Sorry to hear that you have issues with your Z2.

If this issue remains even after you perform a repair of the phones software using PC Companion (or Flash tool if you unlocked the booloader) i'm afraid it sounds like a hardware issue. For more information about how to submit your phone for repair and where, contact your local support team.
