This message simply means that we haven't mapped your device in our database yet. There are thousands of compatible Android devices, and we are working hard to map and verify them all. You can get the latest list by completely closing the 3DMark app on your device, then restarting it. We refresh the database every hour.
If you have an unidentified device model, please feel free to report the problem and include a link to a website detailing the hardware specs of your device.
Even if your device is not identified, your benchmark score is still perfectly valid for making comparisons.
