The Galaxy S7 screen is not flat, so dirt gets under at the edges.
Although the screen of the Galaxy S7 looks flat, it isn't. It has a very slight curve at the sides. As a result, there is a gap between the screen protector and the surface of the phone along all the edges. It's just enough to let dirt in and get stuck between the screen and the screen protector.
I don't imagine that this screen protector is any worse than any other glass one. It's simply that a flat, rigid screen protector won't fit well to the S7.

Seems great so far. LED is a bit bright.
I haven't used all the features, but all the ones that I have used work fine. The only obvious difference from the SKY version is that the red LED that flashes when you press a button is a lot brighter.
