Apple is working on a new security feature for iPhone that can automatically lock the device when it detects that it has been snatched from the user’s hand. The feature is designed to reduce risks in situations where a phone is stolen while still unlocked, giving attackers immediate access before security protections fully activate.
The details were reported by 9to5Mac, with Apple already offering protections such as Find My, Activation Lock, and Stolen Device Protection, but these systems are less effective when a device is taken while actively in use, as even with time-based delays for Apple ID changes, a thief may still access sensitive data in the brief window after theft.
How snatching detection works
The feature is designed to detect sudden theft-like motion and instantly lock the device using on-device sensors. It focuses on identifying movement patterns consistent with a grab-and-run situation.
The system is similar to theft detection features in Android, though Apple’s version is expected to rely more on ecosystem signals like Apple Watch pairing and trusted location awareness.
Key detection signals include:
- Sudden forceful movement while the iPhone is unlocked
- Motion patterns consistent with a snatching action
- Immediate displacement from the user’s hand
Once detected, the device automatically locks to block access to apps and data.
Context-based verification signals
To reduce false triggers, Apple is adding contextual checks using ecosystem and location data. These signals help confirm whether the movement is accidental or an actual theft event.
Supporting signals include:
- Distance from a paired Apple Watch
- Connection to familiar Wi-Fi networks
- Familiar locations such as home or workplace
- Trusted environment status
If multiple signals align, the system treats the event as a confirmed theft scenario and locks the device.
Integration with existing protections
The feature builds on Stolen Device Protection by adding real-time response during active theft situations. Along with locking the device, it may also restrict sensitive actions to prevent misuse.
Possible restrictions include:
- Blocking Apple ID and security setting changes
- Adding authentication delays for sensitive actions
- Restricting access to passwords and payment settings
Availability
There is no official release timeline yet. However, references found in internal system code suggest that the feature is actively under development.
