Exact Filtering devices for Android Market place

we have an application which is supported on devices having resolution 480*800 and above.So it is supported in supporting handsets as well as tablets.

the setting used in AndroidManifest.xml are as follows

<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="13"/>
<compatible-screens>
<screen android:screenSize="normal" android:screenDensity="hdpi" />
<screen android:screenSize="normal" android:screenDensity="xhdpi" />

<screen android:screenSize="large"  android:screenDensity="ldpi" />
<screen android:screenSize="large"  android:screenDensity="mdpi" />
<screen android:screenSize="large"  android:screenDensity="hdpi" />
<screen android:screenSize="large"  android:screenDensity="xhdpi" />

<screen android:screenSize="xlarge" android:screenDensity="ldpi" />
<screen android:screenSize="xlarge" android:screenDensity="mdpi" />

</compatible-screens>

This setting is 开发者_运维问答filtering out lot devices, more interesting its filtering out all the tablets except 7 versions of galaxy tab 10.1.

Instead of compatible-screens, I used support-screens but it was not helpful. Please let me know the mistake done my end.

Thanks.
