Want to disable the LG G3's Smart Bulletin feature? It's just a settings menu away!
Among the LG G3's many new features is Smart Bulletin, an extra home screen page located to the left of all your other home screens. You'll see it represented by a "G" in the scrolling bar of home screens.
By default it's split between the LG Health application and Smart Tips, which gives you hints about features of the phone you might not be using. If's a useful option to have, but fortunately if you find Smart Bulletin isn't for you, it's easy enough to turn off.
