Rumours are already abuzz that Apple will eliminate the physical home button for good by integrating it under the glass screen when it launches the next iPhone in 2017.
That being said, it appears as if all is not well with the solid-state home button on the iPhone 7 and 7 Plus. Recently, an image was posted on the MacRumors forum which read "The Home Button May Need Service. In the meantime, you can use the onscreen Home button below."
This virtual home button discovered by a layman on the MacRumour forum is not entirely new and has been there with us for a long time now. Known as the Assistive Touch, the virtual button serves the same purpose as the physical home button along with a few shortcuts which include one-tap access to Notification Center, Siri, Control Center, and a few more.
Earlier, the Assistive Touch feature on the iPhone had to be enabled manually. However, with the iOS 10 rolled out, Apple is providing this feature by default whenever there is a Home button malfunction or when it needs service.
With that being said, if you want to give the virtual alternative for the home button a try anyway, follow the below instructions.
Open Settings > General > Accessibility and scroll down until you find Assistive Touch and enable it. Voila! You can now use it to access Siri, open notifications, take a screenshot, control the volume, and much more just by a few taps.
Do make a note that, unlike the physical home button, the virtual alternative doesn't support fingerprint recognition.
