How to find my links in Xiaomi phone: hidden features

Many Xiaomi smartphone owners are wondering how to find hidden system links in their device. It's not about ordinary Internet addresses, but about special engineering codes and deep settings that allow you to control the hardware of the phone at a low level. Understanding where to look for these parameters opens up access to advanced diagnostics, which usually do not show on the standard menu.

However, access to these features requires caution: In the MIUI operating system and the new HyperOS, the paths to this data are often hidden from the eyes of the average user to protect against accidental changes, and improper use of such tools can lead to malfunctioning of communication modules or resetting important parameters.

In this article, we will discuss all available ways to search for system links, from simple USSD-You will learn how to safely activate the hidden menu of the developer and what commands you should use to check the current state of your device.

Under the term "links" in the context of a mobile operating system often understand internal links URI-address USSD-These elements allow you to interact directly with the firmware of the device, bypassing the graphical interface. In Xiaomi smartphones, such links are often used by engineers in the factory to test components before going on sale. You can find them in different sections, but most often they're hidden in the system applications Phone or Settings, and using these tools, you can access information that the average user rarely sees in everyday life. CIT (Customer Integration Test: This is a special section that contains diagnostic tools for screen, speaker, sensor and camera screen testing.

Xiaomi’s standard menu can block some codes if the Phone app is replaced with a Google or other manufacturer’s counterpart. In this menu, you'll find a list of all the components of the phone, and by clicking on the list, you'll trigger an automatic check, which is useful if you want to know if the accelerometer is working or if the noise reduction microphone is working. 📱 Backlight – check the brightness and operation of the display backlight. 🔊 Receiver – Testing the Speaker at the Top. 📷 Front Camera – Launching a front-facing camera to check the matrix. 📡 GPS — check of satellite reception and operation of the navigation module.

If you want not hardware tests, but system settings and debugging links, you'll need to activate developer mode. This is a standard Android feature that's in the shell.

For more advanced users looking for links to system files or configuration data, there is a file manager. However, the standard Xiaomi Explorer by default hides system partitions. You will need a third-party application with access rights or use ADB-In the Android file system, the links to the apps and their data are stored at the root. /data/data/ It contains the settings of all installed programs. /system/priv-app/ It stores system applications that could disrupt the phone, and access to those parts without root rights is restricted. 💡Direct editing of system files is possible only if you have superuser rights. Without root access, you can only view the folder structure, but not change the configuration files. If you connect your phone to your computer in debugging mode, you can see log files that contain links to running processes.

Network diagnostics and IMEI Cellular codes are particularly noteworthy, and they allow you to check the status of registration in the network, signal quality and integrity. IMEI-Entering *#06# instantly displays hardware identifiers. This is the basic link to the modem hardware information. 4G and 5G It uses code ##4636##. It opens the test menu, where you can see which tower the phone is connected to, the signal level in dBm and the type of network. ⚠️ Note: In the phone testing menu, do not change the "Preferred Network Type" to prefixed values "NR" or "LTE only" unless you are sure that your operator supports these standards. This can lead to the complete disappearance of the network and the inability to make calls. Sometimes users are looking for ways to reset the network settings through hidden links.

Why the code ##64663## Does it not work on my Xiaomi? In some global firmware versions or on newer versions of HyperOS, access to the engineering menu can be limited or changed. Try entering the code in the Xiaomi Phone app instead of in a third-party typer. Is it dangerous to reset the settings in the engineering menu? Yes, it's dangerous. Reset can remove the calibration of the sensor, Bluetooth address, or IMEI. It's very difficult, sometimes impossible, to recover this data software without special hardware?
