With the new navigation gestures in Android 10, you can reclaim a variety of screen resources previously used by the Back, Home, and Recent Apps buttons. At the bottom of the screen is still a small bar. In most apps, the bar is still on a black background. Luckily, with a simple hack, you get true full-screen mode without interrupting the new gestures.
I'll tell you a short command that you can run from your computer via ADB to hide the launch bar. It requires little to no effort and can be executed with gesture navigation on almost all devices – no root access is required. It may not be a perfect solution at the moment, but it should stop you until we achieve a full-screen official 1
Before you can hide the launch bar for full-screen navigation, you must ensure that ADB is set up on your computer to use the can execute correct command.
After you have ADB installed and ready to use on your computer, you need a command window in Platform Tools to open. Tools folder so you can type in the command needed to make it all work.
Now that the ADB and the windows environment command are all set up, there's a quick fix that you need to do on your phone before you can get st with the actual command yourself. If you enable USB debugging on your phone, your computer can send the ADB command to your phone for it to work.
Now for the good things – you can actually hide the taskbar while maintaining your gesture control , Make sure you have a command window open and are ready to switch to the Platform Tools folder before proceeding with this step. If your phone is on your home screen and is connected to your computer with a USB cable, you can run the following command that matches your current screen resolution.
If you are working with 1080p 18: 9:
ADB Shell wm Overscan 0,0,0, -45
This is the screen resolution commonly used today on smartphones, which is a balance between more general visual clarity and battery life. It is very likely that you will use this command because 1080p represents the majority in terms of screen resolution. This works perfectly on the Pixel 3.
If you are working with 1440p 18: 9:
ADB shell wm overscan 0.0.0, -105
Many of the high-end flagship devices like the Pixel 3 XL and the Galaxy S10 have a screen resolution of 1440p. It offers maximum clarity, which puts a little strain on battery life, but is still solid. If you have one of these high-resolution displays, this is the right command for you.
The above commands are used as a rule of thumb and may need to be adapted to your specific device specifications. The last number in the command with the negative value represents the height of the launch bar that you see on the screen. Since there are multiple screen resolutions and aspect ratios, you may need to resend the command at a lower value until the launch bar barely disappears from your display.
Once you find a number that allows it If you want to hide the launch bar successfully, you can try out the new full-screen mode with your gestures. You can swipe up the bottom of the screen to bring up your latest apps as you would expect, but there is also a small downside. The down arrow to minimize the keyboard is near the edge of the screen (but in most cases still visible).
That's all! You can close the command window, disconnect the phone from the computer and start the day with the new gesture navigation in full screen mode. It's not the perfect solution, but if you're ready to find the altitude that suits you, it might be worth gambling with. If you ever want to reset the height of the taskbar to the default value, run the following command, followed by the Enter key.
adb shell wm overscan 0,0,0,0
This command sets the Y value of the home page. Reset the bar with the value 0 to the default position. Once the output bar is back to normal, you can also run this command on other devices you come across in the future. Some devices may work better than others, depending on how good gesture-based navigation is, but it can not hurt to try very quickly. Have fun!
