Iphone 4s, when in camera/video menu the image it's shaking and colors from the screen changes to something like windows error 256k colors sometimes after i whipe to unlock it the screen goes black or white, or from normal colors it goes to strange colors. They will reset tough if i lock it, all these symptons are randomly, also when in home menu 1 or 2 application from the left side has their text shredded from the far left side of the screen. If i`m on the message screen everything works, no strange shreds or tears, no color changing, no white/black screen.
