  • Using RCS with Google Messages on GrapheneOS

You could switch carriers but I would first turn off RCS in messages, deregister your number with Google for RCS them re download the messages app allow permissions and retry RCS. You seem like from your post you have everything set up , so I would try what mentioned and let it cook for a bit

epileptic055 I'm having the same issue. I've done ALL the steps above, granting all the permissions including Read Device Identifiers, tried uninstalling/deleting appdata for messaging and all the google apps, restarting, redoing the whole process, multiple times.

Messages setting says RCS is Connected, but it still only let's me send SMS to contacts I know have (stock) Pixels with working RCS. Even checking RCS Connection State in the app's Debug menu (enable it by typing *xyzzy* in the Messages search box) shows it as connected, with the correct ACS url and everything. I'm really at a loss of what else to try...

OfflinePuffin Thanks I unregistered and put my number in the website from the disable-chat. I think uninstalled the messages app and re-installed it and RCS was enabled. I tested with my samsung phone RCS appears to be working. I removed carrier services and using app ops set most of the play services to ignore and everything seems to be working.

I didn't need to give Play Services more privileged access to get RCS to work. I guess it is because my carrier has native support. A bit ironic because they don't support VoLTE/WoWiFi on Pixel phones yet.

I don't want to give Google more data, but I also think SMS should be deprecated and every messaging app should be compatible with RCS even if they prioritize their own implementation (similar to iMessage).

Dealing with this a few months ago on my P8P when I could not get graphene to remain RCS registered.

I switched to a P9P on release and kept stock Google for about two weeks before switching to Graphene and it has been working flawlessly. I have play services and messages installed, but no other google applications. No carrier services. I am using Verizon. Play has access to calls/SMS/contacts/phone.

Interesting that using the same phone number, Google account, and carrier can work on one device but not another.

Did anyone else get deactivated about a week after upgrading to Android 15?

I'm still active. Never changed anything after it began working a few months ago.

N7EKB Use ADB instead. You can download it here.

chenxiaolong I granted READ_DEVICE_IDENTIFIERS the old fashioned way via adb:

adb shell appops set com.google.android.gms READ_DEVICE_IDENTIFIERS allow

The state of the permission can be found with:

adb shell appops get com.google.android.gms | grep READ_DEVICE_IDENTIFIER

Previously, I had:

READ_DEVICE_IDENTIFIERS: deny; rejectTime=+2m21s554ms ago

After enabling the permission, I have:

READ_DEVICE_IDENTIFIERS: allow; time=+47s616ms ago; rejectTime=+7m4s585ms ago

I would like to add something that might be useful in case someone struggle to activate RCS on GrapheneOS.

First I deactivated RCS on the phone (or Stock OS) used previously.
I then unregistered on the Google website.

After,
I have made all the requirement about giving identifier to play service (do it the "old fashioned way ®" with ADB on PC) and the permission needed to play service,

BEFORE,

installation of Google messages app.

Then I have installed Google messages app.

Then I give it the right permission BEFORE starting it for the first time.

Then I started it and went to the RCS activation which was straightforward and activated instantly.

In any case if you missed something you need to deactivate RCS in messaging app, uninstall it, reinstall it, give permission before first starting it, then activate RCS and hope for the best.

I tried for one week in various order to make sure I don't tell bullshit. I have achieved 100% success with what I have explained before.

Everyone keeps mentioning "Framework". Can someone please indulge me as to what app this is? I can't find it anywhere.

    I did a search on this page and could not find any mention. Are you having issues getting RCS enabled?

    Has anyone activated RCS on Mint Mobile? If so, did you need to grant READ_DEVICE_IDENTIFIERS or deal with any sort of carrier services app? It seems that each carrier has different requirements. I’d prefer not to grant that permission if at all possible.

      5rlyn That’s great, thanks for the response. Did you grant, Phone, SMS permissions to both Play Services and Google Messenger? It does sound like those are universally required.
