Modern Xiaomi, Redmi and POCO smartphones are based on the Android operating system, which is originally intended for the mass user. However, behind the standard interface hides a powerful layer of system settings that are only available after activation of special mode. Many device owners face the need to enable debugging over USB, change the animation speed or reset network settings, but can not find the corresponding item in the standard menu.
By default, the developer menu is hidden from the eyes of the average user, and this is done specifically by Google and MIUI engineers to prevent accidental changes in critical parameters that can lead to unstable operation of the gadget. To access advanced features, you need to perform several consecutive actions that are not obvious when you first get acquainted with the device.
In this guide, we will discuss in detail how to activate the hidden partition, what risks it carries and what parameters should be changed to speed up the smartphone. USB-debugging for connecting to your computer and what animation settings will help visually speed up the interface of your device without losing performance.
What is the need for a developer menu on Xiaomi
The main purpose of this section is to provide tools for testing applications and debugging code by programmers, but users can also find useful features here, such as rescaling the DPI to allow more elements to be displayed on the screen, which is critical for owners of tablets or smartphones with a large diagonal, and you can force a dark theme to be included here for applications that do not officially support it.
Another important function is back-end management: In the background limit section, you can limit the number of applications running simultaneously, which should theoretically save battery power and RAM. USB debugging opens up access to computer utilities for deep cleaning of the system, installing custom recavators or flashing the device in case of software failures.
It is worth understanding that rash change of parameters in this section can lead to incorrect operation of touch screen or failures in data transfer. MIUI has additional protections, so some items can be blocked or require re-authorization through Mi-account at each login.
Step-by-step instructions for activating the hidden mode
The process of enabling hidden settings on Xiaomi devices is standardized, but requires care. You do not need root rights or a connection to a computer at this stage. All actions are performed directly on the smartphone screen through the standard settings application.
First, open the main menu and find the Settings icon, which is usually located at the top of the list or in the folder with system utilities. Next, you need to go to the very first section, which is often called About the Phone, and this is where all the technical information about your device, including the version of the processor, memory capacity and the operating system version, is contained.
☑️ Activation algorithm
Inside the About Phone section, you need to find the MIUI Version (or the Clean Shell Android Version) string. Next to the version name, you usually have the build number in brackets or small print. You need to quickly click on this area seven times in a row. After the fifth or sixth press, the system may ask you to enter the screen unlock password or pattern lock. After successful entry, a pop-up notification will appear that you have become a developer.
⚠️ Note: If nothing happens after seven clicks, check if you have Advanced Mode enabled in the theme settings. In some customizations, the line can be hidden or renamed.
Where is the tab after inclusion
Once you activate the settings interface successfully, nothing visually changes immediately. The new menu doesn't appear on the home screen, it integrates into the system settings structure. To find it, go back to the Settings root menu and scroll down the list.
Where the list ended before, a new item has now appeared, Additional Settings (on some firmware versions it may simply be called Advanced Settings). Once you enter this section, you will see a long list of options, and near the end of the list you will find the desired Special Features (or Developers).
The path to the menu may vary slightly depending on the HyperOS or MIUI shell version:
- 📱 Standard path: Settings → Additional settings → For developers.
- 🔍 Through Search: Enter the phrase “Developer” or “usb” in the settings search bar".
- ⚙️ Alternative path (older versions): Settings → Advanced settings → For developers.
If you can't find the item even after activation, try clearing the Settings app cache or restarting the device. Sometimes the system takes time to index the new menu.
Setting up USB-debugging and working with PC
One of the main functions of this section is USB-It allows the computer to have full access to the file system and Android commands through the protocol. ADB (This is necessary to install applications not available in the Play Market or to restore the system through Fastboot.
To activate, find the USB Debugging Switch and turn it on. The system will issue a security risk alert, confirm the action. When you first connect to your computer, a request will appear on the smartphone screen for debugging permission from that computer. You must tick Always Allow from that computer and press OK.

💡
If your computer can’t see your phone, try replacing it. USB-Cheap cables often only support charging and don't have lines to transmit data.
Optimization of the interface and acceleration of work
Owners of Xiaomi smartphones often complain about excessive animation, which visually slows down the interface. In the developer menu, you can change the speed of playback of window animations, which will make the transitions between the screens more sharp and faster.
Find the Drawing or Animation block. You're interested in three things: Window animation, transition animation, and animation duration. They're set to 1x by default. Change each to 0.5x or even Off.
This setting doesn't increase the actual performance of the processor, but subjectively, the device starts to run much faster, and you can find the function "Do Not Activity" here, if you turn it on, the system will completely close the application as soon as you leave it, which will free up RAM, but can lead to more frequent reboot of applications when you restart it.
| Parameter | Standard value | Recommended value | The effect |
|---|---|---|---|
| Window animation | 1x | 0.5x | Acceleration of opening/closing applications |
| Animation of transitions | 1x | 0.5x | Quick switching between screens |
| Duration of animation | 1x | 0.5x | Reducing waiting time for action |
| Background process | No restrictions. | No more than 2-3. | Saving RAM (can cause lags) |
⚠️ Attention: Don't set the animation value off right away. The sudden disappearance of visual effects can be disorienting and create a twitchy interface — 0.5x.
Important warnings and data security
While in the developer section, it is easy to accidentally change a setting that will disrupt the stability of the system. For example, enabling the Touch Show feature can be useful for creating screencasts, but in everyday use it will be annoying to constantly display the touch points on the screen.
Special attention should be paid to the item "OEM Unlocking" (OEM Unlocking). Enabling this option allows you to unlock the bootloader. If you do not plan to install custom firmware or get root rights, it is better to keep this option off. Enabling the unlock bootloader on modern Xiaomi devices often leads to a loss of warranty and inability to use banking applications due to a violation of the integrity of the security system.
What is "hardware acceleration of the GPU"?
If you notice strange behavior of the phone after changes, you can always go back to the developer menu and click Reset button at the top of the screen.This will return all settings to factory values, but will not delete your personal data, photos or contacts.
💡
The rule is, if you're not sure what a particular parameter is in the developer menu, don't change it. The standard MIUI settings are already optimized for most use cases.
