Joining others in the class of 5-inch 1080p HD screens, the Vibe X encases its large, gleaming display in a slim polycarbonate shell that measures 0.27 inch thick. Lenovo boasts about the Vibe X's laser-engraved 3D finish. From a specs perspective, the Vibe X's Gorilla Glass 3-topped display should look nice and sharp with a screen resolution of 440 pixels per inch.
Weight is also on the manufacturer's mind. Lenovo fancifully describes the 4.1-ounce device as the weight of five AA batteries.
Camera specs on the Vibe X are also sky-high: a 13-megapixel sensor with BSI for the back and a whopping 5 megapixels for the front-facing camera, an 84-degree wide-angle lens.
A 1.5GHz quad-core MTK 6589T processor serves as the Vibe X's engine, and the smartphone comes with 16GB of internal storage and 2GB RAM.
Going hands-on with the Vibe X, we were disappointed to see a slightly sluggish response when we were swiping through the phone's home screens and menus, despite the quad-core processor and 2GB of RAM.
The phone isn't out yet, so here's hoping Lenovo will iron those kinks out before the Vibe X hits ship shelves. It's rare to find a relatively high-spec Android phone that judders during use these days, so those issues ought to be addressed.
We don't have pricing or availability details just yet, though we have heard that the Vibe X won't make an appearance in the US, although it will, of course, be available in other regions worldwide, and will be out in India in December.
