Longtime iPhone user (since the first model). Considering a Note 7 as I'm unimpressed with what the iPhone 7 seems to be shaping up to be. I really like the bezel-less design of the Note 7. And I'm a physician so the S pen looks really handy. My question is this: I've always used iMessage. I guess I'd be using Whatsapp on the Note. Do I understand correctly that I could text someone on iMessage but I just wouldn't get the Delivered or Read tags? And could I still be in group messages involving iMessage? Still deciding on getting the Note 7 or waiting until the iPhone 8 next year. I have a 2 year old iPhone 6+ that works great. Just like the Note 7 screen and the S Pen.
