These are all the secret Android codes that you can unlock on your Xiaomi

If you like to mess around and you are one of those people who want to know in depth all the secrets of your mobile, you must know the secret codes of Android. They serve, for example, to discover if your Xiaomi mobile is original or fake , as well as being very useful for performing different performance tests on smartphones and tablets.

Of course, we recommend using them with some caution, since some of the codes can be used to delete applications, reset functions or turn off the phone.

Secret codes to know your Xiaomi in depth

For our terminal there is a complete suite of hidden information that we can reveal. And for this we can do it in two ways: either by going to an application or by writing the assigned code by hand.

PhoNetInfo , for example, is an application that shows detailed information about our terminal, from the installed firmware version to the status of the sensors , temperature and battery status, details about our network connection, CPU, GPU, RAM, etc.

A kind of CPUz or Speccy for mobile phones that brings together a large amount of information in the same space to learn more about the health status of your mobile . There are currently two versions, one free and one paid, known as PhoNetInfo PRO .

Within this app we can access the ‘Secret Codes’ section, a compilation of codes that we can type with the numeric keypad of the ‘Telephone’ app and discover all the secrets of our terminal. The vast majority are written using asterisk and hash, that is, * # * # opening and # * # * closing , within certain numberings that act as unlocking functions.

But if you don’t want to use any third-party application you can always write them by hand, using the ‘phone’ application .

Let us bear in mind that, depending on the manufacturer and the version of Android installed on our smartphone, some codes will work and others will not. If they are not compatible, they will simply disappear , nothing happening on the system.

Here’s a general breakdown of most advanced codes.
