## The story

When an iPhone rings, the interface changes depending on whether the device is locked or unlocked. A locked screen displays only a slide‑to‑answer control, while an unlocked screen offers both answer and decline buttons. The decline option appears in a compact banner or across the full screen, but it is always present when the phone is unlocked. If a user wants to reject a call without using the on‑screen button, they can double‑tap the side button to send the caller straight to voicemail. Alternatively, pressing either volume button silences the ring without declining the call, regardless of the screen’s lock state. iPhone also provides a Message option that lets callers receive a text instead of a voicemail, with several pre‑set replies or a custom message. These replies can be edited in Settings > Phone > Respond with Text, allowing users to quickly explain why they cannot answer. For persistent spam or unknown callers, the Screen Unknown Callers setting offers options to silence, ask for a reason, or block the number entirely.
