I'm not a gamer or a heavy social media user. So I don't know if the FairPhone 4 is a good choice for that, if that's your thing. Probably not from what I've read.

It's plenty good enough for my needs though. It feels like a good mid-level cellphone from 3 years ago - with the price of a top-tier cellphone of today though :)

I like the Fairphone 4. It has one annoying bug that the Fairphone folks are taking an inordinate amount of time fixing: random screen dimming when the phone gets hot in the sun. Other than that, it's been absolutely flawless for me. Hopefully the screen dimming issue will soon get resolved.

Bonus: the Fairphone 4 supports charging control, and CalyxOS has the option enabled. That makes it the only phone I know that supports this apart from Pixel phones!

As to your question re pictures: I'm not much of a photograph, but I've read the cameras are nothing to write home about. They take very decent pictures for me though. Maybe I'm easily pleased... If you install Open Camera to replace the crummy stock Android camera app, it has a button to select the wide angle camera or the regular camera. The latter can focus onto stuff maybe an inch away. Not sure if that's enough for you. I can shoot a sample photo if you want.
