Xiaomi and Redmi smartphone owners often face a situation where familiar controls change their location or disappear after a system update. The MIUI shell or the new HyperOS offers many layers of interface that are easy for a beginner to get confused. Finding the main settings menu is the first step to fully use all the features of your device.
In this article, we will take a look at all the ways you access system settings, including those hidden by default. You will learn how to find the engineering menu for diagnostics, where advanced display settings are hidden, and why the standard settings button may disappear. In modern versions of MIUI, access to some system logs is limited by developer rights.
Understanding the navigation structure is not only essential for basic setup, but also for battery optimization, memory management, and increased security. Let’s look at the basic methods of accessing your smartphone’s brain.
Basic ways to open the main menu settings
The most obvious and frequently used method is to search for the Settings icon on your desktop, which looks like a gray or white gear on the standard MIUI theme, and if you can't see it on the home screen, swipe your finger up the center of the screen to open the list of all apps installed (App Drawer), and find the right shortcut there.
An alternative and faster way to call the menu is to use the built-in search bar. Swipe down the center of the screen to activate a global search, and type in the word "Settings" or "Menu." The system will prompt you to launch the corresponding application instantly, which is especially convenient if you have a lot of programs installed and you don't want to waste time on visual search.
You can also call settings through the control panel. Swipe down from the top right corner of the screen (or from the top left, depending on the control style you choose) to open the "curtain." At the top of the notification panel, there is usually a button with the image of a gear that leads directly to the System settings section.
For users who prefer voice control, it is possible to run through the assistant. Simply say the command "Open Settings" or "Settings" if you have Google Assistant or Xiao AI activated. This allows you to control the phone without touching the screen, which can be critical in certain situations.
Navigation in the engineering menu and hidden sections
To get a deeper diagnosis of the device, there's a so-called engineering menu, which is a hidden section that's designed to test hardware components, check signals and calibrate sensors, and you can access it through the standard Phone app by dialing in a special one. USSD-code.
Type ##6484## on the dial keyboard. If your operator and firmware support this feature, the CIT (Customer Information Test) interface will open, where you can check the vibration, screen, microphone and communication modules. Be careful: changing the parameters in this menu without understanding the consequences can lead to malfunction of the device.
- 🔍 Checking the display: test for broken pixels and sensitivity of the touch screen.
- 📡 Communications Diagnostics: Signal Level Check GSM, Wi-Fi and Bluetooth modules.
- 🔋 Battery information: viewing the real battery wear and charging cycles.
- 🎤 Audio test: check the main and additional microphones.
⚠️ Warning: Do not change the values in the engineering menu if you are not sure of your actions.Resetting the sensor calibration or changing the frequency of the processor may require reflashing the device to restore operability.
Another hidden section is Advanced Settings for developers, and to activate it, you need to go to About Phone and click on MIUI 7 times quickly. After that, a new option will appear in the main settings menu, For developers, where you can adjust the animation speed, debugging over USB and the limit of background processes.
What to do if the engineering menu code doesn’t work?
Managing MIUI and HyperOS interface elements
Xiaomi shells are famous for their flexibility, but sometimes it leads to the user being lost in the abundance of options. If you are looking for where to find the menu for managing specific functions, it is most likely hidden in sub-items. For example, vibration and sound management is not only in the section “Sound”, but also duplicated in “Tactile Impact”.
In the new versions of HyperOS, the menu structure has been redesigned for more consistency. Key switches are now displayed in widgets on the desktop or in the control center. If you have recently updated and can not find a familiar item, search inside the settings themselves: click on the magnifier at the top of the Settings screen and enter the name of the function.
☑️ Checking interface settings
Often users search for the application management menu, which is located on the Settings → Applications → All applications, where you can delete system programs (if you have rights), clear data or limit background activity, which is an important section for optimizing performance.
| Settings section | The way is on the menu | Substantive function |
|---|---|---|
| Screen. | Settings → Screen and brightness | Hertz frequency, reading mode |
| Notifications | Settings → Notifications and Status Bar | LED indicator, pop-up windows |
| Battery | Settings → Battery | Energy saving, expenditure statistics |
| Passwords. | Settings → Passwords and security | Fingerprint scanner, face unlock |
Remember that the menu may look different depending on the theme you choose. If the standard interface seems uncomfortable, visit the Themes app and select a design with a different icon structure and menu.
Solving problems with the disappearance of the settings menu
Sometimes, the Settings icon disappears from the desktop or stops opening, which can be caused by a system launcher malfunction or an error after a failed update. First of all, try restarting the device, and 80 percent of the time, it puts everything back into place.
If the reboot didn't work, check if the app is hidden. There's an app hide feature in MIUI. Go to the Security app, scroll down to Hidden Apps and check if it's ticked against Settings. If it's, remove it.
⚠️ Note: If the settings menu does not open and crashes immediately after launch, system files may be damaged, in which case it is recommended to reset to factory settings, saving important data in the cloud beforehand.
The problem may also be in a crowded system interface cache. Go to Apps → All Apps, search in the Settings list, and click Clear → Clear Cache. This action is secure and won’t delete your personal data, but can fix the startup error.
💡
If the settings menu opens but is slow, try turning off animations in the developer section → window animation scale → no animation.
Set up a special menu for people with disabilities
Xiaomi and Redmi have a powerful set of accessibility features, a special feature menu that lets you control your phone with a single touch, voice commands or external switches, and you can find these settings by going to Settings → Advanced Settings → Special features.
This activates a Special Opportunity Menu, which adds a floating button to the screen or uses a combination of volume keys to call for quick action, which is useful not only for people with disabilities, but also for quick access to screenshots, screen zoom or focus control.
- 👁️ Screen announcer: voice action for the visually impaired.
- 🖐️ Gesture management: tweaking the back panel.
- 🎨 Color correction: regimes for color blind.
- 🔊 Sound amplification: mono-audio and channel balance.
Activating these features can slightly increase battery consumption, as they constantly monitor user activity, but for those who need constant interface support, it is an indispensable tool. All changes are instant and do not require rebooting.
Optimizing the Quick Access Menu and Control Panel
The Control Center in MIUI is separated from the notification curtain, which is a signature feature of the interface. To set it up, go to Settings → Notifications and Status Bar → Control Center. You can change style (classic or new), add or remove switches.
Click on the edit button (usually at the bottom of the switch list) to add frequently used features such as Read Mode, Translation, or Screen Write.This will allow you to find the desired menus in one click without wandering through deep settings.
💡
Competent setting of the quick access panel saves up to 30% of time with daily use of the smartphone, eliminating the need to search for functions in the depth of the menu.
You can also customize the behavior of indicators in this section, such as enabling real-time Internet speed displays or changing the time format, which makes using a Redmi smartphone more comfortable and personalized.
