When Apple unveils its new high-end iPhone on Sept. 12, it's widely expected to do away with the most iconic part of its handset: the home button. If the rumors are true, the all-screen design of the so-called iPhone 8 means no room for a bottom bezel, and thus no room for a physical home button (and its Touch ID fingerprint sensor). It will be the biggest design change to hit the iPhone in its 10-plus year history -- a radical change to the most basic usage element that has existed on the phone since day one.

A glyph that appears in the HomePod firmware could be the rumored iPhone 8.
