I've heard that you are still have performance issues with you touch event. I'm wondering, are you updating text with the "Font-Manager" bitmap font library via your touch listeners? It's come to my attention that the "Font-Manager" library has performance issues due to a lot of wasteful string parsing and regular expression it does every time you update a small amount of text. During my testing, I've discovered that updating a small amount of text via "Font-Manager" can take about 15-30 milliseconds. I shared my findings here...
So, if you are using the free "Font-Manager" library, then that might be the cause.
The "bmFont2" bitmap font library was a lot faster during my testing.
I haven't tried "TextCandy" yet.
