Updating Ring App
I use an iPhone 6. It won't update to the later iPhone O/S. Will I be able to update my Ring App? And if not, will my Ring system not operate any longer on my phone?
iPhone 6 Plus, iOS 12
That is up to the maker of the Ring app. They may choose to keep an older version available on the App Store so that older devices may use it. If they choose not to do so, then you will no longer be able to use that app with an unsupported iPhone model.
