Since the LineageOS stock camera App seems to have some trouble with the flashlight of the new camera module, and Open Camera seems to be better anyway, I installed Open Camera.
And now I would like to start Open Camera with the camera button, but how?
I managed to set Open Camera as the App that gets started when swiping the camera icon on the lock screen by resetting the defaults in Settings - Apps - Camera. Then I was asked for the desired App the next time I swiped the icon.
Alas, in LineageOS that doesn’t seem to do anything with the camera button, as it would do in Fairphone Open OS.
I can’t deactivate the stock App, and I can’t uninstall it the easy way* (I can try, but it always says uninstall failed).
I first disabled the stock App’s permissions to access the camera, that at least prevented the App from getting started with the camera button.
*I then managed to uninstall the stock App via installing Open GApps again with a gapps-config file that tells the installation to remove the stock camera App in the process. Neat feature , the stock camera App is really gone.
But even without the stock App being there the camera button doesn’t ask for the desired App.
What can I do?
