mode, rebooting (try #${n}) ..."
        adb shell "su root -- killall zygote"
        ;;
    false)
        g=$(( $g + 1 ))
        [[ $g -gt 2 ]] && break;
        echo "Appears not to be in safe mode, will check again ..."
        ;;
    *)
        echo "adb shell dumpsys display failed" ;;
    esac
    sleep 15
done

adb shell dumpsys power | grep -q 'mScreenOn=false' && \
    adb shell input keyevent = POWER

echo "Escaped from safe mode after ${n} reboots. Whew."

This related question and this answer gave me what I needed to figure it out.


Where in the Nexus 4 is the wire wireless charging coil?

The charging coil is embedded into the back panel of the phone and is located directly over the battery, as shown in steps 7 and 8 of IFixIt's teardown.
The battery isn't quite non-replaceable, as the above mentioned teardown shows.  It's somewhat involved to replace it (you'll need a Torx screwdriver, a Philips screwdriver, a plastic opening tool, and some patience), but it's perfectly doable.
If you're wanting something that will work for sure, the official wireless charger would probably be your best bet.  However, it's not exactly cheap at $50.  I personally use this charger with my Galaxy S3, which I added a wireless receiver to.  I find it works well and charges right through my lifeproof case.


Boot loop after updating HTC One M8 to Android 6.0 Marshmallow

Mine does this occasionally, the temp solution I have found for the time being is to plug it into a charger and then to force a reboot again by holding power and volume up together until it restarts.

This normally gets the phone to boot, no idea why it makes any difference but it seems to work and just went back into the loop each time until I plugged my charger in first.

And no my battery wasn't low, it had 87% when it finally booted up and was at 98% when it decided to go into a loop.

Hope this helps


Make phone running Android 2.3.3 re-download configuration settings from ISP

According to this page you can obtain your provider settings by sending an SMS with just the word "Five" to 2211. Most providers have a number you can send text messages to in order to receive the settings again.

If that fails, you can try to manually configure your access point to use the following data (taken from this page):
Navigate to Settings > Wireless & networks > Mobile networks > Access point names, then press the menu button and select "New APN". Then enter:

Name:      Etisalat
APN:       wap
Proxy:     *not set*
Port:      *not set*
Username:  *not set*
Password:  *not set*
Server:    *not set*
MMSC:      *not set*
MMS Proxy: *not set*
MMS Port:  *not set*
MCC:       413
MNC:       03
Authentication type: None
APN type:  default,supl
APN protocol: IPv4

Then press the menu button and select save.

If that doesn't work either, you can find a lot of alternate configurations on this page.


Partially dead digitizer - any way to change slide to unlock?

As pointed out in my comment on the question itself, you might try a lock screen replacement from Google Play that might let you customize where to place the "unlocker". Just picking some examples by their screenshots:

LockMenu / Zipper Lock screen / WidgetLocker (click images for larger variants)

As you can see, there are multiple solutions available letting you define where the slider (or whatever) should be located – so you should be able to leave out the "dead spots" easily.


Apps Disappearing from Home Screen and App Manager

I can't tell why your apps disappeared, but I think you're not able to reinstall them because of leftover data files. I used SD Maid to delete data corpses, in order to be able to reinstall some apps after flashing a rom.
Once installed, go to CorpseFinder, scan and then delete the corpses you find. You should then be able to reinstall your missing apps.


cell phone make screechy noises while on call

There are three reasonable possibilities:

Your phone has a problem, most likely hardware.
Your service provider is having problems.
Your phone is not fully compatible with your service provider.

Possibility #1 is the most likely.

To check for #2, call your service provider and see if they are having issues.  To check for #3, ask your provider if your phone is compatible with their network.


What ROM will turn my Verizon HTC One M8 into the same thing as the unlocked dev version?

