Description Daniel Knobe 2013-11-12 11:04:53 UTC 
Hallo,
during my gameport on SDL2 it seems i have found a bug.
Starting my app on android works nicely and the mouseevents work without
any modification of the pc version.
But there is a problem of multiple touches.
Using 2 fingers on screen works. Using 3 fingers at the same time on the
screen will block the complete mouseinput and it doesn't come back again.
Rendering does not stop but mouseinput doesn't work anymore.

I have checked the Events after touching with multiple fingers at the same time:
SDL_MOUSEMOTION -> Does not react anymore
SDL_FINGERMOTION -> Does work as expected

Seems to be problem of the mapping from Touchevent to Mouseevent.
I have a Xperia E too and on this smartphone the
bug not occures. Seems to be a more tricky problem.

Best regards
