A clear and concise description of what the bug is.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

**Expected behavior**
A clear and concise description of what you expected to happen.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**System**
Android Version: [e.g. 10]
Custom ROM: [e.g. LineageOS 17.1]

**Additional context**
Add any other context about the problem here.

Start by reviewing the microG source tree and its AndroidManifest.xml, focusing on the proposed org.microg.gms.rcs.RcsService and CarrierService entry points. Verify whether the reported Google Messages RCS failure is reproducible before evaluating the suggested Shizuku and ADB setup. Done would require a validated implementation and working RCS registration on the stated Android setup.
