Basically the redmi note 4 is available in 2 GB and 16 GB storage and 3GB 32GB storage 4 GB 64 GB storage. And it available in 4 colours that is not black silver grey and gold. I like the metal unibody designs with 13 megapixel camera and Dual tone LED flash and it as a mic on the back of the mobile in the top we have a IR blaster for controlling appliances like TV and AC and 3.5 mm audio jack to the friend he does a 2.5 D curved glass which is used for smooth touching and a 1080 p resolution screen. This phone comes with backlit keys basically xoami mobiles will not come with a backlit keys. And this mobile has 4100 MAH battery. Coming into the software mobile has Snapdragon 625. Processor basically this phone does not heat up why we play heavy games like Asphalt 8 NOVA 3 etc. With this 4100 MAH battery we can easily last for 2 days for average user for heavy uses it easily comes for 1 day my conclution is that it is a big best budget phone we can buy it is affordable and a best flagship in xaimi
