Default [Q] Nexus 4 Soft Buttons Not Responding/Digitizer Broken?

Greetings,

My Nexus 4 kissed the floor and since that event, the soft buttons (Back, Home, and Recent Apps) and the area directly above them, will not register touch input.

In what reading I did so far, I assume the "digitizer" is broken?

Can anyone confirm this?

Thanks!
