Screen sharing feature not working fine on Android 12

[amjidkhanmohmand]

Hello team jitsi,
Hopefully, you are doing well. I just faced an error while using the screen sharing feature. I have tested it by adding the latest SDK version 5.0.2 and also the Jitsi meet's official app available on playstore. The problem is that when I click on the "screen sharing" option it sometimes started for a few seconds and then restarts my device and sometimes directly restarts my device. I think there is an issue in the task handling part for android 12.
Kindly let me as soon as possible after your confirmation.

That sounds like an Android bug, an app should never cause a restart.

Do you have the ability to get adb logcat logs?

[amjidkhanmohmand]

No unfortunately there is no bug report when the device is restarted. You can test it by yourself too. Kindly test it on any Android 12 device. I have downloaded the jitsi meet's official app from playstore too but the results are the same. I think its something with the permissions as Android 12 is a bit more secure and may need some special permissions for some tasks

If you are tailing logcat while in a meeting maybe you can catch it.

You can test it by yourself too. Kindly test it on any Android 12 device. I have downloaded the jitsi meet's official app from playstore too but the results are the same.

I did and I cannot reproduce it. It must be a bug in a device specific part of Android. I had a 15 minute screen share here:

I think its something with the permissions as Android 12 is a bit more secure and may need some special permissions for some tasks

That's not it, it would never cause a device restart.

[amjidkhanmohmand]

Ok i will try to catch a logcat and will share it shortly

[amjidkhanmohmand]

The Complete log report can be seen in the given file
log_report.txt

[saghul]

Sorry, I can't see anything weird in that log.

[amjidkhanmohmand]

I think you can find it in the end, i will try to generate another log with the problem section only

This is the complete error log for Jitsi meet's official app that is available on playstore

Looks like surfacelinger, part of the system graphics daemons crashes.

Unfortunately there is nothing we can do about that. It looks like a device specific firmware issue.

[amjidkhanmohmand]

The screen sharing is working fine with miracast etc, only failing on jitsi meet don't know why. By the way Thanks for the guidance and help. Jitsi meet is indeed a very good and easy solution for video conferencing. I will try to test it on another device with Android version 12 too.
Thanks and Regards

Thanks for your support @saghul, it was indeed the device-specific issue. I have tested it on another Android 12 device and it was working fine.

This issue is not about the web API but about the SDK.
