I marked the procedure @kraemera as a solution. The annoying part remains thinking the phone screen is off though it is only Aurora App showing black picture.
Does anyone know why, on 4.6 and 5.0, installing something from the Aurora Store causes the installation dialog to open in a new ‘app’ in the first place? It wasn’t like this on 4.5.
When you install something from F-Droid, the installation dialog just opens inside of F-Droid, as it should. This is also the way the Aurora Store worked on 4.5.
I’m not sure, but in 4.4 or 4.5 they did some updates to the AAS to have higher Android API -level (or what ever the thing is called) compatibility, like the webview component etc. if I recall correctly. Probably one or more of those changes causes this issue as side effect. After the update there were other issues as well, like applications that previously worked, didn’t start anymore or showed a black screen until you managed to blindly hit something on the app, that caused the view to update. All of those should be now fixed, so I’m hopeful they’ll manage to fix this issues also at some point.
This seems to be fixed in SFOS 5.0, and while the prompt to install the packages still opens in a new window/tile (instead of an overlay), I don’t have to rotate the phone anymore to redraw the screen after returning to Aurora Store.
