title: Texy=t of my app is very small on galaxy, and fills the whole screen on Vergin Mobile device
body: <p>I tried to use different xml files depending on screen size by putting them in different folders,
  layout-small, layout-normall, layout-larg, layout-xlarg.</p>
  
  <p>My Galaxy tablet is using the layout in layout-large, but
  my vergin phone and Galaxy phone are getting the layout in layout-normal folder.</p>
  
  <p>does Google pick the layouts base on screen size, not screen resolution? also in setting the font size I'm using dp, which I thought was dots per inch.  But on the vergin phone the text is really big, and on the galaxy its almost to small to read.</p>
