Has anyone else noticed recently in past week or so that in Google Navigation the arrow seems to point in random directions when the car isn't moving? While driving the arrow is pointed in the correct direction but when I stop it seems to randomly turn to different directions. I thought it was my compass but when I used a car parking app the compass seems to work fine and points to the direction of the car. I wondered if it was my gyroscope but it is fine with gyroscope based live wall papers.
