File transfer between Android 6.0 and Windows 7
I updated my Nexus 5 phone to Android 6.0. After this, I have file sync problem between Android 6.0 and Windows 7.

I transferred files from Windows to Android Internal storage\Download using USB MTP, then I can see and open the files in Android phone, but cannot see them in Internal storage\Download from Windows explorer. I deleted an old file from Android phone, but Windows still gets old list of Internal storage\Download.

Even worse, my old photos in the phone cannot be transferred to computer via USB. They do not show up in computers in either Mediafile Transfer mode or Photo transfer mode. Only new photos after update can be shown and transferred.

Issues with limited internet connectivity (photos, wifi)
There are a host of issues that you run into when running stock Android in a country that blocks Google's servers. The first issue you run into is the setup wizard getting stuck trying to do updates. I already found a workaround for that one. But I can't figure out how to fix the following:

Wi-fi connections always show "Connected, no Internet" with an exclamation point icon.

Doesn't automatically connect to saved wi-fi locations because it thinks there is no Internet.

Photos app doesn't show any photos at all except when Airplane mode is on or when connected to a VPN.

Other issues such as the Play store not working are to be expected. But I wish I had workarounds for the 3 issues above. The "Connected, no Internet" warning must be using some Google service to detect connectivity. Can it be changed to use some other service that is not blocked? The Photos app not showing photos seems an unexcusable offense because the photos are stored locally and browsable with a file explorer. Why does Google need to go online at all to display photos on the phone?

Music stream interrupted by Facebook likes
Today my OnePlus One (Android 5.0.1-BlissPop) doesn't work as expected. Usually, I surf on Facebook (using the app, not by browser) and at the same time, I listen to some music with the player Shuttle (regularly available on the Play Store).

This morning, every time I press the "like" button, music stream get interrupted for one second, like the button pressing action override the music stream with another one not well defined.

How can I solve this?

Other SIM cards won't work in VZW S5. Should I root it?
I have a Verizon S5 which they claim to be unlocked. I travel internationally a lot and Verizon doesn't cover some of the places I go, so the Verizon rep I talked to said it's fine to just change out the SIM for a local one. I tried this in one country and it wouldn't recognize any local networks (or let me access the network selection menu for that matter). During my most recent trip back to the States I purchased a pre-paid T-Mobile SIM because it allegedly does work in these countries. However, upon installing the SIM I found that I only had voice/SMS capability (no data) and as soon as I left the US it stopped working entirely. The T-Mobile support couldn't even figure out what the issue was.

I have a sneaking suspicion that if I root the phone to get rid of the Verizon controls on it that it will magically start accepting other SIM cards. Unfortunately I have no references to back up that suspicion. Can anyone confirm whether or not that would help my situation?

How to set default home screen on Android 4.4.4

问:
Nexus 6 no longer turns on, now that I have flashed a Marshmallow ROM + bootloader
I have a Google Nexus 6 (Telus/AT&T) and I had been successfully running the Lollipop version of Chroma for months now.

Yesterday I flashed Chroma Marshmallow ROM, and the recommended Google Apps, along with the MRA58K bootloader. Everything went well and I successfully booted into the ROM. After my apps were restored, I rebooted the phone and everything worked just fine.

This morning, I used Titanium Backup to restore my back up of Adblock. After it restored successfully, it prompted me to reboot. Then the phone shut down and I haven't been able to turn the phone on. I am not even able to get into recovery.

Not quite sure what has happened here. The phone rebooted successfully several times since the successful flash. I have had my Nexus 6 charging for quite a while now with the stock USB cable and adapter and still nothing.

When I plug my phone in to my Win10 PC via the USB cable, I get nothing (it would register before).

Is this a sign of flashing the incorrect bootloader? How can I tell what is actually wrong? Is my phone bricked?

I have checked the Chroma thread and even made an XDA post requesting assistance. But there have been no leads so far.

Edit to answer @unforgettableid questions;

When you charge your phone, does any LED light up?

No, no LED lights up. Mind you, no LEDs would light light up on a stock Nexus 6 anyhow.

When you hold down your phone's power button for ten or fifteen seconds, what happens? Does the phone vibrate (signalling that it's getting ready to boot up?) Does the screen's backlight turn on? What do you see, hear, and feel?

Absolutely nothing happens. No vibration, no back light. It is like the battery is dead, however it has been charging for well over an hour now using stock cable and adapter (plugged into AC)

[2015-11-10] Edit to answer additional @unforgettableid questions;

Please plug a battery (which is not full) into the phone.

Can the phone successfully charge the battery? Does any voltage travel between the phone and the battery?

Not sure how to plug in a battery to the phone. The battery in the Nexus6 cannot be removed.

Do you happen to own a clamp ammeter?

I do not.

Do you happen to have access to a thermal-imaging camera?

No.

Do you happen to have access to a JTAG box?

No.

Does your phone have JTAG pins? 8. How hard are they to access?

Not 100% sure, but it sounds like you shouldn't need to go that route with a Nexus 6.

Please boot up Linux. Enter lsusb. What do you see? Enter dmesg. What do you see?

How to perform emergency call while "Android is starting..."
Sometimes when I start my phone I get this "Optimizing app" thing that takes about 10 - 20 minutes for it to finish.

During this operation phone is unusable and reset doesn't help as the operation is repeated on next boot.

I am wondering, sometimes my nexus dies because of low battery. Now imagine there was a car accident and I needed to do emergency call. I could start it up using USB charger I have in my car, but what would I do if it got stuck because of this "Optimizing" thing?

