The Saphe Link app calculates speed based on the phone's GPS, and this places some demands on the accuracy of the data provided by the phone's GPS. If they become sufficiently inaccurate, they will be completely excluded from the calculation. If the accuracy of the GPS is not sufficient, you may find that:  


  • The speed jumps up and down 
  • Is more than 3-5 km higher or lower than the car's speedometer 
  • The speed is not updated continuously 
  • The speed is shown as dashes "--"  


This can mean that you do not get alarms, or that you get false alarms, so it is especially important to be aware of.  


There can be many reasons why data from the GPS is inaccurate or missing, so here are some of the most common causes and solutions to GPS problems on phones.
