Did Google remove the "backup while on wifi" option from the Photos app?

OK, so I did some testing and have determined that although the wording on the Photos "Settings" screens has changed, it is still possible to back up your photos solely when the phone is connected to WiFi.

On the Settings-->Back up & sync screen, enabling "Back up & sync" means "WiFi ONLY" by default. Lower on the Settings screen, in the "Cellular data back up" section, enabling "Photos" means that you are allowing photos to back up when on your cellular network. Leaving this switch off will prevent cellular backup of photos, but by virtue of having "Back up & sync" enabled at the top of the screen, your photos will back up via WiFi.

See the screen shot below. I have drawn in red to emphasize the toggle switches mentioned in my answer.


You can press the power button or use program like Screen Off and Lock. The advantage of software lock is it will prevent wear and tear of your hardware button.


Alarm clocks aren't working on Android 6

When you say the little alarm status bar symbol, do you mean up the top left? If so, it sounds like that alarm app is running as a Service rather than registering with the system's AlarmManager.

When you swipe the app away from the multitasking view, you are killing the Service. More details

I have only a few suggestions:

Ensure the app cannot be optimised to save battery. Settings->Battery->Battery Optimisation (Overflow menu). Ensure app is displayed in Not optimised section.
Don't swipe the app to close it. This typically isn't needed on modern Android phones. Though really, I'd still not trust the alarm as the system can clean up apps whenever it needs to.
Use a different alarm app. I use Timely on Marshmallow and have never had a problem with it.


If I charge my mobile from different charger what happens?

No, it will not damage your phone. As long as it's a micro USB charger, it will be fine.

5.5V is fine, I've had success with 6 Volts from a homemade charger, and you won't meet voltages higher than 5.5V on a micro USB charger anyway. Extra Volts are dangerous, so it's good to be cautious but 5.5V will not do any harm.

The current rating (Amperes, A) does not count; if it's too low, the phone may charge slowly or not at all, but higher rated chargers will not do harm.


What Percentage of Android Devices Run on a 64-bit Architecture?

I have not yet been able to view recent statistics, but
according to this article published end of 2017:

  The ARMv8 instruction set architecture rolled out 64-bit hardware support in 2014, and now almost every new Android device can run 64-bit code (but only 40 percent of active devices)

From this ARM's blog post:

  Nearly 90 percent of today’s Android devices deploy a 64-bit capable version of the OS (version 5.0 and above).

Statistics on the percentage of OS used can be checked here and here.


"No emoji found" in Google Japanese Input

I found the answer 10 minutes after posting the question, that's silly.

The trick is, you must search in hiragana. Even if your locale is English (like in my case).

For instance, search for ねこ instead of cat or 猫:

Most users type the hiragana before getting the kanji anyway, so it kind of makes sense if you think about it afterwards.


Wileyfox Swift Mobile data not working after update to Nougat 7.1.1

Overall it looks like a issue related to the kernel. I would say it would be possible to fix this just by installing another version and/or install a custom kernel which very likely fix this issue if it is related to the kernel. While you are trying this I would also recommend contacting the developer and reporting this issue. Also try another Simcard slot if you can. I had a similar issue sometimes with my phone too but a reboot fixed the issue usually.


How to Override Google Play's Compatibility Check

I don't see a way to do so without massive system modifications (rooting and more) because the "compatibility check" is done on Google (server) side.

When using your phone with Google PlayStore your phone registers and identifies itself with a certain brand, name and version at Google.

Furthermore a list of available system libraries, device features and device characteristics (screen size and resolution, ..) is sent to Google.

Last but not least the country and mobile network operator is also sent as some apps country and/or MNO restricted.

If you now search for an app or try to access one specific app Google compares the app specification with your device spec and then decides if you get access to that app or not.

Note that the app developer can (optionally) manually select the devices the app is compatible with. Google has a large list of each and every Google Android device on the market.

Hence if you want to bypass the compatibility check your phone would have to pretend to be a different device and model that it actually is. This can get complicated as Google has a list of every Google Android device with every firmware version ever available. Hence forging the data to pretend to be a different phone model can be pretty complicated as Google exactly knows how what data to be expected.

Furthermore there is the problem that sometimes you don't know why the compatibility check fails. Some years ago Google was "so friendly" to exactly send back to the device why your device is incompatible (e.g screen too small, system library xyz not present, feature xyz missing). But that changed at some point and now you only get back the info "hardware incompatible".


How to install python on my Android GT-P7510?

You can try SL4A.
Which can help you to run python on Android. https://github.com/kuri65536/sl4a/releases/download/6.1.1/sl4a-r6.1.1-arm-debug.apk


For those who may encounter this in the future (trying to rip this tone perhaps?)
apparently, this tone is not saved locally as a file but rather appears to be generated on the fly by android:


Tool to find duplicate files and hardlink them

SD Maid can help you find duplicates. You need to buy the pro version to unlock all features though (in the case of duplicates, deleting them from the app).


CWM is the shortform of ClockWorkMod.  ROMManager, CWM recovery, Tether etc are their products.  CWM Recovery and ROMManager are tools which enables you to backup your current ROM, install custom ROMs etc.
If you are interested in knowing more about CWM, see this page.  For rooting you do not need CWM. In fact for installing CWM you need to be rooted.
For anyone who plays with ROMs, tweaking and testing, CWM Recovery or some thing equivalent to it is mandatory and would save your neck several times.
Also, you could specify which part you are not clear with.  It will help to get better answers. :)


How do I install Cyanogenmod 11 on a Samsung Galaxy Tab 2 (GT-P5113)?

Update

Previously it wasn't possible.

  In short, the previously used set_perms method was deprecated and replaced by set_metadata. Unfortunately, most of available recoveries didn’t allow users to flash these packages properly, and this has resulted in the following error message: set_metadata_recursive: some changes failed

But now all major recoveries support set_metadata_recursive. Just use a version of TWRP newer than 2.7.0

What I did was boot into Download Mode:

Shut down the tablet.
Unplug the USB.
Hold Volume Up and Power.
Let go of both after it boots and you see it is in Download Mode.
Plug in USB.

Flash it into the RECOVERY partition,

heimdall flash --RECOVERY twrp-3.1.1-0-whatever.img --no-reboot

Now when you boot into Recovery Mode and you're in TWRP you'll see the option to flash the CM11 .zip, or adb sideload it, which is what I did.


Where to download official Wiko Jerry drivers for ADB/USB connection?

You just need Mediatek drivers for any phone powered by an MTK chip. Since [all] Wiko devices are powered by Mediatek chips, you can use drivers for Alcatel MTK, or ZTE, etc.
Go here to download the firmware which contains the flashtool, drivers and instructions.

or here to get the Wiko drivers (VCOM and CDC)


Can't mount first-gen Kindle Fire in TWRP

Ultimately I plugged the Kindle into my Macbook instead of my Ubuntu machine, and it mounted it just fine. No idea what the issue is with my desktop - all other devices on the hub work fine, switching ports changed nothing, etc etc.

If your device won't mount, try it with a different computer. For some reason.


How to search for Android apps without ads?

There's the Playsearch website which allows you that without having to install anything beforehand:

Playsearch website, your criteria marked (click image for larger variant)

In addition to what you asked for, you even can specify how long ago the last update should be at maximum, what size the app should have, what Android version it should support, how well it ranks (stars) – and how wide-spread (number of installs) it should at least be.


Is it using a custom ROM or a modified stock ROM?

Flashing DjeMBeY's pre-rooted S4 ROMs has issues with Wi-Fi, esp. for those higher than MGA. They have a Wi-Fi fix, but I still encountered issues (e.g. intermittent mobile data, loss of audio / sound). So, I downgraded back to MGA.

Hopefully reading the thread in XDA might give you some ideas. Do share your answer if you find something useful, or a solution.


Screen brightness too high on auto mode when in the dark room

Short answer: no.

Auto brightness is usually a battery waster.

I like to use the Brightness widget, it will let you turn on/off auto-brightness or with one touch adjust the brightness to one of several presets.


Need to give away Milestone that's rooted, what happens if I do Factory Data Reset?

Depending on the device (and root method), the su binary (which gives your device root) is usually located in /system/xbin/ or /system/bin/ directory, while the Superuser.apk (which acts as a gate keeper, presenting you with a dialog when apps request root permissions) is always in /system/app/.  The /system partition does not get cleared by the Factory Reset process, so it's safe to perform while still retaining root.


Why does an app have a different icon on my actual phone vs on Bluestacks and its Desktop Icon?

There are two main reasons why an app shows a different icon:

Some apps provide different APK files for different platforms. Different APK files means that of course not only the code but also resources like images can be different. However it seems like the app you mention is only available in one version.
An app contains images and icons for different device resolutions. Therefore if the display pixel density (measured in dots per inch - dpi) of your actual phone and the Bluestacks VM differs you may see different images. How much they differ depends on what images has been created by the app developer.


Note that @dan-brown seems to be right about the root cause of the issue - it looks like a corrupt install after flashing a new TWRP.

However there is a non-destructive fix, as documented here.

