USO 4 LIFE This app is embedded into the custom ROM that I'm running on my sprint Samsung galaxy tab 3. (BlissRom) and like the ui and everything the developer to this app has done to make this app. Even going a far as giving you the option to download additional plug-ins if there are any available for your device . you can make any and all kernel tweaks from this app even tweaks to your build prop. And almost any other system adjustments. But please know what you are doing and always have a back up method.
