Do I need to change the phone settings after an update of my iPhone (iOS) ?

It is not necessary to change the phone settings after an iOS update. In some update cases, you may need to adjust the location services of your phone. To do this, go to Settings > DriveQuant (in the application list) > Location Services. Then click on "Always".

You will also need to allow the application to access your "exact location".

Moreover, many users have reported GPS-related problems after updating their iPhone. Therefore, it is recommended to restart your iPhone once more after an iOS update because sometimes the GPS sensor is incorrectly reset.
