Reject an Incoming Call auf Oppo
On an Oppo phone running Coloros, an incoming call shows a green phone icon in the center of the lock screen. Unlike some other Android skins, there is no separate red decline button next to it.
To reject the call, place your finger on the phone icon and drag it downward. Releasing the icon after the drag rejects the call and sends the caller to your carrier's standard call handling, usually voicemail.
The Menüpfad for this gesture is Drag the Phone icon down ➔ Release the Phone icon to reject the call. If you release the icon too early or drag it in the wrong direction, the call keeps ringing and nothing happens, so you get a second chance to try again.
When this gesture is not enough
If you need to reject calls without any gesture at all, for example while the phone is in a pocket, check your ringtone and do-not-disturb settings instead. Those control whether the phone rings in the first place, while the drag gesture only handles a call that is already ringing on the screen.
Accidentally answering calls usually points to dragging too short a distance rather than a broken screen. Practicing the full downward drag a few times on a test call is often the quickest fix.
