Google Assistant News are being emailed to me in the wrong language - how to fix?
I'm traveling and my Android phone's Google Assistant is now set to understand two languages, which is fine.

What's not fine: Google suddenly decided to email me all the info in the second language which is not English.

The emails are coming from the assistant-noreply@google.com address, so there's no way I can just reply and ask them...

I don't mind the emails, but I want them to be in English. Yet, they are coming exclusively in the second language. Drives me nuts. How do I fix this situation?

Disable Airdroid keyboard by default
My problem is that whenever I connect to my Android 7 phone via Airdroid Mirror on Windows 10 the Airdroid keyboard gets activated. Of course I can deactivate the keyboard by clicking the keyboard button on the function bar but this is annoying. I don't want to do this every time.

Does encrypting an Android phone also encrypt old, deleted files?

How do I set a custom SMS tone for a single contact in Android Messages running on Samsung Galaxy Note 8?
How do I set a custom SMS tone for a single contact? in the answer at https://android.stackexchange.com/a/16653/13886 it is claimed that this option exists in the dot-dot-dot menu, but it does not for my phone.

Was the feature there at some point, but then they took it out?

The phone is a Samsung Galaxy Note 8 running stock Android 8.0.0.

The Details button points to some central configuration that lacks adding a per-contact ring tone.

Is a specific app actually needed for this? Meaning, was this simply never built into Android? Or, is it there, but hidden by Samsung? Or  hopefully this is just user error, and I'm not finding the setting?

Adoptable Storage on LG Stylo2
I recently bought a 64GB SD card. Soon discovered adoptable storage is disabled on Stylo2, so I can't change app storage from Internal storage to SD card.
I followed instructions on another forum of how to enable adoptable storage on my phone using ADB commands.
It worked.
But now, my "Storage & USB" Settings shows both Internal Storage and SD card, but File Manager only shows Internal Storage.
And instead of having 16GB internal and 64GB external, File Manger is only showing 10GB TOTAL!!!
It seems like it was partitioned incorrectly.
Is there any way I can fix this?
I'm including a pic of some screenshots of the problem, and the code I used. I really hope you can help!

Correction: I've been exhausted, so I thought maybe I missed something. I looked back over the code from the other forum and over the code I entered. I missed line 3, so I  went back and entered the code, but the problem remains. The code is as follows:

sm set-force-adoptable true

sm partition disk:179,64 private

sm set-force-adoptable false

sm list-volumes all

Would be nice to partition 8GB or so to adopted storage, the ramaining 56GB of the 64GB SD card to "portable"/external storage.

I will probably see e-mail replies before I see them here..

location via WiFi, cell tower not working anymore
I have a Nokia 8 Sirocco with Android 9 (kernel version 4.4.153-perf+ #1). Since a few weeks ago I noticed that the phone seems to be unable to get its non-GPS based location - e.g. via WiFi locations or cell tower triangulation.

The symptoms are:

Google Location history is less accurate.

My shared location only updates for the other persons whenever an app uses GPs (and there is a GPS signal).

I keep seeing an "Updating your shared location" notification.

Apps that rely on location services take longer to boot up or be responsive.

Apps that rely on location services do not work at all without an available GPS signal.

Location based Smart unlock is not working.

Location based reminders are not working.

I have checked the following settings under Security & Location » Privacy » Location:

Under Google Location Accuracy the Improve Location Accuracy is On.

Under App-level permissions all relevant apps have permission to access the device's location.

Under Scanning both Wi-Fi scanning and Bluetooth scanning are On.

Is there anything more I could do to get this working properly again?

VPN not working in kitkat 4.4.4
I am using Lenovo A6000 running stock rooted Kitkat 4.4.4. And since about 6 months the vpn has stopped working properly. Everytime I connect to a VPN via mobile data, it connects and then gets disconnected after about 10 seconds and the 3G/4G icon vanishes too momentarily.As a result the VPN disconnects, rendering it useless.

I tried everything, different VPN apps, factory reset, wiped system, data, cache, dalvik cache, internal storage. Nothing fixed the problem.

This problem does not exist in 5.0+ android but i really don't want to update because anything other than stock Kitkat is buggy and drains battery heavily.

Anyone know how to fix this?

Seemingly dead Sony Z5 Compact gets detected as QHSUSB Bulk
My 2 year old Z5c (E5823, non rooted, official Sony Nougat update) died while updating some app, and doesn’t show any signs of life since then. Connecting the charger doesn’t turn on LED indicator, but it does consume about 0.90A. I have tried all different reset procedures, and only the first time I tried the 2-minute reset did it vibrate once or twice. Since then it doesn’t ever vibrate either.

If I don’t press the power button before connecting to Linux, then it gets detected as QHSUSB__BULK (Manufacturer: Qualcomm CDMA Technologies MSM) only. However, if I reconnect it , then it gives a USB error related to "USB power limit exceeded” :

device descriptor read/64, error -110

I need to then either disconnect the batter or press the off button next to Sim. My first priority is to recover its data (the phone was encrypted however). And if possible, fix it. I couldn't find its schematics to confirm if it's a hardware issue or bootloader (hard bricked), and would greatly appreciate any tips or advice to further diagnose or fix it.

