I have taken redmi note 4 about 3 months ago and I have to say that this one is master piece of redmi. The picture quality of this phone is amazing and when pictures taken from the HDR mode then the quality is amazing. And it’s speed is amazing no lag even when playing a heavy game and the screen is HD. Video quality is excellent. And the feature dual app is very useful as you can make 2 accounts of a single app.
