I have been using my LG V30 as my main device for the past week. I am still having a hard time remembering to tap the app drawer button to bring up the app drawer. I have become so accustomed to swiping up to reveal the app drawer. This is the action in the Pixel launcher which I had installed on my previous devices.
The latest Pixel 2 launcher with the bottom search bar is now available for download and should work on Any Android device with Nougat or better. You won't be required to install this on the system partition so you don't need root to make this work. While you are at it you might as well go ahead and grab the PIxel 2 wallpapers app as well.
