screen doesn't lock automatically

[tjs]

I have xperia z2, updated with software build number 17.1.2.A.0.314
My screen doesnt lock autimatically ... I have to always lock it manually by pressing power button
In settings i set display-> sleep -> 15 seconds
And security -> automatically lock -> immediately after sleep

It's very annoying and i lose battery faster
Any help
Thank.you

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.

Have you checked what the Sleep settings are: Main Menu > Settings > Display > Sleep?

Or have you enabled Smart Backlight control?? If that's enabled, the phone will not lock itself when you are looking at it!!!
