so i just bought Lumia 1520 in December and i guess i've never really pay attention or try out the dedicated camera button until recently. the thing is the camera button doesnt take pictures when i pressed it. it however did flash the LED but only that. when i pressed the button it doesnt open up the Camera app too. i've tried looking for setting but i have found none. so i was wondering if there's setting somewhere that i haven't enable or the button really does not work...? or maybe i wasn't using it right..?
