few days ago (with now old Locus 3.34.1) I was driving and using Locus for track recording for few (maybe 7) hours. After that I was surprised to see that Locus ate 101 MB of mobile data (25 MB in foreground and 76 MB in background). I would expect that while only recording it wouldn't use any data at all (no online navigation, no sharing etc.).
I am using offline vector Lo maps.
The question: Could it be that it was caused by global raster map (OSM Classic) setting switched on? Locus map was almost all the time running in background (as a service), as I was using Sygic for navigation at the same time (which used much less data for traffic information). Anyway, if it was downloading low zoom tiles for the global raster map for the locations from GPS, 100 MB would be still too much, wouldn't it? Even for the track 500 km long.
Device: Xiaomi Redmi 4X, OS: LineageOS 15.1 (Android 8.1.0), Locus Map Pro 3.34.1. Haven't tested with current 3.35.0, though, so not sure if still valid question.
Can't tell if it is related to other similar topics complaining about excessive data usage or not.
Thanks for a great application!