LG Spectrum Jumping To Home Screen
I've got a problem with my LG Spectrum.  I've had it about 3 or 4 weeks now.  It keeps jumping to the home screen.  In other words, whatever app I'm looking at or have open, it will just exit to the home screen.  It's an intermittent problem.  It doesn't happen all the time, but when it does it will often happen several times over and over again.  It exits, I go back into the app.  It exits again a second later.  I go back into the app, etc.

I haven't been able to find any particular pattern to it.  It can happen in any application.  It can happen while I'm typing, swiping or just looking at something.  It can happen if the phone has been on for hours, or if the phone was just barely turned on and I'm in my first application.  It never shows my any error whatsoever.  However, about 25% of the time I will see for a brief flash the Car Mode screen popup or the Car Mode icon appear on the status bar at the top.  So, I'm guessing it has something to do with the Car Mode being activated inadvertantly/incorrectly, but I'm not even sure how the phone decides it's time to start Car Mode yet.  Every other phone I've ever had you started Car Mode manually.

The phone is not rooted and the latest OTA updates have been applied.

How to force Android 2.3 to believe that there is networking?
(unsatisfied by answers in "Let Android believe it is connected to internet", they more about "how to set up networking")

The android device is connected to the Internet though my laptop over Wi-Fi in ad-hoc mode, not from any Android interface, configured from console (Android thinks that it is offline: both wifi and data transfer indicators are off).

Rotate status bar icons like in the navigation bar when in landscape mode
I want to do this to keep the status bar icons in the notch region when in landscape mode. I can see that showing time would be problematic but every other icon could just be rotated in place.

I wouldn't mind if the time was also rotated in place, e.g. For 10:23 you have

```<code>1
0
··
2
3
</code>```

It would free up more vertical screen space which is already scarce in landscape mode. Moreover, if your device has a notch then it's a much better use of the screen space than just blacking it out.

I was wondering if it's possible to do it in the user land at all or if only the OS can take these decisions and we'd have to wait for long for such a feature to appear, if it does at all. If it's upto the OS then where are such feature requests entertained?

Some apps automatically uninstalled after android phone restart
After restarting my phone I noticed that some apps are totally uninstalled, first I thought that they're still being loaded because they are installed on the external SD card but when I searched for them in the Settings\Manage Apps I couldn't find no trace of them. Uninstalled apps include ES File Explorer/Manager PRO and a few dictionary apps. One weird thing I found out is not only the ES File Explorer is uninstalled but all the files encrypted with it are moved to .android_secure folder on the SD card!

Also a few couple of megabytes has been freed on the SD card. I should note that after suspecting virus infections, I've already installed Bitdefender free antivirus and done a full scan which revealed two adwares and a riskware app that has been installed on this phone for a long time so I don't think that they are the culprit.

BTW, not all the apps on the SD card have been uninstalled.

Your clock is ahead

A private connection to *example.com** can't be established because your device's date and time ([current date and time]) are incorrect.

NET::ERR_CERT_DATE_INVALID

To establish a secure connection, your clock needs to be set correctly. This is because the certificates that websites use to identify themselves are only valid for specific periods of time. Since your device's clock is incorrect, Chromium cannot verify these certificates.

How do I move app icons between pages of the all-apps list?
My phone has four pages in its all-apps list (as opposed to its two pages of home screens). I know how to copy app icons from the all-apps list to any home screen. I also know how to move app icons within a single all-apps list page. (And while searching for answers to this question, I found how to remove blank home pages.)

What I haven't found is how to move icons from one page of the all-app list to another. To illustrate (simplified):

```<code>Home Page 1                      Home Page 2
 G         Say "OK Google"       T-Mobile             Visual

Phone  Messages  Play  Camera    Phone  Messages  Play  Camera

All Apps 1            All Apps 2            All Apps 3
A1  B1  C1  D1  E1    F1  G1  H1  I1  J1    K1  L1  M1  N1  O1
A2  B2  C2  D2  E2    E2  G2  H2  I2  J2    K2  L2  M2  N2  O2
A3  B3  C3  E3  E3    F3  G3  H3  I3  J3    K3  L3  M3  N3  O3
A4  B4  C4  D4  E4    F4  G4  H4  I4  J4    K4  L4  M4  N4  O4
A5  B5  C5  D5  E5    F5  G5  H5            K4  L5
A6  B6
</code>```

If I want to copy app "H3" to the home screen, I just press and hold H3, and either wait until pop-up menu comes up with "Add to Home" as an option, or wait a moment longer so that the Home screen appears, and then movie it until I'm ready to drop it. That's easy.

If I want to move "N3" to the end of the All Apps 3 screen, I just long-push, drag the icon to the end of the screen, and release. It's there.

But, if I want to move "N3" to the end of All Apps 2, I don't know how to do it, and that's what I'm trying to find out.

Append a string before opening external URLs
I frequently read news articles shared on social media.

A lot of times, these articles are full of advertising and other irritating elements. I use a service that strips just the content and formats the article in a nice presentation.

I want to automate copying and pasting those links. Basically I want to be able to click on a link on apps and have an option that attaches service.com/ before that URL and then opens it.

