成個 nav bar 拎走佢
Before you jump to Step 1, do note there is a downside to this. The Galaxy Note 9 uses an OLED screen, so pixels are turned off when black is displayed, which protects against aging. As a result, while the rest of the screen's pixels age, fading in vibrance slightly over time, the pixels behind the black navigation bar won't. The end result is your navigation bar will eventually look brighter than the rest of your screen when viewing full-screen content, disrupting the uniformity of the screen.
