light turning off

[jesi]

Hi everyone I need help with my Xperia Z.. Everytime I dialed to call someone the lights of my phone is turning off.. I checked everything from power management settings to call settings and display setting but there was nothing that could help me solve this problem.. What should I do?

Is something covering the proximity sensor?

None.. I put a screen protector like a year ago and it has been working well until 2 days ago. If I pressed the call button the screen lights turns off. lights turn on if I press the power button though.

Can you check if the same occurs in safe mode?

I tried the safe mode test and the same problem occured..

Why did you accept my first answer as a solution? Did it help? I think you have a cover or a screen protector covering the sensor.

Sorry I must tapped it by mistake.. But I'm still having the same problem..

You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
