Apple appears to be moving ahead with an iPhone feature that could lock the screen automatically when the device detects a possible snatch theft. Fresh references in iOS 27.2 beta 2 describe a more detailed system than the early clues found this year, although Apple has not announced the feature or made it available to testers.
Apple released iOS 27.2 beta 2, build 24B5089g, on September 21. Code in that build refers to the feature internally as AutoLock and indicates that Apple is testing several signals rather than relying on one abrupt movement. That matters because a single accelerometer trigger could lock a phone during ordinary exercise, travel, or a dropped device.
How the reported AutoLock system works
The new references point to sharp acceleration, an unreachable paired Apple Watch, a prolonged loss of network service, and an iPhone remaining unlocked beyond a set interval. The apparent design uses those signals as votes for locking the phone. Biometrics, a familiar location, or normal activity in certain foreground apps could veto that request and reduce false alarms.

That is a different job from Stolen Device Protection, which adds stronger authentication and security delays after a thief has the phone and may know its passcode. AutoLock would try to close the brief window while a stolen iPhone is still unlocked. Our earlier look at the first AutoLock evidence covered the broader concept, while the beta 2 code adds the clearest picture yet of how Apple may judge a theft event.
It is not active yet
The underlying service appears to run in the beta, but the component that would actually lock the screen remains disabled. There is no user-facing switch, supported-device list, or promised release date. Apple could change the logic, delay it, or remove it before the public iOS 27.2 release.
Beta users therefore should not treat AutoLock as protection today. They can still use Find My, a strong passcode, and Stolen Device Protection, while remembering that other iOS 27.2 discoveries are also unfinished code rather than shipping promises.
