[URGENT] Navigation Bar Not Working

[ImbaWind]

Hi everyone here's the screenshot:

I've dropped my phone several times, most serious time broke the digitizer a little bit (below the screen part), but it managed to survived.
Today I found that the navigation buttons are inresponsive, but it managed to work after a off/on screen. The time I got home today, the navigation bar part completely not functioning as you can see in the screenshot. Currently I'm using GB's pie control to make the phone usable.

Any solution/tips/experience to share ?

FINALLY

I tried so many wonky workarounds, but finally found a flashable zip that worked like gangbusters. Just google "nexus 4 navfix." Hope it works for you too.

Reboot the phone in safe mode
