I searched for that one click root tool and found a post in XDA's Amaze 4G forum that has a Mac version.  I would expect it to be the same as for the ZTE Score, you can try it out anyways: http://forum.xda-developers.com/showthread.php?t=1310115


Your contact -Gmail are already saved in GMail isn't it ?

And Photo, playlists are on the SD card, so just keep it / change it / backup it with a card reader

For app settings, some of them are on sd card, and if you use app2sd, all your apps are on the sd card

For your SMS, you can use SMS Backup + to back it up on GMail:

If you have a rooted phone, you can use Titanium Backup ★ root:

Good luck!


Is there a way to remove the Guest account?

Edit: Firstly, please follow the answer here. It offers an easier approach and is tested with Android 7.1.1.

Some users have reported that the following solution didn't work for Android Marshmallow and above. That may be so since I tested this with Android Lollipop and worked well on it.

Yes and No! It depends upon how you want to use this answer.

I still see the guest account icon when I pull down the top bar and click the blue user thing.

You don't need to go that far by completely disabling the guest user to avoid that guest account icon when you pull down the top bar and click your profile image. All you've to do is remove all other users from Settings → Users and change the value of a key.
The key is guest_user_enabled under the table global found at /data/data/com.android.providers.settings/databases/settings.db. This database belongs to Settings Storage app. Its current value would be 1. Change it to 0 using adb with the command:
adb shell settings put global guest_user_enabled 0
Changes should take place immediately, otherwise, simply restart the phone.
Now, whenever you would tap your profile image in the top bar you would see the profile contact (if already created) or a toast saying "The contact doesn't exist". That icon wouldn't show itself as long as you don't create any more users.
Note: As noted above, it is important to remove all other users since the said method wouldn't work as long as any secondary user remains in the system.

The aforesaid technique simply deals with the nuisance that icon is to some users. It doesn't restrict the primary user (owner) to switch or create new user from Settings → Users.
What if I'm happy with having a single user (me) and don't want to see that User in the Settings?
That would require root access. There are devices under the banner Android One which are now running Android Lollipop yet do not have multi-user functionality. It turned out that the [multi-user] feature is disabled (the feature is disabled using framework as noted here) [can be enabled] using few entries in build.prop. Why not use that technique for our advantage?
Hide Users from Settings

Install a file manager with root explorer feature or  a build prop editor app.
The location of build.prop is /system/build.prop. Open the file, go to the end, create a new line and enter fw.show_multiuserui=0.
Reboot the device.

Go to Settings and you would notice that Users entry is missing. As a side-effect, the result in first section i.e. the removal of the guest icon is also covered by this solution.
The good part is that while guest/secondary user is nowhere to be found which you can switch to using GUI, you can still use that multi-user feature. adb shell am switch-user USER_ID can switch the user easily provided that you know the USER_ID of the guest/secondary user which you can obtain from /data/system/users/.
On the other hand, adb shell pm create-user USER_NAME can create a new user too. All good here.

What if I don't feel the need to have my device being used by a secondary user at all? I don't want multi-user functionality in my device?
That can be done. Thanks to Android One technique.
Remove multi-user  feature
We're not removing the feature from the system but simply restricting the system to a single user. As mentioned in the last section, we need to edit build.prop which requires root access.
Add fw.max_users=1 in build.prop and restart the device. This would restrict the system from creating any new user since the maximum user is set to one. It would also hide the entry Users from Settings as well as the guest user icon aka the nuisance.
Note that you can always switch to the guest/secondary accounts using adb shell am switch-user USER_ID even after restricting the maximum users to one since the restriction is set to curb further creation of the users. If you feel the need to remove those users but find it bit problematic that there is no option now to remove them from GUI, then simply do adb shell pm remove-user USER_ID.


What happens if I clear data in my settings

just like phones when you factory reset it, it will go into its original state


Is it possible to replace internal memory of a android phone ?

Yes.

Lots of Taobao (think of it as Chinese eBay?) merchants actually offer services of enlarging RAM and internal storage by replacing the chip, and these are actually quite popular, at least around me. Most are for Apple and Xiaomi phones which are popular and often lacking in storage. For example, they could expand the storage of a Xiaomi MI 5 to 6GB+128GB, a configuration Xiaomi themselves never offered.

Here's a very simple search with the keywords "Xiaomi" + "capacity enlargement" (in Chinese):

The internal storage chip (eMMC/UFS) is not an integral part of the SoC, but on most modern phones, it's packaged together with the SoC, often stacked on top of it, as the picture below demonstrates:

(AP≈SoC)

(Source article - also worth a read)

  Have anybody tried this out ?

There are several factors preventing you from trying it out, however:

The tiny size and mass amount of pins connecting the two together means you need professional devices to de-solder and re-solder them. The merchants above are usually situated in Shenzhen in real life - known for flourishing electronic industry, so they are well-equipped for such, but same can't be said for a random DIYer.
You can't handily buy replacement chips unless you are familiar with the supply chains, and even then you can't make sure what you bought is compatible.
You also need to load the blank chip with basic data (such as partition tables), which usually only professionals have access to.

Even if you are professional enough to overcome all of this, the stability of the modification is questionable - there are numerous examples of unstable re-solder job undermining the connection, causing the phone to fail. Such mods, naturally, are not covered within warranties, and therefore only you get to shoulder the consequences.

TL;DR: YES technically, but NO realistically.

Can I stop system upgrade notices on Nexus 7 5.0.2

If you want to just disable the notification, open the notification drawer, tap and hold the notification so it goes Black with a certain app name and an "i" at the end. Press that "i" and uncheck "Show Notifications" This will result in you not getting any notification from that app.

It's highly recommended that you update, so... to update, you need:

An Unmodified System (You can't have root)
Stock Recovery

I updated my (rooted) Nexus to Android 5 by unrooting via SuperSU, Flashing Stock Recovery, and Updating.
This may or may not work so the best way to update is to take a backup of your data, download the factory image from google and flashing it.

Flashing Stock Recovery

Android is designed to rewrite the recovery partition with stock recovery upon each boot, but installing a Custom Recovery patches the OS so it won't happen. If you deleted your recovery, meaning you no longer have a recovery, stock or otherwise, You might as well flash the update from a stock image. The Android Stock recovery screen is a dead android with an exclamation mark and might mislead you into thinking there's no recovery.

TL;DR: If you want to update, backup your apps and data, download the latest factory image from here and flash it.


Do published Android apps pay for open source libraries they are using?

This would depend on the licence terms of each individual library. For Retrofit for example, I quickly found this: https://github.com/square/retrofit/blob/master/LICENSE.txt which is the Apache licence. It imposes conditions on how you use it, but it doesn't mention that you have to pay the contributors. Other packages may be different - you need to look at each one separately.

Phone switches to watch interface when put against a specific side of my laptop

The tiny watch screen is a feature of LG G2 named QuickWindow when put on a smart cover (a cover that uses magnets to detect if it's closed or opened).

(LG G2 showing tiny watch when put on smart cover)

That indicates there's a magnet field on a particular spot on ASUS Zenbook, and LG G2 reacts to that on a very specific position. (As already confirmed by OP, there's a magnet on the left side of the lid to keep the laptop closed)


Installation aborted when trying to adb sideload to Nexus 7 for upgrading to Lollipop

The factory images provided on that page are not packaged for installation via Android's recovery system. You'll need to use the flashing instructions to install the images using fastboot. If your device's bootloader is not unlocked already, this would require wiping all of your data. If it is unlocked, then you can skip the wipe by flashing just the bootloader upgrade, the the system image, and the boot image:

fastboot flash bootloader
fastboot reboot-bootloader
fastboot flash boot /path/to/boot.img
fastboot flash system /path/to/system.img

The alternative would be to incrementally apply the OTA updates for your device up to the latest version. These are designed to work in recovery mode, but need to be applied in order from earliest to latest since they are patch updates, not full system images. The Nexus 7 Wi-Fi OTA updates can be obtained from Google's servers using the following links:

KOT49H (4.4.2) to KTU84L (4.4.3)
KTU84L to KTU84P (4.4.4)
KTU84P to LRX21P (5.0)
LRX21P to LRX22G (5.0.2)
LRX22G to LMY47D (5.1)

For the GSM-enabled version, you can use these links:

KOT49H to KTU84L
KTU84L to KTU84P
KTU84P to LRX22G
The 2012 Nexus 7 GSM has not received a 5.1 OTA yet. You must currently use the factory images if you want to update to 5.1.

Additional OTA links can be found in this XDA thread, if needed.


A good resource on questions like this is the Tasker UserGuide (link goes to the "actions" page here). Quoting:

  Menu
  Show a selection dialog and perform a different action depending on which item the user selects.

