Hey nprofile1qy2hwumn8ghj7un9d3shjtnyd968gmewwp6kyqpqha9ntrv3zurh8vmk7939a58dl087e0zz0vyfw3ghf390cpa06z7qzypw5t (nprofile…pw5t), make sure to have Wi-Fi scan throttling disabled in Android's developer options, and then in NeoStumbler set Wi-Fi scan frequency to as often as possible. :)
Something I've recently discovered is that even putting your phone in your pocket while walking in an open area can have a pretty big impact on GPS accuracy, so if you're trying to improve accuracy in a certain area it's a good idea to make sure your phone has a clear unobstructed view of the sky.
