I will test, but it doesn’t give me so much hope. It doesn’t seems to be linked with gps signal, as it should also find a position with ground antenna only. And it should display a fake position when fakeGPS app is enabled. So, it is more like if the location functionality was never enabled or something like that.
UPDTATE : I tried to reboot the phone and to activate the GNSS outside, and after some seconds, it worked. I tried to disable wifi and to activate fakeGPS and it stopped to work. I rebooted and activate only GNSS, without wifi and it worked. I launched fakeGPS, and it stopped.
I rebooted indoor and reactivated wifi positioning and it found a position at 150Km from me.
So it seems the positioning by satellites work. At least until I try to cheat it.
