Hi friends, Presently my friend was using a oppo A37f .This mobile main cons like 1.Heating issue friends upto 58 celsius 2.This mobile was come with qualcomm processor.Then this mobile have only 4 cpu it may causes hanging of your mobile 3.charging falls within 3 hours because of this reason this all oppo mobiles are vast.
My suggestion is buy a Lenovo k6 power.It is very fantastic mobile.oppo mobiles are used only for camera.Remaining all are vast in that phone.please please dont buy the oppo a37f.
