The screen's top sensor assembly must move to a replacement to preserve Face ID and True Tone. Battery and USB-C guides use A2379 cellular hardware.
What to check before buying
Display sensors
iFixit describes the screen as the panel plus top sensor assembly. The original sensor assembly must transfer during screen replacement or Face ID and True Tone are lost.
Variant-specific guides
Battery and USB-C charging-port guides are based on A2379 Wi-Fi plus cellular/mmWave hardware. Wi-Fi-only tablets may require different disassembly, so the model number matters when using those procedures.
