Many users of Xiaomi, Redmi and Poco smartphones are unaware that their device has hidden potential. The standard interface of the MIUI shell or HyperOS provides basic settings, but there is a layer of system functions available only to advanced users, which is hidden behind a menu item called “Developers”.
Activating this section gives you access to debugging tools, allows you to manage process power consumption, change the speed of the interface animation, and connect the phone to the computer for deep diagnostics. Developer mode is not just a toy, but a necessary tool for those who want to fully control their device.
However, interfering with system settings requires caution: Incorrectly configuring some options can lead to unstable applications or rapid battery discharge. In this article, we will discuss in detail how to safely activate hidden menus, which options should be changed first and what should not be done.
What’s Behind the Hidden Android Menu
By default, the Android operating system hides technical settings from the eyes of the average user, which is designed to protect the device from accidental changes that can disrupt its functionality. The developer menu contains a set of debugging tools originally designed for engineers and app creators.
Xiaomi owners access these features through the MIUI shell. Here you can find settings that affect processor performance, Bluetooth codecs, graphics rendering and network protocols. USB debugging is perhaps the most famous feature of this section, allowing you to transfer commands from computer to phone.
💡
Use Developer Mode only if you understand what a particular parameter is responsible for. Blindly changing values can lead to a bootloop or system malfunction.
It's worth noting that having this menu doesn't mean you have to use it every day, and most users can go without it for years, but knowing how to get there and what's there can save the day when an app refuses to work properly or requires a forced shutdown.
Step-by-step instructions for activating the mode
The process of enabling hidden settings on Xiaomi smartphones is standardized, but requires several sequential actions. Unlike some other brands, you do not need to enter special codes in the dialer, just find the desired item in the About Phone menu.
To start, open the standard Settings app and scroll down to the bottom. You're interested in the About Phone section. Inside it, you'll need to find the MIUI Version (or OS Version in newer versions of HyperOS), and that's where you want to put a series of quick taps.
☑️ Algorithm of Including Developer Mode
After the seventh press, the system will ask you to enter the unlock password or the pattern lock, a security measure that prevents children or unauthorized persons from accidentally activating the mode, and once the code is entered correctly, you will see a pop-up message: "You became a developer!"
⚠️ Warning: If nothing happens after ten taps, make sure the device does not activate guest mode or second space mode, where access to system settings may be limited.
Where to find and how to enter the developer menu
Once activated successfully, the new menu item does not appear on the home settings screen. It hides in the “Additional Settings” section. The path can look like Settings → Additional Settings → Developer.
Some versions of the firmware may have slightly different locations, so if you don't see the item right away, search by settings, type the word "developer" or "developer" into the search box, and the system will show you the path to the menu.
Inside, you'll see a long list of options grouped by category, and at the very top, there's usually an On switch that lets you instantly deactivate the entire partition, hiding it back if you're no longer planning to make changes.
Key Functions for the Normal User
Among the dozens of technical parameters, there are a few that can be useful even for an inexperienced user, and first of all, you should pay attention to the section "Drawing", which is the settings for the animation speed.
The Windows Animation Scale, Transition Animation Scale, and Animation Duration Scale are set to 1x by default. Changing this value by 0.5x visually speeds up the interface. The smartphone begins to respond to touch instantly, creating a sense of greater performance.
Another useful feature is "Show Touch," which when you turn it on, you get a white dot on the screen where you touch your finger, which is very convenient when you create screencasts, when you teach videos, or just to show the interface to other people.
Also worth mentioning is the “Do not turn off the screen” option: If it is active, the smartphone display will not go out while the device is connected to the charger, which eliminates the need to constantly tap the screen or press the power button when using the phone as a navigator or a desktop clock.
| Parameter | Standard value | Recommended value | The effect |
|---|---|---|---|
| Window animation scale | 1x | 0.5x | Accelerating the opening of applications |
| Transition animation scale | 1x | 0.5x | Quick switching between screens |
| Background process | No restrictions. | No restrictions. | Don't change it unless you need to. |
| USB-configuration | Charging. | File transfer | Automatic mode for PC |
Debugging settings and working with USB
The Debugging section contains the tools needed to interact with your smartphone and computer. USB Debugging allows your computer to access the Android system through the ADB (Android Debug Bridge) protocol, which is required to install applications bypassing Google Play, flashing or deep cleaning the system.
An important addition is the item “Debugging over USB (security settings).” It allows the computer to emulate the clicks on the screen and change the settings. Without this option, many programs for managing a phone from a PC (such as Scrcpy or Mi PC Suite) will not be able to work fully.
What is ADB and why is it needed?
The work schedule is also set up here. USB If you often connect your phone to your computer to transfer files, it makes sense to change the value «USB-Configuration from “Charging only” to “File transfer (MTP)». This will eliminate the need to choose the mode in the notification curtain every time.
⚠️ Warning: Never turn on the debugging on USB Attackers can use this port to steal data or install malware.
Memory and background management
Owners of devices with a small amount of RAM can find the settings in the "Applications" section useful. The "Inactive Applications" option allows you to limit the work of background processes, which in theory should save battery power and free RAM.
Background Process allows you to limit the number of applications running simultaneously, but modern MIUI is itself effective in managing memory. Artificial restriction can cause messengers to stop receiving notifications, and music will stop when switching tasks.
Download Services shows which system services are consuming the most resources at the moment, which can help identify the “gluttonous” application that is slowing down the entire smartphone.
There is also the Wi-Fi Aggregation option, which allows you to use both Wi-Fi and mobile network to speed up loading, which can be useful for poor signaling, but increases traffic and power consumption.
💡
Changing the limit of background processes rarely gives a tangible performance boost on modern Xiaomi models, but can be critical for devices with 2-3 GB of RAM.
Possible risks and precautions
While useful, experiments on the developer menu carry risks, the most common problem is turning on the “Always Activity Mode” function or changing the DPI (screen width) to an incorrect value, which can make the interface unreadable or completely unworkable.
If you change the DPI (Minimum Width) and the screen becomes unusable, don't panic. Usually, it helps to reboot the device in Safe Mode or reset the settings to factory if access to the menu is lost completely.
Another risk is unlocking the bootloader, and the developer menu contains the item "Factory Unlock," and activating this item and then unlocking it through Xiaomi's official website will result in the complete deletion of all data from the device, an irreversible process that is only necessary for custom firmware installation.
Do not enable features related to simulating location or disabling application signature verification if you do not understand the consequences, and this can open up access to the device for malicious code that is normally blocked by the security system.
