Xperia Z won't unlock

[RiozNewbie]

Hey guys again when my phone stays locked for a long time it won't unlock at all and I have to force reset with the power and volume button... Why is this?

The screen/phone doesn't unlock when you swipe to unlock it? 

settings > about phone > diagnostics > test the screen.

Do you have any antivirus? taskillers? third party home launcher ? third party lock screen? any protective case ? 

you can also boot on safe mode > try to recreate the issue

if you can't recreate the issue while on safe mode then it's a third party app that's causing this issue.

No the screen is fine. It only does it if it's locked over night normally and none have no anti virus or anything like that

I think it's an app acting up, it'll be wise to boot on safe mode overnight and see if you experience the same issue, or, repair the phone with PCC
