This horror scenario is familiar to many: One moment you are looking at your iPhone screen, and the next moment you are left empty–handed, while the snatcher is already far out of reach. In recent years, Apple has significantly upgraded the data security and anti–theft mechanisms in iPhones, with tools like the Find My network, Activation Lock, and Stolen Device Protection. However, most of these layers become virtually useless if the thief manages to snatch the device from your hand while it is already unlocked and open.
While Apple already integrates a time–based security delay today to prevent material changes to the Apple ID account, reality shows that a thief holding an unlocked iPhone can still cause significant damage within seconds. To close this loophole, the tech giant is currently developing a new feature that will lock the iPhone entirely automatically the moment the system detects that it has been snatched from the user's hands, similar to a mechanism that already exists in the Android operating system.
The new system will rely on a combination of several signals and sensors, led by the built–in accelerometer in the iPhone, which will be able to detect sudden and anomalous movement characteristic of a physical snatching of the device. To improve accuracy and prevent false locks, the feature will simultaneously monitor the iPhone's distance from the paired Apple Watch: The purpose of this is to understand if the device has moved away rapidly from its owner.
Additionally, once the feature is fully implemented and activated, it will take into account the same rules currently applied in the Stolen Device Protection mechanism. The system will check if the iPhone is connected to a familiar wireless network and if it is located in a fixed and routine geographical location: Such as the home or the workplace. If these conditions indicate that the device was taken from its owner in an unfamiliar location, the system will not only lock the screen immediately, but will also restrict access to the most sensitive areas of the device. Code exposed on the 9to5Mac website confirms that the feature is in active stages of development, though an official timeline for its launch has not yet been published.
