I am also Oppo A37f user
2GB RAM & 16GB ROM: very less storage space
This phone has very bad heating problem.and very poor bettry backup only 2630 mAh bettry.This phone is only for camera phone 8mp rear camera and 5 mp front Camera and others features are very bad like( bettry, storage, gameing performance, heating problem, sound quality, and very slower app performance compering others phones.) and yes This phone has without fingerprint and face unlock option.
So that, I give negative review for Oppo A37f phone.
