Thank you Estel for taking care of the bug reports.
I had some problems which were reported by other users here, but I don't know if they are solved because I use the stock camera. If they are not, I hope they will be soon

Last time I tried to record a video (two years ago), camera-ui2 became frozen. I was not able to kill him, I had to reboot my phone and the video was irrecoverable. But this happened only when I was trying to record something outside, after 5-15 minutes, and not when I tested it at home for 20 minutes (but nothing was moving in the front of the camera).
Since I installed the stock camera-ui after all updates, when I needed it.

And last time I tried it, it took more than 5 sec for launching it after having opened the camera cover. This is the most annoying bug for me.
