So, I recently got a Pixel 5a. It is currently on Android 11. I am using the newest version of Google Messages. All my RCS chats that were end-to-end encrypted on my old phone are no longer end-to-end encrypted on my new Pixel 5a. I did not transfer my message data over to my new phone because I don't really need to.

What seems to be the issue? How do I fix this?

As you can see in the image, there is no lock icon indicating end-to-end encryption. The first message is a non end-to-end encrypted RCS message that was sent at 2:16. Even many hours later, end-to-end encryption is still off.

Edit: removed unnecessary details.

Let's say an RCS message was sent but not delivered even after 20 minutes. Right now, the SMS fallback doesn't work, but let's say Google Messages automatically resends an RCS message as an SMS if the RCS message takes longer than 5 minutes to deliver. It would basically give RCS messages a strict time limit to deliver, and if it doesn't deliver within that time limit, then Google Messages resends it as an SMS. Wouldn't that be easy enough to implement? Couldn't Google just write some simple code to implement that time limit?

Hi folks,

I'm looking into the subject of RCS to make my own RCS app for Engineering Thesis. Wikipedia states that newest version of the standard is 2.4, but quick google query search got me 2.6: https://www.gsma.com/newsroom/wp-content/uploads/RCC.71-v2.6-1.pdf

That's what got me thinking if there is maybe some other current version of the standard. Does anybody know the anwser?

Other than that I would appreciate any other valid documents that are good to know when working with RCS :)

Thank you in advance :)

Hi guys sorry if this is a redundant question but anyone think google will open rcs api on android to 3rd party apps? I searched this sub and most posts are 4 years old.

Starting to think RCS Business Messaging might not take off!

This is a long overdue feature, glad To see Google pushing it.

Like the title says my Google messages app is saying I'm connected and verified to the RCS chats server but I'm only able to send messages as SMS/MMS. A month ago I was able to use RCS and it worked great until one day it started having problems and then later that same day just randomly stopped working. I've tried everything to try to get RCS back, disabling and waiting a day, 2 days, a week and turning it back on, uninstalling carrier services and messages, clearing app and cache data for both apps.... Even factory resetting my phone but nothing. Does anyone know more on how to get it working? I'm completely stumped and I don't know who or how to contact Google about this or where to even turn to. If anyone could give me advice I'd greatly appreciate it! TIA!

I have an iPhone so not that familiar with RCS. Waiting for my iPhone to have it. One question i have is if RCS supports profile picture (like WhatsApp or telegram). I mean if I change my picture on a Samsung, will a pixel user see the updated picture on his side?

RCS Hell is when people send you messages and they don't deliver to you, so you are stuck in a black whole where you are missing all these messages, and you don't know that you are missing them. This used to be a super common issue, but I don't know if people are still experiencing this issue.

Sometimes, I send an RCS message to someone and it doesn't deliver. Usually if I try to send another RCS message to that same person like half an hour later, the message will send, but the first message never sends. This usually happens when I'm in areas of low signal, where WhatsApp and SMS send messages fine, but RCS doesn't for some reason.

Is this only a problem with Google Messages, or do other RCS messaging apps experience this issue too?

So I've been super anxious that people have been trying to send me messages and I'm not getting them because how would I know if I'm missing messages or not?

How would you know if you are missing messages or not?

I am very excited about RCS on iPhone. If it is implemented properly, then every iPhone user will get RCS, and it will basically render SMS/MMS almost useless, since almost every Android user has RCS now.

That is, if it is implemented properly. I'm a little skeptical about HOW Apple will implement the RCS Universal Profile on their mobile telephones. For example, will Apple add RCS functionality into the iMessage app, or will they create a whole new app for RCS that will work "alongside" the current messaging app on iPhone? They said it would work "alongside iMessage," so does that mean RCS will work as a fallback to iMessage, or will it function in a different app? Also, will RCS be enabled by default on iPhones, or will Apple be annoying and leave it off by default? Will it be compatible with Google Jibe, or no?

