What the hell have you done to my s21 ultra

Since the ui 4.0 update my phone is a bug ridden piece of rubbish.

Music not syncing with Bluetooth in car

Contacts not syncing with Bluetooth in car

Links in Facebook not working

Outlook wouldn't even open

BBC news keeps crashing

I eventually managed after various methods getting to boot menu to clear cache, no difference.

I have had just about every Galaxy since a 4, this is by far the worst update ever

How can I uninstall this update and go back to Android 11?

An update has started to roll out, see this thread . It will go to unbranded unlocked devices first . https://eu.community.samsung.com/t5/galaxy-s21-series/26-nov-21-bukg-latest-android-12-bugfix-update...

I can proudly say i have picked up my new iphone 13 pro max. Back to my roots. Samsung, android have certainly disappointed me these past few years. With the S20U camera issues and now buggy softwares that are being released was the final nail.

This is all very annoying and disappointing. What a train wreck!

No, you're wrong.  By phone is a piece of ***** now.  Literally nothing works correctly.  Thanks for nothing.
