I was apprehensive at first buying an Oppo phone for the first time, as I always thought about Oppo/Vivo as camera/selfie centric brands(as they have marketed themselves like that). For reference, I might add more here that I have used Redmi Note 4 last year and Honor 7x early this year, both were good phones at their prices.
I exchanged my Redmi Note 4 against buying Oppo F9 Pro, and got a decent exchange price of Rs.7, 100/-(incl. extra Rs.3, 000/-), which was a big incentive to go for this also.
Now, about the phone Oppo F9 Pro, I am purely delighted. Not only, the camera is good, the overall performance just amazed me. Yes, I am not a much of a gamer, but I load too many apps, and must I say, it works exceptionally well.
Although working RAM you get is near about 3 GB only out of 6 GB, but it does the job brilliantly. Not even once it lagged anywhere. It breaks the common myth about the supremacy of snapdragon chips over all else.
Oppo F9 Pro has Mediatek chip and its great.
