I'm a Windows Phone refugee so I went with the Microsoft Launcher. I tried Square 10 and liked it but it just didn't look right on this larger screen. I've only had this phone for a few days so still trying to get a feel for it but I like the ever-changing background image and the organization of the icons so far.
Nova prime. Removed status bar and nav keys. Friends thought I had iPhone x. I use double tap gesture for recent apps and nav keys pop up when I open an app. With the date, time, and battery widget I really don't miss the status bar
I usually use the atock launcher when it comes to Android devices. I feel as though LG's UI has finally grown an aesthetic identity that's both homogenous and pleasing to look at it.
Plus I like the floating second screen. The background is a Pixel 2 lice wallpaper and as you can see I like a clean homescreen with my most used apps front and center. I will admit that I do wish I could use S8 icons with the LG launcher though.
