I have a Samsung Galaxy S3 with Jelly Bean. I would like, for, my screen to lock if proximity sensor is covered (for instance, when it is in my pocket).

How can I do that?

I am searching for an app as I have not found anything within the standard menu.

Does the proximity sensor (assuming NFC) work on pockets? I thought it only worked with other NFC capable objects. – CatShoes Jan 8 '13 at 19:29

Have a look at Smart Cover, Cover Lock, Simple Cover Lock [Beta] and others on Google Play. You can probably find other apps that maybe are better for you by just looking at the 'similar' apps section on Google Play.

Simple Cover Lock [Beta] does the job. And it's free. – Mariano Jan 8 '13 at 19:49
