Help Lock Glitch?

[Note 2]

I think I found an odd glitch with my note 2.... is there anyway to fix this annoying problem?

I have my lock time set to 30 minutes cause I hate unlocking it every time I pick it up but I want it to lock eventually if I ever lose my phone so the 30 min works pretty good for me. BUT here's the odd thing, if I am on the phone even for one minute and after the call ends my phone automatically locks and I have to enter my code to access anything again. Am I missing a setting somewhere?

Thx all in advance.

EDIT: Thought I would add everything is stock.

Are you pressing the power key at all? Your current settings may be to enable lock on power key - so it'd lock regardless of delay.

Good thought but I did disable that. It still locks after any phone call I get disconnected from or hang up on?

Can anyone else mimic this problem?

Another thought then... is your screen off and then you receive a phone call? You can answer calls without having to unlock. So then, after your call, you'd need to proceed to unlock as usual. I know that scenerio for sure.
