问:
Notifications panel disappeared and other issues
Unlocked unrooted Samsung Galaxy S7 running Android 6.0.1. Suddenly started having the following issues after being restarted:

Notifications panel disappeared both from home screen, and notification bar when expended.

Notifications bar doesn't show any icons for apps with notifications - just the carrier's name. (However, the phone still vibrates and plays notification sounds when I receive a message for example - the LED also turns on)

Recents button doesn't do anything (hardware responds, but does nothing).

Holding down the power button only shows "Power off" and "Restart' -
no more "Airplane Mode" option.

After expanding the notifications
bar, tapping the cogwheel and down arrow in the top right corner does
nothing.

Things I've tried with no luck:

Restart

Power off, then start

Restart by holding down the power and volume down buttons.

Reset settings to defaults

Current settings:

Airplane mode is disabled

Power saving mode is disabled

Ultra power saving mode is disabled

Notifications are enabled

Notifications on lock screen set to "Show content"

I tried looking into all the settings, but I'm stumped. Any idea what's going on?

Extract a gpg file in a nexus 7?
I want to extract a gpg file (passphrase only, no key), with a Nexus 7.  It's just a gpg with a txt file inside.

How do I get it to the nexus 7 and then even if I can extract it, how do I get to it with a text editor?  I can scp it from my lan server to get it here (the n7).

I have the juicessh installed in the n7, I figured that's a good place to start, but how would I even do it from within juicessh- can I login from localhost? I tried loggin in to 127.0.0.1 but the ssh connection failed (perhaps not a surprise).

Seems like a simple thing but it's apparently not.

thanks

What are the contents of ipconfig.txt file on Samsung i9070?
I've got the aforementioned phone, Samsung i9070. However, for some reason (after mucking around with various ROM's) wifi stopped working at all. Theoretically I can turn it on and off, but no networks can be found.

