Edit Quick Decline Messages auf Oppo
Rejecting a call with a quick text only works if the message actually sounds like you. Coloros ships with four generic replies, and many Oppo owners want to swap out lines like "Can't talk now. Can you call me" for something that fits family, coworkers, or friends better.
The quick response texts live inside the phone app settings, not inside the messaging app, which is why the option is easy to miss.
Tap on Phone ➔ Open the Menu ➔ Tap on Settings ➔ Tap on Quick responses ➔ Choose a Quick response ➔ Enter a Quick response and tap OK.
Each of the four slots can be edited on its own, so you can keep one for family, one for work, and rewrite the rest to match how you actually communicate. Changes apply right away and show up the next time you swipe up on an incoming call to decline with a text.
If the reply option doesn't appear when you decline a call, check whether your carrier or a third-party messaging app is blocking SMS auto-send, since that's a separate issue from the Coloros setting itself.
