I used this phone from last month, and it feels so smooth and stylish.I always red mi fan my gf also using the red mi and even my brother too.it has nice body with round corners which helps for superior grip.I am working mostly outside as side engineer so it comes me handy whenever I used to it for taking pictures.because whenever I enlarged the images it shows me detailed information which other mobiles of this range fail to show.its sound quality also clear and good. Battery backup is also said not good but not bad also as it come on android platform so we can’t expect it runs like our 90s mobile phones.overall I give this mobile three and half star.from my side thumbs up for red mi note 4
