could you do me a favor? about nav4all.
I recently downloaded a new navigation system into my mobile phone. But Sometimes the system does not work so well. I am wondering if environmental factors preventing the GPS from calculating a correct position. How to deal the problem?

Just kidding. I'm not expert, obviously.