Sounds like exactly matching your purpose, though I haven't tried it. You can even specify a default action, which then would be executed on timeout as well (i.e. when you didn't notice the menu "in time").

The Menu Element belongs to Tasker Scenes. Please refer to the UserGuide Index and check the "Scene" section for closer information, if needed.

You should be able to combine (or wrap) this with an IF statement in case you only want to be asked on a given condition like "Display On".


Summing up from my comments above:
How do signal boosters work?
They work by forcing the device to do a re-connect. Though the device is permanently watching its neighborhood (for the case the signal gets too weak), it does not switch for just a trifle. Instead, it tries to weight the benefits against the costs: switching to a different cell has some signalling overhead to be considered. So if it's just for a trifle, it wouldn't switch. But if the other signal source is twice as strong, for example, it would. And it certainly does switch once you lose signal, even if there's just a weak signal available to switch to.
If it switches, it always choses the best and strongest signal available. And as I said, when you lose your signal it does switch: that's exactly the concept of the booster. By going to airplane mode, it makes you lose the signal, so switching on the radios makes the device connecting to the strongest signal. If your lucky, you see one more bar. If there was just one cell available, you just wasted juice.
IMHO it's not really worth it, but everybody needs to decide that himself/herself. Improvements are rather marginal/cosmetical in most cases, if at all.
Ways to boost without a booster
Well, if you followed my above writing, you might already have guessed it: Long-press your power button, and select "airplane", then do it again. Or, open your notification bar and tap the plane icon, and repeat it. Done. The difference is you need to do it manually – while the app at least partially automates it (maximum one tap with the app, while 4 manually).
Further hints
There are apps available which track cell signals. Some do even track the neighboring cells (most of them only work with selected devices). If you find one that does work with neigboring cells and your device, you should be able to tell the real numbers – and see if it would be worth to "boost", or if it rather would be to "boast" :).


Force the reset and Grab to happen again... After it has grabbed the storage, use this command in Terminal emulator to find what has been added recently... go through them 1 by 1 ...

Also you can use Sort to Sort By Size, and locate the larger files on your Internal Storage...

find /storage/sdcard0/ -mmin -1 (mins)
find /storage/sdcard0/ -mtime -1 (days)


Rooting and updating to Official Updates

I recommend using OTA RootKeeper. From the app description:

  This application makes a backup or a protected backup of your device's root.
  This device must already be rooted: OTA RootKeeper doesn't have the ability to root devices.

It allows you to temporary un-root your phone for OTA updates and then restore back root.

Before installing please check this XDA thread.


Why does my Android device slow down after successive ROM updates without wiping?

I've come up with one potential answer myself: TRIM

Solid state disks (SSDs) and some flash memory require the operating system to perform a kind of housekeeping task to maintain the efficiency of the device.

The operating system command TRIM is explained in this AnandTech article:

http://www.anandtech.com/show/2738/10

Its applicability to certain Android devices, including my Samsung Galaxy Nexus and ASUS Nexus 7 is explained in these XDA Developers threads:

http://forum.xda-developers.com/showthread.php?t=2104326
http://forum.xda-developers.com/showthread.php?t=1971852

An XDA member wrote an app called LagFix which purports to exercise the TRIM maintenance function, thus restoring write performance for the device.

Since I recently performed a complete factory reset, I'm no longer having performance problems and thus I can't directly corroborate the purported benefits of LagFix. If I'm in a position where performance is suffering, I may do some benchmarking and see if LagFix improves the situation.

Please be aware if you plan to try LagFix that there are some devices that have chips that do NOT play nice with this utility. These chips have what's come to be called a BrickBug, and if you run LagFix on one of these devices, you will irrevocably brick your device.

I highly recommend you follow the advice and read the LagFix FAQ. It points to a utility which can tell you if your device contains a chip that may suffer from the BrickBug.

VPN doesn't work on HTC Desire over WiFi

A complete article on VPN on HTC Desire is present on the HTC Europe portal. Hope this will help you out.

  Connecting to a virtual private network (VPN) From your phone, you can add, set up, and manage virtual private networks (VPNs) that allow you to connect and access resources inside a secured local network, such as your corporate network.

  Depending on the type of VPN you are using at work, you may be required to enter your login credentials and/or install security certificates before you can connect to your company’s local network. You can get this information from your network administrator.

  Also, your phone must first establish a Wi-Fi or data connection before you can initiate a VPN connection. For information about setting up and using these connections on your phone, see Data connection and Wi-Fi.

  Setting up secure credential storage

  If your network administrator instructs you to download and install security certificates, you must first set up the phone’s secure credential storage.

  From the Home screen, press MENU, tap Settings > Security, and then tap Set password.
  Enter a new password for the credential storage (at least 8 characters without any spaces).
  Scroll down and confirm the password, and then tap OK.
  Select the Use secure credentials check box.

  You can then download and install the certificates needed to access your local network Your network administrator can tell you how to do this.

  Adding a VPN connection

  From the Home screen, press MENU, tap Settings > Wireless & networks > VPN settings.
  Tap Add VPN, and then tap the type of VPN you want to add.
  Tap the VPN settings and set them up according to the security details you obtained from your network administrator.
  Press MENU, and then tap Save.

  The VPN is then added to the VPNs section of the VPN settings screen.

  Connecting to a VPN

  From the Home screen, press MENU, tap Settings > Wireless & networks > VPN settings.
  In the VPNs section, tap the VPN that you want to connect to.
  When prompted, enter your log in credentials, and then tap Connect.

  When you are connected, the VPN connected icon  appears in the notification area of the title bar.

  You can then open the web browser to access resources such as intranet sites on your corporate network.

  Disconnecting from a VPN

  Press and hold the title bar, and then slide down your finger to open the Notifications panel.
  Tap the VPN connection to return to the VPN settings screen, and then tap the VPN connection to disconnect from it.
  When your phone has disconnected from the VPN, the VPN disconnected icon  is displayed in the notification area of the title bar.


What will happen when I remove my Google account from an Android tablet?

1)  Correct.  You are simply removing your Google account from the tablet, not completely deleting your Google account permanently.

2)  Yes and no.  Yes in the fact you will not be able to access information via apps like Google Drive or Gmail any longer, but if you downloaded any files from them for viewing offline (music, photos, documents, etc), those will still remain on the tablet.  You would either have to delete these items individually, or performing a factory reset of the device (which will remove everything), taking it to the state of where it was brand new out-of-the-box.


Why can't I link contacts? (Moto G Stylus)

In the meantime, I have found out that the dialer of this phone really can't link contacts. What a bummer... I thought this was a basic functionality of all but the most basic phones. (Well, maybe it is, and this phone is just one of the most basic ones.)
In any case, be prepared to add a 3rd party dialer to the bill if you're thinking of buying this phone from anywhere but Verizon.
From Motorola:

The :Link" feature that you've mentioned is only available for Verizon specific phones, so a Moto G Stylus that is purchased from Verizon would work with that feature.


Configure power control in notification pane

Not by default. Certain ROMs like CyanogenMod do allow you to customise the toggles and the order in which they're displayed.

A possible workaround could be this app - Notification Toggle


Which VCF field do I use to specify a group in Android? And how do I get the picture via URL?

Here's a list of valid VCard fields separated into supported/unsupported by Android's vcard importer:

VCardConstants.java

It currently (4.3) says, ORG is supported while CATEGORIES is not. Check it yourself for more clarification.
You may also want to compare what has changed in 4.0/4.1/4.2/4.3 here.


As it turned out: with adb.exe not being in the %PATH% (or $PATH for Linux/Mac users), the batch file was not able to find it. So there are 3 solutions to it:

fixing the batch file to look in the very same directory
fixing the %PATH%/$PATH to include the directory
changing into the directory the batch (and ADB) files are located in, and running it from there

For a one-time run, #3 is the easiest approach:

open a command shell (on Windows via the start menu, open a cmd – on Linux via ALT+F2 and entering e.g. xterm)
change to the directory (using the cd command with the directory as argument; on Windows, you might need to switch to the correct drive letter before)
run the batch/shell script from there

If you need that script more often, it might be worth trying one of the other two approaches. Not being a Windows user, I don't know where exactly to add the PATH information there (AFAIR it was in "Environment variables" somewhere in the settings of the control center); on Linux you can just do so in your $HOME/.profile or $HOME/.bashrc, adding a line like

export PATH=$PATH:/where/is/adb

(of course using the correct path instead of /where/is/adb).

