Good morning,
so I have had my Sony Xperia Z3 for one and half year, since then it was repaired 3 times, 2 times they gave me new motherboard and last time they said everything is working fine. The problem is that if I turn my screen off, the whole phone goes off, sometimes it restarts by itself and sometimes I have to do it manualy by pressing and holding power button with volume up & down. This happens every 3 minutes If the phone isnt connected to USB and charging. Obviously it is software bug, which I, neither authorized service center, cant repair, tried factory reset and software repair via PC. 159 restarts from 3 a.m. until 8 a.m. Sorry for bad English.
Thanks in advise.
