Problem with Location Permissions on Samsung Galaxy S21 Ultra and Android 11
I'm using a Samsung Galaxy S21 Ultra smartphone with Android 11. Locus Map 4.0 will not keep tracking when the display goes off (like when I place the phone in my pocket while hiking) if the Location Permissions are set to "Only while app is in use". If I set the Location Permissions to "Allow all the time" it works fine, but I get Notifications that the app has requested my location while I am not using it. Why would Locus Maps 4 need my location if I am not using the app?
I also use another mapping/tracking app called "CalTopo" which doesn't behave this way. I have the Location Permissions on CalTopo set to "Only while app is in use" and it does not stop tracking when my phone display is off and my phone is in my pocket.
Why would I need to keep the display active for tracking while doing a day-long hike? The longest I can set the display to stay on is 10 minutes.
