I'm wondering if it somehow has to do with the ROM I came from (Vectus 1+1). Googling Android compass calibration yields a number of results across different devices. Unfortunately, the fixes I found were unsuccessful.
As for the GPS, I lied and didn't have a great lock at first. When I cleared A-GPS state and downloaded A-GPS (using that GPS Status app), it almost instantly went from 0/22 satellites to 8/18. Not that this info helps solve the problem, but at least the fix did work.
I really like this ROM, it's smooth, fast, very customizable, and packs some otherwise unseen features. Thanks for the hard work and your time, Dr!
EDIT: I flashed the 7/29 Mahdi build last night, and rotation has returned to normal. I want to say when this was prominent on the S3, it was because people flashed the incorrect variant. Odd that this would only be happening to me, oh well!
