Oppo a37f is not a perfect device at this price point. I think oppo should improve their phones. They sholud avail there phones with 3gb of ram at this price range. I think then we will get better using experience of oppo camera phones. In oppo a 37f I have got the problem of hanging and battery draining. Sometimes I charge it 100 percent and suddenly it became less than 20 percent or 25 percent. And hanging is the main problem that I ever faced. So I request you to buy another phone at this price and I think you will get better than oppo at this price range.
