Why won’t the search for App not work on my iPhone?

I figured out how to cause this to occur!

I'm not 100% sure that it'll fix it for you, but worth a shot.

Try putting your phone to sleep/locking it.

Wake your phone but do not enter to your Home Screen.

Looks like you have a Touch ID model based on your screenshot, so the easiest way to do this may be to use a finger that is not set up for Touch ID to wake up your phone.

Once the phone is awake and waiting to be unlocked with Touch ID, swipe right. You should get to the Today View/search. My guess is that search is displayed and the cursor is captured.. Tap cancel so that you see your Today View widgets.

Now enter your phone and check if notification center/ search screen is back to normal.

Help us help you. What are your searching? The web? This site? Another site?

You’re amazing!!!! This worked like a charm! I didn’t have anything showing in my Search so I typed something and deleted it and it was completely solved! Thank you so very much!
