Oppo A37 mobile are very good and camera is also good, speaker of oppo placed at bottom oppo gives much better sound output, One can see two speaker output but one is mice and other is for sound so no confusion there. headphone included in box . Phone software same as like iphone .Utilities like cleaner, antivirus, file manager good so no need of third party apps, Apps cannot be moved to SD so, downloading heavy games is sure trouble, Music in ear decent with bundled earphone do not expect more it just entry level midsegment phone. Camera output good as display is great. Support volte 4G. Gestures control is good. Looks like premium phone as display is bright and body is metalic and in unibody form.Battery backup cant be judged in few day usage but overall battery performance is not bad. Low battery mode is sure good use. Scratch guard already there, silicon cover in box.
My Suggestion is this is the best phone.
