Hello i my phone has problems coming back from sleep. When i lock my phone or it falls screensaving mode, it wont come back to use when i click right side power button... its about 50/50 changes to wake up. It goes every time to lock when i press power after using, but not come back from lock. :/ If the problem comes i have to hold power to wake up the phone, then its show do you want to use plane mode or turn off the phone... Is this problem to solve my self or do i have to bring this back to store? Tried to load battery full, but doesnt make difference. Screen is black after i lock it... This problem came yesterday. Thanks for answeres!
It seems it is a software. 1. Try to boot your phone in safe mode to see if the problem caused by some app you installed before. 2.Download Xperia Diagnostics from Google Play, and run tests on your phone. 3.There may be a bug in your system. Update your phone.
