So I took pictures by pushing the lock button and home button on the Internet and after I took them I went to pictures and looked at them. So then I cropped them and suddenly the screen turned green, blue, and white. It stayed like that for a couple hours. And then it suddenly turned on so I kinda thought it was just a glitch so I went and cropped another picture and bam it does it again so I waited and then got back on and deleted the offending pictures. 
why does it work after I delete the offending pictures????
