Apple began to warn owners of the iPhone 5 with a pop-up message about the iOS operating system update before November 3.
Without an update, users will lose key smartphone features, including access to email, opening web pages, the App Store and iCloud services. The problem is related to resetting the week counter on GPS satellites in April of this year, which affected the operation of applications that need the correct date and time values.
The company also wrote about the need for updates on the official iPhone support site. The problem is typical only for the iPhone 5, which came out in 2012. It needs to be updated to the latest version of iOS 10.3.4 for the proper work.
Otherwise, all subsequent updates and iCloud backups will no longer be possible, since the smartphone simply will not be able to connect to the company’s networks. In this case, the update can be performed using iTunes on your PC or Mac.
According to Apple, as of October 15, only 9% of all iPhone users use firmware versions lower than iOS 12. In 2018, the manufacturer did not include iPhone 5 in the list of updates to iOS 12 – instead, the iPhone 5s received firmware.
