[Micromax Canvas Nitro A310/A311] AmakSevn:
In This Post I Have System Tweaks As Android has a single text file named build.prop that determines tons of various system-wide settings on your device. You need root access to edit this file, since it's stored on the system partition—but the various lines of codes it contains are actually fairly easy to interpret and modify.

And If You Don't Have Root Permissions On Your Device Than Just Go Through My Rooting Post...

Well For Editing Build.prop File I recommend Root Explorer App To you Or You Can Use JRummy Build Prop Editor

If You Are Using Root Explorer Then Open The Root Directory > System > There Will will see the build.prop File

Before Getting Started Make A Backup Of The Build.prop File So That If Anything Goes Wrong Then You Can Come Back To Initial Conditions ..... For making a backup just copy it somewhere on ur device with .bak extension

Now You Need To Click And Hold The build.prop File And Select "Open With" Then Select Text Editor ...

Now You Will Some Lines add any of the lines listed below to the bottom of the build.prop file. When you're done, make sure to save the file and reboot

And If You Are Using JRummy Build Prop Editor Then You Simply Need To Add The Lines

Alright So Here Are Some Tweaks :-
