Although the iPhone xr face is not completed through the handset, but the handset and those sensitive originals are together, but there are a lot of original components, because the screen assembly is not with the handset, the handset is a separate module in the iphone, changing the handset and the screen is irrelevant, so after changing the handset, remember to install the chip on the line. It doesn't affect the face.
In addition, the face unlock has nothing to do with the handset, and the face unlock is mainly identified by the camera. So it doesn't matter if you change the receiver.
