DeadSystemException causing Google Pixel power cycling?
I am getting this error when my phone is power cycling randomly without my control. See below for previous error logs.

```<code>06-09 11:47:24.470 1379-1379/? E/AndroidRuntime: FATAL EXCEPTION: main

Back story:

I bought a Google Pixel online recently, and I've had an issue with it power cycling randomly.

I've followed numerous online help and suggestions from sites such as here. Here's my experience

The phone will operate normally for a week or so, then go into waves of power cycling very frequently

Safe mode stops the power cycling

A factory reset will cease the power cycling, I've done this once and assumed it had fixed it, but the issue has returned today.

I've done some android app development before so I booted up android studio to see if the debug logs could reveal the cause of this issue.

Here's the logcat debug logs pastebin.

Sony Xperia Z3 D6446 Touchscreen not working right on bottom
My xperia touchscreen got physically broken. I got it to a "tech service" so they promised to use an original piece and change the old damaged display with a new display.

After they changed (many other hardware things like camera button and gsm antenna where damaged), the touchscreen aparently works ok, but, I noticed that, until I tap closer to the bottom of the screen, my taps get misplaced. I can verify it with the developer options.

I tried changing the resolution, density and overscan via adb shell with multiple values, but the effect is almost the same, it seems the installed  display doesn't have the right behavior.

I've tried like 20+ touchscreen calibrator applications (like 3 different languages) to solve this problem, and still persists.

I restored to factory, installed custom external ROMs, even installed ISP custom ROMs and nothing worked.

I've run the test for the touchscreen and I can use all the screen without a lose.

Hope someone can lead me to a possible solution, maybe a way I can play with those 3 values so I can "emulate" the correct position of my taps. Ideally, a way to "not enlarge my taps" while I get closer to the botttom of the screen.

How to fix "Google couldn't verify this account belongs to you"?
O.P.
I switched phones and I cannot login to my account on the new phone. It keeps on giving me the message above.

Weird thing is that I'm still login in my Samsung tabtet. I was able to get some code to verify my identity but I was never asked for this. I was never asked to verify using my phone or Google authenticator either.

The best I got from the AWESOME Google customer service is that they'll get back to me in 3-5 days.

Any ideas on what else to do?

How to root blackview a20
I have a blackview A20 which is a low spec phone running android oreo go.

I would like to use this phone for experimentation with android development and learning about android on a cheap device without risk of breaking my main phone. To do this I would like it rooted and as a bonus with a custom recovery so I can test custom ROMs.

State of device:

Unlocked bootloader

Unchanged ROM

Unchanged Recovery

OEM unlocking enabled

USB debugging enabled

What I have tried:

Flashing recovery images with fastboot

Using fastboot flash recovery recovery.img with some TWRP and CWM recovery images all yield:

```<code>target reported max download size of 134217728 bytes
sending 'recovery' (4690 KB)...
OKAY [  0.169s]
writing 'recovery'...
OKAY [  0.276s]
finished. total time: 0.448s
</code>```

or similar. Then I restart phone and select boot into recovery mode. The phone hangs for a small while before restarting and booting into the normal OS. On restart into recovery the unchanged recovery is there still.

Various 'one-tap' methods

All of which were unsuccessful. If needed I can give details.

Installing SuperSU zip from recovery

In a futile attempt I tried to use the android recovery to push a SuperSU zip with its update from zip option. I knew this wouldn't work but I found something interesting. On the Apply update from SD card option I get an error saying couldn't mount /sdcard

