Modify Android Framework Values without needing APKTool using Privset

What is "Privset"?

 Privset is an android app which allows users to change non-changeable device-specific system settings through overlaying android framework with help of android's RRO and OMS systems (please look at the above for detailed info)
  It requires ROOT privilege to do that, so your device MUST be *rooted* in order to use the app
  It reads the current sta tus of your system settings and allows you to change it
