Galaxy 10.1 runs app slower than Thunderbolt

So I recently created a game with several activities. On my HTC Thunderbolt, all parts of the game seem to be running very fast; however, on my Galaxy 10.1, two of my five activities are running extremely 开发者_运维知识库slow (i.e. screen fading is slow, enemies and cursor are moving slow as well). I don't know what is wrong. The other activities are running at or at least near the speed my thunderbolt was running at. Can someone please help me?

Try enabling hardware accelerated graphics, which is available on Android 3.0+.

Or, if you are serious about game performance, use OpenGL instead.
