I am using redmi note 3 since one and half year . The phone is having unique features such as inbuilt scanner, theme section , finger print scanner, etc but it is also having some defects too . The phone works with it’s full efficency for first six to twelve months but after that the lagging and finger print scanner isssues get introduced . Also the MIUI updates ( system updates ) are having lots of issues , problems and bugs . To solve this you have to wait for the next update . Battery backup is excellent you don’t need any power bank . Camera is also descent . But I would suggest to buy any other phone ranging this price .
