I think there seems to be an issue with the ios 8 system service location options. I am constantly getting the location arrow in my status bar and a process of elimination has narrowed it done to two services: "motion calibration" (!), "compass calibration" and especially "setting time zone" The last is particularly annoying as while it is handy for travelling there is no reason for it to come on so often during the day. Is this a bug and if so how to make Apple aware of it?
