Jolla C: main camera shows no live picture and stays black

Occasionally it happens that the main camera will not show a live picture. Instead it stays black and no picture can be taken at all. The front camera still works though. I cannot reproduce it willingly, it happens randomly (and as Murphy suggests often in the funniest moments I'd like to capture). Also it will not reappear for sure after rebooting the device. Then it suddenly works again (sometimes).

Is this a hardware issue with a loose connection from the camera to the board or the camera itself? Is this software related? Someone else who experience this? Any suggestions what to do?

I don't own a Jolla C, but either of your suggestions could be the case (loose connection or software problem). Before any dismantling of your device, I would be tempted to remove the camera application from the device and install again. Removal of the camera needs to be done via Terminal, using the command pkcon remove jolla-camera and to install, use pkcon install jolla-camera (I am assuming that jolla C is using the same software as my Jolla1).

For me the same issue: After Fiskarsinjoki-update - It started exactly as in your description. For now my main camera permanenty stays black while the front camera works. Camera-software removal and re-installation: negative result. Complete system-reset and test before and after updating to Fiskarsinjoki: negative result. Check for hardware connections: no visible defects... Anyone an idea? - (I´m afraid the hardware of the C is crap.)

My Jolla C developed the same problem during this summer (Iijoki, wasn't fixed by updating to Jämsänjoki). Front camera works fine in Whatsapp etc., but main camera doesn't even seem to be an option anymore (first it just complained about not being able to contact it). I'm sort of hovering between trying the whole uninstall-reinstall stuff and just bearing with it until Sailfish X...

@ragzy - The camera package comes in 2 parts, try installing 'jolla-camera-settings' first, that's how it works for Jolla1....pkcon install jolla-camera-settings

The evening I posted I got the camera working again after reinstalling the camera with the command pkcon install-jolla-camera (I just needed to refresh pkcon).

BUT today the camera was black again (pkcon install jolla-camera-settings did not help, but thank you for the suggestion, that command seems to install the other packages too), occasionally the front camera is working, but not the back one. KiK worked saturday (can´t recall if it was both front and back) and another android camera app worked, but today KiK says it can't connect to the camera and asks me to close any app that is using the camera.

When I run jolla-camera I get:

[D] unknown: 0 - using wayland-egl
[W] unknown: 0 - CameraBin error: "Could not initialize supporting library"

I have a similar problem with my Jolla 1. Camera screen stays black as well, interface opens properly... In some android apps the front camera works fine though...

Terminal shows this: https://1drv.ms/i/s!AuG_41MNCmhVxF9H_Hy-IjKqkFpX

Has anyone an idea how to fix that?
