Android image copy break original file date and time
I have found that if I have a WhatsApp image that I want to copy into a different folder on my Android device, keeping the original in place, then the date and time changes for the image.

So if I go into the phones gallery the date and time of both the images show the time of when I have copied the file. Why does copying break the original image? And lose important data on when the images were originally taken.

If I delete the second copied image, so only the original is the there, then the date and time reverts back to the original date and time when viewed in the gallery. It looks like the gallery when displaying the file date and time.is looking at the wrong version of the file??

I have tested this on multiple devices now and the same happens. I copy the file by connecting to the computer.

Using the native copy to in the photo gallery works on devices pre android 10, but has the same affect on android 10.

When "might" reported spam be sent to my carrier, and when "might" this incur an additional cost?
From https://support.google.com/messages/answer/9061432?hl=en

Learn about spam reports

If you report spam, Google will get a copy of up to 10 of the
spammer's last messages so we can improve spam detection across Google
products. Your past replies to the spammer are not sent to Google.
Your name and phone number are not linked to the spammer’s messages.
The spammer won't see or know about your report.

Your spam report might create a separate “Spam reporting” conversation
that sends a copy of the spammer’s number and most recent SMS message
to your mobile carrier, which might have an additional cost.

A variant of this message appeared on my phone screen when I attempted to report a text message as spam.

Before going ahead with this, I have some questions.

When "might" these messages be sent to my mobile carrier?

Why can't Google tell me definitively whether or not this will happen?

Why don't I get to choose whether or not this happens?

When "might" this incur an additional cost?

Why doesn't Google know if it will?

I am not comfortable with the vague warnings that "stuff might happen" and that I "might be charged for it". These are not statements that inspire confidence; and without knowing under what circumstances they will take place, it is impossible to make an informed decision.

Disable/enable second DualSIM card command
I use the MarcoDroid app to change phone settings depending on events.

I want to turn on and off the second sim card depending on the event. I found a command option where I can type the command to enable/disable the second SIM card. I just don't know what the command will be for the Moto Z2 Play phone?

The settings are shown in the print screen. Can anyone tell me how to search for a command and its parameters?

EDIT:

I found a command that you can use to change whether the phone is to be multisim or singlesim.

For dual sim:

```<code>su -c setprop persist.radio.multisim.config dsds
</code>```

For single sim:

```<code>su -c setprop persist.radio.multisim.config none
</code>```

The problem is that when I run the command to turn off the second sim card from the console, in the settings there is no option to choose which sim card should be responsible for what, but the card itself remains turned on. Incoming calls do not show up, but the caller has a call tone.

Maybe someone has an idea what other parameter in the console is responsible for turning off the second sim card?

问:
Do unlocked phones get re-opened at the factory?
This question is so borderline, I hesitate to ask it but will anyways. I recently received a new phone from a reputable online retailer, but when I opened the box there appeared to be a fingerprint and another smudge already on the device (before I touched it). I called the retailer and the customer service rep suggested that unlocked phones may be re-opened at the factory to be unlocked... which seems strange, because I would have through they are already unlocked and would only need additional work on them to load carrier skins.

I know I'm unlikely to get a completely satisfactory answer, but was hoping to tell if it's normal to see smudges on a supposedly new phone from the factory - maybe someone has worked in one before. While I think it's unlikely they need to re-open and seal the box, I would have thought they would use gloves (now and before to prevent any fingerprints). My main concern is someone loading malicious software/firmware on the device although I could factory reset it again (setup was not complete when I started the phone).

I left the retailer and phone manufacturer anonymous here to start, but can add it later if appropriate.

How to hide "Do not disturb" notification card
Is there a way to hide this notification card?

I have Huawei P30 with an up-to-date Android 10 (EMUI 10.1.0 - Build version 10.1.0.133) and I believe this card started showing up after a recent update (which happened in the past 2-4 weeks).

I keep my phone on DND most of the time, but I'm pretty sure this card wasn't there before when DND would be on. It's just noise (since I have the DND button in the drawer anyway and it's blue which signifies that DND is on), it's occupying space, and I don't want it to be displayed (but I want my DND to stay on during certain hours). Is there a way to make this specific notification not show up - ever?

Pressing the "Disable" button actually disables DND.

Thanks.

Force Galaxy S8+ to authorize my hp
Sorry for the long, difficult problem. Anyways...

Hello, I recently dropped my phone in the pool. I wasn't too concerned because I was about to get a new phone anyway, but it turns out at some point about 2 years ago I had accidentally turned off auto-sync on everything and I lost a bunch of contacts, photos, memos, texts, etc. The display and touchscreen are both not working, but I know its on because it still vibrates for social media notifications at the same time my new phone does. I took it in to UBreakIFix and they said they tried to replace the screen and battery but that it didn't help. Something they did must've revoked USB debugging for my laptop which is my problem. Beforehand I could plug my phone in no problem and do whatever I wanted. Now I have to click "Allow USB debugging" which I obviously cannot do because I can't see the display and the touchscreen is broken. Does anyone know a way to force my phone (Galaxy S8+) to authorize my laptop? I'm trying to use Vysor to control my phone with my laptop and then I'll just SmartSwitch everything I need to my new phone. Any ideas would be greatly appreciated and any other ideas to get my data off my phone would be appreciated, too.

Thanks.

问:
Is it a viable option to modify ROM image directly instead of compiling?
I have an archive of my stock ROM with partition images inside and I have combined sparsechunks into a single images (this specific because it seems that there are various formats with ambiguous naming).
Now I am able to mount combined images of ext2 partitions and make modifications to the files/directories.

Main goal is to remove google and various other bloat, I know how to manually remove applications from android.
But I read that this is not correct way and that this might make device unstable or create various problems and that I should modify and compile AOSP/lineageos insted. (source of information is XDA though...)

