Just looking to retain home button function, I am not concerned about retaining Touch ID. If it can’t this is going to push along of schools into paying for apple care.
Replacing the Home Button will not retain the TouchID functions but it will allow you to “push to click”. If you want to change the HB yourself, check out this guide.
Nathan, On the iPad 6 if you replace the home button it will continue to work as a home button without Touch ID. The issue regarding the iPhone 7/8 was due to it being a solid state button, while the iPad 6 button actually physically moves. I hope this helps, Charlie B. Source: 2 Years experience
Do you mean after screen replacement with original home button still Touch ID will not work ?
