Hi @Miara

Thanks for your report.
I was unable to reproduce this on a Pixel 7 (Android 14) and a Xiaomi Redmi SE Pad.
In general I don't think this is an SDK issue, since the camera is disconnected and I suspect its device related or something similar, we cannot do much if the camera is disconnected in this way.
A solution would be more in the direction to try to restart the camera or notify the user that their camera is not working.

To clarify maybe you can provide further information:

1. Does this happen with the device camera or an external camera?
2. Is there a way to reliably reproduce this? Maybe another app is running that uses the camera etc..
3. Has it happened on other apps on the same device?

Thanks for your update,
Regards,
Alex

Hi Alex! Thanks for your response

Regarding your questions:

1. It happens on the device camera
2. It seems to be random issue.
3. No - it doesn't happen on other apps.

If you find it helpful, here is logcat file with demo-app logs:

Hi @Miara

Thanks for the logs, we are going to look into those. We tried also to reproduce it on other devices and it happened only once, randomly, so not much luck in debugging it.
Hope with your additional logs we can do better.

Thanks,
Alex
