Apple's iOS11 update provides the user with so much security that even the police can't get access to your phone.
The security feature lets you disable Touch ID so that only the user will be able to unlock the phone. The only alternative to this brings you to an SOS function by pressing the home button 5 times which will notify your emergency contacts of your location. Once the alert has been sent, only the owner of the phone can access the phone with their password and fingerprint.
The feature prevents someone (the police) from forcing you to open your phone. It also automatically contacts 911 in a case in which you are forced to open your phone or even just discretely dial 911 without being noticed. You are able to disable the automatic 911 call in the settings but it is definitely a great security feature in an unexpected event.
This is just the precursor for the introduction of facial recognition to unlock your phone. Phones will become more secure than ever.
