I wanted to download an application but it’s wrote I can’t because I don’t have 13 update but I have 14
iPhone 8, iOS 12
The app you want to download requires atleast iOS 13. If your iPhone would run iOS 14, you would be able to download the app.
Your signature says you have an iPhone 8 running iOS 12.
You can check which iOS version is installed if you head to: Settings --> General --> About.
If you need assistance with updating your iPhone 8 to iOS 14, please see:
