The Oppo R1S looks absolutely identical to its R1 predecessor, it even has the same footprint and weight. The 5" 720p IPS display also remains intact, but the chipset has been upgraded.
The Oppo R1 runs on MediaTek's MT6582 chipset with a quad-core 1.3GHz Cortex-A7 processor and Mali-400MP2 GPU, while the newly introduced Oppo R1S is powered by the Qualcomm's Snapdragon 400 with a quad-core 1.6GHz Cortex-A7 CPU and faster Adreno 305 GPU. The RAM stays the same at 1GB.
Due to the new chipset the Oppo R1S is LTE-capable, but it drops the dual-SIM support. Oppo R1S offers a more capable camera than its predecessor - it features a 13MP sensor instead of 8MP. Its extra features stay the same though - HDR stills, panorama shots, 1080p video recording.
Oppo R1S runs on Oppo's Color OS based on Android 4.3 Jelly Bean. It will become available on pre-order for €290 (CNY 2,498) starting tomorrow. You will be able to choose between white and blue flavors.
Its 801inside one plus one. 805 is the next generation of chip set while 801 is an updated chip set to 800.
I love you so much
How can you compare the specs of this phone with the Oneplus One and say they are similar? The Oneplus is much faster, with the Snapdragon 805 chipset and has 3GB of ram as opposed to the 1GB on this Oppo. That's a HUGE difference.
