Apple is set to launch iOS 11 in the coming weeks, and has already rolled out a beta version of the operating system.
Users on the beta version of iOS 11 have now noticed unannounced features, including an option to stop your fingerprint from unlocking your iPhone using Touch ID.
According to a report by The Verge, pressing the power button on an iPhone rapidly five times will bring up an emergency screen.
This allows a user to either call 911 services or enter a passcode to enable Touch ID.
“Until you enter that passcode, Touch ID won’t unlock your device,” stated the report.
“This appears to be an easy way to disable Touch ID… when you’re in a situation in which you may be forced to unlock your smartphone.”
The report follows news that US border control agents are searching thousands of smartphones and other mobile devices each month.
