Blackberry 9850, 9860 Troubleshooting: Compass

Troubleshooting: Compass

I'm not receiving an accurate reading from the compass

Try the following actions:

• If the compass doesn't point north, move your BlackBerry smartphone away from metal or magnets.

• If "Calibration required" appears at the bottom of the screen, calibrate the compass manually.

• To help prevent metal and magnets from interfering with the compass, close the Compass application before you get in a

vehicle or insert your smartphone in a holster.
