I am using this for past 5 months and I am very satisfied with this phone. The design of the phone is amazing and glass has metal finish case but its made up of a polycarbonate. The camera quality is wonderful its take much more clear picture. The battery life of this phone is very long lasting. This phone has a one single speaker and yes it is loud call quality is good so we have nothing to complain about but keep in mind this is a budget smartphone. Moreover, What I dont like about this product is the phone is little bit heavy and it has plastic build quality.
