Client scripts and UI policies are not applied to the ng_view in mobile. This is visible when accessing a record by clicking into a reference field, for example, the Change Request field on Approval records. See the steps to reproduce for a more detailed example.

1. Log in to a demo instance.
   
2. Write a simple client script to hide a field on a change_request table, for example, and apply this on "mobile" by selecting device Type both or mobile:

function onLoad() {
//Type appropriate comment here, and begin script below
g_form.setDisplay("risk",false); //change the field to any field that you want to hide on mobile
}

3. Open any [change_request] record and notice how the field is hidden.
4. Go to my approvals and remove filter to show all approval records.
5. Open an approval record for change request.
6. In the Approval for field, click the icon to the right to open the ng_view of the change request.
7. Notice the field is not hidden in this view.
