The answer to this question is both yes and no. In some cases, it is possible to delete WhatsApp messages from someone else’s phone, but in other cases, it is not possible. The ability to delete messages from another user’s phone depends on a few factors, such as the type of phone being used and the user’s settings.
If both users are using an Android device, then it is possible for one user to delete a message from the other user’s device. This can be done by accessing the other user’s phone and going into the WhatsApp settings.
From there, the user will be able to select “Delete for Everyone” which will delete the message from both phones. This feature must be enabled in order for it to work.
If one of the users is using an iPhone, then it is not possible for one user to delete a message from the other user’s device. This is because Apple devices do not allow third-party apps (such as WhatsApp) to access their settings or data.
In addition, if either user has disabled “Delete for Everyone” feature on their device, then it will not be possible for one user to delete a message from another user’s device. Even if “Delete for Everyone” is enabled, if too much time has passed since sending the message then it will no longer be possible for one person to delete a message from another person’s phone.
Conclusion:
In conclusion, in some cases it is possible for one person to delete WhatsApp messages from another person’s device but in many cases this isn’t possible due to various factors such as type of phone being used and settings on each device. It’s important that all users have “Delete for Everyone” enabled if they wish for this feature to work.
