Success. Even if I can't explain how/why. I took my phone and my muscle memory "remembered" the correct pattern. At first I was happy with that, of course, but then I realized that it was the pattern that I tried a dozen times in the last 2 days. I also wrote down all patterns that I tried and it was the very first!

How come it suddenly worked? Now knowing the pattern I locked my phone again and unlo... wait. I was in. No pattern any more. it just disappeared!

I opened the settings app and searched for the security settings for "display lock". Before, I could decide between "PIN" (numbers only), "Password" (alphanumeric) and pattern. "Face unlock" and "fingerprint" were additionally available AFTER I set up a display lock.

But now I can only choose "unlock password" which is a fixed length (6 digit) number. Why do they call it "password" if it's just a PIN?!

So... why are the other options gone? Why can't I choose the pattern anymore? Why did it suddenly disappear? Questions after questions.

My system information tell me that the phone still runs with android 10 and EMUI 10, the last security patch was on "01.07.2021" (july 1st). Also "USB debugging" was disabled. There was no software update for a long time.

I am glad that I can use my phone again but I felt like the dumbest person on earth since I own a repair shop and I repair smartphones since 2010. Every time a customer tells me that he did not make any backups (what I did!) and that he did not set up any recovery option for his phone, I get a little angry with him.

And then I could not access my own phone even I set up

• huawei ID
• google "find my phone"
• "Lost android" by http://www.androidlost.com
• SMS commands (like unlocking my fckn phone!) by http://www.androidlost.com
• USB debugging with an authorization for my computer but nothing of that worked.

In conclusion: I may not be as stupid as I felt and I'll never get an answer on how that happened. But I'm very happy.

thanks for your time @alecxs

Thanks to @alecxs for pointing me to https://stackoverflow.com/questions/68540618/intent-for-google-play-store-manage-apps-device-my-apps-updates-does-not , that does almost exactly what I need.

The GPS intent is as follows:

Action  : com.google.android.finsky.VIEW_MY_DOWNLOADS
Package : com.android.vending
Class   : com.google.android.finsky.activities.MainActivity
Target  : Activity

I used https://play.google.com/store/apps/details?id=rk.android.app.shortcutmaker to make a link to the Manage Apps & Devices' Overview page, which makes my life easier now.

The recent version of Slack v22.01.11.0 for Android I can see on https://apkpure.com/de/slack/com.Slack defines in it's AndroidManifest.xml android:minSdkVersion="26" so this app requires at least Android 8.0.

The Galaxy S6 comes (according to https://www.gsmarena.com/samsung_galaxy_s6-6849.php ) with Android 5.0.2 (Lollipop), upgradable to Android 8.0 (Oreo). So if your device is fully upgraded to Android 8 you should be able to install Slack from https://play.google.com/store/apps/details?id=com.Slack or from a web site that provides the APK like https://apkpure.com https://apkmirror.com ...

I just got my Fairphone 4, and, overall the device is nice, but I can't get used to the notch.

Since the display aspect ratio is super tall anyways and I can use a bit more bezel on the bottom as well (for a keyboard attachment that I built and used on my last phone), I figured, I'd use wm size over adb to just reduce the screen's vertical resolution and thus create bezels on top and bottom.

But after I did that, this is what happened:

Sorry for the bad picture quality.

What happened is, it didn't remove the rounded corners and/or the notch, it just moved them farther down. So apparently, the OS doesn't seem to render the pixels behind the screen cutouts at all, and when I made the used screen area smaller, it just moved those dead zones with it. Even if I shrink the vertical resolution to 1000 pixel (which is less than half), the behaviour stays the same.

Is there a way to disable that functionality?

I want to end up with just a square display area.

It would be best if I can get that only with adb/onboard stuff. If you are recommending an app for that, it should be one that doesn't have ads/microtransactions.

This is not a threat. If you google filename it shows up on androidhost and scribd which is highly likely to be created by some app for its functioning and not a malware script.

Google usually does not use passwords for authentication on Android. Only for the initial account set-up you have to enter username and password which is then sent to the Google authentication server but not stored on your phone.

If username and password were correct the authentication server sends back an long term oAuth authentication token (looks like a long string of random characters - usually 50 character or longer) which used for authentication and updated periodically by the server (about every month).

Therefore changing the password has no effect on your Android device. Do logout devices from your Google account Google provides a web page where you cans see all active devices and where you can log out each device if want: http://google.com/devices

Since Android 11, there is a system feature where it resets app permissions after a certain amount of time has passed and you haven't used the app. I hate this, it keeps resetting apps I use infrequently.

I know you can turn it off on most apps, but it seems to turn back on when there are app or system updates. There must be a way to disable this feature entirely or to make the default setting off instead of on.

I have tried various searches but I can find nothing. Others must have had the desire to disable this annoying feature? Any help would be appreciated!

Issue you're facing is mostly because of either of these two reasons:

1. MTP acts retarded when there are too many files
2. Windows acts dumb sometimes (switch to linux)

I don't really have a solution to either than switching to linux (as i did) for the latter

Now some REAL workaround to HELP you:

1. Connect Your phone and computer to same WiFi/hotspot or even connect your pc to the same mobile's hotspot
2. Download MixPlorer or any other file manager with FTP on your android device

then follow this guide

https://manyandroid.app/android-ftp-file-transfer-mixplorer/

Trust me learning to transfer file this way would just be a one time investment, this setup will help you forever!

I would like to capture TLS handshakes coming from Android. I was able to install a certificate using https://android.stackexchange.com/a/70123 , then I started a server:

openssl s_server -key my_site.key -cert my_site.crt -msg

and I set a proxy in the Android Emulator:

127.0.0.1:4433

but if I browse to any pages on the Android device, I get this result:

ERR_CONNECTION_REFUSED

and this result in OpenSSL:

<<< ??? [length 0005]
    43 4f 4e 4e 45
ERROR
24500:error:1408F09B:SSL routines:ssl3_get_record:https proxy request:../
openssl-1.1.1l/ssl/record/ssl3_record.c:325:
shutting down SSL
CONNECTION CLOSED

What am I doing wrong?

Solved after thinking about it a bit more:

On mqtt client app (that runs on the android hotspot) i've set the broker address as "localhost".

On the ESP32 cam alarm add this lines after the wifi connection

int mqtt_server = WiFi.gatewayIP(); //ugly but works
client.setServer(mqtt_server, 1883);

hope this helps others that want to run mqtt broker directly on their android hotspot
