On my S4 I find using GPS Status (free Google
Play App) first always helps. I have to go to Settings > Location and turn it on. All Samsung tablets and phones have a built in GPS. I was looking into this because I thought they had taken it out ofg newer tablets, and called about 4 months ago and was reassured by the tech that they have not. It did not sound like the had any plans to change having a GPS as they regard it as important. (my reading of the discussion).
GPS Status just gets it all working faster finding satellites etc. If you've used GPS it recently you do not need it really. Also you can download a Sensor App like Sensor Readout to determine which senosr, ...there are gyroscope sensors, acclerometers, gravity sensor, linear accelerations sensor, magnetic sensor, 3-axis sensor. RH and barometer sensors, but I don't see the GPS indicated here on my S4... so that won't help.
