Although we already spotted it listed earlier, with full specifications and the US $299 price tag, OnePlus has now officially unveiled its new OnePlus X 5.0-inch smartphone powered by Snapdragon 801 SoC.

Featuring a completely new design, the OnePlus X is a rather compact 5.0-inch smartphone, measuring at 140x69x6.9mm and weighing in at 138/160g. OnePlus has decided to ditch the OnePlus One and Two plastic design and focus more on an an industrial aluminum and glass look.

The OnePlus X will also be available in two versions, Onyx and Ceramic. The Onyx is pretty much a standard black version with glass rear, while the Ceramic version features, surprise, ceramic back, which adds to those 22g of extra weight. The Ceramic version will be a limited edition with only 10,000 made for Europe and India.

The display on the OnePlus X features a 5.0-inch 1080p AMOLED panel and it has rather slim bezels with curved edges, something that adds to a overall quality-look of the OnePlus X. It is powered by Qualcomm's MSM8974AB Snapdragon 801 SoC, featuring four Krait 400 cores clocked at 2.3GHz, Adreno 330 GPU and 3GB of LPDDR3 RAM.

The rest of the specifications include 16GB of internal storage, expandable via microSD card slot, optional dual-SIM (which lacks microSD card slot), 13-megapixel f/2.2 rear ISOCELL sensor camera coming from Samsung, 8-megapixel f/2.4 front camera, 802.11bgn WiFi, Bluetooth 4.0, microUSB 2.0 port, 4G/LTE, 2520mAh battery and Android 5.1.1-based OxygenOS.

The OnePlus X starts at US $249 for the standard Onyx model and you will still need to get an invite. In Europe, the Onyx version will cost €269 while the limited edition Ceramic model will sell for €369.