When flicking the wifi switch on, following log gets written to adb logcat:

```<code>E/WifiConfigStore( 2341): Error parsing configuration: java.io.FileNotFoundException: /data/misc/wifi/ipconfig.txt: open failed: ENOENT (No such file or directory)
E/WifiConfigStore( 2341): readNetworkHistory: No config file, revert to defaultjava.io.FileNotFoundException: /data/misc/wifi/networkHistory.txt: open failed: ENOENT (No such file or directory)
E/WifiConfigStore( 2341): ctrl_interface=/data/misc/wifi/sockets

D/wifi    ( 2341): getting scan capabilities on interface[1] = 0x469e95f8
D/wifi    ( 2341): failed to get capabilities : -95
</code>```

I'm guessing the missing /data/misc/wifi/ipconfig.txt file is the problem here (Or something's wrong with the radio, but I'd rather not try to reflash OEM's 4.1 yet, as it's a hassle installing recovery and cyanogen again), and other roms I tried do not have that file, it seems.

So, anybody that has that phone could please copy me the contents of that file?


问:
Smart Lock, and multi-factor authentication?
I am using Marshmallow, and I use the built-in encryption mechanism.  Typing my password every time the screen locks is a pain.  I would like to leverage Smart Lock to have the following ideal situation:

If my phone is far away from me, I'd like the phone to immediately lock; thus requiring a password to decrypt. (This way, if my phone is lost, or even stolen, then my data will be safe.)

If my phone is nearby me, I'd like it to simply "soft lock" my screen; i.e., require either a PIN or facial recognition to unlock the screen, but not my full password. (This way, if I leave my my phone at my desk at work, for example, someone sneaky can't snatch it and snoop at my text messages or who knows what.)

Before I go on a wild goose chase, can someone please tell me if this setup is possible with Android?

Weird battery behavior with new battery - Moto x 2nd gen
I have a Moto X 2nd gen (2014) that I got about 2 years ago. The battery has been failing recently and was dying at around 20 to 30%. I ordered a new battery on ebay that claimed to be genuine (It's label looked identical to the battery that came out of the phone). After replacing the battery, it has been dying around 60 to 70%. I have followed the instructions outlined here to no avail. After dying around 70%, I leave the phone off and charge it. It starts at 0% and goes to around 30% where it lingers awhile (1 to 2 hours) before jumping to 100%. Any idea what is causing the issue? I don't believe it to be an old battery dressed as new because these 2nd gen Moto X batteries come out bent/curved and the new one was flat. Any further steps I can take before ordering a different one? Could a factory reset help?

Thank you.

Edit: Here's a screenshot after it's hung around 30% (at 34%) for awhile on the app Ampere. It has cell voltage and charging current. It seems like the voltage is to high for 34% and the charging current is too slow... link

Flashing a soft bricked Blu Life One XL
Recently I tried to root my phone using KingoRoot. The result was a BLU Life One XL that wouldn't load past the BLU logo.

The first thing I tried, was going into Recovery Mode and clearing cache and reloading, then clearing user data and reloading. Neither worked. After some research, it looks like I'll need to flash stock or some other compatible ROM to my phone.

As such, I downloaded a ROM from the XDA forums, stuck it on my miniSD card, and tried to install it through the recovery mode menu. However, the result was an error dealing with signature verification failed and installation aborted. To get past this, apparently I need TWRP, CWM, or some other custom recovery where I can turn of signature verification. I've tried adding these from the SD card both as zip and Bootable SD card, but neither worked. I can't even get to the bootloader since if I choose the reboot to bootloader option from the Android system recovery, it just gets stuck at the BLU loading screen.

So, how can I flash a ROM to my phone without being able to load past recovery screen? I think if I can only get custom recovery on my phone it should work, but I can't figure out how to do that.

Samsung Galaxy Note 10.1 Bootloop?
I purchased a Samsung Galaxy Note 10.1 in 2013, GT-N8010, Android 4.4 and recently, I had a problem- when it loaded, it said Samsung Galaxy Note 10.1 and didn't load. I tried to factory reset it holding volumedown and power button, and it asked to go into ODIN mode- said a custom OS can damage the device etc. Then, on ODIN mode, it said:

ODIN MODE

PRODUCT NAME: GT-N8010

CUSTOM BINARY DOWNLOAD: No

CURRENT BINARY: SAMSUNG OFFICIAL

SYSTEM STATUS: Official

It froze and sometimes stopped when it was connected to my laptop. I then held both volume buttons and it went onto charging. I don't know what to do. I don't know why it said custom- I didn't tried to get a new android version or to root it.

I've tried out the following:

wipe data/factory reset

It does not work

wipe cache, and then wipe data

It also won't work

try using adb [command] while turning on (bootloop)

adb devices returns null

apply update from ADB

adb devices still returns null

apply update from external storage using the ROM uploaded here

Installation aborted printed out after Verifying update package...

Any tips, Android StackExchange?

Setting up ringtone on Nexus 5X with Android 7.1.1
I am just writing about what worked on my new Nexus 5X which has Android 7.1.1. As I have read many answers about how to set up a ringtone and none of them worked.

I installed a file manager app and then I transmitted the custom ringtone MP3 from the old phone to the Nexus 5X using Bluetooth which put it in the Downloads folder that I was able to browse in the file explorer app. So far so good.

I then tried copying the file to the Ringtones folder in the root directory (/storage/emulated/0) but couldn't select it in Ringtone settings so I had to try reading some messages to work out where I could try to put the file to get Android to detect it.

After looking at a few places I ended up putting it in the Android/media/com.google.android.talk/Ringtones folder. After that the Ringtone was able to be selected in sound settings.

Recover Hangouts data using Android File Transfer

Why file permissions work in unexpected manner? And what makes it possible
My app doesn't have storage permissions, yet I can read/write files in /data/user/0/com.myapp/files .

When on emulator connected as root I can push a file to this directory, but then the app cannot read it.

After I chown it to my app's uid:gid it still cannot read/write to it.

If I do run-as com.myapp touch newfile and then as root cat pushedfile >> newfile, then my app can read newfile.

What kind of dark magic is that? Why regular unix file permissions don't seem to work, and what mechanism prevents the app to read pushedfile even after it was chowned?

How to partition SD card using LG G Vista as card reader(without root)

How can I prevent a downloaded Google Play Book from being purged?
I have purchased a digital book on Google Play. To read a book, the Google Play Books application downloads a copy to my Android device. This all works as expected.

The problem is that I read this book only intermittently, and when I return to the Google Play Books application, sometimes the application needs to redownload the book. This is a problem in situations where data is unavailable (on transit, for example). I guess some kind of periodic cache purging is taking place.

Are there settings that will prevent the book from being removed from the Android device? I have plenty (~5GB) of storage space available, and I would prefer that the book simply be saved until I manually remove it.

Keypad Freezing Up - think it's a Touch Wiz issue? (can I get around this with a Launcher?)
I would be grateful for some feedback/suggestions.

In short, I have an ageing (badly) Android 4.4.4 - Samsung Galaxy Ace 4, AVG and some Avast Apps on the Virus Checker side, and Touch Wiz.

Something that has happened since Day 1 is occasionally when using Social Media Messaing apps on data (e.g. Whatsapp and Signal in data mode, never happens in SMS) occassionally the keypad will just totally lock up (e.g. be visible, but won't take any input or I will get a delayed input, and it won't pick up the right letter - e.g. tapped 3 times for a "C" and I get an "A" - 45 seconds later).

When I re-start the phone, everything is back to normal (until the next time it happens - which is never far away - e.g. no more than 15 messages).

I have done a little reading around and someone suggested clearing the Touch Wiz Cache which did seem to help and delayed the re-occurance of the problem (I don't know why?).

From doing a little more reading it seemed that I may be able to get around this by using a Launcher (e.g. Nova) to bypass Touch Wiz (which doesn't seem to have a lot of fans).

Would this be the case or have I misdiagnosed the problem?

I would be grateful for any advice.

ADB is causing kernel panics in OS X
The following question is irrelevant. While MDM is problematic in many other ways, it is not responsible for the kernel panics.

I also learned that Motorola mistakenly cites that its drivers must be installed to use ADB, this is not the case for OS X, which is the OS in question.

I have a Motorola X 2013 Developers edition. The ADB drivers for the phone are part of another software provided by Motorola called the Motorola Device Manager, and it caused 3 kernel panics on my laptop today, and more than I can count over the last week before I isolated the responsible package. I linked 2 kernel panic logs below, but this is the last line in the console before the crash every time.

12/22/16 8:13:16.000 PM kernel[0]: stalling for detach from Motorola ADB Interface

Then all hell breaks loose. It appears that the driver crashes when the computer enters sleep mode while the phone is plugged in. And no, it doesn't matter if the ADB is activated or not.

I've contacted Motorola about it and they said that they have never heard of this happening before, but they'd look into it. I have no expectations of them fixing it any time soon.

How to write to / delete from external SD Card on Android 6.0 Marshmellow Huawei P9
I'm coming from a rooted Samsung S4 to a non-rooted Huawei P9. With the rooted S4 I could do anything at all, the stock P9 is extremely restricted. I want to stay with stock because it's a phone that's been loaned to me and I don't want to risk breaking it, and I'd like the Android 7.x over the air update in a few months without having to unroot.

I would prefer not to mount the external SD as internal memory, as it's slower. I've tried creating files, deleting files, and changing permissions, I can't do anything.

Basically I would like to be able to do two things:

Add and delete files to the external SD card using a file manager,
such as Root Browser

Have Bittorrent Sync (or other apps) write to the external SD card

I know Android security was ramped up around Android 5, but this much restriction is crazy. Is there a way around to do this working within the stock OS? I may just have to give up on external SD, it seems pointless to have it right now.

The phone cannot be restarted using the normal on and off button. I actually have to remove the battery and put it back for the phone to restart again. Anyone with a clue?</p>

high volume warning window cause system halt
I'm using Nexus 6 for a long time, but after some safety update, a problem came up. Before, when you raise the volume above a certain level, the system would warn you that it is bad for your hearing abilities. But now, the warning is gone, and instead, it would make the system app stop, like an unhandled exception is thrown, and the app will reboot. I guess the app is called System Interface or something similar.

Other info:

