This is really strange.
After looking through this thread I went back and check with other Android devices in my house and find running DS on those are indeed not in a good condition. The frame outside the island is much as same as the Halloween version, the storage is pretty close like what everyone had described here. The force-close and restart issue seem to happen depend on the device though (tend to happen more often the older the device is). But it seem that only my currently use tab is running faster with the new DS
Also, there's a weird visual bug where if you use a dragon to battle in Arena, sometimes after the battle that Dragon is place far outside of the habitat it is in. Then that will slowly walk back toward its habitat until it got inside its habitat again. This also happened with my fast-DS-running device
