I use this one on my S7 Edge. I think it's probably close to what you are looking for. It's got kind of a rubber/grippy texture to it and I love it, never have a problem with it slipping out of my hand. It's definitely a slim fit so not a ton of protection but I rarely if ever drop my phone so just wanted something with basic protection and good grip.

Edit: Found an S7 version:

So a few days ago I took a shot at trying a few of the 'cheap' $30 shoulder bags on Amazon. I ordered a bunch and this was the one that remained after a few hours of testing all of them. It holds absolutely everything despite being such a small bag (13.9" Height, 10.5" Width, 4.1" Depth). The pockets make the most sense when compared to competitors. Here is my carry list with some updates that show its full versatility (especially as a personal item when flying). Also, bag link here.

It's just the nature of it. Some cases are going to grip the curved edge more. Others, like snap on thin cases, do not grip the edge as much and are fine with this protector.

So my debate right now is to stick with this protector and a thin case, or get a protector that only rests on the flat area of the glass, and use the thicker cases.

These are the 3 Spigens I have, last 2 I believe are variants of yours, and the ones that peel up for me. First one is working with the IQ sheild.

I actually have the first one that was linked (the non-Edge version) and I absolutely love it. My roommate had a different case for his S7 and once he saw the one I got, he immediately switched.

I had the same problem with that case. Went with one of these instead and it's great.
