If you own an Android phone and notice it suddenly restarting every few days — don’t panic. Google has released a small but important security patch that could explain why.
The tech giant introduced a feature that would cause Android phones to restart automatically every three day, but only when the phone was not used. What is the goal? To keep things secure and tidy behind the scenes — and it’s a move that Apple users have already seen for a while.
Security: Inactive Android phones now automatically restart.
This update is based on a feature that has been in iOS devices since Version 18, which allows phones to automatically reboot if they have been idle for a long time.
The change may be surprising, especially to those who use a secondary device or work computer that is not used often, but it is all about reducing the security risks. Cybercriminals may target devices that remain on too long, since temporary data can be stored in memory.
Cyber attacks can be prevented by restarting Android phones
When you restart your phone, it will delete temporary files, processes and leftover data from apps and services that you have used. Although this data may appear minor, hackers love it.
With more apps running in the background than we often realise — from messaging to email to banking — keeping your device active without refreshing it increases your exposure to data breaches and privacy risks.
The rebooting of your phone won’t stop hackers, but it will make their work much harder. Google wants to encourage users with its new subtle rule.
Why Android users need to remember their SIM pin after rebooting
If you use a second Android phone or a device which is often left untouched, it’s important to remember that if the device restarts automatically, your SIM PIN will be required. You’ll either need to enter your PUK code, or ask your mobile provider for help if you have forgotten your SIM PIN.
Google hasn’t made a big splash about this update — it’s been introduced quietly. It’s important to remember that a simple reboot can make your phone safer.
It is possible that your Android was working to protect you behind the scenes if it restarted suddenly one morning.
