HI, I am a Sony Z5 Dual-user, recently my phone showing one problem on screen. When the calls are coming to the phone, it will ring but the display will switch-on, recently the same problem is showing while unlocking and restarting the phone. But sometimes it will perfectly. there are no damages or cracks in the screen and the battery also not jumping. sometimes the screen will switch-on while connecting the charges. Any idea what the problem is this?
