Your iPhone could soon know when a thief snatches it from your hand

Apple is reportedly working on a new security feature called "AutoLock" for the upcoming iOS 27. The system aims to detect when a thief takes an iPhone from its owner’s hand and automatically locks the device to protect personal information. Although the feature is still under development and not yet available to users, recent code in the iOS 27.2 beta sheds light on how it might function.

AutoLock would consider several signals to distinguish between a genuine theft and everyday movement. These include sharp acceleration, sudden loss of connection with a paired Apple Watch, the Apple Watch remaining out of reach for an extended period, prolonged loss of network connectivity, and the iPhone staying unlocked for too long. The idea is that a combination of these unusual events could indicate that the phone has been snatched away from its owner.

If the system determines a possible theft, it could request that the iPhone locks automatically. To prevent false alarms, AutoLock would also include safeguards. For example, successful biometric authentication, familiarity with the device's location, and activity in certain apps could prevent an automatic lock. The system reportedly uses a voting mechanism, where signals indicating possible theft attempt to lock the device, while trusted signals can veto that decision, helping to avoid locking the phone unintentionally when the owner simply runs, drops it, or moves away from their Apple Watch.

However, it's important to note that Apple has not officially announced AutoLock. The feature is currently only present in the iOS 27.2 beta and is disabled by default. Apple may change, delay, or decide not to release the feature in the final public version of iOS 27. iPhones already have a theft protection feature called Stolen Device Protection, which adds additional safeguards when an iPhone is away from familiar locations like home or work.

This new AutoLock feature would address a different moment: the brief seconds after someone physically grabs an unlocked iPhone. Android already offers Theft Detection Lock, which automatically locks the screen based on on-device technology that recognizes movement associated with a stolen phone. Apple's approach appears to be aimed at stopping a thief from taking advantage of the short window when a stolen phone remains unlocked.

For now, iPhone owners cannot enable AutoLock, but the latest beta provides the clearest evidence yet that Apple is still developing this feature.
