ATTENTION! If you do not have the knowledge to restore the modified files in case of problems, or you are not willing to risk, please do not try this app. It is highly suggested to have a custom recovery such as ClockworkMod, and to perform a full backup before using this app for the first time. If something goes wrong (and this may happen), you may need to flash the ROM in order to restore the correct configuration files. Please, do not use this app if you are not able to flash a ROM in your phone!
This is a very simple application for enabling and disabling software and hardware keys on rooted phones. It just append a few strings to system files as described here: http://www.gizbeat.com/2021/disable-or-enable-the-on-screen-virtual-software-keys-in-android/
Clearly, you can modify these files by yourself... the purpose of this app is only to save a few of your time!
Please, try first the method described in the link above manually. If it works then it makes sense to use this app. Otherwise, there is no chance that this app can work on your device.
If you need support, please write me by email. I will not answer anymore to 1-star comments.

This app has been tested on my S3 running CyanogenMod 11. There is no warranty that this app will work on your device. The app modifies configuration files, which may cause problems to your phone if it is running some version of Android not compatible with the procedure described here: http://www.gizbeat.com/2021/disable-or-enable-the-on-screen-virtual-software-keys-in-android/
