Hi, got my phone in October.
I had the issue of the phone being in a "boot loop". Used online chat to fix. Sadly had to do a complete factory reset.
It then had the same issue 3 more times. I sent phone off to be repaired.it came back with a clean bill of health and no issues were detected.
I have had it back for 3 days and it has done the same again. Samsung say they can only repair it.
Has anyone else had any similar problems?