What I currently do

Long click the link on the social (non-browser) app

Share using a clipboard copier

Open Chrome

Type service.com/ and paste the original URL.

What I want to achieve

Click on the link on a non-browser app

Open service.com/original-url.com/etc on a browser

Some ideas:

A really simple app that registers a web intent, simply appends http://service.com/ to the beginning of the URL, and opens it on the browser. Unfortunately, I know zero Android programming.

An app that allows you to register custom intents and add custom actions to it. Is there such a thing? I was able to find those which are close, but not the same thing.

extremely slow (transferring large files collections or huge files takes hours even on USB 3.1),

extremely unreliable (device can stop responding even after sending just a few files),

not working at all most of the time (device that stoped working may not "restart" and may not allow you to copy files even after dozens of unplug cable-plug it again  sequences).

(I can see above message after each and every file that I copy; I have to unplug and plug the USB cable again after copying each single file)

Questions:

Supporting, OT and philosophic one: What am I missing? Why we are forced into using this madness? Why nothing had been done for five years to resolve it?

Main and real one: Is there any other way? Any fast, reliable method of transferring files from Android-based device to Windows-based PC?

Described problem was tested on Windows 7 and Android 8.0, so not the newest ones, but still very widely used. And on the quite modern phone -- Motorola Moto Z2 Play -- but of course happnes on dozen other Android-based devices that I own and billions of Android-based devices other uses.

And, as stated in links given in first sentence, absolutely nothing had been done into resolving this problem for at least five past years. Is this some kind of sadistic way of understanding market and treating its customers, developed by Microsoft and Google or what?


问:
How can I backup everything on an android?
I have a redmi note 5. It has been asking for updates for a while, which I have been postponing. The reason is that my previous phone, a huawei, got locked into bootloop when I did update it, so I have been weary.

But since I'm starting to cave, I was wondering if there was a way to backup absolutely, utterly everything on the phone, to the point of being able to flash it if I have to, load the data again, and end up holding the exact same phone I did before all that.

How high is the risk of bricking a phone by installing LineageOS or /e/?
I am going to buy a phone soon and I would rather buy an Android than an iPhone. However, I do not want to run any Google software on the phone, and I am planning on installing one of the custom ROMs LineageOS or /e/ (which is based on LineageOS).

I've researched a lot and I can't find any solutions to this problem. A couple of months ago I traveled by plane, and when I arrived and turned off airplane mode (I have it always turned on) I had this r above the signal bars.

问:
By looking at an Android source code, determine packets sent out protocol
is there a way by looking at the android application source code, or manifest file, I can determine what is the network protocol support for that particular application? or is it more of whether the android version supports it. For example, is it possible to see if an application does not support TLS v1.2 etc?

As far as I know, from the android API, there is a practice where people use network_security_configuration where it contains a method cleartextTrafficPermitted=["true" | "false"]>. This restricts accidental usage of clear text traffic if traffic is tunneled through a proxy.

Another alternative is if the application implements the socket by himself by doing SSLSocketFactory.

My intent is to move towards analysis of the mobile application packets if they are encrypted. I understand wireshark or any packet capturing application can work; i am just exploring different possibilities.


问:
Install TWRP on encrypted device
I would like to install TWRP on an encrypted device to make a backup and maybe reinstall firmware. (Samsung SMT-530) The reason I wanna do this is because when restarting, I am able to enter password to decrypt but will get stuck in subsequent samsung logo screen forever, without giving me chance to unlock device. And after some googleing the solution seems to be installing twrp and update firmware. The source for this solution says clearly that doing so will wipe out the device, and recommends to backup first. And I thought, and this probably will sound silly, I could make a backup via TWRP.

When trying to go into recovery mode, and install TWRP from sd card gives the following errors. First screenshot is after going into recovery mode, second is error messages after trying to install twrp from sd card

Most probably this is a silly question, but could please anyone tell me whether it is possible to install TWRP recovery and make a complete backup without having to wipe out - Factory Reset my device ? USB debugging is off device is unrooted and have tried to find clear info via google without success.

问:
How to find out what slows down a freshly installed OS?
I have two Fairphone 2 devices here, one owned by me, one by my mother. She got hers in September 2017, I in January 2019. Mine has a few slightly upgraded pieces, like a better camera and battery, but is otherwise identical. I first installed Fairphone Open on mine and it ran smoothly. Then I installed it on my mother's phone, which was already slow with the old system.

When going through the initial setup, it was so slow that some screens stayed white for ~30 seconds and it didn't get any faster later.

So the usual performance troubleshooting steps like "stop background apps", "factory reset", etc. don't apply here. It's also not the operating system's fault, because I used the same on a nearly identical device. For that reason, I suspect a hardware problem, caused by higher than usual wear (she doesn't handle her devices too carefully). But how do I check that? Are there special tools that I can use to detect for example lower than usual battery voltage or check the CPU and RAM for faults or anything like that, which could help in narrowing down the cause or the performance issues?

By the way i want to kill it because eris is listening to a port before even the initial page of the phone shows up, so likely it is receiving and sending info to an unkown machine


问:
Samsung Galaxy s10e requires password every few days, is it possible to disable safely?
Galaxy s10e, protected by a very long password and fingerprints.

