Android 4.2.1 GPS distance error

 

Update 15 Feb

The root cause was CM 10.1  had a code error and the fix was implemented on 6 Jan 13. link  I flashed the latest MCM nightly, dated 6 Feb and did a test by walking a short distance.  It appears to be fixed.  I need to test drive it on a longer workout. Looks like super powers have been revoked.
