I will look for a LineageOS repo. Or would you have a link, already?
Weird thing: I uninstalled Calendar from the Pre-installed App settings, as it was showed as installed, even if not visible anywhere. After reboot, I have a trace of the installation of Carnet, even if not selected for installation: I have now an icon named com.spisoft.quicknote.Myapplication
“Of course”, Carnet is not working; this icon cannot even launch anything.
Is it an option Carnet has messed up Pre-installed App settings?
I have a backup on Seedvault. I have tried to restore the app but it didn’t work. I will investigate whether there is an APK in the backup folder.
Edit: everything looks encrypted (of course…). Did you have a specific way in mind to retrieve an APK from Seedvault? Apart from trying to restore the app from the Backup menu.
