Xiaomi released this mobile as a flagship phone. Bought one last month and ever since then I have never faced any lagging while multitasking as its packed with a Snapdragon processor alongside 3gb ram. Its camera capabilities are comparatively low. Redmi note 3 comes with a very neat and best in class Graphical User interface(MiUi 8), which allows us to customize our home screen and widgets. It also supports a wide variety of themes. No delay or lagging while playing 4K videos and its display is a visual retreat to the users. Also includes a remote that can be used to control televisions and satellite receivers of all most all brands and service providers. Faced no lagging issues while playing youtube videos or browsing. Delivers good graphics while playing games. Heats up sometimes but not that much. Battery backup is more than than good.
