My mother's XSP have some problem after updating to 4.3
Like before, there wasn't a single problem with screen when she was on 4.1, after updating it to 4.3 and screen can turn it off by itself without notification. Just turn off and that's all. She have to wait few seconds in order to make XSP respond to power button and turn on the screen.
Mostly this happen when using Facebook App, yes she's using Xperia with Facebook and Facebook messenger.
Apps are up to date, I've already try factory reset aka wipe data. Still problem occurs.
Anyone with the same problem or an idea how to fix it ?
Like I'm having same set up on my XL with 4.2.2 and no problem.
I don't know if that will help buyt she's using stock 4.3, her model is C5303 and her customization number is: 1273-0060.
Yes she have branded phone.
