A new smartphone protection system, already referred to internally at Apple as AutoLock, has been discovered in the code of the iOS 27.2 test build. According to several independent publications that tracked changes in the firmware, the feature is designed to automatically lock the iPhone screen at the moment the device is snatched from the owner's hands, without waiting for the standard sleep timer. At present, the mechanism operates in the background: the algorithms collect telemetry and train, but the actual screen lock is disabled by default.

Four Key Triggers for Theft Detection

According to the logic found in the code, AutoLock does not rely on a single signal but analyzes several factors at once. The first is sudden acceleration: the accelerometer and gyroscope detect a characteristic jerk typical of a phone being snatched from a pocket or hand. The second is loss of connection with Apple Watch: a prolonged disappearance of the signal or a break in the connection with the paired smartwatch, which usually remains on the owner's wrist. The third is loss of network, that is, a prolonged absence of a connection to mobile internet or Wi-Fi. The fourth is prolonged active state, when the device remains unlocked for longer than the usual interval without any interaction with the screen.

Voting System Against False Triggers

To prevent the smartphone from locking accidentally during running, a fall, or a sudden movement, Apple is developing a restraint and "voting" mechanism. A suspicion of theft can be canceled by a number of contradicting factors: a successful biometric authentication check (Face ID or Touch ID), being in a familiar location according to geodata, or active use of certain applications. Additionally, an algorithm is provided that temporarily suppresses repeated auto-locking if the system has erroneously reacted to the user's normal movements several times in a row.

Current Status and Apple's Position

At the time of discovery, the feature is in an active development stage: the AutoLock service has been launched in the background for data collection and algorithm debugging, however, the user-facing screen lock mechanism remains disabled. Apple has not published any official statements about the date of the full launch of AutoLock for end users, so any specific timelines are currently unconfirmed by the company.
