thanks Mike for your reply. I tried the GPS4ppc tool
http://www.b4x.com/forum/open-source-projects/5208-gps4ppc-v2-0-a.html
from Erel / Ariel and same result (variable position).
Surely the internal GPS of my chinese phone isn't very good...
The average seems to be a good way to solve it, works fine?
I am thinking in another possible solution, rounding the lat/lon to 4 decimals, and it would have a precission about +-4 mt (I guess it would)