Booting recovery images with fastboot

I have tried the fastboot boot recovery.img command to try to boot directly into the images. I get this

```<code>downloading 'boot.img'...
OKAY [  0.211s]
booting...
OKAY [  0.047s]
finished. total time: 0.261s
</code>```

output but the device just restarts and boots normally into the normal OS.

What I would like from this question (In order of importance):

A way to root the device

A way to access a custom recovery (even if temporary)

Ability to install custom ROMs

A permanent custom recovery

How to set two different sound levels for two different sounds played simultaneously from two applications?
I'm using Poweramp Music Player (in the background) to play music, and MX Player (in the foreground) to play videos (video lectures). What I'm looking for is to play music in the background with a specific (low) sound level (or volume level) while playing videos in the foreground on MX Player with another (higher) sound level. I'm able to play two sounds simultaneously by disabling Permanent Audio Focus Change (in Audio Focus ← Audio in Poweramp, hinted by this question) but without being able to set two different sound levels for the two sounds (The sound from Poweramp and the other one from MX Player) as there is only one generic sound level for everything on the media stream that all apps abide to.

How could I set different sound levels for two simultaneously played sounds from two different applications?

Suggestions tried but unsuccessful:

I've tried App Volume Control, but it says:

It's not possible to have a background app and a foreground app with different volumes, this is an Android limitation.

Notification bar too dim on Galaxy S7 with Oreo
Last night my Galaxy S7 got an update that included upgrading to Oreo. I don't know whether the problem is specifically because of Oreo or if there was something else in the update that caused the change, but the notification bar at the top of my home screen is now uncomfortably dim:

There's also a larger version if it's tough to see. It might not look that bad, but it's clear that there's a difference between the grey used by the notification bar and the white in the text and background of the Gmail app and with my eyes looking at my phone's screen that difference is a big deal. The same grey seems to persist in most apps, though apps with a white background instead show a darker grey. Is there a way for me to make those icons white instead?

Then, I did some search online to bypass the google account and successfully achieved it by using the talkback and quick shortcut maker method.

Android 6 - cannot enter recovery mode
I'm hoping someone can save my sanity here.... I'm trying to install a new firmware on my daughter's old Android device - a wonderful Doogee X5 Pro. I really want to install some new firmware as this device is one of those that's sold on Amazon that after a week or two of every factory reset gets unwanted adverts popping up all the time.

When I hold volume down & power I get to a "factory menu" but the recovery option isn't there. When I hold volume up & power there is a recovery option but all I get is the android on his back and the phrase "no instruction". I have finally managed to get that ADB stuff installed but that tells me the server version doesn't match the client...

I have tried SP Flash thing but I found the whole process very confusing and it didn't work. I've tried a couple of rooting programmes off the internet but they both failed.

I have a little recovery file ready that if I can get to it via recovery will root the device and allow me to install what ever I want. I have two firmwares ready to rock & roll....

So if anyone knows how I can get the recovery option back on the factory screen or resolve the issue in ADB I'd be very, very grateful. Or point me in the direction of a website with instructions on either.

Apologies if this sort of thing has been posted many times before.

Thanks,

How to disable Developer options on Moto E4 without clearing settings storage data?
In order to speed up my Moto E4 (Android 7.1.1), I followed this advice:

Settings > About phone > Build number (tapped about 3 times) which enabled Developer options. Then hit the back button >  Developer options.

One by one I opened three animation scales and brought them down to .5x:

Window animation

Transition animation

Animator duration

Then at the top of the screen I turned Developer Options off. However, it is still available now in my settings menu when previously it was not (before I hit "Build number" 3 times).

When I did this I didn't realize that I was opening a mode that wouldn't just close back when I was done. In searching for how to disable what I enabled, I read that I can disable developer options (remove it from the settings menu) by going to:

Settings > Apps > Settings > Storage > Clear Data

However, I am hesitant to do that because it says:

```<code>All this app's data will be deleted permanently.
This includes all files, settings, accounts, databases, etc
</code>```

I'm not sure what files are included and how that will affect my phone.  It's only 700 kb though.

Is there another way that I can disable/close the Developer options that I inadvertently opened? If not, how can I know what the affect will be when I clear the settings storage data?

Thanks!

How to print from a browser in an android device
So, here is the situation: We are a SaaS company, our contractor haves multiple Zebra phones and Zebra printers, they want their salesman to be able to go to the place where they sell their stuff (they are product providers), and make an invoice in their phone, then print it and give it to the person in charge of the place.

I want to be able to print the invoice from the browser (since our software is a web app), the printer is attached to the android device with Bluetooth, there can't be any dependence to computers (so I guess I can't use Google Cloud Print) and it shouldn't be a long process, it should be efficient.

I also can't pay for printing apps, I downloaded lots of them and either they don't work, or they ask you to pay after certain amount of prints, if it's needed, we can develop an application to connect the printer with the browser.

Printer: Zebra iMZ320.
Android version: 7.1.2 (Nougat).
The browser they use will be variable, we can't develop something just for certain browser, it must print from ANY modern browser.

Thank you in advance.

Steam doesn't work over tethered wifi through an android phone, how do i solve this?
So i tried to use my android phone that is connected to a wifi, and used a wifi sharing app called (Netshare), to tether the internet to my mac(wirelessly). The internet worked, the browser works and i can even go to the steam's website through my browser, but when i try to open the steam app it says its not able to connect.Any workarounds?

Ive tried to look for solutions but haven't found any yet. But AFAIK this likely seems to be the problem with UDP ports(which steam game clients require supposedly)and which the app doesn't seem to provide(thats what i think).

I mean, as i run the hotspot the app creates another network named "something", and tells me to connect to it and configure the HTTP and HTTPS proxy on my computer with 192.168.49.1:8282and thats all. The internet does work but things like downloads and steam login doesn't.

Trying to perform ADB Backup but it prompts for a password
I am trying to perform an ADB backup but I got stuck at the step where the phone receives the request of backup from the computer (the command I used on ADB was

 adb backup -apk -shared -all -f F:\Android backup.ab).

It is asking for a password as in the pic below (sorry my phone is in Chinese, I will translate the dialogue below):

'The system has received a request to backup all data to the computer; do you allow this action?

If you did not request to do so, please do not allow this action.

Your phone has been encrypted, therefore you must encrypt your backup. Please enter password below:'

I actually forgot that I ever encrypted my phone; and I certainly don't remember having set a password for the encryption (I use the unlocking pattern in daily operations). So I thought this is to set a password for the backup action.

