Android: List of secret codes to access hidden information

Android secret codes are not just used to play with our smartphones, they can also be useful for accessing information about our device, for development, or for performing actions quickly.

What are secret codes on Android?

USSD codes

They are often confused with secret codes on Android. First of all, USSD stands for Unstructured Supplementary Service Data. It is a protocol that allows information to be sent via GSM, 3G or 4G networks. The idea is to be able to trigger actions remotely, by sending a specific code for each.

To enter them, just proceed directly from the call application pad. They usually begin and end with a sharp or asterisk. However, some commands are country/operator exclusive and the rest of them have been standardized and are available worldwide. These codes allow for example to program a call transfer.

In fact, you can request information from your operator’s servers through them, that’s all. They work at the same level as the secret codes specific to Android, which is why it is easy to confuse them.

The hidden side of USSD codes

This is less true now, but at one time some experts sounded the alarm bells about the possibilities of exploits on Android. The protocol can be used for malicious purposes by applications or even sites.

At the end of 2012, for example, a scandal hit the flagships of Samsung. They were vulnerable to a factory reset code, which could be launched directly from a web page.

Android secret codes

They have a peculiarity, they always end with a sharp but usually begin with an asterisk. Unlike USSD codes, you do not need to be connected to the network to activate them since they act directly from and on the Android system.

They are actually stored in system files and depend on the version installed on the smartphone. Many codes have become obsolete with the transition to recent Android versions. After the arrival of these versions, some codes have been deleted, others implemented.

In addition, some manufacturers have also added their exclusive touch with new codes on some of their terminals.

Warning: These codes can cause you to lose your data or even render your smartphone unusable. Most of the menus are in English and include terms that are obscure or even incomprehensible to ordinary people. Follow the most basic rule in DIY: If you don’t know exactly what you’re doing, don’t do it.
