> On the iPhone if you tap power five times or hold power and volume up or down for a couple of seconds it disables face/touchid until you enter the passcode.

It should be noted that those two methods are not equivalent.

The "tap 5 times" methods starts a countdown to call emergency services, which you will need to cancel if you are just trying to temporarily disable biometrics. It can sometimes be a bit difficult to cancel that call.

Once when I used "5 taps" it opened Apple Pay after 2 taps (which is normal), opened the emergency screen and started the countdown after 5, and then switched back to the Apple Pay screen. I managed to get back to the emergency screen in time to cancel the countdown.

A couple other times when I've clicking cancel on the emergency screen it has turned on the flashlight.

The "hold power and a volume button" on the other hand brings up the emergency screen but down NOT start the countdown. If you keep holding the buttons for a few more seconds it will start the countdown. The phone vibrates when it brings up the emergency screen so it is pretty easy to wait for that and release the buttons so you don't start the countdown.

Also note that you can disable starting the countdown on 5 taps and/or on long power/volume hole in the Emergency SOS settings. 5 taps and long power/volume still bring up the emergency screen and still temporarily disable biometrics.
