Chinese smartphone maker OnePlus on Thursday officially unveiled its third smartphone at a press event in London. As expected, the OnePlus X is a mid-tier device priced at an attractive $249 sans contract. Here's everything you need to know.

It starts with a 5-inch full HD AMOLED display (441 PPI) with Gorilla Glass 3 coating that's powered by a quad-core Qualcomm Snapdragon 801 processor clocked at 2.3GHz and Adreno 330 graphics alongside 3GB of RAM. There's only 16GB of local storage but fortunately, there's a microSD expansion slot to fall back on. A 13-megapixel camera with f/2.2 aperture gets the job done around back while an 8-megapixel shooter handles selfies and video calls.

Other noteworthy features include 802.11 b/g/n Wi-Fi, Bluetooth 4.0, a dual SIM card tray and a 2,525mAh battery. The handset runs the company's own OxygenOS which is based on Android 5.1.1 Lollipop. There's no home button on the front of the device but you do get an alert slider on the side to switch between three different notification profiles like on the OnePlus 2.

The standard OnePlus X will set you back $249 when it arrives in the states on November 19. There is also a limited edition ceramic version of which only 10,000 are being produced (versus the standard black glass on the rear) that'll command an extra $100. It's only being sold in Europe and India.

OnePlus is continuing its frustrating invite-only system so you'll want to get your name in the hat ASAP should you be interested.
