Best Choice: This new 821-00920-a Button with flex cable connects the power on/off to the logic board to replace a damaged or defective and not working Power Button that will make your device look better than ever.
^^ Product Description: That power button fingerprinting feature is disabled by default because Touch ID matches the logic board. This means that you can only use the power switch function, not Touch ID, please consider carefully before purchasing, thank you! ^^
