iOS 15, the new version of the iPhone operating system, has already been officially released. All those models with iOS 14 will be able to update and receive many of the news announced at the last WWDC. The new update also brings with it important changes at the security level. One of them is related to Face ID and affects the iPhone X and later models, as well as the iPad Pro.
Specifically, Apple has improved facial recognition technology in iOS 15 to avoid a vulnerability discovered in previous versions, as detailed by the company on its website (via MacRumors). The security flaw could allow unlocking an iPhone or iPad Pro through Face ID using a 3D model similar to the owner’s face.
The affected models are those with a TrueDepth camera, which in turn, houses the sensors for biometric unlocking. The enhancements will therefore be available on iPhone X, iPhone Xs, iPhone Xr, iPhone 11 and 11 Pro, iPhone 12 and 12 Pro, iPhone 13 and 13 Pro, and on all iPad Pro models with Face ID.
In parallel, the new update of iOS 15 and iPadOS 15 also includes fixes to different vulnerabilities found on devices. Among them, a bug in the Neural Engine that allowed arbitrary code to be activated with system privileges on devices with the aforementioned chip.
iOS 15 is now available for iPhone 6s and later
As it is a security update, it is important to install it as soon as possible. Users with an old iPhone or those owners who do not want to update to iOS 15 at the moment, can receive the security update without having to install the new version of the operating system. Face ID enhancements, however, appear to be available only on iOS 15. Upgrading is possible via Settings > general > Upgrade from software.
iOS 15, remember, includes important changes and new functions that will allow you to get the most out of Apple’s operating system. The novelties of FaceTime, the redesign of Safari or the Live Text function are some of the new features that are coming with this version. The company will also activate other features in future updates. Among them, the possibility of using spatial audio with dynamic head tracking or ‘Universal Control’, to use the iPad and the Mac simultaneously.
