My S21 has restarted randomly about 5 times over the past few days. I've noticed in the past that when I would pick it up it would be in the password screen, like it was just booting up, but I just ignored it. Lately it has been freezing up when I was actively using it. I also noticed that the freeze/restarts are not tracked in the "Restart History" in Device Care.
This seems to be a common problem/ known issue with S21's, but with no fix except to factory reset (which is very inconvenient).
Is an acceptable resolution being worked on by Samsung?
