I think location is = GPS and when its off apps would not be able find a location.
You can give permissions to each app separately, in the settings of each app or at first start of the app
Did you try the Gallery from Simple Mobile Tools? I have different folders for Camera, WhatsApp, screenshots etc pp.
The Simple Mobile Tools Contact app is no dialer, this is a separate app also available from Simple Mobile Tools
The My Fairphone App does a lot for me unnesary things, the only probably helpful is that you can access your support tickets and probably easily the system tests, however you don’t need the app for this. I think there is a topic here in the forum about the app, maybe do some search.
I don’t think there is any special manual for the Camera App, however yes A always indicates automatic. There are some short video tutorials on Instagram that might provide some information.
Just checked the Simple Mobile Tools contacts app and I can create groups and either put a new contact directly in it or also add all other contacts to it later.
Btw the Simple Mobile Tools Apps are all available as Pro Version “for free” in the F-Droid Store