```<code>Phone: Nexus 6, not rooted
System version: problem occured at Android 6 (Marshmallow)
                but in Android 7 (Nougat) it is still there
Problem occur time: When earphone was plugged in, and volume is turned up.
</code>```


问:
Gboard ruined my typing experience, how can I change it back?
My phone just got the new Gboard, and to be honest, I haven't noticed much of an improvement. Maybe I don't use its many celebrated features as much as I should.

However, I have one big problem with it the way it is. I use my phone to mainly type two languages: Norwegian and English. Before the update, I would switch between them by the touch of a button (the globe icon next to the space bar), and for those rare occations I needed something else, I could momentarily enable them in the settings. I used the English layout for writing English, and the Norwegian language to write Norwegian. This way, the moment I begin to write, the swipe function knows which dictionary to test for what I'm trying to type, and everything works nicely.

However, with the new Gboard, it can do both languages at once. Apparently, the internet is happy that you don't have to manually switch, but I am more annoyed at the fact that when I begin swiping, the keyboard doesn't know which dictionary to use, so I can swipe all I want without any words coming out. I have to manually type a few words first before it gets the idea, and from there it works nicely. It also makes it much more difficult to mix both languages into a single small text.

How can I get back to manually switching between languages? Is there a setting I've missed, or do I have to roll back to an earlier version?

I'm on an LG Nexus 4, running Android 5.1.1, and Gboard version 6.0.69

Using Tasker to detect when a waypoint is reached in Google Maps
I have an issue with my Google Maps app where it doesn’t always tell me that I have reached a waypoint. I have contacted support and they could not find any solution (found here).

So I am hoping that Tasker can help me. I have found that when I reach a waypoint that the Google Maps notification bar icon disappears so I am hoping that Tasker will be able to detect it and run a task.

While I have set up simple tasks before this is a bit out of my league so I am hoping that I could have some guidance setting this up. Or, if necessary, an alternate solution (Ideally fixing the original problem).

Convert a game asset to image
I have a game on my phone that I really like. I was astonished by the portraits of the characters. I found the portrait within the game files but it has no extension, but I know myself it's counted as an image file within the game. Is there any way to convert the game asset into any image format?

What is this mysterious blue dot?

Click image for larger version

It pops up randomly when I'm using my phone. However, it ALWAYS pops up when I open Google maps. It then seems to emulate a repeated clicking motion, which freezes my phone to the point I have to do a hard restart.

I am using am HTC One m8

(I'm not sure about this but I'm pretty sure I saw a literal mouse cursor come out of the blue dot one day)

Secure low budget smartphone
My device:

Motorola Moto E. (android 4.4.4), rooted with Xprivacy to control permissions.

The Problem:

No security updates since 2009.

Can't find a way to use Google Play Market without giving it too much permissions.

Leading to...

The Situation:

Since I cannot find a good alternative market, I'm stuck downloading apps from my computer and copying over to phone (tiring, and c'mon it's 2016).

I don't browse the internet, becouse of the non-patched vulnerabilities.

What I want to do:

I want to flash a secure ROM with constant security updates like Nexus devices are getting,

Be able to use Google Play Market without it spying on me;

I don't want another OS, since I'm dependent on few apps like Sleep Cycle, my task manager and Dropbox.

What I tried:

I've been browsing forum.xda-developers for a couple of days, where I did stumble upon custom AOSP ROMs for moto E, but usually it also says things like:

This is started from kernel and device tree by CyanogenMod.

 (Is it the same as AOSP then? Will I get the same updates?)

Regarding CyanogenMod; It's not an option.

As for Google Play Market, it gives an all-or-nothing ultimatum. Either I give it all permissions, or It doesn't work properly.