Only compilation of AOSP/lineageos requires too much knowledge thought, not to mention attempting to make modifications to the project which takes hundreds of gigabytes of storage.

Will 'debloating'/'degoogeleing' ROM image make my device unstable or possibly raise other problems and something I should not do?
Or does it depend and I should maybe try and see for myself?

I know of custom android distributions like lineageos - I have this official POS (piece of software) installed currently and it has too many bugs for my taste, phone being just a tool and not a way of life for me, I don't find it appealing to wait and hope for possible resolution.


问:
Does cell service provider has ability to display ads over other apps?
I came to realize that in rare occasions when using the Android phone, Cell service provider (Mobile Network provider) shows some popup advertisements. Regardless of the app, screen I was in it always mange to draw over the screen. Recently I manged to capture the screen when it does (Se attached image).

As I checked all the app's permissions to "Display over other apps" there were nothing other than some phone manufacture related and accessibility related system apps.

I find this as an security risk as cell provider can hijack my screen. Also I don't thing this is due to a malware/adware since all the ads are related to cell network and their packages.

My question is how Android eco system enables this kind of facility?

Which mechanism or the loopwhole Cell provider might be using?

Is there anyway to disable this? (other than clicking over unsubscribe
link on ad)

As you could see in the image, I was checking emails and ad got popped over

Edit:

I do have a customer care/help app installed which provided by carrier. However I made sure it doesn't draw over apps.

Device is non-rooted, and never touched the bootloader, so might be locked.

Familiar with adb and fastboot. And adb lists the device with proper permission. However while running adb shell appops query-op --user 0 SYSTEM_ALERT_WINDOW allow | while read line; do echo -e "\nPackage: $line "; appops get $line SYSTEM_ALERT_WINDOW; done gives empty results.

Tried adb shell appops query-op --user 0 SYSTEM_ALERT_WINDOW allow also but empty output

问:
Is there a safety system to prevent overheating?
Is there currently a system in place that prevents overheating. I have recently been having issues with my mobile hotspot and I noticed that the issues I have seem to be when the phone is above 90 degrees F. (Using a battery temperature app).

When the phone is room temperature everything seems to work fine and when it is above 90 I seem to have issues. I thought maybe the wifi chip was having issues, so I manually tethered with USB and continued to have issues. To rule out my laptop, I connected the phone to my router and hardwired in my laptop. I then bought another cell phone which had the same issues. Specifically the issue I was having was full 20 Mbps and then 0 and then 20 and then 0. (Tested with speedtest.net multiple times.) So it appears to be the actual chip that connects to the cell towers. (On both phones it was doing this.)

Is there a safety mechanism in place in the android system that detects that your phone is heating up and begins cycling chips on and off to prevent overheating? I can see how for most activities a normal person wouldn't notice unless you're streaming something live with no buffer (ie: remote desktop over hotspot). Actually if it does this it would be almost genius because it wouldn't need to completely power off. It could just cycle between normal power and lower power which wouldn't be an issue for 95% of the things you do, it would increase battery life and decrease phone temperature. However, I also would be doing the 5% of the tasks were it is annoying as all get out watching the mouse cursor skip across my screen and watching windows minimize robotically with jerking updates.

Panorama app better than StreetView
Google's Street View app allows building all-round 360 panoramas, however even with the latest versions, the stiching and exposure quality are really surprisingly poor. Other similar apps have very poor ratings on the Play Store.

Unfortunately, none of the good streetview-like images I see for instance on GOogle Maps (example), give any indication what app has been used to make it.

How do I get fastboot/adb to find my device after a reboot?
I am trying to unlock the bootloader of my Samsung Galaxy J7 Sky Pro using this guide.

If I do

```<code>> adb start-server
> adb devices

I get my device as connected, however when I then reboot into the bootloader using

```<code>> adb reboot bootloader
</code>```

Everything works as I would suspect I get the boot screen with the extra text:

```<code>ODIN MODE (HIGH SPEED)
PRODUCT NAME: SM-2727VL
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
FAP LOCK: OFF

QUALCOMM SECUREBOOT: ENABLE (CSB)

RP SWREV K 2, S 2
SECURE DOWNLOAD : ENABLE
download mode !!
</code>```

Which seems ok to me.

However when run adb devices again the device is gone.  Of course if I try to run any fastboot command from this state it just sits and waits for a device.

```<code>< waiting for any device >
</code>```

Even if I try killing and restarting the sever it doesn't find the device.

The same occurs running both on a Linux machine and an OSX machine.

OnePlus 5T - Inconsistent wake lock screen notifications on certain apps (delayed or never shown)
I should preface this by saying this is a long post that has a lot of screenshots.

For months possibly a year, I’ve been having an issue with certain apps where notifications either do not appear at all or are very delayed on the lock screen. Sometimes they do appear without delay, but it's very inconsistent. The delay can be anywhere from 20 min to 2 hours.

Often times when notifications don’t appear on the lock screen they appear as soon as I unlock the phone or open the app.

The apps in question are Twitch TV and Discord. However WhatsApp and my Text message notifications never have any problems, I always see them on time and they wake up the lock screen.

My phone is a One Plus 5T that runs the stock One Plus android OS. I should also note that I only use Wi-Fi and not mobile data such as 4G.

Things I’ve tried:

There are a number of things I’ve tried which I will list here.

