So, let me get this straight...
There were a subset of users BEFORE the update that were getting a ton of connectivity issues after the update to Android 12... I was one of those... I HATED it, but the best fix was the Airplane Mode since the Dialer fix out there killed any ability for me to connect to 5G and 4G LTE sucked for speeds (normally, it doesn't, but in this case, it did).
Then, the CVC5 update rolls out, and for me (and a lot that had the issue), it seems fixed. However, those that did NOT have the issues PRIOR to the update, now have the issue.
This is very Suspect as to their ability to support multiple variants of a device, even when the differences are very slight.
