This is a replacement Home Button Assembly (including Fingerprint Sensor) for the Apple iPhone 5S. This item has a Black (also referred to as Grey) Button.
This original replacement part for Apple iPhone 5S Home Button Assembly can support all the basic functions except for unlocking the iPhone using the Fingerprint Sensor.
Apple states that the fingerprint data is stored on the A7 chip in a Secure Enclave that is only accessible by the sensor itself. The Fingerprint/TouchID Sensor is tied to the unique logic board inside each iPhone. If you replace the original Fingerprint/TouchID Sensor then the iPhone 6S would need to be unlocked to access this data (which is not recommended and only undertaken by an expert).
This part is only for the Apple iPhone 5S. Please see out other listings for this part for other models of iPhone.