Twitch in app mobile notifications:

Ensured that when a streamer goes live I get notifications

Ensured push notifications are enabled

[

Twitch app phone settings:

Battery usage → Background restriction = disabled

Battery usage → Battery optimisation = not optimised

App data usage → Background data = enabled

App data usage → Unrestricted data usage = enabled

Notifications → Show notifications = everything enabled

Battery Phone Settings:

Battery optimisation → Advanced → Deep optimisation = disabled

Battery optimisation → Advanced → Sleep standby optimisation = disabled

Battery → Adaptive battery = off

Other phone settings:

Ambient display → New notifications = Wake screen

Notifications → On lock screen = Show all content

System → Recent app management = normal clear

Developer options → Standby apps = Twitch ACTIVE

Google Services Framework phone settings:

Battery usage → Background restriction = disabled

Battery usage → Battery optimisation = no way to not optimise

Notifications → Show notifications = everything enabled

App Permissions → Read instant messages = enabled

App Permissions → Write instant messages = enabled

Misc:

Locked twitch app to always run in the background (courtesy of this post)

Installed push notifications fixer app

Tried to find a setting for each app that’s not on my phone (I think you need a later one plus model for these settings), courtesy of this post.

Conclusion:

None of the things I’ve tried have made any difference so far. I have no idea if it’s the apps, android or a one plus specific issue. If it’s a one plus specific issue I might be able to root the phone and install a custom ROM but that is an absolute last resort.

A lot of people say OnePlus phones have overly aggressive memory mananagement, so that could be a factor.

Any help would be appreciated.

Thanks.

I have a 5Ghz wifi adapter in only one of my PCs and 5Ghz wifi hotspot in my Android 10 phone which gives speeds upto (433/433 Mbps) also when I use USB tethering from Android Phone it gives speed upto (425/425 Mbps)

So, What I'm trying to accomplish here is to connect one of the PCs to 5Ghz wifi (Remember I have only 1 adapter of 5Ghz) network  and another to USB tethering network using the same phone so that they are both in the same network and hence I may transfer files.

But the problem I am facing here is that the Android 10 phone is providing Different networks (IPv4 network addresses are different) for both the Wifi hotspot and the USB tethering in both the PCs.

Wifi Network Details:

USB tethering network details:

So what can I do? so that both the computers are in same networks using such connections from Android 10 phone.

Deleting images from Google Photos without deleting them from the device
I've created a folder in Google Photos with images that were in other folders. I want to delete the images from the other folders without deleting them from the device. But when I delete them, they get deleted from the new folder and the device.

Is it possible to only delete the images from Google Photos without deleting them from the device?

How can I reset my Misfit Vapor X when it won't even boot after an automatic update?
Okay, so I bought a Misfit Vapor X.  It was brand new, and worked for about an hour when it updated itself.  Now, it won't boot and goes into a boot loop when I try.

It will buzz, then show the Misfit logo for about ten seconds, and repeat the process.

I pressed the main button and the bottom button and got the watch to go into the recovery screen.

From there, I can choose:

START

Shipping Mode

Restart bootloader

Recovery mode

Power Off

START goes into the boot loop

Shipping Mode gives me a screen of red letters that show this:

SHIPPING MODE
PPG Fail or Timeout!
LED1 3216, LED2 3832
IR 9003

Recovery Mode goes back into the boot loop

Power Off doesn't, and instead goes to the boot loop.

I googled the above cryptic message without any useful result.

I can't get ADB to see the watch (I'm not an expert, so I may not be doing that right...)

USB tethering not working after using MirrorLink
Sharing was workink fine until I started using MirrorLink. Now when I try to share internet via USB cable i get greyed-out option saying "Port USB is used by MirrorLink". When i go to MirrorLink tab i get greyed-out option too, saying "USB tethering is turned on".  It looks like the Apps are fighting over USB connection. Can I somehow prioritize USB? I tried to turn off MirrorLink app but It didn´t fix the problem. Any ideas what should I try next?

android's linux kernel scheduling mechanism vs harmony os's deterministic latency engine
I was reading upon Harmony OS and found that android's Linux kernel scheduling mechanism has some limitations as mentioned here: https://harmonyosofficial.com/

From Harmony OS website mentioned above:

Unlike Android which uses the Linux kernel’s scheduling mechanism,
Harmony OS uses a “deterministic latency engine” that provides
“precise resource scheduling with real-time load analysis and
forecasting and app characteristics matching.” The result is a 25.7%
and 55.6% improvement in response latency and latency fluctuation
respectively. In addition, Huawei says the microkernel can make “IPC
[Inter Process Communication] performance up to five times more
efficient than existing systems.”

Video tweet with explanation

https://twitter.com/HuaweiMobile/status/1159725806320594945?s=19

I didn't understand these limitations properly. Can someone explain me in easy words along with the use cases?

How can this Harmony OS's new kernel benefit users/developers? Also, I'm a software engineer so I understand terms like scheduling etc. But I don't know how Linux Kernel does it vs Harmony's kernel


问:
Is it possible to have manageable encryption when using TWRP/unlocked bootloader and modified ROM?
Every single piece of information I've come across warns me about issues with sane encryption when using custom recovery, unlocked bootloader and non-stock ROM (as in modified, not community AOSP based). Since I need following things:

ability to back-up/restore data from the recovery if needed

root, which means I have to flash things manually after flashing ROM

ability to flash/update the ROM (since this is the only way, OTA wont work in my setup)

I can live without the 1st, but there is no way to let go of the rest 2. If I enable encryption I wont have access to data from recovery or rather I will have access to encrypted data. This isnt the problem normally until I need to flash over updated ROM or swap ROM - now there is an issue because encryption key will change.

There is also no point to have password-locked TWRP since with unlocked bootloader it is easy to sideload new one.

Does the headache-less solution for power-users exist?

Samsung Galaxy A70 stuck in boot loop
I have a Samsung Galaxy A70 (A705FN) which worked fine until i decided to update to Android 10. I downloaded the update and everything was fine until the phone restarted and got stuck in a boot loop. I did some research and everyone suggested that Wipe Cache would do the trick.

But the problem is i can't access recovery menu. When hold down power and volume up buttons a blue screen pops up and says Installing Updates ... and goes 0 to 100% and then restarts and i'm stuck in the loop again. No matter how many times it doesn't do anything.

