Thank you for the detailed problem report.
I have raised a ticket on our internal system, reference 18703. I can't guarantee any timescale for fixes, if you have a support contract and require a more timely fix I suggest you contact support.
I assume you are using EMDK for Android version 6.4? I would suggest using the latest version but I see nothing in the release notes to indicate this has been found before.
The team report this issue has been fixed in the latest internal build. Thanks again for reporting.
Thank you for the update. Any idea when this build will be out for the customer use?
