Review managed Google Android 12 device configuration settings to determine whether a developer mode is enabled. This validation procedure is performed on both the EMM Administration Console and the managed Google Android 12 device. On the EMM Console: COBO: 1. Open "Set user restrictions". 2. Verify that "Disallow debugging features" is toggled to ON. COPE: 1. Open "Set user restrictions". 2. Verify that "Disallow debugging features" is toggled to ON. 3. Open "Set user restrictions on parent". 4. Verify that "Disallow debugging features" is toggled to ON. ____________________________ On the managed Google Android 12 device: COBO and COPE: 1. Go to Settings >> System. 2. Ensure "Developer Options" is not listed. 3. Go to Settings >> About Phone. 4. Tap on the Build Number to try to enable Developer Options and validate that action is blocked. If the EMM console device policy is not set to disable developer mode or on the managed Google Android 12 device, the device policy is not set to disable developer mode, this is a finding.
