Location tracking of phones is out of control. Here’s how to fight back.

This is a most excellent place for technology news and articles.
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.
NetGuard just outright blocks network access. Apps can't send tracking data if they are not able to access the servers. I'm using it in whitelist mode where I only allow access to apps that need it.
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.
