Unlike standard USSD codes (like *#06# for an IMEI) that work in the dialer app, Samsung has embedded a secondary hidden interpreter inside its Calculator app. By typing specific mathematical formulas or decimal sequences into the calculator and tapping the "Equals" (=) button, you trigger hidden activities, hardware tests, and engineering modes that are otherwise inaccessible to the average user.

These codes are primarily used by Samsung service center technicians to diagnose hardware failures, reset specific components, or calibrate sensors after a repair. For power users and developers, they provide a fascinating backstage pass to the phone’s internal health. samsung calculator secret codes

Important Note: These codes work on most Samsung Galaxy devices running One UI (typically Android 10 and above). However, due to carrier restrictions (especially on Verizon, AT&T, or locked devices), some codes may be disabled for security reasons.