I specifically went for a very long password intending to only type it in after restarting the phone.

In fact, the phone requires entering the password every 2 ish days, which, I read, is a standard practice with Android.

However, in the security settings I was able to find "Other security settings - Strong protection" that reads:

Encrypt your phone using your secure lock type

After restarting, you'll need to unlock your phone using your pattern, PIN, or password to access features other than calls, messages, and alarms.

That setting is on, and I believe it is this one that requires the password every so often. And it would appear from its wording that if I disable it, the phone will be unencrypted.

Am I correct in that assumption? Will disabling that setting make the phone unencrypted? (I don't want that.)

Is there a way to disable asking for the password every so often with Galaxy s10 specifically (as opposed to stock Android) without compromising the device encryption?

At the moment it feels like this feature works to weaken the phone's protection, not strengthen it. By asking for a password every so often, it pushes me to go for simpler passwords that are easier to type in.

Sony Xperia X Rooting issue when the unlock bootloader flag is set to no
I am trying to unlock a Sony Xperia X that was locked to a Canadian carrier (Freedom). The previous owner sold me the phone unlocked (SIM) but he failed to unlock the bootloader.

I followed the instructions here and realized that the rooting status states that boot-locker unlock is set to no.

I also got the developer options enabled and made sure that the OEM unlocking is set to true and USB debugging set to true.

Next I ran adb devices and my device shows up.

However I ran fast-boot devices after starting the phone in bootloader mode (Volume Down + insert USB cable), it doesn't recognize any device.

I am wondering: is there any way I can get around Sony's restrictive Boot-loader unlock setting and get root on my phone? I desperately need to get rid of some bloatware.

Shutdown/Reboot Process Hangs Device
Is there any reason a programmatic or command-line shutdown (or reboot) process in Android 7.1 might randomly result in a hard freeze-up, requiring a long (~8 second) press of the power button to force the shutdown? It doesn't happen every time, but seems to randomly happen infrequently, but frequently enough to be a problem.

Background Info...

I'm developing a "kiosk" style tablet, which runs 24/7. It's rooted and I have full control over it. It also has a customization from the supplier to automatically turn on when power is connected.

To keep things fresh and responsive, I want to issue a nightly reboot command. The reboot command was originally just a call to /system/bin/reboot -p via my own app "watchdog" kind of service that always runs in the background. (Yes, I know the -p causes the tablet to turn-OFF, but then our custom auto-boot will turn it back on immediately, if power is connected, resulting in a reboot situation... doing a pure reboot without the -p causes more problems)

Anyway, I've since moved on to experiment with all of the following commands to cause a shutdown/reboot, and none really fix the problem.

/system/bin/setprop sys.powerctl shutdown

/system/bin/svc power shutdown

/system/bin/am start -a android.intent.action.ACTION_REQUEST_SHUTDOWN

/system/bin/busybox poweroff -f

/system/bin/busybox poweroff -d 10 -f

One more bit of info... I made an app to shutdown/reboot the device every five minutes. I've been running it on about a dozen devices, and have about 4 or 5 failures every 24 hours.