I find it absolutely incredible that as long as only proxies for money (your sensitive data) is at stake, most people are ok with it.

Also while I deem myself quite savvy, I found myself totally disarmed with the lack of options, this question is my last resort.

If this is not the apropriate forum, please, let me know I will move the question.

All constructive critique welcomed!

Thanks in advance.

Video errors across apps
I have an annoying problem. My Huawei honor 4c began some time ago to refuse to play videos on many different apps. I first noticed the problem on YouTube (I get the common "tap to try again" error, but the app immediately freezes). Then I realized I can't play videos on Google Photos or Facebook either. Peculiarly, I noticed I can't even record videos with the camera app.
All errors (that is, in all affected apps) are resolved with a reboot, but at some point (apparently random?) they appear again.
I haven't installed any new app or anything of the sort.
Any ideas?
The Android version is 4.2.2</p>

Minimum volume is to loud
I have bought a new Alcatel Pop 4S which I'm quite happy with, but one thing is really annoying. No matter if I'm using build in speaker or headphones, outgoing sounds are really loud for me. I have found that "minimum" loudness is 6% so I wonder if there is some shell command to set up loudness to e.g. 2%. I know that there is app called "Fine Volume Control V2", but I don't want to pay just for this one function if there is some another solution.

Thanks for your help

问:
Internal storage used space readings differ
Context

I have a Motorola XT1068 phone with Android 6.0. It has 8GB of internal storage, of which 2.5GB are for the OS and 5.5GB for data. At one point, when connecting it to my computer, I noticed that the used/free space for the internal memory has different values depending on where you're looking.

The readings

Android settings > Storage & USB: 4.79/5.51GB used

Android settings > Storage & USB > Internal storage: ~3.3GB used when you add all up

file explorer front page: 4.84/5.51GB used

file explorer > browse to / > select all > Properties: 7.92GB used (this must also include the OS)

PC > My Computer reading: 179MB/5.50GB free, so ~5.32GB used.

If the cache keeps growing, it will eventually reach a point where the PC reading says no space is left, yet the phone says there still is.

I am honestly at a loss on what reading is the correct one, but also on why they differ so much, especially why the PC shows much less free space than the phone makes it seem.

I also have a memory card in the phone, however the free/used space data remains constant across Settings/file explorer/PC.

Can I use ext4 on my SD card on a non-rooted android 5.1.1 (lollipop)?
I'd like to use ext4 on my SD card, or anything besides fat32 really. Something which supports files > 4GB in size.

Unfortunately, unlike it apparently was back in the day, now ext4 and even exfat-formatted SD cards are met with a message like "filesystem missing or not supported, click 'okay' to format", which when clicked, causes android to happily reinstate a fat32 filesystem.

Is there any way around this on an unrooted system?

Or am I stuck?

Phone is booting with a specific battery on Samsung Galaxy S3 with CyanogenMod11
Yesterday my Samsung Galaxy S3 fell and shut down.

I have tried many solutions to turn it on but the only thing I could do was to enter download mode.

Today I tried to replace its battery with my old one's battery and the phone is working good!

So what with the other battery could be problematic?

Both batteries must be good because I can turn on the cell with them (even though with one of them I can't boot past download mode) and the rest of the hardware must also be fine because phone works fine.

TowelRoot v3 User Interface Anomaly
I downloaded the latest TowelRoot (v3) from the official website and I noticed a UI anomaly and wanted to know if anyone else has experienced this. Most screenshots of the "make it ra1n" screen (from other peoples' phones in tutorials) are complete, however on my tablet the last part of the "n" was cut off making it appear to be "make it ra1r". (Screenshot 1)

After switching to portrait I was a little more assured when I could see it was just cut off. (Screenshot 2)

I want to know if this was a known problem or a mistake by someone trying to reissue a counterfeit. I've looked at the whois domain registration and it appears to be under the control of the same owner since 2014. (Screenshot 3 and 4)

Accessing an Android watch via USB COM port through command line to install applications on it
I have a Goclever watch that runs a dummy Android. It has a USB and Bluetooth, but no Wi-Fi. It has no device info in its menu and the .apk files are not installable from its file manager (only mp3 and jpeg files can be opened). When plugging it to my Windows desktop it's recognized as a MediaTek USB COM port device, but adb devices returns an empty list.

Is there a way to somehow hack into it via command line, installing applications from .apk files onto it? I need at least Sleep as Android, because though the watch has its internal accelerometer it's not acting in behalf of the phone's accelerometer (so whenever I launch Sleep as Android on my phone the sensor signals are not picked up by it).

BTNotification is up and running perfectly, the selected applications keep pushing the notifications to the watch and even phone calls can be made through it.

The BT device list in my phone identifies the watch as 6261 so I guess it has an MTK 6261 processor in it though I'm not completely sure.

APK install error "App Not Installed" Unity App
Im not particularly sure where to go for this question but this seems to be an error more with Android than my development software.
I have created a Unity Application that does not seem to take much space, Only around 90MB currently.
The previous versions were able to install it no problem from an APK file but now that I have the fourth level created, It says "App Not Installed" when I try to install it.
I removed the fourth level and tried installing it thinking it could be just an issue with Unity. But then when I tried to install it with just the First through Third Level, it did not work until I dropped the game down to 29.92MB which is only the first and second level.
so I figured it was an Issue with my Android System and not the game itself.
I see alot of people with the same question but I havent seen one yet with this type of error.
Any help with this issue would be greatly appreciated
feel free to ask me any details because Im still a bit new to this stack exchange thing

How can I make GMail display whole email thread?
The GMail app groups together email chains in reverse chronological order.

