What happens when a contact is blocked in WhatsApp on a phone - briefly?

When a contact is blocked in WhatsApp on a phone, the blocked user will no longer be able to send messages or calls to the blocker, and their messages will not be delivered. Additionally, the blocked user's status updates and profile picture changes will no longer be visible to the blocker.

What happens when a contact is blocked in WhatsApp on a phone - in detail?

When a contact is blocked in WhatsApp on a phone, several changes occur that affect both the user who initiated the block and the blocked contact. Here's a detailed breakdown of what happens:

For the person who blocks the contact:

  1. Messages: Any messages sent by the blocked contact will not be delivered and cannot be seen by the blocking user. The sender will see only one checkmark (indicating message sent but not delivered).
  2. Calls: Voice and video calls from the blocked contact will not go through. The call will show as failed on both ends, with no ringing or missed call notification for the blocking user.
  3. Status Updates: The blocking user will not see any status updates (text, photo, video, or GIF) posted by the blocked contact.
  4. Profile Picture and About Section: The profile picture and 'About' section of the blocked contact will no longer be visible to the blocking user.
  5. Group Messages: If the blocked contact is part of a group with the blocking user, they can still send messages to the group. However, the blocking user won't see their messages in the group chat.
  6. Notifications: The blocking user will not receive any notifications about the blocked contact's activities or presence.
  7. Last Seen and Online Status: The blocking user cannot see the 'last seen' timestamp or online status of the blocked contact.

For the blocked contact:

  1. Messages: Messages sent to the blocking user will show one checkmark (indicating message sent but not delivered). They won't be able to see their messages in the chat window with the blocking user.
  2. Calls: Voice and video calls to the blocking user will fail immediately, showing a 'call failed' notification. There won't be any ringing or indication that the call was even attempted.
  3. Status Updates: The blocked contact cannot see the 'last seen', online status, profile picture, or 'About' section of the blocking user.
  4. Notifications: They will not receive any notifications about the blocking user's activities or presence.
  5. Group Messages: While they can still send messages to groups that include the blocking user, their messages won't be seen by the blocker.
  6. No Indication of Being Blocked: WhatsApp does not notify users when they have been blocked. The blocked contact will see no changes in the chat interface, except for undelivered messages and failed calls.

These measures are designed to protect users' privacy and prevent unwanted communication. However, it's important to note that blocking a contact on WhatsApp does not remove them from your phone's contacts list; it only affects their ability to communicate with you through the app.
