Owning a modern Xiaomi smartphone involves not only the use of pre-installed features, but also the ability to fine-tune the system to suit your needs. Often users are faced with the need to connect the device to the computer for deep diagnostics, installing specialized applications or flashing, it is in these situations that standard user settings become insufficient, and you need to activate hidden system settings.
The main tool for interacting with the software code of the Android operating system is debugging mode. Many people mistakenly believe that this feature is only necessary for programmers, but it can also be useful for the average user to control a phone from a PC or restore access to data. In the MIUI interface and the new HyperOS shell, this process has its own features that you need to know about.
Before you start activating hidden functions, itโs important to understand that you get advanced access to device management. USB debugging allows a computer to send commands to your phone, read system logs, and manage the file system at a deep level. Without proper preparation and understanding of the risks, such actions can lead to unstable gadget operation or data loss.
Why you need a developer mode on Xiaomi
The hidden Developer Menu in the MIUI shell contains a set of tools designed primarily for application testing and debugging, but the functionality of this section goes far beyond programming, activating these settings opens up access to control animation speed, background process limits and, most importantly for our topic, debugging permission.
One of the key features is the ability to create full account-based system backups, which is not available in standard mode, and you can force applications to the memory card if the phone model supports it, or change the minimum interface width to increase the number of display elements on the screen.

Use Developer Mode to speed up the interface: reduce the scale of window animation and transitions to 0.5x so that the smartphone feels faster.
It is worth noting that the constant activation of certain functions can negatively affect autonomy. For example, the background work of the debugger consumes additional CPU resources. Therefore, after completing the necessary manipulations with files or settings, access to the developer mode is recommended to be limited.
How to activate the menu for developers
The first and mandatory step before enabling debugging is to activate the most hidden settings section. Unlike some other manufacturers, Xiaomi requires a certain action to unlock this menu. The process is simple, but requires careful calculation of clicks.
You need to go to the basic settings of the smartphone and find the section "About the phone" here is information about the version of the system, the processor and, most importantly, the version of the shell MIUI. It is on the line with the build number you need to apply a series of quick touches.
โ๏ธ Activation of the developer mode
After the seventh press, the system will request the password to unlock the screen or PIN-Upon successful entry, you will see a toast notification stating "You are now a developer!).
โ ๏ธ Warning: If nothing happens after ten taps, check if Extended Mode is enabled in the special feature settings. Sometimes it can conflict with quick touches on the screen.
Enabling debugging over USB and fixing errors
Once you successfully activate the hidden menu, a new item will appear in the settings list, which may be called "Additional" depending on the firmware version, but most often it is immediately in the root settings menu or in the "Advanced Settings" section. We need the "Developers" item.
Inside this section, you need to find the USB Debugging Tool. In some versions of HyperOS, this item may be hidden inside the Debugging submenu. Activating this slider triggers a service that allows the computer to interact with the phone via the Android Debug Bridge (ADB) protocol.
When you first connect the cable to your PC after you turn on this feature, you'll see a dialog box on your smartphone screen asking for debugging permission. RSA-Always check if you are connecting to a trusted device before you click OKยป.
Settings โ For developers โ Debugging by USB โ EnableThere is also a Wi-Fi Debugging feature that allows you to connect to a device without a cable, but it only works after initial setup via USB.This is convenient for wirelessly transferring large amounts of data or testing applications in real time.
Permissions setting and connection security
Just turning on the switch isn't enough to work properly. Android security requires authorization confirmation for each new computer. If you plan to use your phone to work with your PC, you need to set the security settings in the developer menu correctly.
Note the item โDebugging over USB (Security settings)โ: In newer versions of MIUI, this switch is often turned off by default and requires waiting 10 seconds after activation, this is done to protect against viruses that may try to automatically access data when charging in public places.
- ๐ Permission RSA: Confirm your connection only on devices you trust.
- โ๏ธ Configuration USB: Select the mode of operation (MTP, PTP, MIDI) for correct display of files.
- ๐ฑ Lock: Do not leave your phone unlocked when connecting to someone else's PC.
What is ADB and why is it needed?
If you plan to use your phone for development or deep modification, you should also pay attention to the item โSelect an app for a dummy locationโ, which allows you to test geo-dependent services, emulating travel elsewhere in the world.
Solution: Computer can't see phone
One of the most common problems after debugging is the lack of response of the computer to connect the device. Even if the developer mode is activated, the drivers may not install automatically, or the cable may be faulty.
First of all, check the cable itself. Many cables are only for charging and do not have data lines. Use the original Xiaomi wire or a quality analogue with the labeled (data transfer). USB-port, preferably directly to the motherboard, bypassing the hubs.
| Problem. | Possible cause | Decision |
|---|---|---|
| The phone is just charging. | Faulty cable | Replace cable with quality cable |
| No reaction to PC | No driver installed. | Install Mi PC Suite or ADB drivers |
| RSA request doesn't appear | Debugging mode is off. | Check the switch in the developer menu |
| The device is defined as unknown. | Driver conflict | Update drivers in Device Manager |
In some cases, resetting debugging settings helps. In the Developer menu, find the option "Cancel USB Debugging Permits" and press it. Then reconnect the cable and confirm the request on your phone screen.
Features of work in the shell of HyperOS
With the release of the new HyperOS operating system, Xiaomi made a number of changes to the menu structure and logic of system functions. Although the basic principle of enabling debugging remained the same, the visual design and location of some switches changed.
HyperOS adds more control over permissions, and when you try to connect a new device, the system may require more than just confirmation. RSA-It's also key, but it's also additional authorization through Mi Account if you have "Find Device" enabled, which increases security, but makes it harder for newcomers to log in.
The interface of the developer menu has also changed, some items have been regrouped, and the functions related to the network and Bluetooth have been moved to separate subsections for convenience. If you can't find the right option, search by settings by entering the keyword "Debugging".
โ ๏ธ Note: In HyperOS when enabling debugging by USB You can activate the default Charging Only mode. Don't forget to manually switch mode. USB In the curtain notification on "File transferยป.
Safety and risks of using debugging
Using the developer mode and debugging over USB opens up opportunities, but also creates potential vulnerabilities. The debugging mode device becomes accessible to any commands from a connected computer, which can be exploited by attackers when physically accessed.
Never leave your phone connected to public charging stations in debugging mode. USB-Not only can you charge the battery, but you can also read data, install malware, or lock the device. In public places, use Charge Only modeยป.
- ๐ซ Public Networks: Avoid connecting to unknown PCs in debugging mode.
- ๐ Screen lock: Always use a strong password or biometrics.
- ๐๏ธ Visual Control: Watch the screen when connecting to other devices.
๐ก
USB debugging is a powerful tool that should only be enabled for as long as necessary. The rest of the time, keep this feature off for maximum security.
If you've finished working with files or setting up a system, it's recommended that you turn off the developer mode, and you just need to put the master switch at the top of the menu in an inactive state, which will hide the menu from the main settings and close the ports to external access.
