Did anyone else's AT&T One UI 5.1 update cause issues with their phone?
I have an unlocked S21 Ultra, and immediately after the update on 3/10:
I tried resetting network settings, factory reset, go to AT&T store and get new physical SIM, new eSIM, check back-end settings with AT&T Tech Support, ran diagnostics at a Samsung Authorized Service Center (no hardware issues found) - and nothing worked :-(. The Samsung support worker theorized that #2 was a related to #1 (as he was seeing continuous failed attempts by phone to connect with the SIM subsystem)
Last thing left was to figure out myself how to downgrade it to the last known working OS version (One UI 5.0/Android 13 update AT&T issued on 2/21/2023, G998U1OYM5DWB2 etc.) - and that fixed it!
How do I get a message/feedback to both AT&T and Samsung that (a) they need to fix this issue for S21 Ultra, and (b) suspend all forced updates until it is fixed & verified?
Also, separately, why do I have to deal with this and waste my time? I've been trying to support Android & Samsung for several years now (as Apple needs competition!) but this latest episode is really testing my resolve ...

- SIM card no longer recognized
- Phone started running hot and draining battery fast while idling
