You can restrict Android operating system features in device owner mode. For example, you can restrict factory reset, changing credentials, use of Google Play and Google Chrome, file transfer over USB, changing location settings, and manage system updates.

You can restrict Android features in the Feature restrictions section.

To open the Feature restrictions section:

1. In the console tree, in the Managed devices folder, select the administration group to which the Android devices belong.
2. In the workspace of the group, select the Policies tab.
3. Open the policy properties window by double-clicking any column.

   Complete the following steps within 15 minutes. Otherwise, you may face an error when saving changes to the policy.

4. In the policy Properties window, select the Device owner mode > Feature restrictions section.
