HomePod's firmware has revealed several new features coming to the upcoming iPhone, such as a tap to wake function, facial expression and attention detection, and virtual home button. "Apple accidentally released the firmware over the weekend resulting in a frenzy of analysis about previously unknown features," reports The Verge. From the report: Developers including Steve Troughton-Smith and Guilherme Rambo have been tweeting their findings, notably the discovery of the new iPhone's bezel-less screen design. They've also concluded that the resolution for the iPhone 8 could be as much of a visual leap forward from current-generation iPhones as the iPhone 4's Retina display was from the original iPhone. Apple is using codenames for both its face recognition feature and the bezel-less phone, called "Pearl ID" and "D22" respectively. A potential "attention detection" feature is also mentioned in the code, with some speculating that may mean the phone will remain silent for notifications if it knows you're looking at the screen already. Facial references such as "mouthstretch," "mouthsmile," and "mouthdimple" were also found, which are most likely a nod to Apple's rumored facial recognition feature that can even detect faces in the dark using infrared. A tap to wake feature has also been discovered, and should be similar to the Windows Phone function that allows users to double-tap the screen to wake the phone.
