I keep all my location and GPS services turned off, by default, on my Android phone - however I was totally unaware that the phone had the capability to tag my photos as well.
After reading the article, I checked the settings menu on my phone's camera and discovered the GPS setting was in the "OFF" position.
Having never previously tinkered with that setting, I can only assume one of two possibilities is true in this case -
Either the GPS setting on my phone is set in the "OFF" position by default -- or (more likely) it's connected to the main location settings on my phone, which I keep turned off unless I have a specific need for them at any given moment.
One thing I have noticed is that my phone will tag each picture with the date it was put on the device - either directly with the camera, or uploaded from another source.
TMI - If you ask me.
