When you block a contact on WhatsApp, what happens - in detail?
When you block a contact on WhatsApp, several changes occur in your communication with that person. Firstly, the blocked contact will no longer be able to call or message you through WhatsApp. Any messages they send will not be delivered and there will be no notification for you regarding these undelivered messages. Similarly, if the blocked contact tries to call you, the call will not go through and they will see a message indicating that your calls are being forwarded.
For you, the experience is also altered. You will no longer receive any messages or calls from the blocked contact. Their messages will not appear in your chat list or notifications. Additionally, you won't be able to view their last seen or online status, nor will you see any updates they make to their profile picture. Essentially, all communication channels between you and the blocked contact are severed.
It is important to note that blocking a contact does not remove them from your contacts list on your phone. They remain listed, but with no interaction possible through WhatsApp. Furthermore, if you were part of a group together, you will still see their messages in the group chat, and they will continue to receive your messages in the group as well. However, they won't be able to call or message you privately outside of the group.
Blocking a contact is a significant action that affects both parties involved. It essentially stops all real-time communication through WhatsApp, maintaining privacy and limiting unwanted interactions.
