About [root] Soft Buttons
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/
