I'm having network issues after the Android 12 update. Never happened before. I even used two SIMS (EE) (Vodafone) UK networks. Both disconnected at the same time and reconnect at the same time. This was purely a test to see it's definitely not a network issue.
Andriod 12 has caused my Samsung galaxy s21 ultra this major issue.
Cannot even call or receive SMS, basic functions of a phone.
Anyone got any suggestions or has had similar issues?
