[HOW TO] Forcing apps to use full screen
So I haven't seen this posted yet so im going to go ahead and pass it on. This is not my finding but something that was used for the Galaxy tablet when I had that. Basically it forces all the apps which do not use the full screen to do so.
Steps are to download Spare Parts 2.2.1, Open it and scroll down to the Compatability box and uncheck it. Restart Xoom and your once measly apps should take up all 10.1" of real estate. Might not be pretty just yet because they are not optimized for larger screens but give them time ;)..