Fixing the script/batch is a little beyond the scope of our site :)


How did my device know where I am located even though my GPS was turned off?

either through trianglation or through Wifi if you where connected

trianglation - sends ping requests to Access Points

Wifi - In window 8 it can give a location based on surrounding Wifi network althought I am not awear of android using this


Installed Gapps, but Google Play services is not there

Open the Play Store and Google Play Services will download automatically.


Since Lollipop, 3rd-party apps can no longer toggle mobile data without root. However, there's a handy new data toggle in the stock quick settings; tap the signal icon, then tap the toggle in the top-right.


Practically, there is no way you can install Android on it. As the device has a software (from my knowledge of China-copy phones) which is just a copy of Android's UI. Also, the hardware is nowhere near the original device (Note II in this case).

Theoretically, Android can be installed on most phone's hardware. There are mods available for iPhone as well! However, there are no mods available (AFAIK) for China duplicates. And like I already mentioned, the hardware of such devices also not capable of running "real" Android OS.

So unfortunately, I don't see a way for you to install Android on this device.

See this question for further information.


Tablet doesn't respond to touch neither when mouse is plugged in, at all

NOTE: THIS WILL FACTORY RESET YOUR DEVICE!
To fix this problem, first shut down your tablet. Boot into the bootloader by booting up regularly, but holding down your power and volume up buttons when you see the logo.
If you haven't installed fastboot, do that first.Then, go to the command line and type in

fastboot oem unlock

Then, find and download a factory image, then run

fastboot flash /path/to/factory/image.zip
fastboot oem lock
fastboot reboot

Hope this helps!


Cat B15Q pairs with Toyota, but connection unusable

Last week, I had to turn in my (company car) Toyota and I got a Peugeot 2008 in return. Of course I tried to connect the Cat to the car. Pairing was no problem. Making a phone call, however, was not possible. But receiving a phone call was possible! This got me thinking. The Cat is dual SIM and in fact I have two SIM cards. In the settings you can choose which SIM card to use as default for outgoing calls, or whether to postpone that decision when actually making a phone call. I had chosen for the latter option, but after I changed it so that outgoing calls always use one specific SIM card, I could make calls with the car's phone buttons!

Maybe the connection with the Toyota had been successful after all, it just got stuck because I hadn't opted for the default SIM card option.


There's a couple of ways to do this:

cat /proc/last_kmsg > /sdcard/last_kernel_message_log.txt
dmesg > /sdcard/kernel_boot_log.txt
plug in the usb cable with the smart-phone switched off. Then issue the command adb logcat from your Windows cmd or Linux terminal, it will hang waiting for the device to come on-line, now power up the smart-phone. The logcat should start scrolling off then.

Since you expressed interest in figuring out how far one's phone gets in the boot stages before it crashes, those methods should help. The thing is you need to be pretty quick to grab the kernel's log (the first two methods shown above).

What I would do is this, on my Arch Linux box, two terminal windows, one for the adb logcat, the other, to grab the log the minute logcat starts scrolling off!

Edit:

BE aware, there are differences with using adb and fastboot!

fastboot works differently, it is only used for flashing images into specified partitions, and is more tied in with the boot-loader process, i.e, it can understand the boot-loader mechanism. It also requires that:

under Windows, 'Administrator' privilege to execute it
under Linux, 'root' privilege

The reason it requires it is because it bypasses certain input/output of the hardware, and thus, does not "talk" in adb protocol, rather, it is to "talk" directly to the boot-loader. Something that cannot be done as a normal user. Here is the help for the usage of fastboot.

$ sudo fastboot
usage: fastboot [ <option> ] <command>

commands:
  update <filename>                        reflash device from update.zip
  flashall                                 flash boot + recovery + system
  flash <partition> [ <filename> ]         write a file to a flash partition
  erase <partition>                        erase a flash partition
  getvar <variable>                        display a bootloader variable

  flash:raw boot <kernel> [ <ramdisk> ]    create bootimage and flash it

A well known-usage of fastboot is for flashing for example, to flash a recovery image: sudo fastboot flash recovery recovery.img, another is to directly flash a raw image, sudo fastboot flash system system.img. For more of for the case of kernel development, using this fastboot boot new_kernel, this temporarily downloads a new kernel and boot using that without touching the boot-loader's own boot.

There is also a limitation on the size of a raw image that requires to be flashed, when I say raw image, I am referring to a file that has a .img extension, the image must not exceed 128Mb. (I found out this when developing ics4blade, after the build completed, the system.img was 162Mb, and I tried to flash it but fastboot refused! To circumvent the limitation, had to create a CWM flashable zip file to do that and get around it!)

Practice caution and ensure the partition is correct and double-check and double-check again, if necessary, walk away from the computer, take a break, come back again, and double-check again, this is where it can go horribly wrong, flash the wrong file into the wrong partition... well shrugs

How can I sign out from gmail in my Android?

Menu button --> Settings --> Accounts and sync--> find your google account there (enter inside)--> remove account...

You cannot remove the account if it is the last google account on your phone, you will have to add a different account before you remove it.


su (short for Switch User) is a binary executable. It's used by Android and other *nix based systems to allow a process to change the user account it is associated with. The reason it's important from a rooting standpoint is that su without any other parameters will switch to the root user, meaning that processes that require root permission for their functionality need to invoke su (since by default they are not being run by root).

Superuser is an Android application (.apk is an Android application package). It works as a sort of "gatekeeper" to the su binary. Applications which attempt to invoke su will be forced to route through Superuser, which will then prompt the user if it is an unknown or new application. The user then has the option of approving or denying the access to su and optionally having Superuser remember their decision so it can automatically apply it for subsequent calls by that app. By doing this, the only apps which are granted root permissions are ones that the user chooses.

The source of both applications is available on Github, and can be examined/audited by anyone who wishes to look at it (Superuser here, su here).

You can find further details - as well as changelogs - on Superuser's website.

Trying to install cyanogenmod on nexus 7 but can't get into Team Win Recovery Project

You can try to do it through command line from your PC.

Install adb drivers in PC 15 seconds ADB installer

Download the TWRP img file for Nexus 7 from twrp website TWRP for Nexus 7

Rename the downloaded img file to "recovery.img" and move this to the ADB folder that was downloaded earlier. Make sure you have ADB.exe, fastboot.exe and the recovery.img in the same directory

Enable developer options and USB Debugging in your device

Connect the device to PC. Make sure device is detected if not download the USB drivers.

Once devices is detected, open a command prompt and change location to the ADB directory. Issue the command "adb devices". This should give your device ID as the output.

Executive the following commands carefully:

"adb reboot bootloader" - the device will reboot in fastboot mode
Once device shows up fast boot screen, type " fastboot devices " and make sure device ID is listed
Type "fastboot flash recovery recovery.img" . this installs the TWRP image into the device. If successful you will see an Okay message in command prompt.
Issue command "fastboot reboot" and wait for device to reboot normally. Once this is done you can try the key combination to boot into recovery.  If everything went well you should be greeted with the TWRP recovery instead of the stock Android recovery.

Hope this helps.


How to update Galaxy S4 GT-I9505 from Lollipop to Nougat Android 7.0 version?

It's simply not available, and likely will not be due to S4's age (3+ years - most manufacturers won't support beyond 2). See how it doesn't even get Marshmallow yet?

There is much 3rd-party development for the device, however, and an AOSP-based Nougat ROM is available. You do need to dive into the world of flashing custom ROMs (*) which could take some time, there will be bugs in the beginning, and you will lose many Samsung-specific features should you decide to do the switch, but it's the only way out if you want to stay on the cutting edge.

*: On Samsung devices, flashing a custom ROM usually doesn't require root, but custom ROMs often come with root.

Would Cyanogenmod be faster than stock Android?

Actually, rom experience varies device by device (even for same models, it is possible that you may have more/less stable feeling for rom than others).

  so would a CM ROM fix stuff like this?

Yeah there is no memory leak in CM 12.1 right now, that I can assure you.
Stable builds will take a while. Nightly arent bad, I use them too. It really does have a great performance. Never froze in my case, customization is awesome as well.

Now I cannot (and no one can) guarantee same experience for you. I can only give you an idea of what CM 12.1 is now. So->

Its quite very stable. I cant even remember last time I faced an issue on it. Although RAM is not something I bother about, but CM actually leaves my phone with far better free ram than stock.
I Dont have HTC ONE M8 so I dont know how the stock rom was. But on my phone, CM is far better than stock.
I do face some lags. The frequency is somewhere around just 2-5 per day (not more than that definitely, infact I barely notice this).
You can actually push the performance further. Install a custom kernel, get a better governor (my personal fav is interactive v2). Probably overclock it a little (not needed really, but in case you feel like...). There are a lot of tweaks a kernel can do alone.

