No way to know who the reporter is if the issue is submitted through SDK

That is because we cannot assume that everyone who might use the Android SDK to report a bug is actually a lean testing user. It's possible that some developers might want any of their users to be able to report bugs, and these users wouldn't be lean testing users

Thanks for answering. We would decide to ask user to add their name or lean testing username in the description, so to know who is reporting the bug. But it is quite hard to control still (most of the users may forget about it).
