Help Screen Lock keeps turning itself off

[kevmars]

Hi All

This has only happened a couple of times but when it does it is annoying. I can pull my phone out of my pocket, press the power button on the top to turn it on and the phone is already unlocked (no lock screen). I turn it off, leave it a few seconds then turn it back on and it works? I s anybody else having this problem or is it the phone that needs replacing? Any help much appreciated

I would check if it is only during certain apps that this happens with. Certain apps can stop the device from normal handling, so try to keep track. Just like certain apps like navigation wont allow the screen to shut down.
