GPS tracking and shapes recording
When recording the track or shapes, with the internal device GPS unit it is important that user extend Location Permission of the app to allow location at all time. This is because the app needs to record the location even when the app is in the background. So for example, if you wish to record the shape of the field by walking around it and keep the device in your pocket, the app needs to be able to record the location even when the app is in the background. If the permission is not set to allow location at all time, the app will not be able to record the location when the app is in the background and the shape will not be recorded correctly e.g., the shape will be recorded as a straight line from where the screen was locked to where the screen was unlocked.
