How to open a developer menu on Xiaomi: the complete guide

Xiaomi’s current smartphones, running the MIUI shell or the new HyperOS, are powerful devices that hold huge potential for power users. The standard settings interface is often limited to basic features that the average person needs, but enthusiasts and technicians need access to deeper layers of the Android operating system. This is where the hidden section comes to the scene to manage system processes, adjust animation speeds and activate debugging mode.

Many gadget owners are wondering how to activate this functionality without violating the warranty and without resetting the device to factory parameters. The activation process does not require root rights or complex software on the computer, everything is done by the regular means of the smartphone itself. However, it is worthwhile to understand that interference with system settings requires caution and a clear understanding of actions.

In this article, we will discuss in detail the algorithm for activating the hidden mode, consider possible problems when it is turned on on on different versions of firmware and discuss what parameters should be changed to speed up the interface. You will learn about the nuances of working with ADB and understand why this feature is even needed in everyday use.

Why you need a developer mode and what opportunities it gives

The hidden partition in the system is primarily for application creators and software engineers, but it can also be very useful for the average user to fine-tune the interface, for example, changing the scale of the font or the minimum width of the screen allows you to adapt the picture to individual preferences, which is especially true for models with large diagonals.

One of the most popular features is USB debugging, which allows you to connect your smartphone to your computer not just as a drive, but as a full-fledged command-transfer device, which is necessary for installing applications directly from ADB, removing system logs when errors occur, or using advanced utilities to manage the file system.

Also in this section are settings that affect the visual perception of the operating system, changing the speed of animation of windows and transitions creates the illusion of faster response of the processor, and you can also prevent the system from closing background applications or, conversely, severely limit their number to save battery power.

• 🚀 Speeding up the interface by changing animation coefficients.
• 🔌 Activation of debugging by USB for PC communication and data transmission.
• ⚙️ Managing Background Processes and Limits of Launched Applications.
• 📡 Set up network, Bluetooth and location settings for testing.

It is important to note that some features can be hidden or renamed depending on the version of MIUI. Chinese firmware versions often have a more extended list of available options compared to global builds.

Step-by-step: how to activate the hidden menu

The process of turning on the developer mode on Xiaomi and Redmi smartphones is standardized, but requires a certain sequence of actions. You do not need third-party programs, the whole procedure takes no more than a minute.

To start, open the standard Settings app and scroll to the bottom of the list. Find the About Phone (or Device) item and click on it. It displays all the basic information about the model, Android version and MIUI shell.

At the top of the screen, you'll see the logo of a version of the system, like MIUI 14 or HyperOS 1.0. You need to quickly press this logo 7 times in a row. You don't have to do it at a frantic pace, enough rhythmic presses.

After a few clicks, the system will start counting the remaining attempts. If the device has a password or a pattern lock, the system will ask you to enter it to confirm the action. After successful entry, a pop-up message will appear "You became a developer!".

⚠️ Note: If you do not have a password to unlock the screen, the system may require you to create it before activating the developer mode for security reasons.

Now that the mode is activated, the new section will appear in the settings menu, and on older versions of MIUI it will be in the “Additional” section, and on newer versions (starting with MIUI 12.5 and higher) it will be moved to “Advanced Settings”, where you will find a full list of engineering options.

Where to find the developer menu after switching on

After successful activation, many users are lost because a new icon or item does not appear on the desktop, all hidden mode settings are integrated into the system's general settings menu, and the location of this item has changed with the release of new versions of the shell.

On current firmware versions, the search algorithm is this: go back to the main Settings menu, then select the "Additional Settings" section, and that's where, among the gestures, special features, and language items, "Developer Mode" is located.

If you have an older model or Android version below 9, try looking under Advanced Settings. In some cases, especially on tablets or specific modifications, the path may lie through the System Apps menu.

Inside, you'll see a long list of parameters sorted by category, and at the top, there's usually a switch that allows you to completely deactivate, and if you accidentally turn on an extra function, just put the switch back in its original position.

Customize animation speed to speed up the interface

One of the first settings users change after activating the mode is the animation speed. By default, the system uses a 1x factor, which provides smoothness, but can visually slow down work on budget processors.

In the Drawing section (or System), find three options: Windows animation, transition animation, and animation duration. Changing the value from 1x to 0.5x makes the interface more responsive. The sense of speed increases as the time for rendering transitions between screens is reduced.

💡

Don't set the animation to 0x (off). This can lead to sharp, jerky transitions and impair the visual perception of the interface. Optimally 0.5x.

It’s worth noting that the decrease in animation does not increase the actual performance of the processor, but subjectively speeds up the work. On devices with a high hertz screen (90 Hz or 120 Hz), the effect may be less noticeable, but still present.

If the interface is unstable or artifacts appear after the settings change, just return the default values. This is safe and does not require rebooting the device, the changes take effect instantly.

Debugging with USB and working with ADB

USB Debugging is key to deep-level smartphone-computer interaction, allowing commands to be sent via the Android Debug Bridge protocol, which is needed to install system applications, capture screenshots in real time, or unlock the bootloader.

When you first turn on this option, the system will give you a warning about potential security risks. Confirm the action. Now, when you connect the cable to the PC, you will see a request for debugging permission from this computer on the smartphone screen. You must click "Allow" and, preferably, tick "Always Allow from this computer."

⚠️ Warning: Do not turn on debugging by USB When connecting to public charging stations at airports or cafes, attackers can access your data through this port.

To work with the command line on the computer must be installed Xiaomi drivers and platform tools ADB. After connecting and confirming on the screen of the smartphone, the computer will determine the device.

adb shell wm density 400

The above command is an example of changing the screen density (DPI) through ADB. There is also a Minimum Width item on the developer menu that lets you do the same without a computer, but through ADB it is often more reliable.

Possible problems and solutions

Despite the simplicity of the procedure, users may encounter a number of difficulties: often after 7 clicks nothing happens, or the menu item disappears after a reboot, this may be due to features of a particular firmware version or errors in the system.

If the tap counter doesn't show up, try clearing the Settings app cache first. Go to Apps → All Apps → Find Settings → Clear → Clear the cache. After that, try again.

In some cases, especially on Chinese versions of firmware with a global account, insertion may be required. SIM-Also make sure that the device is on the Internet, as the system can check the status of the Mi Account account.

Another common problem is that you can't enable debugging over USB. If the slider immediately returns to off, check if the device is connected to the computer at that point. Debugging permission can often only be given when the cable is disconnected.

Security and whether to turn off the mode after use

The only thing that matters is security when a developer is active: if you lose your phone or it falls into the hands of an attacker along with a trusted computer connected, and in other situations, the mode itself does not pose critical threats.

However, if you don’t use debugging features all the time, it’s best to keep the switch at the top of the menu in the off position, which will prevent important parameters such as the background process limit from accidentally changing, which can lead to messaging.

For ordinary users, the optimal scenario is to turn on the mode to change the animation, and then turn it off completely, which ensures the stability of the system and the absence of unnecessary background services consuming resources.
