Strange Saving Behaviour of Samsung's "Write on PDF"
I did some work yesterday using Write on PDF on my Samsung S6 Lite tablet. Come this morning, and it didn't save. Bit of a nightmare. Anyway, I redid the work, but decided this afternoon to test out exactly how the saving works. It behaves very strangely!

I have uploaded a video (screen capture) to YouTube showing exactly the behaviour: https://youtu.be/ksfVwWm6iUY.

Basically, when I open with Write on PDF, it doesn't seem to save successfully. Instead, I need download it, open it up and write on it before saving. Even then, it saves some random stuff. The video hopefully makes this clear.

I want to open a PDF from a webpage (or app) in Write on PDF, do some writing on it, then save.
How do I get this to actually save?

问:
How exactly does NITZ work?
My understanding is that phones have an internal RTC (real-time clock) which is regularly synchronized, using NITZ (default) and NTP when the phone is connected to internet.

Carriers can broadcast a special signal encoding UTC time information (Year, Month, Day, Hour, Minute, Second, Timezone and DST) with an accuracy in the order of minutes.

I read the 3GPP specification and found when time information can be transferred from the serving PLMN to the Mobile Station (MS) / User equipment (UE) :

Upon registering on the network.

When the MS geographically relocates to a different Local Time Zone.

When the network changes its Local Time Zone, e.g. between summer and winter time.

When the network changes its identity.

At any time during a signalling connection with mobile station.

Automatic date and time needs to be enabled in the phone settings to either use NITZ or NTP. Technically a SIM card is not required right? If so, this should work in airplane mode but I didn't manage to trigger a time update after having manually changed the time.

I think I don't understand how it works in practice.

When does this trigger ? How does the cell tower know 2) 3)?

If it periodically broadcasts time information to every phones in the area then what's the meaning of these 5 points?

What does 1) 4) and 5) mean in concrete terms?

Regarding NTP, it is a lot simpler. Android will synchronize with a NTP server if there hasn't been any NITZ update from the carrier ever since 24H. The default NTP server is time.android.com (Google server) but I guess manufacturers may change this to use their own. (source: config.xml)

Persist changes to /system partition on A/B device (Android 9)
I’m trying to add the F-Droid Privileged Extension using the OTA .zip to a Fairphone 3 on which I’ve installed /e/ OS. I tried modifying the update-binary script because the mount points assumed in the script don’t quite seem to work on this device, but although the files seem to be copied fine to the system partition(s) in recovery mode, when I reboot the phone, all the changes have disappeared.

Stuck in Fastboot after deleting almost all the content in my phone (Xiaomi Mi 9T)
So I was trying to install Lineage OS (the unofficial version), because I think it works better with my phone. I already did that before, and I am not a newbie... But what I did today shows the contrary.

I downloaded everything on my PC and did a backup, and then I factory resetted my phone. After that, I activated the developer options and then the USB debugging and then I went straight into TWRP (I already flashed, I had a working, unlocked, MIUI ROM) and formatted almost everything (System, Data, Vender, etc, but not the USB option). I did something similar last time without any problems, so I thought this would be like the last time. But it wasn't.

After I did that, it sent me into Fastboot mode (kind of expected that), but when I tried entering some commands into the ADB console (like fastboot devices, or adb devices) it did nothing. The thing is, I tested it on my PC, and those commands were supposed to be working. I had the drivers and everything. I also tried to just flash back into the MIUI ROM (with the MIUI Flash tool), and it did nothing (it found my phone when I replugged it into my PC, but only for 3 seconds. Tried flashing and it didn't work). Also, I can't go into Recovery mode, it just sends me back into Fastboot mode.

I believe it's because of USB debugging not remembering my PC, even though I selected it to remember the PC. Also, I think the OEM is still unlocked, it has no reason to be locked as I did not enter any of those commands, I just... deleted my phone...

Any help?

Forgot Authy password
I accidentally broke my OnePlus 5 which contained the recovery codes for my Instagram and Facebook, both were using Authy as their two factor authenticator. Thing is I apparently don't remember my Authy backup password either, I've tried all my common passwords.

I logged into Authy on an old phone (Moto G5 Plus), I've tried all my common passwords, none of them seem to work.

There's no other way I can login to my Instagram. For Facebook they're asking for a government ID which I'm not comfortable providing. Authy is the only thing preventing me from accessing my Instagram and Facebook.

Is there any way I can brute force the password out of Authy on my phone? There's no desktop version or Firefox extension/add-on that I can use to login to unfortunately. Or is there any other method that I'm missing?

Any small help would be deeply appreciated. Thank you

I already run termux-setup-storage and restarted. As this should not influence the issue it did not change anything as well.

How to install the play store applications not available in my country
I am a student reviewing multiple COVID tracing applications deployed in various countries around the world. Although I'm located in the US, I'm also interested in applications that other countries have deployed.

As far as I understand, to do that I would need to find a VPN server in the country I am interested in and browse Play Store from there. It looks that people all around the internet advise to:

Connect to the VPN,

Remove cache and data from Play Store, and

Restart Play store.

