Rallycheck uses GPS positioning to determine the location of your phone. Without the GPS function Rallycheck will not work correctly. It is very important that your GPS positioning is active!
1. Are you outdoors?
In some buildings and most tunnels GPS positioning does not work because the signal is unavailable. Make sure you are outdoors when testing your GPS signal.
2. Is your smartphones location services activated?
Your smartphone enables you to switch the Location Services (GPS) on and off. This is a setting for the entire phone, so even if you have given Rallycheck permission to use Location Services, this may not work because the service has been disabled for the entire phone. Make sure Location Services is activated.
3. is the Rallycheck app authorized to use Location Services?
When installing Rallycheck you will be asked to allow Rallycheck to make use of the Location services of the smartphone. Make sure you have agreed to this! If you are unsure about this setting, you can check this on your phone. Go to the “Settings” of your phone and select the appropriate Location Services menu. There you will see a list of app’s that may use Location Services. make sure Rallycheck is in this list and that use of Location services is enabled.
4. Do not use magnetic phone cases!
Some people make use of magnetic phone cases. This is very bad for all types of antenna reception. The following phone functions use an antenna:
- Calling someone
- using internet
- using WIFI
- Using Bluetooth
- GPS Location Services
Al these functions are partially impeded when using a magnetic phone case! Do not use a magnetic case. We have done some measurements for Rallycheck and were able to determine that the accuracy of some phones were reduced frome 3 meters to 20 meters when using a magnetic phone case.
5. Turn off other aps that use Location services.
We have seen that some people have up to 30! apps, all of them using Location Services, active at the same time! That is a huge number of apps. Be aware that many of these apps will keep track of your location continuously. Some of these apps register your location every second, 24 hours a day! This information are collected and used by a number of third parties. If you are OK with this, no problem.
Your phone, however, has only 1 GPS chip. All these applications want to make use of this single GPS function, this can lead to performance problems for the Location services. We advise all users of Rallycheck to “Swipe” all the other Location apps from memory. Check your phone manual for specific instructions on how to do this for your phone.
