"I used to work on interfaces to all the computers on the latest 747 and the 787 and there is no wireless way to talk to any of the computers or sensors that have any input to controlling the airplane."
Don't they get weather data from somewhere? And if the pilot thought there was a thunderstorm or heavy turbulence in some direction, wouldn't they fly the plane through what appeared to be the clearest route on their own? (And does the autopilot not take weather into account?)
Yes, most (if not all) modern airliners have a radar dish in the nose of the aircraft. If you wanted to mess with this, you'd have to spoof radar echoes. Not something you can do from an android phone for sure.
"And does the autopilot not take weather into account?"
No, not in the slightest. Pilots adjust autopilot settings to account for weather. It is not automatic.
