Oppo mobile a37 is not too good Bcz he say that this is VOLTE phone bt actually this is not Volte because when you are trying to video call though calling then u cannot create a video call. You have to use any apps to video call like whatsapp Skype etc. And after 6 month battery backup gets down. And one more important thing that while charging or internet using the mobile is getting too heat and somrle time mobile get slow .and rear camera is not too good as compare to front camera.
And price is high Because as this price you can prefer other brand mobile with more features.
