This procedure is for verifying that the sharing of clipboard data from the Work Environment to the Personal Environment is disabled and is applicable to COPE only.

Confirm if Method #1 or #2 is used at the Samsung device site and follow the appropriate procedure.

This validation procedure is performed on both the management tool Administration Console and the Samsung Android device.

Method #1: KPE RCP Sync

On the management tool, in the Work Environment KPE RCP section, verify that "Sharing clipboard to personal" is set to "Disallow".

On the Samsung Android device, do the following:
1. Using any Work Environment app, copy text to the clipboard.
2. Using any Personal Environment app, verify that the clipboard text cannot be pasted.
