<supports-screens android:xlargeScreens="true" />
Or you set the minSdkVersion or targetSdkVersion to API Level 11 or higher.
If neither of these is true, the user will be give the option to scale your app in a way that may make it look much worse. If you are already doing the right thing with respect to supporting various screen sizes, the scaling mode will make your app look worse. This is because the scaling mode emulates an MDPI normal sized screen. That is, your app will become a pixelated version of what it looks like on the venerable G1.
Is this what you want? Probably not. You must update your application to avoid this situation, but only if you do not already have xlarge screen support or API Level 11 or higher listed as a target or minimum SDK version.
The update to enable this on some devices rolled out yesterday. Get to it!
