Two iPhone 6; husband and wife both with broken screens.
Perfect no issues.
I have just started using iFixit, so far it has been a great experience and I am working on building my business.
The Touch ID function will only work with your phone's original home button assembly. This replacement part does not include the home button. You will need to transfer the button assembly from your old display to retain Touch ID.
I initially bought the package where you didn't have to transfer the mic, camera, and some other cables and this time bought the one you did ... not intentionally. I think the extra money for the full assembly is worth it as I took less time and was only ten dollars differe . . .
