I am using oppo A37 from last 9 months. We can say that, this mobile is quiet better than other expensive smart phones.i am not this a perfect phone. Not only this mobile every mobiles have their disability. Oppo A37 comes in the category of best phone because it a budget mobile of Rs 9, 990.
Good about phone:
Camera: Rear camera of 8 mega pixel and front 5 mega pixel.It also have feature of ultra hd camera which clicks the picture professionally.
Features: weight: 136g Width : 71mm height: 143.1mm Thickness: 7.68mm
Battery consumption is littlr fast .
Some times slow the processer.
As my experience the mobile is best for student and elder for using modern style smartphone.
