I have a Samsung digicam L100. It is only 2 months old. My friend was taking pictures with it earlier but for some reason, it wouldn't turn off anymore... I'm really desperate to get it going as I am on holiday and really need the camera What can i do? It wouldn't turn off and none of the buttons work no matter how much I press them repeatedly. It looks like it's stuck or something. How can I reset it???

pop the battery out and pop it back in. This will force it off and maybe that will reset itself. My camera when it was new had some quirks but after happening one time or two it never did it anymore.
