Why has the Device ID changed?

On the modern Android systems the normal apps don’t have access to permanent device identifiers like mac address or serial number for privacy reasons. We try to get the best Device ID based on the data available in your Android and your device. But if you reset the device or even reinstall the app the Device ID can change and we have no chance to recognize the device again. In this case you have to move a single Fully PLUS License to the new Device ID. For the Fully PLUS volume license you are required to unregister the device prior to device reset or app uninstall.

You can avoid changing Device ID if you use the device provisioning for device setup (recommended!) and don’t turn the Wifi on/off. On provisioned devices our kiosk app can access the permanent device identifiers.
