title: Cheap Android 7' tablet (800x480): wrong aspect ratio, circles look like ellipsis
body: <p>I need a lot of Android tablets for resale with my app. I bought some from internet (cheap chinese products) but all 7' 800x480 tablets shows circles as ellipsis (squares as rectangles), everything is stretched...</p>
  
  <p>Some are Android 2.3.3, others are Android 4.0 but all of them show stretched UI.</p>
  
  <p>Did someone have encountered the same problem?</p>
