I want to track my vehicles as well as I want to calculate odometer using web browser which supports html5, I am using watchposition() then I found following results
I am having following devices
Device 1 : Samsung gt p5113
Device 2 : HTC 1 mini
to get internet I used hotspot for Samsung gt p5113 as there is no SIM facility available with this tablet and WIFI is not available at my place.
Then I found following result
HTC 1 mini : gives accurate result for odometer when I traveled 25 miles
Samsung gt p5113 : there was always inaccuracy in odometer reading
I would appreciate if any one can suggest other way for achieving same goal or reason for above inaccuracy.
