I was going to install an app to my device from Google Play on my desktop, when I noticed a "No carrier Samsung GT-N7000" in my device list:
(the Nexus 7 is mine)
Apparently this device is the original Galaxy Note. I've never even seen one of these devices, and there shouldn't be one registered on my account. It doesn't show on Android Device Manager.
Is someone else on my Play Store account, downloading apps/media on my credit card? I use 2FA, so I'm worried about how that could have happened. Is there anything I can do to find out more about this device?
