Blocked Phone Numbers Samsung [upd] -

Furthermore, the technical design of the block feature raises questions regarding transparency and closure. When a blocked number attempts to call a Samsung device, the caller typically hears a message stating that the recipient is busy or unavailable, followed by the option to leave a voicemail. This design choice is deliberate: it prevents the blocked caller from knowing definitively that they have been blocked, which can prevent escalation in volatile personal situations. However, the fact that blocked callers can still leave voicemails is a significant loophole. A user blocking a stalker or an abusive former partner may still be subjected to harassment if they accidentally check the "Blocked" folder in their voicemail or messages app. Samsung mitigates this by hiding these messages by default, but the option to view them remains, requiring discipline from the user to avoid re-exposing themselves to the content.

To block all unidentified callers, toggle the switch for to on.
