The Samsung Calculator secret codes are one of the last great hidden features in modern smartphones. In an era where manufacturers lock down bootloaders and hide system files, the ability to test your own proximity sensor, calibrate your compass, or check true battery health with a few taps of the calculator is remarkably empowering.
But with great power comes great responsibility. Use these codes to diagnose, not to destroy. Never change a setting you don’t understand. And always remember: the main service menu ((+30012012732+) is a window into your phone’s soul—feel free to look, but think twice before touching.
Now go ahead. Open your Samsung Calculator. Type (+123456+. Tap equals. And realize that your phone has been hiding its secrets in plain sight all along.

(also known as Factory Mode), which is primarily used for deep system diagnostics when a device lacks a phone dialer (like Wi-Fi-only tablets).

Some older Galaxy models (like the Galaxy S4–S7) had a hidden Easter egg in the Calculator app:
If you rotated the phone to landscape and swiped from the right edge, a scientific calculator appeared with extra functions. No code was needed.
First, let’s bust a myth. You cannot test your IMEI, check for wiretapping, or unlock a carrier lock simply by typing numbers into a basic calculator and pressing equals.
Instead, the trick relies on a specific unit converter hidden inside the Samsung Calculator app. You need to use the “Convert” function (usually found by tapping the ruler/calculator icon in the bottom corner).
Once you are in the Unit Converter view, the calculator becomes a gateway to Samsung’s secret Service Menu.
