I have bought my Redmi Note almost one year ago. It has many qualities to buy it. I'm narrating my opinion about this device.
Display: - It has 1080× 2340 Pixel and 6.3 inch display. The display quality is quite good.
RAM: - It has Snapdragon 660 AEI Processor. It gives very good performance.
Slots: - It has Hybrid sim slot
Main Camera: - It has 12+ 2 Megapixel camera with dual Led flash.
Front Camera: - It has 13 megapixel camera in front.
Sound: - It supports loudspeaker and also have 3.5 mm headphone jack.
Battery: - It has 4000 Li polymer non removable battery.
It's a perfect Mobile Phone for normal use. It's not a gaming phone. It heat very quickly while playing big size games.