  So bottom line, should I flash the nightly Cyanogenmod ROM, if I'm
  looking for stability, speed, and maybe a bit more customization?

Yes. I cannot say for definite that your experience will be mind blowing and stuff. But CM is one rom you must never judge before you actually try. As I said, even its nightlies are very stable given the amount of time they had to correct bugs. As for customization, it has a great theme manager that allows you to control a lot of aspects separately (different theme for notification panel and statusbar, fonts, bootanimations, icons etc etc), so the customization capabilities are ofcourse far better than stock.

In fact, a lot of roms are ported keeping CM as base. CM is known for its stability and speed (and probably minimalism too if you uninstall those pre-installed bloatware apps. The optimized drivers are another great thing), hence it makes porting roms easier. Definitely worth a try.


Yes, it works. You just need root to do this:

$ tsu -a
# cmd package compile -m everything -f

Or:

$ tsu -c '/system/bin/cmd package compile -m everything -f'


My sense home screen has stopped auto rotating, how do I fix it?

From everything I've read, it appears that the Desire Z version of Sense only rotates the homescreen when the keyboard is out.

You could try installing a custom ROM like this one at XDA that supports rotation.


Accidentally tried to flash rom after doing saferoot (not possible)

Can you enter into recovery of download mode?

As your phone is booting up, (right after the phone vibrates), press and hold on Volume Up and Home to enter recovery. Volume Down and Home to enter Download.

If you can enter either of these, there may still be some hope by flashing back your stock Verizon rom through Odin.

Otherwise, you will need to send it in for servicing.


My apps can't save my input or choice in android 6.0.1, how to fix it?

It's not the answer you were looking for but what I would do if I were in your shoes would be to install the latest TWRP (assuming you rooted) and download the latest "hammerhead" for Nexus 5 (GSM/LTE) 6.0.1 (M4B30X, Oct 2016).

After you get the .zip, unpack it to a folder. You'll see

bootloader-hammerhead-hhz20h.img
radio-hammerhead-m8974a-2.0.50.2.30.img
image-hammerhead-m4b30x.zip
flast-all.bat

Unpack that enclosed zip as well to get:

boot.img
cache.img
system.img
userdata.img
recovery.img

Edit flash-all.bat to something like this:

@ECHO OFF

::PATH=%PATH%;"%SYSTEMROOT%\System32"
fastboot flash bootloader bootloader-hammerhead-hhz20h.img
fastboot reboot-bootloader
ping -n 5 127.0.0.1 >nul
fastboot flash radio radio-hammerhead-m8974a-2.0.50.2.30.img
fastboot reboot-bootloader
ping -n 5 127.0.0.1 >nul

fastboot erase boot
fastboot flash boot boot.img

fastboot erase cache
fastboot flash cache cache.img

fastboot erase system
fastboot flash system system.img

fastboot erase userdata
fastboot flash userdata userdata.img

::fastboot flash recovery twrp.img     // this one if rooted
::fastboot flash recovery recovery.img // this one if not rooted

echo Press any key to exit...

You mentioned you flashed a factory image before so I ommited the information about how to set up and use fastboot.exe but the details can be found here: https://developers.google.com/android/images

I don't know that this will fix your cache issue but it is a more complete flash method than running the stock flash-all.bat.


There is a bug report that has been filed to AOSP about this with a FutureRelease status (a bug fix will be coming soon). Read it here.

  It seems that a reboot provides a temporary fix for the problem.
  A factory reset fixed the issue permanently for most users.

Fast Charging by Qualcomm 3.0- impact on battery?

Short Answer

From battery health point of view, Qualcomm Quick Charge 3.0 is comparatively better than Qualcomm  Quick Charge 2.0, since power used for charging is better controlled, resulting in lesser heat

Quick review of concepts (optional read)

Essential concepts  are summarised here in bullet form. Some of these have been elaborated in  How does Fast Charge work?

Charging Efficiency:  Conventional (not fast) charging efficiency is close to 100%

  Charge efficiency is about 99 percent and the cell remains cool during charge.

Heating of Battery while Charging:  is inevitable, given the space (lack of) for heat dissipation but needs to be in limits - All about Battery Chargers says

  Li-ion should not rise more than 10ºC (18ºF) above ambient when reaching full charge.

Battery charging stages each requiring different Power (= Voltage multiplied by Current) as depicted in Fig 1. As an example, as battery charges up, it slowly draws less and less current, which is partly why it takes longer to charge the last 20 percent than the first.
Adverse effects of quick charging: Quick charging, turbo charging, adaptive fast charging, rapid charging are different names meaning the same- fast charging. OEMs have  implemented it under various trade names ) speeds up charging process by increasing power. This has adverse effects on health of battery

a)  Battery is not fully charged, since it does not spend adequate time in all the stages of charging (which happens during conventional charging)

b)  Heating up of battery. Power which cannot be absorbed by the battery (for charging) is dissipated as Heat, which is the biggest enemy of battery.  Ideally,   Fast charging of most batteries should be

  limited to a temperature of 5 to 45°C (41 to 113°F); for best results consider narrowing the temperature bandwidth to between 10°C and 30°C (50°F and 86°F)

c)   As a combined effect of a) and b) above, battery life is adversely affected both in short and long term (incomplete charge and reduced life cycles )

Long Answer

Qualcomm Quick Charge 2.0 supported four modes at varying power levels, 5 volts/2amps, 9V/2A, 12V/1.67A, and a 20 volt option
Qualcomm Quick Charge 3.0  has major new feature  INOV (Intelligent Negotiation for Optimum Voltage), which allows for

  A fine tuned power output and a more optimized charging cycle. Quick Charge 3.0’s INOV communicates with the device to request any voltage between 3.2V and 20V at 200mV increments, allowing for a wider selection of voltages
  INOV has the added benefit of being able to dynamically adjust the charging voltage over the battery charging cycle

( Linked source has a video explaining this and graphical comparison is pasted in the  section at end of answer )

This granular variation of voltage to control power , results in

  27% faster charging than Quick Charge 2.0 (2x faster than the original Quick Charge 1.0) while
  Reducing power dissipation by 45%
  Increasing power efficiency by 38%, and being friendlier to the battery life cycle.
  You're looking at 4 times faster charging compared to regular charging, and devices capable of jumping from 0% to 80% in about 35 minutes.

To summarise, granular fine control on voltage and in turn on power supplied for charging is the key innovation  that results in these improved figures.  Qualcomm Quick Charge 2.0 had only one  voltage level relevant to mobile devices- 5V, whereas Qualcomm Quick Charge 3.0 has  9 variations possible from 3.2V to 5V in steps of 200 mV. This granularity offers tight control on power delivered for charging in a dynamic manner as required

Point to note, is that controlled power supply for charging means less power wasted, therefore less heat and better for battery

To good to be true? This technology looks impressive but there is a major caveat

All comparisons are with reference to Quick Charge 2.0 and comparative figures for version 2.0 over Quick Chargeversion 1.0 or with conventional charging are not available in public domain ( for obvious reasons, for that matter, similar figures for Qualcomm Quick Charge 2.0 over 1.0 are also not available)
These figures reflect the capability of Qualcomm Quick Charge  technology. Realization in device depends on hardware and OS implementation

Compatability with old chargers: Quick Charge 3.0 will be backward compatible with the technology's previous iterations (so your old chargers and cables should still work), and can be implemented with USB Type-C, USB Type-A, MicroUSB, and proprietary connectors.

Conclusion

Qualcomm Quick Charge 3.0 is safer than Quick Charge 2.0 as far as battery health is concerned as indicated by figures shared
Whether you get the claimed performance is yet to be seen. HTC A one 9 appears to be the first device to hit the market with this technology and we should get better feedback as more devices enter with this technology
Charging by power pack/ power bank (to avoid being in a battery drained situation and when you don't have access to mains) is a better option over fast charging
Regular charging using a standard 5V 2A ( conventional charger ) should be preferred mode with fast charging resorted to when actually needed
Most of the battery apps on Play Store measure the battery temperature also. You could measure the temperature after charging and compare with guidelines mentioned at 2, 5 of "Quick Review of Concepts" to get an idea of how it affects your device

Why is Install button still greyed out in absence of screen filter apps?

It means Your Device Doesn't Support the app


Click on settings > backup and reset > factory reset then say yes to clean your phone.

If you try to factory reset your phone, this will do your phone automatically update your phone with initial version of your applications.

Then try to update your respective built-in application from play store, it will solve your solution.


Can I schedule my Android phone to mute notifications of a specific app at specific times?

