Update your device's software
If you didn't update your iPhone 5 before November 3, 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 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 update your iPhone 5, you can check to make sure 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.
