Modern Xiaomi, Redmi and POCO smartphones running MIUI or HyperOS hide many useful features for advanced users. The standard settings menu offers only basic options, but for a thin configuration, debugging applications or speeding up the interface, you need access to a hidden partition. This is where the tools to control the behavior of the Android operating system at a deep level are located.
Activating this partition does not require root rights or complex software, but it gives the user control over parameters that are usually reserved for engineers. Enabling these options can significantly change the experience of interaction with the device, allowing, for example, to speed up the opening of windows or prevent the system from completing background processes. It is important to understand that interference with system settings requires caution, since incorrectly changing parameters can lead to unstable operation of the gadget.
In this article, we will discuss in detail the process of activating the hidden menu, consider the purpose of the main parameters and answer frequent questions that arise from owners of Chinese brand equipment. You will learn how to properly configure debugging to connect to a computer and which animation parameters are better to change to visually speed up the smartphone.
Why you need access to engineering settings
The main purpose of the hidden menu is to give app developers tools to test and debug their software, but ordinary users can also find many useful features here, such as the ability to force a dark theme to be included in applications that do not officially support it, or to change the font size in system interfaces beyond standard restrictions.
One of the most popular features is animation management. Standard MIUI transitions can seem slow on budget models. By changing window scaling rates and transition times, you can achieve a more responsive and faster interface without actually improving CPU performance.
- 🚀 Speeding up the interface by changing the speed of animation windows and transitions.
- 🔌 Initiation of debugging USB for transferring files, installing applications from PC or using ADB.
- 🌙 Forced activation of dark theme for all system elements and third-party applications.
- 📍 Accurate geolocation setting and location simulation for service testing.
⚠️ Note: Changes in settings associated with minimum screen width (DPI), If you accidentally set a value too high and the menu is unavailable, only a complete reset of the phone's settings will help.
Another important feature is control of background processes: Android aggressively unloads applications from memory to save battery power, which sometimes interferes with the work of messengers or navigators. In a hidden menu, you can limit the number of background processes or, conversely, prevent the system from completing them, although this can increase energy consumption.
Step-by-step activation instructions for MIUI and HyperOS
The process of enabling hidden capabilities on Xiaomi smartphones is standardized and takes only a few seconds. You do not need third-party programs or a computer connection. All actions are performed directly in the settings menu of your device. The algorithm is the same for most models, including the Redmi Note, Poco X and the flagship Mi series.
To start, you need to go to the main settings menu of your smartphone. Find a section that is usually called About Phone or My Phone. This is where you find the basic information about the model, operating system version and build number. In some versions of firmware, this item may be at the top of the list or in the General Settings submenu.
The key element is the line "version" MIUI» or "Version" OS». It needs to be pressed quickly several times in a row. It usually takes 5 to 7 taps. After a few taps, a countdown pop-up notification will appear, telling you how many times you still have to click to become a developer.
Settings → About Phone → Press 7 times on "Version MIUI"Once the click limit is exhausted, the system will give a message saying “You are a developer!”. From now on, a new option will appear in the main settings menu, usually under “Additional” or “Extended Settings” section. If you use HyperOS, the logic remains the same, but the visual design of the menu may differ slightly.
☑️ Verification of mode activation
It is worth noting that some global firmware versions may require a Mi Account password to confirm actions, a security measure implemented by the company to prevent accidental changes in critical parameters by children or inexperienced users.
Basic parameters for system setting
Once you log into the Developer Menu, you have a vast list of options that you can see, not all of which are needed by the average smartphone owner, but a few sections that deserve special attention, and at the top of the list are often debugging and error reporting switches that you can ignore if you're not programming.
Of particular interest is the Drawing section, which is where you find window animation, transition animation, and animation duration, which are set to 1x by default, and changing this to 0.5x makes the interface visually faster and more responsive, and it's the safest and most efficient way to speed up an old smartphone.
You can also turn on the "Show Touch" option in this section, which will show a white circle on the screen when you touch your finger, which is useful when creating screencasts or training videos so that viewers can see exactly where you are clicking on the display.
- 🎨 Scaling fonts and interface elements for people with visual impairment.
- 📊 Display the current processor boot and memory in real time.
- 📱 Emulation of screen cutout (bangs) to check the compatibility of applications.
- 🔋 Detailed statistics of energy consumption by each running process.
What is the limitation of background processes?
For example, changing the minimum screen width (DPI) changes the pixel density, increasing this value will make elements smaller but will accommodate more information on the screen, but some buttons may become too small to be easily pressed.
