Good. Everything Google touches needs to be forked.

I hope it's functionally installable on other versions of android

I read installable and instable, I was like 🫠

yooo! while i wait for mobile linux to be realistic for my device this is a win

I've had my GV number as my primary for ~16 years. I've been on grapheneos for about a year now. Maybe I should actually pull the trigger and migrate my number to my provider and finally get RCS. All the better if GrapheneOS provides native support.

will it be usable on LineageOS? could it help with RCS support on linux?

I like how the one comment on that article is a guy baselessly saying that RCS is an open standard.

The GOAT

Hopefully this work is able to be used to help further that as well

Is RCS hosted by the carriers? If not, how to make the end run around Google?

A quick search shows that it is technically true, though..?

Open standard doesn't mean implementations are wide open to use.

Some carriers do, some never did, and some did but gave up. In the end if they want wide deliverability they'll have to connect to Google's hubs (servers).

It is annoying that Google doesn't provide an API for RCS as they do for SMS and MMS.

Fork Google

Lineage os maybe. Linux, doubt

Patiently waiting for supported devices expansion and no i don't want them to rush, i just don't want to buy a new phone to be free of Google.

For those who got too excited by the title: read the original messages from the GrapheneOS. RCS de-facto is not an open technology, there's a massive amount of work and multiple steps are needed to get anywhere near the proper independent implementation. It's gonna be amazing if the GrapheneOS team pulls it off, but don't get too excited about the release dates and its availability for other systems (e.g. Linux).

I bought a second hand pixel 8 pro.

I get the vibe there's not much intention to expand compatibility.

This would be great. Definitely one of the few missing features.

My current daily driver is an HMD Skyline and it's been great thus far and repairability is good but it isn't listed anywhere as being supported by alternative OSs.

They're working with Motorola to make a device

Go fork yourself

Only system apps can offer RCS support, so there has been essentially no 3rd party apps for it, just Google's and from a few OEMs like Samsung

It's open as BGP. Public documentation, nobody will connect to you if you're a nobody.

And Samsung gave up.

GOS team is so ambitious and I think we kinda need it too

Meh, RCS is too little, too late, and archaic in design.

We moved away from hardware-based network identifiers in the 1980's, and RCS requires a unique hardware ID. It's fucking backwards.

I will never use the garbage that is RCS - it's already dead, just needs to be buried.

What the fuck is RCS?

2 weeks now on Graphene. This is what a phone OS should be, simple, boring, juste the basics without a shit-ton of bloatware and spying crap.

Yep, I always laugh when I think that Google managed to successfully bully Apple into supporting RCS, yet Googles own service, Google Voice, doesn't!

We keep trying, but the courts are ok with monopolies.

it's trying to extend the sms/mms system

fork it right out the ass

I'm in this same boat.. FOMO is hitting me hard.

I think GV is the heaviest anchor holding me to Google right now.. :⁠-⁠\

Ok so RCS is basically WhatsApp/Signal but Google(+Carriers) but retarded:

• The client software is propiertary and screws you over when you e.g. root your phone
• They finally realized that E2EE exists - 10 years after everyone else implemented it
• You can't view the docs unless you're a Google Partner
• The protocol seems to be a mess
• You need a mobile data connection for it to work (sometimes not)
• Knowbody knows how the server software works or can be hosted, everything is "Google Jibe" or needs to connect to it to work

Only phones that can have the bootloader relocked by Graphene will be supported. New Motorola phones are coming but they will be expensive. Get a Pixel (not 11).

This has been available since forever, though. Cyanogenmod/LineageOS was the biggest. Oneplus followed along and I love my OP15, though that's coming to a bitter end

What messaging service works without a data connection?

IPoAC?

3G is shut down and 2G will follow soon.

That's just one of the things required for graphene, there are a lot of hardware security features that are also required. Only Pixels (not Pixel 11) have these so far, but the Motorola phones will change that of course.

They suddenly care about monopolies whenever a major competitor threatens to shift the balance of the market by providing alternatives...

As of now, for clarification, Pixels 6-10 series, Tablet and Fold are supported by GrapheneOS. The new Motorola phones releasing next year will also support GrapheneOS.

RCS is finally good now!

It's supposed to be out next year but only the highest end devices will be supported because GrapheneOS requires certain security features in the firmware and hardware that Pixel 11, the lower end Motorola devices, and the other brands don't/won't have.

They require certain features that most phones don't have in order to be willing to support them. They want phones with GrapheneOS to be impossible to break into even by sophisticated methods such as Cellbrite so it defeats the purpose if it can be circumvented by methods that don't involve the OS.

Very much needed.
This has been missing for years

Yeah but can you really trust pixels? Google hardware, ewww.
I would rather pay more for proper hardware

What messaging service works without a data connection?

mobile data connection.

As opposed to wifi or the pigeons you linked.

Seems like Pixel 11 has the hardware but they turned the Arm Memory Tagging Extension (MTE) off in firmware for 'performance' reasons. gOS has been able to turn it back on, but the jury's still out on whether they'll support it as I understand it.