Boot into recovery
Navigate to /data/system
Delete the following files:

password.key
pattern.key
locksettings.db
locksettings.db-shm
locksettings.db-wal

Reboot


Can't start clockwork recovery image lately

Try flashing the Recovery image manually via fastboot, as described in this guide:

  Download the latest version of the ClockworkMod Recovery from here.
  Place the ClockworkMod Recovery Image in the same folder as fastboot (the /tools folder with the Android SDK folder).
  Power the Nexus S down, and hold Volume Up & the Power button until booted into the bootloader. You should see a white screen with
  three skating androids.
  Connect the Nexus S to the computer via USB. On the computer, open terminal and run: fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img

  The ClockworkMod Recovery should now be installed on the Nexus S.


Summary: the more cores you use the more battery you consume so CPU hotplugging turns off the other cores, and the others do the work which makes them at 100% CPU usage, which also give the best performance and the most balanced one.

It's CPU hotplug It turns on and off the cores when needed or not.

It's running 100% CPU usage because it's like this. Imagine, there's a 4 car, and let's assume the drivers are the cores. You have four lanes and 4 cars of course. Each one of them will take 100 pizzas. You can let one  core to do all the work and that's what hot plugging do. Knowing that a car with 50 pizzas consumes a lot less fuel than a car with 100 pizzas you can now see how we can have the same performance and save on fuel: load two cars with 50 pizzas and let them accelerate as quickly as possible to the destination (performance governor). They will get there as quickly as one car with 100 pizzas (same performance), but burn less fuel (battery saving).

If you want to make your phone run at 8 cores then you need to install a custom kernel, use an other CPU governor, use a custom CPU hotplugging, or without installing a custom kernel use an interactive governor, then tweak its parameters.
You can search on XDA for Advance Interactive governor tweaks.


When should I get suspicious over permission requests and when should I safely install an app?

Well, there's a lot of questions in one. Let's handle a few:

If your concern is major applications, such as Facebook, Twitter, etc., from major publishers and services, then as long as you're downloading updates from the Play Store, there's no reason to assume you're downloading a possible malicious application. The apps are all digitally signed and scanned by Google. While malware HAS gotten onto the Play Store, it doesn't get on there as updates to major, legitimate apps. It ends up on there as its own unique app from shady publishers, or updates to apps that got sold to a new publisher, etc. If a major app like Twitter or Facebook wants a new permission, you can feel confident it's for a feature and not malicious.

What that doesn't tell you is whether or not you're comfortable feeling paranoid about how that major publisher intends to use that permission. Some people strongly distrust Facebook, and are unwilling to hand those sorts of permissions to them, even though the app isn't strictly malicious, as it's the company they have an issue with. That's more of a personal judgment call than anything else.

The other priority is to familiarize yourself with what the permissions actually mean (here's a good place to do that from Google), and get a basic understanding of how apps actually function. Some sound scary until you understand why they're necessary. An example was someone I found upset over a keyboard app requiring permission to monitor everything they type, oblivious to the fact that without that permission, it couldn't function as a keyboard. Understanding how apps need to communicate over the network, or be aware of incoming call status in order to pause a game, or being able to review contacts in order to try to suggest new friends based on people you know, or needing access to the camera because they can take photo notes or do video chat, etc., will help you parse which permissions fit within the mission of the app and which ones seem like a stretch to possible data-mining. Google's descriptions tend to focus on the worst-possible scenarios because they have to allow for them. But dialing back and recognizing that, yes, this permission does allow for scenario Z, but it's also the only way they can do scenario A, which is right in line with the goal of the app, will help you figure out when you're being a little paranoid.

How to root Samsung Galaxy S5 for AT&T with Lollipop

Here's an XDA instructions to root Samsung S5 G900A (AT&T):
https://forum.xda-developers.com/att-galaxy-s5/general/guide-merry-christmas-heres-t3516196

That's the only solution I found working!

1) Save these to the Samsung SD card:

SuperSU APK
Towelroot APK
Flashfire APK
pre-rooted OF3 firmware

2) Now on your Desktop PC, download this firmware:
COMBINATION_ATT_FA44_G900AUCU4AOF1_ATT4AOF1.zip

3) Install the "COMBINATION" firmware using Samsung Odin (you'll have to boot your device by pressing Volume Down + Home + Power ON)
This will wipe ALL data on the device! Backup your stuff before proceeding.

4) After this new firmware installed and loaded, open Android file manager, go to the SD card, and install those APKs: Flashfire, SuperSU, and TowelRoot.

5) Connect to the internet (Wifi), and then go into "Settings > Date and Time" and tick the "Automatic date and time" box. This is mandatory for TowelRoot to work.

6) Run TowelRoot app -> "make it ra1n". Now you'll have the root binaries installed.

7) Run SuperSU app -> "new user" -> update SU binaries -> reboot.

8) Run FlashFire app -> grant it root access -> flash ZIP -> choose the OF3 firmware from SD -> set options to Mount /system read/write -> Hit "flash".

You're done! Enjoy Samsung S5 with Lollipop unlocked!


The bravia engine would need to be included in the new ROM you are installing. It is a software screen enhancement.

http://allenramos.blogspot.ie/2013/05/enhance-your-android-phones-display-w.html?m=1

  The Sony Mobile BRAVIA Engine 3 is a video enhancement program for Sony phones. It uses filters and algorithms to create a clearer and more contrasted picture and an overall smoother experience.

Alternatively there are often flashable zip file mods for the bravia engine for different devices.


See the section on Automatic Aggregation of Contact Data in the Using the Contacts API from the technical resources on the Android Developers site.

As the article explains:

  When a raw contact is added or modified, the system looks for matching (overlapping) raw contacts with which to aggregate it.  It may not find any matching raw contacts, in which case it will create an aggregate contact that contains just the original raw contact.  If it finds a single match, it creates a new contact that contains the two raw contacts.  And it may even find multiple similar raw contacts, in which case it chooses the closest match.

  Two raw contacts are considered to be a match if at least one of these conditions is met:

  They have matching names.
  Their names consist of the same words but in different order (for example, "Bob Parr" and "Parr, Bob")
  One of them has a common short name for the other (for example, "Bob Parr" and "Robert Parr")
  One of them has just a first or last name and it matches the other raw contact. This rule is less reliable, so it only applies if the two raw contacts are also sharing some other data like a phone number, an email address or a nickname (for example, Helen ["elastigirl"] = Helen Parr ["elastigirl"])
  At least one of the two raw contacts is missing the name altogether and they are sharing a phone number, an email address or a nickname (for example, Bob Parr [incredible@android.com] = incredible@android.com).

  When comparing names, the system ignores upper/lower case differences (Bob=BOB=bob) and diacritical marks (Hélène=Helene). When comparing two phone numbers the system ignores special characters such as "*", "#", "(", ")", and whitespace. Also if the only difference between two numbers is that one has a country code and the other does not, then the system considers those to be a match (except for numbers in the Japan country code)

  Automatic aggregation is not permanent; any change of a constituent raw contact may create a new aggregate or break up an existing one.

The article then goes on to explain the various modes that an application can assign to the raw contacts that it creates.  Depending on the mode, the system will either:

Automatically aggregate the contact as similarities are found with other contacts.  Where similarities no longer exist, these aggregations will be removed.
Never aggregate the contact with any other.
Perform no further aggregation on a contact, even if that contact changes such that it would be taken out of an aggregate group.

Aside from this automatic aggregation, applications are also allowed to manually set up aggregate contacts.  In these cases, the algorithm depends on the application.

Finally, you may manually join contacts in the People app by editing one of a pair of contacts, and selecting Join from the overflow menu.


That's not possible – as in Bootloader mode, there's no real OS loaded yet (see XDA Wiki and AddictiveTips). Quoting from AddictiveTips:

In literal terms, bootloader is code that is executed before any Operating System starts to run. The concept of bootloaders is universal to virtually all Operating systems that inculcates operating systems on your PC, laptop, smartphones, and other such devices. Bootloaders basically package the instructions to boot operating system kernel […]
Every Android phone has a bootloader that instructs the operating system kernel to boot normally.

(emphasis mine)
As there isn't any OS running yet in this mode (especially no Android), there's no ADB that can be run. That applies all the same to "Download mode" with Samsung devices, or HBoot with HTC (just different names for the same thing).


How can I view a certificate's details in Chrome on Android?

Click on Green Padlock symbol in navigation bar next to URL, click on Details and click on Certificate Information to view the Connection details.

(Click image to enlarge)

You can also view DigiCert SHA2 CA, High Assurance CA in the drop-down under certificate viewer.

EDIT:

For HTTPS websites without a Green padlock, Chrome will give an error saying
Your connection is not private if you're visiting the site for the first time and you can click on the Red Padlock -> Details -> Certificate Information.

(Click image to enlarge)

Also, if you're not getting the Red padlock when you visit the page, that's because you've clicked on Proceeed to Webiste, I understand the risks.

To get back that Red padlock you have to Clear cookies. To do that, Chrome → Settings → Privacy → Clear Browsing data → Clear Cookies and site data.

