Hey andygood,
sorry for the long time for me to respond. I'm currently on holiday (yay!).
Could you sort out the difficulties in the meantime?
When I return I try to find someone with a S2 to run the wallpaper on that phone.
The animation plays "by itself" without any further logic by the program so I'm not sure I have a point to begin investigations.
I assume it is some kind of platform or memory constraint that makes the animation to not play fully, it's size is quite large so maybe it might not fit into some internal buffer or something.
Is the phone up to date with firmware, etc?
Yours
Dirk
