Update your iPhone 5 to resume using App Store, iCloud, email, web and other services
As at 3 November 2019, iPhone 5 requires an iOS update to maintain accurate GPS location and to continue to use functions that rely on correct date and time, including App Store, iCloud, email and web browsing. This is due to the GPS time rollover issue that began affecting GPS-enabled products from other manufacturers on 6 April 2019. Affected Apple devices were not impacted until just before 12.00 a.m. UTC on 3 November 2019.
Update your device's software
If you didn't update your iPhone 5 before 3 November 2019, it can no longer maintain accurate GPS location or use functions that rely on correct date and time, including App Store, iCloud, email and web browsing. You’ll need to back up and restore using a Mac or PC in order to update, because over-the-air software updates and iCloud Backup no longer work.
Check your device's iOS version
After you’ve updated your iPhone 5, you can check that your device has updated successfully:
Open the Settings app.
Tap General, then tap About.
Look for the number next to Software Version.
The updated software version number should be 10.3.4.
