iPhone 6 Home Button Repair. When an iPhone 6 is dropped it isn’t always just the screen that breaks. In this case it was also the home button! We had to replace both the screen and the home button during this repair. The unfortunate thing about the iPhone 6 home button is that once replaced the finger print sensor no longer works. Apple ties the finger print sensor (built into the home button) to the logic board in the phone. This means that if you change the home button hardware the sensor no longer functions.
