The sound quality of this phone is great as we can compare the sound quality with iphone.if we listen music than its soo clear and loud. I am using this phone since 2 month, I didnt got any problem with it no laging, no hanging its n well and nice phone for rough use. As all sumsung phone have same style and design so I dont want to say about the style and design. Its ram is good and internal memory is is also sufficient. Features and are sam But now its marshmallow 6.0. Its battery and backup is good its 2500 mah and it took about 2, 3 hours to get fully charge. Its price range is good, if we look about the product.
