I recently received my phone back from Sony after a issue with a busted screen. Sony took it upon themselves to install a new OS to my phone which looks pretty good. Worked.fine for about three weeks. Now whenever I lock my phone using the lock screen button it's locks and turns the screen off. Standard. The problems comes when trying to wake it up. I'll press the lock screen and have to wait 4-5 seconds before the screen lights up. If I press it again before that it puts it back into sleep mode. Only way I get an immediate wake up is when I let it go to sleep on its own then wake it up. Is there a correction for this or is this a problem linked to the new OS.
