The GPS on your phone is never off, and if the signal is weak the GPS signal will boost itself at the expense of your battery. Remember back in the day when Samsung phones were catching on fire? Schools have lousy reception, a dropped phone with a lightly damaged battery that's expending shitloads of current to boost GPS signal gets warm for no reason? Riiiiight.
I don't think you can "boost GPS signal" at the device end since it's the receiver
Well you get the idea, I'm pretty stupid when it comes to electronics, so it's natural I'd confuse the jargon absentmindedly. Correcting grammar or words nets no new knowledge or understanding let alone agreement, would be nice if you could add to the discussion. Give some insight or understanding other than nitpicking minutiae.
The identification process works through your phone's communication with the cell it is in. GPS isn't really needed to locate your phone at least in terms of which cell it is currently in. AFAIK the phone will ping the cell tower even when it is off, so there is the danger. The GPS module shouldn't be able to send, just receive the satellite signal. On the other hand, there is the locate-my-phone function, which should involve some kind of triangulation,
Samsung uses other Samsung phones to track your phone's bluetooth connection, which is quite unnerving. It's also how the contact-tracing for the Convid works: (cnet.com)
However, more recently, Samsung announced a new service called SmartThings Find. The new feature works like Apple's Find My app by crowdsourcing the location of a lost device, even if it's offline, but telling nearby Galaxy devices to look for its Bluetooth signal and report its location if it's found. All of which, of course, is done anonymously.
