Xiaomi’s current smartphones, which run on the MIUI shell or the new HyperOS, are powerful devices that hold huge potential for advanced users. The standard interface we see every day is limited by a lot of prohibitions designed to protect the inexperienced owner from random errors. However, behind this facade lies a special section known as the developer menu, access to which opens the door to deep system setup.
Activating this hidden partition allows you to control the processor’s performance, change the animation speed, enable USB debugging to connect to your computer, and perform many other technical manipulations. Many users are looking for a way to unlock hidden settings on Xiaomi without losing warranty, and the answer lies in standard system functions that are simply hidden from prying eyes. Enabling these options does not require root rights or complex software, just know the sequence of actions.
In this article, we will discuss in detail the process of activating the engineering menu on various models of the brand’s smartphones, including Redmi and POCO. You will learn what parameters can be changed to speed up the interface, how to properly configure debugging for file transfer and what risks are associated with careless handling of system settings.
Why you need a developer menu and what opportunities it gives
The developer section is not just a collection of obscure switches, but a powerful diagnostic and optimization tool, and its main purpose is to enable engineers and testers to debug applications and test the system early, but can also be of tangible benefit to the average user, especially if the device is starting to run slower or requires specific connectivity settings.
One of the most popular features is USB debugging, which allows the computer to interact with the smartphone at a deep level, transferring not only files, but also control commands, which is necessary for installing applications outside the official store, using emulators, working with adb commands, and even flashing the device in case of critical failures. Without activation of this mode, many advanced scenarios for using the gadget become impossible.
And then there's settings that affect how you see the interface, and rescaling the DPI font, turning off hardware acceleration, or changing the behavior of windows, all of which are at your disposal, and users often turn to these settings to make the interface more responsive or adapt it to their own needs.
- 🚀 Speeding up: Changing the scale of animations makes transitions between screens instantaneous, creating the illusion of a faster processor.
- 🔌 Connection management: Bluetooth codec settings, configuration USB Modem modems for advanced users.
- 🐞 Diagnostics: displaying processor load in real time and analyzing memory usage by running applications.
It is important to understand that interference with the system always carries certain risks. Incorrect settings can lead to unstable operation of individual applications or even to a cyclical reboot of the device. That is why access to this partition is hidden by default, and the system requires the user to consciously confirm their actions through multiple clicks.
Step-by-step instructions: how to activate the developer mode
The process of unlocking hidden menus on Xiaomi, Redmi and POCO devices is unified and does not require a connection to a computer or the use of third-party software. All actions are performed directly in the smartphone interface. Before starting, make sure that the device is charged at least 20-30% to avoid sudden shutdown during the manipulation of system files.
The first step is to open the main settings menu, find the gear icon on your desktop or in the notification curtain, and at the top of the list you'll see your model name and operating system version, and that's the area called "About the Phone" that's key to logging into the engineering menu, and on some firmware versions, it might be called simply "About the Device."
Inside the About Phone section, you'll need to find a line called the MIUI Version (or HyperOS Version), which is the line you need to run a series of quick taps on. You don't need to press a button or use special gestures, just tap your finger quickly on the version name. It usually takes 7 to 10 taps.
☑️ Activation algorithm
When you click, the system will pop up notifications, counting the remaining steps before activation, and you will see messages like, "There are 4 steps left to turn on the developer mode." Once the limit is reached, a pop-up notification will appear on the screen "You are a developer!", and basically the settings menu will appear a new item.
⚠️ Warning: If nothing happens after 10 taps, you may have a global version of the limited firmware installed on your device or you may be pushing too slowly.
Once you've successfully activated, go back to the main settings menu. Scroll down to the bottom of the list where the "About Phone" item was previously located. Now there should be a new line "Additional or Advanced Settings" that will contain the desired partition. In new versions of HyperOS, the path may be slightly different and may be in the "Extended Settings" section" →"For developers".
Where is the developer menu in different versions of MIUI and HyperOS
The interface of the MIUI shell and the new HyperOS are constantly evolving, changing the location of certain items. This often causes confusion among users who are switching from old device to new or updating over the air. Understanding the logic of the menu structure will help you find the right switches faster, regardless of the software version.
In the classic versions of MIUI 12 and MIUI 13, the path was usually as simple as possible: after activating in the About Phone section, a new Developers item appeared at the bottom of the list of basic settings, immediately after About Phone. This was intuitive and easy to find. However, with the release of MIUI 14 and the transition to HyperOS, the company decided to structure the menu more strictly, hiding the technical options deeper.
