There are certain security/privacy issues regarding Whatsapp which needs to be amended. Netizens who are using GB Whatsapp (or any similar unsafe apps) from unverifed source can see the deleted msgs/deleted status. It's obvious that Whatsapp isn't responsible for this but I would like to request the developers to see into the matter and try to fix these vulnerabilities because it is a great security/privacy bug for the users.. Thank You!
