So I had the s21 for less than a month and recently the phone frozed, crashed and was stuck on a boot-loop for a long time. Until I decided to factory reset the phone. After that happened, I reinstalled from my backup. The problem now is that for the past few days the phone keeps on freezing and crashing leading to a short reboot on any app. I put the phone into safe mode. But guess what it frozed, crashed and rebooted out of safe mode. So I don't know what do now. Hoping to to get a replacement from Samsung after I talk to customer service tomorrow.
S21 5g unlocked (no carrier)
Back from the tech service and they claimed they didn't encounter any problems. But the second I got my phone back. It froze, crashed and rebooted. Problem still exist
