Google Took a Page from Apple's Book for the Paranoid: Android Learned to Reboot Itself for Security

Google decided not to lag behind the trends of "apple" security and implemented an automatic reboot function in Android. Now, if your smartphone or tablet on the Android lies idle for more than three days, it will automatically reboot. Just like in iOS (where a similar feature appeared in version 18.1), a forced reboot complicates things for potential attackers. 

After such a "rest," the gadget will require entering a PIN code, password, or using biometrics. This creates an additional barrier to your personal information, especially if the device suddenly falls into the wrong hands.

Automatic rebooting might be an unpleasant surprise if you've forgotten your gadget for a couple of days, but from a security standpoint, it's a sensible step. Attackers simply won't have enough time to snoop around an inactive device that requires authorization after a restart. 

The update to Google services to version 25.14, which carries this function, has been rolling out since April 14th. Full deployment may take about a week, so soon your Android will become a little more "vigilant."
