Xiaomi and Redmi smartphone owners often face the challenge of accessing hidden Android operating system features. The standard MIUI or HyperOS shell interface hides a host of tools designed to test hardware and fine-tuning applications. This is where special engineering menus come to the rescue.
Access to these settings not only speeds up the interface, but also connects the smartphone to the computer for deep diagnostics. Without activation of this mode, many advanced functions remain inaccessible to the average user. In this article, we will discuss all the nuances of activation and safe use.
Enabling hidden options is the first step to full control of the device, but it is worth noting that carelessly changing system variables can lead to unstable operation of the gadget, so before any manipulations, it is important to clearly understand what each function is responsible for.
Why You Need to Access a Developer Mode
The main purpose of this section is to provide tools for app creators and test engineers, but ordinary users can find useful customization options here, for example, changing the speed of window animation makes the interface visually more responsive and faster.
USB debugging is a key feature that allows data to be transferred between the PC and the phone at a low level, which is necessary for installing drivers, flashing the device through the computer or using specialized software to manage the file system.
You can also manage background processes here, you can limit the number of applications running or force services to stop that consume too much resources, especially for low-end Redmi models with little RAM.
- 🚀 Speeding up the interface by changing the scale of animation.
- 🔌 Direct PC connection for file transfer and debugging code.
- 🛠 Location and sensor testing.
- ⚙️ Forced closure of background processes to release RAM.
It is important to note that some features may conflict with the operation of standard applications, for example, changing the screen density (DPI) can make some interface elements unreadable, so all changes should be made consciously.
Step-by-step activation instructions for MIUI and HyperOS
The process of enabling hidden menus on Xiaomi smartphones is different from standard Android, which requires not just clicking on the build number, but first activating intermediate status, this is done by the developers of MIUI to additionally protect the system from accidental changes.
First, you open the main settings menu and find the About Phone section, and at the top of the screen you'll see the operating system version, and that's the field you'll click seven times in a row, and then you'll notice that you've become a developer.
☑️ Algorithm for initiation of the regime
Once you activate it successfully, a new item will appear in the main settings menu, at the bottom of the list, which can be called Additional Settings or simply Advanced Settings, and inside this section, the menu you want to find is hidden.
⚠️ Note: On some firmware versions, after seven times pressing, the system will require you to enter the unlock password or the pattern lock.
If the item doesn't appear right away, try restarting the device. Also make sure you have the latest stable version of the shell installed. In beta versions, the menu layout may differ.
Where is the menu after switching on?
After completing all the activation steps, the new partition is integrated into the system structure. Depending on the Android version and the MIUI shell, the path may vary slightly. Most often: Settings → Additional settings → For developers.
The new versions of HyperOS have the same logic, but the visual design may have changed, and the icon is not usually displayed on the desktop, only accessed through the system menu, which prevents unauthorized entry.
If you search by settings, simply type in the phrase “developer” or “debugging” and the system will highlight the desired item, which greatly simplifies navigation in the confusing menu of modern smartphones.
| Shell version | The path to the menu | Features |
|---|---|---|
| MIUI 12 / 13 | Settings → Additional settings | Classical location |
| MIUI 14 | Settings → Additional settings | New debugging functions added |
| HyperOS 1.0 | Settings → Additional settings | Changed interface design |
| Android 13/14 | System settings | Depends on the skin of the manufacturer |
💡
Use search in settings if you can’t find the item manually – this is the fastest way to get to the desired menu on any Xiaomi.
Key features for ordinary users
And among the dozens of technical parameters, there are a few that are really useful in everyday use, most notably the scale of animation, changing from 1.0x to 0.5x makes the transitions between screens instantaneous, creating a sense of high performance.
Also worth paying attention to is the "Don't Turn Off" feature, which, if activated, will keep the display on continuously while charging, which is convenient when the smartphone is used as a desktop clock or dashboard.
Touch Show allows you to visualize the clicking points on the screen, which is useful for creating screencasts or teaching older people how to use a smartphone, because you can see where the tap was made.
- 🎨 The scale of animation – speeds up visual effects.
- 🔋 Do not turn off the screen – convenient when charging.
- 👆 Showing touches - demonstration of actions on the screen.
- 📊 Process statistics – real-time load monitoring.
Don’t touch settings related to network protocols or Bluetooth codecs if you don’t understand their purpose, which can lead to loss of connection to accessories or unstable Internet operation.
Configure debugging over USB and work with ADB
To connect the smartphone to the computer for deep diagnostics, you need to activate the USB Debugging Switch. When you first turn on, the system will issue a security warning. You must agree to allow the computer to access the command line of the device.
Once you connect the cable to your PC, you'll see a request on your smartphone screen for debugging permission from that computer, and you'll be sure to check the RSA keyprint and press "Allow." Without that step, the computer won't see the device in debugging mode.
adb devicesThis command in the computer console will check if the device is connected, and if done correctly, you'll see your Redmi serial number, which gives you access to installing apps bypassing the store, removing system debris, and a full data backup.
What to do if your computer can’t see your phone?
Always turn off this feature when it is not in use.
Optimizing memory and processes
In the developer section, you can find settings that control application background activity, the Background Process Limit option, which allows you to severely limit the number of programs running simultaneously, which can extend battery life on older devices.
However, setting too strict a limit (for example, "No background processes") will lead to the fact that messengers will stop sending notifications, and music will stop when you leave the application. 2-3 processes".
It also has a Do Not Save Action feature, which, if enabled, will destroy the activity of the application as soon as the user leaves it, which is useful for testing, but very inconvenient for everyday use, as the applications will be constantly restarted.
⚠️ Warning: Forced process termination may disrupt system services MIUI, such as gallery synchronization or cloud backup.
Modern versions of Android manage memory effectively themselves, and manual intervention often does more harm than good.
Safety and Return to Factory Settings
The main rule of the engineering menu is not to change the settings, the purpose of which you do not know, reset all parameters to the original state through the button "Reset" at the bottom of the developer menu, which will return all the changed values to the factory.
If you change the DPI and the interface becomes unreadable, don't panic. Remember the original value or just reset the developer settings. The screen will return to normal after the reset or immediately after the reset.
To completely disable the mode, simply turn off the switch at the top of the menu, the "Developers" item will disappear from the settings, and access to hidden functions will be closed, this is a standard deactivation procedure.
💡
Resetting the developer settings is safe for personal data (photos, contacts), it returns only system parameters to the original state.
Check the list of computers that are allowed to debug regularly. There is an option on the menu called "Cancel access to debugging over USB," which deletes all saved RSA keys. Do this when you sell your phone or lose a trusted PC.