But as you can see, I typed some words in, but the 'Backup your data' at the bottom right button just wouldn't respond no matter how many times I pressed it. (I pressed the 'Do not backup' button next to it and it quit instantly, so I am sure the screen is reacting to my touch alright)

Would anyone mind lending a hand please? Thank you so much!

Open Source "My QR code" app to quickly share my contact details?
Especially in Japan/Korea, there are many proprietary apps to quickly share your name+email+phone. Example here. They all work the same way:

At first use, enter your name, email, phone: It generates "your" QR code.

Whenever you meet someone and want to keep in touch:

Launch the app, it instantly shows your QR code

The other person scans it, and can add you as a contact without typing anything.

Key features:

Extremely fast, should take less time than a web page load.

Fit to screen size for easier scanning, maybe even make the screen brighter temporarily.

Options to show a different QR code for carriers that use a special format.

QUESTION: Is there an Open Source app that does this?

If not, I might create one, but I prefer to ask first.

Almost nobody uses Bump here in Japan, making it pointless.

问:
How can I access the contents of the main disk on my Android device, for data recovery purposes?
I'm trying my best to determine a method of recovering some deleted data on my Samsung S5.

I've used tools such as Recuva in the past to recover files on flash drives and devices of that nature. However, when plugging my Android device into the computer, it seems I can only select options such as Charging, MTP, etc - none of which actually assign a drive letter to the device and therefore make it impossible to run these recovery tools. I see USB Mass Storage used to be an option, but appears to have been removed from the Android OS at some point.

The device was accidentally wiped and reset. It is rooted with SuperSU installed, and I've been taking special care to not use the device so I can avoid overwriting data. I've tried multiple Android-specific recovery tools, though they either don't recognize that the device is rooted or never prompt for root permissions, and therefore haven't been of any use.

My question is this:

Is it somehow possible to mount the device as a drive so that I can run recovery tools against it as I would a flash drive.

Otherwise, is there some way to mirror the entire disk so I can run recovery tools against it separate from the physical device?

Thank you!

Update

I've figured out how to make an image of the disk, I believe (it's a 14.7 GB image, and the internal disk is only 16GB, so I'm thinking I imaged the right partition), and that seems to be some progress. I did the following:

adb pull /dev/block/mmcblk0 mmcblo0.img

Now that I have this image, I've tried scanning it with a tool called Autopsy, but I don't see many deleted files listed. How should I proceed given an image of the disk?

i have recently bought a Samsung note 4 sm-g910H  (at least that what it says in the settings)  but upon opening it up i noticed that the USB module had sm-n910F typed on its ribbon connector ,and after lifting up the motherboard i noticed sm-n910C typed on the motherboard , is THIS normal , and if it is !! could i possibly flash a n910C ROM on the device because i am having issues with all sorts of connectivity on the device
1- Bluetooth restarting itself every like 5-15 minutes only when  connected to a WiFi network.
2-error when trying to tether my phone to a computer.
3-extremely weak reception.

问:
SIM IccId - logged anywhere?
Is there anywhere I can find historical traces of the IccId? By that I mean, something to indicate the identity of the sim card at some point back in time.

Ideally, this would be as far back as possible. Any "recorded" instance of IccId would be of relevance - system logs, attributes in SMS or call log - anything, really.

I doubt the background is relevant, but if anyone is curious:

In the peculiar case of my carrier disagreeing with what my SIM card's IccId is (and as a consequence, I assume, which physical sim card I actually possess) I've experienced the following:

I read the IccId off of the physical card, let's call this number 123.

When I ask my carrier for the PUK code, the response is an IccId (let's call it 456) and a PUK. 456 is different from 123 (very different - it's not a typo or anything) and the PUK (naturally) doesn't work on my sim.

When I say that IccId 456 is not the number that appears on my sim, seemingly nobody is able to figure out why they're showing an IccId for me that isn't the sim that I physically possess.

I've spoken to 3rd level techs and they say that IccId 123 was produced a year ago, but registered to the network only a week ago (despite having been in my phone for well over a year)... but is not and has never been in "actual use".

They also say that they see activity from IccId 456 consistent with the activity I've relayed to them.

I've used my phone without significant issue (the only issue being that I was unable to get a form of mobile banking authorization based on a Sim Toolkit-equivalent, and I'm now guessing that this must be significantly related to the IccId disagreement) for the past year, so any notion that my sim card hasn't been in use, or registered prior to a week ago, is empirically untrue.

The phone is a Huawei Honor 8 (FRD-L09, bought in Europe if that matters). It is not rooted so I would prefer non-root approaches (though root approaches are still welcome).

Motorola G4 random no internet via WiFi
When connected to WiFi at home, my Android phone randomly says there is no internet connection with the WiFi and it switches to 4G. There is no notification of this. An exclamation mark will be shown in the WiFi icon. However, reconnecting to the same WiFi solves the problem, until the next moment the WiFi is 'not connected' and that moment can take half a day or just a couple of minutes. The WiFi signal is excellent. It doesn't matter if I connect to 2.4 or 5ghz.