How do I enable Google Now on my Galaxy Note 2 (NT-7100)?

You must be running at least Android 4.1 to use Google Now - please ensure this is true.

If you are running at least Android 4.1, then ensure you have the latest Google Voice Search update from the Google Play Store - be aware that it is listed twice (at least on my old device).


Charging speeds between USB C/USB C and USB A/USB C

Your device comes with USB Type C which is equipped to handle higher power for charging and hence that is recommended over using the USB C to A conversion

USB 3.1 – Type-C Connector

  ....Rather than using four-pins as in the classic type-A and type-B, the type-C connector has 24 pins and is reversible, meaning it can be plugged in either way. It supports 900mA and, on command, delivers 1.5A and 3.0A over a 5V power bus while streaming data. This results in 7.5 and 15 watt power consumption respectively, as opposed to 2.5W using the original USB (current times voltage = wattage)

Also see a decent comparison of  Type C Charging


How to check if an available update will take up more storage or less than the one currently installed version?

Current App's Usage:

If you mean storage, there's a handy program on market called Disk Usage. It will display the current size of all installed applications, as well as how much space each's data takes up.
I have a feeling you may mean RAM usage, which is a different animal indeed. To get the amount of RAM a program is currently using, see the Apps section of the Settings.  The Running tab shows the relevant details.

New Update's or Non-Installed App Usage:

Most of these details cannot really be determined before installing an app or an update, unless the developer is kind enough to include these details in the applications's description or the What's New section.  The closest you can get is the actual size of the application, which does show up in the application description.  I guess you could use a combination of what you can learn from Disk Usage on the current version's size and correlate that to what shows up in Google Play for the current version.

Details like RAM usage are difficult to determine as they depend on a lot of factors:

Which resources are loaded on your particular device configuration (e.g. high or low res images and icons).
How you use the app (e.g. if you have a browser and load 100 tabs, the program will use more RAM).
The quality of the app.  The program may inadvertently waste memory due to a bug only you experience.  It would be difficult to predict things like this.

As for app storage, this really depends on whether the app developer chooses to change the way it stores data.

Hopefully this answers your question.


How do I get the hidden achievement in the new Google Play Games app?

From the main listing of games in the Google Play Games app, you need to swipe the old Konami Code:

↑ Up, ↑ Up, ↓ Down, ↓ Down, ← Left, → Right, ← Left, → Right (and then when the retro button grid pops up), B, A, ▶ Start.

You should then see an achievement notification pop up.

Here's a YouTube video that demonstrates how to do this.

How to make a key act as acute and apostrophe? dead keys problem

Ok, this is not the answer, this is some kind of "workaround" that I don't like. It works but makes me memorize another super key combo.

# In the keycharmap I puted this:

# this is the default for this key
key GRAVE {
    label:                              '`'
    base:                               '`'
    shift:                              '~'
    alt:                                '\u0300'
    alt+shift:                          '\u0303'
}

key APOSTROPHE {
    label:                              '\''
    base:                               '\''
    shift:                              '"'
    alt:                                '\u0301'
    alt+shift:                          '\u0308'
}

And with that settings I get this results:

Alt+APOSTROPHE A = á
Alt+APOSTROPHE O = ó
Alt+APOSTROPHE Shift+A = Á
Alt+APOSTROPHE Alt+APOSTROPHE = ´ (lonely acute)
APOSTROPHE = '
Alt+Shift+APOSTROPHE A = ä
Alt+Shift+APOSTROPHE Shift+A = Ä
Alt+Shift+APOSTROPHE Alt+Shift+APOSTROPHE = ¨ (umlaut)
Shift+APOSTROPHE = "

Using Alt+Shift feels unnatural and I'd like to get the same behavior that I've got on my PC, but for now this works.

Why Whatsapp images and videos are not showing in my gallery?

I believe the trick here is to somehow get the media scan to run again. I would normally expect a reboot to take care of this, but perhaps a more explicit instruction will work.

As per this answer, I'd suggest executing the following ADB command:

am broadcast -a android.intent.action.MEDIA_MOUNTED -d file:///mnt/sdcard

Also, be sure to check that .nomedia doesn't occur in any of the folders (or subfolders) of Whatsapp's media directories.


How to restore files from a WhatsApp group deleted by administrator

If you were a group participant, then the group should still be in your phone. Although it would show that you are not a member, you should start still be able to access the old chats and media.

If you cannot find the group, then:

If you have downloaded the files, then you should be in your WhatsApp folder:

Internal storage/WhatsApp/Media

WhatsApp organizes media in different folders based on the type i.e. Audio, Video, Images, Documents.

You should be able to find the group media in one of these folders. However, this is a combined collection of all the media and you'll have to dig your way through it to find what you're looking for. There's no way to filter this media by group name.


How to save all contacts to Google with a broken SD card?

According to the GMail help pages, you should be able to easily export your contacts using a web browser:

Sign in to Gmail.
Click Gmail at the top-left corner of your Gmail page, then choose Contacts.
From the More drop-down menu, select Export....
Choose whether to export all contacts or only one group.
Select the format in which you'd like to export your contacts' information. Please note, some of these formats can lose some contact information.

To transfer contacts between Google accounts, use the Google CSV format. This is the recommended way to back up your Google Contacts.
To transfer contacts to Outlook, Yahoo! Mail, Hotmail, or various other apps, use the Outlook CSV format.
To transfer contacts to Apple Address Book, use the vCard format.

Click Export.
Choose Save to Disk then click OK.
Select a location to save your file, and click OK.

This (and some other details) are also described in a post titled How to Create Mail Merge in Gmail Contacts.

Now you write you have some contacts which are not synchronized with your Google account, but stored on your SIM card. Of course, you first need to "convert" them to "Google contacts", which is described in How do I import all contacts from a SIM-card to an Android phone?:

open the contacts app
press the "menu" key
navigate to Import/Export → Import from SIM card
click "Select All" (or manually select the contacts you wish to import)
when asked where to copy the contacts to, select the appropriate option

This procedure can also be found in a tutorial at AndroidAdvices, together with some screenshots to visualise the process.

Your broken SD card should not matter here, as it isn't involved anywhere in the process.

I recommend you to flash the stock firmware on your device.

As you said you didn't know where to download firmwares for Samsung devices; I'll give you some information.

Personally I always use a site called Sammobile. They host every firmware made by Samsung. The firmwares are 100% stock and won't trigger Knox. You will need to register an account on their website, but it's free.

You can download the firmware for your device here. The firmware can be flashed by using a Windows application called Odin (download link in the guide below).

When the firmware is downloaded, flash it on your phone. Here are the steps:

Extract the firmware
Download Odin 3.11.1.
Extract the Odin zip file.
Open Odin.
Reboot your phone to download mode by holding the home, power and volume down buttons. Release only the power button when at the Samsung logo, and release all of them when you see a green Android robot. Then press volume up to accept the warning and you'll see DOWNLOADING.
Connect the phone to your PC, Odin should now see your device.
Add the firmware file to AP/PDA. (The "not responding" is normal, just wait).
Make sure re-partition is not checked.
Click the start button. The flashing can take some time.

  Note: The firmware will not factory reset your phone, so if your phone is stuck booting, don't worry. Just boot to the recovery mode, do a factory reset and reboot the device.


Add a shortcut to a different home screen?

That might work with specific "Launchers" which support a direct "go to screen X" (not all launchers do). A launcher that does support this is Apex Launcher, even in its free version:

Screenshot of Apex actions and shortcut edit (click images for larger variants)

On the homescreen, press an empty space as if to add a widget/shortcut. From the popup, select "Apex Actions" ("Apex-Aktionen" in the screenshot). Scroll to the end of the list (red box in the screenshot), and you find a shortcut to each of your homescreens.

Note that after having selected the screen you want to link to (say, "Screen 1"), the link will be immediately created as shown and with the name "Screen 1" – which probably is not exactly what you had in mind. But we're not done yet: Long-tap (tap-and-hold) the new icon on your homescreen, until a context menu appears. From that, select "edit" – and you should see something similar to the second screenshot. Here you not only can change the description shown below the icon, but even the icon itself – to e.g. replace it by a coin for your "financial screen". You can chose from "standard symbols" included, and also from your own pictures.

Enjoy :)


Is there any custom ROM that includes a feature to permanently kill a process?

Cyanogenmod ROMs has a feature that by LONG pressing the BACK button you can kill the running process.


Is there a RAM test for Android devices?

