Problems with GPS Samsung Mobile

I have a Samsung S10e. When im using LocusMap 3.x it is running with out problems. I made an update to LocusMap 4.x, silver edition. If I let the mobile run for a track recording, the mobile doesn't find the GPS satellites, only occasionally. So that I getn't a good track. I think, maybe from 50 positions, Locus registered only one or two. I think this is a problem between the mobile an Locus. But I can' give more gps-rights to the LocusMap 4.x. This time I use your version 3.610, it is running perfect, track recording is super. But in the future I what use the 4.x version. What can I do.
