What Are Samsung Device Test Codes and How Do They Work?
Samsung device test codes are unique sequences that can be dialed directly from the phone’s dialer. These codes grant you access to hidden menus that provide diagnostic tools, settings, and device information. You can use them to check things like battery health, test hardware components, or even initiate a factory reset to restore your device to its original state.
These codes are often used by developers, technicians, or advanced users who want to get more granular control over their device. Some test codes may also be used to troubleshoot common problems that users face, such as poor connectivity, slow performance, or malfunctioning sensors. By using the right codes, you can run diagnostics or clear up software issues with ease.
The most common use for these codes is performing a factory reset. A factory reset wipes all the data on your device and restores it to its original factory settings. However, the codes offer much more, allowing you to run system checks, debug issues, and manage network settings. Let’s take a closer look at some of the most important codes available for Samsung devices.
How Can I Perform a Factory Reset Using Test Codes?
A factory reset is often the best solution when your phone is acting up or you want to clear all your data before selling or giving it away. Samsung devices allow you to perform a factory reset through the settings menu, but there are also test codes that can get the job done faster.
One of the simplest test codes to perform a factory reset is *2767*3855#. This code wipes your phone clean and restores it to its original factory state. It’s an effective solution when your phone is not responding properly or if you need to remove all personal data quickly. Keep in mind that once the reset is completed, all data on the device will be lost, so it’s important to back up any important files beforehand.
Another useful test code for a factory reset is ##7780##. This code will perform a soft reset that removes personal data but keeps the device’s firmware intact. It’s a less drastic option than the first code but still clears most of your personal information, including apps and settings.
Both of these codes are accessible from the dialer and don’t require any special knowledge of the device’s operating system. Simply dial the code and follow the on-screen instructions to perform the reset.
What Are the Most Common Debugging Codes for Samsung Devices?
When things go wrong with your phone, debugging is the next step after a factory reset. Samsung devices come with several hidden codes to help you debug the system, check for errors, and perform various tests. Debugging tools help pinpoint issues with hardware or software that may not be immediately obvious.
One essential debugging code is *#0*#. This code opens a diagnostic menu where you can test several components of your phone, such as the display, camera, sensors, and touch functionality. The device test menu includes options to check the screen, vibration, camera, and speaker. It’s a quick and easy way to check if something on your device isn’t functioning properly.
Another code for debugging is *#1234#, which shows the firmware version on your Samsung phone. This code can be helpful if you need to verify that your phone is running the latest software version or troubleshoot software issues. For users who need to dig deeper into their phone’s software configuration, this code is invaluable.
In addition, *#0228# is a helpful code for checking the battery status. It displays the battery voltage, temperature, and other health indicators. Debugging battery issues is crucial for those who experience rapid battery drain or charging problems.
How Can I Test Hardware Components Using Samsung Test Codes?
Sometimes, the issue with your Samsung phone may lie in its hardware components, such as the touchscreen, camera, microphone, or battery. Fortunately, Samsung offers several test codes that let you run hardware diagnostics to check if everything is functioning correctly.
To test your phone’s display, use the code *#0*#, which will take you to a test menu with options for checking the color display, touch sensitivity, and pixel mapping. This can be useful if you’re noticing screen issues like dead pixels, discoloration, or unresponsiveness to touch.
Another useful code for testing hardware is *#7262626#, which opens the GPS test. If you’re having trouble with your phone’s GPS location accuracy, this code allows you to perform a diagnostic test on the GPS module and ensure that it’s working properly.
For camera testing, you can dial *#34971539# to bring up the camera’s firmware version and check if the software and hardware are properly synced. If you’re facing issues with taking photos or videos, running this test can help identify whether the problem is related to the hardware itself.
What Is the Code to Check the Battery Health on Samsung Devices?
Your phone’s battery health can significantly impact its performance. If your Samsung device is draining power too quickly or not charging properly, you may need to check the battery’s health to see if it’s time for a replacement. Fortunately, there are test codes specifically designed for this purpose.
To check the battery information on a Samsung phone, dial *#0228#. This code provides detailed information about your battery, including its voltage, temperature, and overall health. If your phone’s battery is performing poorly, the code will show signs of stress, such as a high temperature or low voltage.
Another helpful code for checking battery statistics is *#*#4636#*#*. This code opens the Testing menu, where you can view information about your phone’s battery status, including its capacity, temperature, and charge cycle. By keeping track of this data, you can determine if your phone’s battery is still healthy or if it needs to be replaced soon.
Monitoring your battery’s health regularly using these codes ensures you stay on top of any issues and can avoid unexpected battery failures.

How Do I Test Network and Connectivity Issues on Samsung Devices?
Network and connectivity issues are some of the most common problems users face with smartphones. Whether you’re having trouble with Wi-Fi, mobile data, or Bluetooth, Samsung’s hidden test codes can help you run diagnostics and find out what’s wrong.
One useful test code for Wi-Fi testing is ##232338##. This code displays the Wi-Fi MAC address of your device, which can help with troubleshooting network issues. If your Wi-Fi is not connecting or experiencing slow speeds, checking the MAC address can help you determine if the issue is with your device or the network itself.
For Bluetooth connectivity, you can use the code *#0588#, which opens the Bluetooth test menu. This allows you to check if your Bluetooth module is working correctly and test its connection with other devices.
Finally, if you’re experiencing mobile data issues, use the code *#*#4636#*#*. This code provides you with access to the Testing menu, where you can view information about your phone’s network status, including signal strength and connection type (e.g., LTE, 4G, 3G). Running these tests can help you figure out if there’s an issue with your network or if the problem lies with your phone.