The idea is good, but I am now missing emails. It says 10 emails in the header in the inbox, but it only shows the last 2 and I know there should be more.

Google's own mail does not allow switching off conversation view, I think? Their web mail has the same problem.

问:
What does "Enable OEM Unlock" do, and how can I do it through a root shell?
Looking at this Samsung Galaxy A8 question, I was looking to do something on my Nexus 6p.  I would like to enable OEM unlocking, the developer setting.  Due to the problems my device is experiencing, I would like to do this through the android root shell.  What does "Enable OEM Unlock" do on the device, and how can I replicate that change using a terminal.  It's on pure nexus, if that helps.

For anyone who wants to know, this is the current state of my device, if there are other possibility:

My recovery partition appears to be corrupted enough to be unusable, my main os (pure nexus) appears to be fine, but considers my phone to be corrupt and tries to reboot into recovery after I give it a password to decrypt my device (which I never set, and any password it calls correct and corrupted data).  So, I have root access in adb, including shell access which as far as it looks from me is the full device.  Using adb, I have tried opening the settings menu, which tells me that the current user(none) cannot change the "enable OEM unlocking" status.  But, that setting must be doing something simple to allow the device to be unlocked, right?

So, this is probably my fault, and will NEVER be done again, but I got to this state from trying to lock the boot loader after I got most of pure nexus working, as I just wanted to wipe it from any excess, figured I could kill 2 birds with one stone.  Since then, I have tried every factory reset I could find out there, all either need a working recovery(for the side loading a google signed recovery) or need an unlocked bootloader.

Samsung Galaxy S7 Edge keeps freezing/restarting randomly
This issue started yesterday. I was playing Hearthstone but all of a sudden, my phone froze for about 30 seconds and then restarted. I went on my phone again but this time it was frozen and I had to leave it overnight to discharge. Today I found a way to restart the phone if it is frozen by pressing Power + Volume Down but I still get freezes. Sometimes the phone just randomly restarts. Occasionally I get this thing with a flashing red light and I am unable to turn the phone on. I fix this by plugging in my phone to the charger but I don't want to keep doing that. I factory reset my phone but problem still persists.

P.S: My phone is hotter than usual.

问:
Xbox ONE Bluetooth controller won't pair anymore
I bought an Xbox One Bluetooth controller and it worked just fine. I tried to pair it again, but the controller turned off mid process and now a "Cant pair with Xbox Wireless Controller because of an incorrect PIN or passcode" dialog box appears.

I tried formatting the phone, removing the device, soft reset both phone and controller, booting on safe mode and booting to recovery and wiping cache data – but nothing of that worked; connecting it via OTG doesn't work either, it receives power but is not detected by the phone.

I'm using a Moto G 4 running Android 6.0.1. Any ideas on how to get that working again?

Why init domain failed to execute shell_exec type though there is "domain_auto_trans(init, shell_exec, init_shell)" in the sepolicy?
I'm trying an root exploit on android 5.1.1 and I have gotten root permission with u:r:init:s0 context now. But when I tried to execute system("sh"), it was denied:

```<code>type=1400 audit(62.480:16): avc: denied { execute_no_trans } for pid=1166 comm="sh" path="/system/bin/sh" dev="vda" ino=349 scontext=u:r:init_shell:s0 tcontext=u:object_r:shell_exec:s0 tclass=file permissive=0

I looked into sepolicy file and I got this:

```<code>domain_auto_trans(init, shell_exec, init_shell)

Is it not enough for this execution? If so, what should be added in sepolicy?

How to chose the right version of SuperSU.zip for flashing?
I flashed TWRP on my ZE551ML (Z00A-WW-2.20.40.198) and wanted to root a clean stock rom. I have successfully done so before on the same device by installing BETA-SuperSU-v2.67-20160121175247.zip downloaded from the official Chainfire site. I thought it would be better to have the newest version, so this time I tried to install SR1-SuperSU-v2.79-SR1-20161221223537.zip from the same source. However, after installing that file, the phone stayed in a bootloop for around 10 minutes.

Is it normal for it to take that long, or does that mean that the second file is incompatible with my phone?

Did I chose the wrong file, and should I have installed BETA-SuperSU-v2.67-20160121175247.zip instead?

Which zip should I install?

I have uninstalled again, and my phone boots. What I am asking about here is which file to install.

Phone is trying to store incoming SMS messages on SIM card
My Nexus 5X has stopped being able to receive SMS messages. Every time I'm supposed to get a text, I instead see a notification: "SIM card storage is full -- No more space for SMS messages on SIM card. You may need to delete some messages."

I have never configured the phone to use SIM card storage (don't even know of such an option). When I click the notification, I see an empty list titled "SIM card messages" in Messenger.

I'm currently traveling abroad and roaming (Sprint subscriber on Chunghwa). Sprint was having an outage with international roaming for several hours; it just came back on and the problem started soon thereafter.

