Expected Results

It should return accurate result only when phone moves from location

It's not a library bug, but rather the expected behavior of the GPS system.
To provide a location with the best accuracy, some factors are decisive, such as: GPS chip installed on your device, visualization of the GPS constellation, atmosphere, buildings, Wi-FI and telephone signal, interference, noise...
It is normal for these coordinates to fluctuate a few decimal places, as well as the precision.
To prove this, just open Google Maps and observe the variation, using the best provider you could have on Android.
And in addition the globe is spinning, trust me!

I am also facing this fluctuate issue on Android device, and i checked that the same gps do not fluctuate in google maps.
In some cases i got the coordinate too far(50m) from device location without moving. For this i am using
Geolocation.watchPosition with these propeties.
