Recently, a couple of pictures leaked online claiming to be Apple iPhone 7's redesigned home button. It was said that the traditional home button (with fingerprint sensor) on iPhones has been changed to a capacitive touch key.
BUT, it is fake news. The leaked pictures are not of Apple iPhones, particularly iPhone 7. In actual, it is an upcoming android smartphone which adopted (copied) the same exact looking iPhone home button (See image below). It is dubious to pin point any particular android smartphone at this time. The leaked images confirmed that this so-called iPhone-like android smartphone is all set to be unveiled soon.