However, this does not work for me. Play Store still lists only the applications available in the US and prices in US dollars.

I have checked whether my VPN works and it does. whatismyipaddress.com shows that at least my search queries coming from the browser go through a foreign VPN server.

问:
Cannot create, move or delete files or folders on android phone's SD card even after write only attribute is removed
When my old 16 Gb microSD card I used in my LGE V10 (h900) running Android 6 failed, I bought a new card; opting for a Sansdisk 64Gb microSD card. But since I inserted the card, I have not been able to write, edit or delete anything on card using my phone. I can do so readily by plugging my phone into my Win10 computer through USB, but when I try to access the card with any apps whatsoever except the built-in file manager app, and try to do any sort of write-related functions on it, they always fail.

Most commonly, I've tried to create folders on the SD card, but every time, I get the message "Folder failed to be created".

I first noticed the problem when I tried to set the SD card as the backup save location for SUPER BACKUP. Trying to select the root of the SD card, or any other folder that was added by formatting the card similarly fails, and even adding an extra folder using the built-in file manager didn't allow me to set that as the save folder for SUPER BACKUP.

So, I tried accessing it using ES FILE EXPLORER. It could read the card, but I could not move any files or folders onto it using ES, nor could I create any files or folders on it, or delete existing files or folders on it.

As per advice online, I downloaded the FX File Explorer App, and it recognized that my SD card was write only, and I used FX own auto-function to grant Write access to it, and the process seemed to run properly, and it recognizes my SD card as -RW, but whenever I try to move, create or delete anything on the SD card, I get the "folder was not created" error (or whatever I was trying to do).

I tried using FX to remove the write permission, then restarted the phone, and had it give write access to the SD card anew, and again, the process seemed to work without problems, but I still could not write to the SD Card using FX or ES.

I tried Unmounting the card, turning off the phone, extracting the card, cleaning the terminals with an erased and cleaned out the slot on my phone with canned air. Still couldn't write to the SD card.

I tried using the Storage Settings function to reformat the card. Still nothing. Again, I tried unmounting it, and reinserting it, but I still couldn't write to it.

Now, for some screwy reason, WIN10 won't assign the V10 a drive letter when I plug it in to the computer, so I couldn't use any fix that required targeting a drive or volume, so I ordered USB 3.0 SD Card reader, and plugged the card directly into the computer. There, I tried several so-called "fixes" I found online

I used an elevated Command Prompt to use DISKPART to remove the WriteOnly attribute from the card (which is seemed to do), but upon plugging it into my phone, it still wouldn't let me create folders or files, move files or folders onto it or delete files or folders from it, giving me the same "failed" error.

I used Diskpart to again try removing the WriteOnly attribute from it, targeting it both by first Disk number, and then by Volume number, then cleared the card, created a new partition and formatted it from DISKPART. That, as some might suspect, ran me into the problem with cards over 32Gb not being able to be formatted with FAT32 by DISKPART. I downloaded the GUI version of the Fat32Format utility, and after removing write only and clearing it card, I used it to format the card and return it to my phone. Still couldn't write to it.

I used DISKPART again to try formatting it as NTFS, but my phone read that as corrupt, so I formatted it on the phone, making it exFAT, but still no access, even after using FX Write Access granting function on it again.

I tried using the Write Protect removal function of EASEUS TOOLS M BETA. At first, it read it as not having any write protection, but I ran the tool, and it apparently put write protection onto it. I then used the tool again to remove the write protection. Still no write access from my phone.

The card is brand new; it's from a reputable mainstream card company (Sansdisk), bought from Amazon.ca (not one of their subcontractor companies).

I've tried writing to the SD card with other file managers, including "FileExplorer", ASTRO and even Sandisk Memory Zone, but I simply cannot write to it.

Every other solution I've come across requires root, and it is impossible to root a LGE V10 from AT&T. They've locked the boot loader for some stupid reason, and the only TOT file I've found to use LGUP to root it with only has Android 5 on it, and the damned phone won't let me upload a TOT file that downgrades Android from 6 to 5.

I don't live in the US, so I can't access AT&T servers to try to get an upgrade to my version of Android. Needless to say, I'm never going to buy a phone that AT&T provides ever again, but unfortunately, buying a new equivalent phone is not something I can afford, and the phone is still working great otherwise.

The only other thing that I can think of that might possibly have a remote chance of causing it was the fact that I recently changed mobile providers, requiring me to change my SIM card from a KOODO one to a PUBLIC MOBILE one, but I'm not sure how that could have messed up accessing the SD card; they're separate sockets, despite the fact that they're situated next to each other in the battery compartment.

Can anyone help with this? It's frustrating beyond all belief.

Need advice on deleting ".tmp" file in DCIM/Camera
The DiskUsage app shows that I have a 1/2 GiB file under DCIM/Camera, called something like 20160701_173401.tmp

DiskUsage will run HexEdit and show me the file...so I can see it's an mp4 video file, but since the filename suffix is ".tmp", it won't play it for me.

I'd like to get rid of the file ...
Unfortunately, DiskUsage also won't remove the file :(

The Camera app, and other apps aware of videos/images, can not "see" the file (or, said more precisely, it probably ignores it due to the ".tmp" suffix).  (I've also tried several "file explorer" type apps...no luck.)

