WhatsApp introduced delete for everyone feature last year. The feature is available only for iPhone users and it can be enabled or enabled WhatsApp > Settings > Chats > Save to Camera Roll. The problem is that if a user having this feature enabled then automatically images will get saved in the devices Camera Roll and it cannot be deleted. The issue is more sensitive in the case of Whatsapp group’s that contains both iOS and Android users. If user A shared a confidential photo in the group, later he deletes the message using deleted feature it works only for Android.”]
