Follow these steps if you want iMessage like experience for your Android “Messages” App.
Prequisites :
- Latest Google Messages beta version. Either from the Play Store or APKMirror.
- Activity Launcher
Steps:
- Turn off WiFi.
- Open the Activity Launcher app.
- Tap the dropdown up top and switch from “recent activities” to “all activities.”
- Scroll down to find “Messages.”
- Tap on it and find the “Set RCS Flags” activity. Select it to open the hidden RCS configuration settings in Google Messages.
- Select the dropdown under “ACS Url” and select the ‘http://rcs-acs-prod-us.sandbox.google.com/’ option.
- Go home and clear Messages from your recent apps list. Open it back up and you should see a message at the bottom asking you to set up Chat. Accept it by tapping on “upgrade now.”
- After starting setup, re-enable WiFi and wait a few minutes. If successful, go to Settings > Chat features and it should say “Status: Connected” up top.
Troubleshooting :
If that didn’t work for you, then try these additional steps:
- Go to Settings > Apps and find “Carrier Services.” It’s a system app, so you’ll need to tap on the overflow menu and select “show system apps.” Once you find it, clear data on the app.
- In Settings > Apps, find Messages and force stop it.
- Repeat steps #1-6 from above, but while you’re in the RCS configuration settings, expand the OTP Pattern dropdown and select ‘Your\sMessenger\sverification\scode\sis\sG-(\d{6}).’
