Android spies on you!
In 2015, Fox News' Tucker Carlson Tonight aired an investigation into just how much information Android collects about you - and sends to Google. You can watch the full segment on YouTube. Spoiler: Android tracks everything you do and everywhere you go with terrifying precision, and yes, your government - wherever you are on this planet - has access to that data on demand.
Android is Google's flagship smartphone and tablet OS. It's been around for a long time now, and is no longer the open platform it once was. Android today engages in broad spying and surveilling of you as a user, even if you think you've disabled every privacy-related setting in the OS.
While some forks of Android, such as LineageOS, attempt to strip the Google elements from Android, ultimately you are still beholden to Google if you want to install most modern apps.
