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

[JayeshK11]

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.

Hello Tech Tem Any update on this

[j-p]

Same exact model, started happening right after the upgrade, same exact issue. Sickening that there are no more responses from Samsung on this from one of their flagship models. Can't use the phone for this long so now we're are having to look at buying another phone. Can you guess what brand it won't be...
