May 18, 2018 · Then I disabled Airplane Mode Switch once more in device manager and restarted the computer. I am permanently no longer able to use the switch to toggle airplane mode. To locate your driver for Airplane Mode Switch, go to Device Manager -> Human Interface Devices -> Right Click Airplane Mode Switch -> Properties -> Driver -> Driver Details. I switched my iPhone 8 into airplane mode, but it continued periodically transmitting on 1.8 GHz, as measured by an electrosmog meter. Why? Isn't airplane mode supposed to turn off the radio transmitters? Or is airplane mode on an iPhone only a low-power mode? After enabling airplane mode, I powered the phone off and booted it in a Faraday cage.
