Just updated to the latest build available for my S21 plus, baseband v. G996U1U2AUC8, build RP1A.200720.012.G996U1UEU2AUC8 . 'Performance of Camera has been improved'. Ironically, now my camera doesn't work, specifically recording. Shooting pictures I have no problems. But now, whenever I attempt to shoot a video, regardless of resolution, the recording is very choppy, and I get an error 'warning, recording failed'. I have attempted to force stop the app, clear cache / data, wipe the cache partition. I also have factory reset the device, which did not solve the issue. Please investigate, any help is appriciated. It was working perfectly before. I've only owned the phone for one week.
I was able to download a third party app and tested the recording, no issues whatsoever. At least I can record like that for now only @ 30 FPS, but Camera app is definitely broken, tested in safe mode, issue persists.
