There are already a couple of alternative OS, but I only found those for #FP2. #oslist
Did you get a reply meanwhile?
Fairphone made the source code available some time ago, there are several worthwile topics based on this already, among them …
TWRP for the Fairphone 3:
Installing Generic System Images (GSI), which are custom ROMs using Project Treble to supposedly be compatible with any Project Treble phone, such as the Fairphone 3:
The developer topic about getting something out of the source code:
I believe the only fully free OS out of those bunch is Replicant. It has no non-free firmware blobs which im pretty sure is damn near impossible on FP3 due to qualcomm drivers etc
Thank you, BertG, for a sensible opinion. I’d love for the Fairphone to have any sort of free OS on it (Android or Linux, I don’t care though Linux is getting a lot closer these days without the muddled Google origins of Android) but it needs to be doable. I feel the smartest thing resource-wise for FairPhone would be for a great Linux (phone)distro to support the FairPhone and FairPhone to support that distro. I’m really rooting (hah) for that first FLOSS OS on the FairPhone. Until then I think supporting human lives and dignity in Africa, Asia, and beyond is a little bit more important than my own privacy issues. privacy comes soon after though 
Saw an interesting talk about PostmarketOS last weekend, it’s here for everyone to view: https://fosdem.org/2020/schedule/event/smartphones/
And people can help support and develop PostmarketOS!
please give a short summary for people not have time.
The text above the video is a summary 
I like to buy a Fairphone as a birthday present for a friend. However, anything with certain “mobile services” on it is not an option. Fortunately, the date is still some months ahead. Will there be “Fairphone Open” or “Lineage OS” soon? Or, alternatively, is it easy to remove any shady services and (g)apps?
Another alternative would be an FP2, but I’m not sure, whether I still can buy it (new, with full warranty).
Many thanks in advance!
Welcome to the community forum.
Regarding “official” status … Nobody knows right now.
If you are halfway tech-savvy, here’s what you can do already …
I find it interesting how people seem to have more hate for Google than love for the Planet. It seems more important to have a Google-free phone than a phone built without resorting to slavery, conflict-materials, and with sustainability in mind.
I prefer to have a Fairphone with Google, than any Google/Apple/Amazon/Microsoft/Samsung/Huawei-free phone.
Of course Open OS would be better, but in the meantime the FP2 is great, even second-hand, so I’m patiently waiting for an Open OS alternative for the FP3 (that I don’t have, as my FP2 still feels great with Lineage).
(And of course when we say “the Planet”, we really mean “mankind”, the Planet will get over it eventually. We won’t)
Not to go off-topic here but I 2000% agree with this. I’ve heard the “I care for the the planet” argument too many times and honestly people need to get exactly this in their heads. The Moon, Mars or planet Earth are just big rocks. They don’t care if we make it rain sulfuric acid or detonate every nuclear warhead we have. People that ‘care for the environment’ need to start thinking more about ‘care for the people living in it’.
Back on topic, but related to the above, caring for the people incidentally means caring for mass surveillance in a digital age. My prioritiy goes for taking care of the environment first, of course, which is why I’d prefer delaying buying a new phone. This will also send a message to FP (and other companies) to make their devices easily accessible for developers. And hopefully in the distant future even have active efforts made to push for open source OS installed by default.
I really agree to your hopes.
I am just a bit pessimistic, as this is big business and up to now people seem to care more about new features being advertised than they care about their privacy and security; as even just 5% of FP owners chose the FP-Open OS.
And on the off-topic theme:
While you are essentially right of course, I wouldn’t put the focus that much on mankind or humans, as our species - in my opinion - is rather dispensable.
And saying “Save the Planet” obviously does include the everything alive on the surface, in the waters and in the air.
Clearly it is a big effort to fully deploy a free OS and there might be tasks for the Dev team at FP that pay off more these days. But I also think that it would not be needed that everything is done by the team there. Just some details would help the community a lot to progress in a free OS for FP3 and this could even pay out at the end. I for example am willing to order a PF3 on the day where a free OS is available.
So let’s continue to hope and wait!
If “a free OS” means any free OS and “available” means that you could install and use it … this is possible already … just not from Fairphone, and not like e.g. official LineageOS, but anyway … blame your lax definition 
…
Can you also show where the monthly security updates are available? Or do you want to say that the outdated experiment system is meant for continuous use?
I’m also waiting for a privacy friendly way to use an FP3, I won’t buy one before.
Can you actually read what I quoted, and what I answered to the quote?
Else … I share your concern.
You know exactly what he meant with “free OS”, no need always to pointing out inaccuracies in such questions.
I’m glad we agree.
