60+ Best Secret Codes To Explore Android 2020
As all users of Android devices know, in this system, we can access a limited series of information through the settings of the phone, which allows us to know some data of the operating system and the device, and at the same time gives us the possibility of make some configurations according to the use we are going to give it.
However, there are also a series of codes, which for many are a great secret, that just by entering them in the Android Smartphone or Tablet allows us to explore our device in more depth.
These codes also give us the possibility of accessing extra functions to carry out advanced configuration, since we take into account that they were created as a tool for manufacturers and operators.
It should be noted that the secret codes of Android can vary depending on the brand and model of the device, and even some of these codes may not work as expected on certain computers.
That is why below we present you a great list of secret codes that apply to certain Android phones, but that you can try in other brands and models because perhaps they can also work.
It is important to note that to carry out this process, we must enter any of the codes that will be shown in the list below, through the numeric keyboard of the application with which we usually make calls.
After that we must wait a few seconds for the code to be loaded, and we will see what happens. If nothing happens, it is simply because the entered code is not compatible with the device.

What are USSD codes
Basically the USSD codes, a word that comes from the English language that means “Unstructured Supplementary Service Data”, or in Spanish “Unstructured Supplementary Data Service “ is a protocol or standard that allows the sending of data through GSM cell phones, which is quite similar in certain characteristics and implementation to the well-known SMS. It should be noted that these codes are also known as “Quick Codes” or “Function Codes”.
Among the different tasks in which we can use these USSD codes usually are the possibility of being used for WAP navigation , information search services based on interactive menus or based on location, callback services in prepaid services and mobile money services, we can also find it as part of the configuration of the device in the network of the of the mobile phone operator.
These USSD codes were originally used by technical support technicians to perform tests and diagnostics , but that does not mean that we can use them to obtain all that valuable information for our own benefit.
Differences between SMS and USSD
We spoke above that the USSD code system has many similarities to the SMS message system, but also of course differences, small, subtle, but that make them not the same technology.
As an example, USSD messages can be up to 182 alphanumeric characters in length per message. Another fundamental difference is that USSD messages create a real-time connection during a USSD session . Furthermore, said connection remains open, allowing a two-way data stream exchange to be carried out.
Another fundamental difference from USSD codes is that sent messages cannot be stored for later forwarding, which means that if they cannot be delivered right then, they are discarded.
