own a cell phone metal detector is possible today, thanks to the technology of the digital market.
Gold and metal detectors have a very long and interesting history.
The first metal detector was created in the mid-1800s, from the invention of electricity, where scholars had the idea of developing a machine that could detect metals buried in the ground.
The first attempt at creating a metal detector was when US President James Garfield was shot at the Baltimore train station.
A detector was then created to try to save him, but the attempt did not work, as the springs of the bed where the president was, confused the machine and he could not resist his injuries.
These machines were incredibly large, complicated to handle, and operated with vacuum tubes, but as they were proving useful, they continued to be used until Fisher was able to create a portable detector.
Later, Charles Garrett, an electrical engineer, started to detect metals as a hobby and because of that, he created a more modern machine, capable of detecting metals without oscillation.
The search for technology led to other detectors being created and today we have an infinity of detector models for different functions, portable and easy to use, including detectors for cell phones.
Metal detectors are extremely useful, especially for finding metals hidden underground, including gold.

O metal detector is a specific application for Android phones to detect metals.
A very simple tool to use, just direct the cell phone to a specific metallic leftover for it to recognize it, it works as a kind of magnet, from a digital compass on the cell phone, capable of detecting magnetic fields.
After its proper installation, the application automatically searches for metallic objects in the vicinity and scans the object, showing it through the word :detected: on the cell phone screen.
When downloading your application, the user can choose whether he wants the device to vibrate only when it encounters a metallic object, or to emit a certain sound, in addition to being able to change the detection sensitivity, making the application able to find more metals quickly.
However, we have to say that the more sensitivity the tool has, the more battery your mobile device will use.
If the application does not work properly, it could mean that the sensors on your device are damaged, have very high temperatures or are simply non-existent.
Another curiosity of metal detectors for cell phones is that they are directly affected by any electronic device such as TV sets, computers and others, due to their electromagnetic waves, so they should not be used near them.
The metal detectors found on the market today are used for various types of segments, such as banks, armed forces, exchange offices and concert presentations, to ensure security.
In most cases they are used specifically to detect weapons or other dangerous objects and ensure the safety of people on the scene.
In the case of the Metal Detector application, it is clear that everything is a joke, as it is not so stable when it comes to finding metals, the tool developers themselves make it clear that the application can be unstable in some cases and not detect the objects of the correct form.
The application works, of course, and according to some users it can identify various types of metals, but it does not replace professional devices used in banks and other institutions.
The app is free and its language is English.