Backup Pebble App
I have owned and loved a pebble time smartwatch for about a year now. Because of Pebble's recent demise, I'm considering buying an extra pebble time in order to replace my current one when it eventually kicks the bucket. However, there is no guarantee that the Android app and pebble app store will still be available when my current watch kicks the bucket, or even when I need to replace or factory reset my phone.

Is there a way to make an offline backup of the watch's current state and the app, such that it would be possible to install the Pebble app on a new Android phone from the current copy, which includes all the apps I've installed for the watch?

My goal is to preserve the app and watch configuration indefinitely for as long as possible, which I think I can do if I can successfully preserve my current copy of the app. Is that possible? Will there be any problems if I update to a newer version of Android? (My current phone is running Android Marshmallow 6.0.1). And overall, will this achieve my goal of using a pebble watch for several more years?

Keep asking for apps on every action on Marshmallow
In Lollipop, I was being asked for the app to be used for every action. For example, when I open a link, I was asked for the browser. When I have to select an image, I was asked about the app that would browse for images. This behavior is very convenient for me.

Now after upgrading to marshmallow, I get asked only once, and then that becomes the default. Meaning that if I do a mistake, I'm done. Now for the browser, I see the option for that in settings -> Default Apps. But for selecting images, I don't see that option. I selected ES file explorer for that and I'm stuck with that.

How can I change the default image selector app, or even better, how can I be always asked every time I do an action that requires anything that has multiple apps that can do it, just like it was on lollipop?

EDIT:
There's no option to use app only once. Check out the screenshot.


问:
Can't flash using fastboot
I lost access to my OnePlus 3 and removed TWRP as a side effect of my attempts to recover from that situation.

To get TWRP back, I installed adb and fastboot on my laptop running Ubuntu 16.04. I tried the packages adb and fastboot as well as the packages android-tools-adb and android-tools-fastboot. Same result in either case.

If I boot my device up (system is still on it but I can't unlock the device) while my phone is connected, my laptop shows me 2 devices. One is the device's data (which I can't access because I can't unlock the device) and one contains among other files a configuration file for adb. I ran it after it didn't work before stumbling upon it and running it but it still doesn't work in exactly the same ways as before.

