I returned the phone and bought a similar z2 from Orange Romania . The the firmware build on this one is .69 personalized for Orange Romania and I still have the same problem , the phone reboots during some calls.
I couldn't find other people with the same issue and that seems strange since the 2 phones are totally different batch.
Can anyone give some clues on this isuee?
1. Factory reset > if problem remains then do this;
2. Repair Firmware via PC Companion. > If problem remains do this;
3. Flash another stock firmware by Flash tool
after all u can ask for warranty service
However if u like custom roms u can unlock phone and flash this mod;
