Ringke Textured TPU Case ($8)
Ringke offers more than a few different cases, and this one is another we can recommend. The Ringke Textured TPU case is exactly what the name implies. It's made from a durable shock-resistant TPU material and covers the entire phone.
The front has raised lips to keep the screen safe, and all the buttons and ports are easily accessible. Then, Ringke added a bunch of diagonal lines to the back for added grip. This helps you keep a grip on this big slippery phone, and disperses impacts from drops.
It comes in Clear, Bright Rose Gold or a Smoke Black/Gray.
