How to remove black bar under Samsung phones keyboard?

When Android uses navigation buttons, there is a large black bar at the bottom of each screen for holding down the back, home, and recently used apps buttons. But after switching to full-screen navigation gestures in 2019, there is no need to do this but when you use the keyboard, a black blank bar will still appear.

This bar is particularly arrogant on Samsung phones, but fortunately, the UI can set almost everything-including anything that will delete all traces of the black bar. Depending on how far you want to move the object, you can also delete the black bar showing the gesture indicator, and the bar will be removed in all positions, not under the keyboard.

Step 1) Disable the ‘Hide Keyboard’ Button

• First, open the Settings app from your app drawer. Select “Display” from the main menu, then scroll down a bit and choose “Navigation bar.” Once inside, disable the toggle switch next to the “Show button to hide keyboard” option.
• you could disable “Gesture hints” in the same Navigation bar settings menu to remove the bar and the white line inside of it, but that breaks Android’s quick switch gesture. So to preserve full functionality while removing all traces of the black bar, you’ll need to follow Steps 2 and 3 below.

Step 2) Install Good Lock & NavStar

• Open the Galaxy Store app from your app drawer, then search for and install a first-party Samsung app called Good Lock. Once done, hit the “Open” button at the bottom of the screen, then select NavStar from Good Lock’s main menu, which will open the Galaxy Store again. Hit “Install” to add the Good Lock plugin.

Step 3) Enable ‘Transparent Hint’

• Now, open the Good Lock app from your app drawer and select “NavStar” again. This time, you’ll be taken to the module’s settings page. Here, make sure the main toggle at the top of the screen is turned on, then enable the toggle next to “Transparent hint.”
• This makes the last remaining bars of the black bars transparent in all applications using the keyboard. The white gesture indicator line will still appear, so you can still switch quickly, but now your keyboard will start at the very bottom of the screen.
