Although Android itself doesn’t have a built-in mechanism for analyzing these specific areas, you can find very effective infrared detectors that can be used for app tracking activity in unexpected places.
It is the DuckDuckGo Android web browser. DuckDuckGo is primarily known as a search service and Chrome replacement, but its Android app has a handy tool that lets you see exactly what kind of tracking activity is happening in the background in apps on your device and block some or all of that activity if you want.
You don’t have to set DuckDuckGo as your Android’s default search engine or default browser to take advantage of this option. In fact, with just about 30 seconds of simple setup, you can have all the information imaginable with simple controls at your fingertips.
Android app tracking insights in just 30 seconds
First, install DuckDuckGo from the Play Store, then open the app and go through a slightly annoying welcome process. If DuckDuckGo asks you to set it as your default system browser, you don’t have to. If you want to skip this offer and continue using the standard browser you’re already using, just hit “Cancel” on the pop-up.
Then, on the main DuckDuckGo home screen, tap the three-dot menu icon in the top-right corner of the app, select “Settings,” and then select “App Tracking Protection.”
Tap “Continue” a few times, then tap the blue “Enable App Tracking Protection” button and select “OK” when prompted.
