Hello,
three days ago I have received the update to Android 12 on my Galaxy S21 5G and, since then, the phone is almost unusable to make phone calls
Both sims reset themselves periodically, within minutes, dropping the network and any phone call in progress.
After trying to reset the network settings, the phone has started to request the pin for the sims at each reset, so I had to disable it. Keeping one or the other sim active only isn't changing the behaviour.
The diagnostic on the phone doesn't detect any issue even if run while the network is down.
Does anyone incurred in the same issue or found any solution? The phone is 3 months old...