Keyboard settings crashes at post-reset setup, can't access phone
I rooted my device and everything went fine (Kingo Root automatic app). Some time after making my first steps into the rooted device, I tried a "Reboot menu" widget, a window with options popped out and I clicked on "Bootloader" and the phone restarted (I have no custom recovery) and went to pin input then home screen and everything felt fine until I tried to search something and the keyboard didn't appear. Went in Settings, then Language and Input, and the app crashed leaving a "Settings app has stopped." message. I tried another keyboard to substitute but nothing happened (still could not access keyboard settings).
I saw after that on a forum that a guy fixed all of this by factory resetting his phone so I tried it, and now I'm supposed to be at the setup page (like the first time you boot) and as always first thing to set is Input, and as the whole keyboard settings is bugged, I constantly get a warning "Settings has stopped working" and click on OK and it reappears.
Pretty much can't access anything on my phone.
Is there a way to prevent Settings app from further crashing from within a PC connected to the phone?
Or completely resetting the phone? Data is of no concern, I just want my keyboard working again.

P.S. Have I done something to the android keyboard? (maybe deleted it by bootloading? unaware though..) Maybe I have to completely wipe and reinstall settings app? Being a newbie, how can I do all this?
Thanks in advance, any help appreciated

Samsung Galaxy S6 - Files being deleted
On my Android phones I have always used a folder with a .nomedia file in combination with QuickPic to store password protected pictures.

I've recently got a new Galaxy S6 and have continued with this. I plug my phone into my Windows 7 PC via USB, created the folder with .nomedia file in and copied my pictures over. I then go into Quickpic, choose 'Show Hidden' and my pictures show. All good.

However, coming back some time later, I go to Quickpic and do the same, and nothing shows. Plugging back into PC via USB and the folder itself is no longer present.

The first time this happened, I had had the phone about 10 days and the files had been there, but then suddenly they were not. Yesterday I readded some files and they were present - however coming back less than 24 hours later, they have gone again.

I've read some questions that sound similar, but the general case is that people have a .nomedia file by accident. I don't, and have been using this method for several years without issues. The files are literally not there any more, not showing within android file system or when attached to PC via USB.

Restarting makes no difference, but again, why would it when the files have been physically deleted.

So, what is deleting my files?

Display wouldn't turn on without a restart (Galaxy Note 10.1 2014)
The device is working great until it gets locked (by single power button click). So when I lock it, it just wouldn't turn on, the buttons are working though and it seems it's still running it just showing a black screen.

Interestingly if I try to change brightness it wouldn't respond. Looks like these two related issues.

So to turn on I am having to restart the device and make sure it is awake

So factory reset didn't help (erase all data).

How to make marshmallow obey `ro.secure=0`
I'm using a Nexus 5X with release 6.0.0 (MDB08M).  I unlocked the bootloader with fastboot oem unlock, then created a boot image with a /default.prop file containing ro.secure=0.  This appears to work, in that when I boot my device, I get:

```<code>shell@bullhead:/ $ getprop ro.secure
0
</code>```

Unfortunately, though adb root seems to succeed and reports:

```<code>restarting adbd as root
</code>```

It does not get me a root shell.  ps confirms adbd is still running as the shell user.  My question is how to make adbd obey ro.secure, or whether there is some other easy way to get root by modifying /default.prop or changing the kernel command-line arguments.  I know there are third-party tools such as SuperSU, but I'm hoping to get a root shell without loading any third-party software on my phone.

To reproduce what I did, you can grab boot.img out of the Nexus factory image (unzipping image-bullhead-mdb08m.zip).  Unpack the boot image using split_bootimg_pl.  Unpack and repack boot.img-ramdisk.gz (I packed it using find . | bsdcpio -R 0:0 -H newc -o |gzip -9 > ../newramfs.gz).  Create a new-boot.img using mkbootimg as follows:

```<code>mkbootimg -o new-boot.img --pagesize 4096 --base 0 --kernel_offset 0x8000 --ramdisk_offset 0x2000000 --tags_offset 0x1e00000 --kernel boot.img-kernel --ramdisk boot.img-ramdisk.gz --cmdline "console=ttyHSL0,115200,n8 androidboot.hardware=bullhead boot_cpus=0-5 lpm_levels.sleep_disabled=1 msm_poweroff.download_mode=0"
</code>```

And finally of course flash new-boot.img with fastboot flash boot new-boot.img.

S6 EDGE Android USB drivers
I'm trying for two days to find a solution for this problem. None of my researches have been successful. I tried Intel Android drivers, uninstalled from SDK Manager and re-installed Google USB drivers, changed MTP to media option, used stay awake screen option, and tried to manually install drivers.

I changed the fast charge cable with a standard one and the connect/disconnect cycle stopped suddenly. But Android Studio still doesn't recognize my phone.

How do I make my phone sync to UTC, not GPS time?
I recently discovered that my phone's time was 17 seconds fast.  After some digging, I discovered that GPS time is 17 seconds ahead of UTC, due to not having leap seconds.

In my phone, I have selected the time to be set automatically via "Use network provided values".

How can I disable "Clear recent apps"?
I have never wanted to clear the apps from the recent apps list but this has happened to me numerous times. At first, I thought it was a bug that happened randomly. Then I found that just above the menu button on the screen is another button that clears all the apps. I have accidentally hit this when trying to switch between apps many times because the two buttons are so close to each other. It just happened again when my cat rubbed on my hand and the phone as I was using it, and managed to press menu/clear recent apps with his face.

I would accept instructions on any of the following as an answer:

Remove the Clear Recent Apps button

Move the Clear Recent Apps button somewhere harder to press

Add a "confirm" dialogue to Clear Recent Apps

Block the action within the OS

I'm currently using Android 5.0 and my phone isn't rooted.

The button is the one on the semi-transparent overlay at the bottom with a "menu" icon with a superimposed cross.

How can I get rid of emulated External SD storage, to allow using a real SD?
I have a Visual Land Prestige Elite 10Q tablet (KitKat 4.4.2, rooted with KingRoot), and have discovered that even after rooting and using a utility to "fix" the SD to be writable from KitKat, I can't move applications to the SD using X-Plore or App2SD, though I can now write files and create folders there.

Based on the error messages I've received from App2SD, this appears to be due to the manufacturer of my tablet having created an emulated external SD using dynamically allocated space in the internal storage (16 GB, so I'm not short on storage yet, at least).  I believe that if I can get rid of this internal_sd storage, move its contents to external_sd, and change the appropriate OS settings so it looks for external_sd, I'll be able to move/install apps to SD.

There don't seem to be any specific ROMs for this device, so flashing to Lollipop or Marshmallow is risky -- I'd prefer to get KitKat to behave, if possible, though I'll consider forcing an upgrade if I must.  I also don't have dozens of hours to spend fooling with this thing.

So, the real question: how can I convince the device to ignore or delete the internal_sd and use external_sd instead?

Update: I've installed a root terminal app, and appear to have access (as su) to the root file system, but I don't find /system/etc/vold.fstab.

Replicating features of Doze mode using other tools/apps
target android version: 4.2.2

Doze mode is one of the new features of Android 6.0 Marshmallow; In the documentation it is said that:

The following restrictions apply to your apps while in Doze:

