My location is not accurate, how can it be corrected?

For this, you need to make sure that the phone has all location services turned ON along with the data services or WiFi.  If the phone was manually turned off or got shut down due to running out of battery, the app should be opened as soon as the phone is restarted to set up a good connection again.

Also, when the app is opened on the phone, it will improve the accuracy of the location but when the app is running in the background, location accuracy will not be as high. Location accuracy also depends on the surroundings of your phone. Sometimes due to very poor signal, a highly accurate location is not detected. So, you need to check the strength of your data signal.
