The camera on my phone is getting weird lately. Sometimes it stops working, it flashes and goes right back to the homescreen. I can only get it to work again after restarting the phone. This only happens once in a while but it's kinda annoying. my sis has the same phone and she never has this prob. And I have a bunch of apps running in the background too, like Viber, facebook, tumblr, instagram, etc. Wonder if that has anything to do with this. Any idea?
