There are ample of mobile phones which are very famous like apple samsung and other but if I talk about oppo A37f my friend purchase this phone before 1 year and then I use this mobile phone I am nit happy for this phone because in oppo firstlt, there is no battery backup after that there are no more features in this phone and its not a valueable phone of I compare to abother company like samsung and apple these are much better than oppo ni dout these are expensive but reliablity phones and I like both companies rather than oppo A37f
