Oppo just announced the R819 – an Android-powered dual-SIM phone. The handst is just 7.3mm thick and is a featherweight at just 110g, quite impressive for a phone with a 4.7" screen. Oppo will be providing two ROMs for the phone – a stock Android 4.2.1 ROM and a customized Color ROM.

The R819 has a 4.7" OGS LCD (One Glass Solution by LG) with 720p resolution and 312ppi pixel density. Inside is a Mediatek MT6589 chipset with a quad-core Cortex-A7 CPU at 1.2GHz, 1GB of RAM and PowerVR SGX544 GPU. A 2,000mAh battery powers the phone and there's 16GB of non-expandable storage.
