First, ensure you are using the latest version of our app. Many devices have special GPS behaviors, and the latest version of the app handles these behaviors the best. To upgrade the app:
Enter the "Play Store" app from your app drawer.
Tap the menu button and click on "Settings". Tap on the "Auto-update apps" and select the second or third option, pick which ever one better suits your situation.
Return to the "Play Store" menu then tap the menu button and select "My apps". From this list, scroll down to find our app and select it.
Then from the details view, you may select the "Update" button if you see one (If you only see "Open" and "Uninstall" then you already have the latest version). If you have already paid for the + version, you will not be charged again.
