Will the replacement home button available in fix it work on my iPhone 7 and also will the touch id work?
NO, DO NOT REPLACE THE HOME BUTTON ON IPHONE 7. Touch ID is not repairable whatsoever on any iOS devices because the communication between the sensor and the CPU is encrypted with a unique key. Since iPhone 7, there is no mechanical switch under the home button, the pressing is sensed by force sensors under the button, the force data goes through the same encrypted link. Replacing the button will destroy both Touch ID and button pressing. So the replacement button is absolutely useless, you MUST send the phone back to Apple for repairs.
As a iPhone parts supplier, we would like to tell you the reality: The home button of iPhone 7 can NOT be replaced or changed. If you replace it, the new home button will be totally dead. New home button will NOT have returning to homepage function, let along the Touch ID / fingerprint sensor. Even if you buy 100pcs iPhone 7 new home button to try one by one. I can say all the 100pcs home button will Not work.
I have changed the home button for iphone 7 before 3 months and I tried for 5 home buttons and home button didn’t do the functions for it and not working at all. I have opinion for you, i think if u change the Taptic Engine under the battery the home button work, i will try this and tell u but the main problem I didn’t find the part i mean the Taptic Engine. Good luck Best wishes
@rajeshree Yes the home button will function however the Touch ID will not, just like the iPhone 5s-6s the home button is matched to the logic board. You put a new one on Touch ID is lost. Hope this helped
