Xiaomi’s modern smartphones offer users a wide range of customization options that go far beyond standard interface settings, but many of these features, such as speeding up interface animations, debugging applications in detail, or managing background processes, are hidden in a special section that is not available to the average user by default: the Developer Options menu, which is initially hidden by the developers of MIUI and HyperOS to avoid accidentally changing critical system settings.
Activating this section gives you access to tools that not only fine-tune your device to your needs, but also solve a number of software problems. For example, many users use these settings to force you to close your frozen applications or to connect your smartphone to your computer in deep debugging mode. Turning on the developer mode is a safe procedure, if you understand what changes you are making to the operating system.
In this article, we will take a closer look at all the steps of activating the hidden menu, look at the basic features available after unlocking, and give recommendations for the safe use of advanced settings. Whether you are an experienced enthusiast or just want to speed up your gadget, understanding these processes will allow you to squeeze the most out of your device.
Why you need a developer mode and what opportunities it opens
The Developer Options section is a hidden menu on the Android operating system that contains a set of tools for debugging and testing applications, originally designed for programmers developing software for the Android platform, but over time, ordinary users have appreciated the convenience of some features that allow you to manage the behavior of the system more flexibly than possible through the standard settings menu.
One of the most popular features is the ability to control the speed of animation windows. Xiaomi’s standard settings often make transitions between screens smooth but slow, which visually creates a sense of “stiffness” interface. Changing the scale of the animation allows you to make the system response visually instantaneous. USB-debugging, which is necessary to install applications from a computer or use specialized software to control the phone.
⚠️ Attention: Changing the settings in the Developer section, which you do not have a complete idea about, can lead to unstable system operation or failures in individual applications.
Also in this section, you can find information about running services, manage background limits, and even emulate a location for testing geo-dependent applications. Enabling developer mode does not void the device warranty or require root rights. It is a regular Android feature, just hidden from the eyes of the average user.
- 🚀 Speeding up the interface by changing the speed of animation windows and transitions.
- 🔌 Activation of the debugging mode USB for communication with PC and data transfer at a low level.
- 📱 Forced management of background processes and services to release RAM.
- 🎨 Color space setting and simulation of additional displays for calibration.
Step-by-step: how to activate the hidden menu on Xiaomi
The process of activating the hidden menu on Xiaomi, Redmi and POCO smartphones is unified and takes no more than a minute. You do not need to connect the device to a computer or use third-party software. All actions are performed directly through the Settings app, which is preset on each device. It is important to follow the sequence of steps carefully, since the names of items may differ slightly in different versions of the firmware, but the logic remains the same.
To start, open the main settings menu for your smartphone, you need to find a section called About Phone or About Device, which is usually at the top of the list, and this is where you get all the technical information about the model, Android version and MIUI build number. We need the line MIUI Version (or OS Version in new firmware).
☑️ Activation algorithm
Make 7 quick, sequential clicks on the version number line. After the third or fourth click, the system can request the unlock password or pattern lock, which is a security measure. After successfully entering the password, continue pressing. Once the limit is reached, you will see a pop-up notification "You became a developer!". From now on, a new hidden section will appear in the settings menu.
To get into it, go back one step to the main settings menu. Depending on the shell version, the new item may be called "Additional" or "Extended Settings." Inside, you'll find "Developer Options." If you're searching by settings, just type in the word "Developer," and the system will show you the way.
What to do if the menu does not appear?
Configuring debugging over USB and working with a computer
One of the key features for which users most often activate the developer mode is debugging. USB (USB Debugging: This protocol allows a computer to access the Android system through the Android debugging interface (ADB). This is necessary for installing applications outside the Google Play store, flashing the device, removing error logs or using programs to deep clean the system.
