Location can not be found , weak GPS

Like apparently many others, I have the problem with the GPS not working on our Fairphones 3+ with e/OS 2.7 (Android 13), both in MagicEarth and OsmAnd and other apps. Advanced Privacy is deactivated, but our Fairphones 3+ still can't find an exact location.

I have tried all the settings recommended here - without success...