The phone (Samsung Galaxy S7 Edge) is not rooted.

Is there a way to delete this file, short of resetting the entire phone?

I haven't tried yet, but am willing to write a special-purpose Solar2d (Corona SDK) app to "open" and "remove", but I'm not sure that's going to work.
...nope.  Did that, fails for "no permission".

After screen overscan resize, some apps double the resize
The top section of my Samsung screen is completely non-responsive.

So I followed the excellent guide here to change the overscan.

I did adb shell wm overscan 0,245,0,0, followed by  adb shell wm density 230 to normalize the display and not have words cut off.

It seemingly worked great, I can now access my notifications with swipe down, can interact with the controls that are almost always at the top of apps...

However, I'm wondering if there's some additional setting I need to change, because some of my apps are now adding a bunch of additional dead space and there's a lot of weirdness going on.

So for example, play store and instagram both add a bunch of additional "dead" space in the area that is actually alive, and they aren't even consistent between the two of them about how much they add.

There's a lot of weird behavior going on around this. Nova launcher thinks 200 px of the active area don't exist, and therefore will not let me place widgets there, even though I can clearly move the widget with my finger and have it show up in the area. Maps displays the map up to an area that is one overscan displaced from the actual overscan, but then places the top bar an additional overscan down, which is just weird.

Not every app has this. Here's chrome, working normally, with just the overscan I set:

Edit: I see there's a similar question
How to stop apps from doubling overscan?. However, it has no answers, and the suggestion in the comments to clear cache partition and app cache does not help.

I tried reverting back playstore to factory version, now I can't even enter playstore. It just keeps loading forever. I am unable to uninstall play services as well, neither can I delete the data. Yes I did try to deactivate the "find my device' option, but upon tapping "deactivate", the whole option gets greyed out and nothing happens.

I'm not being able to do anything on my phone, and its driving me crazy. Any sort of help would be highly appreciated :)


问:
Recovering from a boot loop (Samsung S9 Plus) ... which CSC?
I am currently stuck in a boot loop with my Samsung S9 Plus. The phone in question can be booted into recovery and download mode, but that's about it.

I found that I should be able to use Frija or SamFirm to download the latest update, but it prompts me for the CSC. Now I understand what the CSC is supposed to be, but how do I find the appropriate one?

In my case the phone was bought in Germany, but initially it showed stuff in Italian when turning it on. So which CSC should I use? Or does it actually not matter at all?

Would it be okay to go with DBT (Germany, unbranded) as per this list?

I didn't by the phone from the carrier, but on the free market.

NB: since the system is in a boot loop it's too late to look up the proper CSC.

Xiaomi Redmi 5 Whyred turns itself off
My Xiaomi Redmi 5 Whyred started shutting down randomly - rarely enough to make is hard to reproduce. So far happened once during a day and every 2nd night.

I am using a Havoc-OS 2.9 (Based on Android 9) and had no problems with the system until last week, made no major changes to the system, dont even think I installed anything new.

So far I have tried freeing up some space, because I was tight on that, made sure phone is charged and no night-only-features are on.

Shaking phone to see if battery is not connecting somewhere gave no results - also phone turns off when on a flat surface and not moved, so I do not think that is the issue.

Installed accubattery to see battery health but it did not provide estimate yet.

Below I have attached a screenshot of battery usage, as you can see it is not a case of sudden battery drain.

If someone provide me with some clues about what to look for I would be greatful.

问:
Skype integration with the native contacts?
I tried adding Skype information to my contacts and there's a gray circle showing up beside the Skype username. I can then deduce that it is indicating my contact as offline. However, there seems to be some inconsistencies. On some contacts, I can see three options below them namely:

IM with Skype

Call with Skype

Video call with Skype

However, on other contacts, there aren't any options below their Skype usernames. And also, another inconsistency is the status. My contacts would show up as online on the Skype app but will still show the gray circle on the Contacts app. This happens fairly most of the time which defeats the purpose of it having an indicator there in the first place. At times though, it would correctly and show a yellow circle on online contacts.

I want to know why it's behaving like this and if there's any way to make it less buggy than how it is right now.

Also, can't I just click on the Skype username on the Contacts app and have the Skype app open up their profile? It seems easier that way instead of adding the three Skype actions I stated earlier.

Why can my phone only play ringtones from my SD Card now?
I have a Samsung Galaxy S8 running Android 9 (at least currently - I don't know when that update took place, so I don't know if it is responsible for this issue). I have always had my ringtones (in mp3 format) in a folder on my internal storage, and my music (also mostly mp3) on my SD card. Sometime in the past year, an update caused my ringtones to stop working. They would not play at all, even when trying to preview them in the ringtone selector. Instead, the default ringtone would always play.

After some trial and error, I discovered that I could only get my ringtones to work if I put them on my external SD card.

Has anyone else seen this issue? Is there a way to fix it? It's very annoying, and messes up my file organization and management.

