Can anyone shed any light on the below uncalibrated line items please? Unsure what they mean. Thanks.

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.

GPS Status app.... You don't have to buy pro.
Tap on orientation to bring up that menu.

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.
