I have no issues with my S21 Ultra running the official stock UI4/Android 12 release. I didn't participate in the Beta release and so wend from Android 11 > Android 12.

Have you tried clearing the cache? Resetting the phone etc?


My advice comes from being a UK Samsung iPhone user.

Current Devices:
  • iPhone 14 Pro 256GB Deep Purple
  • Samsung Galaxy Buds+ > Model: SM-R175.

@AJacob: Further to the post above by @WelshPaul, can you confirm if you participated in the One UI 4 Beta? In the meantime, please try heading to Settings > Apps > Select an affected app e.g. Facebook > Force Stop > Storage > Clear Cache. Do this for all apps you're experiencing performance issues with, then press the Volume Down and Side Keys together for around 10 seconds until the phone restarts. Let me know if this helps.

Nothing to do with Beta. I went from Beta to Android 12 and no issues and infact first time didn't bother a Reset.

Make sure all apps are updated in both stores and keep checking everyday.

You can do

A wipe cache

Repair apps in same menu

Get good guardians and do the app optimisation.

Happy days.

PS. Android 12 has generally been buggy even now. Google Pixel 6 having issues as well.

I had the ui 4 update a few days ago (s21 ultra). As well as some crashing apps i notice the wifi will only use the 2.4ghz range. Before it would use the 5ghz. I have tried usual stuff  clearing cace rebooting etc  but will only use 2.4ghz

Same here! This is so annoying for a £1200 phone... I updated my S21 Ultra with the latest software and since then the lagging is noticeable and several apps like Facebook, Outlook and Google do not function properly (external links do not open, keeps crashing, etc).
My phone has more than 200 GB memory free and I've done the clear cache thing, restart the phone, etc. So frustrating...

Having issues with my S21+ today with Android Auto not working anymore with the phone. Tried the usual tricks with cache and cables without any joy. 

 

Frustrating!

Since the UI4 android upgrade everytime i recorded some video and try to share on whatsapp or telegram the video is corrupted at first the recieved video had nulti coloured diagonal lines then recently a green horizontal green line down the left side although it plays ok on my phone. it seems the latest mp4 format is incompatible with these apps anymore. It was working perfectly before the upgrade. Any ideas to cure this fault. I have cleared the main cache on the phone.
