It is almost entirely handled by the SOC, there’s not much to see in SailfishOS, let alone Waydroid. Whenever a client requests highly accurate positioning information, geoclue-master starts geoclue-hybris which checks, if aGPS is wanted/allowed by the user (i.e. not in flight mode) and technically possible (mobile data connection available). If possible, geoclue-hybris injects current time and S…
