Apple has introduced a new feature in iOS 11 that will let users disable their iPhone in the event of an emergency. 

When activated the Emergency SOS mode automatically calls the user's next of kin and temporarily stops Touch ID from working.

The system requires the iPhone owner to enter their passcode in order to revert back to normal, which could prevent thieves from taking advantage of an injured or unconscious person.

The mode is an option that appears when users tap the lock button five times in iOS 11, Apple's upcoming mobile software. It is an additional mode underneath "Slide to power off" that is also joined by Medical ID, which contains the health information for the owner. 

Apple is expected to release iOS 11 to the public after the launch of the iPhone 8 next month. The new operating system is expected to come with the iPhone 8, which tradition suggests will be unveiled on September 6. 

The best features of iOS 11, which is available in a trial beta form, include iPhone-to-iPhone Apple Pay that lets users send money to one another with a text message, and a redesigned control centre.

Built for the iPhone 8, iOS 11 also has new augmented reality features, including directions superimposed on the real world, and a smarter Siri. 

Another safety update is the new "Do not disturb while driving mode", which can detect when an owner is behind the wheel. It turns the iPhone screen black and stops calls and text messages. Users can set it to automatically reply with a note saying they are driving. 

Apple is planning a dramatic redesign of its flagship device in celebration of its 10th anniversary. The iPhone 8 is rumoured to have an edge-to-edge 5.8-inch screen and wireless charging. It could cost more than £1,000
