If you're in the view where you are looking at a specific client, you can flag it as incorrect. 

Otherwise, I suggest you log a ticket with Meraki Support.

Ya, i have raised a case with meraki support team.

My personal guess is you will find some users have their Android devices plugged into their computer, and their Android device will be accessing the network via that computer - and that Meraki is correctly reporting this.
