BuildProp Editor is a handy piece of software developed to help you in the quest of editing build.prop and other important files of your Android operating system. Being a system file present on every Android device out there, the "build.prop" file contains plenty of properties of your system and build information which are used in many areas of your OS.
When it comes to system properties, these values are loaded when your smartphone or tablet boots. In case your current device is not rooted, you can only view these values, but you won't be able to change them. The incoporated code editor comes with syntax-highlighting for multiple languages, and a really nice and intuitive user interface. Another positive aspect of this tool is the built-in back up component which makes sure that important system files are copied before you start editing them.
If you run into issues, you can always go back to the original file and figure out what went wrong. Inside the Settings window, this app lets you adjust parameters like the primary color, accent color, background color, and other stuff related to the GUI. Here you can also change the backup location, plus enabling/disabling the automatic backup feature.
