OPPO R9s Plus is an r-series model officially released by oppo 20161June 19 in Shanghai. In terms of design, the "micro-slit antenna" of OPPO R9s is another innovative highlight of this new product.

The original 1.5-2.0mm antenna strip was changed into three thin lines with a width of only 0.3mm, and the total area of the antenna strip was reduced by 60%, thus increasing the metal proportion on the back of the fuselage to 98.8%. With the new 4G Internet access optimization technology and WiFi amplifier, the receiving intensity and downloading speed of R9s WiFi signal are also better.

The OPPO R9s series uses the fifth-generation Corning Gorilla Glass, which is the first time that the fifth-generation Corning Gorilla Glass has been used on domestic smartphones. According to the data provided by Corning, the fifth-generation gorilla glass can fall from the height of 1.6 meters, and the front can guarantee 80% nondestructive rate.

OPPO R9s Plus has a smooth edge transition, which ensures a good feel, and because of the narrow frame design, it has a good grip. The function distribution around the fuselage has not changed much. The top is a noise-reducing microphone, and the bottom is a speaker, microphone, data cable interface and earphone jack.

On the left side of the body of OPPO R9s is the volume button, and on the right side of the body is the power button and SIM card slot. The card slot 2 is designed to be compatible with the microSD(TF) card.
