Research direction

Start by reproducing the reported failure in the conversation send flow on Android 13, then trace how SMS/MMS send failures are surfaced and recorded. Done means identifying why sends fail for specific contacts and verifying successful sending to those contacts while confirming incoming messages still work.

Android 13

Steps to reproduce the bug

At some point, the app completely loses the ability to send SMS/MMS messages to specific contacts. When attempting to send a message, it fails, but I can still receive incoming messages from those exact contacts without any issues (one-way communication).

Expected behavior

Messages should be sent and delivered successfully to all contacts, as long as the network connection is stable and incoming traffic works.

Actual behavior
  1. Open a conversation with a specific contact.
  2. Type a message and hit send.
  3. The message fails to deliver.
  4. Have the same contact send a message to me — their message is received successfully.