Now this could be a connection with my modem at home (modem is for internet, routers are connected to modem for WiFi), since other android devices (Samsung) do not have that problem. I've also tried to connect to other routers at home, but I get the same problem. I also don't experience the problem at other WiFi connections. AFAIK there is no option to not fallback to 4G when WiFi is not connected. Other than check my modem again, could there be a different approach to solve this problem?

How do I log in to Android Messages for Web without my phone?
I recently discovered the Android Messages for Web service! My immediate thought was, awesome! If I forget my phone at home, I can still text when I'm at work. In an emergency, I could send a text message using a friend's computer.

However, when I logged in, I discovered that I needed to use my phone to log in by scanning a QR code on my computer screen. I'm afraid that this defeats the purpose for me.

(I'm aware that it has a "remember me on this computer" feature so it will work in some cases when I don't have my phone with me, as long as I've recently logged in on that computer with this option enabled. But this is not all computers at all times, so it defeats the "in case of emergency" situation.)

How to disable auto update Google Play Store and Google Play Service
My phone broken WiFi (couldn't scan WiFi around). So, I have to use phone data. However, I'm having problems with two apps: Google Play Store and Google Play Services usually updating, consume a lot of phone memory, and use more and more network data (I pay a lot of money for them).

问:
Lineage OS -- Phone still spying on me?
I switched from Android to Lineage OS, and I installed the most basic Gapps package possible, called 'pico', to get the bare minimum requirement for the Google Play store. I then manually disabled Google Play services. If I want to get to the Play store, I have to manually re-enable this.

Recently, I was in the car with my wife and son, and I mentioned that I miss the funny vines that were produced when vine.co was still active. Then, when I got home, I connected to wi-fi, went to Youtube.com through a mobile browser (I don't have the app installed), and the homepage was showing my 'funny vine compilations'. I was not searching for vines before this.

Then, today, I was telling my wife that we need a better vaccum cleaner, and that we should order a Dyson on Amazon. An hour later, I went to Amazon.com on my phone and the home page showed a deal on Dyson vaccum cleaners.

The reason I went through the trouble of putting a custom ROM on my phone was that I didn't want my phone listening to me. I'm not logged into my Youtube or Amazon accounts on my phone, and I didn't search for these things. I suppose it could be a coincidence, but I highly doubt it.

So my questions are: how is my phone spying on me? And how can I prevent this?

How can I flip or mirror the entire screen display (have root)

I found this page with people talking about a tablet that was malfunctioning in the manner that I am hoping to achieve, but there wasn't much info that would help me do this on purpose.

I'm hopping for some low level setting or flag somewhere on the system that I can change with root that will flip the whole display for me.

How can I see my notifications only every hour?
Let me apologize in advance for the bad title, but I didn't quite know how to describe it. What I want is a way for my phone to only show me the notifications from time to time instead of showing them to me as soon as they pop up.

So instead of showing me the notifications from every app as soon as they appear (which is the default) I want a way for Android to keep them hidden and just show, for example, all the notifications for the last hour at once. Then an hour from then it would show me all the notification from that hour, and so on.

I have looked at ways to do this using Android settings itself and I've looked for apps that do that, but no luck. Is there a way to do such a thing?

Thank you.

IBM Verse Inbox not syncing
Our organization is using IBM iNotes Social Edition and have set up a server for emails. I have been using IBM Verse for my emails syncing on my mobile Samsung Galaxy Note 4. It was working fine till last two months. Suddenly, on my Verse app, all emails are being synced except my Inbox. It is not anymore syncing. I have tried many times to get the issue resolved from my Email administrator but the issue persists. The thing that is to be noted here is that Inbox emails are working fine and notifications of my Inbox email arrives on a Web browser. But I am not able to sync it on mobile. All emails are synced on mobile except Inbox which remains empty and no notification of arriving email as well.

Also, note that the emails in apps of all other employees are working fine. Secondly, our mobile emails are synced on a different server as compared to the main server (for web browser emails), they are using some kind of server mirroring (for IBM Verse).

What have I tried:

Reset and reconfigure IBM Verse Reinstall and reconfigure IBM verse

Installed IBM Verse on other device and configured

Reset the device and reinstalled IBM verse and reconfigured

Requested change of password from email administrator, and reconfigured IBM Verse

None of the methods works to bring my inbox back to sync on the mobile device.

SD Card as ADOPTABLE STORAGE isn’t recognised anymore
Hello EXPERTS,
I have somehow messed up my phone and require some help to get it back working as many information and data are suddenly not available anymore.
Before someone tries to explain me the importance of a backup, so be assured, that I run backups regularly, however since my storage was full and I didn’t purchase more of it, some data wasn’t backedup.

