Cannot use Device Deactivation tool on Android 10 devices in Knox Manage Legacy deployment


  • Knox Manage (KM) Legacy
  • Android 10


When exporting a list of devices through KM console, the IMEI field is blank for devices on Android 10. The missing IMEI data prevents IT admins from running the Device Deactivation tool to remove certain devices from the license key.


By Google's security design for the Android 10 OS, the Knox SDK API that allows KM to read IMEIs is now deprecated.


To avoid encountering issues with the Device Deactivation tool, we recommend you keep a list of your device IMEIs outside KM.

An update is planned for KM v21.4 that implements functionality to retrieve IMEI information from Android 10 devices in Legacy deployment.
