ZTE on Tuesday officially launched its amazing Axon smartphone in the U.S. and we’re giving one away for free! The device features 4K video, Hi-Fi audio, 4GB of RAM, a dual-lens camera, twin microphones, a gorgeous display, crazy battery life, and a sleek and sexy design make this an Android-lover’s dream phone.

Here are some of my favorite features of the device:

Take high-quality photos with its dual-lens camera, which gives you quick auto focus to capture the action as it happens. Shoot 4K HD videos. Or use the smile-activated front-facing camera to step up your selfie game. Fall headphones over heels with the first true high-fidelity phone available in the U.S. that lets you hear music and record sound the way they were meant to be heard. Beauty. And a total beast. Inspired by your suggestions, Axon’s super-simplified Android interface pairs full-bleed images with large, elegant type for a high-end look and feel. It also comes with a lightning-fast processor, 4GB memory and a large battery for all-around high performance under the hood.

To enter in to this giveaway, just leave a comment here on this post with your favorite feature of this great phone. The contest runs for one week, until Wdnesday July 22nd at 11:59PM EDT, and it’s open to U.S. residents only.