This looks like what you want. Basically, any ROM that says it's a "GPe" rom or a "Google Play edition" rom will be what you're after. To get the Google Apps you'll need to flash a GApps package such as the ParanoidAndroid ones - you can just choose the "stock" package. Flash those after flashing the ROM and you'll have a pre-rooted, dev version ROM.


Does using an unofficial charger negatively affect overall battery lifetime of a GS4?

I shouldn't think so. Samsung is a signatory to the EU Common External Power Supply standard, which includes specs for a USB charger. As long as the charger you're using supplies something close enough to what the Samsung one supplies, you're good to go. You can even charge it from a Computer USB port, although it will be quite a bit slower (except some PCs which can supply a higher amperage via a micro-usb cable, making it almost as quick as a mains adaptor charger.)

But in any case, you should be fine as long as the charger is of decent quality and isn't going to catch alight or something. I've been mixing and matching HTC, Samsung, and Blackberry chargers for years now.


Where does Google Play Music v5 store music locally?

My Google Music 5.3.1317M.940995 running on a Nexus 4 with CM11 stores the mp3 files under

  /data/data/com.google.android.music/files/music

You need root to access that directory.

A older version of Google Music on a Galaxy S stored it on the SD card. And, as I read in the official changelog, Google Music 5.x seems to be able to use the SD card as storage too. Which makes sense for devices with low internal storage space (/data/data).


Difference between drive, file manager, and downloads on my android phone?

With Drive you can view and manage files stored on your Google account. Those files are also accessible on Google Drive website.

File manager lets you browse your phone's internal storage, SD card and USB OTG storage, if supported by your device.

Downloads app only shows files inside default downloads directory (which is usually called Downloads and is placed in your default storage). So you can access files you have downloaded earlier using both Downloads and File manager.


I had trouble with my gps on Samsung S6 ( using STRAVA) after an update. Times and routes were out of whack. I fixed the problem by turning off my Battery Power Saving in the settings under battery. This was causing problems with "ok google" as well. Now all is ok. Hope this fixes your problem.


fastboot flash = FAILED (remote: invalid bootloader image)

It looks like you've got the wrong factory image. You're trying to flash the bootloader for flounder (which I believe is for the Nexus 9). You need to download a Nexus 5 factory image which should contain a bootloader called bootloader-hammerhead-hhz12d.img (or similar)


If you only want to know what app you started how often, this is easiest accomplished via your dialer (no kidding!). Just dial the "magic code" *#*#4636#*#*, which will open a menu like this:

Here you simply press "Usage statistics", and it will present you with a list of your apps and how often you started them.


That option is removed in Lollipop. If you want to use other equalizer, you have to disable default equalizer from Settings -> Applications-> All -> MusicFx -> Disable.

When you opens the equalizer from music player, it will open a chooser by showing other equalizers in it.


Smart Lock not working, is it due to Outlook?

I've discovered that Outlook Exchange server overrides my smartlock settings on my Android device. I used the default built in Samsung email client to setup my 2 Outlook exchange emails and my smartlock now works as advertised. I would like to find the settings in the Outlook exchange server to defeat this, but so far I can't find it. I am the admin for my own email service from Godaddy and Office 365. So far I can't find anything on a Google search that will direct me to the settings. I still have my Google MSN and ATT emails setup in Outlook and they don't seem to interfere with my Smart lock settings, but now I am split between 2 email clients on my phone.


You should see a notification icon in the bar at the top of the screen.

Swipe down and you can click on the notification to load the application that generated it.

In addition you can install SMS Popup or something similar to display the details of the SMS on screen immediately. I haven't found anything like this for email though.


How can I sync specific Google contact groups?

