The screen of my LG K20 went black and white can I change it back

[Android Central Question]

What would cause the screen on my phone LG K20 to just turn black and white is a defect in my phone or is there a setting that I can go to to change it back

Welcome to Android Central! For LG phones, it's usually Reader Mode -- go to Settings>Display to find it. Otherwise, look for an option for Greyscale there, or in Settings>Accessibility.

Certain power-saving modes might also change the screen to black and white to save battery.
