When you go where you do not know, set your car as the destination and set it as the destination where you set the camping point that you parked. When you lose your road, if you can not locate your car, determine your destination and the compass will tell you how far you need to go and how far you should go.
Since the location information is received by the GPS in the open area, the position makes errors up to 160 meters compared to the GSM operator in the place where you are from GSM receivers in very low, domestic indoor areas.
In the case of Application pause, the backplane does not work because GPS consumes too much battery.
