The Oppo R1 offers a 5 inch IPS display with resolution of 720 x 1280, which results in a decent enough 294ppi pixel density. Under the hood is a quad-core 1.3GHz MediaTek MT6582 processor, with 2GB of RAM and 16GB of native storage. Better make sure you're happy with that amount of memory as there is no microSD slot on the device. The rear-facing camera weighs in at 8MP with an aperture of f/2.0, which means that you should be able to take good quality pictures under low-light conditions. A 5MP snapper adorns the front of the device, and a 2410 mAh battery keeps the lights on. Oppo's own Color OS runs on top of Android 4.2.2.
So far though, Oppo has been mum about offering an unlocked version of the Oppo R1 for the U.S. market, and the FCC visit is not an official statement from the company. When released in China at the end of last year, the device was priced at 2498 Yuan ($410 USD).
