How can I remove the system bars?

1. If you only show websites in Fully Kiosk Browser or play media in Fully Video Kiosk the immersive fullscreen mode which is enabled by default is usually a sufficient solution. The system bars (status bar at the top and navigation bar at the bottom) are invisible but can be pulled up and disappear shortly.

In Kiosk Mode the status bar be blocked. Check this FAQ for good solutions.

2. If you start other apps it’s the responsibility of other apps to show the system bars or put them into immersive mode. We can only force other apps by our experimental Force Immersive Fullscreen option. Be aware of hard limitations of that option. All the keyboard input and back button will be out of order in other apps.

3. On provisioned devices you can use the Lock Task Mode to securely lock/remove the status bar and reduce buttons on the navigation bar.

4. On Samsung devices you can use KNOX Settings to disable the system bars or remove system bar contents.

5. With Android 10 and older you can use the status and navigation bar complete removal options which might work with majority of devices and all apps.  These options however require additional permissions that can only be granted using ADB.

• Download and install the Android Debug Bridge (ADB) tools for Windows, Mac or Linux
• Enable Developer Options and USB Debugging on the device (Howto)
• Connect your device to the PC via USB and confirm connection
• On the computer run this command in your ADB folder to grant permission

adb shell pm grant [package] android.permission.WRITE_SECURE_SETTINGS

Use the following package names as [package] in this command:

• Fully Kiosk Browser: de.ozerov.fully
• Fully Single App Kiosk: com.fullykiosk.singleapp
• Fully Video Kiosk: com.fullykiosk.videokiosk
• Fully Kiosk Browser EMM edition: com.fullykiosk.emm

If something goes wrong while the system bars are removed you can easily un-remove them with following ADB command:

adb shell wm overscan 0,0,0,0

After granting permissions enable Remove Navigation Bar and Remove Status Bar options in Device Management Settings to remove the system bars.

6. On some Android 12+ devices you can see a Taskbar that provides a PC-like multitasking experience for large-screen devices like tablets and foldables. It is located at the bottom of the screen and offers quick access to recent or pinned apps. In gesture mode the floating taskbar can be hidden or revealed by a swipe gesture. In 3-button navigation mode the taskbar is usually integrated in the navigation bar. With some devices you can permanently disable the Taskbar in Android settings. Otherwise we recommend to use the Lock Task Mode on provisioned device.