```<code>Network access is suspended.
The system ignores wake locks.
Standard AlarmManager alarms (including setExact() and setWindow()) are deferred to the next maintenance window.
If you need to set alarms that fire while in Doze, use setAndAllowWhileIdle() or setExactAndAllowWhileIdle().
Alarms set with setAlarmClock() continue to fire normally — the system exits Doze shortly before those alarms fire.
The system does not perform Wi-Fi scans.
The system does not allow sync adapters to run.
The system does not allow JobScheduler to run.
</code>```

My question is how we can create Doze mode behavior by tools like Amplify, Greenify or other available tools?

For example how we can create a condition that in which the system ignores wake locks? (What tool/app? what config?)

Samsung Galaxy S2 (i9100) stuck @boot & unable to flash
Nearly three years ago my Samsung Galaxy S2 (i9100) system completely broke (after about 1 or 1.5 years of what I would call normal Samsung usage :D - a lot of errors and problems, but usually fixable) and wasn't bootable any more and I decided to install CyanogenMod. After some struggling I was able to flash it correctly via heimdall (on Linux) and used it for more than a year afterwards.

At some point it suddenly stuck at the Samsung boot logo (I can't tell any more if there was a specific reason) and I was really stressed by my job so I had little time to repair it. I bought an HTC and still am very happy with that. Sadly, my brother is in big need of a replacement for his damaged phone so I am trying to repair the Samsung.

I found out that it does not only hang on the boot logo, but also is not able to boot into Recovery Mode by pressing (in that and any other order) [Vol-Up]+[Home]+[Power]. I am able to boot it into Download Mode by pressing [Vol-Down]+[Home]+[Power] though, so I decided to simply try and flash a current CyanogenMod kernel following the CyanogenMod Guide for my device. Neither the latest of the Snapshot nor the latest of the Nightly releases and not even an allegedly official 4.0.3 ROM are working, though.