How to determine what if any charge will actually occur when sending to an SMS short code
I keep getting texts from a short SMS number asking me to fill out a survey, or reply "STOP" to stop getting these messages.  But when I reply "STOP", Android gives me the message:

```<code>this may cause charges on your mobile account
</code>```

I did a Google Search for this message and found one specific service which said this is just referring to whatever charge your provider assesses to send texts, so with unlimited texting there would be no extra charge.  But the number that is sending me this message is not the service the web site is referring to, and I want to make sure that I'm not charged some extra amount just to opt out.

Is there some place I can do a lookup on the number that is texting me to see if there will be a charge and if so how much?  I have replied to other short codes before without ever having got this message so I assume there must be something to this number that I might need to worry about.

No such thing as full factory reset, wipe cache, dalvik cache. There is also no "install" option.

问:
Installing downloaded APK after accidentally denying
I was trying to install a downloaded APK onto my Pixel 3.  During the initial install attempt I was presented with a screen that looked approximately like this one (without the added emphasis on the correct 'Install anyway' option):

I took one quick glance of this screen before concluding "big green button, that must be what I want here!".  Which was a substantial error, because the big, green button in fact denies the app install.  Oops.

And now what's happening is when I go back to the APK and try the install process again, I'm no longer prompted about whether or not I want to 'Install anyway'.  Instead it just goes straight to the "App not installed" screen.  The one with the gray triangle on it.

How do I get the device to forget that I denied installation to this APK, so that I can successfully install it?

ADB Access in TWRP recovery mode - samsung A3, Linux
I can access my Samsung A3 (a3xelte) in "normal" mode in Linux using adb.
Today I installed the TWRP 3.2.3-0 recovery mode and entered it. According to this DroidWiki article(the article is in German), I should be able to use adb commands in this mode as well. However, "adb devices" shows me nothing. Any ideas or is the information wrong for this phone?

Reason I am asking: After resetting the phone to factory settings, some valuable Memo-Notes seem to be deleted. I would like to copy an image of the partition to my computer (as described in this answer from StackOverflow), and then use testdisk to potentially still find the relevant deleted file. The phone is not rooted which seems to make things a lot more complicated...


问:
Need help in connecting my Samsung mobile
I use [TP-link Archer AC1200] as my primary router (according to my phone, I think my router’s IP address = 192.168.0.1) with SSID-1. Connected to it is the [TOTOLINK A2004NS] (whose LAN IP = 192.168.31.103) with SSID-2. It is followed by another router [TP-link WR1042ND IP] (IP address = 192.168.31.8 ******) with SSID-3.

I have three cell phones:

  (A) Redmi 6 plus

  (B) LG Stylus 3

  (C) Samsung A6-2018

Both (A) and (B) can access all those SSIDs, but (C) can access SSID-1 and SSID-2 only. It can detect the signal from SSID-3, but reports that there is no internet connection.

Below. The pictures on the right show that All three can be interneted via SSID-1. Those on the left show that Samsung alone canNOT be internet to SSID-3 while the other two can. [The meaning of those Chinese words shown on the Samsung means "internet option may not be available".]

Are there any other extra settings that I need to fix the Samsung phone?

Additional info:-

This incident happens when I have added the AC1200 as the new primary router. That is, before that I just had the A2004NS and the WR1042ND but all three mobiles worked well.

问:
SD card had bad sectors after chkdsk. Is that Logical or physical ?and path from here
This is about data corruption on android . The primary issue relates to bad blocks / clusters and it happens to be android platform. So this is a super user and NOT android enthusiast question. answers to this question will apply to ANY corrupt card whether PC or android. So its thoughtless to tag this is android

This is a Sandisk 128gb  ( leave this link  - its not an ad .Specific card indicates other paras like memory channels , write speed etc card I am using on an Android Nougat device.

This is the 2nd time the card had corruption issues. 1st one I bought got Write Locked . Present Replacement was provided

The card has a lot of bad clusters. 2 things got me to sniff this :

whatsApp directory ( which had a bind to whatsapp dir on internal ) : the image directory can no longer be written to

Phone randomly reboots and next time  exFat partition is not mounted ( I used app2sd and partitioned the card to ext4 10gb  to link my apps and rest if exfat )

ran a chkdksk on windows 7 and it would autoterminate on initial run & persisting on running gave me repeated message "# cluster moved for file " ( cant recollect exact verbiage ). It could Never complete it but aborted with the message . "corruption found in card "

questions :

How do I know if there is logical  or physical bad cluster. Any tool / test ?

 Here's something I did - that made me think logical. I removed the images directory ( which was  write locked and so as long as the binding was on , whatsapp images could not be downloaded. Once I  switched off folder mount tool that enforced this, it would work ) after moving the contents to dir2 and renamed dir2 to original dir. after del the original dir. Now for sometime  whatsapp binding would work and the same problem came again . So I tend to think but need confirmation.

I am thinking of salvaging the contents of exfat partition and then format partition and instead create 2 ext4 partitions ( or FF2S. Tell me which is better) . One is for less write apps. My photos etc here and other smaller one just for whatsapp and then copy back contents to relevant partitions.

If I do this. There is no  out of box support for ext4 partitions for android ( isn't ,pl confirm) ? how do I auto mount without 3rd party utils ( fstab ? )
How do I auto mount the extra ext4 - fstab ?
Will this help avoid the above problem ?

While I still have the corrupt block partition  is there ANY other tool that will run  till the end and identify all bad blocks so they can be  kept aside .I tried aparted for android which runs fsck ( exFat sub ) and the report came normal in < 1 min .

Boot Loop with old CyanogenMod: Unable to stat various files
My old One Plus One suddenly refuses to boot without any changes from my side. OS is CyanogenMod 11. The device is rooted and there is TWRP 2.8.0.1 installed on it and debugging is active. The symptoms are as follows:

Once turned on the 1+ logo is briefly displayed as usual

Then the CM logo which looks like a turning bolt is shown indefinitely

I can boot to TWRP recovery mode. However, before attempting a factory reset I would like to do a backup with TWRP. This goes well for /system but fails for the /data partition. There are error messages  Unable to stat 3 files.    /data/data/com.android.providers.settings,
/data/data/com.android.settings/databases/google_analytics_v2.db-journal
and /data/data/com.android.settings/files.

When I try to make a backup with adb, I get stuck at the stage where I am supposed to confirm the backup on the phone itself.