Hardware factory-reset for Philips TV (PFH5500)
I'm trying to boot a Philips TV (model 48PFH5500/88) into recovery mode. The television is stuck in the Philips logo splash screen and is essentially bricked. The front LED is pulsing every 1 sec, which I've read is an indication of an issue.

Tried the following:

Connecting to it via adb to boot into recovery - the device is not seen.

Hardware reboot by holding the joystick in the back on the "down" position when plugging in the TV and keeping it there for several minutes.

Unplugging for 1 to 10 minutes and re-connecting.

Entering support codes via the remote (per support manual) to enter service default mode (SDM) or factory mode.

All of these did not yield any response.

I'm looking for a hardware based reset/factory-reset method. Is there any trick I could try to force the device to start anew?

Mysterious vibrations from "System Interface"
For some time my Samsung Galaxy Note 9 vibrates for no apparent reason. It's a very short vibration with no notification of any kind so at first I thought I'm imagining things. But I noticed it's really there so I tried to find out which app is to be blamed - using Nice Catch I got a Vibration history for my phone (please excuse polish language on the screenshots):

Here comes the issue: these irregular vibrations come from Interf. sys. which I presume stands for System Interface. But as you can imagine googling "Android System Interface" wasn't very successful. Logo is just an Android Q logo so that doesn't help either.

I found this app among system applications, but it's Notifications settings are all locked (except for Screenshots and App icon notifications):

So now I'm kinda stuck and have no idea how to proceed. Any ideas on what I can do to disable those irritating vibrations?

Is there an obvious reason FireFox would freeze on my DroidX (2.2 Froyo)?
For some reason, when I run FireFox, it starts out pretty snappy, but very frequently (though not 100%) after 1-2 hours of very normal/light use (e.g. 1 tab with actively read Google Reader mobile page as well as opening [1/2 tabs at a time] 5-10 separate articles from said reader), the browser just freezes. Most of the time, the freeze is complete - e.g. it will sit there for 5+ mins (or forever), with no reaction to home or power keys, requiring a battery pull.

This happens at any time, from the phone being just after boot to phone haven't been rebooted for 3 days.

System: DroidX, with original stock Froyo 2.2 ROM, rooted. FF version is IMHO irrelevant - this is happening now with whatever the latest Google Play market version is (10? 11?) but also happened as far as 2 or 3 FF updates back as well, for at least 3-6 months. I didn't use FF for browsing before then so don't know if earlier versions behaved better.

I have virtually no add-ons installed, but can provide a list if this seems relevant (not sure how to launch in "safe" mode in Android sans addons alltogether).

P.S. Before someone asks, this is definitely not related to ATK - the symptoms persisted after turning off/freezing ATK, never mind the fact that FF is on ATK's whitelist.

Is there a usual known reason for this behavior? What are suggested approaches to troubleshoot?

P.S. The only other app which freezes the phone with any regularity is Google Maps.

How to use ODIN with more than a dozen of mbn, bin, img, ext4 files?
I'd like to flash my SM-T813 because it's in a boot loop. I downloaded supposedly the latest firmware. I think it was a tar.md5 file, I peek into this tar file and it's a whole bunch of files:

ODIN has these slots: BL, AP, CP, CSC, USERDATA. I possibly want to lash the bootloader as well. How do I continue from here, which file is which? I see what are the slots here What do the terms "BL", "AP", "CP", and "CSC" mean in Odin?, but not sure which files is which. I guess .mbn means some boot record (?). System.img is the largest, but the other img files are probably important too (actually probably most files).

Routing to Google Map services issue
I'm developing an Android application on a tablet that must use both Ethernet (trough USB adapter) and internal LTE carrier (or WiFi) to access Google Map services.
When I connect the USB/Ethernet adapter the application becomes unable to authenticate on Google Map services and therefore map is not populated at all, when USB is unplugged the application works correctly and Google Map component correctly shows its content up to the maximum level of detail.

May this depend on a routing issue? How can I fix this?

BTW the Ethernet port on this device is used only to access other devices located on a private LAN whose network is known.

PS The device is a Samsung Galaxy Tab S2 8.0 t719 running Android 7.0.

-- UPDATE --

I'm not certain of the missing authentication since USB port is busy and I cannot see app logcat dump in realtime but the behaviour is the same I can observe if Google Map authentication fails for some other reason (i.e. WiFi turned off while debugging, invalid Google Map API key etc).

I keep getting redirected to TWRP after trying to boot to my newly installed LineageOS-16
I've been trying to install LineageOS 17.1 on my Xiaomi redmi note 8 for almost a month now, and there is always one obstacle or another. First problem is that while the tutorial websites clearly state their version is made for the redmi note 8, The download page itself always states that the rom is made for the redmi note 8 PRO. In the zip name also  mentions unofficial, while other lineageOS downloads don't mention it. When I'm on the official website, I can't find my phone in the download page (Xiaomi Redmi note 8). When I succesfully installed the (unofficial) ROM, I tried to reboot my phone. Instead of entering LineageOS, it reboots into TWRP, even when I reboot it by pressing system under reboot in the twrp menu. Now, I tried to install LineageOS 16, but the exact same happens. I always wipe the dalvic cache and cache in between actions. I do have a nandroid backup from MIUI11 in case it just won't work out...
Thanks for being awesome!

