About our Android Client
Android Client is a full-screen HTML browser that displays Content, Loop, and Schedule on Android-based devices, but it also allows other functionalities:
- Control the device and the performance of the client application
- Communicate with content inside the Wallboard CMS
- Maintain the system
- Learn more about capabilities in Client Comparison Chart
Content Caching
Our client stores content locally, enabling playback even without an internet connection.
- Reduces network usage
- Ensures offline functionality
Time Synchronization (NTP)
- NTP time synchronization ensures accurate content synchronization by automatically connecting to the server's NTP server.
- If no NTP server is available or the connection is lost, the device will use alternative time sources like the Wallboard server system time.
- The device requests a new timestamp from the NTP server every 2 minutes to maintain accuracy, as Android devices may experience time drift, making regular updates necessary even though a single sync would typically be sufficient.
Deprecated Features
- Demo mode was removed after version 2.x.x:
Previously, demo mode allowed interactive displays that reverted to content mode after inactivity.

System Requirements
Devices that meet our minimum system requirements may not have been extensively tested by us.
While they may function as expected, we cannot ensure full compatibility or offer dedicated support.
We highly recommend conducting thorough testing before deployment.
Minimum Requirements
- Android 5+ OS
- Devices running below Android 5 are not supported.
- Devices above Android 13 are not tested and may have compatibility issues.
- Quad-core CPU
- 2 GB RAM
- 32 GB storage
Recommended Requirements
- Hexa-core CPU
- 4 GB RAM
- 32 GB storage
- Root privileges
Rooted vs. Non-Rooted Devices
Our client works on both rooted and non-rooted devices, but certain features require root access.
- Silent background updates
- System time synchronization
- Device lockdown
- WebView replacement
Internet Connection Requirements
An active internet connection is required for:
- Updates
- Time synchronization
- Remote management
If the device is offline, these features will be unavailable:
- Background updates
- Server time sync
- Remote commands
Compatibility
Our standard Android client is not officially supported on newer Android versions or commercial hardware not dedicated to signage, due to compatibility issues. However, alternative solutions are available:
Wallboard Lite
For devices with Google Play Store access, Wallboard Lite is a browser-based solution designed to handle newer Android versions.
While it is not a native Android application, it effectively displays content with certain limitations.
Challenges with Android 12+ Devices
Devices running Android 12 or later—especially those not designed for digital signage—can present several challenges:
- Limited customization and restricted device management features.
- Non-signage devices often lack root access, preventing advanced configurations.
For these scenarios, Wallboard Lite or the Browser Client (Progressive Web Application)is recommended. The Browser Client runs directly through a web browser, bypassing many hardware restrictions.
