The notion that either WhatsApp, Signal, Telegram, or any similar messaging services have “un-breakable” encryption codes is bogus, and has been understood by tech experts for years :

Most national intelligence agencies that monitor threat communications -including NSA, CIA, SVR, MI6, and Mossad – use a simple work around that lets them hack Android and iOS devices and see what users are typing in before its converted to encryption. All these so-called secure apps know about this flaw, but keep it quiet so they can continue to attract users and build their market. And the biggest intruders on all these apps aren’t government spies, but commercial companies hunting personal info for advertising & other money making schemes.
There are NO unbreakable codes, no totally secure messaging, and no untraceable communications – Anywhere, any time.