No, the only way is to enable "Don't Disturb" mode and adjust priorities so you can just receive notifications for the selected priority type on weekends for example


If your volume down button isn't broken, may be the "fast boot" feature is activated in the settings (not to be confused with fastboot) that can prevent the phone from booting in the HBoot.
Try this:

From the lock screen, press the power button
Then select reboot or restart. The phone will reboot
Hold volume down button before the phone power itself on.
You should be in the HBoot Menu (3 android guys)
From the just select Clear data

Hope this helps you.


That doesn't exist on your device.  It doesn't on my Vibrant either, though I can get somewhat similar info via cat /proc/partitions.


Not stock, you would have to install a custom ROM that is specifically designed for your device, they are not generic... Check XDA here: https://forum.xda-developers.com/redmi-pro in the Xiaomi Redmi Pro ROMs, Kernels, Recoveries, & Other Development section. Make sure to do your research and understand the implications and process of installing a custom ROM before starting. Reading in the various XDA forums under your device is a good place to start.

In looking in the development area for your device, it seems the only Nougat ROM in active development is LineageOS 14.1, which is still in alpha stages since some things are not working, major things like calls, camera, mobile data, and more, some major hurdles to overcome yet.

So to answer your question regarding your device, yes, you can but you will not have a fully functional device at this time. I would monitor those areas and see if development continues otherwise it appears you are stuck on Marshmallow.

To answer your generic question, "Can I Install Stock Android 7 N On Any Device?", no you cannot... Android ROM's must be built specifically for each device, they are not generic and not even the same for very closely related devices in almost every case. Some devices have Nougat support from their manufacturer, some have it from third party ROMs, and many do not and will never have it.


So you are asking about a native Android X server? That's the only article on a native X11 I found so far. All others seem to work with VNC somehow.

Not sure how the current state of the linked project is, as I could find no additional information (yet).


As long as you reflash both the boot partition and the system partition it will take you back to a stock version of Android. The kernel is packed in the boot image, so that will overwrite a custom one, but a system image alone will not.

You could also choose to flash back to a stock recovery, but that has no real bearing on the Android system itself and custom recoveries are much more robust, so I would personally not recommend reflashing recovery.


Why do I see adverts after closing WhatsApp?

Like KeshavaGN, I suspect a 3rd party app behind this. But neither your Nova Launcher, nor WhatsApp itself. To isolate the culprit, I suggest the following steps:

Check with e.g. Appbrain Ad Detector (or TrustGO, which you chose) for apps carrying ad modules. These might include your culprit – but on a second look, that's not a typical "ad network message". Anyhow, note them down.
See my answer here for how to check for apps having certain permissions. As described there, it's a "full-screen ad" here as well, so the SYSTEM_ALERT_WINDOW permission might be involved. As it happens always on closing WhatsApp, also check for GET_TASKS (allows an app to check which apps are running) and GET_TOP_ACTIVITY_INFO (details on the app running in foreground). Again, make a note on matches.
Keep an eye on what apps are advertized. Try finding them at Play (better not by clicking on the ad, but separately – though the URL behind the ad might reveal more). If it's always the same dev behind it, check whether you have an app from him running on your device. If that's already on one of your lists from above, you most likely have found your culprit.
Hard to realize, but possible while on some WiFi you control the router as well: If that popup is open, cut the Internet connection behind your router (i.e. your device is still using WiFi, but cannot reach the "open Internet"). Now it shouldn't be too risky tapping the ad (hopefully). I'd expect it opening your browser, which now cannot resolve the page – but you should see the URL in the browser's address bar. This might help to further narrow down suspects, if it is related to any of the apps you're using.

Finally, check your lists created during these four steps, and watch out for matches. If there's an app on list 2+3 (and optionally more), that's a pretty certain candidate. It gets even more likely if it's also on at least one of the other lists. Continue as described in the answer I've linked with item #2.

If you found out the responsible app, additionally to the steps described in the other answer, it would be a good idea to report your finding here as well ;)

Cannot skip WiFi in Google Setup Wizard after Factory Reset

I was stuck with the same device for 1 month.
I finally got rid of this by DNS cheating.

Setup your own DNS server
Add a primary zone named status.eqoe.cn
Add a ressource record A type on the zone with target 216.58.204.110 (IP found resolving clients1.google.com, setup android site)
Declare your own server as DNS in your wifi setup
Now setup your device and don’t forget to forget your wifi settings (in order to flush dns cache)

You will access standard google android setup, instead of unresponsive eqoe.cn one.

When your device is ready to work you can discard DNS setting on wifi setup


Sync to my own server for contacts, sms and notes?

The most complete solution for private contacts and calendar sync seems to be installing the CalDAV-Sync and CardDAV-Sync apps on your phone and setting up a CalDAV / CardDAV server.

TWRP 3.3.0 cannot decrypt data partition (of Android 9)

Well, sorry for bothering. The solution was simple: Don't use the wipe function of TWRP but the Format Data button in the wipe menu.

I was able to factory reset and install a different custom rom.

BTW: Don't use TWRP for Android >= 9 (Pie). As of Version 3.3.0 TWRP lacks the vendor partition feature. Pitchblack seems to be the standard now.

Edit: I think the problem is: Android 9 introduced the quota feature of the ext4 filesystem. TWRP doesn't know about it yet.

Now contacts moved to Archive label will not be shown in list.


Documentation for adb shell getevent / sendevent

There is some documentation on the AOSP site:

getevent

Plus several Howtos like e.g.

Android, writing events low level touch screen automated shell
Turning the output from getevent into something something that can be used
How to emulate key presses
adb shell sendevent, sending touch like events
Android, low level shell click on screen

However, the answer to your question on Google Groups states:

  No, this is fairly device-dependent.  getevent prints a summary of all the devices so you know what those are.  The data generated for a device are generally the Linux kernel's event protocol, so you can look there for further help, but there is no guarantee that a particular device will be following those conventions.


How can I hide an application from the app drawer?

You can use a different launcher, like ADW launcher. Free, and has that function.
On the downside, it consumes a bit more of RAM.


Your best source probably is Nexus S: All Things Root Guide -- which is a compilation/collection of several guides. Here you can probably pick your minimalist solution as well as go for the "big thing". In case you need some addional sources (easily to find with a simple Google search, by the way, as that is what I just did):

Root and Recovery for the Nexus S: Quite decent, looks really easy: Only a few steps involved.
Guide to Root Nexus S: a detailed guide
Nexus S: Full Update Guide: Full guide from root up to CyanogenMod CustomROM
"nexus s" rooting guide: Google Search which turned all the above up on its first result page ;) And probably has many more on the following pages...

Don't get me wrong: I'm not saying you didn't search (your question clearly indicates you did). I put this just for reference by other interested readers here, who might need more details.


Remove 'Driving mode' from status bar dropdown?

Go to the phone Settings. Click Display from the Device group, then on the next screen click Notification panel. You can add and remove notification bar items from there.

Not all Samsung ROMs have this option: in particular, I don't think the Galaxy S III had it until 4.1.2.


google search android app cannot find installed apps

this is just google wanting you to use the search box to generate paid clicks for them. it doesn't make them any money to help you find apps on your device, the search box is there for a reason - to send you to the web and click on ads.


How to automatically switch between apps and/or websites on Android?

Clearly a job for Tasker (see also: tasker, automation). You could create a profile being active permanently, and assign it a task running in a loop. An example could look like:

  Condition: WiFi connected (your WiFi SSID) have it running all the time while connected to your WiFi
  Task:
FOREACH %item 0:3
  LAUNCH APP (Google Calendar) IF %item = 0
  LAUNCH APP (Clock) IF %item = 1
  LAUNCH APP (Weather) IF %item = 2
  WAIT 5 min

The "LAUNCH APP" action lets you select the app to launch. So the loop would count from 0 to 3, launch the corresponding app, then wait 5 minutes (i.e. the app stays in foreground for those 5 minutes). Once #3 has been processed, the task would quit – but should immediately be re-launched, as the condition is still met.

I've not tested this specific configuration, so above is "plain theory" – but should get you started. You can consult the Tasker User Guide for available commands etc, but Tasker also offers a context-sensitive built-in help. Get yourself a 7-day Trial first if you want to test it first, it's available on the project site.


How do I have anonymous notifications (phone, text, ...) on Android 4.3 like 4.1?

This is only a partial answer to my question, so I won't mark it as accepted just yet.

If you go to Messages / Menu button / Settings / Notification settings there should be a setting called "Preview message". Uncheck this and text messages will not show up in your lock screen.

I have not figured out how to do this for calls though.


How to get spoken instructions from Google Maps while bicycling?

