4) Did you know that Smartphones can save the rainforests?
Detecting chainsaws may sound like a novelty app, but it's a serious business: in Indonesia, the non-profit organisation Rainforest Connection wants to use donated Android phones to detect illegal logging.
As New Scientist reports: "The phones are outfitted with solar panels specifically designed to take advantage of the brief periods when light reaches the forest floor. Their microphones stay on at all times, and software listens for the telltale growl of a chainsaw, which triggers an alert."
5) Did you know that smartphones can be used as metal detectors?
The magnetometers built into many Android smartphones have surprisingly beneficial applications: as Medgadget explains, "Imagine having a metal detector handy when you, as an emergency physician, have an unconscious patient come in and you need to know whether he has an implant."
The sensors aren't strong enough for distance work but it's a good start, isn't it?
