The Oppo N1 was the first Android device to ship running CyanogenMod, and the Find 7 was one of the first major handsets to pack a quad HD display. Now the company is pushing the limits yet again the Oppo R3, which it claims is the world’s thinnest LTE phone at just 6.3mm. To the best of our knowledge Oppo is telling the truth, though the 3G-capable Gionee Elife S5.5 is still noticeably thinner at 5.5mm.

The Oppo R3 features a sleek metal design in black or white that looks a bit like the iPhone, though it offers a significantly bigger 5-inch screen. Under the hood the Chinese company clearly had to cut some corners to keep the device as thin as possible. That means you’re getting mostly mid-range specs, including a 720p display, a Snapdragon 400 processor, a 2420mAh battery, 8GB of storage with microSD support, 1GB of RAM, an 8-megapixel rear camera, and a 5-megapixel front-facing camera. The R3 runs Android 4.3 with the company’s own Color OS on top.

Oppo’s new smartphone will be available for purchase in China starting next week for ¥2299 (roughly $370). There’s no word on whether the R3 will get a global launch, though considering the company’s recent efforts to break into Western markets we’re not ruling out the possibility of a U.S. release down the road.