One of these solutions may help, assuming muting Volume is not the cause

Download Voice Directions by keeping map open and getting directions

  Sometimes voice directions aren’t downloaded or need to be updated on your phone or tablet. When this happens, you’ll hear a chime instead of voice directions.

Solution for same problem from Maps help

Uninstall and reinstall Maps updates
Ditto for play services
Clear Cache of maps before navigation


No, you can't do that unless you are using some other app for calls that doesn't shows incoming call screen while the phone is locked.
As phone apps are generally set with a  FLAG_SHOW_WHEN_LOCKED flag, which enables them to show incoming call while phone is locked.


Battery Percentage is not working after flashing Xperia E Dual with Nexboost ROM

Battery percentage is weird at times (goes up and down). Battery life is ok, though. There seems to be a problem with the Poseidon Kernel causing this. Hope @UltraGamerHD will fix it sometime in the future.
A lot of people ask about the stock Xperia Themes. Well, they don't work. I already changed .pngs files in various apks causing the themes to no longer work.
Some apps force closes at times (Whatsapps, Gmail, Browser,etc..). Clearing the apps data, they'll work again.

They did not mention anything about FM Radio.

So the main point is you should wait until they release their next ROM (or) flash another ROM better than this.


Can a malicious application running in a container root the Android?

Guest Users cannot root the phone separately from the main user. If a phone is rooted it is rooted for all users. If your Recovery is not password protected anyone can easily flash Magisk and get root access on his Guest Accout. If the recovery is PW protected it will just take a few more minutes to flash the recovery again/a new one which won't have a password then. That's the big disadvantage of having an unlocked bootloader. The only way to prevent Guests from getting root access to your phone is to install MagiskManager and disactivate root access for Guest-Accounts. I don't know if this also work if the Manager is installed before rooting. If not you need to root your device first obviously.

Or just don't give your phone to someone who would root it to get access to your data or whatever lol


How to completely clear my device of a particular company's apps?

The easiest way is through the web for Google Play. Using the seach bar, bring up the name of one of the suspected apps like Clean Master or any of the apps listed in the article like Kika. Using this page, click the hyperlink for the COMPANY, below the appname. This will bring up all apps for that company, and the card for each app that you have installed will have a green check mark in the bottom right of the card. Selecting in this fashion allows the user some confidence that all his apps from that specific company can be identified. Unfortunately, while the specific app card yields a pseudo-button "Installed", it does not allow uninstall or disable via the web interface. Using the list however, the user would search out, uninstall (or disable) the now-exposed apps directly from the device.

Settings > Apps > <selected app> > Uninstall or Disable


Just wanted to update this in case anyone else cares.

This and many other streaming audio issues seem fixed in the latest OTA:  3.70.651.1


Contact still visible in Whatsapp after deleting out of my contactlist from my phone

According to WhatsApp's FAQ, you may need to refresh the list.  You also will still see the deleted contact if there are past chats you've had with that contact.

  How do I delete a contact?

  The contacts that you see in WhatsApp come from your address book.
  There is no way to directly edit the Select contact screen.

  To delete a contact from the WhatsApp contact list, you will need to
  delete the contact from your phone's address book.

  In order to find the WhatsApp contact in your phone's address book:

  Find the contact in the Select contact page.
  Tap on the contact.
  Then tap on the name at the top.
  On the Contact info page, go to [Menu button] > [View in address book].
  From there you can find the option to delete the contact from your address book.

  Then, refresh your WhatsApp contact list by opening WhatsApp >
  [Compose button] > [Menu button] > [Refresh]

  If you still see the contact, it is likely that you are seeing the
  conversation on your Chats screen. Simply tap and hold on the contact
  and then select [Delete chat] to delete a chat.


Can application upgrades happen automatically, even if you have it turned off in marketplace?

I believe that Google can and will update their system apps like Gmail, Market, Search and Youtube (I think that is still system app).

There have been plenty times that the Market updates itself, without any interaction from the user. I have not seen them actually update anything automatically, except the Market, but if you have a "with Google" phone, I am sure there is some blurb somewhere that says they may update the applications without you knowing, or something.


adb reboot bootloader

then

fastboot flash <whatever-it-is-you-want-to-flash>

If you see  at any point when executing fastboot command, the PC is not configured to use fastboot properly. Most typically, this is because you are not running fastboot with elevated privileges. It may also be that you do not have the drivers correctly installed, which may happen under Windows 8 because of its insistence on signed drivers. - Source


You first have to root your device in order to have root access.
I'd suggest you to have a look here.
Do check for supported devices here [as per devices, samsung galaxy core is supported. Do cross-check whether you own the same model or not]


Go to SETTINGS > WIRELESS > WIFI SETTINGS.

Press MENU > ADVANCED. Ensure the WiFi Sleep Policy is set to NEVER. This will make sure that your WiFi remains always connected. This may however result in a marginal increase in battery consumption.

exclamations mark shown with wifi networks

The exclamation mark on the Wifi sign means that you are connected to the access point but don't have internet connectivity. Ever since Android 5.0, when this happens, it falls back to your mobile data connection. This is probably why the network slows down to a crawl.


Lenovo tab 3 7" TB3-710F Android 5.0.1 won't start after installing wrong TWRP

Thanks for that really detailled answer, dear alecxs.. At first it didnt work because i had the wrong ROM , than i take the correct one , followed the tutorial really exactly from 1-20 and what should i say , i reanimated this Tablet which stucked in a bootloop a long while. Workes well now .. I struggled a little bit with Google Play Services which i cant update  but i kicked them after i rooted the tablet and reinstalled them manually again..

Thanks for this great tutorial


I got it. The permission bits for the font files should be rw-r--r-- . When you copy some file from someplace else to any system folder , check for this pattern in the permission bits and make necessary corrections to do that. It should work.


No fingerprint reader after adding self signed certificate

Step 1: Make the certs compatible (if they are not already)

At the very beginning we need to figure the file name of our the cert file. The name of the cert file is a hash one can obtain from the certificate itself. For this, one needs the openssl tools. On Unix/Linux the steps are then as follows:

# Obtain the hash – in my case that returned d6a2705a – so we have the file name
openssl x509 -inform PEM -subject_hash_old -in root.crt | head -1
# Copy the original file
cat root.crt > d6a2705a.0
# Append additional data
openssl x509 -inform PEM -text -in root.crt -out /dev/null >> d6a2705a.0

Step 2: Get the cert into our system cert chain

If your device is rooted, a solution to this is importing the certificate as system cert (not user-cert). You will need the command line for that, using either adb shell or a terminal app on-device. The following snippet assumes your certificate was already pushed to the SD card, saved as /sdcard/d6a2705a.0 (adjust that to your cert name), and you're at the command prompt of your device.

mount -o remount,rw /system
cp d6a2705a.0 /system/etc/security/cacerts/d6a2705a.0
chown root:root /system/etc/security/cacerts/d6a2705a.0
chmod 0644 /system/etc/security/cacerts/d6a2705a.0
mount -o remount,ro /system

Done. Now you should be able to use the cert – and as you do not have any "unsafe user certs", you're free to use whatever unlock mechanism you prefer.

A quick check shows all these steps are also described in the CaCert Wiki on how to create Android compatible certificate files from their original files. So my personal notes I took the above from might well originate here, at least partly.


Why cant i access my google account on a new phone when I have not factory reset my old phone

You mean that you had to wait 24, and 72 hours to be able to logon again to your google Account. So apparently Google have warn you several times before block your IP (i think).

Concretely, some information is missing in your tracking subject, namely the types of protections you have set up on your Google Account (confirmation email, confirmation SMS, secret key by Google Authentificator, etc).

It also lacks the essential information to know what the exact error message Google is displaying on the screen.

In your security center on your phone connected to your Google Account, do you have any alert related to your problem? This famous Google security center is generally accessible via the phone's settings menu.

In yet another solution, the user has the ability to create special accesses for third-party applications (allow Outlook to access your Gmail account, allow access to your Google account through a Windows Phone).

Maybe you could create a particular access for another type of device, Google will then provide you with an access code, it will want to write it down (without spaces), then enter it as a password to be able to access your Google Account without having you blocked again.

We hope this alternative will help you.


Why Google Play Music app gets turned off when I'm running?

Check your settings within Google Play Music for 'Stream via WiFi Only'. If you have this set, and you're out of range, the streaming cannot continue until you return within range. It may just be coincidental to always appear consistently at that time or range.Also remember about caching. Caching may queue a number of songs, making it appear to extend range.


Any OpenSource SOCKS proxy server for Android?

