I am going out on a limb here, but this topic has less to do with your phone and a lot to do with you. Stop caring about what others think(If this is it a "too big of a phone" issue"). If not, disregard. The reason I mentioned it, is because I have had this conversation before. Now that the Appleheads have larger phones, they don't ride you when they see yours. I bring mine, and did my Note 3 before the 5, and it is what it is. It is not much bigger than the S6. I have never had an issue, and it gets the job done! If you are not very good at taking care of your tech, I would not bring it. Dropping it off your lap while weight training, or laying it on the ground while weight training won't end well if you aren't careful. I don't use an arm band and I am mindful of placement when I use it. Either pocket, lap, floor.
