Random problems and solutions for Windows phone users!
Problem: Random rebooting
A number of Windows Phone 8 users often complain about random rebooting of their phone. The issue seemed to be very common on the HTC 8X and Nokia Lumia 920 phones, although the problem didn’t affect every handset. These smartphones would just reboot without any warning. There are also some suggestions about this problem -
Microsoft investigated this problem and then released an OTA update in the North America in last December, commonly known as the ‘Portico,’ which fixed this random rebooting issue. To make sure that you have the latest update of the OS, just go to App list > Settings > Phone update > Check for updates and follow the prompts carefully.
Some users reported that the issue still persists, even after the update. But it’s always worth trying a restart. Press and simply hold the Power button and then slide down when you get to see Slide down to power off. Turn it on back again and see if the problem still repeats. Users can also try removing the battery and replacing it.
The final option is to try a whole factory reset. Make sure to get a backup first by going to App list > Settings > Backup and choose App list + settings and then Back up now. After that, go to About > Reset your phone and tap Yes and Yes again when prompted.
Problem 2: Auto-brightness bug
Some of the Windows Phone 8 users with the Nokia Lumia 920 handsets reported about fluctuating screen brightness problem. This problem occurs possibly due to the Portico update. It seems that a bug may have been introduced that impacts on the auto-brightness and causes the screen to flicker as it struggles to find the right brightness setting.
Users can disable auto-brightness and set the phone to Medium brightness just to prevent it from changing repeatedly.
Some of the users reported success or at least a reduced fluctuation of the problem by turning on the phone in a completely dark environment and then allowing the sensors to calibrate to the darkness.
