Modern Xiaomi and Redmi smartphones are built on the Android operating system, which hides from the average user a lot of advanced tools. One of these hidden sections is the developer menu, which gives access to deep system settings. Many device owners are looking for a way to enter the developer’s settings on Android Xiaomi to activate debugging over USB, rescaling fonts or ban background services to save charge.
By default, this section is hidden so that inexperienced users do not accidentally change critical settings that can disrupt the stability of the gadget. However, for enthusiasts and those who want to make the most of their Mi or Poco, access to these features is simply necessary. In this article, we will discuss in detail the algorithm for activating the hidden menu, consider key parameters and discuss precautions when working with system variables.
Before making any changes, it is important to understand that you take responsibility for the stability of the operating system. Incorrect configuration of some parameters can lead to incorrect display of the interface or even loss of data. However, the competent use of debugging tools allows you to significantly speed up the device and improve the user experience.
Why you need a developer menu on Xiaomi
The main purpose of the hidden section is to provide engineers and programmers with tools to test applications and debug code. However, ordinary users find features here that are useful for everyday use. For example, you can force the background processes to close, which frees up RAM and can improve performance in games. It also provides a feature of forced rendering via the GPU, which speeds up the processing of graphics in heavy applications.
Another popular feature is changing the speed of the interface animation. Standard values in MIUI and HyperOS often seem to be stretched, creating the illusion of smoothness, but slowing down the response of the system. By reducing the scale of animation of windows and transitions, you visually speed up the smartphone, making it more responsive to touch. This is especially true for low-end models with entry-level processors.
⚠️ Warning: Changing the values associated with the minimum screen width can lead to the fact that the interface elements become too small or, conversely, giant, and it will be difficult to return everything back without resetting the settings.
In addition, it is in this section that the USB debugging mode is activated, which is necessary for installing applications not from official sources, flashing the device through a computer or using advanced tools like ADB. Without enabling this option, the computer simply will not see the smartphone in control mode, but only as a drive.
- 🚀 Interface Acceleration: Changing animation speed makes the system work visually faster.
- 💾 Memory Management: The ability to limit the number of background processes for release RAM.
- 🔌 Debugging by USB: A mandatory step to connect to a PC in developer mode and transfer high-level files.
- 🎮 Game settings: activation 4x MSAA Improved graphics in games (requires a powerful iron).
It is important to note that the functionality may vary slightly depending on the version of the MIUI shell or the new HyperOS. In more recent versions of the firmware, some items may be renamed or moved, but the logic of the work remains the same. Understanding the purpose of each parameter will help avoid errors and customize the device to your personal preferences.
Step-by-step instructions for activating the developer mode
The process of turning on the hidden menu on Xiaomi smartphones is standardized and takes only a few seconds. You do not need third-party apps or root rights. All actions are performed through the standard Settings app. The main thing is to be careful when counting clicks, since the system requires an exact number of activations to confirm the user’s actions.
To start, open the main settings menu of your device. Usually, the icon is a gear. Find a section called About Phone or About Device. It's usually at the top of the list, and that's where all the technical information about your gadget, including the build number, is contained.
☑️ Activation checklist
Inside the About Phone section, you need to find the MIUI Version line. This is the line where you need to use a series of quick fingerstrokes. Make 7-10 quick taps. After 3-4 times, the system can show a pop-up message "Push 4 more times" that confirms that you are correct. If you have a screen unlock password or a pattern lock, the system will ask you to enter it for confirmation.
Once you successfully enter your password, you will see a notification saying, “You’ve become a developer!” which means that the hidden partition is activated. Now, to get into it, you need to go back to the main settings menu and go to the “Additional” section (or “Extended settings”, depending on the shell version), and there will be a new item “Developers”.
| Step. | Action. | Expected output |
|---|---|---|
| 1 | Open Settings | Main menu of system parameters |
| 2 | Choose About the Phone | Screen with technical information |
| 3 | 7 times to press the "Assembly Number" | The message is “You became a developer” |
| 4 | Enter the lock password | Confirmation of activation of the mode |
| 5 | Go to Additional Settings | Appearance of the item “For developers” |
Note that some global firmware versions may have slightly different paths, such as MIUI 14 or HyperOS, which may simply be called “Special Features” depending on localization, but the “Build Number” line remains the unchanging key to activating the engineering menu across all brand devices.
Configuring debugging over USB and working with a computer
One of the most popular features for advanced users is USB debugging, which allows a computer to access the system commands of a smartphone, which is necessary not only for application developers, but also for ordinary users to install specialized software, remove system logs or unlock the bootloader.
To activate this feature, log in to the Developer menu. Find the USB Debugging switch and activate it. When you first turn on, the system will issue a security alert. You have to agree to it. Once you connect the cable to your computer, you will see a request for debugging permission from that computer on your smartphone screen, and you must tick "Always Allow" and click "OK."
Why can't the computer see the phone?
It's important to understand the difference between normal file transfer and debugging. In normal mode, the computer sees only internal memory and the SD card as external drives. In debugging mode, you open command-line ports that allow you to manage the system at a deeper level, which can be used to install applications bypassing Google Play or to reset a forgotten password through specialized utilities.
Security when working with debugging is a critical aspect. Never turn this mode on a permanent basis unless you are using it right now. Connecting a smartphone with active debugging to someone else's computer or a public charging station (juice jacking) can theoretically allow attackers to access your data.
