The screen on my Sony Xperia Z is cracked. I have now sold the phone so I need to delete my text messages, can anyone help?
I can only press in certain areas of the screen so I can't click on factory reset or delete messages one by one.
The simple way to factory reset for unrooted phone is to perform a factory reset via pc companion.
I'm assuming that you can't factory reset it via the OS, so the best thing you can do is to boot into recovery mode. This is of course as long as you can see the options on the screen. So once in recovery mode, you can select the option to factory reset the entire phone, apart from your SD card that is.
Once you're in recovery mode, it should be pretty easy for you to navigate up or down, using the volume buttons. Select a preferred option by pressing the Power button.
Just look for the option to reset your phone.
