Latest update (One UI3 Upgrade) Android 11 on 14th December - Problems

[dcub]

Since the latest update my S20 is not operating correctly.  When I turn off wifi, and set sound to silent, after a few seconds it all turns back on again.  Also, if I set airplane mode on (to stop phone ringing at 2am!) it still connects to wifi.  Not sure how to uninstall the update, but something needs to be done as this is rubbish.  Thank you

having problems with my s20 too. none of the same as yours but since the update my phone is very hot and won't charge properly. charge can even go down when I'm using my phone on charge. my in call volume is quite low too and battery is draining very very quickly

Today one ui 3.0 has stopped working on my S20 Ultra. Everyone freezes, error messages everywhere! Just going to factory wipe and start again!

as with all new major updates there's bound to be a few random bugs which you should inform Samsung about. this is how they can iron out those early creases, not everyones phone acts the Same once updated all depending on apps installed etc. I normally wait a smidgin longer to update any new firmware until the second or third revised release or just bare with the bugs and ignore until they release one of many updates as they usually do but they don't know what to sort out unless us the customers send them feedback

I've had issues with my S20 5G as well since update.
My battery is draining very quickly. It was better before update.
I've 97% of apps in deep sleep, and it still drains.
Samsung only tell you to factory reset device. So you spend time doing that, backing up etc, and it might not rectify issue.

They need to release a new patch/update to rectify these flaws we're finding.
