Enabling hidden system features is the first step to deep personalization of your smartphone. Many Xiaomi, Redmi and POCO users are faced with the need to activate the developer mode to debug applications, change the animation speed or gain advanced control over the system. This option is hidden by default from the eyes of the average user to prevent accidental changes in critical settings that can disrupt the stable operation of the device.
Activating this section doesn't require root rights or complex software. It's enough to do a few sequential actions in the standard settings menu. However, it's important to understand that you're accessing tools designed for engineers, so every change should be conscious. In this article, we'll go into detail about the activation process, look at key parameters, and explain the risks that can arise from improper handling of system functions.
It is worth noting that the interface of the MIUI shell or the new HyperOS may vary slightly depending on the version of Android and regional firmware. Despite the visual differences, the activation logic remains the same for all modern models of the brand. Before starting the procedure, make sure that the battery charge of your gadget is at least 20% to avoid turning off during manipulation of system files.
Why you need a developer mode and what opportunities it gives
The main purpose of this section is to provide tools for testing and debugging applications by programmers, but advanced users often use these features to optimize the performance of a smartphone. For example, rescaling the animation of windows allows you to visually speed up the interface, making transitions between screens more instantaneous, this is especially true for budget models, where every millisecond of the CPU response matters.
Another important feature is USB debugging, which allows you to transfer data between your computer and smartphone at a low level, install applications directly from ADB, make full system backups, or even reflash the device in case of critical failures. Without activating this point, most computer utilities for working with Android devices simply will not see your phone in the appropriate mode.

Use Developer Mode to force GPU rendering in older games – this can boost FPS but increase battery consumption.
And it also has settings related to location, Bluetooth, and network protocols, so you can prevent applications from scanning Wi-Fi in the background, which will have a positive effect on autonomy, and you can also select a specific Bluetooth codec to improve the sound quality when you connect wireless headphones, if the hardware of the device supports it.

- 🔌 The ability to connect the debugger and work with ADB-team.
- 📡 Fine tuning of network modules and Bluetooth codecs.
- 📊 Monitoring of running processes and using memory in real time.
Step-by-step: how to activate the hidden menu
The process of enabling hidden options on Xiaomi devices is as unified as possible. You do not need to download third-party launchers or use a computer. All actions are performed directly in the smartphone settings menu. The main thing is to carefully monitor the number of clicks, since the system of protection against accidental activation requires accurate hitting the counter.
To start, open the main settings menu for your device. Find a section called About Phone (or About Phone). At the top of the screen, you'll see the logo of the operating system version (such as MIUI 14 or HyperOS) and the build number. This is the field you need to apply a series of quick touches to.
☑️ Activation algorithm
Start quickly clicking on the Build Number. After the fifth click, the system can alert you that you are becoming a developer. Continue to click until the message "You are a developer!" If the device has an unlock password or PIN-code, the system will ask you to enter it to confirm the action, after successful verification, a new item will appear in the settings menu.
⚠️ Note: If nothing happens after 10 clicks, you may have child protection or a limited user profile enabled that blocks system settings from changing.
Now go back to the main settings menu. Scroll down to the Additional section (some firmware versions may call it Advanced Settings) and there you will find a new menu item, Developer's, and you will see a long list of technical options available for editing.
Configuring debugging over USB and working with a computer
One of the most embedded features in this section is USB debugging. It is disabled by default for security reasons so that attackers cannot access your phone data through public charging stations. To activate, find the USB Debugging Switch and turn it into the "On" position.
When you first connect a smartphone to a computer, you'll see a request for debugging permission on the screen, and you'll be shown the digital key (RSA-You have to click "Allow" and preferably "Always Allow" from this computer, so you don't have to confirm the action again, and this is critical for automated scripts or screencasting software.
adb devices

- 🔒 Disabling debugging in public places for data protection.
- 💾 Choice of regime USB (only charging, transfer of files, MIDI).
- 📡 Wireless debugging for working with ADB cableless.
- ⏱ Timeout waiting for the debugger connection.

Optimization of the interface and acceleration of the system
Visual speed of a smartphone is often subjective and depends on the duration of animations. In the standard state, MIUI uses 1x coefficients for all transitions. By changing these values, you can make the interface more responsive.
It's recommended to set a 0.5x value for all three parameters. This will cut the opening and closing times of applications in half, creating the illusion of a more powerful processor. Some users are experimenting with a value of 0x, turning off animations completely, but this makes the interface dry and twitchy, and can also lead to visual artifacts when switching tasks.
💡
The optimal value of animation is 0.5x. Full shutdown (0x) often looks worse than standard animation and does not give a proportional increase in performance.
Also in this section is the function Forced hardware acceleration. GPU render 2D-It can help with gaming on older devices, but on modern processors, the effect is almost invisible, and the energy consumption can increase. Be careful with the “Do Not Stay Activated” feature – it will kill the app immediately after you leave it, which is useful for testing but terrible for everyday use.
| Parameter | Standard value | Recommended value | Impact |
|---|---|---|---|
| Window animation | 1x | 0.5x | Accelerating the opening of applications |
| Animation of transitions | 1x | 0.5x | Quick switching between screens |
| Duration of animation | 1x | 0.5x | Menu speed and curtains |
| Background process | Standard. | No restrictions. | The work of messengers in the background |
Working with memory and background processes
The developer section provides tight control over RAM (RAM). The background process limit feature limits the number of applications that can remain active in a folded state. While it is tempting to put a "process 1" limit on freeing up memory, it will result in constant rebooting of applications (such as a navigator or music) with each return to them.
For most users, the best choice is Standard Limit or No Limits. Modern memory management algorithms in Android are more effective than manual constraints. However, if you have a specific application that crashes immediately after you fold, you can try adding it to exceptions or changing the overall limit.
Also available here is the Memorization activities function, which, if enabled, tries to keep the state of the application as long as possible, and only helps developers who test the behavior of the application when memory is scarce, and it is better for the average user not to touch these settings so as not to disrupt the multitasking system.
⚠️ Warning: Forced stop of background processes may cause you to stop receiving notifications from messengers until the application is manually opened.
Network settings and Bluetooth codecs
At the bottom of the developer menu, you can use the network technical settings, you can turn on the real-time connection speed display in the status bar, which is convenient for monitoring communication quality, and you can also use the "Always turn on mobile data" feature, which keeps 4G/5G active even when you have Wi-Fi connected for a faster switch.
For audiophiles, the Bluetooth Audio Codec section is interesting. If you use high-quality wireless headphones, you can force the audio transmission codec to choose: SBC, AAC, aptX, LDAC or LHDC. Choosing a higher-quality codec (for example, LDAC) will significantly improve sound detail, but can reduce headphone time and increase latency in games.
- 📶 Displaying Wi-Fi speed and mobile network.
- 🌐 Selection of preferred network (5G/4G/3G).
- 🎧 Switching Bluetooth codecs (SBC, AAC, aptX).
- 📡 Aggregation of Wi-Fi channels to increase stability.
There's also the option to turn on the absolute volume level, which links the volume of the phone to the volume of the Bluetooth device, and if you have quiet headphones, turning on this feature can help you get the most out of them, synchronizing the adjustment sliders.