Possible options, though not ideal ones:

Flash a custom ROM that uses the vanilla Contacts app
Export your contacts from Google and import them manually (shut off sync)


Can't disable password on Android 6.0 (EMUI 4.0)

Thanks to xavier_fakerat's comment that mentioned Android Central Forum. You need to do this:

Set up a pattern password with a backup PIN
Double-tap the power button to activate the lock screen
Do wrong patterns 5 times (at least 4 dots touched to be counted as an attempt), then wait for the cooldown
Select backup PIN, enter your PIN and you could select "none"


Unfortunately, you don't have such command right now. But you can expect it to be added in the future. Google is already working on it. More information here.


How do I stop Play Store from randomly opening when I'm in other apps?

Are you clicking on ads inside apps? Because they would pop-up Play Store immediately. Remove all those apps which pops-up ads very frequently. If no - try signing out of the Play Store and stop it forcibly using App Manager. Then start it and login again. Post what happened.


It does not turn off by default, but you can change that option in Settings>WiFi>Advanced


Moto G3 (6.0) - Can't access files, tried many guides

The Moto G 2015 has known issues with this, and there is a fix most of the time...

Disconnect the USB cable
Navigate to Settings - Apps
Press the Overflow Menu (3 dots in upper right), and select Show system
Find External Storage and Media Storage
Open each item and select Storage
In this screen for each app, press Clear Data
Reboot
After the system appears up and working, wait a minimum of 5 minutes after the phone is fully booted. Databases are being rebuilt for these applications, if you have large SD card with lots of media files (several thousand or more) this may take longer to complete but there is no way to monitor it and know when it's done.
Reconnect the USB cable
Pull down the Notification Panel
Select USB Connection and change it to MTP. Note there may NOT be an icon in the status bar.

MTP connections use the External Storage app, and by association the Media Storage app, for USB access to the device. There is no direct access or "mass storage mode" anymore, it is all software emulated.
If this fails, a full factory reset is usually required. In rare instances, this does not fix it most models have firmware available on XDA, but that step likely is beyond the scope of this question.
Of course, all this depends on a working USB port on the phone and a good cable... although it is extremely unlikely, it is possible for the USB port in the phone to be defective.


Recovering pictures from Internal storgae

Android Data Recovery can recover your deleted/formatted files from Android devices without taking out the SD card or CF card inside the Android phone or tablet. This program has a strong ability that not only can recover photos and videos, but also can recover contacts, text messages, and other data. You can download it from the play store.
I'm not sure if you've used backup photo apps but generally speaking Google photos automatically backup your photos. Try sending a text message and adding a photo as an attachment  it'll bring up a menu and it might show the places that your photos are saved to, you can also try downloading a file manager like ES and look for them there. Hope this helps.


Try to install TWRP recovery and full (or partial) backup can be done to additional SD card plugged to Your phone.


I have been using PicSay's free version and been happy with it.  I'll probably upgrade to the full version which has the ability to sharpen, but just haven't really had the need yet so I've been putting it off.  I'll report back if I do chip down.

Another alternative would be to use Pixlr's web based editor: http://pixlr.com/editor

Provided you have flash installed you can use their browser based editor that does have an "Unsharp Mask" filter.


Is there a way to create an icon on the home screen that will launch one of these scripts?

There is another way (other than this one) if you happen to use Terminal Emulator for Android app. It allows a widget which can be used to execute a script.

Install that app, choose Term Shortcut widget in your current launcher.
Corresponding to Arguments enter:

sh <FILEPATH>

In my case, the query was:

sh  /sdcard/airdroid/dd.sh

As for the root access, you can either provide su access from inside the script and use the aforesaid command for execution, or do:

su -c "sh  /sdcard/airdroid/dd.sh"

Choice is yours!

Choose icon or shortcut label as per your needs, tap OK and an icon would be placed on the home screen.
Tap the icon, the Terminal Emulator app window would open and the script would execute, just like in Desktop GNU/Linux.

We're good to go!