This tests RAM, storage and well many other device features: Phone Check (and Test)


Step by step guide to build androidx86 with virtual box guest os integrations

To use GPU acceleration for android x86 vm it's easier if you use qemu.Check this out(the method i used and this video are not fully same.i used the latest version)
Linux exclusive-Feel free to comment your questions

Install the following build dependencies(no need to build for arch linux read below) usingsudo apt install -y build-essential libepoxy-dev libdrm-dev libgbm-dev libx11-dev libvirglrenderer-dev libpulse-dev libsdl2-dev libgtk-3-dev libsdl1.2-dev ninja-build

cd into directory you want to download and build qemu(if you use arch linux you don't have to build qemu.just use the package in official repository.also it is not necessary to add your user to kvm group.it just works.)
Download latest qemu sources using git clone https://git.qemu.org/git/qemu.git
run cd qemu
run ./configure --enable-sdl --enable-opengl --enable-virglrenderer --enable-system --enable-modules --audio-drv-list=pa --target-list=x86_64-softmmu --enable-kvm --enable-gtk
run make
run sudo adduser yourusername kvm
run sudo chmod 666 /dev/kvm
run sudo touch /lib/udev/rules.d/99-kvm.rules
add line KERNEL=="kvm", GROUP="kvm", MODE="0666" to 99-kvm.rules
you can do that by sudo gedit /lib/udev/rules.d/99-kvm.rules and pasting the line then saving.
run sudo apt install qemu-utils
cd to the directory where you want create the virtual hard disk.
qemu-img create -f qcow2 Android.img 10G
10G refers to size of hard disk drive,in this case 10 Gigabytes.
Download androidx89.(latest kernel version performed better for me or was it just a placebo?)
cd to directory were u git cloned qemu
cd to directory qemu/build/x86_64-softmmu/ ie cd qemu/build/x86_64-softmmu/
run

qemu-system-x86_64 -boot d \
    -enable-kvm \
    -smp 2 \
    -cdrom "/path/to/android/iso" \
    -name linuz \
    -device virtio-vga,virgl=on,xres=1280,yres=720 \
    -cpu host \
    -device AC97 \
    -m 2048 \
    -display sdl,gl=on \
    -drive file=/path/to/android/Android.iso,if=virtio \
    -object rng-random,id=rng0,filename=/dev/urandom \
    -device virtio-rng-pci,rng=rng0 \
    -device virtio-keyboard \
    -boot menu=off \
    -device virtio-tablet \
    -machine type=q35 \
    -serial mon:stdio \
    -net nic -net user,hostfwd=tcp::4444-:5555

smp refers to number of cpu cores given to the virtual machine. -m refers to ram allocated.in this case 2048 megabytes.you can use -display gtk,gl=on also but display gtk does not work nvidia proprietary drivers for some reason.
Use arrow keys to navigate and enter to select.do as follows
Select Installation

Select create/modify partition

dont use gpt

Select new

select primary

press enter

select write and type yes .then select quit

select the partition we just created

select ext4

select yes to format

select yes to install grub

select yes to make /system read write (recommended)

Once all operations are over u can boot into android.
To boot directly to hard disk use

qemu-system-x86_64 -boot c \
    -enable-kvm \
    -smp 2 \
    -name linuz \
    -device virtio-vga,virgl=on,xres=1280,yres=720 \
    -cpu host \
    -device AC97 \
    -m 2048 \
    -display sdl,gl=on \
    -drive file=/path/to/android/Android.iso,if=virtio \
    -object rng-random,id=rng0,filename=/dev/urandom \
    -device virtio-rng-pci,rng=rng0 \
    -device virtio-keyboard \
    -boot menu=off \
    -device virtio-tablet \
    -machine type=q35 \
    -serial mon:stdio \
    -net nic -net user,hostfwd=tcp::4444-:5555

to use adb use adb connect localhost:4444

instructions to manually install native bridge

Download this file(http://dl.android-x86.org/houdini.php?v=9_y) in your vm.9 refers to android version if you have a previous version change it accordingly.or you can check it here

change the name of the file according to the version of android in my case houdini9_y.sfs.move that file to system/etc/ it can be done using terminal or root browser.

using terminal type mv /sdcard/Download/houdini9_y.sfs /system/etc if you are not comfortable with this method use a root browser app.

now got to terminal emulator type su (if you get a prompt asking weather to give superuser access say yes forever)
then type system/bin/enable_nativebridge
You might get some errors but they are safe to ignore i suppose.(i got two errors but arm translators worked)
Go to settings androidx86-options enable native bridge

Setting up tap networking
For better guest-host integrations i use a tap network.
sudo ip link add name br0 type bridge
sudo ip addr flush enp3s0
sudo ip link set enp3s0 master br0
sudo ip tuntap add mode tap name tap0 user yourusername
sudo ip link set tap0 master br0
sudo ip link set enp3s0 up
sudo ip link set tap0 up
sudo ip link set br0 up
sudo dhclient -v br0

replace enp3so with your network interface.use the following to command to launch the emulator
qemu-system-x86_64 -boot c \
    -enable-kvm \
    -smp 2 \
    -name linuz \
    -device virtio-vga,virgl=on,xres=1280,yres=720 \

    -drive file=/path/to/imgfile,if=virtio \
    -object rng-random,id=rng0,filename=/dev/urandom \
    -device virtio-rng-pci,rng=rng0 \
    -device virtio-keyboard \
    -boot menu=off \
    -device virtio-tablet \
    -machine type=q35 \
    -serial mon:stdio \
    -netdev tap,id=mynet0,ifname=tap0,script=no,downscript=no \
    -device virtio-net-pci,netdev=mynet0,mac=51:55:00:a1:11:32


Recovery mode is used mainly by carriers/manufacturers for replacing bad firmware that causes the phone to be otherwise unbootable.  Users can install signed update.zip packages (such as OTA updates) through it as well.  It does not run a full Linux kernel.  Custom recovery modes such as Clockworkmod exist also, which allow more complex things such as full backup and restore of the device software and data.
I'm not sure where recovery.img is unpacked to, but you can let the system handle that by using the following: adb shell flash_image recovery <path-to-recovery-image>, where the path is normally something like /sdcard/custom_recovery.img (wherever you put the image)


Android adware lets me opt out: is it safe?

You should absolutely not give them your information or install their app, only bad things can come of it.

You should check in Settings → Security (or Safety & Privacy) under Device Administrators and remove any that you don't want controlling your device (if present), and then see if you can figure out which app it is and then uninstall it under Applications (also in Settings).

If that doesn't work, try an anti-malware app from a respected company or follow the guide here.  In the worst case, you could also perform a factory reset (in the case of user app malware) or reflash the ROM (in the case of system app malware).


How can one change the battery saver to dark mode in Android 9 (Samsung Galaxy S9)?

The "Set by Battery Saver" option only means that the app's theme is determined if Battery Saver is enabled or not.

The Battery Saver itself does not have its own theme, but apps can query if the setting is enabled or not for customizing its behavior, including the theme.

On Google Drive (and some other Google apps, and possibly 3rd-party apps), this setting means that if Battery Saver is enabled, then use the theme that saves battery (e.g. dark theme).

To summarize:

Dark: always use the dark theme
Light: always use the light theme
Set by Battery Saver:

If Battery Saver is off: use the light theme
If Battery Saver is on: use the dark theme


When you are in the bootloader mode, the device no longer communicates via adb, if you want to now unlock your bootloader, you have to use fastboot.
Also, the Samsung Galaxy S4 (except for AT&T and Verizon versions) don't have a locked bootloader, all you have to do is flash a custom recovery via Odin, then you are all good to go.
TWRP is a good option for custom recoveries these days, you can go to their website and download the .tar version of their recovery, then put the .tar file into Odin's "AP" slot and hit "Start", your device should now be loaded with a custom recovery.
Here's the link to all the information required: https://forum.xda-developers.com/galaxy-s4/i9505-orig-develop/recovery-twrp-3-2-1-0-t3742880

Power Supply is actually a term with some actual, albeit generic, significance and meaning.

In handsets, the power supply is probably(I'm not an electrical engineer, or expert on device hardware) a component that regulates the power supplied to the device (keeping the voltage constant, for one thing), and manages the physical charging/discharging of the battery.

As far as what could have damaged it, it could be anything from dropping/shaking the device if there is a loose connection, to a short caused by water, to overheating. Unless you can find a connection that got loose, and the power supply is indeed fried, you'll need to get it repaired.

If you think there might have been any water damage, put the phone in rice for a day or three, it will dry out most liquid that may be in the device, and it might just work.

How to go change azerty to qwerty on huawei ascend y530

Have you tried this :{
If you go to settings->language and input

You will then see a section called keyboard and input methods, click the settings icon next to the keyboard you use, somewhere in the app that launches (depends on the keyboard) will be an option to use an qwerty keyboard, maybe keeping the same language.
}

Otherwise, try the following:
I would recommend downloading 'google keyboard' from the play store, as it has the option (under 'appearance and layouts->customised input styles') to have a dutch qwerty keyboard.


There are two ways Linux kernel modules are built: 1. as a part of kernel executable binary (compressed image) i.e. with CONFIG_*=y options at build time, or 2. as separate kernel object (.ko) files that can be loaded and unloaded with some conditions i.e. built with CONFIG_*=m options.
In second case the .ko files are placed on some standard location(s), usually /lib/modules/ on Linux and its equivalent on Android /system/lib/modules/ or /vendor/lib/modules/. These paths are hard-coded in binaries that load them e.g. insmod, modprobe.

