Apple is testing an iPhone security system that could automatically lock a device after detecting signs of a physical snatch. References in iOS 27.2 beta 2 describe an internal service called AutoLock, but the feature is disabled and Apple has not announced it.
Apple released iOS 27.2 beta 2, build 24B5089g, on September 21. Code found in the build indicates that AutoLock can combine motion, connectivity, authentication, and location signals before deciding whether an unlocked iPhone may have been taken from its owner.
How the proposed lock would decide
Potential theft signals include acceleration consistent with a sudden grab, losing contact with a paired Apple Watch, remaining offline for an extended period, and staying unlocked beyond a time limit. No single clue appears to guarantee a lock. The code instead describes a voting system in which risk signals request action and trusted signals can block it.

A successful biometric check, activity in certain foreground apps, or the phone being in a familiar place may prevent AutoLock from triggering. Those safeguards matter because an automatic lock that fires during ordinary exercise, a dropped connection, or travel could interrupt legitimate use.
The idea complements Stolen Device Protection, which adds biometric checks and security delays for sensitive account changes. Apple also began enabling that protection automatically in more managed-device situations earlier this year.
AutoLock is not exposed as a setting in beta 2. The underlying service is present, but the component that would perform an automatic lock remains switched off. Apple could change its triggers, postpone the feature, or remove it before a public release.
That makes this evidence of development, not confirmation of an iOS 27.2 feature. Users should continue relying on a strong passcode, Face ID or Touch ID, Find My, and the existing Stolen Device Protection controls rather than expecting an unannounced safeguard.
