I am trying to track location using
But this is what I get when I trying it in real devices (android devices)
(as you can see there is a lot of 'glitchs')
Are you seeing the same thing if you use the built-in Google Maps app? (you should be able to run them side-by-side by going into a split view).
Also are you surrounded by a lot of very tall buildings, or do you have a clear view of the sky?
Solved :) - other yet workaround
I check HorizontalAccuracy before drawing.
But it's still look weird to see the blue circle (my location) jumping and than goes back.
With Google Maps app it's not happen.
Could you also check what is in the 'AdditionalSourceProperties' dictionary on the location object you're getting, and compare a good with a bad location? This might give us some additional hints about what is going on.
