In the absence of a physical Home button, Apple's so-called "iPhone 8" may allow users to activate Siri by holding down the Sleep/Wake button if they prefer not to do so using the voice command "Hey Siri". That's according to iOS developer Guilherme Rambo, based on a discovery he has made in source code that points to the possibility. In a tweet posted on Saturday, Rambo said he wondered if Apple had moved any of the original Home button's functionality to the "lock" button (or Sleep/Wake, as Apple calls it) located on the upper right side of the handset. When asked by a follower if he had found something in Apple's code to suggest this, Rambo revealed that he had indeed discovered a gesture to invoke Siri by holding the lock button. Apple's radically redesigned iPhone does away with the Home button entirely, relying instead on a new gestural interface that includes a "software bar" along the bottom of the screen and an app dock similar to the one found in iOS 11 on iPad. While next-generation facial recognition technology is said to replace Touch ID fingerprint authentication, details are murky as to how Apple plans to remap other functions that traditionally involve pressing the Home button. For instance, any method of invoking Siri using the Sleep/Wake button would need to be sufficiently distinct from the current long press that activates the slide-to-power-off screen, unless Apple has also relocated the latter function. Another possibility is that the power button on the OLED iPhone houses two separate contact switches, which could explain why it appears elongated in some alleged design leaks.So lets see if siri gets anymore annoying.
