Smart rin was a indian brand.Recently they launched Smarton Srt Phone. Previous they launched a mobile.But that was not a good one it’s price range.But this time it’s coming with a aggressive price range with lot of good thing.Just like grills glass 3 and Snapdragon 652. But it’s not a metallic body smartphone.Thats why it’s look like cheap.And 3000mah battery was not worth it in this price segment.People need more power for all day heavy use.But it’s support Fast charge 2.0.And it’s not support sd card.So I think that’s not a great phone in this price range
