can i replace my home button and still have touch id functionality?
I have an iPhone 6s Plus and would like to replace the home button along with the screen. Can I do this and still have Touch ID functionality.
Apple will only replace the screen and battery. Other issues would be dealt with by an out-of-warranty unit which would provide you Touch ID functionality.

If you use a third party vendor it would be at your own risk.
