Map will display latest known location, but you can always check the time.
In the next release there will be device connection status indication. For Traccar Client device it would turn from green to yellow if device hasn't sent updates for some time.
When tracker is off, it will show last location. If you click location of tracker, it will also show time stamp when last location was sent to server.
This is last time stamp that last know location was sent : http://s8.postimg.org/worss7vwl/Capture.png
if the android client is used and the user switches tracking off will the map display the last know location or somehow let us know he is in do not track mode?
my worry is we think he is at last known location and will cause inaccurate locations.
Will the server know his tracking is off?