On pre-Pie releases (1), by-default Android kernel is built without option CONFIG_MODULES=y, so there are no kernel modules built as .ko files which can be loaded or unloaded with insmod, modprobe or rmmod as is the case with standard Linux distros. Nor they are exposed through /proc/modules from where lsmod reads information. However each kernel component that can be built as a module has an entry in /sys/module.

Now those modules which are compiled and loaded as .ko file has a corresponding /sys/module/<module>/initstate file, others don't have. You can confirm this way if there are any loaded modules:

~$ ls /sys/module/*/initstate


Can't figure out how to play steaming video from a url with MoboPlayer

Four steps:

Open the MoboPlayer app;
If you don't see a small menu with icons at the bottom of your screen, tap "home" to bring that up, then tap "...";
From the white extra options board, scroll to see the far right side. There you will find "Streaming", tap to access;
Enter URL and enjoy the show.


Why is the Google Calendar website showing my calendar as a guest on events added from the phone?

I had the same problem. But it disappeared. I am not 100% sure why, but I suspect that either Android 4.0 (CM9)  fixed it, or the new separately released official Calendar app on Play Store.


Message app uninstalled after using viber?

"just solved the issue. apparently when an app is 'disabled' it ends up at the bottom of the HUGE list under application manager -> all apps

when you 'enable' the app, it re-joins it's place in the ranks alphabetically"

found this on another site,
for me it was in the tab "disabled apps"


If the app came with your phone, it's only licensed for the phone it came on. The phone manufacturer paid the software author for the right to use it on that phone only. If you want to use it on your new phone, you'll have to buy it this time.


Since you're rooted, you could also try the newest version of Google Talk. It isn't officially supported but I use it on my EVO just fine (I run CyanogenMod 7, though).

ooVoo has a desktop client and a mobile app, enabling mobile to PC video calls (supports the EVO, but haven't tried it myself).

There also appears to be a plugin for the Yahoo! Messenger app which enables video chat between mobiles or with the PC client. Again, I haven't tried this one myself, but it seems to be the least restrictive about what devices it supports.

Edit: It looks like there's a thread on XDA where people are talking about Skype with video on the EVO. Might be something helpful there.


Strange (unfamilar screen) on my Galaxy Tab?

Your device is in Download Mode. I don't have that device, but if the battery doesn't come out, you will probably need to use ADB and send an adb reboot to get it out of Download mode. If you don't know how to use ADB, then you can just let the battery die. I don't like that option though because the same image will be on the screen for an extended period of time.

Does the screen look like this:

To use ADB:

Download the USB Drivers from Samsung
Download the Android SDK
connect the device to your computer via USB cable
open a command prompt where the Android SDK was installed and change to the platform-tools directory. for example, my sdk is installed at c:\android-sdk so I run the following:

C:\android-sdk> cd platform-tools

then try to reboot with adb:

C:\android-sdk\platform-tools\> adb reboot

if that doesn't work try the following command:

C:\android-sdk\platform-tools\> fastboot reboot


The phone won't receive some text messages (Specially the verification codes from Google, Dropbox, Evernote, etc)

Do you have avg anti-virus installed on your device? If yes he might be the guy not letting through these short number messages


Playing an mp3 (from my phone) through my internet radio

AllShare is a Samsung specific product, which might not be available to devices of different brands. However, as it's basically a DLNA server/client app, you might want to take a look at some of the many alternatives available. A very good choice would be BubbleUPnP, which acts both as server and client (so you can stream from your device to other DLNA/UPnP clients as well as the other way around):

  BubbleUPnP is a full featured UPnP/DLNA Control Point, UPnP Media Renderer and UPnP Media Server. Play easily your music, videos and images on your phone and devices on your network (DLNA TVs, XBMC, WMP, ...), from your external UPnP Media Servers. Play your phone/tablet media to those devices.
  Browse and play your local phone/tablet and cloud media from other devices (PS3, ...).

  BubbleUPnP can also be used as a standalone music player, even without any network connection.


How can I set Tasker to change "Network Operator Settings"?

I don't believe there is a way tasker alone can do this.

The fastest way you'll be able to get this done is going to be using a plugin to allow you to recreate your interactions with android.

The AutoInput is popular choice to do this since the developer is responsive and just took over the Tasker app. Root isn't required for this to work but will most likely have it work more efficiently. Read the instructions provided to you by the app and it will tell you how to record your interactions.

You'll need to make two recordings, once for enabling these setting and once for disabling the settings. I'm not sure if this will work when your screen is off but having root should improve your chances.


connect android devices in ad-hoc mode without needing to net connection?

Ad-hoc is not natively supported by Android. But starting with Android 4.0 (Ice Cream Sandwich), a new feature called WiFi Direct was introduced:

  Wi-Fi Direct, previously known as Wi-Fi P2P, is a standard that allows Wi-Fi devices to connect to each other without the need for a wireless access point. This allows Wi-Fi Direct devices to directly transfer data between each other with greatly reduced setup.

(Source: Wikipedia)

  Support for Wi-Fi Direct lets users connect directly to nearby peer devices over Wi-Fi, for more reliable, higher-speed communication. No internet connection or tethering is needed. Through third-party apps, users can connect to compatible devices to take advantage of new features such as instant sharing of files, photos, or other media; streaming video or audio from another device; or connecting to compatible printers or other devices.

(Source: Android.Com)

To me, this looks like what you are asking for: directly connecting two Android devices via WiFi without the need of a "mediator".


How can I set a user profile password in Jelly Bean 4.2?

Each user account has its own lockscreen settings, so the easiest way to do this is to simply use a password lockscreen for each user. In fact, you can use entirely different lockscreen security for one user than you do for another (e.g. one could use a pattern, one a PIN, one a slide lock, etc).

To set this up, select a user and unlock the device, then go into Settings => Security =>Screen Lock and select the "Password" option (you could also use PIN or pattern, of course). Set the desired password, then lock the device. Repeat this process for each of the other user accounts to set up individualized passwords for each one.


Unable to access files in Samsung Galaxy Android 4.0

To start make sure your device is unplugged. Then run:

df -h

that will show you the list of currently mounted devices. Now plug in your device and run the same command again. You should see that there is a new device mounted. Now all you have to do is cd into that mount point to access the files. Here is my example output:

john-macbookpro:~ John$ df -h

If for some reason your device is not getting mounted, you should try to download ADB:

run ADB and it should try to manage your Android device.

adb start

I completely forgot about the adb_usb.ini file in the \USER_NAME\.android folder. Added 0x0C2E to the bottom, restarted ADB and all is good.

So, full instructions:

Get device hardware Ids from Device Manager in the form of USB\VID_1234&PID_5678&MI_90

ENABLE DRIVER:

Open file \android-sdks\extras\google\usb_driver\android_winusb.inf

Add

;Device Name
%SingleAdbInterface%        = USB_Install, USB\VID_1234&PID_5678
%CompositeAdbInterface%     = USB_Install, USB\VID_1234&PID_5678&MI_90

Under both

[Google.NTx86]
[Google.NTamd64]

Save and close.

INSTALLING DRIVE:

Find device in Device Manager and Update Driver.

Choose Browse
Let me pick
Have Disk
Browse
select \android-sdks\extras\google\usb_driver\android_winusb.inf
OK
choose Android Composite ADB Inerface
Next
accept unsigned warning if shown. For Windows 8 you may need to enable the installation of unsigned drivers, just Google it.

UPDATE ADB:

Open file \USE_NAME\.android\adb_usb.ini

add to the bottom 0x1234 (this is the VID part with the 0x identifying it as hexadecimal)

Save and close

Restart the ADB by either

Eclipse:

Show the Devices view
Click the facing down triangle in the top right corner of the view
Click reset adb

Command Prompt:

Open command prompt
cd to your \android-sdks\platform-tools\ folder
Run adb kill-server
Run adb start-server

All Done.


Do 4.3 JellyBean apps work on 4.4 KitKat?

There's no gurantee that they'll work, but API compatibility when upgrading is a standing tenet of Android. The odds are very high (above 90%) that they'll work no problem.

In the end, whether they work or not depends on you, as the developer. As an Android developer, you should probably read the documentation released with new API's for the features and methods you use.

One way or another, you may need to upgrade to 4.4 as soon as you can - in order to address potential bugs that may pop up for your users.


Is there any way to shoot a full sphere panorama (horizontal + vertical)?

You can do this with your native camera app. But you have to have JB 4.2 (Not 4.1.x).

Go to the camera. Tap on the camera icon and pick the item that looks like a small globe with a panorama stretched over it. That's the Photo Sphere mode.
Take a picture as usual.
Keep your camera steady.
You should see a message to align your camera with the blue dot. Tilt your camera up, down, left, or right slowly to match the center of the screen with the blue dot for the next area. The picture will snap automatically when you get there.
Keep going for as long as you wish to take as many images as possible and make your complete Photo Sphere.

Note: this may look a little weird if you try to take pictures of people, since they tend to move between shots. Landscapes and interior shots are your best bets.


The Google Search app is able to search the applications on your phone. On 4.1+ this can be done through a Google Now search. On many devices, this is accessible by swiping upwards from the home button in the navigation bar.

