I was told by Sprint that this is a known problem and they have no actual solution for it....I guess I'll wait for the new Note to come out (I am due a new phone anyway)
*#9090# (*#197328640# if that doesn't work) -neither of these codes worked for me...I am using a Note 3 for Sprint (USA)...my GPS is completely useless at this time...any ideas/suggestions (I have already tried the apps -not the ones that need rooting- and still no joy)
