This was much more evident on my Samsung Galaxy S7 Edge possible due to the fact that the bronze colored Tough armor was made of harder plastic

But now there seems to be a tacky coating over the hard plastic which provides just enough friction to keep it safe and secure in my hands throughout the day

What makes it worse is that the case is a harder plastic and the edge where the charging port is on the bottom cuts into your finger as you hold the phone

It's honestly hardly noticeable for me, and the hard plastic cover over that wraps around the rubber case is a pleasant texture and feels premium, not something I can say about most cases
