Review device configuration settings to confirm developer mode is disallowed. This procedure is performed on both the MDM Administration console and the Samsung Android device. On the MDM console, for the device, in the "Knox restrictions" group, verify that "allow developer mode" is not selected. On the Samsung Android device, do the following: 1. Open Settings. 2. Tap "About phone". 3. Tap "Software information". 4. Keep tapping "Build number". 5. Verify that message "Developer mode has been enabled" is displayed but "Developer options" is not available in Settings. If on the MDM console "allow developer mode" is selected, or on the Samsung Android device "Developer options" can be enabled by the user, this is a finding.
