This is a most excellent place for technology news and articles.
If you have a device that's actively connected to a cellular network, and has been while in your home or work, then your only option is to leave it behind or turn it off. That includes your car if it was made in the past decade, if nothing else, so it can catch OTA firmware updates, and send telemetry data.
GPS and location services don't mean shit when your carrier keeps logs of where you've been based on cell-tower triangulation.
One thing I am always aware of are apps that want permission to access Bluetooth and/or Wi-Fi and/or Networks.
Even though Bluetooth is very short ranged it can still be used to tie you into a location within a database based on other database records that are more detailed.
Yeah, I love playing you “My Great Dog-sitting Simulator” (not a real app) but you do not need access to my BT. The OS handles sending your audio to my headphones!
I remember when Bluetooth started demanding location permissions. You'll never convince me that it's functionally required or provides any benefit other than furthering efforts to spy on the user.
When it started being rolled out, I avoided any app or hardware that made that demand. Sadly, that's no longer an option if I want any Bluetooth at all.
It's not like Bluetooth started demanding location permissions, the conceptual model of the permission was revised: having access Bluetooth means an app could determine your location via a form of lateration.
In earlier versions of smartphone operating systems, this was not transparent to users lacking the technical background, so Bluetooth also requiring location access is actually an attempt at making users aware of that. I'm not an iOS developer, so I can't comment on iPhones, but on Android versions prior to 11, having access to Bluetooth meant an app would be able to determine your location.
Today, you can require the permission ACCESS_FINE_LOCATION, which expresses that your app might use Bluetooth to obtain location information on Android. Also, if you're just scanning for nearby devices to connect your app to, but don't want users to be confused why your smart fridge app needs to know your precise location, you can declare a permission flag (neverForLocation) and Android will strip beacon information from the scan results, better asserting your intentions.
So, overall: no, there is nothing nefarious going on, it was always possible to determine your location via Bluetooth, and the update to the permission model was an honest improvement that actually benefits you as user.
Now, there are still plenty of shady apps around, and apps that are poorly written - don't use those.
I knew that someone would try to convince me. You won't convince me.
... Though your argument is pretty compelling.
Teams is the worst, you can’t join any call if you don’t allow it to scan your local network. I wish the executives a very nice and agonizing death.
I haven't done an extensive survey or anything, but every modern router I've interacted with supports setting up a secondary WiFi network with guest isolation (so anything on that SSID can't see any network device besides the router and itself). This is useful for apps or hardware that is untrusted and/or demands unjustified permissions.
Pretty easy steps; get app you are interested in. Deny it access to things it doesn’t need when asked. If the app proceeds to not work until you enable, delete. Otherwise, enjoy app without the unnecessary permissions.
That's my approach with Rethink DNS. I get FOSS alternatives whenever acceptable for my use case, but isolate even them to only bare working minimum of outside connections.
Most apps literally don't work right is you do not enable all location services
11 out of 32 apps requesting location on my phone have the permission granted, because I actually need them to use location for one reason or another. the rest works perfectly fine with the permission disabled.
Don't just give location access to any app that requests it, especially background location access.
Even my taxi apps receive/lose location access automatically on open/close.