I am using:

I've installed: Magisk 20.4

I've tried installing:
LineageOS 16 by DarkJoker ; LineageOS 16 ; LineageOS 17.1 UNOFFICIAL ; LineageOS 17.1 V2

Last time, I tried to flash vbmeta.img first, before flashing the ROM

In all cases, I can't reboot into the system anymore unless I use my restore point.

Why does GBoard have inconsistent "space to use autocorrect"?
My GBoard is having so many issues with how it autocorrects next work suggestions.

Generally if I hit space bar it automatically inserts the suggested word from the suggested word row above the keyboard.

But then for seemingly no reason it does not do it for some words.

For instance: brain.

If I type "brakn" ... And hit space... Hit inserts "brain", which is what I want!

But if I type "braim"... And hit space... It does NOT insert "brain" even though it is the suggested word... It just keeps braim and underlines it to show it is spelled incorrectly.

It's driving me insane.

I have cleared my cache and installed / uninstalled.

Why doesn't space bar ALWAYS insert the recommended word, it only happens some of the time.

How do I stop my SIM card from auto-locking while powered on?
I have a set a SIM PIN on the SIM card I use in my Moto E4 Android phone. To answer some anticipated questions in advance:

I know my PIN

I want the SIM to lock when the system powers down or reboots

I want to have to enter the PIN when the system first powers up

All of the above are working fine for me

What I do not want is for the SIM to lock itself while the phone is powered on. I don't know how long it takes, but it seems like if I do not use the phone for an hour, when I try to use it, the SIM is locked again and I have to enter the PIN to unlock it. I suspect this means I cannot receive incoming calls for some period of time because the SIM card is locked.

I know the phone is not rebooting because after I unlock the SIM, I can still unlock the phone with my fingerprint. When the phone reboots, I have to enter my passcode.

I do not know much about Android, this is my first Android phone and I just have it as a backup. Is this auto-lock a feature I need to disable? It seems to me like a bad idea given that I want to be able to keep receiving calls. What can I do to fix this?

Sony Xperia Z1 Compact D5503 (Android 5.1.1) extremely laggy typing
Sony Xperia Z1 Compact D5503 with Android 5.1.1 os.

I got this cheap phone ~a year and a half ago.
Works well overall, but there's one problem that I had since I bought it, the typing is very slow; it's extremely laggy, I press a key, it displays the visual animated keypress for a couple of seconds until it identifies the next keypress. Then 1 more second for another keypress. This is ridiculous. In fact I still use my iPod 2G for notes and whatnot I bought in 2009 and typing works perfectly; no lag at all.

This doesn't always happen but I cannot identify the prime cause. It mostly happens when I'm typing in notes, and sometimes on the web browser. Other times web browser might work fine, messages work fine. I tried installing 'Gboard the Google Keyboard' app, in case it'd help but no. Same thing.

I didn't mind much at first because I very rarely use it, occasionally for notes. But lately I've been using it more (you don't have much to do in the army other than get a smartphone with internet and browse the web, or read, to pass the time) and I am seriously at the brink of tossing it 100 f*in metres away. I do want to get a "dumb phone" asap actually if this is not resolved.

If you have anything to suggest that would be great.

NO, there is no spoofing software on it. It seems that this is normal reaction of hackers in china, they do not like constant MAC Addresses.

Android Encrypt with ADB install? TWRP CarbonROM
I have the following problem: I have CarbonROM 8.0 and the default /data full encryption does not work. Now I want to set it up with the ADB {Android-Bridge}... à la: adb shell recovery --set_filesystem_encryption=on

问:
Access App content [non-root] [non-debugable] [no-backup support]
Background:

I am using an app (developed by my network carrier); each month a bill is generated for my usage detail, it is a PDF file, which is only visible in app (no save, no export option). In app, there is a limitation of viewing only last three-month’s bill. I want to save generated bill to maintain history.

Scenario:

The OS of my device is android 9, non-rooted (and I do not want to root my device).

Analysis:

With some emulation, I figured-out that, app is saving these files (bills) in a (temporary) folder, which is located in /data/data/com.app.package/files/

I have also tried ADB commands e.g. run-as and adb backup but not achieve the task (application is not debugable and backup support is disabled on this app).

I also tried multi-droid app “Parallel Space” (as described in different tutorials e.g. How to View/Edit AppData on Android) but shockingly, app folder (among other apps) is not accessible (might be due to some security patches).

Question:

Is it possible to access / copy (protected) files generated by app in /data/data/com.app.package/files/?

Is there a quick way to change settings on Android?
Sometimes I need to quickly change a couple of settings, which are located deep enough (3 or more levels) in the settings menu. Is there a way to do this without actually opening the settings or writing my own app (which I could probably do, but why doing something that could be done more easily, right?) to do so?

I have thought about: maybe there is something like pinning certain settings to homescreen or something like .bat files on Windows? Or maybe there are certain apps where it is possible to quickly change settings from a list or even create some settings presets?