This is my situation and I would really need some „positive motivating feedback“:

I use a SAMSUNG GALAXY S7 rooted with NOUGAT 7.0

I use a 256 GB SD card formatted as adoptable storage

two days ago, I wanted to copy some data to a colleague and inserted his SD card, which was formatted as portable storage into my device. I copied the 2 large PowerPoint Presentations and when I swapped the SD cards again, my phone didn’t recognise anylonger my own SD card.

A message: „Unsupported SD card“ is shown and „This device doesn’t support this SD card. Tap to set u...“

The swap of the SD cards was done while the phone was powered off and on again.

Let’s assume please, that the SD card is undamaged and that nothing happened to it while it was removed around 10 min from my device.

My phone still has some data available and I am not taking at this stage any pictures or installing any apps. So all key information about the adoptable storage should still be on the device and on the SD card.

Please let me know the steps, how I can connect again my SD card to my phone, allowing my phone to recognise my SD card again as his adoptable drive without that I need to format it and loose data, which is not included since the last backup.

Thanks a lot!

How do I get split screen apps to both stay active
I am trying to run 2 apps in split screen with both staying active at the same time. Most results on google are saying this is not possible and they blame the app for it not working. Below is some detailed testing I have done.

This is an android issue/setting, not an app issue. The reason I know this is because I have 2 phones both using split screen. One can/will/does keep both apps active at the same time while one pauses whichever one is not in focus. The apps are identical across both phones.

Apps for testing: Pokemon Go (Pogo) + Jurassic World Alive (JWA) (both AR games that use GPS and real time location constantly).

Phones for testing: Moto X4 and Xiaomi Redmi 5 Plus (I have previously tested on the Axon 7 and the Nexus 4-5-6, both behave the
same as the Moto X4 currently does).

Android versions: Redmi5 - Android 7.1.2 (MIUI 9.6.2.0) | Moto X4 - Android 8.1.0

One item of note: On the Moto I had to enable developer mode and turn on 'Force activities to be resizable' before either app could be
put into split screen. On the Redmi5 this was not needed as it was
already enabled.

Test method: Open Pogo normally. Use the 'intents' (app switch) button and at top click the section titled "split screen" (both
phones have slightly diff wording here). Drag Pogo up there and it
takes up the top half of the screen. In the bottom section, select
previously running JWA (or start it from home screen) and it will
take up the bottom section of the screen.

Wanted outcome (Redmi 5 Plus): Top portion continues without pausing and bottom game loads and works without pausing. Both apps
continue to run as if they were running in full screen and were
active

Unwanted outcome (Moto X4/Axon7/Nexus(4|5|6): Top app freezes
or pauses when you load the bottom app. To unpause it, click on it,
but this pauses the bottom app. Whichever app was last clicked on is
active.

Since the apps I am using to test are identical across 3 of the phones I am testing (never tested JWA on the nexus phones) this cannot simply be an issue with the apps not supporting it. There has to be some setting that Xiaomi or MIUI enabled to allow this to work.

Another note, I am not trying to get only these 2 apps working, but these are 2 I would like to have working and made for good test apps due to how they run.

I realize my ask here may be unclear. I want to know how to duplicate the functionality from the Redmi 5 Plus on my other devices (Moto X4, etc).

'Duplicate' edit: I do not feel like the question listed as duplicate answers mine other than "you cant", but obviously MIUI or Xiaomi did. Also that answer seems to point to some side effects I should be experiencing on my Redmi that I am not (apps not pausing when minimized/unfocused).

Samsung S7 Oreo upgrade decreased screenshots quality
I did this week the Oreo upgrade on my Samsung S7 device. When I'm now taking a screenshot, the file is in JPG instead of PNG and the quality is just terrible.

I really need to revert back to the higher quality screenshots, I'm publishing crops of the screenshots on my own website. I simply cannot bring to my users such bad image quality.

Had a look to the Advanced settings parameters, but nothing I can change except something called "Smart capture" which seems not related to my problem.

To demonstrate what I mean, here is a 100x100 pixel crop from Android 8 version and from Android 7 version. The left part of the image is the bad quality screenshot from Oreo, the right part is what I had before the system upgrade.

I don't care about the JPG or PNG format, but the quality is mandatory.

Any hints to set the quality back to the original ?

My Samsung Galaxy Note 4 has been continuously restarting during or at times right after the welcome screen. I have tried the following steps to sort out this issue:

Downloaded Samsung USB driver and installed it.

Downloaded Odin version 3.12.3.

Downloaded firmware for my Note 4 SM-910F from SamMobile.com .

Delete the cache.img.ext4 from the firmware .md5 file before flashing it with Odin. (Is this a good practice?)

Once the firmware is loaded in Odin I turn on my mobile phone and set it to download mode by pressing Home+Power+Volume Down button.

Once Flash is completed I restart my mobile by taking out the battery and then press the Power+Home+Volume Up button together to get to the recovery screen.

Once in the recovery screen I wipe the cache partition and data/factory reset as well. During the data/factory reset process a verify dmverity hash tree... comes up and then my mobile goes back into the endless restart cycle.

While in the Android recovery menu I have noticed that right at the end it's written: dm-verity verification failed.