When you search for the app on your phone, you can use the bar along the bottom to scroll to "Phone" to search your phone rather than the web.

You can also search "start " so for example if I had an app called (in your case) "Battery", if I typed into the search bar "start battery" it would give me a card showing the app name and icon with a button below saying "Open App"


my mobile data is not working after i reseted my sumsung galaxy note 3

Reset network setting again. Manually enter APN setting. For that
Go to setting / connection  / mobile network / Access point name. Manually enter apn details.
Turn off data saver. Go to setting / connection / data usage / data saver.
Make sure you have good network signal. Other wise reinsert sim.
Update mobile software.
Make sure data roaming is off. setting /connections  mobile network / data roaming.
Temporary remove from network and again reconnect to network.


Your phone has two spaces where it can store apps, the internal memory and the SD card. It seems like the internal memory has filled up completely. To remedy this, go to Settings > Apps and move any apps you can to the SD card/external storage (by clicking an app, then click 'move to external storage' or similar). This will free up space on internal storage for it to download updates etc. whilst keeping the apps on your SD card.

You should do this for all the apps you can, as long as you don't need them to run in the background; for example, you should not do this with apps that provide widgets, or alarm clock apps.

A tip: don't ask questions in all-capitals; it doesn't encourage answers.


Why does scanning for carriers take so long?

Your cellphone searches for a predefined (by the vendor) time (in your case about 1 minute) for available carriers and then displays the result. The delay is there to make sure there are as well the towers available for you to choose from which have a weak signal and loose some packages on the way.

You can not change that behavior in your Galaxy S4 mini.


Is there a way to have my device say the callers name when the call is coming in?

Sanity is another neat app for this.

Alternatively, it is straight forward to configure a Tasker profile to 'say' an alert including the caller's name.


Why can't I change my password in system settings? Nexus 6p Resurrection Remix Pie

Don't worry I factory reset and it started working again!


Theoretically all Android systems can be rooted. Rooting is, basically, introducing an su executable to the system, mostly done under recovery environment. The basic rooting process is simply putting an su under a specific directory, while advanced rooting gives a complex su executable as well as a GUI application for you to manage root permission management, to grant and to revoke. Besides, an engineering build of Android OS has root already enabled (stock su), so there shouldn't be an 'unrootable' Android OS.

Is there any way to share data(not through cloud) between multiple users in lollipop nexus 4 device

I think the first answer (by June Lau) misses the point - the question was about sharing files between different users on the SAME device. I have been using subdirectories that I created within android/obb with success. In my Nexus 7 tablet the exact path is /storage/emulated/0/Android/obb/. The issue is that the media browser does not see files in there, so that one needs to use some file-manager software (search for 'File Manager' in the play store) to get to the file and start its reproduction from there, or for moving the file into the user's file-system.


You might want to take a look at Hacker's Keyboard:

A full 5-row keyboard including arrow and Esc/Ctrl keys, intended for tablets.
Are you missing the key layout you're used to from your computer? This keyboard has separate number keys, punctuation in the usual places, and arrow keys. It is based on the AOSP Gingerbread soft keyboard, so it supports multitouch for the modifier keys.

It supports a bunch of keyboard layouts -- though I'm not sure about the "special characters" being inserted using alt sequences.
If you're mainly interested in being able to insert special characters (and don't care whether they are bound to alt-sequences or selectable by other means), I'd suggest to search the playstore for "charmap". This will yield about 10 results, the topmost of them would match your needs.


New version of handcent  with its group sms plugin does the job perfectly.

Record and play sound from Android to a computer - Jack disconnects periodically / Jack undetected - Depending on Android version

Ok, after many attempts, I have found where the problem lies.
TRRS is respecting a standard of electrical impedance.

This standard isn't respected by sounds cards, impedances were highly different.
I tried to simulate an headset only by using resistors.

This jack is detected as headset on all my devices (Android 4.0.3, Android 9 and Android 10).
I found that the impedances are used here to find the type of headphones (TRRS or TRS), when the type is unknown, each phone acts differently. In old version, the audio port is enabled. In newer version, it's disabled.
Another info : depending of the usb connection of the phone and the sound card, noise could appear in the signal. This noise can be high enough to avoid its use.
To conclude :
In my case, I'm unable to create an electronical component that would take out the signal and send it to a jack. I created a solution that could record the signal from Bluetooth.


How to remove unneeded icons from the menu?

By menu, I'm assuming you are referring to the app drawer. I don't know if the stock Samsung launcher gives you the ability to hide apps, but several 3rd party launchers offer that functionality. Apex and Nova both give you the ability to hide and create custom app groups in the drawer. There are free versions of both in the market with each offering a paid version with expanded functionality.


How can I read my text messages from another device?

Remote Control? Hmmmm.

AIRDROID!

Airdroid is an app that allows relative remote control of a device, remotely.
Install it on the 5x, and make sure you create an account. Y'all be needing it. Also, tap the menu, then settings, and disable the confirmation for lite mode and enable keep-awake*
On the other device, go to and bookmark web.airdroid.com DO NOT LOGIN YET!
Disconnect from WiFi on your 'other' device, and in the 5x too if you want. Then, login on your other device.
If all goes well, it will connect to your phone, no issues! Just tap 'messaging' in the corner, and you are done!

*You may need to enable Developer options (Settings -> about phone tap build number 7 times, then back, then pick the new options) and pick stay awake while charging (tick it!) Also, Airdroid is battery consuming, so keep it on charge!


Wifi connects for sometimes then disconnects and then never connects

I have been testing one of my app on spice stellar phones. The problem seems to be with the phones as the Mac ID keeps changing (yes, that right). It starts with a specific Mac and then suddenly the Mac ID exposed to the network changes and the phone is dropped from the network. If I Forget the wifi connection and reconnect, the same behaviour is observed at random intervals.


I would suggest using Titanium Backup. It has extra features for rooted devices, but normal app and data backups work fine wihtout root.


Might very well be a hardware problem as doing a factory reset also hasn't helped. It's best to get your phone checked by an authorized technician.

Which android devices have optimized encryption hardware?

Fundamentally Android requires the developer to implement encryption directly (ie, there is no OS supplied framework for this).

To the best of my knowledge, there is no current Android hardware with Encryption built into to the hardware.  The new "Black Phone" that Boeing is reportedly making for the US defense industry is likely an exception to this (the phone HW was specifically engineered for security).

Basically iOS is encrypted by default, and Android requires the devloper to implement encryption in their applications.


Wifi connection with username and password

That pop-up page is called captive portal.
You have to sign into it using your given username and password in order to connect to the internet.

In your phone you are not automatically redirected to the captive portal.
You can manually go to captive portal by entering the URL of the portal to the  address bar of your browser.
Find the URL from your friends phone.

Connecting android device with PC using HDMI (video recording)

This is only any use to you if your PC has an HDMI input, which is very unusual. You'll only have such a thing if you deliberately bought video capture hardware and attached it to your PC. If you have such hardware, you should use the video capture software that came with it. Trying to use Camtasia to capture it would be like trying to use Camtasia to capture from a webcam.

In addition, depending on what adaptor you use, your video capture hardware may also need to support MHL (the wire protocol used to send video data over the micro-USB and HDMI connectors). See my answer on How does MHL work? for more details.


The application SayMyName Dessert does this quite well.


Change color scheme on Samsung Galaxy S4 running Lollipop 5.0.1

The Touchwiz Lollipop skin has a limited number of color schemes available to use that can be accessed through Developer Options. I am not entirely sure what the purpose for them really is since they merely drain away colors and mute everything. Anyway, the new way to access Developer Options is to go to the About Device under the More tab in your settings and scroll down to Build Number. Keep tapping Build Number until the Developer Options are turned on (you will see a message below where you are tapping). In the Developer Options now under the More tab, scroll way down to Simulate color space. You'll 4 options including grayscale/monochromatic.

In my opinion, these options suck. I've had my S4 for 2 years. Maybe it's time to pick up a phone from another manufacturer.


Never seen this before!
Anyways here is the steps i would do:

1. If you are sure that the 15.9/16GB is wrong, e.g you know you haven't got that many apps/videos, then proceed to step 3.

2. If you know you have got like more than 50 apps or really many videos, take some time and delete videos/apps (of course images, otger files too) that take much storage.

3. Go to Setting > Device Mainteance and then clean everything you can (optimize the phone)

4. If that doesn't work go to like a phone reparator and check what they can do.


Text messaging Force Close issues after OS upgrade

Try clearing the cache of the Messaging app.

From the home screen:

If that doesn't work, I'd try the following, in this order:

Force Stop
Restart the phone (off then on)
Clear data (will likely lose your SMS messages)


Why is my Android not restoring the app data from its Google Drive backup?

I'm going to post an alternative answer to my own question, in spite of having accepted the previous answer. The reason is that I have since learned, on my personal device, that the Android Backup and Restore doesn't work as well as I expected, so while that wasn't the case in the case above, this might be the case for other people finding this question.

Apparently, if restoring on a different device or even on the same device with a different OS, it won't restore anything but system data. This happened to me when I wiped my Moto X (2nd gen) to install LineageOS on it.

