It has Q-slide (no idea what that is though, Home Touch button options (an extra button on the left with alt home buttons), and the 2nd screen is the adjustable notch hider. I use the last one and love it. Makes the phone look good, while getting the benefit of the notch.
I've never owned another LG so I don't know what else is new, though there are a TON of settings. The advanced screen temp settings are nice for sure.
Not sold on the LG store yet. Strangely, it's much smaller than the HTC store.
