android location cache
Data 'secretly' recorded by my Android phone OS, plotting the location of cell masts and wifi access points I've hit, a nice clear example. I did an industrial placement visit in west London, and this screen shot shows the series of points where my tablet connected as the train traveled north. For example you can see I traveled on a Southern Railways route via Crawley rather than the more expensive SouthWest trains route via Guildford. Date and time is recorded. Potentially useful as digital evidence I suppose, and useful for a digital forensic investigator to know about. The location cache typically records the last 50 cell masts and the last 200 wifi points. Rooted apks can be used to display the data, or clear it, and you can turn it off in Android Settings if it worries you.
