Some Android phones have power saving features that with default settings may terminate apps running on background. You can fix the problem by changing power saving settings. These settings vary between phone models and OS versions but it should go somewhat like this. Go to Phone Settings -> Battery -> Launch and change the app from "Manage automatically" to "Manage manually". Ensure that "Run in background" is enabled.
Also check the powermanagement in app settings
To improve tracking accuracy, please check these things first:
* Make sure APP optimizing is disabled from the phone's battery settings.
* Add the APP to unmonitored apps list in the phone's battery settings.
* Make sure you have the latest app version installed from Google Play
* Stop all unnecessary apps running on the background. (The recent applications menu- Close all possible)
* You have approved Location Services for the app in your phone’s privacy settings
* Change location mode to High Accuracy in the phone's GPS settings.
* Enable Location services in phone settings. It may take up to 10 minutes to acquire a GPS signal.
* Enable A-GPS (Assisted GPS) in the phone settings in 'Location method'
If you are still having tracking accuracy issues, you can try the solutions below:
* Go to Google Maps settings and find location source, switch it to device only. Go somewhere where there is clear sky view to gain optimal GPS connection with Google Maps.
Then go to The APP and start a new workout.
* Test that your GPS chip is working. You can use a (free) GPS test APP from Google Play for this.
* Reinstall the APP. Check first that workouts on your phone has synchronized.
* Reboot your device
The accuracy of your workout results depends on many factors such as the quality of the GPS receiver on your phone (it varies depending on the phone model), signal strength in your area (mountains or tall buildings can cause interference), weather conditions, and how you hold your phone while exercising.
The app uses only GPS for tracking. Other apps (for example, Google Maps) can use the "fused" location provider, which uses GPS, cell tower, Wi-Fi, and more to provide location info.
When starting a new workout, the map (location dot and GPS indicator) should look like this:
