NASA does conduct advanced "metal scans" and mineral mapping, but this is done through professional missions rather than consumer apps: Identifying Minerals Using ASTER - NASA Earthdata
This is one of the most reliable and straightforward magnetic scanning tools available for Android. It displays the magnetic field level (EMF) in (microtesla). Nature's standard baseline is around . If metal is near, the reading spikes.

✅ Your Android phone can detect metal using a built-in sensor called a magnetometer . This is the same sensor that powers your phone's digital compass by measuring the Earth's magnetic field. When you bring a ferrous metal (like iron or steel) near the sensor, it disturbs the magnetic field, and the magnetometer detects that change.
A powerful web tool allowing users to interactively browse global, full-resolution satellite imagery updated daily. NASA does conduct advanced "metal scans" and mineral
The app reads this sudden spike in electromagnetic levels (usually measured in microteslas, µT) and alerts you with a beep, vibration, or visual graph.
Finding electrical wires in walls or iron pipes in the ground. 2. Netigen Metal Detector If metal is near, the reading spikes
If you search the web for these exact terms, you will find dozens of websites offering direct APK downloads promising "Best NASA Satellite Metal Scanning." You should avoid these downloads for several reasons:
First, check if your Android phone even has a magnetometer. The best way to do this is to download a free app called Sensor Test from the Play Store. It will list all the sensors on your phone. If you see "Magnetometer," "Magnetic Field," or "Magnetic Sensor," you're good to go.
