Oppo: Turn Off Vibration When Answering or Ending Calls

Oppo phones running ColorOS trigger a short vibration whenever a call is answered or ended. This is separate from your ringtone, incoming-call vibration and Do Not Disturb rules, so muting the ringer or switching to vibrate-only mode does not remove it.

The pulse comes from a dedicated toggle inside the calling settings. It exists as a tactile confirmation that a call connected or disconnected, which is useful if you often answer calls without looking at the screen, for example while driving or with the phone in a pocket.

To change it, open Phone ➔ Menu ➔ Settings ➔ Calling accounts and find the entry for vibration on answered or ended calls. Switch it off if the buzz feels redundant, or turn it back on if you rely on the feedback when you cannot see the display.

This setting only affects the confirmation vibration for answering and ending calls. Incoming-call vibration, notification vibration and system haptics elsewhere in ColorOS are controlled separately and stay untouched.