That means that notification settings, WiFi passwords and background images will get saves, while app data (save games, app settings, etc) will not.

I'm not sure if newer versions of Android come with better Backup and Restore functionality, but for now I'm going to be using a specialised backup app (Helium at the moment) to keep my data fairly backed up, and also use that when transferring to a new device.

If anyone has any positive experiences with Android own Backup and Restore actually restoring app data on a new device, please share any details of android versions and device :)

Update on Helium

Here's a few words on my experience with Helium so far.

At first I was a bit disappointed, due to a few limitations of the app. Using the free version you can't setup a scheduled backup, so I had to start it manually every time. This, however, became extremely tedious, as you can't save a "selection" of apps to back up, and so had to scroll through all your apps each time. So I bought the premium version, so I could set up scheduled backup tasks.

But for some time this also didn't work, because the app kept losing "authorisation" or whatever it is, so I had to connect it through USB with USB debugging enabled and running the Helium desktop app every time I wanted to do a backup. And you can't just trigger a backup, only change the scheduled time until "in a minute" and wait...

Then that seemed to stop being a problem, and authorisation isn't lost any longer, even over restarts. But another problem is that the backup can't run if the screen is locked. I'd like to have the backup run automatically in the night, while my phone is charging and on WiFi, but I only wake up to a message about the backup not having been able to run, because of the screen lock. This is easier to fix, by simply tapping the message to run the backup, but means I then have to leave the phone until done.

Over all it works and I'm glad I've got backups (backing up to Google Drive), but it could work a lot better.

I still haven't tried restoring, so there might be a call for another update when I've seen how well that works :-)

Update 2 on Helium

It's started losing the authorisation all the time again, which means that the automatic backups aren't happening, and I have to re-authorise and re-schedule to "now" to trigger them. Would be great to hear from any other Helium users out there, if they have some experiences with this.

Update 3 on Helium

It's not losing authorisation as much, which is probably because my phone isn't restarting as much (I've got a new battery). Also, there have been some updates to Helium, so now you can save selections of apps, which is really handy if you want to update which apps you backup in a recurring backup (almost as handy as if you could edit the recurring backup's settings).

Is it possible to use usb drive/sd card as internal storage?

A feature called Adoptable Storage allows the Android OS to format an external storage media as a permanent internal storage. The data on the adopted SD card is encrypted and it can’t be mounted on another device.

Here are the steps to adopt your SD card:

Put the SD card inside your Android phone and wait for it to get detected.
Now, open Settings.
Scroll down and go to the Storage section.
Tap the name of your SD card.
Tap the three vertical dots on the top right corner of the screen.
Tap Storage Settings.
Choose format as internal option.
On next screen, you have the final chance to decide whether you want to change your mind. Tap Erase & Format if you want to format your SD card as internal storage.
You will be notified if Android finds that your SD card is slow. Tap OK to continue.
You can start the data migration process now or do it a later stage.
Tap Done to finish storage adoption process for your SD card.

Why does Google Wallet depend not only on the Phone but the Carrier as well?

The Google Wallet Privacy Policy specifies that personally identifiable information and transaction data are only shared with the carrier if necessary to allow carrier billing (that is, where purchases made via Google Wallet appear on and are paid through your phone bill).

The relationship between Google and the carriers for this purpose is a purely business one. The only involvement of the carrier in the transaction is (a) if carrier billing is involved, as I said above, or (b) if you use 3G to make a payment over Internet, instead of through NFC. As eldarerathis says, several carriers have payment services that compete with Google Wallet, and Google can't afford to fall out with carriers.

If you're worried about privacy from your cellular operator, please do remember that they have the ability to "customize" your ROM, if you buy your phone through them. Software that monitors your on-device actions and purchases might already be installed on your phone, before you even start using Google Wallet


How to hide updates from market? (Given Titanium backup "detach from market" doesn't work)

Save a copy of the original .apk file and keep it backed up.

A bulletproof way to get cut off from Google Play's update mechanism for that app is to re-sign it with a different key, then reinstall the newly signed apk file. Google Play (maybe) will still offer updates** for that app, but installing them will eventually fail because of the different signature. ApkTool will do it for you:

me@local:/tmp$ java -jar apktool.jar decode --no-src FDroid.apk fdroid/
I: Copying raw classes.dex file...
I: Loading resource table...
I: Loaded.

me@local:/tmp$ diff -rq FDroid.apk FDroid.new.apk
Files FDroid.apk and FDroid.new.apk differ.

ZipSigner2 might also help you do it (just found it on Google Play).


Here's a way to do it using TWRP

Put the superuser.zip file in your tablet and Boot into Download Mode (Hold Vol Down +Power to turn on the Device).
Unzip the TWRP Recovery Image after downloading it below.
Connect your tablet to your PC, unzip and run Odin, click the PDA button and select the TWRP md5 file you just unzipped.
Begin holding the Volume Up button on your Tablet and hit the start button in Odin (this will ensure you reboot into the new recovery)

Once in TWRP if you select the reboot option under advanced you should be prompted to root your device if it's not already rooted. If that doesn't happen for some reason you can use adb to sideload the SuperSU zip I've attached, or put it on an sd card and find the flash zip from sdcard option in TWRP to flash it.

Download files

 Odin307.zip
SuperSU-v1.93.zip
TWRP-2.6.3.0-recovery.tar.zip


How much battery does using live wallpapers drain?

Different wallpapers drain the battery differently. It really depends on how many different factors the wallpaper is paying attention to. Is it just being pretty or is it altering itself based on every movement of your phone?

The best way to find out is to simply test it yourself. Spend one charge of your phone running a live wallpaper. When you get near the end of the battery charge, open up your phone's settings. Go to "About Phone" -> "Battery" -> "Battery Use". This screen will show you all services that have used up more than 2% of your battery's charge.

Your first reaction will probably be that it is taking up a lot when you see "Display" draining the most but that isn't taking into account wallpaper. The live wallpaper, if it has used more than 2% (some don't), will show up as it's own service.

They will pull more than a normal wallpaper (that's a given) but some won't effect it the battery charge nearly as much as say your widgets or the brightness of the display. Turn down the brightness and you could probably offset the difference in battery charge of running a live wallpaper.


Note: answering my own question as nobody knew.

I did a packet capture after selecting Menu -> Accounts & Sync -> Auto-sync (also accessible via the "Power Control" widget). What did I discover?

To my horror (http requests from phone displayed below):

GET /proxy/calendar/feeds/myaccount%40gmail.com HTTP/1.1
Accept-Encoding: gzip
Authorization: GoogleLogin auth=_hidden_
Host: android.clients.google.com

and

Authorization: GoogleLogin auth=_hidden_
GData-Version: 3.0

My contacts and calendar are being transmitted unencrypted! I don't currently synchronize gmail so I couldn't say if that is unencrypted either.

Also the stock market application (which must be a service because I don't have the widget displayed or the application active):

Completely unencrypted request for stock quotes: just think, you could sit in Starbucks in the financial centre of your city and packet-sniff what quotes were important to all the smart phone users around you..

Other items that were not encrypted:

http request to htc.accuweather.com
time request to time-nw.nist.gov:13 (doesn't even use NTP)

About the only data that is encrypted on my phone are the mail accounts I set up with the K-9 application (because all my mail accounts use SSL - and fortunately gmail accounts are, by default, SSL; and yahoo! mail supports imap using SSL too). But it seems none of the auto-sync'd data from the out-of-box phone is encrypted.

This is on a HTC Desire Z with Froyo 2.2 installed. Lesson: do not use phone on open wireless network without VPN encrypted tunnelling!!!

Note, packet capture taken by using tshark on ppp0 interface on virtual node running Debian connected to Android phone via OpenSwan (IPSEC) xl2tpd (L2TP).

My Samsung Galaxy Ace disconnects from Wi-Fi when sleeping even after setting the Wi-Fi sleep policy

I found this somewhere -- and it works for me.

Here is the solution that worked perfectly with me:
the problem lies in the DHCP settings of the ADSL router.

FOLLOW THESE STEPS TO SOLVE THIS PROBLEM.......

Login to your router and go to DHCP settings (for belkin its 192.168.2.1) and find the item called leasing time. The default values of the leasing time is usually Forever -- and there is a bug with Android
All you have to do is to change the value of the Leasing time from forever to any other long value (depends on the routers options). Here I changed the value from forever to 2 weeks -- and since then I didn't have a single WIFI disconnect.


Prefer 5GHz over 2.4Ghz without disabling 2.4Ghz

You can take advantage of  the experimental "prefer 5 GHz" feature from WiFi band – or Smart WiFi Selector, which offers that as well:

WiFi Band / Smart WiFi Selector (source: Google Play; click images for larger variants)

Unfortunately, WiFi Band comes with AdMob and Firebase, thus not fully meeting the requirements.

Disclaimer ahead!

