Modern smartphones running MIUI or HyperOS shells offer users a huge amount of customization, but a significant portion of these tools are hidden from the eyes of the average owner. The standard settings menu offers only basic personalization options, while deeper system management requires access to a special engineering section, which is where interface speed controls, application debugging options and hidden Bluetooth settings can significantly improve the user experience.
Many users are wondering why you should activate a hidden menu at all, if the phone is already stable. The answer lies in the desire to optimize the device for your specific tasks, whether it is speeding up the response of the screen or connecting specialized gadgets via USB. The developer’s functions are not just a toy for geeks, but a necessary tool for those who want to squeeze out their Xiaomi or Redmi maximum performance and functionality without installing third-party firmware.
The activation process does not require root rights or complex software, but it requires careful and accurate sequence of actions. Error when changing critical parameters in this section can lead to unstable operation of the operating system, so it is important to understand what each option is responsible for before making changes to the standard configuration.
What is the developer menu and why it is needed
The developer menu is the Android system partition that is hidden by default to prevent inexperienced users from accidentally changing settings. In Xiaomi devices, this section contains dozens of parameters that affect the operation of the processor, graphics accelerator, network modules and debugging systems. By activating this mode, you get access to tools that are usually used by programmers in testing applications, but which are useful in everyday use.
One of the most sought-after features is to scale up the animation of the interface. Standard values often seem redundant, giving the illusion of a smartphone being slow. By adjusting these parameters, you can make the transitions between the screens instantaneous, which subjectively improves the performance of the device. And there are settings that prevent the system from killing background processes, which is critical for messengers and navigators.
⚠️ Attention: Changes in parameters related to the smallest width (DPI), It can cause the interface to become unreadable or some controls to disappear outside the screen.
Another important function is the ability to force hardware acceleration on. GPU for 2D-This can solve rendering problems in older apps or games that aren't optimized for today's high-resolution screens. Also, you can find information about the processor’s running time and real-time memory usage, which helps diagnose the causes of sudden battery discharges.

Step-by-step instructions for activating the hidden menu
The process of turning on the developer mode on Xiaomi, Redmi and POCO smartphones is unified and takes no more than a minute. You do not need additional applications or a connection to the computer, all actions are performed directly in the operating system interface. The main thing is to follow the algorithm precisely, since the number of taps on the screen is strictly regulated by the MIUI security system.
To start, open the standard Settings app and scroll down to the bottom. You're interested in the About Phone (or My Phone), which is usually at the top of the list or at the bottom, depending on the shell version. Inside this section, you'll find the MIUI version or OS version line. This is the line where you need to apply a series of quick fingerstrokes.
Make 7-10 quick taps on the field with the firmware version. A counter will appear on the screen to tell you how many times you have to press before activating the mode. When the counter disappears, you will see a pop-up notification “You became a developer!”. After that, a new “Developers” option will appear in the main settings menu, in the “Additional” section.
☑️ Activation algorithm
If the menu does not appear after you have completed all the actions, check if the device has a password for entering the settings or parental control restrictions that can block changes in system settings. In rare cases, some global firmware versions require prior authorization in the Mi Account account, which the system will inform you accordingly.
Setting the speed of animation and interface
One of the first things that users change after activating developer mode is animation scale. Android and MIUI have 1x coefficients installed by default, which means standard transition times. Reducing this value to 0.5x or even completely disabling (0x) makes the interface noticeably more responsive and lively, eliminating visual delays between touch and system response.
To find these options, go to the Developer Menu and scroll to the Drawing section, where you will find three key parameters: “Scale of window animation,” “Scale of transition animations,” and “Scale of animator duration.” It is recommended that all three values be changed synchronously to maintain visual consistency of the interface.
- 🚀 The scale of window animation – regulates the speed of opening and closing applications.
- 🔄 Transition animation scale – responsible for the speed of switching between desktops and menus.
- ⏱️ The scale of the animator duration – affects the duration of internal processes within applications.
It is worth noting that completely disabling animations (value 0x) can make the interface too sharp and twitchy, which not all users are comfortable with.The optimal balance between speed and smoothness is considered by many to be 0.5x, which retains the feeling of quality software, but significantly reduces latency.
