Xiaomi’s current smartphones, including its Redmi and POCO sub-brands, are built on the Android operating system, which by default pulls a lot of advanced tools away from the average user. These hidden sections are primarily for engineers and testers, but they give experienced gadget owners access to fine-tuning the interface, energy management and debugging applications. The standard settings menu offers only basic options, while the advanced functionality allows you to delve deeper into the architecture of the device.
Activating this hidden partition doesn't require root rights or complex bootloader manipulations. The whole process takes literally a few seconds to do a certain action in the About menu. Once enabled, you'll have access to dozens of settings that can speed up the system, change notification behavior, or allow applications to be installed from unknown sources without further confirmation. It's important to understand that changing some values can affect stability, so settings should be approached consciously.
In this guide, we will analyze in detail the algorithm for activating the engineering menu on the shell. MIUI We'll look at the basic parameters that are useful to change immediately after opening access, and answer the frequently asked questions related to the security and functionality of these tools. USB-debugging for communication with the computer and what animations should be accelerated for visually improving the performance of the smartphone.
What is the need for a hidden menu of the developer
The main purpose of this section is to provide tools for testing applications and diagnosing the system during software development, but for the end user, there are some useful features that allow you to customize the experience of interacting with a smartphone, for example, you can force the screen refresh rate, turn on the display of frames per second (FPS) or adjust the behavior of the system at low battery charge.
One of the most sought-after features is managing the scale and speed of animations. MIUI They may seem tight, which creates the illusion of slow operation of the device, and by changing the animation ratios, you can make the interface more responsive and lively. In addition, there are available settings related to debugging, which allow you to transfer data from phone to computer for deep log analysis or device control via ADB-team.
Also in this section is the “Do Not Break Up” feature, which prevents the screen from going to sleep while charging, which is extremely convenient when using a smartphone as a navigator or dashboard. Another important option is to choose a dummy location, which allows you to test geo-dependent applications or hide real coordinates in certain services.
Step-by-step activation instructions for MIUI and HyperOS
The process of enabling hidden features on Xiaomi smartphones is unified and almost the same on different versions of firmware. The algorithm of actions is simple, but requires careful attention when counting clicks. First of all, you need to open the main menu of settings of the device. Usually the icon is a gear and is located on the desktop or in the notification curtain.
In the list of options that opens, you can find the "About Phone" item, which can be at the top of the list or hidden in the "My Devices" subsection, depending on the version of the shell, and it can be all the technical information about the model, Android version and build number. We'll need the line "Version" MIUI» (or "Version" OS» new models).
☑️ Activation algorithm
Find the string with the firmware version number and start quickly pressing it with your finger. 3-4 When you click, you will see a pop-up notification warning you how many times you have to press. Continue to tap rhythmically until the message "You're a developer!" appears. If the system requests you to enter the unlock password of the screen or PIN-code SIM-maps, confirm action.
⚠️ Attention: If after 10-15 If you click on nothing, you may have Child Protection enabled in your security settings, which blocks system settings from changing, and make sure you click on the version number instead of the system logo.
Once activated successfully, a new option, Advanced Settings or Developer-friendly, will appear in the main settings menu, usually at the bottom of the list or in the “Advanced Settings” section, and no further confirmation is required, but the system may request the unlock password again for security reasons when it first starts.
Basic settings for optimizing the system
Once inside the menu, you can encounter a huge number of parameters whose names say nothing without a technical background. You should not change everything. First of all, you should pay attention to the section "Drawing", which is the parameters of scaling windows, transition and animation duration. The standard value is usually 1x.
Changing the animation value to 0.5x visually speeds up the interface, windows open faster, menus respond instantly, but setting a value to 0x (disable animation) can make the interface twitchy and less pleasant to perceive, depriving it of smoothness.
Another useful setup is to activate forced full-screen mode for older applications. Many programs designed before modern cutout screens can be displayed with black stripes. Turning on this option forces the system to stretch the image over the entire display area, ignoring the cutouts under the camera.
| Parameter | Recommended value | The effect |
|---|---|---|
| The scale of window animation | 0.5x | Accelerating the opening of applications |
| Scale of transition animation | 0.5x | Quick switching between screens |
| Duration of animation | 0.5x | Reduced effect time |
| Background limit of processes | No restrictions. | Applications are not unloaded from memory |
| Inactive applications | Disconnected. | Prevents the stopping of background tasks |
💡
If the interface is unstable after changing the animation settings, simply return the zoom values to 1x or reset the developer menu settings at the bottom of the list.
