So I'm contemplating my next smartphone purchase, and I'm leaning heavily toward the Galaxy Note III. However I'm trying to figure out how to manage such an unwieldy phone in a gym setting, and while running. On the opposite end, I'm also leaning toward the iPhone 5S because of it's size, and portability. Are there any of you that run/workout, that also use a phablet. If so, how do you manage the size?
