There is no way to remove someone from a WhatsApp without notify them. Since the group chat history is available in their chat list, the information will be notified there when he/she is removed from the group and will be notified to every other member in the group too. However, there will not be any special push notification message or an alert sent to that person or other group members.
But the group chat list will not be deleted from their WhatsApp. The list will be there with all the previous messages, but the person will not be able to type and send any message to the group or cannot see any new messages. The chat will also show a small message saying ‘You are removed by (member name, who removed you)’.
But of course, if you are removing someone from a group which not at all active, then that person and any member in the group will know about the removal until they check the group chat. Once they open the chat they can see a small notification within the chat. But one thing, if the group is flooded with so many messages after the removal, then it is difficult to find that notification. However, the removed person still has the chat history on his/her phone.
So whenever they open the chat, they can see that notification. Since the removed person will not get any new message further and they can see the notification there. They can see the message ‘
The only option available for them is to read the chat or to delete the entire chat.
As i mentioned in my different post regarding the hidden features of WhatsApp, the company is adding more features all the time since WhatsApp is now the primary messaging application for all mobile phones. Also, this is one of the most requested features, so we may hope that WhatsApp may include these features in their future update.
Recently we noticed that WhatsApp is including some features that users are constantly requesting. For example, even after adding the group call feature in their application. Users are complaining about the issue that, the option to make a call from the group chat window is now available.
Now, WhatsApp now fixed it by adding a call button in the group chat and the feature and started rolling out to the users which make that feature more useful and easier. So in the same was this feature also expected to be updated more effectively. We will update that when it is released.