I haven't really tested all these applications, so I'm not sure if they fall into the acceptable criteria (firebase, google dependencies etc) besides my device comes with this feature already:

Acknowledgements: How to change from 5GHZ to 2.5GHZ frequency on Android N

In terms of potential 3rd party apps, the closest I have come across is WIFi 5, which is dated , but offers such functionality. It specifies the signal level to switch to a 5Ghz access point and displays a notification showing the available bands.

WiFi 5 was last update 2012, unlisted from Playstore in 12/2017, and thus is only available via ApkPure currently. Not sure whether to trust that site.

Blue light filter turns on automatically at sunset, but often doesn't turn off at sunrise

It turns out that it seems to be related to the power-saving features on the S7. Apparently at some point, the background process that automatically turns the filter on and off at scheduled times got added to the list of processes to be managed by the power-saving mechanism, after which point, any time my phone was in power-saving mode and had not been used recently, the scheduled toggle of the filter's state would not fire. I'm assuming that was just never the case at sunset, as I'm much more likely to have used my phone recently at sunset than at sunrise.


This question was answered on this website. I will briefly summarize the steps I took to allow my RCA Voyager (RCT6873W42) running Marshmallow 6.0 to sync up with my Windows 7 computer and ADB in Android Studio.
1. Install the Google USB drivers.
2. Find the device ID by navigating in Windows to (Control Panel)>(Device Manager)>(Other Devices)>(Android ADB Interface)>(right-click: Properties)>(tab: Details)>(‘Property’ drop-down: Hardware Ids) which yielded

USB\VID_8087&PID_0928&REV_FFFF&MI_01
USB\VID_8087&PID_0928&MI_01

3. Open up C:\Users\Stewart\AppData\Local\Android\sdk\extras\google\usb_driver\android_winusb.inf in Notepad++ and add the following lines after both [Google.NTx86] and [Google.NTamd64]
;RCA Tablet RCT6873W42
%SingleAdbInterface% = USB_Install, USB\VID_8087&PID_0928&REV_FFFF&MI_01
%SingleAdbInterface% = USB_Install, USB\VID_8087&PID_0928&MI_01
(Notice that you have appended the the device IDs you obtained in step 2 to the direction%SingleAdbInterface%=USB_Install,.)
4. After saving android_winusb.inf, navigate back to device manager, right-click on the unknown device (Android ADB Interface) and choose ‘Update Driver Software…’.
5. Choose Browse my computer for driver software: Locate and install driver software manually. Then choose (Browse), navigating to where the drivers are stored (C:\Users\Stewart\AppData\Local\Android\sdk\extras\google\usb_driver) and clicking (Ok).
6.  Make sure that the ‘Include subfolders’ option is checked and click (Next).
7. If you open up Android Studio with your device connected, it should now show up in the ADB after several seconds.
Note: Some of these details may vary. The location of your SDK will undoubtedly be different. What you write in the .inf file comment is arbitrary. I chose to write ;RCA Tablet RCT6873W42. I assume you have enabled developer options on your device, allowing USB. You should be able to easily follow Google's direction on installing their USB drivers. An additional step was listed on the website (see above) which I did not have to follow.


Phone turned off for empty battery. Now it gives "No command"

I didn't really solve the problem, but I just tried to be sure that the phone was rebooting really from scratch (the purpose of resetting).

I went in recovery mode and I tried choosing "Power off" this time. After that it didn't try to reboot automatically as all the previous times.

I waited a little and then powered it on. Magically it booted correctly and without any issue


Play videos from another android device over wifi

Run an FTP or HTTP server on your Android device which has bigger storage. There are many apps on Play Store which can create a server on Android like FTP Server Ultimate or Servers Ultimate Pro.  Creating a server on them is very easy. You can get an idea from here as well (see #Method 3).

Install a file manager which allows access to remote storage such as ES File Explorer or MiXplorer. Both are very intuitive and can create an FTP server or either access it. (See step 5 here for former's usage.)
It goes without saying that both devices need to be connected under same Wi-Fi or hotspot.

Install a multimedia player such as MX Player to stream videos.

That's it.


Can I hook up an external GPS to Android devices without a built-in GPS?

I believe Bluetooth is the only way to do this.

In order to be able to do this via USB the device would need to support USB-OTG (basically be capable of acting as a USB host); given that you are excluding Bluetooth, I doubt there would be a device with USB-OTG but without Bluetooth. You'd obviously need a GPS capable of sending data over USB, as well.


Samsung Galaxy S GT-I9000 froze during firmware upgrade

I believe the solution is the same as in my answer here: Try different button combinations to get into Download Mode, then try the update.  If the update doesn't work in Download Mode try again from the phone's normal booted-up state.


How can I get a list of all my paid (only) apps in the Play Store?

(1) Check out Legacy Play Store. You can get the list on UNINSTALLED PAID apps. INSTALLED list includes both PAID and UNPAID.

If you decide to install it, you may need to:

use Root Explorer (I had troubles with Astro and File Expert)
copy the apk to /system/app
chmod the apk to 644

NOTE: It works on my Samsung Galaxy S2, running CyanogenMod9.

EDIT: Hmm. Website is currently unavailable. Post a comment if you can't access it. I could probably upload the apk somewhere. [Or you could search for the app elsewhere]

(2) AndroidPolice just featured a GreaseMonkey script that allows you to separate your paid apps in Google Play. You might also want to check it out.


Windows cant see my android phone. SM-J200F

If you want to execute the automatic driver installation, just open the Windows Device Manager, select your phone (if it shows up) and click on 'Update Driver Software'.


Why don't the percentages on the battery chart add up to anywhere near 100%?

Since you have last charged your device, its displaying the ratio [usage time/time since charged] * 100 of that service
It might be that you didnt use any service and the screen was off most of the time
If you use many apps simultaneously (consider using 4 apps at a time) using these all the time till your phone gets discharged will show the time for these apps to be 100% but if you add these %ages for all the apps it will be greater than 100


Can I replace Huawei 40W supercharger with third party charger but still provide supercharging feature?

No
There are three parts to any charging system other than the old 5V,2A charging :

The charging algorithm, which dictates the power to be drawn at various stages of battery charging. It runs on the device incorporated in OS, including low level changes at kernel level. Note that these are proprietary and hence the sales pitch for different OEMs. (See the charging algorithm
(Source
) of an Anker power bank to get a sense of how complex it can be).

The charger which responds to the requests made by the device and varies voltage or current or both as desired by the algorithm.

USB cable that is capable of carrying the power across from charger to the device. This is the easiest to change, if you know the power requirements.

Unless these three are perfectly aligned, you can't get the desired charging performance. That's why OEMs always insist on using their chargers and cables. Without getting into the specifics of the third party charger you are using (non Huawei), it's obvious that it lacks the capability to meet the demands made by the algorithm. Being a 45 W charger, the device does recognize that it is providing high power and hence displays "quick charging" but cannot super charge.you will get the same results even if you try with any non Huawei charger rated say at 80 or 100W.

OEM device-info? I found plenty of confirmation of what I suspected which is a corrupted bootloader. Look at Google issue here, here, and here. OK what you need to do is.

Download a factory OTA for your device.Here is a collection of OTA's but verify md5 to be sure.
Take OTA for the OS you currently have get the upgrade. Based on your other post recovery picture it's KK 4.4.4 KTU84P to LR50
Sideload the next OTA with ADB command.

  adb sideload 0xxxa.signed-nakasi-version-from-version.0xxx9.zip

It should start to load once complete reboot. Don't worry with an official OTA your bootloader needs to be locked.

Repeat OTA sideload but this time from LR50 to LR51.

This should get you back up and running. If somethings off then the OTA should abort. If you need a debugging script refer to first here reference and check with with csm.hrm's example.


That feature does not exist, the only thing I could suggest is to submit a feature request on the Android Issues Tracker.


How to fix "fastboot FAILED (command write failed (Success))" error?

It can be one of the following issues:

1) Your TWRP image is corrupt. Try downloading the image again, or download from another source.

2.) There is an issue with your USB connection. Check your USB ports and the cable, or try another PC.

Also, are you using a Linux distribution? There is a known issue with Fastboot that sometimes causes the error you mentioned in Linux, so try a Windows PC if you can.


After some digging, I found a German site https://durcheinandr.de/technik/smart-standby-welch-eine-option

To save you the hassle of translating, it states that enabling smart standby allows the device to automatically lock and turn the screen off when the phone is placed in your pocket, or on a flat surface.

I barely remember my German. God, that was hard.


Installing android firmware from default recovery mode via sd card

If you can connect it through adb then install modified 3e recovery from this post.

After it you can also install cwm

But if you are unable to connect via adb then download stock signed zip of stock rom and place it in your sd card the try update from sd card.

Edit: you can try placing cwm update.zip in sd card and update from sd card. I know this can look weird but in some old Samsung mobiles I have done it because they did not check signature of zip while flashing.


While doing similar research to upgrade an old HTC Desire I found this article that may help you: Cant add Google account to HTC Desire

It points out that you first need to upgrade Android Market to Google Play.  However in other forums I read that you have to have Android 3+ to do so, though I'm not certain that's true.  But hope that leads you in the right direction.

Also, if you already figured out and answer, please share back, I'd love to know (it may save me time).  Thanks!
