You can test if your device is fully "Google Android Compatible" by checking if it passes Google's Compatibility Test Suite (CTS): http://source.android.com/compatibility/downloads.html Caveat: You might need some Android development experience to run the CTS. Most manufacturers would have already run it, and maybe not publish the complete results for dubious reasons. If your device came pre-installed with Google Play, chances are that it passes Google's CTS. Now that I know this, I (personally) will never buy a tablet that fails the CTS. And I don't think I should have to hack a device to make it CTS-compatible; that is the device manufacturer's job. Posting this here for your information.
