If you have a Galaxy S8+, you absolutely NEED this case. The S8+ is a beautifully designed phone. Looks great and feels great, But it achieves those design points by using an all glass enclosure front, back, and curved sides and corners. It's smooth, slippery, and pretty large to get a good grip on even with big hands. And it's virtually impossible to drop this phone onto a hard surface without cracking the glass, which is a minimum $200 repair. You WILL drop it, or it will creep out of your pants pocket and leap to the floor by itself, or you will set it on the couch beside you and it will immediately head for the crack between the cushions and drop through. You MUST have a strong, impervious case on this phone. Enter the OtterBox Defender. It fits the phone perfectly with a hard plastic shell wrapped in a soft rubber cover., all without adding more than a quarter inch or so to each side. Now I can comfortably grip the phone without it wriggling free, it stays in my pants pocket until I want it, and it no longer tries to run for the crack in my sofa. The case design allows full visibility of the curved phone edges, while curving up slightly at the top and bottom to make sure that even if it's dropped, the glass will not impact the floor. Exactly what I needed. Should have bought it with the phone. I learned my $200 lesson in the first week I had the phone. Good looking non intrusive design that offers exactly the protection you need!
