Simply clicking the "delete" button inside a chat is not enough if you want the contact to disappear forever. In this article, we will analyze in detail the algorithm of actions specifically for the model Samsung A50, taking into account the features of the shell One UI.

There is also a difference in deleting through the interface of the application itself and through system settings. In new versions WhatsApp it has become possible to delete contacts directly from the chat information menu, but this functionality may not work correctly if data is out of sync.
