I just installed Fairphone Open and updated to 18.01.01. Everything’s working well, except that there’s no camera icon either on my home screen or in the app drawer (as in: the thing you get when you press the middle icon at the bottom of the home screen, the one with six dots - that should contain all apps right?).
That said, the camera is installed. For example, when I can upload an image in Firefox, I can select Camera as an option, and can then use that to take a picture.
(I don’t know: some core functionaloties are sometimes duplicated.)
If you can open it with the Camera side button, then it’s a fault of the launcher. Try what @paulakreuzer said and after that reset your phone (as in power off-power on, not as in wipe)
Hmm, for some reason the cache and app data clearing buttons are not present. This might be related to there not being anything yet, seeing as it’s a fresh install on a new phone.
I can open it with the camera side button, now that you mention it, so it’s probably a launcher issue. Just not sure what to do about that