All kernel uploads hang at ~30MB (cm-12.1-20151114-NIGHTLY-i9100.zip with a size of 232252K @13%, cm-11-20141115-SNAPSHOT-M12-i9100.zip with a size of 210012K @14% and I9100XXLPQ_I9100OXALPQ_XEO.zip with a size of 391632K @7%) and the heimdall command respectively breaks after quite exactly 10 minutes of hanging at that percentage. The output is always something like this:

```<code>root@debian:/home/david/Desktop# heimdall flash --KERNEL cm-11-20141115-SNAPSHOT-M12-i9100.zip --no-reboot

I downloaded the latest ClockWorkMod Recovery from here and tried to flash it, but the result did only slightly change from hanging at ~30MB to hangig at 100% (the clockworkmodrecovery.6050.i9100.touch.img I tried to flash having a size of 5024K). The process is pretty much the same by any other account:

问:
What is the Android system update process like?
I cannot find any information on this when I search for it, so I figured I would ask here. I'm curious about the process by which an Android device is updated. Are system updates written to a location in the internal memory that the bootloader reads them from? Or does the kernel overwrite the boot and system partitions while running in RAM? How are downgrades prevented from occurring? By way of a counter that is stored somewhere in the internal memory?</p>

Why does Chrome open links from wonderlandads.com on scrolling?
I have been seeing this problem for a long time in my Android mobile devices and laptop Chrome browser.

When I try to scroll down a page, the browser just hangs for a microsecond and then automatically opens a link (wonderlandads.com/...php)

This wonderlandads tab has random ads in case of laptop, and in case of mobile it says virus detected!

Anybody has any idea how to deal with this?

P.S.:- I googled about overcoming this but did not find any related problem. So I am curious to know whether this issue is related to my Google account and spreads itself on devices where I open my Google account, or is this a Google bug/some sort of virus? I have tried uninstalling all the Chrome extensions.

Camera keeps crashing on Google Nexus 5 with 6.0 Marshmallow
I have a Google Nexus 5 with Kernel 3.4.0-g2aa165e and build number MRA58N. (Android 6 Marshmallow)

Just recently the camera keeps crashing. I click the camera button and get "can't connect to camera" message. The only way to start up the camera is to switch it off and on again. I'm travelling and take a lot of photos - Its incredibly frustrating when I just want to take a quick snap. By the time the camera comes back on, the moment has passed.

问:
Parental lock: use parental lock app on my profile, or use restricted profile, or use full account with parental lock app?
I want to use a single tablet for myself and the kids: 1 adult, a 6-year-old, and a 3-year-old. But whichever path I choose, I seem to run into problems. This is the only really related topic I found on this entire site, and it's 2½ years old and doesn't help me.

I have googled a lot but couldn't find a good resource to address this, so I'll try to summarize my options below. TLDR: What's the "best practice" for child-proofing a shared family tablet?

--> Which of these options is "best"? (use your personal interpretation of "good")

option 1: use my own profile + parental lock app

The tablet runs with my Google Account. I use this with many of my own apps and I certainly don't want the kids to mess with any of my apps. I installed the excellent parental-lock app "Kids Place" as well as a scheduler plugin to limit the time per day it will run.

Pros:

I can set up both kids inside the lock app, no further Android user accounts necessary.

I only need to install each app once.

I only need to pay for each app once!

The parental-lock app linked above is really sensible! (In particular: daily time limit, app selection, lock down the system)

Cons:

App data (game progress!) is shared among both kids and myself.

option 2: use restricted profile for each child

Pros:

Simple; no parental-lock app required.

Separate app data (game progress) for each profile.

Cons:

Restricted profiles are not good enough! Too many settings and features remain exposed. The entire "Settings" remains available, as well as lots of system things like Google Now. No time limiting available!

I need to install each app in each profile.

I need to pay for each app in each profile! WTF??

I can't turn a restricted profile into a full profile later on (when they grow old enough); would have to delete the profile and reinstall desired apps (losing all data).

option 3: use full profile for each child + parental lock app

Pros:

The parental-lock app linked above is really sensible!

Separate app data (game progress).

I can remove the parental-lock app, and they'll have a full account. Easy.

Cons:

I need to set up each kid's settings in their respective profile. Twice the work!

I need to install each app in each profile. Twice the work!

I need to pay for each app in each profile! (again, WTF??)

Most glaringly, I don't want to pay for any app several times over especially when it's all on the same device. And while Google's built-in restrictions are a good first step, they're really not enough. As I said, I can't believe nobody has asked or blogged about this yet - it must be a common challenge for parents?

No, I don't want to purchase a separate tablet for each person in the household. Even if I'd want to spend the money, I'd still be faced with most of the drawbacks listed above (but then it would make some sense to buy the same app several times; once per device).

So far, I'm going with option 1 simply because it's the least trouble and the drawback is the least painful to deal with. But I'm not happy with it - call me a perfectionist :-)

Update 2016-05-27:

As noted, I chose option 1, and it has served me fine. The tablet is locked with a pin code, and the parental lock app is also locked with a pin code. This works very reliably, and is really easy to handle. The one contra argument I listed still seems to be the only one, and it's not a real problem.

Incidentally, as it turns out, the tablet in question gets used very rarely - good thing we got a cheap one!


问:
Create burnable image of Android?
I'm using a tool to flash an Android device with a .img file.  The tool is called USB Flash Burner.  What this tool does is you boot the Android device up while pressing a paperclip in the reset button.  Then you point the USB Burner Tool to an .img file and it writes over pretty much everything.  Here are the instructions.

If you want to use the Amlogic USB Burning tools to update, please download the firmware here:

http://pan.baidu.com/s/1mgl3R40

firmware update instruction for update via usb buring tool is here:

http://blog.geekbuying.com/index.php/2014/11/24/how-to-flash-stock-firmware-on-mk808b-plus-quad-core-tv-stick/
  please note, you should use the newest usb burning tool, download it here:
  http://www.mediafire.com/download/zo7b5cy0nzb7o91/Amlogic_USB_Burning_Tool_New_Version.rar

If you want to use SD card to do the update, please download the firmware here:
  http://pan.baidu.com/s/18OSRc
  password: 9qca

Now my questions is how do I make my own .img file that I can use with the USB Burner Tool?  Is the file that I burn using the USB Burner Tool a ROM?  Firmware?  And how do I go about creating the .img file needed?  I need to make my own because I have to make a version that I can flash for other people.  The devices of the other people are all exactly the same.

