Android 10 introduced a gesture-based navigation system that did away with on-screen buttons. Instead of using Google’s controls, Samsung stuck with the three-button setup (with the Back on the right side). Fortunately, you can turn on gesture navigation (and swap the button order) on the Galaxy S20, S20+, and S20 Ultra.
Turn on Gesture Navigation
Start by opening the Galaxy S20’s Settings menu. The easiest way to do this is by swiping down from the top of the screen to pull down the notification panel. From there, tap on the Gear icon found in the top-right corner.
Alternatively, you can swipe up from the Home screen to open the app drawer. You can either use the search bar at the top of the screen or swipe through the pages until you locate the “Settings” app.
Next, scroll up and then select the “Display” option. This menu is also where you can turn on your phone’s 120Hz display.
Here, you’ll find the “Navigation Bar” button. Tap on it.
Select the “Full Screen Gestures” option to switch from the three-button layout to Google’s gesture navigation system. You can then tap on the “More Options” button if you want to change to Samsung’s gesture setup or fine-tune the back swipe sensitivity.
Google’s gestures allow you to go Home but quickly swiping up from the bottom of the screen, open the Recents menu by swiping up and holding, and going Back by swiping inward from either edge. Samsung’s system allows you to swipe up from three designated sections of the screen to go Back, Home, or launch Recents. Choose whichever setup best suits your needs.
And finally, change your Galaxy S20’s back gesture sensitivity by moving the bar closer to lower or higher. Samsung recommends lowing the setting if you repeatedly activate the Back gesture on accident.
After you enable gesture navigation, you will likely notice that the bar icon at the bottom of your screen will partially break Dark mode. You can fix this by hiding the bar completely. To do this, go back to the “Navigation Bar” menu and toggle off “Gesture Hints.”
Change the Navigation Bar Button Order
If you want to keep the three on-screen navigation buttons but what to reverse the order so that the Back button is on the left side of the screen, you can. As before, start by jumping into the Settings menu.
The easiest way to do this is by pulling down the notification tray and tapping on the Gear icon. You can also swipe up from the Home screen to open the app drawer and then tap on the “Settings” app.
Next, scroll down and select the “Display” option.
From there, tap on the “Navigation Bar” listing.
Finally, select the button order that you’d like to use on your Samsung Galaxy S20. The change will take place the moment you tap on the corresponding option.
