So it’s an unusually non technical fix today but I didn’t really see it explicitly anywhere so: Rovio’s new game “Bad Piggies” is pretty awesome but as I was playing through it it started freezeing the interface on me. It’d keep animating and playing music but became unresponsive for periods of time. The fix that worked for me was moving the app from the SD card back to the phone’s internal memory. I have a huge 32GB SD card compared to my phones 1GB internal mem and a lot of apps so they go there normally, but for this one, moving it back on phone made a big difference.
Settings -> Applications -> Manage Applications -> Bad Piggies -> Move to phone