Here is part of my console history:

```<code>christoph@christoph-laptop-16-04-2:/media/christoph/OnePlus Drivers$ sudo adb connect
Usage: adb connect <host>[:<port>]
christoph@christoph-laptop-16-04-2:/media/christoph/OnePlus Drivers$ sudo adb reboot bootloader

christoph@christoph-laptop-16-04-2:/media/christoph/OnePlus Drivers$ sudo adb sideload '/home/christoph/Downloads/twrp-3.0.2-0-oneplus3.img'
Total xfer: 0.06x
christoph@christoph-laptop-16-04-2:/media/christoph/OnePlus Drivers$ sudo adb reboot
error: device '(null)' not found
</code>```

The line where it says Total xfer: 0.06x in the output was executed after going to the sideload option in the recovery. Doing a sideload there is the only thing which appears to work.

The 2 line above it (the fastboot ones) and the one below it were executed in that mode, too. The first 2 were executed while the device showed the lock screen. And the rest was executed while in fastboot or recovery (I don't remember but they seem to behave the same way).

Starting out using sudo turned out to be unnecessary and to create a .android folder located in my home directory which only root can access. I deleted it, purged the packages mentioned above, and tried it as normal user executed the configuration script as a normal user, with still the same behavior.

Main question: How do I get TWRP back?

Overriding question: How do I get access to my phone back preferable after reading the SD card so I can retain my data?

Sub-Question: Why doesn't any of the commands work, except one in a special mode?

I suspect the last one has to do with my phone not knowing about the public key which has been created by adb and stored in ~/.android but if a public key is needed to be authorized to make changes to the phone by default and to issue an authorization requires a working and accessible system, that seems like a bad setup for something you can't just boot a live system on and chroot into the installed system from there.

Regarding the likely-to-be-posed question of how I got TWRP onto my phone in the first place: I don't remember. I remember that I once got my hands on a Windows machine because I didn't manage to do something that had to do with adb/fastboot on my Linux computers and ran some graphical software to get the job done but I don't recall whether that was about my OnePlus 3 or my Nexus 4. I currently have access to a Windows PC via an admin account if I ask nicely, for about the rest of the week. After that, in regards to having elevated privileges, it's back to 4 computers (which means that I should be able to rule out connection problems due faulty USB hubs or configuration mistakes) which all only run GNU Linux operating systems, but I have restricted access to Windows machines at uni. Edit: I remembered that my laptop came with some kind of windows (I think it's either Windows 8 or 8.1) but I removed the HDD right when I got it. I still have it and am currently where that HDD is and can take it with my to plug into my laptop in case I need a Windows with admin privileges.

问:
How do I change default apps used from the Google drive app on Android 6.0?

How to disable auto shutdown on low battery?
I'm using a custom ROM (danielpinto8zz6's Cyanogenmod 12.1 build for the Xiaomi Redmi Note 2, in case anyone is interested) and there's an issue with what I guess is the coulomb counting profile.

The battery drains incredibly fast under certain circumstances leading to a force shutdown. When I then remove the battery briefly and boot the phone up again it shows a realistic charge value instead (like 30% or even 80% depending on the circumstances). I guess removing the battery resets the coulomb counter and causes Android to rely on voltage only?

Anyway, is there any way to disable the auto shutdown without using the Xposed module? I can root the phone and edit the system partition -- I just don't want to keep it rooted afterwards.

Alternatively, can I force Android to always use voltage only instead of coulomb counting?


问:
Any way to circumvent Nexus carrier lock?
I have a brand new Nexus 5X locked to a Japanese carrier called y!mobile (run on the Softbank network).  They won't unlock the phone unless I open up a contract and stay with them for 6 mos.  This is not an option.

I tried two online unlocking services (simdoctor and sim-unlock) and neither of their NCK codes did the trick (they were identical, btw).

Prospects are not looking good.  I saw a reddit thread where someone suggested reflashing with a stock Nexus ROM.  I'm curious if this will be a waste of time, as I've read that the carrier lock resides nestled away on hardware somewhere unaffected by OS.  On the other hand, this phone, as far as I know, has no carrier-specific alterations whatsoever (other than the lock)--so I guess I'm holding out some hope the Nexus devices might be an exception.

Will re-flashing do anything for me?  Any alternatives you can think of?  Why are the brand-specific unlock codes choking on the 5X?

Thanks!

How to access internet behind proxy with authentication
Our University provides internet behind a http proxy. To use internet we need to go through a http proxy server (proxy address and port) with authentication (username and password). Also the external DNS servers are not reachable from our institute network. We have our own DNS servers (addresses known).

As Android does not have any option to use proxy authentication with Wi-Fi and moreover all the apps does not obey android proxy settings we usually used Drony. For a non rooted device it creates a local VPN (with proxy authentication) and compel all the apps to pass through the VPN to connect internet. Everything was mostly fine.

The problem begins with upgrades beyond Kitkat (Android 4.4). Drony stopped working. It is a robust app with lots of options. I made a few changes but not succeeded and now kind of lost. I have tried few alternate  apps for non-rooted devices like Psiphon (got large delay over network) and proxyauth (few apps do not obey its VPN) but their performances are not as satisfactory as Drony.

Could you please tell me how can I use Drony (setting details) in Android 6? Other way it will also be a great help if you suugets any app that can reach the internet through the above network settings for a non-rooted device.

Some apps' notifications disappear after half a second
I have an Acer T07 (aka Liquid Zest 4G aka z528) with Android 6.0. I got it for Christmas so I did not have the time to tweak it for now !

Whenever I recieve an SMS, a notification does show up, and then disappears after half a second. This is particularily annoying since I am not always looking at my phone and when I check it I see no notification. Then, I open the SMS app (currently using Pulse SMS but the same happened with Textra and basically any alternative SMS app - tried a lot of them) and see unread messages I was not aware of. However this problem doesn't happen with the stock SMS app.

I thought this was just with SMSs but from time to time the phone vibrates and when I turn on the screen to see what's hapening, I see nothing - which is certainly because a notification arrived just to immediately disappear.

I don't have a list of the application that do this mostly because I never see those notifications. Apart from SMS, I use very few apps that generate notifications (no social networks or similar apps) so it's hard to tell how many apps have the problem and what they have in common.

I found no one with the same problem by googling it and neither by searching this SE.

Any help on how to fix this weird problem is highly appreciated !

Thanks :)

EDIT : I found out that Discord app does it as well. I also found out that some notifications don't even show up, but just make the phone vibrate without letting me know at all what app it comes from.


问:
Best way to play a long audio file cleanly
I have a 12 hour audio file that contains ambience that I listen to while sleeping in noisy places.  My old phone running Android 2.something can play it without problems using MX Player.  My newer phone, a Galaxy S4, running 4.something, can play it with MX Player but it will occasionally glitch, causing the sound to drop out for a moment before resuming.  This wakes me up and is thus unacceptable.  At this point this is about the only use I have for the old phone and I'd like to stop using it, but I need this functionality.  The other apps I tried seem to hang on the file's long duration or size (500MB).

I'm not sure if the glitching is due to MX Player or if other phone processes are interrupting the sound access or processor usage.  Is there a better way to play large audio files?  Or is there an app that can seamlessly loop a shorter audio file?

Galaxy s2 stuck in flight mode
I am attempting to unlock my old galaxy s2 without needing to reset it. My original plan was to get the pin wrong 5 times, then unlock using google account. However, when I inserted the sim card I turned flight mode on to make the phone reset its network and use the sim card. it got stuck there. It would not let me press the flight mode button again, so I rebooted it.

Now the device says flight mode is disabled in the power menu, but displays the flight symbol in the notification bar.

There are two possible ways I can think of solving this. Firstly, if anyone could please suggest any way of fixing the flight mode problem I am having.

The second solution is I have the apk of screen lock bypass pro on my pc, but I haven't found a way of installing it on my phone from my pc as the phone is not connected to the internet and apowersoft's phone manager didn't actually install it.

`/data` and `/sdcard` use the same block device?
My OnePlus 3 is in a pretty weird situation. I deleted the contents of /sdcard on an adb shell while my phone was running TWRP via:

```<code># rm -r /sdcard*
</code>```

I also deleted the hidden files files but they are in a different tar ball than the non-hidden ones and are already restored. For this, I pushed their tar file to my phone and extracted it in an adb shell. However, pushing the substantially bigger tar ball of non-hidden files over to my phone failed.

