Can I lock the external buttons on the Galaxy S5?

[tibber13]

Every time I'm watching a baseball game or a video and I slightly bump the home button or the two soft buttons on either side my phone takes that action and I lose what I'm watching. Is there a way to deactivate those such as holding down on a button to deactivate and the doing it again to reactive? Frustrating those buttons are so sensitive. (Yes, I have the sensitive feature "off" in settings)

Thanks ... I try those ... need a case anyway as well.
