Vulnerabilities of modern phones 

• The phone can be intentionally, or covertly, ‘off-hook’ during important conversations and negotiations

• Voice recording software can intentionally, or secretly, run on the smartphone

• Listening software can run in a ‘stealth’ mode

• Spyware can be installed on the smartphone without the owner's knowledge, allowing attackers to activate covert eavesdropping around the phone.

• Smartphone apps which have access to the phone's microphone can be used for eavesdropping in cases of them having been hacked (usually messengers or social network apps) There are known cases of transmission of such software by exploiting the vulnerabilities of some messengers.
