Developer Guilherme Rambo, who has already unearthed details about the “iPhone 8” and other coming Apple products like the HomePod and a 4K Apple TV, claims to have found a “gesture to invoke Siri by holding the lock button.” 9to5Mac and MacRumors both reported on the discovery. >Apple’s preferred way for users to interact with Siri will almost certainly remain voice and the “Hey Siri” callphrase. But having a reliable, consistent way of pulling up the iPhone’s digital assistant without speaking to your phone is important — both as a backup and for consumers who are simply more familiar with holding a button to access Siri.
