Hi Michael Hines,
Thank you for your post and feedback!
- With our November 2020 release of Intune, we now support the capability to surface notifications while using kiosk mode. Please find documentation on these settings here: Android Enterprise device settings for dedicated devices. Do let us know if this does not solve the issues you're running into with receiving calls via Teams.
- Managed Home Screen sign-in leverages AAD's Shared device mode. If your device is enrolled as a dedicated device and configured with Azure AD shared device mode, then all of the sign-in capabilities supported by Azure AD shared device mode apply to signing in with MHS, including SMS sign-in. There are some steps you will need to take to enable users with SMS sign-in capabilities. Please find documentation on that here: SMS-based user sign in for Azure Active Directory | Microsoft Docs.
- We do not have any recent incidents around the behavior you're experiencing with Office and Office apps, but if you're still running into this, could you message us with additional details about the issue(s) for further investigation? Thanks!
Thanks for your note on the Galaxy XCover. This device is not specifically covered in this help article, though if you have specific documents to point to that you feel are misleading we would be happy to take that feedback.
