Android users can anticipate a new security feature rolling out that will automatically restart their devices after three days of inactivity, mirroring a similar function already present in iPhones. This update, delivered via Google Play Services version 25.14, aims to enhance data protection by returning the device to a "Before First Unlock" (BFU) state.

The core principle behind this auto-reboot feature is to heighten security. When a device remains locked for 72 consecutive hours, it automatically restarts, entering the BFU state. In this state, user data is encrypted and less accessible because biometric logins are disabled, requiring a passcode, PIN, or pattern for access. This makes it significantly harder for unauthorized individuals to access personal information if the device is lost or stolen.

This move by Google closely follows Apple's introduction of a similar "inactivity reboot" feature in iOS 18.1. The iOS feature also forces a restart after a period of inactivity, enhancing security. The implementation of this feature in Android means that both major mobile operating systems are now prioritizing enhanced security through automatic restarts.

Initially, the auto-reboot feature was planned to be enabled by default. However, Google has since clarified that it will be an optional security feature. This change addresses concerns from users who rely on their Android devices to consistently run background tasks or receive notifications, particularly on secondary devices like tablets. Users who need their devices to remain online continuously will have the option to disable the auto-reboot.

The rollout of Google Play Services version 25.14 is currently underway. While the update itself is being distributed, the activation of the auto-reboot feature may take additional time. Users can check for the update in their device settings under Security & Privacy, then System & Updates, and finally Google Play system update.

It's important to note that the auto-reboot feature will be available on Android phones and tablets, but not on other Android-based platforms like Wear OS, Android Auto, Google TV, or Play Games for PC. This feature provides an extra layer of security without requiring a full operating system update. By delivering this feature through Google Play Services, Google ensures that a wide range of Android devices can benefit from this enhanced security measure.

While Google hasn't explicitly stated the reasons behind implementing this feature, it's evident that the primary goal is to protect user data. With the increasing sophistication of cyber threats, measures like auto-reboot provide an added layer of defense against unauthorized access.
