Help Why is my screen is not locking?

[Anndroide]

Hi I am using a new Samsung III Advance which was working perfectly but now I am seeing that my screen is no longer locking after the phone stands idle. I have gone through all the settings and I cannot find any logical explanation...use visible pattern and timeout are both selected. ANY SUGGESTIONS PLS!

Have you checked any background apps that could be stopping you from locking the screen? Try using a task manager to close all apps.
If all fails let the battery run out then reboot.

Ive had the same issue several times, rebooting the phone indeed solves the problem.
