Xperia U: Forgot the screen PIN
I am using Xperia U and when i was checking McAfee security, I accidentally switched the screen lock on my phone.
Because I do not remember setting the PIN for unlocking my phone screen and now I can not use the phone!! I've tried all the combinations that I would have put but nothing worked.
Does anyone know how to unlock it or do I need to reset or install software or something!?
Can you please please teach me!!
