This is a only mobile which I am using from last 6months and under my budget black colour I have of this redmi 4 16 gb ultimate functions.Mobile camera is very clear all the necessary features are available on camera the most fantastic feature is fingerprint lock it is something like touch without feel man.There is one more great which I like about it is dual apps feature in setting you can use any app as an double app which mean if you have instagram install in your phone so you can also make this app two. In the end I just want to say about this phone like there is no competitor of this redmi 4 in everyway.GREAT??
