My friend has brought these mobile two months before Xiaomi company copies a style of Apple company. Company has given thirteen megapixel camera which is not good means the photo is editing and giving extra clearity.
Xiaomi mobiles have same features and same processor only there is size different in every mobile. Xiaomi is giving lots of variety in memory and RAM. Motorola Moto M is nice mobile as per Xiaomi Redmi Note 4.
Xiaomi company has not real android processor it designs its own processor but Motorola company gives an original android which gives friendly feel for using. Xiaomi company is not giving earphone in the box which is the cheapest thing of the company. Xiaomi has given remote control which is not working for every device.
As per my advice Moto M is the the best mobile. Moto heats but it is friendly for use on two wheeler.
