  • Using RCS with Google Messages on GrapheneOS

Try these steps again but reinstall the latest version of the messages app. Also reinstall the Google app that needs to be working first As I believe messages uses the app intially

Make your place services is set up correctly and then reinstall the Google app, set that up, and then set up messages. Make sure you're getting Google and messages through the play store

I've tried the method granting permissions with Shizuki, installing Google app, installing carrier services, and toggling Wi-Fi on/off among other things with no luck. Anyone else have any other suggestions? I'm on U.S. Mobile (Verizon network). Seems like Verizon is the problem carrier most of the time when enabling RCS

    kyle just to confirm, did you toggle the automatically verify phone number option in the sandboxed google play settings as described above as well as give sms, notifications, and network permissions to play services, google Messages, and the Google app?

      Sbpr Yep, I did toggle automatically verify phone number, and gave those permission to Messages, Google app, Google Play Store, and Google Play Services

      Anyone able to get this working on AT&T in the US? I have done these steps above on my old Pixel7 and new Pixel8 with no luck. I did confirm that RCS worked when I reverted my 7 to stock and the 8 before installing GOS. I installed carrier services but it doesn't seem to ever run.

      Edit:

      • Gave play services notification, SMS and network.
      • Installed google app and gave it the same
      • Installed messages and gave it same.
      • Tried installing carrier services
      • Check permissions in App Ops for messages "read device identifiers perm (already had it)
      • Checked Google settings for auto phone number validation
      • added number to the SMS settings buried in messages app
      • Someone mentioned changing number in sim settings. I couldn't find that but verified my number was right in SIM info.

      1. Install Play services.
      2. Install Google Messages and disable RCS in the app
      3. Give SMS, phone, contact and network permissions to Google Messages
      4. Give Network, phone, SMS permissions to Play Services.
      5. Install Shizuku and app opps. Enable wireless USB debugging with Shizuku.
      6. Force close Messages and Play Services and clear cache.of both.
      7. Give the read device identifiers permission to Play Services.
      8. Open Messages, enable RCS. It will connect in minutes (I would say max 1h).
      9. You can remove device identifiers permission to Play Services and uninstall App Opps and Shizuku.

      It disconnected after a few weeks. Do the trick again and it will reconnect.
      I did not touch any setting in the Google settings in the parameter.

        83639273 Wow it worked! I missed the device identifiers for play services. Thank you so much!

        Edit. Well it said it was connected but wouldn't actually send an RCS message. Hum...

        I shut it off and back on and it connected again. But none of my messages are sent as RCS. More digging to do! However a very positive step in the right direction! Thank you again!

          After adding back the phone number in messages advanced, clearing cache for messages and restarting the phone it started sending RCS messages. Thanks to all.

            FYI: I did have issues after taking away "read device identifiers" from play services and it started working again after giving that permission back.

            Me too
            It was the same at the beginning
            Just wait a bit and it will work

            9. Very important step : donate to GrapheneOS

            You can remove the device identifiers, SMS and phone permissions to Play Services and uninstall App Opps and Shizuku.

            It disconnected after a few weeks. I did the trick again and it reconnected.
            I did not touch any setting in the Google tab in the settings.

              You're steps worked for me.
              I followed everything, then I cleared cache in messages and rebooted. (cap9qd )
              In addition, after rebooting, I also turned off developer options.
              Unless, someone can give me a reason why I shouldn't, I'm going to leave SMS and phone permissions ON in Play Services for a few weeks and see if RCS disconnects.

              Thanks everyone. Now let's see if it lasts.

                I was able to get RCS to work. I was missing adding my phone number in the messages app. I went into settings, advanced and put my phone number in which allowed it to work

                83639273
                This worked! Had to clear cache and reboot but I am connected and sending with RCS. Anything wrong with leaving Device identifiers on with Play Services?

                  83639273 Thanks! This also worked for me (Pixel 8 Pro on T-Mobile USA). Worked straight away after a reboot.

                  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

                    83639273 Followed all the steps, on a new Graphene install, and it says "RCS chats aren't available for this device."

                    After a reboot I was able to enter my number but it just shows status as "Setting up....."
