After battling with dev centre downtime earlier on this week, Apple released the fourth beta of iOS 7 to developers last night.
iOS 7 beta 4 features a number of tweaks to the mobile operating system’s UI, an new API and some not-so-obvious code that could hint to a fingerprint sensor that’s rumoured to make it onto the iPhone 5S.
Discovered by Hamza Sood, iOS 7 beta 4 contains a new folder, named BiometricKitUI. Inside this folder are strings that describe a person, “holding an iPhone with their right hand while touching the Home button with their thumb,” as well as a confirmation message that “Recognition is complete”. It’s the first major hint beyond rumour and analyst notes that the next-generation iPhone will sport fingerprint sensing technology and although this doesn’t set the specs in stone, code appearing in iOS 7 beta suggests the new feature will be part of Apple’s next major iPhone refresh.
Elsewhere in iOS 7 beta 4; a few UI tweaks have been made to the lock screen to make the ‘slide to unlock’ function easier to use, the HDR toggle in the camera app has been placed in a more prominent position and a new API for detecting screenshots has been added – hopefully reinstating Snapchat’s screenshot notification. Beyond that, there’s also been some subtle updates to the gradients in icons and some changes to the size of buttons in the Phone app.
