Reenable a disabled back button on the LG VOLT

Welcome to Android Central! Did you disable it somehow? Is the phone rooted?

Idk if it was disabled or how but it doesn't work. Any idea how to fix it?

Welcome to Android Central! Does the problem persist after a reboot? How about Safe Mode?

If it doesn't work, and is broken, you need screen replaced.
