Hi, I dropped my iPhone recently (It has a silicone case and a screen cover. There are no visible cracks on screen and no scratches but my iPhone has gone white. I can still hear sounds eg. Voice control but the screen remains white. I have tried turning it off via button but nothing happens. Please help and tell me what I can do and does it go away? Thanks
Added (1). This is much more strange as it now has changed to different coloured lines, I'm extremely worried now but it keeps changing from white to these different coloured lines.