I tried to use third party recovery modes like TWRP but i did not enable usb debbuging or unlocked bootloader so this is not an option for me.

So ... how do i fix this? Thanks

问:
What can cause a file to self destruct itself?
I had a file on my device (Huawei Mate SE, Android version 8) which I downloaded few months ago.

Few days ago, the file disappeared. It's just gone and I can't find any trace of it. I'm 100% sure I did not delete it myself.

No other file is gone, only that one. This is the first time such thing happens to me, on any device.

If it matters, the file is a song (audio only mp4).

What can cause such a thing?

Additional info about the file:

It was downloaded via a browser on a desktop computer, sent to myself via email and downloaded on the phone from that email. I deleted the original file on the computer.

I don't know if the file had any special protection.

I have several other files downloaded in this exact way, all of them are fine.


问:
How was the bootloop fixed on OnePlus 7?
This is a weird question , in the sense I recovered from the boot loop but don't know why and how and hoping I get some pointers from the possibly incomplete information.

I recently applied monthly update on my OnePlus 7. For those who aren't aware , OnePlus downloads the complete ROM instead of update if it detects root or unlocked bootloader (good thing). This is applied as local update. Before applying the update, one needs to uninstall those Magisk modules which aren't a part of the Magisk repo to prevent bootloop and switch slots in Magisk as per the OTA upgrade notes.

I had done this several times and this time it went fine and it booted up normally. Yesterday, I needed to reboot for a totally different reason and on doing so entered into a bootloop. Long press  power didn't shut down the device and none of the usual key combination tricks worked. Fortunately, after a struggle, I managed to get into recovery mode of device using  power +  vol down. My first suspect for the bootloop was that I had was that I was careless by not uninstalling non-Magisk repo module , so here's what I did after fast booting into TWRP

Cleared cache and rebooted with same result.

Flashed this zip to enable Magisk core only and rebooted. No luck

Switched slots hoping that the pre-update slot would boot up but again no luck.

I was resigned by this stage to doing a factory-reset since I couldn't think of any other solution. Since the full ROM was already there on the device , I tried installing it through TWRP ( I know it won't work, since it is not a fastboot ROM, but then I was ready for factory-reset). It showed installation in two stages , stage 1 was successful but stage 2 stopped mid way with a warning fstab not created (IIRC) . This flashed twice. Again tried to reboot , no luck.

Booted into TWRP and again disabled all Magisk modules and rebooted, Bingo, it worked ! (I may have switched slots, don't recollect as I was reckless enough to try anything)

I am sure trying to flash full ROM had something to do with revival because on booting I had a stock kernel, instead of custom kernel. Of course, I had to flash Magisk and modules to get back to business  but luckily data was intact.

Long story to make sure no facts are missed. Now my question in two parts:

What else could I have tried?

How did flashing the ROM (unsuccessfully) help?


问:
Can magisk replace files outside of /data/system?
I need to replace a file in /data/data/... Is it possible with magisk? And if so, how?

I've read the developer guide multiple times, and it seems that it's possible using an overlay system - which I absolutely fail to understand.

Another way of replacing the file could theoretically be using shell during the module's installation process, but that gives me "operation not permitted" (+ it's not an "overlay" because we're directly modifying the file).


问:
How to get checksum for the running firmware?
I have seen other questions and answers that say given a new phone shipped from a retailer, it is only possible to verify the integrity of the firmware by comparing checksums.

However, I'm not sure how to get the checksum of the currently running firmware on my device. Is this even possible? I may have misinterpreted the other advice as comparing checksums for downloaded images, but I am specifically looking to check the firmware that came loaded on the phone against a valid source before re-imaging it if that's what I decide to do. Hoping for generic advice, but manufacturer is LG if it matters. Please suggest tools and process.

Final note: The phone has been used since it was received, so if there is a way to capture the pre-loaded firmware, I want to make sure it is not affected by any software/user option changes that would be made after the device setup was complete. I'm guessing I want to get a checksum of the current software version, so not sure if I have to make an image first and if that firmware image that is created would be static.

问:
Is there any way to turn an Android device into a Google Home speaker and thus add it to a speaker group in Google Home?
In Google Home there is this feature called "speaker groups" which allows you to play the same music simultaneously on several speakers, in several rooms in the home, etc.

I use this to play music in my entire home. However, there are still some rooms to which I would like to add speakers.

AFAIK, only Google Home speakers and Chromecast devices can be added to speaker groups at the moment.

I could go out and buy even more Google Home devices, but I have some spare Android devices and good speakers to hook them up to, so I figure that would be cheaper, better (in terms of sound) and environmentally friendlier.

So basically, to be clear: I want to have an Android phone hooked up to a speaker behave pretty much like a Google Home, and play audio in a room. I want to be able to add it to my speaker group for the entire apartment, so that it can play music along with my real Google Home/Nest/Chromecast devices, in sync with them.

It seems that there previously was an app that made an Android device emulate a Chromecast. That app was called CheapCast but it now seems to have been taken down.

I also found an app that did let me receive Chromecast on my Android, but it did not show up in the Google Home app so that it could be added to a speaker group.

Is there any way to achieve this? I can use root, Xposed Framework, Magisk modules, custom roms, whatever is needed.

The Android devices I have lying around are running Android 9.

Bluetooth devices keep hijacking the other device's connection on Google Pixel 2
On my Pixel 2 running Android 10, in the Bluetooth settings, there are several devices listed under Previously Connected Devices. My Bluetooth headphones are at the top of the list while my car's Bluetooth is at the bottom of the list.

I often listen to music on my headphones while walking to my car. When I start my car, my car's Bluetooth pairs with my phone and hijacks the audio so that it begins playing through my car's speakers.

