I never use the app, my phone geotags my images including accuracy, I use the browser to add all my observations. If your camera-phone bluetooth connection is using android, you need to make sure you have the ‘record accuracy’ or ‘high accuracy’ settings turned on, for it to record accuracy, otherwise it just adds the lat/long. Cant help with the onboard GPS chipset, but I would look for similar settings you may need to turn on to record accuracy. If you cant find a way you will just have to set it manually for every upload, or you could use a bulk exif editor to add accuracy to all your images for a value you are comfortable with.
