I have already read all problem related topics in Forum, bu to me it seems that my problem is a bit different.
My fFR265s constantly adds elevation to my activities, also it gives me 2-3x 10 flights of stair climbed in a day, when I'm nowhere near that.
Example:
This was simple bike ride, same in both directions. FR gives me 350+ m of elevation, when in reality its closer to 100 (as seen in DEM corrected elevation graph)
Recorded graph:
DEM Correvted graph:
No wind, no change in weather, no water.
Also, I would go for a run on completely flat circular track and it would give me 70-120m of elevation, which does not make sense.
This would happen with every activity.
What I already tried:
-Resetting
-Cleaning the barometer port
-Calibrating before every activity
-changing Altimeter settings from "auto" to "Altimeter only" to "barometer only"
No luck.
Is it hardware of software problem?
