title: Android: does flight mode turn off radio completely or just transmission portion?
body: <p>I have an Android application that uses both ble and wifi.  Periodically ble locks up and no longer detects devices.  while fault-finding the lock up, I noticed that I can reestablish normal operation by switching flight/airplane mode on an off.  BUT if I turn bluetooth on/off or wifi on/off, or both wifi and bluetooth on/off, I cannot replicate the results I get by turning flight mode on/off.  This tells me that flight mode is doing something different.  So:</p>
  
  <p>what is the difference between flight mode and the separate functions for turning bluetooth and/or wifi on and off?</p>