Configure debugging over USB and work with ADB
One of the main reasons users activate the hidden menu is to enable debugging over USB, which allows the computer to gain full access to the smartphone system to execute commands, install applications bypassing standard restrictions, or restore the system in case of failure.
To activate this function in the menu "For developers" you need to find the switch "Debugging by" USB» And activate it. It will alert you to potential security risks. When you first connect to your computer, you'll see a request for debugging confirmation from that computer, where you'll need to check the data. RSA-key.
Using Android Debug Bridge (ADB) opens up a wide range of possibilities: removing system debris (bloatware) that cannot be removed by standard means, creating full backups of applications with data, as well as screenshots of the entire screen on devices without such an integrated feature.
| Parameter | Description of function | Recommended value |
|---|---|---|
| USB debugging | Allows data exchange from PCs via ADB | On (if necessary) |
| Wi-Fi debugging | Wireless connection of the debugger | Off (saving battery) |
| USB configuration | Port operation mode when connecting | File Transfer (MTP) |
| Charging via USB | Only charging without data transfer | Depends on the task. |
When working with ADB, it is important to install the right drivers on your computer. Xiaomi devices often require specific drivers that can be found in the official Mi Unlock snail or downloaded separately. Without the right drivers, the computer will not recognize the smartphone in debugging mode.
💡
When connecting your smartphone to a new computer, always check the pop-up window on your phone screen. If you accidentally hit Cancel or Always Forbid, you will have to reconnect the cable and request permission.
There is also a Wi-Fi Debugging feature that allows you to connect to a device without cable if both gadgets are on the same network.This is convenient for wireless transfer of large amounts of data or debugging, but requires pre-configuration through the same network. USB-cable.
Memory and background management
Algorithms of working with memory in MIUI The system seeks to free up resources for the current active application, ruthlessly unloading from memory everything that was previously running, which often leads to the fact that the music players are silent and the navigators lose their memory. GPS-roll-up.
In the developer section, you can find the item "Background Process Limit"; it is not installed by default, which means automatic system management; the user can manually set a restriction, for example, "No more than 4 processes." This can be useful on devices with low RAM (3-4 GB) to prevent the system from completely freezing when multitasking.
However, if you have a flagship device with 8 or 12 GB of memory, setting tight limits can be counterproductive.Modern processors and Android optimizations are able to efficiently manage memory without user intervention. Artificial restriction will force the system to reboot applications more often, which will increase their startup time and power consumption by the processor.
- 🧹 Forced stop of all background services via the "Complete all processes" menu".
- 📉 Real-time display of active services for load monitoring.
- ⚙️ Adjust system behavior when there is a lack of free memory.
- 🔒 Blocking specific applications in memory (requires third-party utilities).
Also available here is the Do Not Save Action function, which, if enabled, will destroy the activity of the application as soon as the user leaves it, a memory-saving mode that in everyday use makes multitasking impossible, as the applications will not retain their state.
To diagnose memory problems, you can turn on the option “Show running services” in the corner of the screen, a counter will appear that shows the number of active processes and the amount of RAM they are using, which helps you understand which application is consuming the most resources at the moment.
Possible problems and ways to solve them
While the hidden menu is useful, careless handling can backfire, with the most common problem being rescaling the interface (DPI) to values where text becomes unreadable or controls move off the screen.
If you change the Smallest width setting and the interface becomes unusable, don't panic. Try quickly opening the camera or other app that can reboot the current interface process. If that doesn't work, the only way out is to reset the phone to factory settings, as you can't access the settings menu through the non-working interface.
⚠️ Warning: Never turn on options related to StrictMode or debugging GPU, If you don't understand their purpose, it can cause the device to heat up very much and cause a sharp decline in autonomy.
Another common problem is the inability to include debugging on USB. This may be related to damage. USB-cable, port malfunction or lack of necessary drivers on the PC. Also, some global firmware requires an active Internet connection to verify access rights when the developer mode is first activated.
Sometimes the "Developers" item may disappear from the menu by itself after the system update, in which case the activation procedure (7 taps according to MIUI) must be repeated.
💡
Developer mode is a powerful tool, but it's not designed to be used by the average user on a regular basis: turn on only the desired features and return the standard values after completing the tasks.
In case of critical errors, such as cyclic restart (bootloop) after changing system parameters, only flashing the device or entering Recovery mode to reset data will help.
