the compass measures the local magnetic field, and as such might be influenced by various electronics devices around the phone. For example, try using a compass application and move near/far a PC, and you'll see the pin tilting towards it sensibly.
In other words, the accuracy of the compass is not very great and you should expect some deviation. I can't comment the exact range but deviations of 10% are not unheard of according to a few tests we made, when indoor an engineering lab. Of course, when outdoors, things should be a lot more accurate.