Use SSH!
You can use the FOSS application SimpleSSHD for this! You can get it directly from that link or using the F-droid app store on your phone.
Once setup you can connect to your device using either your LAN or WAN IP from your PC like this:
ssh -D 8899 <PHONE-IP>

The -D option sets up a local "dynamic" application-level port forwarding, which essentially makes ssh act like a SOCKS5 (SOCKS4 is supported aswell) proxy server.
After this, you can set your proxy to 127.0.0.1:8899 on your PC. I've tested it with curl:
curl --socks5 127.0.0.1:8899 https://myip.is

And it worked! Note that I did not even need root for this, it worked as the normal android user.
Note that if you want to use your mobile network for this your cell provider might not let you connect to SSHD using the WAN IP. A VPN can cirucmvent this if neccessary.


Galaxy Nexus screen flashes and brightness issues on various button taps and screens

I just had this happen to me. Seeing your answer, Moskie, I carefully removed the apps one at a time from the application switcher by sliding them to the right, testing between each one. For me, pressing home from the web browser caused my screen to do a slow flaah, opening the apps menu made it go bright and stay bright.

The app that caused the trouble? Camera.


How to deal with dm-verity on a Samsung S7 Edge when installing a custom recovery like TWRP

For a Galaxy S7 Edge it is possible to root Android 7, and 8. It just apparently takes an engineering bootloader to do so. And I don't even think it is a REAL ENG Bootloader.

I agree with you however, most people in the XDA community that releases anything for a newer-ish samsung device gives little to zero information about what it is their files are even doing to your device.

Like seriously. Chainfire quitted working on Samsung Devices, and now all the big whig samsung devs, WILL NOT divulge their information to other devs.

Because some of the big devs will never own my device, but I can't work on my device because other devs won't share their knowledge, "because if they aren't going to do it, then no one is", apparently.

I had a real eng firmware for the Galaxy Note 5. The same thing they used on the Galaxy S8, but all those same devs laughed at me, and then stole my idea.

I will say JRKRUSE has some good, legit files for you to use on XDA, just don't expect him to explain anything at all. He keeps all his information to himself. Kind of like the S8 devs. Always general information, nothing specific.

But so far TWRP hasn't been officially flashed to a USA Galaxy S7/Edge device. And I think it is because of TWRP itself being so configured for default AOSP Android and not Samsung Android.


Is there a way to change resolution on a Note 4?

If you have root,  you can edit your build.prop file. There even apps from the Play Store to do that for you. When changing LCD density (DPI), be cautious to what you change it to.  Lower the value too much and items will be unreadable, also making the system unstable with certain apps. The Play Store might fail to work. As with everything, perform a backup in case of instabilities.


How to color status bar and navigation bar

You can use this app to set the color of status bar through Accessibility Service :Color Status Bar

(Note: This app runs in background to enable the color.
And, this app will work only on devices running Android 5 or above..)

But to change the color of navigation bar, you need root access.

If your device is rooted, do the following to change navbar color:

Install Xposed Framework and Xposed Installer app.
Install "GravityBox" module (varies for different Android versions) and reboot.
Open GravityBox app, goto Navigation Bar Tweaks
Under Colors section, Enable Navbar Colors and set your desired color.


fastboot is just one of the protocols to talk to the bootloader. Some manufacturers choose to support it (e.g. Google, HTC), others choose to make their bootloaders talk some other protocol (e.g. Samsung).

After googling a little bit, I don’t think that the bootloader of your device supports fastboot (at least, there are no mentions of this). Most likely, you will need a special tool from your manufacturer that will be able to talk to your device in bootloader mode.


Make sure "ok  Google" detection is on for every screen. Do this by opening the Google app, navigate to settings > voice > "ok Google detection" and make sure the "from any sceen" option is enabled. Hopefully this solves your problem.

How do I fully back up an Xperia Z2 phone?

I figured it out eventually. It's not easy, because you need to get root before wiping anything (or unlocking the bootloader, which would wipe everything).

Download a copy of the old firmware, which you can find at the XDA forums. You will need to downgrade to this old firmware so that you can take advantage of an old root exploit (vulnerability). I used version 17.1.2.A.0.314 from the UK, but anything from 4.4.2 should work.
Obtain root and install a custom recovery so that we can use it upgrade the firmware. XZDualRecovery is popular. I used Z2-lockeddualrecovery2.8.21-RELEASE.installer.zip. This includes a root exploit so that it can install the recovery.
You can use the custom recovery (TWRP) to create a backup of the TA partition that includes the DRM keys.
Use the recovery to upgrade back to an up-to-date official firmware version. You need a pre-rooted firmware (PRF) zip file. The best place to look for one is on XDA's Xperia forums. Here's an example for version 23.4.A.1.232. Don't forget to clear the Dalvik cache.

This process does not require you to unlock the bootloader, so the DRM keys are never wiped.


How do I sent an "over-sized" video via my Anrdoid?

The majority of web based email providers have a limit of 10MB for the size of the attachment of every message sent.

Since an email message will often pass through several mail transfer agents to reach the recipient, some or probably all of them impose size limits due to the storage capabilities they have to deal with. This is due to the fact that every message needs to be stored before getting forward.

Applications tend to follow this type of ruling. Although nowadays users tend to use an email like if it was an ftp, thus "forcing" application developers to suppress such limits but given no guaranties that the message will in fact get to its destination.

To resume, you can safely send files up to 10MB between any email providers without the fear of message not being delivered.

My advice to you is the usage of free online services that allow you the transfer or backup of large amount of data between locations:

No payment and no registration:

wetransfer (~2Gb for each transfer)

No payment, just registration: (for the free package)

DropBox
Google Drive
SkyDrive

Android Outlook IMAP: Microsoft account interference in configuration

The problem here turned out to be the specific email address involved (autodetect was working as well as it could given some absent DNS entries; and anyway, as I now realise, autodetect/autodiscover means something different to every email client, and autodiscover specifically is really just an Exchange thing anyway).
I got suspicious once I had tried another email address in the same domain and it worked perfectly.
I had an old Hotmail account set up on the 'phone and tablet for various things (Windows Phone Companion, OneDrive, etc.) This Microsoft account had at one stage included an alias of the offending email address. I had got rid of this alias right at the beginning of this episode, but clearly the 'phone still thought it was there, and in particular Android Outlook was confused by it. Once I had tried on a brand new Android instance (via BlueStacks) and it had worked perfectly, I realised the situation, removed the Hotmail account from the 'phone, and Eureka.


A USB device has a Vendor ID and a Product ID for the host to distinguish a device model. Both are 2-bytes integer. That ro.usb.vid is exactly your device's USB VID. It is located at/sys/class/android_usb/android0/idVendor
Use cat in a terminal to read its value and echo to change it (effective until next boot).
Also you can find your device's USB PID at/sys/class/android_usb/android0/idProduct
which is likely named ro.usb.pid in the same place. Again use cat and echo to access it.

How to access/disable the Google account sync settings in Android 8.1?

You went a little too far! Go into settings -> users and accounts -> Google. Without pressing on your email address, you'll see an option "auto sync account data" turn that off. This will stop sync for all Google apps.

If you just want to turn off sync for some apps, then leave that setting on, and you'll have an option to choose individual settings.

Installing LineageOS OTA update from the recovery manually

If the auto install doesn't work you can go to /data/lineageos_updates and install the update manually.

Remember to wipe dalvik cache after flash ends.

Updated (thanks to Sup3rHugh): LOS changed the OTA folder from /data/data/org.lineageos.update/app_updates to /data/lineageos_updates.


You could use an app locker like Smart App Protector. This will protect your installed applications using a password or pattern.


Transfer Android app with offline data to NEW PHONE without ROOT

You can use adb backup. You can specify the package name for backup a single app (for comprehensive details refer to Nikolay Elenkov)
adb backup [-f <file>] [-apk|-noapk] [-obb|-noobb] [-shared|-noshared] [-all] [-system|nosystem] [-keyvalue|-nokeyvalue] [<packages...>]
adb restore <file>

Note: some apps won't allow adb backup. even if adb backup is allowed, cache is not included.
Find a [GUIDE] How to enable adb backup for any app, decompile, recompile and sign the apk, where you have set the following flags:
android:allowBackup="true"
android:fullBackupOnly="false"

On the source phone, update the apk with your modified one. To do this without uninstalling, this may require to increment the android:versionCode in AndroidManifest.xml, and you must sign the apk using the same original signature that was used previously for the apk from the Play Store. This is the pitfall if you are not the author of the app it is not possible. However, if you manage this the install will succeed without data loss. Otherwise install will be rejected. (You still have the option to set allowBackup directly on rooted phone, but this may be out of scope because with root you can backup app directly) apparently there is no way to override AndroidManifest.xml during runtime
Once you have installed the modified apk you can make a backup of your app from source phone, and restore it to destination phone without root.
Install the latest Platform Tools and run from cmd.exe as Administrator:
adb.exe backup "-f C:\example.ab -apk -obb com.example.package"

edit:

be aware you have compiled a different app that can't be updated via PlayStore anymore

starting with api level 30 modified apk is no longer required as the flag seems ignored

How can I get the Android to use wallpapers sized to my screen resolution?