I already used TWRP to make a backup, and it give me boot.emmc.win, data.ext4.win, data.info, system.ext4.win, and system.info.  This works but I have to insert the sd card in and press a bunch of buttons to make the recovery work.  We deal with a lot of devices and with the USB Burner Tool it is faster and brings the device back if it is really bricked.

Thanks for any help!  Also if you have pointers to help that would be appreciated about where I can look.

How do I set up my Sprint Samsung Galaxy Note 5 as a hotspot for free?
I've tried downloading several apps from the app store but they do one of two things; they either hang and don't work, or they bring up the phone's hotspot screen and ask me to pay for the service.

I am trying to avoid paying for an additional metered data plan from Sprint. I already pay them $125 a month for just this one phone and service.

There's a guy who has a video on youtube on how to do it, but you have to pay him for the info and I fear I'll have to root the phone.

I'd prefer not to root the phone.

I'd like to be able to share the 4G LTE Internet connection with my laptop. My laptop is a Samsung NP900 ultrabook.

I have an unrooted 64GB, Galaxy Note 5 on the Sprint system in the United States:

Android version: 5.1.1
Model number: SM-920P
Software Version: N920PVPU2AOJ6
Hardware Version N920PO3

Phone not reading headphone jack resistance
So I wanted to modify a pair of headphones I have to work with my android phone (Motorola Droid Turbo), and to do so I was experimenting with resistor values according to the "Wired Audio Headset Specification (v1.1)"

https://source.android.com/devices/accessories/headset/specification.html

I wired up a 240 ohm and 470 ohm resistances which should control volume up and volume down, respectively. I plugged in an old headphone jack I spliced, and double checked the voltage output which was reading the correct 2.2 V. Unfortunately when I tried connecting the 240 ohm and 470 ohm across nothing happened. I tried this with my friend's android phone (LG G3) and it worked perfectly. Not really sure where to proceed from here.

Certificate Authority installation doesn't work
I've seen many many posts* lined to my problem, although none of them seems to refer to my bug.
I set up my small PKI (for Web, mail etc.) and now try to import my CA .crt file to my Android device. Each time I try to open the cert file I am prompted for entering a name for the imported CA. I then validate the name and the purpose (VPN and applications) and a small Pop-up appears "MyCA has been imported."
However, when I go to Preferences > Security > Trusted certificates > User certificates, my CA doesn't appear.

I tried to download it :

via Web (URL pointing directly to the .crt file encoded in PEM)

with the file (uploaded to Downloads/ folder, then Import from SD > Internal, same behavior)

via ADB to the added-certs/ folder (access restrictions indeed)

Does someone have an idea ?

Storage cannot be found from apps, folder /storage/emulated missing
I installed a custom ROM (CM 12.1, based on Android 5.1.1) on my Galaxy S2 (GT-I9100). Also, I repartitioned the storage using this PIT file: I9100_2.0GB_Sys-05GB_Data-023MB_Preload.

All but the access to the memory (internal and external storage) works fine. Unfortunately it is not possible to write or detect both storage points. The consequence is that apps like the camera, or downloading any content do not work. If I remove the SD card from slot most of these app crashes or display an error message.

However, the SD card is not damaged. I already used it for installing the ROM and it is detected inside the file manager (/storage/sdcard1). Inside the file manager I can create or delete files and folders, too.

The problem seems to be a missing mount point that links to the internal storage. Comparing this device with another device with CM the following folders are missing:

/storage/emulated

/storage/emulated/0

/storage/emulated/legacy

These folders are empty (it should contain a folder Android):

/sdcard

/storage/sdcard0

/mnt/sdcard

The folders and mount points for the external storage (SD card) exist but apps (except the file browser) cannot use them. These are folders that seems to be correct:

/extSdCard

/storage/sdcard1

In my opinion a shortcut to internal storage ist wrong or missing. Do you have any idea how I can fix the issue? Thanks a lot.

Whatsapp encryption key location
I have an old phone (Galaxy S3 international unbrandedand) and I would like to decrypt my whatsapp backup files (crypt8, as recent as the latest backup which is always at 4 AM, I think).
I've googled many tutorials but they all seem to be outdated.
Most of them presume that the key file is located in /data/data/com.whatsapp/, however this folder does not exist on my phone.
I've also tried adb backup as root on my linux laptop (adb backup -f whatsapp.ab -noapk com.whatsapp), but when I transform this ab file into a tar and then extract its contents, it's just empty.
I've also tried to locate the com.whatsapp folder (not the user files folder with the actual *.crypt8 files, pictures, etc), but I can't find it anywhere on my phone.

Am I missing something? Are the whatsapp app files somewhere else now? Or has the location of whatsapp changed?

Custom notification sound for particular Hangout keeps reverting
On my stock, unrooted Samsung Galaxy S3 running Android 4.4.2, with Hangouts version 6.0.107278502 set as my default SMS app, I have the following settings (only giving you those I deem potentially relevant):

General Settings

Enable merged conversations: yes

SMS

SMS account: (my gmail)

Send SMS from: Carrier number

SMS sound: Flowers

Account Settings

Notifications

Hangouts messages & invites

Notifications: yes

Sound: Hangouts Message

Vibrate: yes

Google Voice SMS

Sound: Hangouts Message

Vibrate: yes

Additionally, I have set custom sounds under People & options for three conversations. One is for 40404, the short-code for texts from Twitter; which is set to:

Chat message sound: Chirps

This is so that I can ignore that particular notification if I'm even remotely busy, since Twitter messages are generally less important than a text from a friend.

Another is for another short-code, this one for deals from a local pizza place:

Chat message sound: Good news

The only other custom sound I have set is for my wife, so I can make sure I always read her messages, even I'm in an important meeting; her message could be even more important. For her, I chose the sound I found to be easiest to hear when the phone is in my pocket, yet not an annoying sound to hear often if I should receive many messages in a short timespan:

Chat message sound: Pure bell

While this conversation history does include some SMS (and possibly also MMS) messages, our standard practice is to use Hangouts messages between each other.

The problem is, every so often (on average, two or three times per week), my wife's notification sound spontaneously changes to Chirps, causing me to miss her messages because I think "that's just Twitter". If I open up the Hangout and go into People & options, the sound setting has been changed. I change it back, and it takes effect, but eventually it reverts back to Chirps again.

One time I actually "observed" the change as it happened: I was actively using the Hangouts app, and had exchanged messages with my wife within the last few minutes. As I was looking at my conversation list, the screen blanked, and then the splash screen appeared, along with a toast notification "Signed in as d***@gmail.com" - apparently Hangouts had crashed and restarted itself. When the next message arrived from my wife a few moments later, it played the Chirps sound.

