I foolishly dropped my iPhone 7 last night. The screen protector shattered but the screen itself is still perfect.
The screen lit up but had some lines across it, I then switched it off and have no been able to switch it back on since, even trying a reboot etc.

There are no notification sounds and if I call the number, I get a ringtone from the phone that I am calling but the iPhone 7 does not physically ring.
Also, the home button seems to be working ie. it can be pushed in telling me that the phone is "on" somehow.
iTunes recognizes the phone but I cannot do a restore as Find My iPhone is on.

I have managed to grab all of my pics off the phone so I have no issue with it being wiped.

Any ideas on whether this is a software or hardware issue?
The phone is 3 months old.
