Oppo has just announced the R819, a 4.7-inch smartphone that's likely to have high appeal to lovers of stock Android. The Chinese firm will release the handset with its Oppo Color ROM, but users will also be able to install stock Android through a relatively simple sideloading procedure. Hardware wise, it's also decently spec'd, considering that Oppo seems to have tried to cram as much as it could into the sleek 7.3mm thick (.29 inch), 110 gram (3.9 ounce) shell. You'll get a quad-core MediaTek CPU, 720p IPS display, 1GB RAM, 16GB ROM, a Sony Exmor-equipped 8-megapixel f/2.0 rear camera with an LED flash, a 2,000mAh battery and dual-sim capability. There's no word on availability or pricing yet, though unlike some China-based handset makers, Oppo's devices often wind up in the US.
