Android app showing up in Google Play search only on certain devices

Question

I have tested my app on 2.2, 2.3 and 4.0. It works as designed on all versions. When I search Google Play Store from my Samsung Phone, both the Free and Paid versions show up in the list. When I search from my Tablet (Double Power T708) neither app shows up. Apps do show up so I know it is not the connection. I have looked at the device compatibility list and the T708 is not listed, but then how are the other apps showing up???

Below is my AndroidManifest.xml. I am hoping someone can help me shed some light on this.

How long ago did you publish the app? Google play takes awhile to update the devices that can use your app. I know that when I first uploaded my app, google play said that there were a wopping total of 0 devices capable of using the app.
