I am about 600 miles away from my parents, and they are having issues with their iPhones. When trying to help them out over the phone it ends up in a lot of confusion when they get in a different menu. Is there any good way for me to remotely view or control the settings app on their phones? I have a iMac running Yosemite with Xcode, they have a 4s and 5s running iOS 8. The only two options I've thought of now is a regular call or using our iPads to FaceTime each other and show just the iPhone screen during the chat. Thanks.
