In my FP2, there is something wrong with either the camera module, the mainboard, the software, or a combination of all of these; frequently when I open the camera, I don’t see the camera picture but a black screen (with the normal camera controls though) and messages like “critical camera error” or “camera connection lost” (first in OpenCamera, the second in the Camera app included in FP Open OS). I removed and reattached the camera module, and it has continued even after completely reinstalling FP Open OS (not just factory rest, full reinstallation). I can’t reproduce it at the moment (indoors), but it happened quite frequently last weekend when I was on a city trip (where I mostly (tried to) use(d) the camera outside in 5-10°C, so maybe it’s related to the temperature?
I’ve seen a similar issue described here: Error critical camera: is to unscrew really the certain solution?
But it’s not the same issue as in my case: for me, the error doesn’t always happen; when it occurs, it occurs for about 2 to 5 times when starting and stopping the camera; afterwards it starts working all by itself, I don’t need to open the phone and unscrew and reattach the camera module, or even press the phone where the camera module is located.
This other post looks most similar: Rear camera: serious camera error
There it seems to be fixed by tightening the screws, I will try that.
Haven’t looked at that one yet: 🇩🇪 Neues FP2 - "Keine Verbindung zur Kamera möglich" / Fairphone 2 & Camera error
I’ll only try it as a last resort…
Oh and just saw this collection of other issues: Camera Error: Can’t connect to the camera
So this happening occasionally seems not too uncommon?
