::This only shows DM is a non-important puppet person. The russians are totally paranoid people, some military radios still use hand-keyed morse code with printed one-time key pads for utmost security with regards to nuclear weapons. They would never trust important cellphone talk on an unknown device, which can be hacked due to its computer operating system. Putin definitely uses nothing but FSB-approved comms gear (even if just calls for two bottles of beer, that can be an important info for eavesdropping spies).