Galaxy Note3 is not recognized by Odin ("SeAndroid not enforcing: set Kernel")

i think you are mixing up things

Odin requires your device to be booted in download mode, not recovery mode. if you are in twrp you must leave revovery mode, you can reboot into bootloader from twrp menu. other method to boot into download mode is button combination Volume Down + Home + Power. then select Continue with Volume Up

SeAndroid not enforcing is just a info message which tells you everything is all right. for full access to partitions TWRP requires kernel which allow setting selinux permissive. if SeAndroid is enforcing it would prevent TWRP from working properly

side note: whatever you want to flash from Odin, you could do from twrp command line, too. twrp has full access to all partitions and skilled user can raw write partition images with adb push or dd


Mounting SD card as USB drive on Windows PC (Marshmallow)

As you said, it's possible only if your device is rooted..
Google no longer supports USB Mass Storage Mode due to several reasons, since JellyBean.

However, there are softwares for PC that virtually shows & provides access to the device (connected in MTP mode) as a Removable Storage USB Drive, like for example, MTPdrive (as @beeshyams commented); no root access required in device. But it's just a virtual round-about connection, hence it'll be slower than UMS & even MTP mode..

Or try WiFi USB Disk - Smart Disk, which also virtually shows your device as a USB Drive (through WiFi). Or you can do that yourself using file servers by mapping a network drive to your device.

To get your device's memory card actually mounted as a real UMS device, the only way is to root your device..

There are many root apps that would help you enable UMS. Some of them are:

Multi Mount SD-Card ( Lite | Pro )
USB Mass Storage Enabler (an app created by me)
USB Sharer ( Free | Full )
SD Card as USB Drive ( Free )

Note: Some apps require you to disable SELinux (that is, setting SELinux mode to 'Permissive' by setenforce 0 command)


How do you delete Google Calendar goals?

Same Calendar Version as yours ( update released on 15/08/2016). Moto X Play 6.0.1

I created goals using goals option of app and am able to choose and delete. Screenshots below

First one shows goals for today and tomorrow
On pressing one of them it appears as in second one
Third one shows the Delete option on pressing the overflow (3 button) menu
Last one shows the options you are looking for


As your device is rooted, and you even have Xposed running on it, you have a pool of choices – e.g. Obb on SD would probably be your first choice, as it exactly matches your requirements. It lets you move all or only selected OBB to the external SD card. There are several alternatives; be welcome to check my list of helpers with storage media for that.


Unknown apps/processes with number only are shown in the battery screen

Possibly right answer:

It's a sandboxed process from a removed app.

For such a number over 99000, it is the Unix UID for an isolated sandbox process (u0_i70).

In Android's UID system, called "AID". Android allocated 1000 special UIDs for isolated sanbox processes, 99000-99999. Some apps use that for security reasons, like Chrome (Incognito mode).


How to "extract" files from an Android app?

Basically, APK files are ZIP archives. You can open, view and edit them, however, after editing, you need to re-signed it to be able to install. You can download APK files directly on websites like APKPure, APKMirror,... If you want to extract the APK file of the app you downloaded on the Google Play Store, you can use ADB (require computer) or ES File Explorer (directly on the phone and does not need ROOT).


Backup your data and factory reset your device. If problem is intact, its firmware issue. Fixing it isn't easier than flashing new ROM.

The best way to work around: Disconnect Mobile Data by renaming APN. No need to factory reset or to flash new ROM. You don't need to rename APN manually. Install Widgetsoid and use its mobile data toggle widget. In settings, make sure toggle method is APN renaming. Done!


Can't boot into recovery or downloading mode on galaxy player. Is it hardbricked?

It's probably not hardbricked, only softbricked. The phone with triangle and exclamation mark is telling that you didn't flash properly. In that case it should still allow you to boot into download mode. Remove battery, put it back in and hold the appropriate buttons to boot into download mode and then reflash rom


How is it possible to listen to FM radio while a phone is on airplane mode?

Air plane mode disables all transmitters as these are creating the strongest radio waves that exit your Smartphone.

