The X4 is all style, all substance. Dual LTE SIMs and a powerful 1.3 GHz processor beneath a beautiful metal alloy housing. A brilliant HD 5.0" touchscreen displays photos and videos from the 13 MP rear camera. The X4: it's a beauty of a beast.
The X4 is custom-built by Nuu Mobile's team of engineers, using only premium components. A MediaTek 1.3 GHz Quad-Core processor with 1GB RAM powers seamless multitasking between apps, games, and more. Customize your phone to your exact specifications with the X4's pure Android Lollipop OS. Use the 16GB of internal memory to keep your favorite moments by your side, or add a microSD™ card for up to 32GB of expandable storage.
The X4 will enchant you the moment you pick it up. Run your fingers along the sleek zinc-aluminum alloy casing, and feel its smooth contours against your palm. Precision engineered using twenty-two distinct processes, the X4 looks (and feels) extravagantly luxurious. And its price will take your breath away.
Movies and pictures are rendered with dazzling clarity on the X4's brilliant 5.0" HD touchscreen, featuring 1280 x 720 resolution with 294 pixels-per-inch. But you can do even more with the X4's premium touchscreen. Using SmartWake technology and Air Gestures, you can effortlessly control your phone with the swipe of a finger. Even when it's locked.
Your camera helps your family and friends see the world through your eyes. The X4 makes sure that they get a crystal-clear view. Its 13 MP rear camera is equipped with a low-light sensor to make nighttime shots as vivid as real life. And the 5 MP front camera lets you snap selfies with total confidence. Let people see the best version of the real you.
You'll never need to carry two phones again. The X4 features dual 4G LTE SIMs, which let you use two phone numbers on a single device. Instantly switch networks when traveling, and avoid steep roaming fees and outrageous data charges when you return. Supporting speeds up to 150 Mbps, the X4 puts the power of LTE technology in your hand wherever you go.
