I tried using my Galaxy S8 as my GPS the last time I was up in the GA/NC mountains, but it kept giving me a "lost GPS signal" so often it became unusable. I am not finding many options as far as improving location accuracy goes. It has WIFI and Bluetooth scanning, which I cant see making a difference out in the boonies, but does it?. Anyone else have/had issues with the S8? Know of any fixes?