In current builds, the search algorithm has changed. Once the mode is activated, you need to go to the Additional Settings section (sometimes called simply "Advanced"). This section is usually at the bottom of the list of basic settings, often next to "Security" or "Special Capabilities." Inside this subsection, the desired "Developers" item is hidden.
If you can't find it even after you activate it, you can search by settings. Click on the magnifying glass at the top of the settings screen and type "developer" or "developer." The system will highlight the menu item you want, allowing you to go to it with a single touch, which is a universal way that works on all versions of firmware without exception.
| Shell version | The path to the menu | Location of the "On the telephone" item |
|---|---|---|
| MIUI 11-12 | Settings → For developers | At the bottom of the list. |
| MIUI 13-14 | Settings → Additional settings → For developers | At the bottom of the list. |
| HyperOS 1.0 | Settings → Advanced settings → For developers | At the top of the list (first item) |
| Android One (Mi A) | Settings → System → For Developers | At the bottom of the list. |
It is important to note that on some regional firmware versions (for example, for China), item names may differ. In the Chinese version of CN ROM, the section may be called "" (Additional settings), and the developer's item itself -". The visual style of the icons may also vary, but the logic remains the same.
Configuring debugging over USB and working with a computer
One of the main reasons users activate the hidden menu is to enable USB debugging, which allows the computer to send commands to the phone and receive responses, which is used to install applications (ADBs), take system screenshots, log bugs, and more. Without debugging enabled, the computer sees the phone only as a media device or charger.
To activate this feature, log into the developer menu and find Debugging via USB. Switch the switch to the active position. The system will immediately issue a serious security risk warning, explaining that in this mode the device becomes vulnerable to attacks when connected to unknown computers.
When you first connect a smartphone with debugging enabled to a computer, a request for debugging permission from that computer will appear on the screen of the mobile device. RSA-Key and sentence "Always allow debugging from this computer?". Be sure to tick and click "Allow", otherwise each connection will have to confirm access again, and some programs may not work.
For users engaged in system modification, an important parameter is the Factory unlocking (OEM Unlocking. This item is also on the developer menu, and activating it allows the bootloader to go into unlock mode, which is necessary for the installation of custom Recovery (TWRP) Without this switch, it's not officially possible to unlock the bootloader without flashing the device.
⚠️ Attention: Including debugging by USB If you have a lost or stolen phone, you give an attacker full access to your data. Never leave this mode on permanently unless you're using it right now.
You can also set the behavior in this section. USB-Default connection. Punkok configuration USB By default, you can choose how the phone will behave when connected to a PC: as a charger, as a drive (MTP), photo-transmitter (PTP) or MIDI-It eliminates the need to choose the mode in the notification curtain every time.
Optimization of the interface: scaling and animation
The developer menu allows you not only to customize the connections, but also to change the visual perception of the system. Many users notice that over time the phone begins to seem "slow." Often this is not due to a drop in the performance of the iron, but to long animations of transitions. By reducing their duration, you can make the interface more responsive.
Find the drawing section inside the developer menu, and you're interested in three things: "Scope of window animation," "Scope of transition animation," and "Scope of transition animation." They're set to 1x by default. Changing them by 0.5x will cut the time of all visual effects by half. The interface will seem much faster and sharper.
Another useful feature is changing the density of DPI (dots per inch). The Smallest width allows you to rescale the interface elements. Increasing the value will make elements smaller, which will fit more information on the screen, and reducing larger. The standard value for most Xiaomi smartphones is in the range of 360-411 dpi.
Be careful when changing the DPI. Too high can make text unreadable, and too low can break the layout of some applications that can not adapt to non-standard resolutions. If the screen has turned black after changing the values or the interface has stopped responding, try quickly pressing the combination of the on and volume buttons (if it works) or wait for a timeout, but it is better to remember the original value in advance.
- 🎨 Smoothing: the option "Smoothing" allows you to forcibly turn on antialiasing for fonts and graphics, making the picture clearer, but loading GPU.
- 📱 Tablet mode: a strong decrease DPI It can turn the phone interface into a tablet-like one by changing the layout of the menu.
- ⚙️ Hardware acceleration: forced activation GPU-rendering 2D-graphics can help with old games, but will increase battery consumption.
It also has a feature called Touch Show, which is when you turn it on, you get a white circle at the touchpoint of your finger, which is really useful for creating screencasts, training videos, or just checking the responsiveness of the touchscreen in different areas of the screen.
Management of memory, processes and background tasks
For advanced users and application testers, control over RAM and background processes is critical. In the Xiaomi developer menu, there is an "Applications" section where you can control the behavior of the system when resources are scarce.
