Problems after android 12 update on note 20 ultra

[hush12]

There are some major issues after android 12 update, please let me know if anybody else facing it

1. Battery is draining like a hell, first i thought its due to 5g connectivity but after switching to 4g network also, its draining, even i put my maximum apps to deep sleep, but still Battery is draining very fast.

2. If we put phone into power saving mode, phone becomes too laggy, there are hiccups in scrolling and apps search also takes time in app drawer. This issue was not there in android 11.

3. Network switching to frequently from 5g to 4g.. again and again. If we are in call and netwrok get switched from 5g to 4g call get disconnected. Again this was not a issue in android 11. But in android 12 its happening.

This is not a hardware issue, it is happened on after update One Ui 4 only maybe this is your software optimization issue only, I hope it will fix on your next update

This is a joke. I updated my phone this morning and now the home button does not work and I have to push a combination of buttons once I get into my open apps screen to even get to my home screen.

Hello, I have a Samsung Galaxy Note 20 Ultra also that got the Android 12 update a few days ago. It has messed up the RING app where viewing the history audio capture videos, the audio playback won't play.  The audio playback of the videos goes on and off and remains silent as if muted most of the time.  This did not happen before!  So something with this new update has affected the RING security app.  Anyone else with a RING security cam notice this problem after the update?

Same issues, just updated yesterday and since the scrolling through apps, battery drain and over heating has made the use of this phone a chore & a nightmare! Tempted to roll back to android 11 it's that bad. Hopefully this gets enough attention and they do something about it asap!

Same problems here as well. I also have a problem with the icons after update. they seem washed out like they're low resolution. I've cleared the cache, changed resolution, theme, dark mode.

Nothing seems to fix it. I was pleased with the phone performance with the previous android version.. any ideas how to fix the issues?

I'm having same issues with Note 20 Ultra.. Battery drains fast and keep losing network. Switching airplane mode on and off seems to fix but I should not have to keep doing this all day long. Does anyone know how to fix this?
