I have a few hundred apps and games and noticed that a few would not install. The reason is most apps push data to the sdcard, AFTER they install. A small percentage of apps push data to the sdcard DURING the install. On 2.0 level Android OS, any device with internal storage mapped as the sdcard will not install the app directly, if the app installs like mentioned above. The solution is to plug the usb into the DX2 and mount as USB Mass Storage. Then any app that would not install, now will. It is a very small amount of apps that do this, but some popular ones are in the list. The reason they install this way, is as soon as you open the app, it forces the data to the card. My apps that install this way (out of a few hundred)- All fine games, BTW BasketBall Raging Thunder 2 Jewellust Mini Squadron Special Addition Devil Huntress Steambirds Mortal Skies Can Knockdown 2 Tiki Golk 3D Air Attack 3D Guerilla Bob Humans Vs Aliens Meteor Blitz Winds of Steel added: That is 14 apps out of about 240, so 6% and simple to get around the install issue.
