So, I can spin around like a school girl in the Maps application, and the arrow pointer will stay right with me the entire time. But if I open Google Sky Map or Star Chart, they don't work right any more. They used to work on this phone. I can move all around the sky without it moving or I might move left and it moves the screen like I'm moving right. Is that not using the same sensor? Do you think it or some other sensor needs to be recalibrated, or are the apps just screwy now?