Is there any possibility to enforce the adb backup and skip the confirmation? Any other means of making a backup od App date prior to attempting factory reset? Are there any other forms of backup which I could use?

I am also thinking about pulling the entire /data/data directory to my computer via adb. Would this be a viable option for restoring data later?

Thanks for any help!


问:
Local offset of clock
I'm using the App ClockSync on a Android 7.0 device (Huawei P9 Plus) and on a Android 5.1 device (Huawei MediaPad M2) and I face two problems.

I'm synchronizing the time with ClockSync on my Huawei P9 Plus device. When I then restart the device, the clock has a local offset of around 76 seconds. Why is that? By the way the device is rooted (TWRP). This only happens when I restart the phone.

On my Huawei MediaPad M2 device the local offset of the clock (shown by ClockSync) increases over time. After one hour I have an offset of 1 second. How can I decrease this massive offset? Automatic time synchronization is no option because I'm recording sensor data and I don't want to have a sudden jump in the timestamps.

On the other hand on my Huawei P9 Plus device the offset is not monotonically increasing but just jumps around and is always lower than 1 second. Why is the local offset jumping around? I have disabled automatic time synchronization in ClockSync and also in the system settings.

问:
Android verified boot and custom ROMs
I'm trying to figure out how exactly works the Android Verified Boot process and its usage with custom ROMs. The documentation I found on it is unclear (or outdated) as there seems to be several ways to do it.

What I understood (please correct me if I'm wrong) is listed below.

Before flashing :

The bootloasder is initially locked, and has to be unlocked through the fastboot command (and a physical confirmation from the end user).

The user data are totally wiped in order to prevent unauthorized access through rooting process (e.g. if a device is theft and the thief tries to access private data).

The custom ROM public key is stored in the user-settable root of trust (alongside with the manufacturer's one) when the OS is flashed.

Boot process (after flashing) :

The systems is powered on (physical button)

The device embedded BIOS reads the public keys stored in the root of trust (manufacturer and user-settable) and verifies that the kernel image has not been tampered.

If the public key used to check kernel tampering is the user-stable one, then a 10 seconds warning is displayed in order to warn the end-user that the pub. key used to perform these checks is not the manufacturer's one.

Once the kernel integrity is confirmed, the initial ram image is loaded and the init process is called.

The dm-verity kernel module ensures that the boot process is not tampered through cryptographically signature checks, using a public key.

As I write these lines, several steps are still unclear to me :

Why are warnings displayed during boot if integrity checks pass ? I mean, even if the user-settable root of trust is used (instead of the manufacturer's one), integrity checks are still OK, don't they ?

Is the UNLOCKED state needed in order to set the user-settable root of trust, or is it needed to bypass Android Verified Boot ?

How is handled the "tamper evident" feature for the user-settable root of trust ? I mean : the user-settable root of trust should only be set by the end user (and not the manufacturer) but how can we be sure that It did not set one anyway ? Moreover, if the system is rooted, how can we be sure that the "new" OS has not reset the tamper evident flag ? Are one-time programmable memory used ?

What public key is used by the dm-verity kernel module in order to perform integrity checks ?

Thanks in advance !

Video freezes but audio plays on YouTube
For the past two days YouTube on my OnePlus 6 has been glitching. Everytime I click on a video I can hear the audio but the video doesn't play (it doesn't go black, it just freezes with the audio playing in the background). Also, the new update allows me to swipe right to see the next video, something which isn't there on my brother's phone even though he has the updated version of YouTube (as per Play Store).

I deleted cache and storage in settings and also restarted my phone. The app works fine but again goes back to glitching after a while. The glitch starts with the home screen and slowly stops the operation of all the other features on YouTube.

问:
Kodi plays a completely different file
tl;dr: After 2+ months of using my Kodi 18.1 started to get a complete wako, by playing different movie than description, image, scoring etc. says. For example, it plays "The Hunt for the Red October" when I select "Zootopia".

Tried everything (rebuilding library, removing and adding the source), all for nothing.

My SMB/FTP server structure:

Movies:

Animated

Drama

Political

...

I have added two sources to my Kodi 18.1:

"Animated" --> SMB/Movies/Animated,

"Movies" --> SMB/Movies.

So, in fact, all animated movies can be listed / accessible through both sources (if that matters).

Now, in Kodi I am selecting first source ("Animated") and browse to the end of list ("Zootopia"). I see everything perfectly: description, movie poster, ratings, year, actors everything is correct.

The only problem is that when I start playing it, "The Hunt for the Red October" plays.

This problem occurs for most of the database entries in the "Animated" source (but not for all). For example "Jason Bourne" places when "Shrek" is excepted etc.

"Animated" folder in SMB/FTP is accessible both through "Animated" and "Movies" source in Kodi, but not the otherwise. I.e., if you open up the "Animated" source in Kodi, no movies from i.e. "Drama", "Political", "Action" etc. folders in SMB/FTP are accessible AFAIK.

And yet, Kodi gets wako and plays movies from different source than use is actually browsing.

Filenames are "purified" manually by me and files are named matching patterns "English title (Year)" exactly. So there is no way Kodi can get confused:

it claims that it is going to play movie "Zootopia (2006)" in "Animated",

it actually plays file SMB/Political/The Hunt for the Red October (1992).mp4.

I have tried everything that came to my mind. I have cleared the database (but this seems to be only deleting references to non-existing files, it does not recreate / verify references to existing files). I have removed "Animated" source and added it again. I have used "Look for a new content"-like options. All for nothing.

I have noticed that after removing the source and adding it back, Kodi still keeps information on what was watch and upon which time watching of given movie stop, i.e. still offers to "restart" watching from given position. So, it clearly suggests that removing and adding the same source again does not clear any cache or stuff like this.

Any idea what I can do in this situation except for throwing Kodi to hell and start looking for some alternative player for my Android-TV home player?

Copy files from Linux to Android without any OS
I'm trying to install lineage 15.1 on my old Sony Xperia V LT25i, which has had a couple of other OS's since the original. When I started the process I could not access the internal memory at all, neither from the phone itself or from my laptop.

I downloaded the OS zip file and the Open Gapps zip I want and started to follow this tutorial. I managed to run the $ fastboot flash boot boot.img command using sudo but now I need to copy the zip files to the phone memory which no longer has a running OS.

I tried using the adb push command but I get an error saying that the device is unauthorized. Running adb devices confirms this:

```<code>List of devices attached
CB5A1MMV58  unauthorized
</code>```

I then tried to find a way to change it from unauthorized to recovery and found a
YouTube tutorial which is supposed to solve it, however when I put the phone in recovery mode and run the cd ~/.android && adb push adbkey.pub /data/misc/adb/adb_keys I get this:

```<code>adb: error: connect failed: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.

I tried running adb kill-server and then running the above command but I still get the same result. As I do not currently have a running OS on the phone I can not enable ADB directly on the phone.

Correct TWRP Build for Samsung J7 (SM-J727U)
I have a boot loop issue similar to this post, and would like to try to flash TWRP on to my device with Odin. The TWRP site has four variations of the J7. I'm pretty sure that based on this specs data I have an Exynos processor, which narrows it down to two TWRP options:

1. Samsung Galaxy J7 (2016 Exynos) (j7xelte) TWRP page

This one has a link to XDA that indicates it is only for various SM-J710xx models.

2. Samsung Galaxy J7 Exynos SM-J700 (j7elte) TWRP page

The changelog on that one references exynos7580 which doesn't match the processor number specified on that specs link I found for my phone.

Huge battery power consumption with one particular SIM card
I have a Vodafone SIM card in an Android phone. In that phone, there is a 2000 mAh battery. I had noticed that the battery was discharging very fast, about 2%/hour when idle!

At that time, no battery consuming apps were running and all other mobile radios were switched off.

The discharge rate should have been less than 1%/hour.

I thought that this might be a problem with the battery, but when I tested with another Vodafone SIM card, I saw that the discharge rate has again gone down to 1%/hour!

Can anybody say what is actually happening?

Additional information: Few days ago, accidentally, there had been a half-hole on the SIM card. So, is the problem due to this hole?

Accessing a USB device in phone in absence of compatible drivers / modules
My android device has an MTK6797 Soc(Xiaomi Redmi note 4x mtk version), and the company never released the kernel source, now I want to connect a USB device through OTG and control it from a chrooted Linux environment inside android, the problem is that the precompiled kernel that ships with the android device doesn't include the driver for the USB device, the kernel also has CONFIG_MODULES disabled so I can't compile the driver as a module and load it to the kernel, so now my only option is to run a completely emulated Linux VM(kernel and userspace) inside android and connect the USB device to the VM and load the required module from there(just like you would do on a PC with something like Virtual Box).

The problem is that I can't find an arm emulator that runs on android, I found Limbo PC emulator which is based on Qemu but it emulates X86 and not arm, running an X86 VM inside Limbo PC is very slow so I instead I want to run Arm VM hopefully that would provide a bit of performance push compared to emulating X86.

I can't seem to find any thing that can emulate Arm inside android, Qemu is an open source project so It's hard to imagine that no one ever though of running Qemu arm emulator inside Android.

Why restarting the phone fixes the problem of Google Keep of not syncing the notes?
That was the question only, because that happens to me a lot.
I work with keep in pc and android, and sometimes even if a have an Internet connection the notes are not syncing. And I wonder why this problem is fixed only by restarting the phone. Or better explained...<br>
Why the process of restarting the device fix the syncing error?, so what's happening internally in the phone that's fixing the problem
Is this an app related issue? </p>

Nexus 10 boots into fastboot, but not into anything else
I am stuck with what seams like a dead Nexus 10 or a stupid issue.

If the device is powered off -- And I hit vol+ vol- and pwr -- It boots into fastboot.  After that, no joy.  I get black screen if I attempt to start (No Google logo even).  I get black screen when I try recovery.  I simply cannot get past fastboot.

Things I have attempted:

Disconnect / Reconnect Battery

Erased Cache

Finally flash-all with Manta Image (successful)

Still after all that, it boots straight to black screen.  Something is royally screwed, or I am missing something glaring .. Suggestions?


问:
Cannot boot into homescreen after installed Android PIE
My phone model is Asus Zenfone Max Z010D. My power button and volume up button are not working. Is there anyway to boot to the homescreen?

Since I have installed Android pie (AEX custom rom), they have this EDL issue (cannot reboot to device/recovery). I accidently rebooted the device, and it went to EDL. Then I rebooted it by holding the volume down key with the phone connected to computer by usb, but it then went off automatically. Now it is only showing the offline charging, while connected to charger.

How to resolve this?

APN settings in A500 with dongle
I own an A500 without 3G and a ZTE LF627 USB dongle. I donwloaded the thor_3g_patch_v14.2 and flawlessly installed it. I also had to unlock my dongle (tested from computer, works...).

Now I connected it to my Iconia. It shows the blue roaming light, and seems to be ready for connection.

How do I set up APNs in Honeycomb 3.2? I found that a new settings menu "Tethering/portable hotspot" appeared after ROM patching, but I see no more menus for setting up APNs. From ConnectBot I can also see /dev/ppp

Can you help me with that? I can't even install those applications from the market that enable setting APNs because Google forbids me.

