In iOS 11, Apple has added an "Emergency SOS" feature that's designed to give users a quick and easy way to summon emergency services should the need arise. As it turns out, there's a secondary benefit to Emergency SOS - it's also a way to quickly and discreetly disable Touch ID.

Emergency SOS is activated by pressing on the sleep/wake button of an iPhone five times in rapid succession. When the requisite number of presses is complete, it brings up a screen that offers buttons to power off the iPhone, bring up your Medical ID (if filled out) and make an emergency 911 call.

Along with these options, there's also a cancel button. If you hit the sleep/wake button five times and then hit cancel, it disables Touch ID and requires a passcode before Touch ID can be re-enabled. Touch ID is also disabled if you actually make an emergency call.

This is a handy hidden feature because it allows Touch ID to be disabled discreetly in situations where someone might be able to force a phone to be unlocked with a fingerprint, such as a robbery or an arrest. With Touch ID disabled in this way, there is no way to physically unlock an iPhone with a finger without the device's passcode.

It's also worth noting that there's no real way to tell that Touch ID has been disabled in this manner. Once you hit the sleep/wake button and then tap cancel, it's locked in the same way and with the same message that the iPhone uses when it's been more than 48 hours since a device was last unlocked with a fingerprint.

Apple's Emergency SOS feature will be available on all iPhones that run iOS 11. Along with disabling Touch ID, SOS can also be used to summon emergency services and alert your emergency contacts when an accident occurs.

iOS 11 is available to developers and public beta testers at the current time and will be released to the public in September alongside new iPhones.

ZERO people will recall this feature exists, or how to activate it, when a situation arises. Utterly convoluted.

When you factor in adrenaline in emergency situations, you're are correct. Blood flow is directed away from brain and recirculated to the large muscle masses, which makes it very difficult to make quick decisions and it affects memory retention. This feature is something would have to remember or at least be familiar with in the least. Although Better to have this SOS feature than not at all. I like Apple's thinking here.
 
This is a great idea, but why pressing 5 times?
Surely 3 times would have been more than sufficient while making this action quicker and ultimately more usable.

3 taps is already an established function (reverse color) in iOS. Also, I accidentally do that function all the time when trying to do a double-tap, so it's a bad idea for emergencies.
 
makes no sense having to press cancel... it defeats the purpose of emergency and discretely because you have to pull the phone to do it and advertise it at the same time... when you get robbed you don't pull your phone in front of the robbers... Cancel should not be required so you can do it in your pocket DISCRETELY.... ! why such complication ? at least make it a user option

I don't understand the benefit of changing it from TouchID to PIN when getting mugged. If the robber is there to compel you to use your fingerprint to unlock it then they can just as easily compel you to unlock it with your PIN.

I'm guessing you don't actually have to push cancel. The phone will probably go back to sleep after a few seconds if you don't do anything, at which point that would count as a cancel and the fingerprint sensor should be disabled. You can do that while it's still in your pocket.
 
If you ever fidget with your phone while waiting and press the power button on and off, then 5 times is a good idea. At 3 or 4 you remember that the alarm will go off if you keep pressing.

Yes but if they shoot you they still won’t be able to use the device. And you could always claim ignorance, the phone isn’t yours etc.

The article says you have to push it so I hope you guessed right

Phone does not go back to sleep actually. Stays lit up and will not lock even when pressing the lock button. Pressing the home button also does nothing once this is activated.

Because you're more likely to do that by mistake? Especially older folks.
