When duplicate messages are appearing in Rhinogram it's caused by the carrier (AT&T, Verizon) Rhinogram is attempting to interface with. When your device is in a low coverage area (or it disconnects to the network), the device or network may try re-delivering messages as it reconnects. This results in sending or receiving duplicate text(s). 

Your contact's phone could also be the one doing this. There's not much we can do if that's the problem, but there are some other things we can try to fix: 

1. If receiving duplicate messages, check if the duplicated messages are coming from multiple senders or just from one. If they are from one sender, ask the person if they sent the messages more than once (even by accident).

2. Restart the device.

3. Turn off Wi-Fi to ensure you're using the carrier's network.

4. Check your device has enough free storage space. Most carriers recommend having at least 15% of the on-device storage free.

5. Uninstall any downloaded messaging apps. Some of these can cause double texts.

    For Android devices, clear the app cache and data of the Messaging app.

    For Apple iPhone:

  • Turn off Repeat Alerts (Settings > Notifications > Messages > Repeat Alerts > Never)
  • Turn off iMessage, and then turn it back on (Settings > Messages > iMessage)
  • Reset Network Settings (Settings > General > Reset > Reset Network Settings)



If problems continue, delete messages and message threads (on the contact's phone). You can back these up beforehand using apps from the app store.

If text messages continue to duplicate, contact your carrier to report the issue so they can check your network area.