```<code>~ # rild

Honor play won't install apks and apps from unknown sources
can't find any specific info on the honor play and why I cant install apks and unknown sources apps. The menus seem to be a little different to general android advice and I feel I've got the right options checked but I'm confused as heck. For info it's an honor play, android version 9, don't want to root the device, trying to install older update on Google play services pre March 2017 so I can spoof location but no apks seem to work.

Whenever I try to install any 3rd party apps or apks I get this message or similar, I've checked the options and on honor play there's a list of programs such as browsers and apps where I can allow them to install programs and they all have permission. There isn't a general option that covers everything like on most other android mobiles.

问:
Micro sd card partition strategy for Android (context of wear leveling & data corruption)?
The primary issue relates to bad blocks / clusters and it happens to be android platform.

This is a Sandisk 128gb  (leave this link - it is not an ad). Some cards indicates other problems like memory channels, write speed etc. This card I am using on an Android Nougat device.

This is the 2nd time, that the card had corruption issues. The first one I bought got write locked. I've bought a replacement. This card has a lot of bad clusters. 2 things got me to sniff this:

whatsApp directory (which had a bind to whatsapp dir on internal): the image directory can no longer be written to.

The phone randomly reboots, and next time the exFat partition is not mounted any more (I used app2sd, and partitioned the card to ext4 10gb to link my apps. The rest if exfat).

I ran a chkdksk on windows 7, and it would autoterminate on initial run & persisting on running gave me repeated message "# cluster moved for file " ( cant recollect exact verbiage ). It could Never complete it but aborted with the message . "corruption found in card "

Question

Given this situation, is there any OS utility or 3rd party tool out there, that can complete the card run and mark the bad blocks so, that these bad blocks remain unavailable to write? Yes, I ran chkdsk with /r /x options, and that is when it puked with all these errors, and it didn't run untill end. I tried aparted for Android which runs fsck (exFat sub), and the report came normal in < 1 min which tell me it didnt invoke bad blocks routine.

From what I read due to 'wear leveling' the dynamics changes so bad sectors can't be marked permanently, and the only temporary solution would be to do a low level format. Question is - is that so , pl. confirm my understanding?

Question

If the above is correct, I wanted to think of ways I can reduce data corruption and have a handle on the above. What I am thinking is , after erasing the data - instead of exFat. I will create several Ext4 partitions.

An ext4 for app2sd hidden partition (as is the case presently)

another ext4  pat # 2 for mostly RO data

ext4  pat # 3 for mostly Moderate RW data (like camera photos)

ext4  pat # 4 for mostly high RW  ( like whatApp media)

Is this going to help make life better than before?

Question

How do I auto mount ext4 (default external storage for Android is exFat or Fat32)  and that too more than 1 partition ?
Question
What files equivalent to fstab files in android (this is nougat) do I add my custom mount command to?

Question

Any other solution that comes to mind?

How to turn off flashing notification LED on HTC Sensation XE?
Two problems:

Thanks in advance! I ask this because I often read ebook on my phone, it's annoying to have the light flash.


问:
Device boots old version after update TWRP
Out of the blue, my tablet (Samsung Galaxy Note 10.1 wifi) made a reboot and got stuck in the loading screen. So I tried to install a new ROM (sideload), but noticed that I can't because then the installer says

```<code>installing zip file '/sideload/package.zip' error executing updater
</code>```

Then I thought, well maybe I should update TWRP to a newer version. So I did, at least, I thought I did. This is the most annoying android hell I've ever been in. I updated TRWP from 2.8.6 to 3.2.3, but when I reboot directly into recovery mode, which I did manually because I unchecked reboot option in Odin, I found out that the stupid Device is still loading 2.8.6. Next, I tried the same update from within TRWP itself. The flash succeeded, Reboot into recovery again and.. nope. Still 2.8.6. What the hell?

So then I tried pushing a simple test file to the filesystem /sdcard and /tmp and a custom /dl directory using adb commands. Then I reboot, aaand gone are the files. It seems my whole device is stuck in a permanent state. I can't change anything.

I gave up now. I'm working on this hell for 3 days and there is absolutely no positive movement at all. Why does Odin say flash passed, TRWP flash succeeded  and when I reboot, I still get the old crap? How can I flash my device from here on? It seems I'm stuck with it now forever. It doesn't update.

Other things I noticed:

When I load into TWRP I can use ADB commands from my Win 10 PC.

When I load into Fastboot mode, I can not use Fastboot commands. The device is not seen when using fastboot devices command.

I can not see any file inside /data seems to be empty folder?

When reloading TWRP theme, /data/media/0.. seems to be inexistent.

I got the Samsung Android USB drivers installed on my windows 10 pc. Device manager shows ADB device when I boot into recovery. But no Fastboot device when I boot into fastboot.

What is going on here? How can I fix this?
