Owners of Xiaomi, Redmi and POCO smartphones often face the need to access hidden features of the Android operating system. The standard MIUI interface hides many tools that allow you to fine-tune the device to yourself, speed up its work or connect the gadget to the computer for deep diagnostics.
By default, this section is hidden from the eyes of the average user to prevent accidental changes in critical parameters that can disrupt the stability of the gadget. However, with the exact sequence of actions, anyone can activate it in seconds. In this article, we will discuss in detail where the developer menu on Xiaomi is, how to activate it and which settings should be changed in the first place to improve the user experience.
The need to access these settings arises for various reasons: someone needs to speed up the animation of the interface, another – to allow the installation of applications from unknown sources or enable debugging to work with ADB. Understanding how to manage these functions, turns your smartphone from a conventional device into a powerful tool with advanced capabilities.
What is a developer mode and why it is needed
The developer menu is a special section in the operating system settings that contains tools for debugging applications and testing software, originally created by engineers and programmers to find errors in the code and check for new features before release, but over time, ordinary users have appreciated the convenience of some options that allow you to customize the operation of the smartphone.
In the context of Xiaomi devices, this section is especially important, as the shell is very important. MIUI (And the new version of HyperOS has a lot of features, so for example, without the flags on this menu, you can't really use the function. USB-debugging, which is required to install custom recavers, unlock the bootloader or control the phone from the computer.
And then there's the settings that affect the visual experience of the interface, and many people don't know that standard animation speeds in Android are artificially slowed down for smoothness, and by changing the scaling ratios, you can make the response almost instantaneous, which is especially true for models with less-performing processors.
⚠️ Warning: Changing the settings in the developer section can cause the system to run in an unstable way. Do not change values that you do not know the purpose of, especially those related to GPU work or background processes.
It's also worth noting that activating this mode doesn't take away the warranty, and it's not a malicious action unless you make destructive changes. It's a regular Android feature, just hidden in the back of the menu. Using the tools available correctly allows you to extend the battery life, optimize the use of RAM and speed up the launch of applications.
Step-by-step instructions for activating the hidden menu
The process of enabling hidden features on Xiaomi smartphones is unified for most models, regardless of which version of the MIUI or HyperOS shell is installed. The whole procedure takes no more than a minute and does not require a connection to the computer or root rights. You only need the smartphone itself and attention when performing tappings.
The first step is to get to the main settings menu. Find the icon on the desktop with the image of the gear or swipe the notification curtain down and click on the settings icon. In the list of options that opens, you need to find the item About Phone. It is usually located at the top of the list or at the bottom, depending on the version of the interface.
☑️ Algorithm of Including Developer Mode
Inside the About Phone section, you'll find detailed information about the model, the processor and the software version. We're interested in the MIUI version string (or the HyperOS version of the OS), which is where you put a series of quick fingerstrokes. You don't have to guess the rhythm, the main thing is to make about 7-10 taps at a fast pace.
When you click, the system will give out pop-up timer notifications, counting how many times you have to press. When the counter reaches zero, the message "You are a developer!" will appear on the screen. After that, a new item for developers will appear in the main settings menu, in the Additional section.
If the system requests a screen unlock password, or PIN-SIM card code, it's a normal Xiaomi security measure. Enter the code and access will be open. Now you can move on to fine-tuning the system, knowing exactly where the developer mode on Xiaomi is.
Setting the speed of animation and interface
One of the most popular reasons users are looking for access to the engineering menu is to speed up the interface. Android's standard settings set the animation ratio to 1x, which creates a smooth effect, but visually slows the transitions between windows. Changing this setting makes the smartphone noticeably "live".
To access these settings, go to Settings → Additional → Developer. In the list that opens, you need to scroll down to the Drawing section, and there you will find three key options:
- 🎨 Windows animation scale – responsible for the speed of opening and closing applications.
- 🔄 Transition animation scale – adjusts the speed of switching between desktops and menus.
- ⏳ Duration of animation – affects the time of displaying transitions in system dialogues.
