What Are Samsung Secret Codes?

Samsung Secret Codes, or Samsung dialer codes, are alphanumeric characters explicitly created Samsung codes for android device debugging. Only Samsung devices should use these manufacturer-specific codes; applying them to other manufacturers could result in unfavorable consequences, such as irreversible damage.

• Manufacturer-defined MMI codes and USSD codes are the two main types of Android passwords.
• Man-Machine Interfaces, or MMI codes, give users access to hidden settings menus that smartphone manufacturers specify.

Mobile service providers employ a communication mechanism called USSD codes, or Unstructured Supplementary Service Data. These codes allow users to access carrier-specific features such as balance checks, data usage, and account information. On Samsung devices, some of these functions can also be accessed using a Samsung mobile check code, which helps users retrieve essential device and network information. Make sure you have a working network connection when using USSD or check codes.

How Secret Codes Interact With Samsung Software and Hardware

Samsung’s system software, which includes One UI and the previous TouchWiz interfaces, functions in concert with these secret codes. Upon dialing a code, the phone’s firmware is directly contacted to either display information or enter a specific mode, such as factory, engineering, or service mode. For example, typing *#0*# brings up the LCD test menu, while typing *#06# displays the device’s IMEI number, which is a hardware identification.

Safety and Precautions When Using Secret Codes

Secret codes must be used carefully even though they might be quite helpful. Entering specific codes may cause the phone’s hardware or software to alter, which could cause data loss or functioning problems. Understanding a code’s purpose before using it is crucial, and codes from unreliable sources should be avoided as they could produce unintended results.

Codes for System Information

• *#06#: To check IMEI (International Mobile Equipment Identity)
• *#1234#: For the serial number and software version
• *#0011#: To check the battery status and RSSI reading
• *#2663#: For firmware info such as AP, CP, and CSC versions
• *#12580*369#: To know about the manufacturing date of the device

Codes for Diagnostic Tests

• *#0*#: For a quick test of the device’s features
• *#0842#: To conduct a vibration test
• *#34971539#: For a camera firmware update
• *#0588#: To perform a proximity sensor test
• *#232331#: To check for Bluetooth
• *#0589#: For a light sensor test, including a screen test

Codes for Network and Connectivity

• *#7465625#: For GSM/UMTS info (Network Lock, Network, etc.)
• *#232338#: To check Wi-Fi and WLAN MAC address
• *#3282*727336*#: To see current data about networks with network statistics
• *#0808#: For USB Settings and connectivity options
• *#1575#: For setting up and testing the GPS

Miscellaneous Functionality Codes

• *#0808#: To access hidden USB settings
• *#2222#: For the device’s hardware version
• To display product code, press *#272IMEI# (Replace ‘IMEI’ with the actual IMEI number you obtained earlier.)
• *#272*IMEI#: To view the buyer code (Replace ‘IMEI’ with the device’s actual IMEI number.)
• *#*#7780#*#*: For a full factory reset

The list that follows offers a variety of Samsung-specific secret codes that enable more in-depth connection with the phone’s components and system. Because some operations may cause data loss or impair device performance, users should use these codes carefully.

Step-by-Step Guide to Entering Secret Codes

Using a Samsung secret code requires opening the dialer software on the phone, just like when making a call. Use the numeric keypad to enter the specific code. For instance, entering *#06# will provide the IMEI number of a phone. If the code is set up to reply automatically, the menu or information will show up as soon as the code is entered. If not, the code might need to be activated by pressing the call button.

Troubleshooting Common Issues

Entering a USSD code might not always produce the desired outcome. In these situations, the user should first make sure the code is correct and works with their Samsung device. Restarting the phone or looking for software upgrades can fix the issue if it continues. Seeking assistance from tech forums or official Samsung resources is also a smart idea. Caution is suggested because using out-of-date codes or entering codes incorrectly can result in mistakes.

Customizing Your Samsung Experience With Codes

Users can customize their Samsung phone experience by using secret codes. For example, inputting certain codes can access service mode for detailed diagnostic configurations, modify network connection settings, or bring up the firmware and software information page. However, because these codes might change crucial components of the phone’s functionality, they are only meant for experts or informed consumers. Before utilizing any code, users should be cautious and make sure they understand exactly what it accomplishes.
