There are ZERO open source OS for mobile. ZERO. NONE.

even the ones you list doesn't have access to essential drivers. What do they do? they get the driver as binary blobs from the original image, and just ship them. So all those projects are 1) full of closed source kernel drivers. 2) stuck on a specific kernel version to be able to use those binary drivers.

So the MOST those open source versions can do, is set a different set of "system apps" everything else must be the same as the closed source OS. It's barely more than theming in practice.

> compiling all the hardware variations to have drivers and support for practically everything for everyone to get mostly the same experience regardless of which hardware they use

Again, there is ZERO open source on those. All you need to support device X is a root exploit so you can get the binary blobs. Done. Now you can ship to that device.

There is Replicant [0] which is completely proprietary blob/firmware free but it has extremely limited hardware support with only support for Samsung devices from 2011-2012.

you're wrong. I'm a previous maintenaner (before the replicant name change).

the whole project was done by teenagers extracting blobs.

then, one, a single, Samsung model was chosen as the holygrail for no other reason other than two devs had it. they worked on reverse engineering some of the essential blobs and providing very crude drop ins (thing barely functional. absolutely no power efficiency concerns, etc).

that one device then got older and cheaper and more devs got it. continue to reverse engineering.

today, a decade latet, that model is very old. functionality is still stuck on 2g or 3g for a 4g modem.

...if modem is that far behind take a guess how bad is the rest of the components.

it's a shit show. and you are correct in that this one is indeed the best example of a fully open source driver mobile.

This is false. Sent from my Librem 5, which runs FSF-endorsed PureOS.

[1oooqooq]

librem5 is a binary blob provider. and you mostly fell for a scam.

they signed the same NDA as other OEM.

your so called open source drivers are full of binary blobs, which ironically are just the chip manufacturer reference implementation code compiled, with little else.

librem5 just shouts the lie louder. it's as closed source as any other device. like raspberrypi in terms of drivers.

...and I'm not going into the illegal investment scam librem company spams every one of their customers.

Did FSF also fall for a scam? Where are the binary blobs in PureOS, show us please. Yes, firmware is proprietary, but it's the best we have. You fell for the security nihilism: https://news.ycombinator.com/item?id=27897975

There is no scam in Purism. I received all my devices, and they're as advertised.

[1oooqooq]

the scam is the illegal investment emails they keep sending to everyone who purchased from them.

about fsf. well, the least worse is still just the least worse. doesn't make it magically open source.

[fsflover]

Any source showing the illegality of the investment?

> doesn't make it magically open source

It does make the OS FLOSS, which is all they say.
