Why can't I delete text messages on the POCO C75?

Deleting text messages keeps your messaging App organized, protects your privacy, and frees up storage space.
If you are unable to delete messages on your POCO C75, you can try the following troubleshooting steps:
1. Some messages are stored on the SIM card or as service messages (e.g., carrier notifications) and can not be deletable. Try deleting messages stored in the phone memory.
2. Verify App permissions. Go to Settings >> Apps >> Message and ensure the App has storage and SMS permissions.
3. Open Settings >> Apps >> Message >> Storage >> Clear cache to remove temporary data that can block deletion.
4. Restart the phone. Sometimes a simple reboot resolves temporary system glitches.
5. If the issue persists, updating the system software can help resolve deletion problems.