To enable this feature, go to the Developer Options menu and find the USB Debugging Switch. When you first turn on, the system will give a warning about potential security risks. You must confirm the action. Once you connect your smartphone to your computer with a cable, a request will appear on the device screen for debugging permission from that computer. It is recommended to tick the “Always Allow from this computer” box so that you do not confirm the action every time you connect.
| Parameter | Description of function | Recommended value |
|---|---|---|
| USB debugging | Allows debugging when connected via USB | On (if necessary) |
| USB configuration by default | Action when connecting the cable (charging, transferring files) | File Transfer (MTP) |
| Wi-Fi debugging | Wireless application debugging | Off (for battery saving) |
| Select an emulation application | Forced start of selected software in the emulator | Not selected. |
It's important to understand that USB debugging on makes the device more vulnerable when connected to other people's computers or public charging stations. Attackers can access data or install malware. So if you're not using debugging right now, it's best to keep that switch off.
💡
Use only original or certified cables to connect to your PC. Cheap cables without shielding can cause data transmission errors when USB debugging is enabled.
Optimizing the interface: accelerating animation and graphics
Xiaomi smartphone owners often complain that MIUI doesn’t work as fast as they’d like. Often the problem isn’t with weak hardware, but with over-animating transitions. The developer section has three parameters that control window rendering speed: “Window animation,” “Change animation,” and “Duration animation.”
By default, all of these values are set to "1x" (single speed). Changing this parameter to "0.5x" visually speeds up the system by twice. Windows open instantly, lists are flipped faster, and you feel highly responsive. Some enthusiasts try to turn off animations completely (meaning "No animation"), but this can make the interface twitchy and less pleasant to perceive.
Also in this section you can find settings related to hardware acceleration, such as the function "Disable overlay" HW» (Disable HW overlays GPU On older devices, this can improve performance in games a little bit, but it will lead to increased battery consumption. On modern processors Snapdragon and MediaTek the difference is almost not noticeable, so experiment with these settings is only in the presence of specific problems with the display of graphics.
- ⚡ Setting the value 0.5x For all types of animation, the best way to speed up UI.
- 🎨 Enabling “Strict Mode” helps identify applications that slow down the system.
- 📉 Disabling unnecessary visual effects can extend battery life.
⚠️ Warning: Do not change the settings associated with Smallest Width unless you are sure of your actions. DPI) It can make interface elements so small that you can’t return settings back without a data reset.
💡
Optimal tuning of animation to 0.5x gives a noticeable increase in the speed of the interface without loss of visual smoothness and comfort of use.
Memory and background management
Android is famous for its efficient RAM, but the MIUI shell has its own aggressive optimization features. In the developer settings, you can manually limit the number of background processes. The Background Process Limit feature allows you to choose how many applications can remain active in memory when you are not using them.
Setting a limit of "No background processes" or "No more than 1 process" can free up a significant amount of RAM. This is true for devices with 3 or 4 gigabytes of RAM, where every megabyte counts. However, it is worth remembering that after such a setup, when switching between applications, they will reboot again, which can increase the power consumption of the processor and slow down multitasking.
It also has a Do Not Stay Activity feature, which if enabled, will destroy activity (app screen) as soon as the user switches to another task, useful for testing how the app recovers, but in everyday use will make the smartphone extremely uncomfortable, as no application will keep your progress.
adb shell dumpsys meminfoThis command, which is typed through a computer when debugging is enabled, shows detailed statistics of memory usage by each process. Combined with manually controlling limits in the phone's settings, it's a powerful tool for finding memory-eating applications that aren't visible in the standard task manager.
Additional debugging tools and functions
Beyond the basic features, the developer menu hides a number of specific tools, such as enabling real-time frame rate (FPS) display on the screen, which is useful for gamers who want to evaluate the smoothness of games, or users who are checking the impact of a new firmware version on performance.
Show taps displays a white circle at the point where you touch your finger, which can be useful when creating screencasts or training videos to let viewers see where you click, and it also includes the option of turning on a location indicator, which is convenient for navigating in maps, but can be annoying in normal mode.
Another interesting thing is location emulation, and you can choose an app that will provide fake data. GPS-This allows you to “move” to other cities and countries, which can be useful for testing geo-dependent services or games, although using this for cheating in online games can lead to the blocking of your account.
- 📍 Location emulation allows you to test applications without physically moving.
- 📊 Monitoring FPS It helps to assess the real performance of the graphics processor.
- 👆 Displaying touches is useful for creating instructions and training materials.