问:
Can I find the path of name resolution?
I'd like to know which name servers are asked for a name, when I try to connect to a local device by name. Is it possible? I have a local DNS, which mostly works fine, but sometimes not.

For example, I can ping web.home.myname (myname=an own TLD, not a real one), or I can access this site from Android browsers if I'm connected to my Wifi. But can't when I'm connected to LAN via my own VPN, although the OpenVpn server pushes DNS settings to clients.

I'd like to see what's happens when I'm using VPN, but every DNS tools are using Google's DNS, instead of local server. Even if I'm connected to my Wifi (when I can access lan devices by name).

I'm trying to explain by real examples.

I have an Asus router with stock firmware, which acts as router, Wifi AP, DHCP server, DNS forwarder, firewall, OpenVpn server and PPPOE client.
I have a server with many docker containers, including a container which runs dnsmasq. It is my main DNS, this is the only one, which can resolve the local domain names. I've configured DHCP on the router, to send the container's IP to clients as DNS server.

When my mobile connects to the AP, all apps run on this device, can access local devices by name. Because of it, I think, Android is able to use my own DNS server instead of Google's.

But... when I connect to the OpenVPN server (from the Internet), which runs on the router, I can access LAN devices by IP address, but not by name (with 3rd party firmware it works fine).

The VPN server has been configured to push the DNS settings to the clients but it doesn't work.

That's why I'd like to see, how are the names resolved, which DNS servers are asked when an app tries to access devices by name. The tried tools connect directly to 8.8.8.8, but the browsers and programs in termux app aren't, because they can access lan devices by name if the mobile is connected to the Wifi.

Ps: the mobile isn't rooted

问:
USB host port via Android accessory protocol adapter
Is it possible for an Android 4 phone with only a standard micro-USB port (not OTG), to be provided with a USB host port through an adapter using the Android accessory protocol? Do such adapters exist?

The adapter would need power and 2 USB ports. One USB port would act as a host and plug any USB device (for example a keyboard), the other would act as an 'Android accessory' and plug into the phone. Android should be able to use the device as if it were plugged in directly to a host port (on a tablet).

It would be really great if the adapter was also powered by micro-USB, and that it could pass-through data to a computer host (Storage, tether, ADB, etc.).

Is all/any of this possible? Do such adapters exist? If not, how would I make one?

问:
How to mount a tmpfs directory that would be allowed to be read and written to by any app? (root available)
I am trying to create some volatile (tmpfs) storage for my Android, to avoid clutter.

I am trying to follow the previous questions:

making manually mounted partition folders write accessible to all apps

and

How to bind mount a folder inside /sdcard with correct permissions?

The way I am doing is by adding an "init script" into a magisk "service.d" directory:

```<code># cat /sbin/.magisk/img/.core/service.d/001-tmpfs.sh

#!/system/bin/sh
while [ "$(getprop sys.boot_completed)" != 1 ];
do
  sleep 1
done

su -mm -c mount -v none -t tmpfs -o size=4g,nosuid,nodev,noexec,noatime,context=u:object_r:sdcardfs:s0,uid=0,gid=9997,mode=0777 /mnt/runtime/write/emulated/0/Download/tmpfs-cleared-on-reboot
</code>```

Seems plain and simple, only doesn't work in the sense that the folder is mounted successfully, and files disappear after a reboot, if copied there by root. But an ordinary app cannot copy anything there. FX Explorer, for example, says "Access was denied."

It does work though if I set setenforce 0, which seems to indicate that there is a SELinux problem.

The only relevant error in dmesg looks the following:

```<code>[ 3181.763111] [20200731_13:36:57.002188]@1 type=1400 audit(1596173815.897:12245): avc: denied { create } for pid=5870 comm="Thread-139" name=233339202D5370656E63657220477265656E62657267206F6E20696E7472696E7369632076732E20696E737472756D656E74616C2076616C7565732C206F766572636F6E666964656E63652C20616E6420686F7720746F2061637475616C6C79207570646174652062656C6965667320696D70726F76656420617564696F2E6D7033 scontext=u:r:untrusted_app:s0:c104,c256,c512,c768 tcontext=u:object_r:sdcardfs:s0 tclass=file permissive=0
</code>```

It appears if I try to copy some file into this directory.

ls -lahZ /mnt/runtime/write/emulated/0/Download/ gives

```<code>drwxrwxrwx   2 root everybody u:object_r:sdcardfs:s0   40 2020-07-31 13:25 tmpfs-cleared-on-reboot
</code>```

ls -larhtZ /storage/emulated/0/Download/

```<code>drwxrwxrwx   2 root everybody u:object_r:sdcardfs:s0   40 2020-07-31 13:25 tmpfs-cleared-on-reboot
</code>```