Is there a way to establish connection priority with Bluetooth on Android so that if a higher priority device is already connected, then a lower priority device won't steal the connection?

Or is there a way to turn off auto-connect for some Bluetooth devices? After reading this, I assume that there is not: https://support.google.com/android/thread/41125271?hl=en

I'd like to keep my car as a paired device if possible so that if I ever do want to play music through my car speakers, I can manually re-connect to my car without having to pair first.

Empty spaces in ADW Launcher dockbar
I use the standard ADW Launcher that ships with CyanogenMod 7 and have noticed a problem with the dockbar. NOTE this is the "hidden dockbar" you can reveal with a swipe, not the normal Android dock (LAB/RAB).

There is enough space for 6 icons on my dockbar but I can only add 4 before they start flowing off-screen to the right. In other words positions 1 through 4 have icons but positions 5 and 6 can't be used (first screenshot). Dragging a new icon onto them places it at position 7, which can only be revealed by scrolling the dockbar sideways (second screenshot). It's as if ADW thinks there are icons at 5 and 6 already but there aren't.

I have tried using Reset ADW in the settings but while it reset many ADW features it did not reset the dockbar, or solve the problem.

There was a time when only position 5 was locked as blank and position 6 held an icon, but in dragging icons around to try an get one to go into position 5, position 6also became locked as blank.

Any way to force change an Android device screenshot folder location / destination?
Is there any way to force an Android device to change it's screenshots file folder / destination location?

Like ADB command or something?

Something that is native and permanent?

Something that isn't app based (I don't like PinSync and FolderSync as those are battery hogs too)

Specifically for my Samsung Android device. Samsung infamously add their Screenshots folder inside DCIM > Screenshots, instead of what supposed to be in Pictures > Screenshots on virtually all their Android devices ever shipped. Despite users asking for this change, the problem still exist today.

I don't like this experience because of these such experiences :

Photo Backup services like Google Photos or OneDrive auto backups your Screenshots too.

I believe Screenshots in the cloud should be a manual backup. Not all of them are so important to be wasting your cloud storage

Especially if your device has the Volume button on the right side, and Power on the left side, which makes accidentally screenshotting very easy.

Literally your Photo Roll will be littered by accidental screenshots.

Some OEMs Android OS have their manual Screenshot folder location changing on their Settings apps, but not Samsung's One UI. And apps such as Google Photos doesn't support specific folder syncing yet. They only annoyingly support parent folders for now.

But if possible, I'm asking for a universal solution to this. That will work to any device / OEM. I don't like rooting, but if that's the only solution you know of, please tell me.

I'm sick and tired of this. Please help me.

Can't load certain sites on phone over Wi-Fi
When my phone is connected to Wi-Fi, certain sites won't load, especially https://www.nytimes.com/; Chrome's progress indicator shows a little bit of progress, but never gets past that. Other sites are fine.

Various notes:

If I turn off Wi-Fi while it's in this state, I get ERR_CONNECTION_ABORTED ("This site can't be reached"). So my assumption is that the progress indicator's little bit of progress is just because of successful DNS lookup, not because it's actually managed to connect to the site.

This issue is specific to phone + Wi-Fi:

This issue does not occur when I disconnect from Wi-Fi and let my phone use mobile data.

This issue does not occur on my laptop (which uses the same Wi-Fi network).

This issue occurs on both my own Wi-Fi network and my sister's; but we both have the same ISP, so that may not be a fully independent test.

This issue occurs in both Chrome and Firefox, and seems to affect other apps that connect to those sites.

But, interestingly:

In the case of NYTimes.com, it seems to bear some relation to cookies, in that it works in incognito mode until I log in. But logging out does not fix it (perhaps because it leaves other cookies?).

Twitter (https://mobile.twitter.com/) sometimes loads successfully (albeit slowly), sometimes not. Twitter has a lot of local storage stuff (it shows some of its page boilerplate even when I have no Internet at all), so I'm guessing that this has to do with dynamically choosing different backends, some of which I can connect to and some not? (But that's just a guess.)

This is pretty consistently the case. The only exception I can remember is that the first time I tried loading NYTimes.com in incognito mode, it worked immediately afterward outside incognito mode as well.

This has been the case for about a day and a half.

I tried changing DNS settings (first to use Google Private DNS, then to use Cloudflare); no effect.

I'm running Android version 9, moto x4, google_fi.

How to instantly wipe an Android phone in case of arrest?
A Belarusian friend asked me this, but I can't find anything on my own. Protesters in Belarus are beaten once arrested until they give up the pin code to the phone.

So, if he could give a pin code that would immediately trigger phone reset to factory settings, or erase data, or even show a dummy profile, that would at least protect their family and contacts and limit the extent of accusations.

It would be nice if the phone could be used afterwords. Protesters may be given their belongings back after detention, and having a working phone is an advantage if they land in a hospital or just outside the detention center with none to pick them up.

So far I suspect that to have this functionality one has to fork Android or LineageOS. Is there already such a fork?

Why Android? Because back in Belarus, iPhone is much less popular than in the US or EU.

Navigated to Settings > Storage > App directory setup.

Enter /storage/0000-0000/LectureNotes/ in the custom app directory.

I keep getting the error Cannot create custom app directory, will use default app directory!, and can't figure out why this is.  Surfing the web and this site yields solutions which do not work on my device (e.g. ).

What am I doing wrong?  Should I be using a different path?

Note: I'm friendly with Linux, but a novice with the Android file system.  In answers, please provide (1) a solution to my problem, (2) an explanation, and (3) an explanation of why I'm running into this problem (if it's not too much trouble).  Thanks in advance!

