Dear all 

My s21 ultra 5 G is disconnecting constantly and not getting proper signal for both Sim card since I update the software 

Did any one had the same issue ?

Thanks

Yes and I contact with Samsung care they said it's probably issue with android 12 !!

I faced the same problem. I went to Samsung maintenance and they said we don't know what the problem is, so they changed the motherboard, and the device now has no problem.

Thanks ,means they open the phone and change the main circuit inside 🤔