If I remember correctly, the aspect ratio is always for a 5 desktop scroll. If you have enabled only one desktop, the you'll see just the middle part of the wallpaper.


Android keeps closed applications on memory as long as possible so that when you return to the application it will still be on memory and will load faster than loading from the internal memory or SD card; but if another applications needs memory, unused applications and background applications will be automatically force killed to give way to the foreground activity.

In short, Android is not Windows, don't treat them the same.

You should only force close misbehaving applications, not for freeing memory; without a dedicated task killer, you can do this from Settings > Applications > Manage Applications > *name of application* > Force Stop

Stop certain apps from ever using mobile data

Frankly telling : You just can't stop an app from using the data when it is running in the foreground. Android has not implemented any feature till now. However, You can restrict the background data for the apps and save the data. Better you keep mobile data closed when you're using WiFi. I know its frustrating but that's the best you can do.

 Another option is to use a custom ROM like CM. It has the profile option where you can set the usage of your WiFi and data when you're at your home or office.


How to edit 'etc/hosts' file in non-rooted phone?

Unless I missed something, that is not possible. Without root access only the mechanism of flashing an update (via recovery or OTA) can modify /system. To be accepted, such an update archive must be signed with the same key as the ROM – which is something only the developer of the ROM (here: the LOS team) can do.

There might be a way via a custom recovery which lets you edit all file systems directly (see e.g. twrp). But without knowing what device it is, it cannot be said if a matching recovery exists (you can check that in the Devices section of their website for official images, and search XDA for unofficial ones). Apart from that, it's either rooting the device or not editing any file within /system.

i have lost my images by deleting them but now i want them back

I've done this before and this is how I got them back:

First things first:  STOP using your phone as much as possible, specifically you don't want to do anything that may overwrite the area where your pictures are.  When you "delete" something, the memory where it is stored is marked as free to be overwritten by other data.  Until this happens you can recover them because they are still there, just waiting to be overwritten by other data.

Here is what I did:

I did a search and found some free file recovery software for my laptop.  I'm not sure what program I used, but there are plenty that can be found for free if you look.  Maybe someone else has some advice on this part?  In fact, many of these programs can be run off a USB stick and may not even need to be installed.  Just search around.
Using your phones USB cable, plug it in to your/a PC where your deleted file recovery software is installed. Mount the SD card, assuming that is where your photos were stored.  If not then just make sure you have access to your phones internal storage from your PC.
Point your file recovery software to your phone/sd card and start it running.  It should find all your pics, and probably a bunch of other stuff.

This type of software usually allows you to pick the location you want it to check as well as a time frame so you can search files deleted in the last 24 hours, last week, or last month etc.  Depending on the software you download there could be other options such as file types to look for.

If you are a Mac user I'm fairly certain this would work the same way, although I've never tried it with my Mac.

Good Luck!  This saved my kids Christmas pictures and about 1200 other ones last year when I accidentally deleted them, so I hope you have a similar experience.


Nook simple touch screensaver in USB mode

Whenever you connect your Nook in USB mode your USB storage from Nook gets unmounted and mounts in your computer. After its unmounted the OS can no longer find your screensaver. That's why Android doesn't want you to keep widgets in USB storage. Similarly apps moved to USB storage no longer works while connected to your computer.

If you move the screensaver to internal partition then it will work even when mounted to computer. For this your Nook must be rooted.


I was having that problem until I turned on Save Location, then the time stamp became exactly the right time.


Android supports the RTSP protocol (I believe using VideoView), I'm not sure if this has everything you're looking for.


What is the difference between Ultra pixel and Mega Pixel camara?

Extracted from UltraPixel vs Megapixel: HTC One & iPhone 5 Camera Shoot-Out:
Ultra-Pixels:

Basically the sensor on the HTC One features larger pixels for better low light sensitivity and, on paper, better overall camera performance.
[...]
We have to understand that “ultrapixel” is just HTC’s marketing team saying that the pixels on the HTC One’s sensor are larger. Here’s how it works: the sensor on the HTC One isn’t larger than the sensors on other modern phones: 1/3.2-inch is what HTC used in the One and the same size is also present on the iPhone 5, Galaxy S III, or Lumia 920. A larger sensor means having something like the Nokia 808 PureView has with its 1/1.2 inch sensor.

Some other site described that term as "plain market buzz". More on the term UltraPixel can also be found at Wikipedia.
Megapixel, on the other hand, is a measurement term, describing the resolution of an image – a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.

replace native samsung galaxy s3 email app for gmail app?

Summary of comments, as requested by the OP:

If your device is running Android 4.x, you can simply go to Settings → Applications → Manage Applications, scroll to the app, oben its entry, and hit the "Disable" button -- et voila, it's "gone", and will no longer appear in any other place. If you need it again at a later point, it will still be at the end of the list, so you can enable it again.

Note though, that some manufacturers / ROM builders decided to preventing some apps from being disabled. Nothing you can do in that case without root. If you rooted your device, on the other hand, apps like e.g. Titanium Backup ★ root would let you freeze those apps as well.

Note also GAThrawn's comment: If you don't configure the email app, it won't run. Some homescreen replacements (aka "launchers") allow you to hide unwanted apps from the app drawer (e.g. GO Launcher EX), so you at least can ban them in some way.


Can I share my Google Play "cloud" music with a family member?

Any music you purchase via Google Play Store or upload via Google Music Manager application is tied to whichever Google account you selected within the app under Menu -> Settings -> Google Play account.  Starting with Android 2.2 (a.k.a. Froyo) you can add multiple Google accounts on Android devices (phones, tablets, Google TVs, etc.)  Therefore if your relatives' handset/tablet supports multiple Google accounts, you can add your own account under Settings -> Accounts & sync on their device, and then within their Play Music app's settings you should be able to change the account to yours.  The music should then be available on their device to stream/download.

Go to Settings, Language & input, Google or Android keyboard settings then untick the box next to "Sound on keypress".


My Android (Samsung Note 4) keeps disconnected after a while from a sign-in required wi-fi

I've searched and it seems this problem is not related to VPN. It's a capabilyty/Bug [at least] in some android devices (esp Samsung) which turn off the wifi when it found it not connected (without considering the simple fact that it might have connected through a vpn!). So this is a Bug. It seems this helps somehow.

In a nutshell current solutions are these:

Block client3.google.com in your router
Fool your device by setting up face proxy (then the sign-in required message goes away) and then modify it to none proxy again
disable wifi assisted location


Search result scrolling / paging on Android Market?

When you scroll to thr bottom of the list it should automatically load more results. Mine sometimes gets hung up and shows the "thinking" symbol for a few seconds, but then loads more.


Are you using make -j# otapackage? If so it should result in a ZIP that should flash with no problems.
Also fastboot format all partitions to get rid of the decrypt error.
If the source is untouched, i.e. the ROM compiled is the same as the stock ROM, the images should flash without any such error.


android 2.2 - extending phone storage to SD

You can move any apps to sdcard if you are rooted. There are apps on the Market for it Move2SD Enabler and App Swap

Better yet, if you are using custom ROMs (e.g. CyanogenMod), some of them have settings to allow you to migrate any apps. You might want to check those out first if you're using custom ROM.

If you want to do it manually (not recommended for pregnant man, or those currently having a heart attack), then you can use Terminal Emulator or ADB to run a few fairly standard set of Linux/Unix commands. The mount command can rebind any folder in your filesystem another location in the filesystem. Alternatively, you may also create symbolic links using the ln command. See the mount and ln manual for this.


Lollipop - mute notifications but not calls

It can't be done. https://code.google.com/p/android/issues/detail?id=79445

This is currently a very hot topic with many people extremely frustrated that this functionality has been removed. Hopefully google will bring it back.


I had a similar incidence, in my case i left a service open. Please check if any service related, is open ?

To check you can use,

This is a known "bug" with Android (it is probably intended behavior).  The language, locale, and related settings are all linked and cannot be changed independently.  Google apparently decided that people who read Italian want to see numbers for dates.  I don't believe this was changed in 2.3-gingerbread so I guess there is no fix yet :(
