I recently bought this camera but today when I tried to take a selfie,it slipped through my hand.When I quickly picked it up,all the films started coming out one by one! I tried to stop it and lock the back film door or lid * but it wouldn't close.So I had to remove my films.But it still won't close.When I turned on the power button,the lens pops out like normal but my back film door won't close.So please tell me what should I do? Should I take it to Best Buy to fix it?
