Why is my iPhone 6s not letting me type anything into the search bar?

I can start to type like 3 letters and then it'll go into a white screen then go back to my main home screen. So I can't search the Internet unless I click the actual safari app.

I don't know. Reboot and try again. If that doesn't work, go to Settings - General - Reset and then select "Reset All Settings".