For some services like mobile network, WiFi and Bluetooth disabling only the transmitter without also disabling the receiver does not make sense, therefore both services are completely disabled.

The fm receiver however only receives the fm frequency and therefore does not have to be disabled in air plane mode. The same holds for GPS.

Note: Even disabling all explicit transmitters of a Smartphone some implicit transmitters of radio waves may still be active, e.g. the CPU and other electronic components can emit radio waves. However those radio waves are a lot weaker than e.g. a WiFi signal.


Does deleting a gmail account from one device erase all the activity for that device in the my activity section.

No, removing a Google account from a phone doesn't affect Chrome history, Google search history, or app installation history from the time before you removed the account. You can clear all the activity from the account, but you can't only clear the activity that was from a particular phone.

It's like if you use Facebook on a friend's computer and then log out of Facebook from that computer. Logging out doesn't remove the Facebook posts you made while you were logged in. You can't automatically delete all the posts made from that one computer, because they're associated with the account, not the computer you used.


How can I boot to a specific partition with ADB?

Using bootctl
Though it requires adb root, one method to do this would be to use bootctl if available.
#> bootctl set-active-boot-slot SLOT
#> reboot

Note: SLOT is a number, you can find out the labels by looping through them and calling get-suffix for example this little shell script,
for slot in $(seq 0 $(expr $(bootctl get-number-slots) - 1)); do
  echo $slot: $(bootctl get-suffix $slot);
done;

Which will return the mapping,
0: _a
1: _b

See also: How can I tell whether I am booted into the A or B partition?


Is there any camera application that can save photos on internal storage?

On the home screen, go to System Settings/Storage and change Default write disk to phone storage instead of SD Card.  This will solve your problem!


LTE Bands for European Galaxy S7 (SM-G935F) while in the US

Starting from Note 5, Samsung has blessed their flagships with near-iPhone level of international cellular capabilities, as shown in the specs you've read. VoLTE and Wi-Fi calling might take a hit, but as long as AT&T is willing to offer and activate a new SIM for you, you should be fine using LTE itself.


Issue with the Apps that are installed on SD Card after reinserting the SD Card

Try rebooting the phone after re-inserting the SD Card.

Some older launchers (e.g. Eclair stock) simply don't refresh their app drawer when you re-insert the SD Card, even though the apps are re-mounted. You can check that the apps are indeed back by going to Menu -> Settings -> Applications -> Manage applications and seeing if the "missing" apps are listed there. If so, a reboot will fix it.

Alternatively, you can simply restart the Launcher app by going to Menu -> Settings -> Applications -> Manage applications then scrolling down to "Launcher" and tapping on it, and then tapping on the "Force Close" button.  Now if you press the Home key, the Launcher will restart and should have all the apps back.


NOTE 10.1 (2012) HDMI not displaying correctly

I have fiddled around and found that altering the decode mode from HW to SW or System player in BSPlayer fixes the issue! This also works for MXPlayer too.

This results in the correct video ratio although it is not full width on a 1080p tv (just like my desktop) it is at least not stretched. I still don't get why Google Play Movies can play its native videos full width on my tv.

Queue a Google Play app to download later on wifi to save mobile data?

For an update to an existing app, you just have to enable that in Google play's settings. For a newly installed app, I don't think it is possible. You can block the  background data for Google play, but that's just a workaround and it has limitations like you won't be able to make in-app purchases when you are on mobile network.


newbie: how to get larger keys on lockscreen keyboard?

Considering that you responded in the comments that landscape-only is alright, I'd suggest Ultimate Rotation Control. Use its "Forced Auto" mode to rotate any apps to any direction you want - that of course includes the lock screen. After proper settings, it could seamlessly integrate with the built-in rotation switch too (basically you could toggle the built-in switch and the lockscreen will now obey).

On my devices, when I have a password set and lock screen rotated to landscape, tapping on the password textbox will show a full-screen editing interface with landscape keyboard, which should be good enough for your fingers.
