- Check if the battery does not move! If it does:
FP2 restarts when it is hit at one of the front corners
- disassable your phone and check if all the screws are tighten. I noticed that som contacts are not tighten enough. It caused in my case that sometimes that people died not hear me and caused charching problems. Realy check every contact and screw. I think that you will also have a contact problem at your battery or somwe where else.
