Is there a way to actually figure out which satellites the watch is using for positing? On my S8+ I can run a GPS test application which will report the status of the lock on all the satellites the phone can see. On my really old garmin hand held GPS you would also get GPS satellite info, but it seems there is no way to know which satellites the watch is using for lock.
In short I'd like to do some testing, but I see no way to tell if the GPS+Galileo setting is actually seeing the Galileo birds.
