OtterBox Defender Series for V20
Otterbox needs no introduction, as they've been one of the number 1 brands in device protection for years. Not only that, but they make cases for just about everything. It's always top quality, military grade drop protection, and built like a tank.
The only problem with Otterbox for me is they're a bit bulky, but some prefer that. It's also pretty expensive, and you could get 2-3 cases for the price of one. Otterbox has a few different models, but the Defender series is the best-seller.
The three layers of protection, integrated screen cover, and plastic cover over the camera and scanner mean it's fully protected.
