LG G2 Black Screen Issues

[Rich Riley]

If I'm in a club or anywhere that has bad lighting my LG G2 will not light up the black screen to unlock by knocking or by pressing the back button. Once I find light it works. I'd hate to have my car break down at night. I couldn't call for help if it did. Can this be fixed? I looked in Settings under Security, Display, Home Screen, Lock Screen. No luck.

Try a factory reset and see if that will fix it.
