Hi, thanks for your answer.
No, I think you don’t understand what’s the point with my post. Probably because as a good french, I’m not comfortable with english.
in most situations, I do not want more, I want less.
My anger is not about my use case witch is not satisfied. My use case just shows me a pretty bad engineering choice. I never use the photo module, so I will not understand most of the choices made with it, and i cannot judge if they’re good or not. My anger is about selling a so called sustainable smartphone with, for me, so poor engineering choice.
if we just take pro/cons for this wireless technology, the only pro it that : this is wireless. Is a wire so uncomfortable to use to justify using a so complicated and wasteful technology or taking risks for the usb ports ? As an engineer and an user caring about ecology, my answer is absolutely no. And for me, Fairphone as a flagship of sustainable technology have the responsibility to encourage solid and dumb technologies against wasteful ones, this is where my anger comes from.
For example, in my opinion, the fact is uses the 5G technology is not a good choice, 5G is useless, and, more, in my opinion it should stay useless if we want a more clever world. But I understand
that this is the new standard, people could have some usages i cannot understand which justify this tech. So ok, I accept this as a change, as i accepted a transistor amplifier (but not for my guitar amplifier, never 
).
For my case I’ll keep my FP3 as long as it can be and never buy a FP4 because this is for me, a bad device, which seems more about green washing than real willness to change things
and that’s all.