Also worth mentioning is the "Background Limit Process" option: By default, the system manages the number of applications running in the background, but sometimes it does it too aggressively, closing messengers or navigators. Setting a "No Limits" value can solve the problem with missing notifications, although it will slightly increase battery consumption.
Configuring USB-debugging and interaction with PC
One of the key features for advanced users is USB-This tool allows the computer to have full access to control of the smartphone through the protocol. ADB (This is necessary to install applications without Google Play, remove full system logs, unlock the bootloader or restore access to the device if it stopped responding to touches.
To activate, find the item "Debugging by" in the list USB» And you put the switch in the active position, and the system will issue a warning about potential security risks, because this mode gives broad rights to whoever connects the cable to the phone. Confirm the action by pressing OK. When you first connect to a new computer on the screen of the smartphone will be a request for confirmation of the fingerprint RSA-key.
adb devices
adb shell wm density 360In the same section, you can set your default USB mode settings, so that when you connect to your PC, it always offers file transfer, charging only, or MIDI mode, so you don't have to choose the mode in the notification curtain every time you connect to it.
⚠️ Warning: Never leave it on. USB-debugging if you use public charging stations at airports or cafes, and attackers can access your data via the charging port if the debugging mode is active.
You can also activate Wi-Fi debugging, which allows you to wire the device to the computer without having to be on the same network, and it's convenient for wirelessly transferring large files or displaying a screen, but it can consume more power.
Hidden capabilities and experimental functions
There are features hidden deep in the developer menu that can dramatically change how the system behaves, such as the "Show Touch" option that displays a white dot on the screen at the point of touching a finger, which is useful for creating screencasts or teaching older people to see where they're clicking.
An interesting feature is “Enable 5G profile” (if available for your model), which allows you to force the modem to the maximum speed mode, ignoring standard energy saving algorithms, but it is worth remembering that constant 5G operation drains the battery much faster.
What is hardware acceleration of the GPU?
You can also find color space settings here, and if the colors on the screen seem too pale or oversaturated, there are sometimes color mode switches on the developer menu that duplicate or extend the standard screen calibration.
An important option for gamers can be a “GPU Driver” where you can choose a system driver or an updated one received through Google Play, which allows you to update graphics components without waiting for an update of all firmware from the manufacturer, which sometimes solves compatibility problems in new games.
Possible problems and ways to solve them
Despite the security of the procedure, users may encounter unforeseen behavior, and the most common problem is the spontaneous shutdown of the developer menu after rebooting. This is not a bug, but a feature of MIUI protection. After each complete shutdown and turn on the phone, the system must be activated again, unless you have changed the corresponding settings in the hidden configuration files.
Sometimes, after you turn on certain parameters, the phone can start to heat up or discharge faster, this happens if you activate the background processes that the system usually "sleeps down", in which case you just reset the developer's settings to the factory, using the button at the bottom of the menu.
💡
The developer menu is a powerful tool, but it's not designed to continually change all the parameters. Only include the one you're sure of.
If you can't find About Phone or the clicks don't work, check if Guest mode or guest profile is enabled. In a restricted profile, access to system settings is often blocked. Switch to the main account of the device owner.
Security and Return to Original Settings
There are risks with advanced settings, and changing the settings associated with the network or Bluetooth can lead to loss of connection with accessories, so it is recommended to remember the original values or take a screenshot before making a massive change.
To turn off all changes and hide the menu back, you don't have to search for each switch separately. There's a common switch at the top of the developer's settings screen. You turn it off, you deactivate all the functions, but the menu itself will remain visible in the settings list.
To completely disappear the "Developers" item from the settings menu, you need to find the "Reset" button (usually at the top or bottom of the list) and confirm the action. After that, the section will disappear from the interface, and all parameters will return to factory values, as if you never turned it on.
⚠️ Warning: Avoid experimenting with Modem Network or Network Selection options if you don't understand what they're responsible for. Incorrect settings can cause the phone to stop seeing SIM-map or catch a signal, requiring resetting all network settings.
Remember, resetting a developer's settings doesn't delete your personal data, photos, or contacts; it just returns the technical settings to the "out of the box" state. It's a safe operation that can be done as many times as you want.
