Why is my iPhone 15 Pro Max missing the call decline option?

If you want to decline an incoming call, simply double tap the side power button and the call will be sent immediately to your voicemail. I don't recall ever seeing a decline a call message, but you should see a red button, which will also decline the call.

Do you mean have your phone send a message to a caller if you can't answer your phone?

If that's what you meant, see this --> Answer or decline incoming calls on iPhone – Apple Support (UK)

Sorry, on the locked phone. If it’s unlocked you see the red button

Same for me: can’t cancel the incoming

calls, when the screen is unlocked and the call is coming. Neither pressing nor double pressing power button help. Have to wait till the call stops 🤦‍♂️ iPhone pro max 15, ios18

yes that's right. I'm guessing maybe a bug from ios18?

It works fine for me using iOS 18.
