Many Xiaomi, Redmi and POCO smartphone users often wonder what Quick Xiaomi is and where to find these features to improve performance. The term usually refers to a set of quick settings, hidden engineering test menus and specialized modes of operation that allow instant changes in device settings without going deep into standard menus. Understanding these mechanisms opens up access to advanced control of the gadget, allowing you to customize the behavior of the touch screen, network and notification system in one click.
In the MIUI ecosystem and the new HyperOS, the concept of Quick permeates the entire operating system structure, from the control center to specialized memory cleaning applications. However, what not everyone knows is that behind standard brightness sliders, powerful debugging tools are hidden that can solve problems with freezes or poor signal reception. By understanding how the engineering menu is activated through the code ##6484#, you get access to diagnostics that are not available to the average user.
Next, we’ll take a closer look at what features are behind this concept, how to use them safely, and what hidden features your phone has, and we’ll look at not only the software settings, but also the physical features of quickly launching apps, and optimizations that actually work, not myths from the Internet.
What is hidden under the term Quick Xiaomi
The term “Quick Xiaomi” is not the official name of one particular app that can be found on Google Play. Rather, it is a collective concept that combines several system components designed to instantly access functions. First of all, we are talking about Quick Settings, which are in the notification curtain. This is where the user can add widgets to turn on a flashlight, Bluetooth, flight mode or access point without having to open the full system settings.
The second aspect is Quick Ball, the iOS analogue of Assistive Touch, which came in the MIUI shell. This floating element on the screen allows you to run apps, take screenshots or lock the screen with a single touch. For many large-diagonal phablet owners, this is a salvation, as reaching the top corner of the screen with one hand becomes physically difficult. Activating this element significantly changes the ergonomics of using the device.
The third component that's often searched for under this query is hidden engineering menus and debugging modes, which allow you to switch network modes (like 4G only), test the sensor or calibrate the display. These tools are designed for service centers, but also available to advanced users who want to fine-tune their gadget. It's important to understand that changing the settings in these menus can affect the stability of work, so you need to experiment with caution.
Quick Ball and One-Hand Control
Quick Ball is a customizable floating button that can act as a shortcut for frequently used actions. Once activated, a translucent sphere appears on the screen, moving which does not interfere with the main content. When you click briefly, it deploys a menu that can be placed up to five shortcuts: start the camera, lock the screen, screenshot, clear memory or open a specific application.
Customizing the behavior of the ball allows you to set the reaction to a long press or double touch. For example, double pressing can start the voice recorder, and long press can take a screenshot. This is especially convenient for people who often take screenshots at work or school. In the HyperOS shell, Quick Ball animations have become smoother, and the button itself has learned to adapt better to the dark theme of the interface.
⚠️ Note: Do not place Quick Ball in the corner of the screen if you have the wrist lift function or other unlock gestures enabled, as this can cause accidental triggers when removing the phone from your pocket.
To activate this feature, you need to follow the Settings → Additional Features → Quick Ball. You can choose the size of the button, the degree of transparency and the tool set. You can also use the option to hide the ball when you start games or video players so that it does not overlap the view, which makes the tool a versatile and unobtrusive assistant in everyday use of a smartphone.
💡
Use Quick Ball to quickly access a calculator or voice recorder during calls so you don’t interrupt the conversation and record important information right away.
Quick settings and customization of curtains
The Control Center or Quick Curtain is the first interface that a user interacts with after unlocking. In modern versions of MIUI and HyperOS, this section was divided into two parts: notifications on the left and switches on the right (in the classic style) or combined into a single panel (in the style of iOS).
To edit a set of buttons, you have to pull the curtain down and click on a pencil icon or three dots in the corner, and you have useful tools like Read Mode, Screen Record, Security and Screenshot available here, and the Security button allows you to instantly run a deep cleaning or virus check, which is useful when you install applications from unknown sources, and this is an important aspect of mobile security.
It is important to note that some hidden switches can only be activated through special applications or ADB-But a standard set is usually enough for 95 percent of users, like the Access Point button, which allows you to instantly distribute the Internet without going into the deep settings menus of the network. The correct configuration of this space saves seconds each time you need to change the connection setting.
- 📱 Screen recording: allows you to record what is happening on the display with sound, which is convenient for creating instructions.
- 🔋 Energy saving mode: instantly limits background processes to extend battery life.
- 📶 Mobile Internet: Quick access to settings APN network selection 4G/5G.
- 🔦 Flashlight: includes flash even from a locked screen (if the appropriate settings).
☑️ Setting up the perfect curtain
Engineering menu and codes for diagnostics
When you talk about Quick Xiaomi in the context of advanced customization, you often mean access to the CIT (Customer Integration Test) menu, which is a hidden section of the system designed for factory testing of components, and is logged in through a set of special code in the Phone app. The most famous code is ##6484##, which opens a complete engineering menu with dozens of tests.
This menu can check the vibrator, microphone, speaker, sensor, GPS and accelerometer. If you have a proximity sensor that stops working (the screen doesn't go out during a conversation), this is where you can start calibrating it. It doesn't require root rights and is safe if you just run tests instead of changing system files. However, be careful with items labeled "Write" or "Set."
Another useful code is ##4636##. It opens up a menu of phone information where you can force the network to switch mode. For example, if the phone is constantly "jumping" between 3G and 4G, you can select "LTE Only" mode here. This stabilizes the connection in areas of insecure reception, but remember that incoming calls may not pass in "LTE Only" mode unless VoLTE technology is configured.
| Code. | Function | Security |
|---|---|---|
| ##6484## | Complete Iron Testing (CIT) | Safe (tests only) |
| ##4636## | Telephone and network information | Safe (careful with the network) |
| *#06# | IMEI display | Completely safe. |
| ##7780## | Resetting (Factory Reset) | ⚠️ Dangerous (deletes data) |
⚠️ Warning: Never change the values in the Radio Information section (code 4636) unless you understand what a particular parameter is responsible for.
What if the code doesn't work?
Optimizing Performance and Quick Start
MIUI Optimization and the new HyperOS algorithms include features often referred to as Quick Start, or fast boot, a mechanism where frequently used applications are not closed completely, but frozen in RAM, allowing them to open almost instantly, but on devices with low RAM (4GB or less), the system can aggressively unload processes, which negates this effect.
To manage this process, you have an Advanced Cleanup menu and set the applications in the background. In Settings → Applications → Application Management, you can select a specific program and prevent the system from closing it. This is useful for messengers to make notifications come instantly, or for navigators who need to work in the background.
Also worth mentioning is Game Turbo, a software layer that redistributes CPU resources when a game is launched, prioritizing gameplay, and blocking distracting notifications, which allows you to take screenshots, record videos, and even change sensor settings for faster response, and is a must-have tool for gamers that is often underrated.
- 🚀 Auto-Run: Managing programs that start with the system.
- ❄️ Freeze: Temporary stop of heavy applications without removal.
- ⚡ Game Turbo: Allocating resources CPU/GPU play-off.
- 🧹 Memory Cleansing: Freeing RAM before starting a heavy task.
It's important to understand that the Play Market accelerators often perform worse than Xiaomi's built-in tools, they consume resources by hanging in the background. The built-in MIUI optimization engine knows the features of iron better than any third-party utilities, so it's enough to set up the built-in tools correctly to maintain speed, rather than install additional software.
💡
The built-in MIUI and HyperOS optimization tools work more efficiently than third-party “accelerators”, since they have access to the processor resources management at the core level of the system.
