A user complains that he can no longer see any wireless networks, connect to his bluetooth headset, or make phone calls on his Android phone. Which of the following options would best address these issues?
These symptoms describe a phone that is in airplane mode. The best option available would be to disable airplane mode. On most smart phones you could also re-enable WiFi and keep Airplane mode.
Airplane mode, aeroplane mode, flight mode, offline mode, or standalone mode is a setting available on smartphones and other portable devices When activated, this mode suspends the device's radio-frequency (RF) signal transmission technologies (ie, Bluetooth, telephony and Wi-Fi), effectively disabling all analog voice, and digital data services, when implemented correctly by the electronic device software author When cellular phones became prevalent in the 1990s, some communication headsets of aircraft pilots would register an audible click when a cellular phone on the aircraft would transceive a signal This clicking on the headsets became overwhelmingly distracting to airframe control, with more and more phone calls from airplane passengers as time went on
