Android is the most popular mobile operating system in the world today. In addition to being the most common mobile operating system, Android is also home to the most commonly used back door codes.

It is well known that Android devices have several back door codes that can be used to access hidden functions. USSD codes, which are alternative names for “secret codes”, are codes that you can enter into your phone to access hidden functions. The following is a list of the most frequently used Android security codes and their functions.

1. View the Phone’s IMEI

USSD code: *#06#

To see your Android phone’s IMEI number, you can use this secret code. As its digital fingerprint, your smartphone’s IMEI (International Mobile Equipment Identity) is an essential unique identifier.

The IMEI is a code printed on most modern smartphones, usually on the back. You can check the IMEI by using this code: Simply open the dialer and enter the code. The IMEI is important for security purposes, especially if you are buying a second hand device.

2. Wipe Your Device and Reinstall Firmware

USSD code: *2767*3855#

If you need to quickly wipe all data from your Android device, you can use this code. It’s similar to a factory reset, and it will delete all data from your phone and reinstall the firmware. This will make your phone like new again, software-wise.

3. Check Call Forwarding

USSD code: *#67# 

To check if your calls are being forwarded to another number, use this code. This will tell you if call forwarding is active on your device, and will also show you the number your calls are being forwarded to. In the event that calls are being forwarded when your number is busy or when you reject a call, you will be notified. In most cases, you will only see this as your carrier’s official voicemail service. However, you have the option to change this setting by accessing your Android’s call settings.

4. Enable Call Waiting

USSD code: *43# 

If you frequently receive calls, call waiting may be a beneficial feature for you. With call waiting, you can answer a second incoming call by putting your first call on hold. Additionally, you may be able to switch between calls. For example, if you believe you are speaking with a scammer and someone else calls, you have the ability to switch to the other call and take time to think through the situation and potentially seek advice. To disable the call waiting service, type #43#.

5. Run a Factory Reset

USSD code:

This code will delete all application data from your device, as well as any applications. Then, it will return your device back to its factory state. This is a good option if you don’t want to hard reset your device or reinstall the firmware, and you just want to remove any personal data, applications, and app data from your device.

6.  Check SAR Level

USSD code: *#07#

This code lets you view the Specific Absorption Rate (SAR) level of your Android phone. The SAR level is a measure of the electromagnetic energy your body absorbs while using the phone.

The Federal Communications Commission (FCC) requires that all smartphones have a SAR level no higher than 1.6 watts per kilogram. If your phone exceeds this limit, it may be time to consider upgrading to a new model.

7. Perform GPS System Test

USSD code: *#*#1472365#*#*

To check the strength or efficiency of your Android GPS, use this USSD code.

Knowing whether your smartphone’s GPS is on or off can save you in various situations, like losing your phone or getting your device stolen. If it’s active, you can use its GPS to locate your phone.

8. Do a Touchscreen Test

USSD code: *#*#2664#*#*

This security code is just like the GPS test code in that it lets you check whether the touchscreen of your device is working. When you are purchasing a used phone, it will come in handy to have this code.

9. Activate General Test Mode

If your Android phone isn’t working properly, you might suspect that a third party is affecting it. Enter this code on your Android device, and you’ll see a list of different features, including:

  • Touch testing.
  • Front cam.
  • LED.
  • Sub key.
  • Barcode emulator test.
  • Device version.
  • RGB testing.
  • Grip sensor testing.

10. Displays the MAC Address

USSD code: *#*#232338#*#*

The Media Access Control (MAC) address is a unique identifier assigned to each computer that allows it to be identified on a network. MAC spoofing is the act of disguising a device’s MAC address to gain unauthorized access to a network. You can view the MAC address on the device, and confirm it against the list of addresses allowed on your network, to ensure that it is correct.