From this point onward though I feel I have done everything by the book and my mobile is still restarting continuously. This is the first time I have dealt with such a problem and I am new to the whole process of flashing the firmware itself.

Phone won't connect to internet in the background! Why?
My phone (Galaxy Note 4) running Android 6.0.1 can't do anything internet related unless the process is running in the foreground. I've been dealing with it for so long, but now I'm stuck in the hospital after serious surgery for the second time and I really would like it to work this time... :(

This is the error script, from leaving Facebook in the background to post a video. My phone isn't rooted or anything so it's the best I know how to offer:

9zf caught Execution Exception, com.facebook.tigon.tigon utils.TigonErrorException: TigonError(2): TigonLigerErrorDomain(2) AsyncSocketException: con-nect failed, type = Socket not open, errno = 111 (Connection refused) java.lang.RuntimeException: 9zF caught Execution Exception, com.facebook.tigon.tigon utils.TigonErrorException: TigonError(2): TigonLigerErrorDomain(2) AsyncSocketException: con-nect failed, type = Socket not open, errno = 111 (Connection refused) at X.9zF.D(1746707) at X.9zF.iyA(1746720) at X.24s.run(:497658) at java.util.concurrent.Executors $RunnableAdaptercall(Executo
  rs java: 423 *

{facebook cut the rest off, but the next line, I think, is this}

I'm tech savvy but not this tech savy. My phone will do nothing internet related in the background, nothing. Whatever it is, as soon as it's not running in the foreground, it zonks out. Screen turning off drops my calls (I use an internet number), messages aren't delivered unless I open the app, etc etc Messenger (for Facebook) in particular acts really funny about connecting; after it zonks out and I reopen it, I have to disconnect and reconnect to the WiFi or it'll just sit there telling me I have no Internet. Other apps basically do that too, though. Everything was the same even when I used to have phone service and mobile data, switching between them, I believe, would fix it too.

Not sure how relevant this is, but my phone totally rejected being rejected to "sign in" (I quote because it claimed I needed to sign in in my settings, but just wanted to redirect me to the hospital page before it would work) to the public WiFi network here, and it always has silly little troubles like that. It kept saying Google refused the connection or giving me the generic dinosaur error. Everyone else seemed to do fine with it, finally after a million times of trying things, going to Google.com manually did work.

I disabled a lot of system components once upon a time because there are a lot that i just do not need ever running on my phone and wasting my battery. My best theory is I selected one (maybe even more) accidentally and caused this but I have no idea which one. My fear is some kind of virus/hacker/personal data stealing something or other hiding in my phone. I used to install modded versions of applications from the internet because I'm a fool. This is a pretty old phone, my non-stone-age one is broken.

I also bought it used and clearly very refurbished (not even well) from a sketchy auction on eBay, so that's another reason I'm concerned. It's probably nothing, haha. My device status claims to be official, I couldn't find anything particularly sketchy in my phone's information.

I don't remember when this started happening but I feel like it wasn't after disabling anything or I would have noticed? I'm probably wrong, though lol

Thanks in advance! ♡Quinn

问:
Is phone call quality different depending on the connectivity standard?
I've been trying to figure out how to achieve the best audio quality in phone calls, and part of it is finding out whether GSM, CDMA, LTE or other standards/technologies compress the audio the same way or differently depending on the phone's settings or hardware. I'm not asking about internet audio calls (like using Skype for example) but regular built-in phone calls.

Does the available network type determine the audio quality of phone calls? Can I improve the sound quality if I get a phone from a GSM or CDMA carrier? Does LTE or some other more modern standard improve audio quality significantly?

How to know power consumption at the moment?
From time to time my Samsung Galaxy S7 is starting to consume a lot of power, turns hot and eats 10% of charge in minutes.

If I have less than 10% charge, it kills itself even if on external power.

How to trace which application does this (and eliminate it)?

I tried GSam battery monitor, but it can display per application data only in average from last full charge time. I.e. it can't trace proccess which worked only minutes.

Are there any applications, which can trace simultaneously per time and per application?

dload:update partition MBR failed Huawei Honor 3C
I have Huawei Honor 3C H30-U10, It was running fine but some days back when I plugged in charger it restarted and hung up on welcome screen*(no animated logo)*. Seems like I need to install Stock Rom to it.

Phone Details:

Huawei Honor 3C H30-U10

Build Number:  H30-U10 V100R001C900B108

International Variant

I download Stock ROM for it with version B108 but it was in SP Flash Tool format. My phone isn't recognised by my laptop even though I have VCOM drivers installed.

This force me to think I need to download Stock ROM but which is in dload and UPDATE.APP form. It was hard for me to get any ROM H30-U10 V100R001C900B108 in UPDATE.APP form. Fortunately I got one from here (Please look at: 7. V100R001C900B108 ROM (update.app))

Upon pressing
Volume UP+Power Key It successfully went to updating from SD Card but I am receiving this error log on screen:

My question is

Why I am getting this error?

