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.
