Apple is developing a new iPhone security feature that could automatically lock your phone when it detects that someone has snatched it from your hand.
Initial code references surfaced earlier this year, pointing to an anti-snatching system Apple was quietly developing. New code in iOS 27.2 beta 2 now reveals considerably more about how it could work.
Internally called AutoLock, the system doesn’t rely on a single movement or sensor to decide that your iPhone has been stolen. Instead, it weighs several signals before deciding whether the screen should lock.
Your iPhone would look for several warning signs
A sudden acceleration consistent with the phone being pulled from your hand is one of the signals AutoLock can detect.
The system can also take into account whether your iPhone suddenly loses its connection to a paired Apple Watch, remains without a network connection for an unusual amount of time, or has been sitting unlocked longer than expected.
Rather than allowing any one of those events to immediately lock the phone, AutoLock uses what the code describes as a voting system. Different signals can request a lock, while other information can stop one from happening.
A successful Face ID or Touch ID authentication can override a lock request, for example. Being in a recognized location or using certain apps in the foreground can also tell the system that the phone is probably still in its owner’s hands.
Apple has even built in a backoff mechanism to prevent repeated lockouts if the system encounters several false triggers within a short period.
Apple is already testing the detection system
The underlying AutoLock service is enabled in iOS 27.2 beta 2, but the component responsible for actually locking the screen remains disabled.
That means Apple can test how frequently the system detects potential theft and how its safeguards respond without unexpectedly locking developers out of their iPhones.
There’s no AutoLock switch in Settings, and nothing in the current beta allows users to turn the feature on themselves.
If Apple eventually enables it, AutoLock could close an important window after an iPhone is stolen. A thief who grabs a phone while it’s already unlocked may have access to personal information and sensitive apps before the owner has time to activate Lost Mode or remotely secure it.
Automatically locking the screen within that window would force the thief back through the iPhone’s authentication protections without requiring the owner to do anything first.
Apple hasn’t announced AutoLock or said when it could become available. For now, iOS 27.2 beta 2 shows that the detection system is actively being tested while the part that would actually lock the iPhone remains switched off.
