Redmi note 3 mobile phone runs on 3gb ram its really fast but when I play games on it for less than 30min also its the device gets heated up fast. It gets so much heated that u cannot hold it on your hand. Its processer is good I like it but just its having its heating problem. And its cost is good for less budget buyers. its design is good. and its sound is very low. And it is easy to use.
