What system does OPPO A9 use?

OPPO A9 is equipped with ColorOS 6 system based on Android 9.0. , OPPO A9 supports 4GB/6GB (two kinds) running memory (RAM)+ 128GB self-contained storage (ROM), and expansion memory: it can support up to 256G expansion cards. The main function of this machine is the rear dual camera, and the main camera has 48 million pixels. In addition to the impressive main camera, OPPO A9 will also be equipped with a large-capacity non-removable battery of 4020mAh, but I am not sure whether it supports the latest VOOC 3.0 flash charging technology.

OPPO A9 adopts 1080*2340 full screen, with the highest measured brightness of 480 nits, NTSC color gamut of 8 1.5% and 394ppi per inch of screen pixels. To our surprise, these values belong to a higher level at the same price.

On the back of the fuselage, OPPO A9 adopts a 3D spotlight gradient fuselage, and the micro-arc curve on the back of the fuselage brings a warm grip, and the weight of the fuselage is 190g, so you won't feel tired when holding it for a long time. Vertical camera, flash, fingerprint unlocking, plus OPPO slogan and LOGO lined up, printed on the back of OPPO A9. This central axis design ensures the symmetry of the beautiful back, which is full of good feelings for me personally.
