I have the same issue. My device is Xioami Mi 9T aka Redmi K20 pro.

I have the same issue in my Xioami Mi 9 sometimes. But when open and wait to about 40 sec. the camera back to work.

We got some users reporting the same issue. @yuriy-budiyev Any idea on why this is happening in Xiaomi devices ?

[BluestormDNA]

I have an Android 10 device with the same problems thought it dosnt seem like a library problem but a problem with the manufacturer ability to support legacy android.hardware.Camera. Something that seems on the way out as api 21 has almost banished (last year it was already on single digits).

As @chaiat pointed sometimes it works if you wait. Other times it fails and provokes a main failure where further camera access is imposible (camera service down and needing to reset phone)

Anyway anything I tested that uses android.hardware.Camera2 like CameraX works perfectly.

Hope @yuriy-budiyev migrates soon. Awesome library.

up, i have the same problem

Unfortunately, same issue here with Xiaomi Mi9. I am really interested in integrating this library to my own app. Would be great to know if @yuriy-budiyev are up trying to fix this issue?

Happened to me also Xiaomi Redmi Note 9 Pro.
