The new phone has Android 11, the old was Android 9.
And it doesn't work as expected. When I click GPS-Status on the old phone, it opens the "GPS Status & Toolbox" window. The new phone never opens the app, but shows a box with several tools (including GPS Status & Toolbox), but when I klick there, it says "App GPS Status not installed. Shall I search for it in the Marketplace?" When I klick Yes, it shows "GPS Status & Toolbox in Google Play" as installed.
As I said before, I even uninstalled it and tried again, but it still doesn't work.
