9. Border crossing mode
If you’re around people you don’t trust or crossing a border, you might want to disable Face ID altogether. By pressing the sleep/wake button five times, you enable emergency mode.
This iOS feature disables Face ID so that nobody can force you to unlock your phone — you’ll have to type your passcode. It’s also a good way to quickly dial emergency services and access your medical ID.
10. Hey Siri, where are you?
You can still access Apple Pay when your iPhone is locked. You just need to double-press the sleep/wake button on the side of the device to launch the Wallet app.
But what about Siri? You can’t trigger Siri by holding the home button anymore. Instead, you now have to press and hold the sleep/wake button on the side of the device.
