Sounds like It's implying that those two items are uncalibrated but not 100 percent sure. Most devices used to have a way of calibrating those sensors. Try installing a GPS tools app and calibrate from within the app to see if it changes.
Or save the reading (get GPS Status & Toolbox though - it's a good app to have), and just hold the phone away from any metal and turn your wrist in a figure-8 pattern about 3 times (or rotate the phone 3 times on each of the 3 axes). That calibrates both sensors.
