My Samsung J7 fits perfectly without the latch on the case I have it in. It is easy to put in or take out, very light and at the same time will not 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.
