Android Central Question

On July 1st my S22 received an update. 10-15 minutes after every restart the S22 works fine. After that I lose signal completely (circle with line instead of bars).

I put my Tello SIM into a note 8, no issues for the hours I left it there. I can use LTE just fine.
But returning the SIM to my S22, rebooting, and waiting 10 minutes; no signal again. I played with my Network Mode settings as the note 8 isn't 5G and was curious if that might be involved. Randomly my signal (and ability to text/call) returns if I set Network Mode to either 3G/2G (auto connect) OR 3G only OR 2G only.

This is some advanced shenanigans. In all my years with Samsung and Android, I've never had an update prevent normal operation of a phone. Hope this can help someone else, if they have the same issue.
