I tryed in enother area 180km away ,the problem is the same.

finally everything is corect i trye with a tablet instead of my smartphone and all are OK

I had exactly the same issue, the distance was ready 8 - 10 times more than actual distance from home. I tried 2 different android devices, then changed to my iPhone and everything was perfect.
