I do not know if anyone else has this problem.
To me it has been starting for a week or two the phone to restart, it asks me the pin every two or three days. He says it's for safety but I have not done anything to do this "for safety."
Always insert the card unlock pin and the unlock screen pin. It is this second pin that gives me problems. I put my code and it does not unlock the phone. He keeps the numbers on as if he had to put more information. There is no accept button or anything. I leave it and it becomes blocked, I put the code back and the same thing happens ... in the end I blocked the phone.
I've already turned it off, rebooted, removed the card ... everything. The problem is with the telephone.
Did the same thing happen to someone? Can you help me?
Thank you very much
