iPhone users, don't be surprised if you see your phone rebooting itself over and over.
That started happening to iPhones all over the world Saturday morning, thanks to a software glitch.
The bug is affecting the phones that use apps with a notification feature, such as workout or medical apps.
Apple later released an update of its IOS 11 operation system. The updated version is called IOS 11.2.
If your phone is still acting up, apple says you should go to the settings, turn off your notifications and manually install the update.
