For others wondering about KnockON

> With Knock ON you can set the phone to turn the screen on by quickly double-tapping the screen. Double-tap an empty area in the Home screen, Status Bar, or Lock screen to turn the screen off.

Huh I thought that was a stock android thing since mi UI (xiaomi) also has it.

LG was one of the first to add the feature back around 2013. Now it's more commonly known as dt2w (double-tap to wake) and is a feature on a lot of stock roms, as well as pretty much any custom rom.

I believe it is, it's just never activated. My guess is they are saving that for a later upgrade when they can't add more cameras. I loved my LG with knock on, would still use it if it could handle today's apps...

I loved that feature back on the LG G2. I think I never stopped expecting phones to behave like this, and it seems even Apple agrees somewhat, the iPhone 11 Pro I now use turns its display on when tapped once.