- 🔒 Secure Connection: Always Check Requests RSA-keys when connecting to new PCs.
- 📱 Drivers: drivers may be required for Windows debugging to work properly ADB Interface.
- ⚡ Energy consumption: Active debugging can slightly increase battery consumption due to constant port surveys.
If you plan to use your smartphone to debug your applications, also look at the option “Select a debugging app.” Here you can choose a specific process that will be monitored, which is convenient when developing software. For the average user, it is easy to turn on and off the main debugging switch as needed.
Optimizing system speed and performance
Once you activate the developer mode, you have a whole arsenal of tools to speed up the interface. Visual speed is what the user notices first. Standard animations in Android last about 300-500 ms, which creates smoothness, but on powerful screens can feel like a delay.
Find the section related to drawing in the list of parameters. You're interested in three items: "Window animation", "Jump animation" and "Duration of animation." By default, they are set to "1x." Change each of them to "0.5x." This will reduce the time of rendering transitions by half. The interface will fly, the reactions to presses will become instantaneous.
⚠️ Attention: Setting the animation value in "No Animation" can make the interface twitchy and less pleasant to perceive, as smooth transitions between screens disappear. 0.5x.
Another powerful tool is to limit background processes. In the Applications section, look for the "Background Process Limit" option. The default is "Standard Limit." You can choose "No More than 1 Process" or "No More than 2 Processes." This will cause the system to aggressively close applications that you've folded, freeing up RAM for an active task, which is especially useful on devices with 4GB of RAM or less.
Be careful, though: too tight a restriction on background processes can disrupt messengers (messages will be delayed) and navigators. If you notice notifications stopped arriving on time, return the standard limit. There is also a Do Not Save Action feature that completely clears the activity of the application when you leave it, but it is rarely needed in everyday use.
What's interesting to gamers is the 4x MSAA, which makes the GPU render graphics with higher anti-aliasing quality, which improves the image in games by making the edges of objects less jagged, but remember, turning on this feature significantly increases the load on the processor and battery, causing the device to heat up, and use this only in heavy games and if you have good cooling.
Networking and Bluetooth in the Engineering Menu
The developer section includes not only interface settings, but also important network settings. Here you can find tools to diagnose connection problems. For example, "Bluetooth logging" allows you to include detailed logging of the communication module, which is useful if you have problems connecting headphones or smartwatches, and you plan to send an error report to support.
Also available here is the "Absolute Volume Level" feature, which in standard Android mode, the volume of the phone and Bluetooth device (e.g., headphones) is independently or synchronously adjusted, but not always predictable. Turning on this setting causes the system to consider the maximum volume of the phone and headphones as a single value, this solves the problem of quiet sound in headphones when the phone is twisted to the maximum, and the headphones are still quiet.
An important parameter is, "Mobile network is always active." If this feature is enabled, the smartphone will not switch to Wi-Fi to transfer data, even if the Wi-Fi is connected while the screen is off. This can be useful for maintaining a stable connection in messengers, but consumes more traffic and energy. For most users, it is better to leave this option off to save charge.
Modern versions of MIUI also feature Wi-Fi-based scanning settings, and even when Wi-Fi is turned off, the system can periodically scan the airwaves to improve geolocation, and in developer mode, you can find more detailed network stack behavior settings, although Google is gradually hiding these capabilities in recent Android versions for the sake of security and energy efficiency.
- 📶 Absolute volume: solves the problem of quiet sound in Bluetooth headsets.
- 📡 Aggressive Switching: Settings help you choose a stable Wi-Fi network when you have multiple access points.
- 🌐 DNS: taskability DNS to bypass the provider’s locks (although this is also the case in normal settings).
If you find Wi-Fi Internet running slowly and mobile Internet running fast, try the developer menu to find a network reset. Sometimes it helps to temporarily shut down IPv6 if your provider does not properly support it, although this option is not available in all firmware.
How to turn off the developer menu and reset the settings
Once you've done all the necessary manipulations, you can and should turn off the hidden menu, which will return the system to its standard appearance and protect against accidental changes in the future, and it's very simple: just go back to the "Developers" section and turn off the master switch at the top of the screen.
Once you turn off the switch, all the parameters you have changed (animation speed, process limits) will return to factory values. The "Developers" item will disappear from the "Additional Settings" menu. If you want to access these features again, the procedure will have to be repeated with the click on "Build Number".
In some cases, if the system is not stable after experimenting with settings, you may need to completely reset the developer settings. At the bottom of the developer menu, there is a button called Reset, which returns all the parameters inside this section to the original state, but does not affect your personal files, photos or installed applications.
💡
Save screenshots of important settings before resetting: If you have been setting complex settings for specific tasks, take a screenshot before reset so you don’t look for values again.
Remember that the developer menu is a powerful tool, not a toy. Regularly turning on and off functions without understanding their purpose can lead to unpredictable behavior of the system. If you are not sure what a particular parameter is responsible for, it is better to leave it unchanged or search the Internet for the exact name of the function.
⚠️ Attention: Factory Unlocking Function» (OEM Unlocking in the developer menu is designed to unlock the bootloader. its inclusion without prior binding of the Mi Account and waiting 168 hours (7 days) can lead to locking the device or loss of warranty.
Competent use of the capabilities of Xiaomi allows you to turn a standard smartphone into a personalized tool that works exactly as you need. Experiment with caution, and your gadget will respond to you with high performance and convenience.