The change coincided with Hangouts experiencing some kind of crash! On that one occasion, anyway.

My question is:

Why is this happening, why only for this one Hangout and not for any others, why does it always change to Chirps (i.e., why not the default sound of Flowers or Hangouts message), and, most importantly, how can I prevent it from continuing to happen?

I'll accept any answer that fulfills the last part of the question; the rest would be interesting information, but should be considered optional.

bad calls on custom rom on I9500
For quite some time of trying out various roms on my I9500, I've found out that on all of them I had a call issue, where the other person kept hearing himself twice (echo).
I've tried today to flash a modem for it, but for some reason, now it doesn't identify the sim card anymore.

I've tried flashing other roms, including wiping of everything except for internal&external storage, of course.

The sim card itself is fine, as I can see it working well on Nexus 5.

What can I do to fix this?

ok, I flashed an old modem, and it worked:

How do I set Android’s Clock app to vibrate for timers?
When I set my Android to All Notifications Vibrate mode and set a timer with the Clock app, the only notification I get is an on-screen display of the time counting negative past zero. There is no vibration, so I can’t tell that the timer expired when the phone is in my pocket (especially when using headphones with my computer). I can’t figure out how to ask the Clock app to vibrate the device when a timer expires. How do I enable vibrations for this notification? If this is a bug, how do I report it most effectively?

Normal notifications such as toasts will generate a vibration so that I can tell there is a notification when the phone is in my pocket. The normal alarm function of the Clock app will vibrate the device just fine.

I’m using Clock-4.2.1 (2383161) on Android-5.1.1+OxygenOS-2.1.2 on a OnePlus2.

How to scroll horizontally in Terminal Emulator for Android

Use a disk image for Link2SD's 2nd partition
Well, this question is targeted for those few devices without support for an external SD card as well as merged storage, for example my Micromax Canvas Knight A350.

I thought this up today:

If we take a QEMU disk image file (.img), set it to static with a size for, say, 4GB and format it to ext2 and copy it over to the Android device's internal SD card, can we mount it as /mnt/sdcard2 or something similar as a loop device (it appears that loop device mounting is possible on stock Android 4.0.4 and up, at least for some Samsung devices)?

Secondly, will this work with Link2SD?

Context: My device, as mentioned above, has a 2GB /data partition which is fast running out. I thought this up as a last-ditch effort to extend its lifespan (because it has 25GB /sdcard0 partition`, and I don't use more than 12GB of it), and would like to get the theory of this validated or refuted before I go about trying this on my device.

NOTE:

Any alternative suggestions, such as FolderMount (kindly suggested by @Izzy in chat), are also welcome if these are accompanied with proper usage instructions for this specific case, that is, link folders from /data to internal SD.

Side Note: Not currently considering FolderMount as it's advertised for internal SD to external SD linking, not /data to internal SD linking.

问:
Amazon Kindle app and Personal Documents on Android emulator
How can I make the Kindle app in an emulator work just like on a physical device?

Background: I tend to buy ebooks directly from publishers and then send them to Amazon Cloud Drive to be converted into what Amazon calls "Personal Documents." Doing this allows me to synchronize annotations and bookmarks between my phone and tablet, just like with ebooks purchased from Amazon.

However, I'd like to get those annotations and bookmarks on my computer screen -- it's more convenient for me to type code while the ebook is up on the same screen, rather than having to keep shifting between computer and tablet. As others have noticed, the Kindle Cloud Reader and PC/Mac-based readers don't support Personal Documents fully (I believe the Cloud Reader doesn't support them at all; the native apps, last I knew, allowed you to sideload documents but don't synchronize them, but it's been a while since I tried); so I thought that since I have some Android virtual machines (using Genymotion) I might as well install the Android Kindle app there.

I was able to do that, and when I go to Amazon's Manage My Content and Devices page I can see the new device, but I can't seem to find a way to assign that device an Amazon email like my other, physical, devices. I also never see the Personal Documents in its list of books the way I do on my phone and tablet.

It used to be the case (around October 2014) that when I ran the Kindle app in the emulator, it displayed a progress spinner and "Checking for new items & syncing…" for an indefinite amount of time (I remember leaving it spinning for over an hour); now that doesn't happen, but still my Personal Documents didn't show up. In addition, if I reboot the virtual machine, the app asks me for my login information as if I had never run it on the device before.

So my main question is: how can I make the Kindle app in an emulator work just like on a physical device? Secondarily, I'm wondering whether the Kindle app somehow detect it's running in an emulator, and refuses to allow full access for that reason -- and if so, how; or is this some sort of subtle bug in the interaction between emulation and app?

I originally asked this on Ebooks beta StackExchange.

问:
Samsung Galaxy S3 speaker connection flickering, loose contact
Issue

The issue happens on my samsung Galaxy S3 model SGH-I747M.

The loud speaker doesn't work anymore unless I "hit" the back of my phone until it work again. But then I need to be VERY careful, because any touch to it can cause the speaker to stop working again. For instance, just putting the phone on a table can make it stop again.

Example :

I put some music to play without headphone. The music is playing in the app but there is no sound coming out. I hit my phone once and the sound start coming out then I put my phone on a desk and the sound stop coming out again even if the music is still playing in the app. I hit the phone on the desk a few times for the sound to come back. Since hitting the phone temporary fix the issue, I suspect the speaker connection is loose.

Issue solving

Playing music here was the easiest example, but alarm clock, phone ringning and every others apps that use the lound speaker does the same. Therefore, I suspect a physical problem. However, I don't know where the loose is.

Here they show how to change the speaker on the phone.
Changing the speaker would solve the issue only if the loose is within the speaker part. If it's before that, then it's won't solve anything I guess.

Question

Is the loose within the speaker part or within the rest of my phone?

If you can't tell for sure, then what are the probability for the issue to be within the speaker part?
Any other advice are welcome.

su fails: "wget: bad address 'static.zhiqupk.com'" and unable to unlock bootloader
A friend of mine bought a used Samsung Galaxy S6 or at least we thought so, but it looks that it might be a chinese phone. After wiping all data/cache, the phone still had a lot porn/advertisement apps, so we decided to burn original ROM. The only problem is that, we can't get to unlock bootloader.

When I try with adb oem unlock, it just hangs by ..., i.e.