💡
If the animation scale changes, the interface becomes unstable, or the applications start to crash, just put the scale back to 1x. This won't hurt the data, but it will restore the standard behavior of the system.
Management of background processes and memory
Android is known for its aggressive memory management policy, which on Xiaomi devices with MIUI shells is often reinforced by additional limitations to save battery life.This leads to the fact that navigators, music players or instant messengers can unexpectedly close in the background.
The Applications section contains the "Background Process Limit" option, which is set to the "Standard Limit" default, but the user can choose "No Background Processes" to maximize energy savings or specify a specific number of processes left behind.
Activating the “Do Not Activity” function causes the system to destroy the application process as soon as the user leaves its screen.This is useful for testing, but in everyday use will lead to a constant reboot of applications with each switch, which will increase battery consumption and CPU load.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Process limit | Standard constraint | Balance between multitasking and RAM |
| Background mode | Included (for important) | Prevents the Navigator from closing |
| Activity | Off. | Maintains the state of applications |
For critical applications such as Yandex.Navigator or corporate messengers, it is better to use not global settings of the developer menu, but individual permissions in the Battery and Performance section, which will save the background work of the desired programs without loading RAM with unnecessary processes.
Debugging over USB and interaction with PC
Function “Debugging by” USB» It's the cornerstone of how a smartphone interacts with a computer at a deep level, and it allows you to send commands through a protocol. ADB (Android Debug Bridge, install apps directly from the IDE, You can do full backups and access logs in real time. Without this option, most advanced Android management tools are not available.
When the first connection of the smartphone with debugging enabled to the new computer, a confirmation request will appear on the device screen RSA-This is a security measure that prevents unauthorized access to phone data from someone else's PC, and you have to click "Allow" and, if you want, tick "Always Allow from this computer" so you don't confirm the connection every time.
⚠️ Warning: Never leave the debugging mode on USB If you use public charging stations frequently, attackers can use this port to steal data or install malware while the phone is charging.
Also available in this section is the option "Select configuration mode". USB And here you can set the behavior of the phone when you connect the cable: will it just charge, will it work as a storage device (MTP), picture (PTP) or MIDI-For normal file transfer, the most universal mode is MTP.
Network settings and Bluetooth
The network settings section of the developer menu offers tools to diagnose and improve connectivity, for example, the “Always turn on mobile internet when Wi-Fi is connected” feature can be useful in situations where the wireless network has limited access to the global internet, but you don’t want to turn off Wi-Fi completely.
For wireless headphone and wearable users, Bluetooth settings are interesting. In the developer menu, you can find codec options such as LDAC, aptX HD or SBC. Forced choice of quality codec can improve sound, but only if your headphones also support this audio data transfer standard.
- 📶 Wi-Fi aggregation – combining 2.4 GHz and 5 GHz bands to increase speed (requires router support).
- 🔍 Bluetooth log – maintaining a detailed log of all Bluetooth events to debug connection problems.
- 🌐 Mobile Access Point – Range setting AP for Wi-Fi distribution (2.4 GHz or 5 GHz).
Be careful with the setting “Use”. IPv6» alteration DNS-Incorrect network settings can lead to loss of Internet access even if there is an active signal of the cellular network.
💡
Changing the Bluetooth codec in the developer menu will only give a tangible result if you have compatible headphones; otherwise, the system will automatically return to the standard SBC codec.
Additional tools and monitoring
In addition to basic settings, the developer menu includes a number of diagnostic tools, such as the “Tap Display” feature, which visualizes every touch of the screen in a white circle, which is extremely useful for checking the touchscreen, especially if you suspect the presence of “dead zones” or ghost touches.
Another interesting option is "Show CPU load," which, when activated, will show a graph at the top of the screen showing the current load of the CPU cores in real time, which allows you to visually assess how heavy the application or game is on the system, and whether it causes the device to overheat.
For gamers available option "Driver Mode" GPU». You can choose to use a standard system driver or a driver from the Play Market (if it is updated independently of the system). Switching can help in running emulators or games that require more recent graphics libraries than those sewn into the firmware by Xiaomi.