问:
Why my Android suddenly stopped connecting to my Mac?
I usually use my Android device (Samsung Galaxy S7, Android version 8.0.0) to debug my app from my Mac (developer option enabled). Usually when I connected my Android, the Android File Transfer will start to jump around to complaint that it can't browse my Android, and on my Android, it will ask some kind of permission for the computer to access local files. After I say yes, the Android File Transfer will immediately show my Android file contents. But even without that, my Android will usually still showing up on adb devices.

But today, nothing showed up on my Mac, at all. Android Studio doesn't see anything. adb devices doesn't show any device connected. The Android also doesn't show any sign that it's connected, like a kind of notification that it's connecting using MTP or PTP. Now there's no such notification. The Android File Transfer also silent. If I open it manually, it shows "No Android device found. Please connect your Android device with USB cable to get started." But the Android device is still charging.

I tried using different Android device, using the same cable. The Android File Transfer happily jumped around at the first chance. So it's not about the cable either.

How can I fix this?


问:
Why does my mobile data work only on hotspot?
I own a Samsung Galaxy A71 and I'm on Reliance Jio network.

When I had bought this phone and put a new Jio SIM on it, my mobile data worked fine, but the hotspot didn't. My laptop browser said 'DNS not found' or something along those lines. I solved it by updating APN settings.

Fast forward to eight months.
Right now it's the exact opposite. My mobile data works very rarely. I get maybe a bar of signal at best. On 4G network I get 20-30 Kbps. A WhatsApp message goes through after 10 min. But if I connect my laptop through the hotspot, suddenly the data works seamlessly without any problems. A YouTube video on the laptop at 720p can load without any buffers, the same cannot be said on the app in my phone.

Any idea why this would happen? Something to do with the APN? Or something with the network?
Also, the JIO tower is right next to my house. Why would I get only a bar of signal?

IP blacklisted - unusual traffic - possible malware?
Over the past month I've had about 5 or so occasions where Google force me to do a capture on a normal search, saying that there is unusual traffic from my device.

Recently, past few days, I've had a few specific websites and apps timeout while all other services work as normal.

So, I decided to look into my devices traffic. I found this quite difficult on an android device. But what I did find is that my ip address appears on two blacklists. One of the blacklists state the following:

```<code>This IP is infected (or NATting for a computer that is infected) with an infection that is emitting spam.

Note: [ip removed] appeared to be suspicious because it was using the following name to identify itself during email connections (port 25) via the HELO/EHLO smtp commands: ".".
</code>```

I have installed avg antivirus and performed I full scan where no threats were found. The only email client I use is gmail which does not use port 25. Avg does not have a firewall so I have not yet blocked outgoing requests on port 25.

How might I find out what is sending requests over port 25?

How might I remove it

Are there any other steps I should take?

Please help.

Thanks.

Edit 1: I have factory reset my device and have a different IP address. As soon as I went into chrome I was greeted with "we have detected unusual traffic from your computer network" and the new IP appears on two blacklists for the same reasons. Although the connectivity issues to specific websites have now been solved.


问:
Android telephone with a screen that works inside the rain/water spray just as well as in dry region
Well I keep having to fight with all telephones I buy. often wishing back to the time when you could just call instead of having to type on a touch pad.

Not because I don't like it, but because the smart screens seem to live their own lives when they get wet/droplets fall on them.

In my work and generally whereever I am it's more often than not wet and I need to be able to communicate with people in those weathers. I could of course wipe the screen, but within seconds the screen is doing its own thing already. (Currently owning a pixel 3). On top of that even in dry weather the screen seems to have a lot of "ghost" clicks when I touch it, that or it doesn't recognize my touches at all...

Is there a way I can make the screen less random and working better in rain?

I've tried several models, pixels nexus phones one plus, samsung... All seem to fail me.

import pem file containing multiple CA certs
Using Samsung S4, Android 5.0.1, not rooted.
Recently I have found at least two websites that the Chrome browser on Android 5.0.1 reports https is not secure. This is because the phone does not have the root CA cert required installed. I know how to load individual CA certificate pem files into the user list using the Security menu and "Install from device storage". I wanted to load all the current ones. I had to get "SectigoRSADVBundle.pem" from Sectigo.com as this CA is used by one of the local government websites which must be newer than Oreo release but and the other pem I found in the Oreo pem files

I tried concatenating more than one pem file but it only loads the first entry in file. I tried making a pem file using the Oreo pem files so it had this layout:

```<code>-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
</code>```

but only the first pem is loaded. I most likely do not need all of them but I have no idea which files are newer than my Android built in system list.

Is there a list of new CA created since Android 5.0.1 (or a way to build the list) if I have to load them individually?

There are 137 pem files is there a way to load all CA certs using just one file?

Whenever you put a cert in User Certificates section when the phone reboots the is a warning message, so my next task will be investigating moving it to system list


问:
Are there any smartctl similar tools to detect (eMMC/Nand) storage flash failure in advance on non-rooted android?
So far, I have two android phones which become kinda brick due to storage failure.

One phone suddenly missed many apps and files one day. And another one does not accept correct lock password one day.

When I try to look into mobie phone storage related topics, I am surprised that so litte info I can find.

I can not even find an app to tell what my phone's storage type and model are. I tried the famous AIDA64, it doesn't really give me anything about my flash drive. I can not even know if it's a NOR, NAND or eMMC.

I have some/many mobiles and some are rooted and some are non-rooted. I am wondering if I can find a general solution to detect flash drive failure in advance so that I can backup properly before it failed to boot and lose data. (I use smartd/smartctl on desktop OS for this purpose)

From my bad experiences, I really don't have any trust on mobile phone storage anymore. I have some other mobiles/pads/tablets broken too without knowinig what the real problem is. I guess they might be due to flash drive failutre as well.

Thank you very much for your help.