```<code>$ sudo fastboot devices
mt6572v1_phone  fastboot
$ sudo fastboot oem lock
...
</code>```

So I tried adb shell and try to get root access, to see if can do anything from inside:

```<code>$ sudo adb shell
shell@rtech72_we_72_kk:/ $ su
wget: bad address 'static.zhiqupk.com'
Unable to chmod /data/.n.b: No such file or directory
        pkg: /data/.n.b

How to paste a text on non-pasteable (tap & hold pasting) text field?
My problem is that I have no way to paste a text in an app because the app doesn't allow tap & hold pasting. The keyboard I use (Google Keyboard) also does not have a clipboard button anywhere. The personal dictionary shortcut entry length is too short for what I'm trying to do and even if it were long enough, it doesn't work (doesn't even replace a simple "brb" with "be right back").

Can anyone suggest a way for me to keep using my Google Keyboard while being able to paste in a text field that doesn't allow for tap & hold pasting?

Is there a way to somehow add a clipboard button to my current (Google Keyboard) keyboard?

I ask these two questions as if there are simple answers to them because every single tool for a rooted phone boasts unlimited access to the user over your device, yet not a single tool that I've used has been able to provide me with a simple workaround to this simple issue of being able to paste in a text field that doesn't allow tap & hold paste.

I have a rooted Samsung Galaxy S4 on a CM11 ROM running Android 4.4.4 KitKat. I also badly want to keep my Google Keyboard, so if possible, I don't want to download another keyboard.


问:
How can an organization control when or when not an update for an app is installed in their Android smartphones?
Imagine an organization that have a legitimate fear to automatic updates. That organization thinks that an automatic update may break a business use case. For example, when the VPN client is update the users are no longer able to connect to the VPN. By automatic I mean installing the app without the organization participation and without the organization being able to test the update in advance.

How can an organization control when and when not an app update in installed in an Android smartphone or device?

As long as I know, if you install an app using the Play Store, the organization cannot control the updates if the user enables "automatic updates".

If the organization install the app using the APK, the application is not updated automatically but in the future the organization has to update manually the app and also if you install the app using the APK the app is not installed as "device manager" and the app can be uninstalled by the user (think in a security app like a MDM agent).

The organization uses an MDM (Airwatch) but it does not allow to control the update of Play Store installed apps.

Android Wear sync 'freezes' phone interface
I have an Asus ZenWatch 2 paired with my Nexus 6P. (In the past the same watch was paired with a Moto X (2014) with the same symptom.)

When the watch connects to the phone after having been disconnected (such as by going out of range), it often causes the UI on the phone to freeze for around 15-20 seconds. I.e., the phone doesn't react to touches at all, or at least has a lag of several seconds before reacting. After 20 seconds or so, the phone behaves normally again.

The symptom is similar to how my old Nexus 7 (2012) would behave after the infamous 'slow flash' performance issue reared its ugly head. (Not saying this problem is in any way related; it's just a similar behavior.)

I've tried to see what might be monopolizing the CPU using System Monitor as well as top via adb shell, but I haven't managed to gather much good information.

Has anybody else experienced this? Any tips on isolating the problem?

Root SGS3 with stock recovery
I'm going to stay on topic and make the long story short. My phone (International Galaxy S3) has its USB port broken and can't replace it because I messed it up when I was on it. Since then I use an external battery charger.
Now I need to root my phone and flash a custom recovery and since the easy way (Odin) is with USB I have to try something else.
I have already tried rooting with different apps (Framaroot, towelroot, KingRoot) with no success.

I have been reading on internet to figure out a way to root it or flash a custom recovery but everything comes into a dead end.
One of the possible solution I have found is rooting phone via Android Stock Recovery (the 3e one), but this would require a signed update.zip. Is this possible or it could hard-brick my phone? If it is possible, how do I make it?

The zip file needs to be signed and have a certain folder organization (META-INF and system). I could sign it with an app I discover in xda forums called Sign'em (can this work out?). But I have no idea about folder organization of the update.zip file. I downloaded a file called "Update-SuperSU" from chainfire's website which comes with META-INF folder but instead of system there are 3 extra folders: common, arm and x86. Is it the same?

If there is another way to root the phone or flash a custom recovery to do so, please tell me. Any help will be appreciated

options for solving one way audio issue during voip call?
Buying a new phone may be one solution, but that would be a shame. :-)

Huawei G500 Pro (U8836D)  ICS 4.0.4

From the outset, voip/sip calls using any application would have the problem of what would seem to be one way audio; the person at the other end (whether initiating or receiving a call) can not hear anything being spoken (from the G500) but at the G500 the other party is clear as a bell.

I have read many articles across the internet, but there does not seem to be a definitive answer/solution and certainly not one that has worked for me so far.

I have tried many apps making changes to the various settings where facilitated. I have also tried the MTK engineer settings to adjust volumes etc in the hope it may cajole it to work.

In addition, a different ROM has been flashed (the one from BGCNGM [Bruno] on the xda developer site) for amongst other things to see if that fixed anything. It did not; same situation as with the stock.

If any one knows what the issue actually is (module missing or faulty, kernel issue etc) and has a solution(s) to try, that would be great.  I can live without it, but it would be nice to see if it could be resolved ?

Nexus 6 has Still not Received Android Marshmallow November Update
Whenever Google released Android Marshmallow, I sideloaded it on to my Nexus 6 using adb sideload. After the release of Android Marshmallow, it took Google a few days before they released the OTA update packs for the Nexus 6, but as soon as they did, I jumped on the opportunity to upgrade to build MRA58K.

Since then, Google has released the November update for Marshmallow (there are two builds listed here for the November update, MRA58N and MRA58R) but I have still not received the OTA for it by waiting.

Although I was patient, I'm somewhat concerned now that we are gearing up for the release of the December patches while I still haven't received the November patches.

Should I be concerned about this, or is this normal? I found a nice list here of all the new builds added with the November update, and I'm unsure of whether I should sideload them or just wait in hopes of receiving the update in the standard way.

I also sideloaded the initial OTA for Marshmallow on my dad's Nexus 6, and he has also not received the update.

After a while I was stupid enough to install an unstable version. Which caused my nexus to basically break ( when I say break I mean I couldnt get past the recovery mode screen).

Currently I am stuck in recovery mode. I turned my nexus on today after years.
And I see this ( I apologise for the bad quality of the image )

I have no idea where to go from here. How Do I fix this? Whats the next step.
