Q: dropped phone. will turn on to main screen but wont let me swipe or enter passcode. help please?

Hi swipeless,

Thanks for using the Apple Support Communities!

I understand that after a drop, your daughter’s iPhone is no longer responding to touch on the display. 

In this situation, I would first recommend some basic troubleshooting to see if we can get the touchscreen to respond. The following article will walk you through these steps.

If the issue remains unresolved, it may be necessary to have the iPhone evaluated for service by an Apple Retail Store or Apple Authorized Service Provider. 

The following link explains these options as well as provides links to contact us or an Apple Authorized Service provider if you choose to go this route.