Droidexplorer cannot find device. Galaxy Note 4
I accidentally deleted the entire photos folder on my Galaxy Note 4. My quest to recover the photos in this folder has led me here. I have installed the SDK on my PC (Win7) and droidexplorer is all set up, but it won't detect the device. Yes, developer mode is activated and yes, the USB debugger thingy is turned on. Droidexplorer sounds really super helpful, but it's not detecting my phone.

I saw several other threads about platform-tools needing to be reverted to an older version, but I can't figure out how to find the version I need, and it is difficult to understand some of the posts/events/etc. between stackexchange and github because I am not super experienced with coding.

I got this far because I'm not very good at giving up on things, but I am just about out of time to spend on this problem.

About the device:

Samsung Galaxy Note 4 (refurbished, in case it matters

Unrooted. Not necessarily opposed to rooting the phone, but if it would wipe memory that won't work.

I need help figuring out why droidexplorer cannot find my phone. Do I need to replace the platform-tools folder? Is it something else? Is the damn thing too old for this?

Find APNSourceService
I have a TicWatch Pro 4G. As some may know, the watch only supports Vodafone. But from what I have seen, that's mostly down to the fact of the correct APN for other networks not being available. After looking in the usual places like /system/etc/apns-conf.xml, I found most APNs to be present there. However, the menu to choose the APN is always empty. After a lot of digging, I found this thread on here:

Where apn configs are saved in Android?

In there, it is mentioned that there is such a thing called "ApnSourceService". However, there is basically no information available on this except that thread and some mentions in the source code, one of them being in the TelephonyProvider.
In that thread, it was said, that one can disable such a Service using Magisk. However, I found no information on which service that might be, or where to find any clues. Also I looked into system-apks to find any mention, but I didn't find something useful.
I also tried listing running services, but at least I didn't find something useful in there.

Also I'm not really a professional, it might well be I'm completely on the wrong path with the "ApnSourceService".

How to create image of internal storage to attempt data recovery?
I accidentally deleted an entire folder of photos a few days ago on my Galaxy Note 4. My PC was also down because of a failed hard drive, so I was unable to back up my phone prior to this accident.

At that time, I didn't even know what "adb" meant; now I have droid explorer and Android SDK on my PC, and have worked out how to get my PC to detect my phone. Now I want to make an image of the internal storage; there are lots and lots of other threads about this, but none of them explain the commands people are using. I have been very careful not to use my phone for much of anything (it has been set to airplane mode to reduce the chances of things writing to the drive), but I can't keep that up for long.

Can somebody please explain what commands I need to use in order to get an image of the internal storage? I keep seeing information about "booting in recovery mode" and bootloaders but I have also seen people discussing dumps of internal storage without these things.

I just need to check if my photos are still there. It's pretty frustrating to figure this stuff out with very little knowledge of coding and zero knowledge of Android software, so if somebody could help me figure out what to do next and be thorough with explanations, that would be excellent.

Restarting a bricked Android phone
My Lenovo K8 Note has bricked. I am able to format it with ‘Smart Phone Flash tool’ (Mediatek). I wanted to know how I can load Android on it and restart it. I tried to format it and it was successful. When I tried various versions of Android (Nougat and Oreo) the phone did not start. While I had loaded Nougat nothing happened after I downloaded it on phone, on downloading Oreo, the welcome screen went into a loop. Presently the phone is in formatted condition.

I wanted to know the following:

If I format the phone and simply download the latest version of Android in it, will the phone start working? (something like assembled PCs where I can format the HDD and load a version of Windows for it to start). If so, which version of Android should I use? Pls. point me to the downloadable ROM file. (the phone originally came with Nougat)

If the above technique is not possible, what should I do to revive my smart phone? Before the phone bricked on its own, I had not unlocked the bootloader (never had any requirement to do so).

I don’t want to buy a new phone in the present economic condition. Hence, pls. guide me on how to revive the device. Any pointers will be gratefully acknowledged.

Why does typing "One way they can fit it in" as a text message create a link to Google Maps?
Today I noticed that when I typed and sent "One way they can fit it in" in the Facebook Messenger app for Android, it created a link (underlining the text, see first image below). When I follow this link, it prompts me to open the Compass app or Google Maps.

I have found that it does not work on the Messenger app for iOS or Windows, but does work for other messaging apps within Android. When opening the link in Google maps, it responds with a message, "No results found" (see second image below).

Can anyone else reproduce this behaviour? Does anyone have any idea what Android feature might be causing this phenomenon?

Edit: I am on a Samsung S8, using Android Pie, although my friend can also see this on his Huawei P10. This behaviour happens on both Facebook Messenger and the default Samsung Messages app. I have tried several other similar phrases, but I have found that the general form of text that forms this link must begin with "one", end with "in", and have three or more words in between, one of which must be the word "way" (For example, "One foo bar way hello world in" creates a link).


问:
Attempting file recovery (deleted photos) on Note 4 via accessing /data/userdata; rooted phone, patched adbd, but now USB debugging won't work
I made a post about this yesterday, and I managed to make a lot of progress today, but I'm stuck again, and I am trying to decide what to do. I am not really experienced with coding, but I happen to be very good at teaching myself how to do something when needed and also very bad at giving up.

Below is a summary of my progress thus far:

INITIAL PLAN

Install Android SDK, drivers to PC (Win7, 64 bit)

Root phone (used CF-Auto-Root)

Patch adbd to allow root permissions (installed adbd insecure and SuperSU)

Access /data/userdata

Get image of /userdata, attempt to find files

I am stuck at step 3. I have adbd insecure and SuperSU, but using either of these causes USB debugging to be disabled. Regardless of how I toggle things, I lose my connection to my PC and cannot enable USB debugging.

