Selecting the right Android player is crucial for carrying out a successful Digital Signage project.
Wallboard cannot take any responsibility for performance if the player used is not adequate for the content that you are trying to run.
We recommend that our partners always test devices before they order a large quantity.
Rooted Android devices are always recommended.
With root privileges, our application can access system functions such as time sync, remote device restart, and be able to update the application in silent mode.
Supported device line-up
There are numerous Android devices, and it is daunting to choose between them. We've categorized devices by price and performance to help you find the best fit for your needs.

How does Our Android Client work?
Our Android client displays Content, Loop, and Schedule. It is a full-screen HTML browser that also allows other functionalities:
- Control the device and the performance of the client application
- Communicate with content inside the Wallboard CMS
- Maintain the system
Content Caching On Android
Our client application stores all components of a piece of content on the device storage and supplies the embedded browser locally. This allows the device to load in the content without an internet connection.
The cache also reduces the network traffic significantly because media files are downloaded to the device only once, and when you display content that includes media, the device will initially load it in from the local storage.
NTP Time Synchronization on Android
NTP time synchronization is used to provide an accurate base for our content synchronization.
NTP (Network Time Protocol) synchronization works automatically if the server (that the device is connected to) has an NTP server. If the server does not have an NTP server, or the connection is lost between the device and the NTP host, then the device will search for other time sources, like Wallboard server system time.
The device requests a new timestamp from the NTP server every 2 minutes to ensure content synchronization is accurate. In theory, it would be enough to synchronize the time only once. However, sometimes the time on Android devices can deviate so it has to be refreshed regularly in order to have the most accuracy.
Does my device need an internet Connection?
Since our application communicates with our server it is mandatory to enable the wifi or an Ethernet connection for communication. However, when the device is successfully registered and caches the Content / Loop / Schedule it can be run in an offline mode.
The below features are unavailable if you run the device in offline mode:
- Background updates
- System time synchronization to a server clock
- Receive any command from the server
Does my device need to be rooted?
It is recommended to run our client application on a rooted device, but it can also be run on non-rooted devices.
The below features are unavailable on non-rooted devices:
- Background Updates
- System time synchronization to a server clock
- Lock down device
- Replace WebView
Demo mode (deprecated since 2.0)
Demo mode is not available after 2.x.x version
DEMO mode can be enabled in the device configuration dialog box.
In DEMO mode the device behaves the same as in DISPLAY mode until it gets a touch event.
This touch event could be global or on a chosen image. Once the touch occurs the device will finish displaying the content.
At this point, the device switches to the default Android Launcher and the user can look into the phone or tablet while the Android Settings (or other selected applications) are disabled. After 30 seconds of inactivity the device continues working in DISPLAY mode.
We also have a lifting module that could be enabled. This feature detects if the device is lifted up and in this case it disables the 30 second timer.
