1) Proximity sensor problems
When I answer a phone call the screen just doesn't go off. The same if I make a phone call. This is pretty annoying because during phone calls I often touch buttons with my face and I mess up with settings.
2) Notification LED stuck
Sometimes, let's say about once every two weeks, the notification LED keeps flashing even after I wake my phone and read the notification. The only way to reset it is to do a hard reboot.
Do you have these problems too? How could I resolve?
