This is the only phone which is best value for money under 15 K because it has all the features a flagship phone should have. Initially it was expencive but now it is available in half price on online stores . I am using this phone since jan 2015 and it runs like it was on the first day . No heating problem, super smooth lag free operation and constant updates makes this phone worth buying even almost 2 years after its launch . you can run any game on it without any problem . Expandable memory is not availble in this phone . I went for 32 GB Modal then and I recommended the same which would be 2K more expensive than 16 Gig modal .Other drawback is its camera quality which was not as per its price then(33K for 32 GB) but for now as you can get this phone in 17 K I would say that it is not a bad camera phone in 17 K .Built quality and feel is great any one can tell with his closed eyes just by holding it that it is a premium phone . screen is very sharp and very easily viewable in direct sunlight during outdoor opration . Battery is non removable and easily last for a full day of mild usage .
