Thank you for the answer.|
I knew all this. Now the phone is connected to mobile data all the time. I tried to scroll the map and get it to show the location name using both cellular and WiFi without result.
Strange thing is, that the satellite map of China is loading and showing, but the ones of Malaysia, Japan and Germany don't anymore.
I also tried various VPN connections all over the world since I thought it would have to do with the China internet connection...
