Reviews for the Oppo A9

Oppo A9 is stylish and works well for watching videos and gaming. It has a powerful battery as well. However, given the competition, it is likely to face a stiff battle with the likes of Redmi Note 7 Pro and Realme 3 Pro.

The Oppo A9 is a decent smartphone, but its current competition makes it less appealing. At Rs. 15,490 for the only configuration, the Oppo A9 does seem to be overpriced compared to its sibling, the Oppo K3 (Review), and other smartphones at around the same price point. While the MediaTek Helio P70 is a capable processor, it is competing with the likes of the Qualcomm Snapdragon 675 powering the Redmi Note 7 Pro (Review) and the Snapdragon 710 SoC powering the Realme X (Review) and Oppo K3 (Review).
