My Samsung J7 fits perfectly without a latch if I have one. It's no problem to put it on or take it off, it's very light and at the same time won't let it fall out by itself. The material is light and doesn't feel hot (if you know what I'm saying). Also, the touch screen is fully accessible from the sports armband, there's no problem that it doesn't recognize your finger. The sound (I tried without headphones to see how it works) is great! I wouldn't even believe it was in anything. It has a key pocket and a back pocket for a credit card or ID (I think you can fit both). It also has a velcro strap that you can thread the headphone cable through to keep it from dangling.
