After 15+ years, we've made a big change: Android Forums is now Early Bird Club. Learn more here.
Well this is an Android discussion site, so not the obvious place to ask about iPhones 
However, if shutting it down and restarting doesn't fix it (which I assume it doesn't) I suspect hardware damage, in which case repair will be your only option. Connect it to your computer and back it up, then talk to Apple. The only other thing I can think of is a hard reset (however you do that on an iPhone), which may be worth a try (but back up first), but my guess is that it will require a repair.
