Turn Deletion Sound On or Off auf Oppo
The deletion sound on Oppo phones is a short audio cue that plays when you delete a message, notification, or similar item. It works as an acoustic confirmation, comparable to the keyboard click or the screenshot sound, and it is controlled by a single system-wide switch rather than a setting inside each app.
Because the toggle sits under the general sound and haptics settings, it is easy to overlook, and a system update can occasionally reset it to its default state. If you notice the sound suddenly missing, checking this switch first is faster than assuming a bug.
Where to find the setting
Open Tap on Settings ➔ Tap on Sound & vibration ➔ Tap on More sounds & haptics ➔ Enable or disable Deletion sound. Flipping this switch on plays the confirmation tone every time you delete something; flipping it off removes the sound completely.
The change takes effect immediately and does not require a restart. It also does not affect other notification sounds, ringtones, or media volume, since those are managed separately in the same sound menu.
