I am using oppo A37f mobile phone which I bought last year when I saw this phone it looks good but the features of this phone is average. Only one thing which you can say good in this that is camera and the phone which I am using is only 10 months old but it’s display become pink from the corners of the phone and one of major problem in this phone is its battery backup this phone has 28500mAh battery which last maximum 3 to 4 hour this thing make me more disappoint.After purchasing this phone I feel that I have made mistake.
