Google is rolling out a new security feature for Android devices that automatically reboots phones and tablets if they remain locked for three consecutive days. This measure aims to enhance data protection by requiring users to enter their PIN codes after the reboot, effectively disabling biometric logins and ensuring that data files remain encrypted until proper authentication is provided.
Upon reboot, the device enters a “Before First Unlock” (BFU) state. In this state, user data is fully encrypted, and access is restricted until the user manually enters their passcode. Biometric authentication methods, such as fingerprint or facial recognition, are disabled, adding an extra layer of security. This approach makes it significantly more challenging for unauthorized individuals to access sensitive information on the device.
It’s important to note that this feature does not perform a factory reset; instead, it reinforces existing security protocols by ensuring that devices return to a secure state after prolonged inactivity. The auto-reboot functionality is part of the latest Google Play services update and is applicable to Android phones and tablets. However, it excludes other devices like Android Auto, TV, and Wear OS.
This move aligns Android’s security measures with those of Apple’s iOS, which introduced a similar “Inactivity Reboot” feature in iOS 18.1. Apple’s implementation triggers a device restart after four days of inactivity, requiring a passcode upon reboot to access the device.
While Google has not specified the exact rollout timeline for this feature or detailed which devices will support it, the update is expected to enhance the overall security posture of Android devices by mitigating risks associated with prolonged inactivity. Users are encouraged to ensure their devices are updated to the latest version of Google Play services to benefit from this new security enhancement.