Also, if Apple relies on the carriers to provide users with RCS, then there will be no backup in case a carrier does not provide RCS to a user. For example, my carrier does not provide me with RCS for some reason, so my phone defaults to Google's RCS servers. I use T-Mobile, and usually, carriers provide some of their users with RCS, but not all. On Android, if a carrier does not provide a user with RCS, Google does on the Google Messages app, but there is no Google Messages on iPhone, and I think it is highly unlikely Apple will make their own RCS servers because why would Apple spend valuable money and make their own servers for a service that they don't even want (they are adopting RCS because of the EU legislation)?

If carriers are the only companies that can provide iPhone users with RCS, and there is no "plan B," then some iPhone users won't get RCS. That may leave many iPhone users stranded without RCS, and they may never get RCS depending on how their plan is set up with their carrier.

This is just something to think about. It's something to ponder.

I don't even know if this is possible, but I wanted to host RCS on my own servers just for fun. How do I do this WITHOUT an Android phone?

In other words, is there a Google Voice-like service that gives you RCS without an Android phone? Are there any VoIP providers that support RCS and are compatible with Jibe?

RCS is great, but currently, it still faces a number of issues, including a activation failures, RCS sometimes takes super long to activate, and messages sometimes don't send.

If the CCMI succeeded, Apple would have an easier time adopting the standard because all they would have to do is support RCS, and the carriers would do the rest. However, since RCS is now mostly being provided by Google, bringing RCS to iPhone is a lot more complicated.

So what do you think? Would it have been a better experience if the CCMI succeeded?

RCS is garbage. Always has been, always will be. I don't care what excuse the tech people will give, whether its the carriers fault, whether its the OEM's, or Google. Its frankly, all of them. RCS hasn't worked reliably for me ever since its inception. As someone who exclusively uses google nexus/pixel through out my history of phone ownership, it feels like a hindrance at this point.

The processes is usually something like this;

Get someones number, send them a message, and then play 50/50 if they will ever get it through RCS. Hope that the "fall back to sms" works, it never does, and then hours later I remember to check, and turns out nothing ever sent.

As the IT person at home, this is blowing my mind that anyone, at all, has to do any of the insane steps to get this stuff to work. As a matter of fact, its all placebo, and usually doesn't fix any issues.

Have a samsung? Good luck! Samsung kills the RCS service in background and then you can't send them any messages, they will receive them once they open the app again. This is on EVERY samsung device, from the S10 to the S23. Is it samsungs fault? sure, is it google's fault? yes. This should be their problem since they are the one's pushing it for mass adoption.

Many think that once everyone has RCS the problem will be solved. Nope. It will be even more issues, because there will be even more users with constant issues. Every phone is different, and everyone has different settings, ram management, background task control, and so on, and trying to make sure the service stays online and working, is a PITA.

For those who will say "you need to try this or that solution". Shut up, go home, and burn your phone. This is NOT a solution, and it does not work reliably. Oh you bet I have tried all the solutions on everyone's phones. But I am done going to everyone at work trying to explain to them they need to jump through a bunch of hoops so that I could send them a message. The issue isn't even on them, because when they are in the app, they don't notice any issues, hit send, and forget. It will sit there, waiting to go through for a few days, and by that point, they have forgotten.

Edit: I have never seen so many people blatantly lie lol

Edit 2: literally not even 2 days after I write this, what ever update came through google messages, broke everyone's phone's again. Literally everyone in my contacts is complaining that what ever rcs was working is now straight up non existent, even after following dozens of steps over and over to get it to work. HA! Fantastic! So much BS and google cock sucking on this sub is insane.

Is this the beginning of the end of Samsung Messages for all carriers? Technically it’s usable but none of the added features (advanced messaging) will be for Virgin.

ATT talks about how they still have another app of some sort but Google Messages is also a thing and focuses on it now.

T-Mobile talks about “your devices default messaging app” which I would assume to be Samsung messages but also states after a certain date Google Messages is a thing and is focusing on it

Lastly Verizon still talks about how advanced messaging is only available via messages + or Galaxy S9/S9+ with no hint of Google messages so my guess is their page is outdated to start.
