Why don't messages delete for everyone in WhatsApp, only for me - briefly?

Messages in WhatsApp do not delete for everyone due to the nature of how messaging systems function. Once a message is sent, it is immediately delivered to the recipient's device, making it impossible to recall universally. Only the sender can delete messages from their own view and the chat history on their device.

Why don't messages delete for everyone in WhatsApp, only for me - in detail?

When a user deletes a message on WhatsApp, the intent is to remove it from all parties involved in the conversation. However, users may notice that while the message disappears for them, it remains visible to others. This discrepancy arises due to several factors:

Firstly, WhatsApp employs end-to-end encryption, ensuring that messages are secure and can only be read by the intended recipients. When a user deletes a message, this action is recorded on their device but not necessarily communicated instantly or effectively to other devices in real time. As a result, the deletion might not synchronize immediately across all participants' devices, leading to a delay in the message being removed from others' screens.

Secondly, network connectivity plays a crucial role in the timely deletion of messages. If the sender or recipient has poor internet connectivity at the time of deletion, WhatsApp may not be able to promptly update the status of the message on all devices. Consequently, the message will remain visible until the device regains a stable connection and updates the chat history accordingly.

Additionally, the version of WhatsApp being used can influence the effectiveness of message deletion. Older versions of the app may not support real-time synchronization as efficiently as newer ones. It is essential for all participants in the conversation to have the latest update installed to ensure seamless communication and immediate reflection of deletions across all devices.

Moreover, user settings can also impact the visibility of deleted messages. If a recipient has enabled read receipts or data saving modes, these settings might affect how quickly they receive updates about message status changes, including deletions.

In summary, the asynchronous nature of communication in WhatsApp, combined with factors such as network connectivity, app versions, and user settings, contributes to the delay in message deletion across all devices. Understanding these underlying mechanisms can help users better manage their expectations regarding the immediate visibility of deleted messages on WhatsApp.
