Redmi note 4 is one of the best phone in this price segment under 15000 rupees, and the 3gb ram version is come under 13000 rs of price segment.
The display is quite good with 1080* 1920 resolution and 2.5d curved display.the looks and feel are good and premium but the black version of this phone is quite better than other version, the battery is very good with 4100 mh.the camera of the phone is very good but if you look for the best camera phone under 15000rs than go for moto g5 plus but if you want overall performance than redmi note 4 is the best choice.its come with snapdragon 625 chipset which is smooth and battery saver.it run on android marshmallow and miui 8.
In my opinion if you are looking for the best phone under 15000 with overall performance than redmi note 4 is the great choice in april 2017.
