Hi everybody. I have a very strange problem and I hope someone can help me.
My problem is that the screen locks itself during app use or calls I make. When trying to open it, the screen locks immediately again. After couple of times it gets open, but it can take 2-3 minutes. I installed the phone again but the problem was the same. Then I tried to use a different sim and the problem stopped. I contacted my mobile service but they said they don’t see that there’s something wrong with it. Did someone heard of a problem like that? Can it be the sim or is it the system? What do you think I can do?
Thanks in advence.
