42 Android secret codes and hacks you need to know

USSD codes are hidden codes that allow you to access certain functions on your mobile phone without having to go through your settings. These feature codes look like a combination of numbers and symbols and normally begin with an asterisk (*) or a hashtag (#).

Android secret codes are programmed into your SIM card or mobile phone number and allow your smartphone to communicate with your mobile network operator. You can use these codes to do things on your smartphone faster and thus become a more efficient user.

In this list you will find the most common secret codes that work on most Android phones and some of them even work on iPhone. Depending on the mobile phone manufacturer, the Android version your phone is running, your region and phone apps, some codes may not work. This may be the case if you are using a dual SIM smartphone. There are also codes that are specific to different carriers and different phone models, so they will only work for them.

The only way to find out if a particular code works for you is to try using it on your Android phone.

The USSD codes can actually simplify your daily smartphone use. You don’t have to scroll through your settings looking for a specific feature anymore. Instead, follow these quick steps.

1. Open your smartphone’s dialer (Phone app). It is usually located on your main screen.

2. Enter the USSD code you want to use.

3. Some codes will start loading automatically, for others you have to choose Calls button.

These USSD codes are the most important of all. Use these security codes if your phone is not working properly and if you suspect a third party affecting your handset. Using them will either reassure you or make you act faster if you find that hackers are tampering with your device.
