My phone got ran over by a truck and then a car. AMAZING bUT

I dropped my phone (with speck case and full front camera glass and screen protection) while riding my motorcycle) and i saw it literally get ran over by a Ford F-150 and a Honda Accord. and amazingly sufferred no visible damage besides shatterred screen and camera protector glass. The screen initially still functioned fine and the phone still functions fine but the screen is now black-- its not cracked or broken anywhere but I don't know wby the screen no longer gives off any light.
