which Gemini Joytab are you using? What Android version are you using on it?
What exactly happens when you try to install/run the application?
It is a Gemini Joytab 9.7 Gem 10212 Android version 4.0.3.When run the application I get the blue start up screen, then after a moment a black screen with Adobe Photoshop Touch displayed in the top left corner and it stays on that screen.
I contacted you privately so that you can share some more information.
