Hi,anyone have this issue in the moment when start ringing on the other side,screen goes black i can wake it up only by double pressing the camera key,i read that this is common issue with xz2 phones someone has report that changing the stock dialer is making this problem goes away but not in my case,i check sensors in diagnostic menu phone says diagnostic is ok,im not using any screen protectors or covers and nothing is covering the sensors,i did full factory reset and having the same problem again,i dont have a warranty on it so any susggestion would be great.
