anyone else experiencing very unstable GPS signals on this device? Every other minute my GPS signal wanders off in a random direction for 20 or 30 seconds before it comes back to the place I am. Doesn't matter if I'm in the city or out in the open. I've found numerous sites discussing mediatek chips having GPS issues and the trend around 2013 seemed to be to fix the EPO.dat. Is that still the case? Any recommendations for modern Nokia devices how to fix bad GPS? It makes navigating in my car a challenge when I'm driving in a city and the GPS suddenly thinks I'm out in the sea.
