Guys keep away from Oppo A37.
I am a user of that phone it is one of the bad featured phone I have ever seen.
It had been hanged more than 5 times in a day.
The bettery service of that phone is just pale.
All of my friends who bought that phone they every one rejectef it for being weaker quality, unsmart structure etc.sound system will be slow by the passing of time.if you buy it you will deprive surely.
So as a friend I waring you to keep distance from the specific model.
