Jinli mobile phone encrypted information with chip; Will someone steal your mobile phone?

Hello, ordinary telephones and messages are easy to be stolen, but if they are private telephones and messages, they will not be stolen. The call content using the special line call function is encrypted from the hardware (a mobile phone, an encryption chip, a call, a key); However, both mobile phones must have the function of "private line call", which is currently only supported by M6/M6Plus.
