Looking for Android secret codes and hacks? Here are the top USSD codes to improve the security and privacy of your smartphone.
Android is the world's most popular mobile app today, with over 2.5 billion devices. Also, if you have been using an Android device for some time, you may already know the USSD codes.
USSD codes, also known as "secret codes," are codes that are used to unlock hidden actions on your smartphone. Unstructured Supplementary Service Data (USSD) is a visual usage protocol that you can use to access hidden features on your smartphone.
To use any Android security code, you must enter it directly into the dial. If properly installed, the code will automatically return the answer, or you may need to press Dial. So what are the most common security codes for Android? And what exactly do "secret codes" do?
1. * 2767 * 3855 # (Wipe Your Device and Reinstall Firmware)
This is one of the most effective Android security codes you can use to quickly erase all information on your device. Think of it as the original reset — add this code to your dialog and launch it, and it will erase all data from your phone, and wipe it clean.
This code takes things a step further as it regenerates the firmware, so it will be as good as new, with the wisdom of the software.
Note: This is a difficult reset, and it will erase everything, so use only in a complete emergency.
2. * # * # 7780 # * # * (Use Original Reset)
If you do not want to start a hard reset, this is the next best option. Similar to the original reset, this code will automatically erase all app data on your device, as well as any apps. Then, it will restore your device to its original state.
If you do not want to go the extra mile to reset and install firmware, and just want to delete any personal data, apps, and app data from your device, this is the best option. That makes it better for your privacy when you sell your phone to it.
3. * # 06 # (Check Device IMEI)
This is another important code you can use to check if the device's IMEI is the same as the one in the box. Most modern smartphones have a printed IMEI in the background, but if you want to be sure, you can check it by using this code.
Just open the dial, add code, and it will reset the IMEI. If you do this on a Samsung Android device, it will also show you the serial number of the device. This is important for security purposes, especially if you are purchasing a pre-owned device.
4. * # 0 * # (Use General Test Mode)
Android phone not working properly? Understandably, you will have suspicions about the third party involved. Install this code on your Android device, and it will show you a collection of various features, including:
Touch testing.
Front camera.
LED.
Bottom key.
Barcode emulator test.
Device version.
RGB testing.
Touch sensor test.
If you suspect any root level interference in your device, you can check individual features using this mode. From the device version to the front camera, each module can be visually tested.
5. * # * # 232338 # * # * (Displays MAC Address)
Media Access Control Address, also known as MAC address, is the unique address assigned to every device. It is important as it can be used to identify a specific computer while connected to a network.
If you are in doubt about MAC spoofing on a device, you can view the MAC address on the device, and delay it on your network to make sure it is correct.
6. * # * # 4986 * 2650468 # * # * (Important Firmware Information)
This code is important as it returns important information associated with device firmware information. The code returns the PDA firmware information, phone, hardware, and RF call date, or production date. If you think someone has corrupted the firmware on your device, you can check the firmware details using this code.
7. * # * # 7594 # * # * (Change Power Button Behavior)
If you want to change the behavior of the power button, you can use this code. Instead of holding down the power button, then selecting Power Menu to turn off your phone, this code allows you to turn off your phone without showing any power menu at all.
This code can be useful if you want to quickly shut down your device in risky situations. The next time you open it, the device will need a passcode, thus keeping your data safe in case the device is stolen.
8. * # 3282 * 727336 * # (View System Information and Storage)
This key code allows you to view system information and storage. You can also view statistics related to data usage with this code. Although such data is difficult to deceive, that can be done. By using this USSD code, you can get accurate information about the internal Android system of the device, and the available storage.
Any data usage on the device will also be displayed on your screen when you use this code.
9. * # 67 # (Check Telephone Transfer)
If you want to know if your calls are being transferred to another number, use this code. This will tell you if the call transfer works on your device, and will show you the number to which your calls are being sent. In case the calls are forwarded when your number is busy or if you reject the call, you will know that too.
In most cases, you will only see this as your voicemail service for your carrier. You also have the option to change this setting by going to your Android call settings.
10. * 31 # (Disable Caller ID)
If you want to keep your privacy and prevent others from knowing when you call them, you can disable caller ID by using this code.
If you want to re-enable caller ID, just add code again. It will show you a message indicating that services have been enabled or disabled each time you add them.
11. * # * # 34971539 # * # * (View Camera Info)
The last code in our list allows you to view a wide range of information about the camera, including the number of cameras, maximum zoom, firmware version, and other details. Considering the fact that mobile cameras now include a number of modules, this code can help you identify any instances of interfering with the camera firmware.
