I have been a loyal Windows, Android user until I got the iPad Pro and Apple Pencil, I love it so much that when my ancient Windows computer needed to be replaced I got an iMac 27" and now I'm sure I will never purchase another PC. My phone is a Samsung Galaxy Note 4 and while I have been happier with it than with any other phone I've had I do still have problems. I live in a hilly/sketchy signal area and using my phone as a phone just isn't dependable at all, and data signal make a rare short lived appearance from time to time at best. I don't know anyone close by who has an iPhone or I could answer this question myself, how good are the radios in iPhone? I know my daughter who lives 2000 miles away, says she has never had a dropped call, but I would like to hear from former Samsung Galaxy owners who are in sketchy phone areas about how the iPhone compares. I can't carry on a conversation on my GN4 without the call dropping unless I stand/sit perfectly still in only one spot in my house. When I'm in my car with the phone connected via BT it is perfect, but I really would like to be able to use my phone as a phone.
