App Compatibility doesn't work on iPhone 5c
Solution 1:
iOS 11 is a 64-bit-only OS. Apps that were only built for previous 32-bit iOSes will not work on 11, which is where the incompatibility comes from.
Your iPhone 5c is a 32-bit phone, so it will not support iOS 11. As a result, there aren't app compatibility issues for it.
Apple's list of phones supported by iOS 11:
- iPhone X
- iPhone 8
- iPhone 8 Plus
- iPhone 7
- iPhone 7 Plus
- iPhone 6s
- iPhone 6s Plus
- iPhone 6
