Issue Report: Inconsistent Speed Data in GPSLogger App v130

The speed data recorded in the CSV file generated by the GPSLogger app, version 130, is often inaccurate, showing a value of 0 or missing entirely. Description:

When using the GPSLogger app, version 130, I have noticed that the speed data recorded in the resulting CSV file is frequently incorrect. In many instances, the speed is either displayed as 0 or is completely absent from the CSV output.

I had a look at the CSV file but I can't really see what would be causing it to be missing sometimes and start working sometimes.

In the CSV logging code as far as I can tell there isn't any weird manipulating going on, the only check is for Location.hasSpeed(), and if that returns false, the value isn't logged. That you're seeing 0 indicates getSpeed itself is returning 0. That could be related to the GPS sensor on the device itself?

You're mentioning v130, is this problem new to v130 or happens in other versions. Do you have other devices you can test with to see if it's device specific?
