OPPO A37 is not a good phone. This phone has no noise cancellation feature, no good sound reception. this android phone has battery of around 2900 mah which is not satisfactory at all because in android you must have good battery backup.
Style and design is same as other android phone. Features in this phone not up to the mark. RAM is 2GB only but in this price range we will get more RAM and ROM. Camera quality of front is also not good. Ease of use is good and this phone is reliable also. But according to me it is not worth buying this phone.
