Very bad accuracy on Android?

[JonesWest]

Hi,

I have som trouble on some Android phones, not all. When requesting location updates I get very bad accuracy (often up to 1500m+), even though the settings are set to allow my app the highest available accuracy.

If I open google maps on the same time, same thing happens. The location is all over the place and accuracy is very bad. BUT the moment a start a route guidens in maps it gets very accurate right away - also in my app.

How do I request this high accuracy without having to turn on route guidens?

Latest I've seen it on a Samsung Galaxy S8.
