Hi @Members_MLTMMG. Do you have a case or a cover on your phone? Please remove the SIM card and give the contacts a rub then reinsert it. Also, please test your phone in Safe Mode. To do this, hold the 'Power/Bixby' button and the 'Volume Down' button, both together for a few seconds and then long press on Power off on the screen. This will change to Safe Mode so tap on that to restart. This will disable third party apps and if your phone is fine during this, indicates that an app may be causing the issue and I recommend deleting apps one by one until you find the culprit. Let me know how you get on.

Have the same issue EE sim had a Engineer look at the unit S21U said phone passed diagnostics then told me putting in a 5g sim will sort the problem.
Well the sim has been working fine for 8 months in the unit until the android 12 update.
