Apple is developing a new security feature that will automatically lock an iPhone if it is snatched from a user’s hand, building on its existing anti-theft measures to thwart tech thieves. The US tech giant has consistently rolled out upgrades to its smartphone security ecosystem, including remote tracking, distance-locking capabilities and strict anti-theft protocols designed to prevent criminals from changing Apple IDs or factory-resetting stolen devices.

The company is now turning its attention to a still vulnerable window: when a device is grabbed while actively in use. (continues below)

While Apple's current Stolen Device Protection offers robust security, it contains a significant loophole. If a thief snatches an unlocked iPhone straight out of a victim's hand while they are using it, the criminal gains immediate access to the active device. This vulnerability has prompted Apple to engineer a real-time solution.

According to technical details of the development, the new feature will rely on a combination of onboard hardware and ecosystem connectivity.
