Every Samsung smartphone contains a set of hidden codes that give you access to diagnostic tools, hardware tests, and settings not available through the standard interface. These codes are entered directly into your phone dialer — no app required.
Here is the complete list of Samsung secret codes for 2025, organized by function.
What Are Samsung Secret Codes? Samsung secret codes (also called USSD codes or service codes) are special sequences entered into the phone dialer that trigger hidden menus and diagnostic functions. They are used by technicians, developers, and power users to access information and settings that Samsung doesn’t expose in the regular settings menu.
Important: Some codes can modify system settings. Use them with care and only on your own device.
How to Use Samsung Secret Codes
- Open the Phone app on your Samsung device
- Go to the Dialer/Keypad tab
- Type the code exactly as shown (the action will trigger automatically — no need to press call on most codes)

- These codes work on most Samsung Galaxy models but availability varies by device model and Android version
- Do not share your IMEI number (*#06#) publicly — it can be used for fraudulent purposes
Frequently Asked Questions
Do these codes work on all Samsung phones?
Most codes work across Samsung Galaxy S, A, M, and Note series running Android 9 and above. Some codes may not function on carrier-locked devices or newer Android versions.
Are Samsung secret codes safe to use?
Informational codes (like #06# or #0*#) are completely safe. Avoid using reset codes unless you know exactly what you’re doing and have backed up your data.
Can I brick my phone with these codes?
Informational codes will not damage your device. The full factory reset code will wipe your data but won’t permanently damage hardware.
