I have a problem with my devices Xperia Z3 Compact. When I restarted the phone, everything is good, but a couple second later, the screen is blackout and I can't touch anything in my phone. The only way to solved it by press and hold power button until popup power off show up. It always happen when I restart the phone. When I press n hold power button, I press "recent button" there are app called "Style Cover" always on top and this app that make my phone is black screen. I already do factory reset (to Android 6.0), but the issue is still exist. I try to turn off the Style Cover from Settings->apps->style cover, it doesn't work. Any suggestions for this issue.?
This application should only control the functionality in the device when you have a Style Cover attached and "installed", however there does not seem to be such a cover attached to your device.
Is there any change if you go to Settings > Apps > Style Cover > Storage > Clear data > OK? If there isn't, try performing a software repair using Xperia Companion and remember to backup your data as this reset will delete all data stored on the internal storage of the device.
