Finally got my S9 tweaked how I want it, and I absolutely love it. Performance is fast and smooth, screen is incredible, camera is awesome, and I love the feel and build in hand. At this point it's giving my iPhone X a run for it's money.
I'm using an app called "gesture control" plus an XDA tweak to get ride of the navigation bar that allows me to use my S9 similarly to how I use my iPhone X, swipe up to go home, swipe up and hold for multitasking, swipe right to go back. Love it.
That along with a pixel 2 theme from exposed, the pixel 2 launcher, and using Google apps as default (keyboard, phone, messages, calendar, calculator) it pretty much feels like a combination pixel and iPhone, but on Samsung hardware and features (such as headphone jack and Samsung pay).
Only gripes about this phone are I wish it had a flat screen, had smaller top and bottom bezels, and better battery life.
Here is a video.
