What Is This Code 27673855 Samsung?
The code 27673855# is one of the most important factory reset codes for Samsung phones. This code triggers a full factory reset without confirmation, so be cautious when using it. It erases all your data, including contacts, apps, and settings. Essentially, it restores your phone to its original state as it was when you first unboxed it.
This code is primarily used when your phone is having serious performance issues that can’t be resolved through regular troubleshooting. A full reset can help clear out software bugs, slowdowns, or any lingering issues caused by apps or settings. However, make sure to back up your important files and data before using this code.
It’s worth noting that this code should only be used in extreme cases when other troubleshooting steps fail. Factory resetting your phone can be a great way to fix problems, but it’s also a hassle because you’ll have to set up everything again from scratch.
What Does *#9090 Do?
The code *#9090# opens the Diagnostic Configuration menu on your Samsung phone. This is a hidden menu that allows you to view and adjust several testing and configuration options for your device. It’s mostly used by technicians and developers for advanced diagnostics.
When you enter *#9090#, you can access information like the diagnostic logs and system parameters. The menu allows you to test your device’s components, such as the camera, display, and sensors. It also provides information about network connectivity, battery status, and other internal components.
For the average user, this code might not be very useful unless you’re trying to troubleshoot a specific issue with your phone. However, if you’re a developer or someone familiar with Android system functions, the *#9090# code can provide valuable insights into your phone’s performance and health.
What Is the Use of #9900 in Samsung?
The code *#9900# is used to access the Samsung Diagnostic Tool, which is a collection of hidden settings and logs designed to help troubleshoot and improve performance. When you enter *#9900#, a menu appears with several options for testing your phone’s performance and resolving issues.
One of the most common uses of this code is to enable or disable certain features that may affect your phone’s performance. For example, you can turn off background processes or manage log files that might be causing your device to slow down. This is especially useful if your phone has been running slowly or if you’re experiencing unusual battery drain.
Using *#9900# can also help clear cache files that might have built up over time, potentially speeding up your phone. While this is a great tool for optimizing your device, it’s not recommended to make changes unless you know exactly what you’re doing.
What Does *#7353 Do?
The code *#7353# is another diagnostic tool for Samsung phones, specifically designed for hardware testing. When you enter *#7353#, your phone will run several tests on the key components, including the display, vibration motor, and camera. It’s a quick way to check if your phone’s physical components are working as expected.
Some of the tests you can perform using *#7353# include checking the LCD display, testing the vibration motor, and evaluating the camera’s performance. It also allows you to test the audio functions of your device, including the speaker and microphone. For example, when you tap on the audio test option, you’ll hear different sound frequencies to make sure your speaker is working properly.
This code is great for anyone who suspects hardware issues with their Samsung device. Whether it’s a screen issue, faulty vibration motor, or audio problems, *#7353# can help identify the problem quickly.
What Does *3370 Do?
The code *3370# is used to enable the Enhanced Full Rate Codec (EFR) on your Samsung phone. This codec improves the quality of voice calls, making them clearer and more reliable. Enabling EFR can help reduce background noise and improve the overall audio experience when talking to someone on the phone.
EFR is especially useful in areas where network conditions aren’t perfect, as it can improve call quality even when the signal is weak. However, enabling this feature may slightly increase battery usage, so you may want to disable it if you’re looking to conserve battery life. To disable EFR, you can use the code *3370# again.
If you’re someone who frequently makes calls and values high-quality audio, *3370# can be a game-changer. It’s a simple code that can significantly improve your call experience.
What Does ##4636## Do?
The code ##4636## is used to access the “Testing” menu on your Samsung phone. This menu provides detailed information about your phone’s performance, including its battery usage, network connectivity, and other system details. It’s especially useful for troubleshooting network issues or checking battery health.
When you enter ##4636##, you can view detailed information about your phone’s current state, such as its signal strength, network type (e.g., 4G, 5G), and other network parameters. Additionally, you can see your device’s battery statistics, including charge cycles, current charge, and battery health.
This code is helpful for diagnosing issues related to connectivity or battery performance. If you’re experiencing network drops or poor battery life, ##4636## is the place to start.

It’s a quick way to ensure that your device is running the latest software and to verify that all hardware components are functioning correctly.
When you enter #12580369#, the device will display information about the phone’s software version, including the build number, and the hardware version, such as the processor and memory. It also provides information about the PDA (personal digital assistant) and other key components of the phone.
For developers or users who want to ensure their phone’s software is up-to-date, this code is a useful tool. It helps you quickly verify that your device is running the latest firmware version.
What Does *31 Do to Your Phone?
The code *31# is used to hide your phone number when making outgoing calls. When you dial *31# before a phone number, your number will be masked, and the recipient won’t be able to see your caller ID. This can be useful if you want to make anonymous calls or if you don’t want your number to be displayed.
This feature can be especially helpful in situations where privacy is a concern. However, some carriers may restrict or block the use of this feature. If you need to disable it and display your number again, simply dial #31#.
Using *31# is a simple way to control the visibility of your phone number, allowing you to maintain privacy during calls.
What Happens When You Press ##002?
The code ##002# is used to cancel all call forwarding settings on your Samsung phone. If you’ve accidentally set up call forwarding or want to stop forwarding calls to another number, ##002# will disable it. This is especially useful if you’re experiencing issues with missed calls or calls being redirected unexpectedly.
When you enter ##002#, the phone will automatically remove any call forwarding settings. It resets the forwarding rules for voice calls, data, and even SMS. If you’re not sure whether call forwarding is enabled, using this code will ensure it’s disabled.
