SAMSUNG NOTE 10 + (SM-N975F) issues after OS Upgrade to Android 12 and UI 4

Network randomly disconnects both SIMs for 30 to 40 seconds Every now and then, both my SIMs will disconnect network, data and calls, VoLTE, 4G as well asinstead of network bars, just for a few seconds, then it goes back to normal. I have no idea what makes this happen, it happens completely at random, I can't really reproduce the issue at will. If I'm speaking to someone when it happens, the phone reboots.

I am having the same problem, called Samsung and they keep saying that I needed to send my phone away for repairs,  keep trying to tell them it was the up that is causing the problems but would not listen.  Told them about this form and that I was not the only one have the problem but they would not even look to see that they were other people with the same problem. Very disappointed with the service I received or didn't receive I should say.