Which is strange, because the other files in the directory have permissions like this:

```<code>drwxrwx--x   2 root sdcard_rw u:object_r:sdcardfs:s0 4.0K 2020-07-30 20:04 pdfs-scientific_papers-toread
</code>```

the group is different. I am not sure whether this is related or not.

But anyway, I cannot copy anything into this directory as a normal app.

I can copy stuff there as root, and it disappears on reboot, as expected. But where is the permissions problem?

This is Android 9 on OnePlus 5t.


问:
Samsung galaxy s7 submerged in water. How serious can I expect it to be?
I dropped my Samsung galaxy s7 in water. It was submerged for less than 10 seconds, I turned it off within 30-60 seconds after that. It was working properly when I pulled it out of the water and while I was wiping it's surface dry, and I also managed to shut it down cleanly. I've wiped the audio jack opening and the USB port with a thin piece of tissue paper and also dried out any openings with a hair dryer. On hindsight probably shouldn't have done that, but it's already done. I've pulled out the sim card, and at least the sim card slot looked completely dry inside. It's since been turned off and is completely covered by dry rice.

How much damage am I looking at? This is the first time I have had water problems with a phone with an unremovable battery, and it doesn't look like I can do much else with it at home. Should I take it to a repair shop anyway and have it opened and dried? I don't know how much it would cost, and since it is an old phone anyway I don't know if it'll be worth it if they ask too much. Since the phone seems to be pretty water resistant I am wondering if I can just brush this off.

How much damage can I expect? If the phone turns on, charges and works normally is it safe to continue using it as usual? I am okay with keeping it under rice for 24 hours or more if that's necessary. When is the earliest I can turn it on again?

Sailfish (pixel 1) phone with stock android stuck in boot loop: help installing lineage
I have successfully installed lineage os on a nexus 6 that worked perfectly with stock android. That is the extent of my experience with non-stock android.

I have a google pixel (sailfish) device that a long time ago stopped working. I could boot into android, but the CPU seems to race, as it gets extremely hot, and then freezes and eventually reboots, shows a google splash screen for a few seconds, reboots again, and is stuck in a constant state of rebooting. I let it cool off, rebooted into android, quickly (I usually only have a minute or two before it overheats) enabled developer options, enabled oem unlocking, enabled usb debugging, and then rebooted into fastboot. The phone is stable in fastboot (does not get hot, does not freeze or reboot), which suggests to me that the problem I am having is not necessarily hardware.

In addition to serial numbers and memory amounts, the fastboot screen indicates the following:

Product/Variant: sailfish-US-PVT

Boot-slot: a

Console: DISABLED

Secure Boot: PRODUCTION

Device is UNLOCKED

I tried booting into twrp:

```<code>$ fastboot boot twrp-3.4.0-0-sailfish.img
downloading 'boot.img'...
OKAY [  1.190s]
booting...
OKAY [  0.956s]
finished. total time: 2.146s
$
</code>```

But the phone reboots into the google splash screen, and is stuck in the same infinite boot loop as before.

I have tried many different twrp versions, including twrp-3.2.3-1-sailfish.img which the maruos website suggests, all with the same result. I also admit that I have done various other things out of desperation, like erasing partitions and attempting fastboot format commands, most of which gave errors and did not complete. I also tried booting into recovery mode from fastboot screen, but that takes me to the same google spash/loop.

Can anyone help and provide suggestions for what to try next?

How to keep notification badge when dismissing notifications?
I am running LineageOS 17.1 (which is based on Android 10). When I receive e.g. an e-mail or a Telegram message, the notification appears as you would expect and the app icon on the home screen gets a notification badge with the number of unread messages.

When I swipe such a notification away, the badge disappears. I have found posts on the internet claiming any of the following:

This is intended behaviour, system-wide.

This depends on the launcher.

This depends on the individual apps and the best way to get the badge to stay is to write to the respective developers.

Question

How can I make the notification badge persist until I have actually read the message?

I'm hoping for some hidden setting, but I'm willing to install some magisk module or if it's easy enough to contribute some code for adding such a setting to lineageOS (though I'm unaware yet of both their guidelines and the complexity of adding such a setting).

Use Case

On my old phone with android 7.1.1, that was the default behaviour and it was highly convenient.

Example Case 1

A friend sends me 20 messages on Telegram. I see in the notification that they are not urgent and swipe the notification away because it is not currently relevant to me and should not clutter my notifications.
After work, when I have the time to reply in detail, I do so. Or rather, I would, if I hadn't forgotten about the messages because there is no indication that they still exist.

For this example case, Telegram explicitly has options under the heading "Badge Counter" called "Enabled", "Include Muted Chats" and "Count Unread Messages". This implies that the app itself would feature the badge independently of the presence of notifications (since muted chats don't generate notifications).

Example Case 2

I receive an invoice on gmail. It's something I'll get to later. I don't open the e-mail yet so that it stays unread, and swipe the notification away.

how to to restore apps without reinstalling them after ROM change
I installed a custom rom on my Android phone which is havoc  GSI 3.1   I am not happy with certain features that don't work and I would like to go back to the original ROM what is preventing me from doing that is the fear of losing my app data and building the phone from scratch. all my app APK files as well as the data be it internal or external is on the second partition of my memory card ( app2sd )  . now if I change the ROM and go back to OEM I do not want to go through the hassle of restoring all app data. titanium backup used to be good at doing it but now it's crappy and it does not do its job especially if there is a change in the architecture between phones or version changes in the OS. besides it will just hang whenever it cannot restore the app and you have to start all over again in batch mode. my understanding is that there is no registry equivalent in Android what we find in windows. so is there a method where I can recreate the links and point em to existing APK files on my second partition.  the other option would be in Nandroid backup of my internal data and then restore it to OEM.  which of these approaches should work..

