Not sure if yours is the snapdragon version, but mine being exynos the android 11 update was a mess. First time i have had issues with Samsung updates in 10 years. Initial ota update caused issues in camera app when recording video at either 30 or 60 1080p, stuttering and micro jitters making it useless, certain apps can no longer access internal memory (snapseed for example)
So i decided to do a full wipe using Odin and the Same rom, this did not solve the issues above but introduced a new one where Android Auto no longer sees the car at all (big complaint on AA forums)
Rolled back to Android 10 and all issues went away so for now ive blocked updates and will wait this out until it's more mature
Yeah i created a thread on here on the camera and several others have noticed the same issue so it's not just my issue. And to be fair apart from a bit of transparency in various areas its no different to Android 10 apart from it works less lol
If you have a dual sim setup DO NOT UPDATE.
The update RUINS the dual sim experience particularly for sms.
Obviously whichever developer was entrusted with the sms function rebuild has never had or owned a dual sim phone.
