Apple recently released the latest security update iOS 12.5.7 for the iPhone 5s, which has been on the market for 10 years. This version is also applicable to some old iPhones and iPads.
The security update iOS 12.5.7 is available for iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation). This security update addresses an issue where malicious content on the Internet might cause the phone to run arbitrary code.
This problem existed before the launch of iOS 15.1. The latest iPhone users have been protected through system updates, but old phones such as iPhone 5s and iPhone 6 that have not been upgraded to iOS 13 are still facing related threats. The launch of iOS 12.5.7 this time can be said to be a solution for these old phones.
