I discovered this evening that the case I bought breaks the compass. I wasn't able to calibrate the compass until I took the tablet out of the case. The cover is magnetic to turn the screen on and off. Either the magnets they use are too strong or they cover too much area. Or this table is unusually sensitive to magnets. The case I bought was this one:

I'm curious to see if the next case I buy has the same problem.
