A display where the touch screen is only partially working almost always indicates a damaged digitizer, requiring replacement of the screen; the damage may or may not be visible. Just went through pretty much the exact same issue with my grandson's iPhone X after a drop and ended up replacing the screen to fix the problem.

You have a few options with regard to replacing the screen. The simplest is to take it to an Apple repair center and have them do the job; that will guarantee you won't have any issues with non-genuine screen warnings, True Tone not working, or losing Face ID. The next best would be the Apple self-repair service where you buy the screen from Apple and use their equipment to do the repair yourself. Again, this will result in full capabilities for your phone and no non-genuine parts warnings.

''Note: Edited to remove references to the Apple Self-Repair program for this phone, as it does not qualify for the program. The oldest phone supported is the iPhone 12.''
A standard repair shop can also do the job, and if done properly your Face ID and True Tone will continue to work correctly, but you will get a pop-up on your phone for about a week warning you about a non-genuine screen - whether it is a genuine Apple screen or not.
If you decide to repair it yourself, that's great, but you'll need to take care with transferring the original Earpiece Speaker assembly over to the new screen; if it's damaged your Face ID will not work again. Also, in order for True Tone to work, a serial number has to be copied from the old screen to the replacement using a special device programmer; the iCopy device from the Qian Li company is one example. If True Tone isn't a concern, it will work fine otherwise without doing that programming.
With that all being said, here's the guide for doing it yourself.

You can support iFixit's repair efforts by purchasing a replacement screen from them; I'd recommend getting the Fix Kit option, as it includes all the tools and parts like adhesive needed to do the job.
Yeah, it's a bit pricey and to be honest you can find it cheaper in other places like eBay, Amazon or AliExpress, but it's up to you. Be sure to get a precut screen adhesive too so you can reseal it when you're done; to be honest, I usually buy a couple because they're easy to mess up and I don't like to have to wait to reorder if I make a mistake.
