Fuck these guys... Seriously. I bought a phone off of them hyped at the idea of the ethics. It didn't work on arrival. Over 3 months later and not one single reply to my helpdesk request (other than the Automated acknowledgement of receipt).
Unbelievably bad user experience, I went from hyped at the concept of reducing my production of electronic waste to beyond disappointed at a brutally bad user experience.
The to make matters worse, they've already stopped producing spare parts for the fairphone 4 (which a friend of mine bought a while ago)... Like is that not the entire point of the phone, reduced consumption of new phones by supporting repairs. If you're going to stop producing the spares at least release the patents then.. if you really believe in the promoted ideals that you spout... Which they clearly do not.
It turns out that it's just another money hungry company hell bent on burning the planet down to see a line go up, as far as I'm concerned. All gaff to sell shite phones at higher prices.
Graphene doesn't support anything but pixels. Even if fairphone put the special chip in that graphene requires, graphene would still have to build a version for it.
They have a specific list of requirements on their site for supporting a device, mostly security hardware. Pixels just happen to be the only ones that meet that requirement right now. Others are supposedly coming though.
I can't comment on GrapheneOS, but please have a 3.5" jack. I chose the Fairphone 3 when 4 was already available because of this. I hate to have another battery to take care of, when on-ear wired headphones work so well.
