So, who Replaced the Screen?:

Is it YOU who replaced the screen? Or was it someone else?

Get a New Screen:

Your iPhone Screen has been installed incorrectly. So, if you did not perform he repair, then contact the persons who performs the repair. They need to fix this, on their end.

Getting a New iPhone Screen:

Contact Apple, and setup a Genius Bar Appointment or see an AASP (Apple Authorized Service Provider) in your local area. Be wary as to where you get this item, ask you may get an error of an ungenuine Mac screen. So, to avoid this continual message, it is best to have an Apple or an AASP replace the battery. So, where to get a new battery:

A. Apple Contact Info:

• Contact Us - Choose Locations
• Proceed from there, as necessary
• Why the Wait: Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :) 

B. Contact an AASP: 

1. Go Here: Find Locations - Apple Authorized Reseller
2. Click: Service & Support
3. Enter: your location information
4. See: if there is an AASP nearby
5. Contact: an AASP that shows up, and find out more about the services that they offer to fix the battery

Did you have your screen replaced by someone other than Apple or an actual Apple Authorized Service Provider? If you did, FaceID won't work again as only Apple or Apple Authorized Service Providers have access to authentic Apple parts. And if you had someone not authorized replace your screen Apple won't touch your phone moving forward. It is possible you can get Apple to agree to replace the screen on your iPhone, but you'd need to ask Apple if they will. They may. They may not. You should also have a notification that you have don't have authentic parts in your iPhone. Will make it impossible to trade the phone in and very difficult to sell it to someone.

If Apple Replaced the screen themselves, take it back to Apple. Otherwise, you'll have to live without FaceID now.
