The Oppo A37/was launched few weeks earlier with good features and quality at a reasonable rate.It has very good body structure with an inbuilt 2600mah battery. It has a front camera of 5 mega pixels which is quite good for taking selfies and it also has a 1.2 Ghz qualcomm processor which makes the processing quite smooth.My friend bought this phone as it is available at good price few months back.but the problem he faced was that he used to play games on the phone and his phone used to heat up very badly and battery also drained at a very rapid rate.Even when tge phone is charging it gets heated up so easily without doing anything.so this is the major issue of this phone and I hope the company fixs this problem in the upcoming models of oppo.