Upon investigation, I found that apparently /dev/block/dm-0 is mounted both in /data and in /sdcard:

```<code>~ # df -h
Filesystem                Size      Used Available Use% Mounted on

/dev/block/dm-0          52.7G     36.9G     15.7G  70% /sdcard
</code>```

The contents of /sdcard don't make up for 36.9 GiB. It's only TWRP (a few GB) and the hidden folders (about 1 MB).

```<code>/sdcard # ls -la

Why is this?

When I looked for what took the storage space, I found that there are files which used to be on the (emulated) SD card but which I deleted (which is why /sdcard is so empty) before trying to push the tar ball over to my phone:

```<code>/data # du -h . | grep '[0-9\.]\+G'

What can I safely delete? Can I wipe "Data" in TWRP without apps malfunctioning? What happens when I delete the contents of /data/media? Are those hard links of the files I deleted on /sdcard?

I pushed that tar ball several times over to my phone, today, extracted it, deleted it, messed up, deleted the contents of /sdcard, and started over. However, this time, which thus far appeared to be the last time, such weird behavior occurred.

Edit: This question was closed as a duplicate but linked question is entirely different. Just like... Read my question before you close it, please? The linked question is about someone who doesn't know what a symlink is. Mine is about how it can be that data in two locations that have the same device mounted to them can have different contents. The question was closed by someone who doesn't know about symlinks nor about mounting.


问:
Device update lying about wifi access
I have a Samsung tablet running Android 5.0.2. Since roughly the new year it has been reporting a system update available.  It took me a few days to clear off the 270MB its asking for, but I've done so. However, when I try to update it through About device -> Software Updates, it reports failure due to my network not having Internet access.

I'm typing this on the tablet right now, and I assure you I'm not using elfin magic to move the bits to the SE server. Clearly its Internet access is just fine.

Has anyone else seen this before and / or know what's going on here?

Why can't I fastboot flash TWRP?
I have adb and fastboot installed, but when I got into fastmode on my Zenfone 2 Laser it won't list the device anymore.

I am using Ubuntu and the adb/fastboot seem to work just fine in the terminal. However when the phone is in fastboot mode it is lost from the list. Debugging is on too.

Basically I am trying to do this: https://forum.xda-developers.com/zenfone-2-laser/general/guide-marshmallow-root-guide-ze500kl-t3380461

I am trying to boot TWRP without flashing the phone, so that the bootloader and SuperSu could be installed.

It is not on their website, but I can't believe they have skipped making a ROM for this device.

It looks like none of the official releases support this device. I really don't know why though.


问:
Google play voucher option displayed for in-app upgrade but not valid after all
I just wanted to buy the pro version of an Android app (Memrise). The Pro version is not a separate app but an in-app upgrade function.

So I chose my preferred subscription, and the usual Play Store dialogue popped up and asked me to choose a payment option. Since I got a 50 Euro voucher I chose the option "Gutschein einlösen" ("redeem a voucher" or something similar in English). So I typed in the code and my payment validations and the cash transferred to my account. But before I was able to complete the transaction the Google Play Store told me, that a voucher is not a valid option to pay the app upgrade.

So why was there the voucher option in the first place if it is not a valid option? I have no use for other apps/music and stuff except for that specific upgrade. Is there a way to get the upgrade / the money back anyway or are the 50 Euro just gone?

How to find the right ROM to unbrick device
I forgot to enable the OEM unlock while rooting a Galaxy Tab A 280 following the guide at XDA-developers. Now the phone is only displaying a FRP error on boot and shuts down again.

Download mode is working, but needs the correct ROM. I downloaded one ROM from sammobile, but installation resulted in the same error.

Where is the correct ROM to download? (Or is it possible to OEM unlock in this state?) If it helps, the serial number is R52H81KCSVW.

How do you edit the hosts file on rooted Nougat
I have a Google pixel xl that I have rooted. On my G3 I was able to use Hosts Editor (https://play.google.com/store/apps/details?id=com.nilhcem.hostseditor) without any issues. When I tried on my xl I can see and accept the SU request but the hosts file does not get modified.

I then tried manually editing it with a text editor and I've confirmed that it's modified but using Chrome I still get navigated to the old original website.

I have a test server in my home network and I'd like to be able to use my phone to hit the test site instead of the live one.

Is there something special in Nougat that is making this not work?

问:
How can I decrypt / move the adopted storage from my SD card?
Apparently the SD-card in my phone was a fake. It reports 32Gb, but it only seems to store 16Gb.

Now, I had that thing in my phone for a couple years now, it worked great, but this morning my smartphone reported that the SD-card was missing and I should put it back in. I'm on a non-rooted device, and according to this answer I need the decryption key if I want to get my data back. Now I'm stuck with half an SD-card, unable to get that key.

Any ideas?

Chrome bookmark on home screen to BBC News opens as webapp
Using my Samsung Galaxy Tab3 10.1 (4.4.2) I have just started using Chrome as the default browser instead of the built in "Internet".

I have recreated many of the bookmark links on the home screen without issue, and they open Chrome as expected.

However if I open http://www.bbc.co.uk/news and then "Add to Home Screen", the bookmark opens Chrome as a webapp meanng there are no tabs or any ability to use it like a normal browser.

How on earth can I stop it opening as a webapp, and make it open as a normal tab?
