Tracks on OpenSenseMap are missing measurements #65

Phone: Redmi Note 12 with Android 14 (but this has happened on many other devices as well afaik)

When I start recording the resulting tracks on the OSM are very "spotty" and missing many measurements. When I look at the recorded tracks on my phone, they seem complete (I need to check that tho!).

For all I know this could also be an Issue of the OSM

I tried to check if all values reach the OSM. So I recorded for a few minutes on my phone. I then downloaded the data from the OSM and also from the app.

I actually end up with more values from the OSM than from the app. I dont know if this is intended. Or maybe its related to #66
