[root] Soft Buttons is a free personalization app for rooted Android devices. It allows users to enable and disable software and hardware keys by appending a few strings to system files. The purpose of this app is to save time for users who want to modify these files without doing it manually. However, it is highly suggested to have a custom recovery such as ClockworkMod and perform a full backup before using this app, as it may cause problems to your phone if it is not compatible with the procedure described on the developer's website.

It's important to note that the app has been tested on the developer's S3 running CyanogenMod 11, and there is no warranty that it will work on all devices. If you encounter any problems, the developer offers support via email, but they will not respond to 1-star comments.
