IPhone stopped working

[Knucklehead545]

My friend dropped her phone on the concrete face down and the screen didn't crack but the screen has lines and bars on it and is unusable
P.S. is an iPhone 6+s

Digitizer is likely broken, if it isn't responding to touch. That means you'll need to replace the screen, since the two are probably fused together.
