Hi !
Sorry, I'm not sure to understand what you mean.
This aGPS function (Xtra download) only download ephemeral, like tell Vlad.
So it is a pure GPS function and it don't use WiFi or Bluetooth or scanning near cell tower.
For the test please disable all GPS improvement system : So in Android settings : Improve Location Accuracy = off and Wi-Fi scanning and Bluetooth scanning = off and not in High Accuracy mode.
So you need to put you Android in Device only GPS to be sure to disable all other functions.
It just download a satellite map at this moment. And we just need Internet data (mobile data or Wi-Fi) just one time a day. You can download the data in your home and use GPS after.
We use SatStat to download aGPS (the first option in the menu).
So you can do the experiment as you share at the top of the topic, or like this :
I prefer this way, because we are sure that it don't use other function that ask an external server to give the location.
Open Waydroid
Disable GPS in Waydroid
Start SatStat
Download aGPS in SatStat (the first item (Recharger les données AGPS in French) like in the Vlad picture)
Wait 30 seconds and after Turn off Wi-Fi and Mobile data
Close SatStat
Go outside
Enable GPS in Android
Start SatStat and look, verify that it found GPS (at the bottom) and look at the TTFF : Time To First Fix. It should be quicker than 1 minute.
Is it possible for you to test it ?
Thanks a lot