What are the other possibilities that
I can do to bring back this phone to life?

PS:

Pointing to this dload:update partition MBR failed Shopkeeper (Mobile technician) told me your phone internal memory is full, or corrupted. You can't get it right until you change the hardware part associated with memory. Is he right?

Guys, I tried hard to search this question on internet and I didn't find anything. Please provide rich information so that other community use it for reference.

PSS:

By going to wipe cache partition it says:

```<code>-- wiping cache

But by going to option: wipe data/factory reset it says:

and stuck. No further process at all.

MTP - it just won't work
Dear android enthusiasts!

I'm not sure this is the right place to ask but I'm being really desperate and out of ideas what to try. I have a Galaxy S6 Edge (SM-6925F) running Android 7.0 (Kernel 3.10.61-13115714). The problem is: I cannot access the phone via USB anymore.

It used to work until a few months ago. It stopped working on one computer, some time later also on all others. When I connect it to a USB port, it charges just fine, but does not display any USB options that would allow me to select what it should do (the connected for charging notify doesn't even pop up). Here is what I tried:

Standard answer is to enable the developer options and then enable USB debugging. I did that, no change.

In the developer options I can set what the phone should do when connected to USB. Changed from MTP to "charge only" several times, also tried the other options like PTP, even setting it to audio source for fun. Tried changing options and disconnecting/reconnecting, restarting phone, restarting host PC, just nothing.

Tried the *#0808# thingy. Again, this allows me to select the USB options but no matter what I select, nothing changes.

Other standard answer is drivers. Well, there is not much I can remove in my device manager as the phone doesn't show up anywhere. I don't hear a "USB device connected" sound, it doesn't try to install anything. I did try to uninstall and reinstall the drivers from [*], again with no effect. I tried Win7x64 and Win10 hosts. Nothing.

Changing the cable. Tried three different ones.

I'm out of ideas what else I can try, except for the full factory reset of the phone. I was trying to avoid that due to the hassle with reconfiguring everything. Therefore I was wondering if there are any other options or if I have to go for that.

Thanks in advance!

How to get memory dumps, when internal memory (/data partition) is damaged?
(Sorry for my english)
My phone, Samsung galaxy S3 16 GB wasn't rooted and installed custom recovery. Someday, it appears on the screen that "internal storage is damaged". So I want to backup internal storage, attempted flashing twrp and rooting the phone through CF-autoroot, but it unable to mount /data in twrp.

To create a internal memory dump, I find this article.

https://dfir.science/2017/04/Imaging-Android-with-root-netcat-and-dd.html

I tried to this.

```<code>adb devices
:: List of devices attached
:: 4300********061 recovery
</code>```

/data directory is empty.

```<code>adb shell
su
:: permission denied
</code>```

I think phone isn't properly rooted. Installing a supersu.zip from twrp, it says "install failed".

```<code>adb forward tcp:8888 tcp:8888
dd if=/dev/block/mmcblk0 | busybox nc -l -p 8888
nc 127.0.0.1 8888 > android.dd
</code>```

It created a dump file of 3.5 GB size on windows, although internal memory had 15 GB in use. And mounting the dump file from OSFMount is failed.

In this situation, is it possible to get a full memory dump of internal storage, specially /data partition?

Update.

Retry dumping of /data partition, and view this dump file from testdisk in linux. It worked.

Play store apps cannot write to external SD Card in Android Oreo
My Galaxy S7 edge recently updated to Oreo. Now play store apps no longer have rights to write to my external SD card. I have followed app instructions about how to open a system folder chooser dialog, and selecting the root of the external SD Card. Unfortunately the external SD card is never an option. The upper right 3 dot menu only has the option "Show internal storage" and does not have "Show SD Card" and the upper left 3 bar "Open From" menu only has "Recent" and "Downloads."

I've also set up a FTP connection to my phone but get permission errors when trying to delete or write files to the external SD card (I can read from it just fine).

The camera and other native apps allow using the external card as the storage location and the "My Files" file manager has full access. I am not rooted.

Any ideas?

问:
Which user data are apps able to collect by default?
On Android, I used to prefer the mobile website of services instead of their app because of possible privacy concerns. Now I'm wondering if this is actually unnecessary.

Android Missed Call Notification Sound/Chime
Consider this scenario. I am listening to music on my android phone and I have DND mode on and set to priority only.

Running commands operating on files always results in permission denied errors
When I try executing commands operating on files, they always fail. I can't check permissions on the terminal because I'd have to run a command that operates on a file (directory) in order to do so. Here is an example of what I mean:

Note that the terminal already shows a "Permission denied" error message when I open it.

According to my file browser, the /sdcard symlink (I suppose it's a symlink) has all permissions set. However, on the path to the linked locations, not all permissions are set. To test whether this is what's causing the problem, I created a new directory /t with all permissions set. You can see the result of me running ls in that directory in the terminal output above.

What do I have to do in order to be able to run commands that operate on files?

