Turn Outgoing Message Sound On or Off auf Huawei
Huawei's Messages app plays a short audio cue every time a text leaves your device. This confirmation sound is a built-in notification feature, separate from your ringtone or general media volume, which is why muting your phone does not always silence it.
The toggle for this sound lives inside the app itself. Open Messages, then open the menu, and go to the settings. There you find the option to activate or deactivate Hear outgoing message sounds.
Switching it off stops the tone for every sent SMS or RCS message, regardless of the recipient. It does not affect incoming message alerts, call sounds, or keyboard clicks, since those are controlled by separate settings.
If you only want silence during specific hours, a system-wide Do Not Disturb or Focus mode is often a better fix than disabling the sound permanently, since it also covers calls and other notifications at once. Turning off the outgoing tone here is the right move if you simply find the send confirmation unnecessary in daily use.
