If you own an older model iPhone or iPad, you should check for a software update. Apple has released an iOS 12.5.6 update for older iPhone, iPod touch, and iPad models that are not able to run the current version of iOS, iOS 15.
Devices unable to be updated past iOS 12 include the iPhone 5s, iPhone 6, iPhone 6 Plus, iPod touch 6, original iPad Air, iPad mini 2, and iPad mini 3.
The update is available over the air by going to the Settings app, tapping on “General,” and then tapping the “Software Update” option.
The iOS 12.5.6 update fixes a major vulnerability that was actively exploited, so we strongly recommend updating right away if you have an older device.
