For me this phone has really worked well bcoz I was never into mi and I was a kid who was thinking that mi products are not that good but this product really changed my mind really budget freindly and you can say best under 15000 INR and about the features they are not latest but they are enough for your use if you have to use it for day to day life and talking about the sound system ist preety good and I am saying you that there is no earphones with the phone so if you want earphones you have to buy it seprately and the camera is decent and the colorur come in 3 options so I have used black one and it looks good and the ram is also very good 4gb is not less. So I mi think has been on a rise because of this phone so u can understand that this is ag good phone