Some research uncovered that there's something called SELinux that is preventing me from enabling USB debugging while adbd insecure is enabled (patched adbd). There are posts in the adbd insecure thread on the XDA forums from other people (check the last page) describing a similar problem:

https://forum.xda-developers.com/showthread.php?t=1687590

And one post at the end explaining that they fixed it with an app called SELinux Switch:

https://forum.xda-developers.com/showpost.php?p=79689054&postcount=267

SELinux Switch would allow me to turn off the protection preventing adbd insecure from working. Can I get some feedback about this? I'm not enjoying this stuff, and I really need to get back to other endeavors, so it'd be a one-time use, and then I will probably uninstall it from my phone because I won't need it.

ALTERNATIVE PLANS

I also have two alternative "paths" I could take to attempt to recover the deleted photos. I'd rather not do that right now, because I don't think I have time, and because I am trying to avoid anything that would overwrite the deleted photos, but they exist nonetheless:

Alternative 1: Droidexplorer and busybox

I already have droidexplorer installed on my PC and my phone is rooted, so I guess I could install busybox and see if droidexplorer can recover the deleted photos.

Alternative 2: Magisk with/without busybox

I would rather not do this, because it sounds like it would take the most time and more monkeying around with internal storage, but apparently adbd insecure isn't an active project anymore and most people use magisk for rooting, etc. This is an alternative, but it's the least attractive option.

What do people think? For now I am going to try the SELinux switch, since it seems the simplest way. If people could please try to avoid using too much jargon and explain commands, etc. it would really help out; that way I wouldn't need to look up unfamiliar terms first.

I am currently running Android x86 version 6 in Oracle Virtual Box.

My intention is to run some software my company creates and to test it without the need for a physical tablet.

Is there a way to fool the software into thinking that encryption has worked and not actually encrypt it?

The reason the software wants an encrypted device is that in the real world the device will store customer and financial data. In my test system its all fake data so i dont care about encryption.

People should just read my other questions if they want to know the background; basically I deleted an entire folder of photos on my Android by mistake, went through the trouble of learning how to root phones and use adb.exe, etc. to try and recover them, only to be blocked by SELinux.

I got stuck with SELinux because the kernel in Android 5.1.1 apparently disallows permissive mode in SELinux (or changes from enforcing mode to permissive mode). I didn't have time to learn how to decompile/edit the kernel, so I tried a shot in the dark with an app called DiskDigger that some people recommended (no, I am not a secret advertiser, I am being 100% honest). Surprisingly, DiskDigger worked, and recovered way WAY more than I expected, even some photos that may be from a previous user (refurbished phone). I was surprised that much was recovered; I did keep my phone in airplane mode almost the whole time I was working on this to prevent automatic updates, but I also installed several apps along the way and rooted the phone, so I guess I was lucky or something.

Now for the question:

If DiskDigger was able to do this, it must mean that it was able to get into files that required root access; SuperSU verified this because I had to grant DiskDigger permission to do so. What is it about DiskDigger that enabled it to get past SELinux when I could not?

Is it because it was verified by Google Play as a trusted app? Did it have some special identifier from google that allowed it past SELinux? If there's a way to copy whatever allowed DiskDigger access, maybe other people wouldn't end up getting stuck like I did.

Anyway, that's all. I'm probably not going to have to do this again, but thank you to the people who tried to help me out. If I ever have to delve into this stuff again, I'll be back.

No OS installed message for specific ROMs
I'm having troubles with installing ROMs. I've been using a custom ROM (crdroid) on my Redmi 5 plus device for quite some time. I have recently decided to give another custom ROMs a try and downloaded Resurrection Remix and Evolution X. But I can't install them as after flashing, TWRP is saying there is no OS to boot from. But when I flash CrDroid back, it is booting perfectly fine. Here's how I am flashing ROMs:

First I'm wiping Dalvik & Cache, cache, system and data. Then I'm just flashing the ROM's zip. The strange thing is that it is working for CrDroid. I even tried wiping internal storage and formatting data but still no luck. Right now I'm posting this from CrDroid as I put it back.

Stuck On firmware update after two days!
I got locked out of an account and I need my phone to verify myself. It was dead so I plugged it in. I tuned it in at about 7% and it said firmware update... this used to happen with my old phone and I’d usually take the battery out but this phone doesn’t have a removable battery so I let it die and decided to try again the next morning.

I plug it in again, this time at 2% just in case and oh wow it does the same thing and I even tried a different charger and plug location. I might be locked out from my phone and account forever because of this, what can I do?

Unable to click next on MIUI 8 Welcome Wizard due to dead screen area at bottom
There is one non-rooted, factory-reset phone with MIUI ROM whose bottom 10% is not functional.

Screen replacement is the last resort, but if I can make some sort of software tweak to make it past the welcome screen to later root and use it for some unconventional use, it would be great.

Tried to find around following things but couldn't find the solution

Bypassing the welcome wizard

Force rotate device on the welcome screen

Any other suggestions are welcome!

Formatting Play Store review text
I wrote a fairly long review with 4-5 paragraphs, but when posted the Play store seems to strip out all the newlines and just have a giant wall of text instead. I also tried using simple html (just the
 paragraph tags) which did not work either.

Can the review text be formatted, and if so how? I wish HTML or BBcode was supported, but that's certainly not the case - still, maybe there is some conventions to get basic formatting in?

How to recover deleted photos from a specific directory(folder) in non-rooted device?
Some bad cleaner app deletes all my photos stored in a directory(folder) which is created manually by myself (for example, /sdcard/myphoto/).

I tried some photo recovery apps. But none of them recovered those photos and none of them provides a feature to recover photos from a specific directory. All recovery apps just scan the entire memory and restore all deleted photos once. (Actually most recovered photos are not deleted at all. I have no ideas why they are recovered... Anyway)

Are there any ways to recover deleted photos from a specific directory in non-rooted device? I am explicitly sure which directory those photos are, and I just want those photos only.

Thank you very much.

PS: I know there are questions about photo recovery. But mine is different. The main focus of this question is "from a specific directory".
