iPhone display frozen?

Hello, my iPhone has a few cracks in it, but everything has always worked fine. This evening, the display simply stopped responding. Restarting doesn't help either (first press the volume up button, then the silent button, then the power button for a long time). Does anyone have any tips on how I can still save…

Is the touch screen good?
