Screen locks or notifications come on when talking on the phone

[dimitrism]

Since I upgraded to v5, the Phone functions improperly.
When talking on the phone and try to hang up I sometimes find the screen locked or the notifications screen is on making it almost impossible to use the phone application

@dimitrism

does your phone has a protective case and/or film? does it has an smartkey app?

[dimitrism]

No, it doesn't

Could you elaborate a bit more on the notifications issue?

Do you experience the same while on safe mode?

Hi

I have a same problem when call notification bar slide down and must slide up to reject call

When start in save mode , can I change a sensitiivyti of notification bar?

Problem still persists.
The only thing I think I should let you know about is that I have vpn adjusted to connect to my office, so as far as I know android automatically and by default activates the screen lock

I am testing it in safe mode and so far i don't have any problem.

@dimitrism

Which means it's a third party app creating this problem.

Which one?
Sony's live wallpaper or screen lock.
No other application has control over the screen
