The theory may lend to the rumors that Apple will ditch the home button for the next version of the iPhone. This is exactly what we have already seen from Samsung with the Samsung Galaxy S8 and S8+. Each of these phones will skip the home button altogether in favor of on screen navigation buttons. The fingerprint scanner will move to the back. Users of the Galaxy S8 and S8+ will make use of an iris scanner similar to what was found on the Note 7 for quick and easy access to their phone.
A report from "DigiTimes" suggest that the iPhone 8 will include an iris scanner. This would allow users of the phone access to the home screen and apps without TouchID. This means that Apple could potentially ditch the home button. I wonder if they will curve the screen's edges as well?
