For S8+ users, how is the GPS/maps accuracy? My wife has an S7 and I'm thinking of jumping from an iPhone 6 to an S8+, but the location accuracy of her S7 is garbage. Even if the location is identified correctly in Google Maps (about 50% of the time), the direction is incorrect, which makes turn-by-turn or pathfinding useless. She has downloaded that GPS coordinate app which is supposed to fix things, but it hasn't, and when it comes up with "this phone needs to be calibrated", nothing is improved after waving it around in the air.
I have heard that this is a particular problem on the S7. I hope the S8/S8+ has this all fixed?
