not yet 100% android 12 compatible?

I recently wiped to lineageos 19.1 / android 12, and was installing some apps. I noticed that the Open camera app gives a black screen on startup. Before it was working fine on the stock android 11.
The same I have now with your app, just getting the black screen after granting permission to the camera.

You know of such issues?

I have Android 12 with LineageOS 19 on a Samsumg a52, the camera app and QR Scanner work fine

If neither the camera app nor QR Scanner can access the camera it has to be an issue somewhere lower down. I'd ask more about it on the LineageOS forums. I'd also check whether the front camera works

The stock camera appworks fine on lineage front and back, I had some microsoft lens? app, that was also fine. Even firefox browser as able to use both. I think it could be related the way permissions are asked and given.
