I brought this phone 1 week before and after using this phone I fall in love with this phone but little bit disappointed with display.
Excellent performance and multitasking phone
Touch is smooth and super responsive
Dual app supporter
SOUND is OK OK, not so good
Camera is OK the front side camera is better than back side
Battery is the most important part of this Mobile. 4100mh battery will give you enough juice to run the phone for two day if you are soft moderate user. For regular user it will give one day battery backup very easily
Phone and features are awesome. Some app and features are really very helpful for day to day life
Beautiful colour of phone with classy premium look of black matte make it different from another phone
MIUI 8 provides perfect user friendly with customized theme
there are many special inbuilt features provided by Redmi Note 4 are: Customized mortification bar, Second space, dual app etc.
