As with all end-to-end encryption it stops at the "end". It is this unencrypted state, in which humans consume data, that can't be defended by crypto.
Therefore the only way to be completely safe, is to make sure both you and your conversation partner don't decrypt their message until it's on an offline device only you have access to.
But end-to-end encryption where the interface (mobile app/phone) is controlled by the parties you want to protect your data from is not possible. WhatsApp could send freaking screenshots back of the unencrypted data if they wanted. For nearly all other threat models whatsApp's encryption is a wonderful add-on.
