How it can be: no last known valid pos. - but with my coords. and 4-5 green sats on the " gps monitor"

Green sats means used in taking fix with GPS receiver.
But GPS receiver in addition to coords gives flag denoting is fix valid it or not.
(the state of this flag shown with color of status line on the bottom of screen
red = invalid, black = valid)
GPS can give coords pointing to your location but mark it as invalid due to
small number of sattelits or due to low signal/noise ration from satellites it used in fix.
While it is marked as invalid then application do not lock to it.
After GPS fix becomes valid you can press "center to gps" buttone
(one with 4 arrows) to center screen on you location
