GPS, or the Global Positioning System, is a global navigation satellite system that provides location, velocity and time synchronization.
If you experience any of the following, your activity may report a different distance than you actually traveled, and, unfortunately, it will not be possible for us to “fill in” the missing data or modify the existing data. Thankfully, there is more that can be done to prevent bad GPS data from being recorded than there is to repair it. Please refer to the troubleshooting steps listed in this article to prevent similar issues in the future.
To achieve fast startup and high-accuracy position estimates, you should provide:
Turn the phone off/on.
Turn GPS off/on.
Be sure QPaws is allowed to use your location. Settings > Apps > QPaws > Permissions > Toggle Location ON. Be sure that you’ve allowed QPaws to use GPS in the background.
Disable any battery saver settings including Power Saving Mode, Battery Management, Optimization, or any third-party apps. More information on specific devices running Android 6 or higher:
Settings > Power > Battery optimization > Not optimized > All apps > QPaws > Don’t optimize > Done.
Turn Energy Settings to Normal and add QPaws to “Protected Apps.”
Settings > Apps > Advanced > Ignore optimizations > Allowed > All apps > QPaws > Allow.
LG: Settings > Battery & power saving > Battery usage > Ignore optimizations > turn ON for QPaws.
Motorola: Settings > Battery > select the menu in the upper right-hand corner > Battery optimization > Not optimized > All Apps > QPaws > Don’t Optimize.
OnePlus (using OxygenOS Settings): Settings > Battery > Battery optimization > select menu at the top > switch to All apps list > QPaws > Don’t optimize.
Samsung: Settings > Apps > select the menu in the upper right-hand corner > Special access > Optimize battery usage > All apps > Toggle OFF for QPaws.
Sony: Settings > Battery > select the menu in the upper right-hand corner > Battery optimization > Apps > QPaws.
Xiaomi (MIUI OS):
Check that your location settings are set to High accuracy. Settings > Connections > Location > Locating method > High accuracy.
Perform an “AGPS reset” by installing the App GPS Status & Toolbox, then in that app, go to Menu > Manage A-GPS State > Reset.
Try using the QPaws app to record for 10 minutes, letting it search for signals with a wide-open view of the sky, and keeping it completely immobile. If this does not produce useful location estimates, determine if GPS works in other apps. It’s best to use another fitness tracker app and not a navigation app like Google Maps, Waze, or Apple Maps. Navigation apps use cell towers to snap your position to known roads and trails which can give the illusion that your GPS is working perfectly. QPaws and many other fitness apps do not do this and just use GPS to position you. Because of this, you may notice QPaws is having a hard time locating you but other navigation apps aren’t.
Try running one of the free apps that present detailed GPS operating information. “GPS Status” is a free app that can reset your GPS and download fresh A-GPS data. The link to download the app is here, and you should see it eventually reporting 5 or more satellites acquired, and an overall accuracy range of fewer than 30 meters if everything is working properly.
Even if your device is in the same place and the same setting as before, it may behave differently from one day to the next. Typically, the device needs to receive signals from about 5 satellites to get an accurate estimate of its position. With the changing position of the satellites, changing weather patterns, and the changing nature of the Earth’s outer atmosphere, there are enough parts of the GPS system outside of your direct control and observation that it is difficult to make conclusions about what specifically is causing inconsistent performance. We recommend you try repeatedly before making a judgment about the best ways to work with your device’s GPS in your settings.
