Before reporting a bug, please confirm the following:
I got Gadgetbridge from:
Your issue is:
When I set up Gadgetbridge, I (sort of randomly) set the "Step length in cm" to 100. That worked out rather well for my runs (not at all for walking, but I don't care about that) - the distance in the data for my runs almost exactly matched the actual distance I run.
However, I updated the firmware not too long ago, and the "Step length in cm" somehowe got reset to 75 (for my runs). It still shows 100 in Settings / About you, but the data from my runs now show "Average Stride 75 cm." I have tried to change the setting away from 100 and then back to 100 hoping that Gadgetbridge would reset it on the device, but it remains (in the workout data) at 75 cm. I will add (via an edit) that this annoys me because the workout data now reports my distances as only 75 percent of the true values.
This seems like a bug, but I would accept a workaround (preferably not including a complete reset of the associaton with the device :) ).
