I have an iphone 6. A got a message from a friend today who owns an android saying "I was changing your picture in my phone and saw that I had "Location" contact for you and [xxxxx]. I hit it and it showed me a google map earth of where you are. What is that????" I realize there is a 'find my friends' feature on my phone that I don't use, and it shows me "not sharing location", and my friend does not have an iphone anyway. So what is going on? A) How do I prevent people from seeing where I am? B) How can I see where they are without both of us having iphones and enabling find my friends?