My phone is a rooted OnePlus 3 running OxygenOS 5.0.1 which is based on Android 8.0.0. BusyBox is installed.

Sony XPeria T service menu app missing
I just found out that I have a Sony XPeria T, not a Sony XPeria Z1 Compact. After years of owning it. Wow.

So I wanted to try some things that I previously discarded because they weren't possible with the Z1 Compact. One of those things is unlocking the bootloader.

So I went to the official Sony page for that and entered the code they gave me: *#*#7378423#*#*

The result of that: It disappears from the phone app as soon as I enter the last *. The service menu does not open. So I look in my apps list: No service menu. Apps like "Service menu for XPeria" also can't open it.

I also can't find a working apk for it online.

How to have a dark / black Quick Settings (swipe down) menu on Oreo 8.1?
I always used to have a dark or black Quick Settings (the swipe down menu) but since Android , it's white. And I can't find out how to change it. Invert Colors is not an option, as that messes up all colors on my phone whereas I only want to change the Quick Settings.

When searching on this problem I did find several apps (some of which even require root) to change the theme, but I can't imagine something so trivial really requires a custom app or even root.

Using Oreo 8.1 stock Android with all latest updates, no root.

Upon further searching, I found a partial solution: apparently if you set a "dark" wallpaper for your Home screen, it will automatically show the Quick Settings menu in dark instead of white.

Beats me why this can't just be customised manually, but for your reference: for example with the wallpaper below, I get a dark Quick Settings menu on Oreo 8.1 instead of white.

No clue what the criteria may be for a wallpaper to be "dark enough".
If there is a definitive solution I'd still love to find out!

Notify me only once or twice a day
Is there a way to bundle all my android notifications and let notifications arrive at a specific time of the day? For example, let's say I only want to check notifications at 10am and 6pm, everyday. All notifications after 10am until 6pm are put on halt, and at 6pm, I get a single prompt to view all the notifications from various apps.

My phone runs on Android 6, with MIUI 9 on top of it and I know for sure that this is not supported. Is there any android version or device in which such a feature is supported?

Serveral phones with same AppStore/Google login
I a have a large cluster of phones, about 100, in several places in the world. They are wall mounted, and I cannot access them physically, they all must be in silence (so are configured to reject calls, and be in silence). I have remote team viewer installed and setup to remotely access them.

All of those devices are logged in, as the same user in Android/PlayStore.

What I see, is that once in a while, the user gets logged out. I am unsure why the user gets logged out. This is first issue.

Second issue, is that when I do login, all other phones will get prompted to accept the login. This makes noise, and the phones should be in complete silence. How can I prevent the "Is this you?" popup to be displayed on all devices? (lets say I do have a few backups for me to accept it).

EDIT:

As suggested:
I viewed:
https://myaccount.google.com/security-checkup/1 (79 devices - ok)
https://myaccount.google.com/device-activity - all devices seen
In my shared GMail account - I don't see anything.

I am open for more ideas.

Libreswan (IPSec/XAuth) and Always-on VPN
I set up an IPSec/Xauth (RSA) server with LibreSwan on a server. My Android device (a Pixel 2 XL with Android 8.1) actually connects fine when I manually start the VPN connection, and it does tunnel me through the server.

However, when I configure it to be "Always-on" it doesn't seem to work. To be precise:

IKE and SA establishment succeeds

Android reaches to connectivitycheck.gstatic.com and appears to succeed

I see occasional NAT-keepalive packets

But (most importantly!) no ESP packets are ever sent by my Android device!

Has anyone encountered this issue before? Even details on how the behaviour of Always-on VPNs differ from regular ones would be very helpful.

I did see this question here, asked back in 2014: Always-on VPN sends no traffic

Unfortunately for me, his problem went away when he updated to lollipop.


问:
Make Google voice / assistant listen always when ear buds connected?
My bluetooth earbuds on my Android S7 phone do not have a button to activate Google Voice Assistant for things like note to self Etc. If the phone screen is on Google Voice is always listening. </p>

<p>How can I set Google Voice Assistant to always be listening when I have these bluetooth earbuds in?
Or how would I have it always be listening anytime wired earbuds are connected? </p>


问:
Home button, recent button, notifications, pull down menu all stopped working
I have a Nexus 9 running Android 7.1.1, and the home button, recent button, all notifications, and the top pull-down menu all stopped working.

The home and recent buttons respond to being tapped in that the animation that indicates I tapped them runs (the gray circle expands out from the button), but nothing happens. I can open the top pull-down menu, but it always says that there are no notifications, and I can't pull the menu down further to expand the icons.

I have about 15 GB out of about 30 GB available, and memory usage is listed at 1.6 GB out of 1.8 GB. I've tried restarting the device multiple times.

If I remember correctly, I accidentally drained the battery before this happened, but I can't recall if the device was simply powered off. When I powered up the device, the PIN prompt buttons caused the device to vibrate, even though I had had previously had that setting turned off. I restarted the device, and that setting turned back off. Double-tapping to wake up the device doesn't work consistently.

Any ideas?
