GPS reception always returns zero speed

I have a code that successfully receives location updates from several providers and filters them to give the current best estimate.

I have added code to check the returned values ​​of Location.hasSpeed ​​() and .hasBearing () to do some calculations related to the bearing when the user is actually moving.

Everything works fine on Huawei Sonic 2.3.3, but on Google Nexus S running 4.0.4, the location of the GPS provider always returns false for .hasSpeed ​​() and 0 for .getSpeed ​​().

When I register my location receiver, the GPS provider returns true for .supportsSpeed ​​(), but it never returns the speed in the location, even if the accuracy is up to 30 m and is physically moving (in the car, on the dashboard for maximum reception, the screen is on )

Is there a difference between 2.3.x and ICS 4.x? Do I need to perform my own speed calculation, even if the reporting service supports it?

The Google Nexus S has a GPS history. I do not think this is specifically related to ICS. Have you tried Factory phone reset data and then try again?
