Phone: Samsung Galaxy S10 (UK)
Version: OneUI 2.5 / Android 10
I've been using my phone in Samsung Messages with Chat (RCS) for months without issue. I could even send Chat messages to a friend who's using Google Messages. I didn't think this would work as I was using Samsung Messages, but it does.
I recently read that Google have finally added Scheduled messaging to Google Messages. So I installed it and was disappointed it doesn't have this feature yet, at least in The UK.
Since then Samsung Messages says it's connected to RCS (all seems fine) but I can tell it's not connected as that same friend and someone else I used to send Chat messages to now only give me the option to SMS.
I believe it's struggling to connect as from time to time it asks me to click the Accept button again to turn on Chat.
Google Messages connected to Chat the first time. But since going back to Samsung Messages, then back to Google Messages again, I can't get Chat to connect. In hindsight I shouldn't have Google Message's cleared app data but I wanted to be sure only one SMS app was active.
It's always constantly at Setting Up - Trying to Verify your number and never does.
Right now I'd prefer to use Samsung Messages until Google add scheduled messaging to Google Messages.
But ultimately I just want one of them to connect to Chat. I've been trying for 2 weeks now and neither will connect to Chat.
Thanks for the detailed reply. It looks like you echo much of my experience. Mine stopped working around 28/12/20.
I've not Factory Reset or contacted EE, Samsung or Google Support yet. Contacting support can be laborious. I've not factory reset as I'm unconvinced it's the phone and like you say it didn't fix it for you.
In Samsung Messages I was getting "Registration failed" but aren't now, but am happy it is failing as I know two contacts have RCS enabled and I'm only now offered SMS. Annoyingly in Samsung Messages the On/Off button has no visual indicator to say it's done anything.
Lots of new posts over on Google's forum too. I'm wondering if it's a larger issue Google haven't noticed/aren't letting on yet:
I've also never had a clear answer to how Samsung Messages interpolates with Google Messages?
Does Samsung app use it's own RCS Server, share Google's, is it something different. I know Samsung Messages relies on your carrier supporting RCS (e.g. EE UK does, Sky UK doesn't), whereas Google Messages it doesn't.
My phone was bought New from a Third Party site, not on EE firmware either.
I'm not sure as Google Messages won't connect though and it can be impossible to know for sure with Samsung Messages as there's no visual indicator to say whether the On/Off button is doing anything.
I know one of the two people has a Nokia 6 (Stock Android 9) with Google Messages on ID Mobile (which uses 3). I can ask this friend the next time I see him (will need to check myself, wouldn't be able to get him to check). The other is the man who serviced my boiler so can't ask him .
It would also be interesting to see if they can RCS Chat to me. I bet not as it has to register for other phones to know you have RCS enabled. I'll ask the first friend though for sure. Thanks.
If the phone tells you all is OK, there's a chance your 2 contacts may have RCS issues. Is it a great coincidence? Maybe not as some devices have this issue. Contact them and ask.
I saw my friend earlier and his Google Chat is still connected and I could messages with other people where Chat was connected. But for me it was SMS only as mine still won't connect.
So sadly nothing wrong his end.
