Hello friends, The guys who are interested in buying vivo v9, friends my suggestion is that you should think
again because oppo f7 is better than it in every way like its battery backup is 3400 mah whereas vivo’s 3200 , selfie of oppo is 25 mp whereas vivo’s selfie is 24 mp and the most advantage is that oppo f7 price is 21, 990 whereas vivo v9 price is 22, 990 So, oppo f7 is better than vivo v9 in less price
