iPhone XS A1920 (Verizon) Logic Board with Paired Face ID Sensors

Face ID sensors that are part of the earpiece speaker and front-facing camera assemblies are paired to the logic board in an iPhone XS. To retain Face ID functions a logic board must be replaced along with its paired components.

This logic board is "locked" to Verizon. If you wish to stay with your phone's original service provider you must replace the logic board with one locked to the same provider.
