Google is introducing a new security feature for Android devices that will automatically reboot phones and tablets if they remain locked for three consecutive days.
This update, part of Google Play Services version 25.14, is designed to enhance data protection by placing the device into a “Before First Unlock” (BFU) state after the reboot.
In the BFU state, user data remains encrypted, and biometric authentication methods like fingerprint and face unlock are disabled. To regain full access, users must manually enter their passcode, ensuring that the device cannot be accessed without proper authorization. This move adds an extra layer of security, particularly if a device is lost or stolen.
Unlike a factory reset, this new auto-restart feature doesn’t delete any data. Instead, it strengthens privacy by demanding manual authentication before the device becomes fully functional again. It mirrors Apple’s “Inactivity Reboot” feature introduced in iOS 18.1, which restarts iPhones and iPads after four days of no use.
This feature will apply only to Android phones and tablets. Devices with Android Auto, Android TV, and WearOS smartwatches will not be affected. While Google hasn’t confirmed an exact rollout date or which devices will receive the update first, it’s expected that the feature will gradually be rolled out over a couple of weeks.
At this point, it’s unclear whether users will receive a specific notification explaining the reason for the auto-reboot. However, Android devices already prompt users to enter their PIN, password, or pattern after a reboot, which is likely how this will be handled as well.
Google’s latest move reflects a growing focus on user privacy and data protection. By rebooting inactive devices and requiring manual passcode entry, Android aims to protect sensitive information and make unauthorized access significantly harder. This small but impactful change demonstrates how system-level security improvements can better safeguard users, especially in situations where a device is misplaced or left unattended for extended periods.
