Xiaomi’s current smartphones, which run on the shell of MIUI or the new HyperOS, hold huge potential for advanced users. The standard settings interface offers basic features, but real control of the device only begins after the hidden menu is activated, and this is where the tools for finely calibrating the system, managing power consumption and, of course, debugging applications are located.
Many users are afraid to go into the system wilds for fear of breaking something. However, activating this mode will not delete your data or radically change the way your phone works without your knowledge. Developer mode is just a set of additional switches that are hidden by default so as not to confuse the average owner of a gadget.
In this article, we’ll take a closer look at each step of activation, look at the features of different firmware versions, and discuss what options you really need to change to speed up the interface, and learn how to turn your Redmi or POCO into a powerful tool for testing and optimization.
Why you need a developer mode on Android and MIUI
The main purpose of this menu is in the name itself. Xiaomi engineers created this section to test applications at various stages of development. However, the functionality has long gone beyond purely programming tasks. USB debugging allows you to transfer data between the computer and the phone at a deep level, which is necessary for installing customized recavers or unlocking the bootloader.
In addition to debugging, there are some useful animation settings, which means that by reducing the transition time, you can visually speed up even the most powerful smartphone, and you can also prevent the system from unloading background processes, which is critical for those who use specific applications that require constant activity.
And diagnostics, too, is a tool that displays the current RAM load, the running process information, and the wireless module statistics, which helps you understand why the battery is running faster than normal, or why applications are running out of gear.
Preparation for activation of hidden functions
Before you get into action, make sure the device is ready to make changes. While the process is safe, it is better to have a charger on hand, as some system processes can increase power consumption in a short time. Also make sure you know your screen unlock password, as the system may request confirmation.
It is important to understand that the interface may vary slightly depending on the version of MIUI (12, 13, 14) or the new HyperOS. The logic of the actions remains the same, but the names of items may vary. If you use the global version of the firmware, the menu will be in Russian, which greatly simplifies navigation.
It is recommended to back up important data in advance, although activation of developer mode does not affect user files. This is a good rule of thumb whenever you manipulate Android system settings.
☑️ Device readiness for setup
Step-by-step: how to turn on the developer menu
The activation process is hidden from the user's eyes to prevent accidental activation, and you'll need to do a series of quick taps on a specific field in the About Phone menu, which is a kind of digital key that allows you to access engineering functions.
Follow the algorithm carefully. If you didn't succeed the first time, you may have changed your pace, the system responds to rhythmic touches, and after you do it, you'll see a pop-up notification that you've become a developer.
⚠️ Warning: Do not try to change the settings in the menu that opens unless you know exactly what they are responsible for. Some settings may lead to unstable system operation or data loss.
Let’s consider the detailed procedure for current versions of the shell:
- 📱 Open the Settings app on the home screen or in the notification curtain.
- 🔍 Select About Phone (usually at the top of the list).
- 👆 Find the line "Version" MIUI» (or "Version" OS» in HyperOS) and quickly click on it 7-10 once.
- ✅ Wait for the pop-up message “You became a developer!».
After this step, the main hidden menu will be activated, but it still needs to be found in the settings list.
What to do if the counter does not appear?
Where is the developer menu after switching on
Once activated successfully, the new item will not appear on the home settings screen, but it hides in the "Advanced" sub-menu. In older versions of MIUI, the path may have been different, but in current builds, the logic is the same.
To get there, go back to the main settings menu and scroll down the list. Find the "Additional" (or "Advanced Settings") section. It's inside that that now features the "Developers" item. In some cases, it may just be called "Advanced Settings."
Inside, you'll see a warning that changing these settings could affect the device, which is a standard security plug, and if you click OK, you'll get access to dozens of settings.
| Parameter | Where to find out. | Default value |
|---|---|---|
| USB debugging | Top of the list | Off. |
| Window animation | Section "Drawing" | 1x |
| Limit of background processes | Section “Annexes” | Standard. |
| Show touch | Section "Input" | Off. |
Now that you know where the input is, you can start configuring specific features.
Configure debugging over USB and work with ADB
The most important feature for advanced users is USB Debugging, which allows the computer to control the phone, install applications around standard restrictions, and read system logs. To work with the ADB (Android Debug Bridge) tool, this switch must be active.
When you first connect the cable to your PC after you turn on this feature, you'll see a request for debugging permission on your smartphone screen. Be sure to check the RSA keyprint if you connect to your personal computer and click "Allow." Without this confirmation, the computer won't see the device in debugging mode.
adb devicesThis command in the computer's command line should output the serial number of your device if everything is set up correctly, and if you see an unauthorized number instead of a number, then you have not confirmed the request on the phone screen.
You can also include Wi-Fi debugging in this section, which allows you to connect to a device without a cable, which is convenient for wirelessly transferring large amounts of data or testing, but remember that when you work over Wi-Fi, the transfer speed may be lower and the connection less stable.
💡
When connecting to a new computer, always check your phone's screen. If you just press OK without looking at your keys, you risk giving your device access to someone else's PC in a public place.
Speed optimization: animation and memory settings
One of the most popular ways to speed up a phone is to scale up the animations, and by default, all transitions, windows and applications take a certain amount of time (usually a factor of 1.0), reducing this value makes the interface more responsive.
In the developer menu, look for the Drawing section, and you're interested in three things: Windows animation, transition animation, and animation duration. Change the value from 1x to 0.5x. Visually, the phone will work twice as fast as the waiting time for the animation to finish.
Another important section is "Apps." You can find the "Background Process Limit" setting here. The default is "Standard Limit." If you have an old phone with a small amount of RAM, you can try to limit the number of background processes to 2 or 3. This will free up resources for an active application, but can lead to more frequent reboots of background programs (for example, messengers).
- ⚡ Animation. 0.5x — the middle between speed and smoothness.
- 🛑 Setting the value 0x Makes the interface twitchy and deprives it of visual logic.
- 🧠 Restricting background processes is only useful on devices with 2-3 GB RAM.
Remember that aggressive memory optimization can cause the navigator to restart in the middle of the route, and the music to go silent when switching to another application.
⚠️ Warning: Do not completely disable system services or drivers in the Network settings section unless you plan to run specific tests.This may result in loss of communication or inability to connect to Wi-Fi.
Possible problems and solutions
Sometimes users are faced with a situation where the "For Developers" item disappears on its own or stops opening. Xiaomi has a security mechanism: if you haven't used the developer menu for a long time, the system can automatically hide it again for security.
Just repeat the procedure with a click on the MIUI version, and access will return. There are also times when after updating the firmware all the settings in this menu are reset to factory, which is normal behavior of the system, as new versions of the software can change the structure of hidden parameters.
If you can't turn on USB debugging (the switch immediately turns off back), check if the phone is connected in Charge Only mode. Switch USB mode to File Transfer (MTP) and try again.
💡
Automatically hiding the developer menu after a period of inactivity is a regular MIUI security feature, not a system bug.
