Owners of Xiaomi and Redmi smartphones often face the need to find a specific setting that can be hidden deep inside the proprietary shell of MIUI or the new HyperOS. The interface of these devices is significantly different from standard Android, which raises questions among users who move from other brands or update the gadget to the latest version.
In this article, we’ll look at where Xiaomi Redmi’s key management, hidden service codes, and firmware files reside. You’ll learn to navigate the intricate settings structure, find ways to speed up your device, and access features that are hidden by default from the average user.
Understanding the file system structure and settings menu is not only important for advanced users, but also for those who want to manage memory efficiently or adjust notifications. We'll look at both the software aspects and the physical design features of some models. Let's start by looking at your device in detail.
Search for system settings and device parameters
The primary control center for any Android smartphone with a MIUI shell is in the Settings app. However, unlike pure Android, the items here are often regrouped or renamed. To find basic information about the model, processor and OS version, you need to go to Settings → About phone. This is where the build number and the Android version are displayed.
Many users are looking for where the memory management is located in the Xiaomi Redmi phone. In newer versions of the firmware, this section has been moved. Now, to clean the cache and manage the storage, you should use the built-in Security app, which has a lightning shield icon, and inside it is the Cleanup item, which analyzes the space and suggests removing debris.
If you are interested in an extended settings menu that includes developer options, there is no standard switch in the interface. You need to activate it manually. To do this, go to the About Phone section and quickly click 7 times in a row on the MIUI version or OS version. After that, a new section will appear in the main settings menu, Advanced Settings.
Importantly, some features may vary depending on the regional firmware version (Global, China, EEA). In Chinese versions, some system applications may be called differently or not. Global users may be able to use the interface, but the deep folder structure remains the same for the ecosystem.
Access to engineering menus and hidden functions
For a deeper diagnosis of hardware components in Xiaomi phones, there is an engineering menu, a hidden part of the system designed to test communication modules, speakers, screens and sensors in production, and you can access it through a standard "bell ringer" by dialing a special device. USSD-code.
The most common code to log into the engineering menu is ##6484##. Once you enter the last character, the menu will open automatically, without having to press the call button, and here you can check the vibrator, the color calibration of the display, and the status of the proximity sensors.
⚠️ Warning: Be extremely careful when changing parameters in the engineering menu.Resetting the screen calibration or changing the modem frequency ranges without understanding the process can lead to malfunction of the device.
Another useful hidden code is ##4636##. It opens the testing menu, where you can see detailed battery usage statistics, Wi-Fi connection information and cellular network settings, and you can force the phone to LTE Only or 3G Only mode, which is useful in areas of signal instability.
Some users are looking for where the Xiaomi Redmi phone has logs, which can also be accessed through the USB debugging included in the developer menu, but it is safer for the average user to use the built-in logger tools in the Services and Feedback app if installed in your firmware version.

Location of system files and folders in memory
When connecting a smartphone to a computer through USB-cable (MTP), And the user sees the root directory of internal memory, and there are folders of application data, for example, DCIM For photo, download for download and MIUI for system recordings of voice recorders or screenshots.
However, system files such as firmware files, libraries, and OS configurations are in a secure root partition, which is closed without superuser permission (Root), and if you try to find /system or /data folder through a standard Explorer, you simply won’t see them.
Managing hidden files requires obtaining Root rights, such as through Magisk, and using specialized file managers, such as Root Explorer or MT Manager. Without these tools, the operating system blocks access to critical partitions to avoid damaging the bootloader.
| folder | Location. | Description of the contents | Access. |
|---|---|---|---|
| DCIM | Internal memory. | Camera photos and videos | Complete. |
| Android/data | Internal memory. | Cash and application data | Limited (Android 11+) |
| MIUI/gallery | Internal memory. | Drafts and cloud albums | Complete. |
| /system | Root section | Operating system files | Only the Root. |
And I'm going to mention the Android/obb folder, which stores heavy game files, and if you're looking for where the cache data of cards or heavy apps is stored in the Xiaomi Redmi phone, this is where you go, and cleaning up that folder will make you need to re-download the app resources.
💡
When connecting to a PC, select File Transfer (MTP) mode rather than Charge only, otherwise the computer won’t see the data folder.
Application and Autoboot Management
One of the most common challenges is finding autoload settings. MIUI has a separate app launch control mechanism that is different from standard Android. You can find it through the app Security → Permissions → Autorun.
This shows you a list of programs that start with the phone, and turning off unnecessary services helps save battery power and RAM, but system processes are best left unchecked, as this can disrupt notifications or synchronization.
It is also important to set the applications in the background. To do this, go to Settings → Applications → All applications, select the right one and press the Battery. Select No Limits mode if you want the messenger or navigator to work constantly, even if the system tries to “sleep” the device to save energy.
- 📱 Task Manager: Call the menu of running apps and click on the lock next to the important process to prevent it from being unloaded from memory.
- 🔋 Power Saving: Turn on Ultra Battery Saver only in emergency cases, as it blocks most background services.
- 🔔 Notifications: Configure the display of notifications is in a separate menu item of each application in the section "Notifications».
Users often ask where to find remote apps. Xiaomi has a shopping cart, but it only works for standard system applications and is located in the Security app → Delete Apps. Third-party programs are removed without the possibility of recovery through the Recycle Bin.
Configure notifications and notification line
Xiaomi’s notification curtain interface has undergone significant changes in the latest versions of MIUI. To change the display style (classic or new), go to Settings → Notifications and Status bar → Notification style. Here you can choose how messages from different applications will be grouped.
Special attention should be paid to the “Floating Window” feature, which allows you to open applications in a small window on top of others, and you can activate it by swiping up from the bottom of the screen in the multitasking menu or through the sidebar.
⚠️ Warning: Turning on Do Not Disturb Mode hides not only the sound, but also the visual display of notifications on the locked screen unless exceptions are configured for selected contacts.
If you’re looking for where the Xiaomi Redmi phone is configured with an LED light (if it’s in the model) or screen lighting effects, the path is: Settings → Additional → Lighting. In models without LED, this feature is replaced with “Affects at Notifications” that use screen backlighting.
