I think R9S is pretty good.
1. In terms of appearance, OPPO R9s follows the R9 design in appearance, and cleverly solves the problem of vaginal discharge and micro-slit antenna technology to make the phone look more harmonious. The 98.8% metal ratio is more metallic than the 98.02% ratio of the r9 plus.
2. In terms of configuration, OPPO R9s is equipped with Qualcomm Snapdragon 625 processor, supplemented by a 4GB+64GB storage combination, a battery capacity of 3010mAh, supports VOOC flash charging, and supports dual-SIM dual standby full Netcom.
3. In terms of photography, OPPO R9s exclusively uses the IMX398 processor jointly developed with Sony. It has dual 16-megapixel cameras on the front and rear. The rear camera supports dual-pixel focus and the aperture value is f/1.7, making the photos clearer. Especially night shots are even better. OPPO Vice President Wu Qiang said that OPPO has applied for 1,116 patents in the field of photography, and has obtained 289 core patents in the fields of anti-shake, beautification algorithms, and rotation camera fields.
4. In terms of system, OPPO R9s is also equipped with ColorOS 3.0 system. The new system still continues the simple design and intuitive interaction. ColorOS 3.0 also strengthens security this time, taking preventive measures against spam text messages, information leaks, pop-up ads, and phishing websites.
However, overall R9s and R9 plus are still very similar, but it is better to buy old than new, and r9s is still a good choice.