I honestly have no clue at all.

Any help will be greatly appreciated.

Screen shot in power menu
On a previous phone, the HTC One X,  I had the print screen option show up in the power menu. It was along side shut down,  restart,  etc..

I now have the Vodafone Smart 6 Ultra but I can't find any settings relating to the feature I want.

Is it possible to add the screenshot menu option without rooting my device?

App folders on homescreen being removed automatically when a new app is installed
I have HTC Desire 820 running on Android 5.0.1 Lollipop. I have folders with favorite apps on the home screen. But whenever a new app is installed, all those folders disappeared, and the home screen was being set to default.

I cannot rectify this issue and even cannot find out why this is happening. What is the possible cause and how to fix it?

Google Calendar Widget Week View
How can I set the Google Calendar Widget to show the week view instead of the month view? I've browsed through all the calendar settings and just can't find any way to modify the widget's view. I can also add a "Mini-today" widget but that's not what I want. :)

My phone is Samsung Galaxy S5 Mini and the OS is Lollipop.

Kind Regards,

Upgrading an older tablet (from 4.4)
Is this a question which has a definitive (and generic) answer? I don't know, which is why I ask.

If I buy an older tablet on Ebay, which is running Android 4.4, can I upgrade it to 5 or even 6?

Is there a single answer, or is it model by model specific?

If I decide to try it anyway, I would like to hope that I can't brick it so badly that I couldn't reinstall 4.4 - can anyone confirm or deny that?

And what sort of things do I need to look out for? I imagine that older processors are likely to run newer operating systems more slowly, so performance could be an issue. But, is there anything else that I need to be aware of?

I do hope that this question doesn't get closed as being too vague, because I believe that there is/are a precise answer(s) could be very helpful to a lot of people.

How to find logs of unhandled exceptions in Android?
In Windows, when an application crashes because of an unhandled exception, there is a place called Event Viewer that gives a good amount of informative data about the process being crashed down.

Using that information, one can easily troubleshoot the application.

In Android, we have developed an application that on the phone of a customer keeps crashing repeatedly and we don't have a chance to log anything.

Do we have something similar here in Android? Or in general, how should we know about unhandled exceptions in Android?

Please note that because the app is installed on customer's phone, it's a user question. We want to know a way to be able to find a log somewhere somehow by the help of our customer, and act accordingly.

How can I sync my Google Work Calendar with my Android Phone
I don't want to add my Gmail(Work) on my phone because it requires all those device admin profiles and the Admin controlling that will control my phone.

I've managed to sync work emails via IMAP in the Gmail App, now I have issues with the calendar. Is there a way to sync the gmail work calender?

eg myname@mycompany.com (Google Apps for Work) Calender with my Android Device.

I know I can share the calendar with my personal account and then access it, but is there a way I can add that calender to my phone?

I see there is an Exchange Account on Android 5.1 would that do the job?


问:
Why do the *.asec files dissapear from /sdcard/.android_secure when phone boots?
I have been puzzled by this for sometime, I have found out that these *.asec files migrate to /mnt/secure/asec on my phone after it boots but it still seems they occupy space within the sdcard and if you delete any of the .asec files in /mnt/secure/asec a corresponding space is also released in the sdcard though they are nowhere to be found within the sdcard.

After switching off the phone everything goes back to its place and the files are visible in the .android_secure folder or when sdcard is removed, I would really like to understand this behaviour, what happens in phone to cause this??

Find the file referred to by a home screen icon
I have an icon in my home screen that I haven't installed and looks like malware (Logo of O2, which is not my network, with the name "Priority". I opened it once and it showed commercials).

Last week there was another strange app installed too which I just removed from the home screen. However, I would like to know what is the file behind this "O2 Priority" icon that appeared in my home screen so I can delete it. Is there any way to do that? Any help appreciated.

Unable to turn on device - see whit pixeled screen
I tried to flashify my ZTE z5 with a not suitable recovery for this phone (TWRP 2.8.6) and now I am unable to turn it on.
I can only see a white pixeled screen and not able to get into recovery mode (using vol down + power).

ADB does not recognize the phone (when write "adb devices"in cmd), but windows does recognize it as "Android", but I do not have access to the local drives (I do not see the NX503A in the "Devices and drives" section)

Is there a way to rescue it?

Thank you!!

I just bought Droid Turbo (XT1225) from ebay, everything works fine except the radio, when the phone receive no signal for example in a lift, radio will turn off by itself and can't turn back on.

问:
Unusual GApps running in background
I was always curious to look into the current running apps in my Android device(running KitKat 4.4.4) and check which app takes up more ram.

As you can see in the screenshot, play music is running even when I'm not listen to songs and Google maps is running for hours when location is turned off (turned off WiFi search for location in advance setting too).

Can anyone explain why this is happening?

Thank you.

问:
Stock Android app manager requires app to be Force Stopped even though it is not running
When I go into the stock Android KitKat stock app manager, many apps indicate that they require being Force Stopped before they can be moved to external storage, whereas other apps do not.

This would make sense if the apps requiring Force Stop were running, or were running a service.  But they are not.

An example is the game Little Crane.  The game is not running, nor has it been run since the phone rebooted.  Using OS Monitor, I see no processes related to that app.  Yet, the stock Android app manager indicates that the app must be Force Stopped before it can be moved to external storage.  This implies that Android thinks that a thread related to the game is running.

Can anyone explain this phenomenon?


问:
When does Android plans to bring icon notification?
Moving from an iPhone to Android, I am surprised that Android does not have built in option to display app notifications (ex: number of unread email messages on the app icon).

I know there are many other apps and launcher which allow you to do this, but why isn't this built in yet?

Is this something that Android is planning to bring in future releases?

问:
WiFi network is not saved when phone is rebooted
I recently rooted my Samsung Galaxy S6 Edge+ and have found that every time I reboot my phone, I have to re enter my home WiFi network password again. I checked my wpa_supplicant.conf file in /data/misc/wifi and found that when I connect to my WiFi network it is saved to the file but when I reboot, it disappears. The strange part is that other WiFi networks I have previously connected to remain in the file. This is what the the file has for my WiFi network after I connect:

```<code>network={
    ssid="My Wifi 5GHz"
    psk=7281996584ae07843694243231a22d0d
    key_mgmt=WPA-PSK
    priority=15
    frequency=5180
    autojoin=1
    usable_internet=0
    skip_internet_check=0
    verified_password=1
}
</code>```

What's the issue and how do I fix it? Thanks.
