I am trying to avoid a click-bait title. Some apps are breaking on Android Pie or Android 9
F-Droid – Unable to assign “Unknown apps” permission, because it does not appear in the list.
ES File Manager – same as above
Wifi Automatic – Cannot turn on/off Wifi
Tap’n’Turn – After screen lock, it is unable to rotate the screen
Jabra Assist – Crash on launch
Android Pie is currently cutting-edge software, so some apps breaking or ‘bleeding’ is to be expected. The issue that most concerns me is that the app must be recognized by Android to be able to given permission. Before Android Oreo, there is a master switch to allow the installation of non-Play Store apps by enabling “Unknown apps” in Settings. From Oreo onwards, this is done on a per-app basis.
What if one day Android decides not to recognize any app for “Unknown apps” permission? Thus blocking all third party apps?

After some searching, I have decided it might be due to all the layers of Alpha code. So I wiped the system partition, and put back Magisk and Gapps. All the apps lost their permissions, and F-droid permission prompt came!

Last Nitrogen build 13 Sep got the Jabra app working!
