Help Lock Volume Control?

[Android Question]

Galaxy S5 Active. I'm forever lowering the volume apparently by the way I hold and use the phone. Is there a way to lock the volume and disable the volume buttons on the side of the phone?

I haven't tried it myself, but this might do what you need it to?

I use "Volume Locker". Simple app that doesn't disable the controls but lets you lock the levels selectively for the various audio modes- ringtone, phone, media, system. The buttons will respond but the level will stay where you locked it.
