- Unless you don't want Google to know your location constantly, no matter what setting you use for the GPS chip.
- Unless you want security updates past a year.
That's not been the status quo any more for a while since the EU started to mandate several years of OS and security updates. Samsung and I believe Google as well have stated they'll do 7 years of udates.
> 1 Availability and timing of Android OS upgrades and security updates may vary by market, network provider and/or model.
note that it says "up to 7 years" and may vary by market. and has only been in effect for 15 months so there isnt a track record to say it will actually happen.
Ironically Googles Pixel phones have the longest support of any phone OS with guaranteed at least 7 years of security updates.
On my phone it is off and stays off. Unlike on iOS when it turns itself on.
Their map of wifi SSIDs allows pretty accurate geo-location, with no GPS.
This doesn't apply to you if you travel in an area with no wifi hotspots. The hotspots don't need to be publicly acessible, only the SSID needs to be visible for the hotspot to serve as a geo-location waypoint.