By default, all these values are set to 1x. Experimentally, it was proved that the optimal value for the balance between smoothness and speed is 0.5x. Setting a value of 0x (disable animation) will make the interface twitchy and less pleasant to perceive, so this option is recommended only on very old devices.
💡
After changing the scale of the animation, restart the smartphone so that the system fully applies the new rendering factors of the interface.
Changing these parameters doesn't affect the performance of the processor, but it subjectively speeds up the device. You no longer have to wait for the window to leave when you fold the application, and this is especially noticeable on models with screens with a refresh rate of 60 Hz, where every millisecond of response matters.
Function USB-debugging and working with ADB
USB debugging is perhaps the most important technical tool in the advanced user’s arsenal, a feature that allows the computer to send commands to a smartphone, access the file system, and manage the device at a deep level. Without debugging enabled, many programs for backing up, transferring data, or installing modified software will not work.
To activate this function, while in the developer menu, find the Debugging Switch USB And you activate it. The system will give you a warning that it can be used to copy data without you knowing. Confirm the action by pressing OK. When you first connect to a new computer, you'll see a confirmation request on your phone screen. RSA-The keys are to be pressed "Allow".
| Parameter | Standard value | Recommended value | Impact on the system |
|---|---|---|---|
| Scale of animation | 1x | 0.5x | Accelerates visual response |
| Background processes | No restrictions. | No more than 4. | Saving RAM on weak devices |
| Absolute level | Off | On (for Bluetooth) | Remove separate volume control |
| Show touch | Off | Off | Displays the touch point (for screencasts) |
Using ADB (Android Debug Bridge) allows you to access commands that cannot be executed through a normal interface, for example, you can remove Xiaomi system applications that are not subject to removal by standard methods, or make full data backups before flashing.
⚠️ Note: Do not leave the debugging mode on USB If you plug your phone into public charging stations, it can become a vulnerability to potential data.
You can also configure the configuration in this section. USB If you use your phone as a modem or file transfer frequently, it makes sense to change the standard "Charge Only" behavior to "File Transfer" behavior (MTP)" or"USB-modem so you don’t manually select mode every time you connect.
Memory and background management
Xiaomi devices with a small amount of RAM (3-4 GB) may have difficulty keeping applications in the background. The aggressively system closes processes to free up resources, which leads to a constant reboot of messengers or navigators. The developer menu has tools to manually control this behavior.
Find the "Applications" section and the "Background Process Limit" parameter, where you can set a limit on the number of applications that can run simultaneously. However, paradoxically, setting a hard limit (e.g., "No more than 1 process") can worsen multitasking. Better leave the "No Limit" or "Standard Limit" value, relying on MIUI optimization algorithms.
A more useful feature is Do Not Save. If you turn on this switch, the system will destroy the activity of the application as soon as the user leaves it, which is useful for testing, but in everyday life will make multitasking impossible - you can't go back to the previous application, it will open again.
Also worth paying attention to the function of forced hardware rendering (Force). GPU rendering. It forces the processor to use the graphics core to render. 2D-On older devices, this might have been faster, but on today's Snapdragon or MediaTek processors, it's just going to increase battery consumption without any visible performance gains.
Additional tools and network settings
The developer section contains a lot of network settings that can be useful in specific scenarios. For example, the Always turn on mobile Internet is useful if your Wi-Fi router does not have access to the network, but you need applications to continue to work over the mobile network without breaking the connection to the local network.
For owners of a smart home, the display option is relevant MAC-New versions of Android use randomized privacy protection MAC-address when connecting to Wi-Fi. If your router is configured to filter by MAC-In the case of white lists, you will either have to disable randomization in your Wi-Fi settings or use a static address that can also be configured in advanced menus.
What is the meaning of “Show taps”?
Another interesting option is to monitor running services, and you can see how much RAM is being used right now and what processes are consuming it, and it's a great diagnostic tool if the phone is slowing down, and you can see which app is eating up resources, and you can force it to stop.
Remember, after all the experiments, the best thing to do is to reset the developer completely. There's a button at the top of the menu that returns all the settings to factory values, which ensures that you don't forget some hidden setting that might conflict with future system updates.
