How to Edit the Android Build.Prop with Essential Tweaks

Android devices use a universal build.prop that controls runtime flags when the Android system boots. Many of the properties are unique to each device, but there are a handful of build.prop tweaks that can be applied universally to virtually all Android phones. This guide will show you these tweaks, and how to edit the build.prop file.

Warning: Tweaking your build.prop can brick your Android device. The tweaks I am sharing should work without problem on any Android device, but you should always have a backup of your data and stock ROM just incase something happens.

How to Edit Your Build.Prop

The fastest method is using a root explorer app (which requires a rooted phone) – ES File Explorer, FX, and Root Explorer are great apps. You will need to mount your /system as read/writable in your root explorer options.

Navigate to your /system folder and find build.prop file, then open it with a text editor.

Alternatively, you can download a build.prop tweaker through Google Play store. BuildProp Editor and ROM Toolbox are recommended apps.

The second method which does not require a rooted phone is through recovery mode. Not all manufacturers’ stock recovery modes allow mounting of /system partition, so if this applies to you, search for how to install a custom recovery such as TWRP on your device.

If your stock recovery does allow /system mounting, you just need to connect your device to your PC via USB and open an ADB terminal, then pull your build.prop to your PC using this command:
adb pull /system/build.prop <save path, e.g. C:\MyBuildProp)

Now you can edit the file on your computer with a text editor, then push it back to your phone via ADB with:
adb push <file path> /system/build.prop

After you push the build.prop back to your device, you need to set its permissions. Continue to type the following into ADB terminal:
adb shell
chmod 644 /system/build.prop
adb reboot