I want to restore my contacts from a broken and black screen android device
I have a Samsung galaxy s5. Its screen has gotten smashed and now it displays nothing (black).

I can turn on the phone, and also I can enter recovery mode (by pressing home+power+volume up).

I have ADB installed on my laptop. But ADB can not access my phone and it shows it is unauthorized after typing adb devices, because it needs debugging mode to be enabled on the phone and I can not do that because the screen is smashed and black.

I have read that after entering recovery mode in your phone you can access it with ADB without USB debugging being enabled. So I entered recovery mode in my S5 then I connected it to my laptop, in my laptop I typed adb devices but nothing was shown. Does somebody know how to do it?

Is there any better solution?

How to backup files from a phone that's constantly freezing 20 seconds after turning it on
So I have a Huawei P Smart that's freezing 20 seconds after I open it and type its password for the first time. And after that, 2 minutes later, it's restarting.

I would like to save the photos and files from it before I factory reset it, but the computer simply doesn't have the time to save anything before the phone freezes. I have the time to enable USB debugging and data to access tho'.

I have tried opening it in safe mode, I googled and watched videos on youtube, but I couldn't retrieve anything.

Mute Google Meet's audio completely without muting the participants
In the Google Meet app, I want to watch the presentation of the meeting, but I don't want to hear anything. I can't just mute people because that will mute them for other participants.

I can't seem to find an output mute control or volume control in the app itself. I tried turning the volume all the way down on my Android device, but the volume slider won't go all the way to the bottom. Even if I set my device to silent, it doesn't seem to affect Google Meet.

How can I mute Google Meet's audio output completely? If it matters, the device is a Samsung Galaxy Tab A 10.1 (2016) (SM-T580).

(Root) Is there any way we can block internet accessfrom a specific app, not a whole system firewall or VPN that always run in the background?
Is there any way that can block also foreground internet access of a specific app permanently?
Not a VPN or similar that affects the whole connection and keep running the background.
No VPN!
Root is available.</p>

Broken recovery on Huawei Mate SE
So a while back I was trying to flash an unofficial TWRP recovery, and I ran into a bit of an issue. The process involved fastboot flashing a recovery partition that is unique to Huawei phones (something like recovery_ramdisk). Anyways, I essentially flashed an incomplete recovery that gets stuck in a boot loop whenever it tries to boot. To further complicate things, the phone will always try to boot to recovery after forcing it to power off. It always boots to this broken recovery regardless of other button combos or ADB commands (i.e. I can't get into download mode). The only way it boots to the system is when the battery drains to zero. It's as if a flag is reset when the phone drains to zero. It remembers to boot to recovery if I try to restart however.

My question is, is there a way to repair the recovery? Why does it forget to boot to recovery after it's battery expires, but then remembers after it powers on? Can I somehow get it into download mode? It's also running lineage 14 which I guess I flashed properly before TWRP.

Download all Reviews/App-Rattings from a App on Google PlayStore
I'm searching for a way to download all Ratings with Comments from an App on Google Play Store.
The best way would be to do this directly in python.

I have tried to download the whole website with the python package request. It works but load only about 140 - 160 Rattings with comments.
On the website, there is a way to click the button "see all comments". But then i must scroll to infinity. That is not the way I am searching for.

For clearness I want the data for a private NLP Projekt, so I don't have my own App.
Therfore all ways with the Developer Console not possbile for me.

The question is related to this one: See all Reviews/AppRatings on PlayStore in a better Way?
But the ways don't work anymore or I have no developer acces.

问:
Allow USB debugging for any PC without confirmation
My phone display slowly turned black for an unknown reason; Maybe moisture (SM-A320F Android8 - no root). I use scrcpy to show phone screen on my PC (and voice assistant when I don't have access to any PC). This software needs USB debugging.

I checked "Always allow USB debugging..." for my PC. However, each time I use Nox android emulator, computer RSA key changes and I should confirm it again. Once voice assistant stopped working in this situation and I luckily and hardly found Allow button in dialog by guess.

Is there any way to always allow USB debugging from any PC? I know it will cause security risks but if both scrcpy and voice assistant stop working again, maybe I can't find Allow button! I tried adb disable-verity but ADB says:

```<code>D:\scrcpy>adb disable-verity
disable-verity only works for userdebug builds
verity cannot be disabled/enabled - USER build
</code>```


问:
WhatsApp data directory is empty
I wanted to know where does WhatsApp store its profile pictures so I searched on google and found this article. The top answer of the above article said that WhatsApp stores its profile pictures in /data/data/com.whatsapp/cache/Profile Pictures directory. I used JRummy Root Explorer to view the above mentioned directory. When I went to /data/data/com.whatsapp directory, it was empty. There were no files or folders. So am I doing something wrong or WhatsApp stores those pictures somewhere else? If you know the answer, please write it. Thank you for reading.
