I'm having the exact same issues as OP. My GPS doesn't update correctly, I can move 4 blocks and have it do nothing, cross the street, and suddenly my guy flys half way across town- the other direction. I stand still and my guy randomly spins and walks in circles. I lost a Growlithe today because even when it appeared on the screen and I walked directly to the exact spot it showed, my guy wouldn't go anywhere near the area I was.
My town has two gyms, side by side- and two pokestops. All four locations are within the same one block of each other. AND THAT'S IT. Somehow, magically, at random intervals I don't have gps or data in that area. The same 4 blue guys that own both gyms don't appear to be having problems though. (884 cp Vaporeon? Really?)
Gps must be tied to the Incubator, because it's not registering any of the distance I walk. It won't let me activate Incense. Are those little puffs of stuff on the screen a thing? Because they never do anything in my game.
