Delete a Single SMS or Message auf Huawei
Messages on a Huawei phone are grouped into conversation threads by contact or number. Deleting the whole thread is fast, but it removes every message, including ones you still need for reference.
To keep the rest of a conversation intact, you can remove a single entry instead. This is useful for removing a wrong recipient message, an outdated code, or a message sent by mistake, while keeping the surrounding chat history readable.
Steps
Open Messages ➔ Tap on a conversation ➔ Tap and hold the message you want to delete ➔ Tap on delete ➔ Confirm with Delete
Tapping and holding selects only that message, not the whole thread. A confirmation step follows so you cannot remove it by accident.
Once confirmed, the message is gone from the thread on this device only. It does not notify the other person and does not remove the message from their phone.
If you want to clear an entire conversation instead, use the delete option on the conversation list rather than inside the thread.
