Owners of Xiaomi, Redmi and POCO smartphones often face the desire to gain deeper control over the device. Standard system settings limit access to a number of critical functions necessary to fine-tune and speed up the gadget. Enabling the developer mode opens access to hidden Android parameters, allowing you to manage animations, check the load on the processor and customize interaction with the PC.
This is not a random feature, but it's a tool that's needed for advanced users, and the developers of MIUI and HyperOS are hiding it so that inexperienced users don't accidentally change the system settings, which could cause the device to run in an unstable way. But for advanced users, it's a tool that takes only a minute to activate, but it takes care, because the shell interface can change depending on the firmware version.
In this article, we will take a detailed look at all the activation steps, assign key parameters, and answer frequently asked questions, learn how to safely experiment with the system and what settings are really worth changing for everyday use.
Why You Should Hide a Developer Menu
Developer Mode is a set of tools for debugging the Android operating system, designed primarily for app creators and testers who need to test programs on real devices, not just emulators. For the average user, having this menu in the open access carries certain risks.
Changing the settings in this section can have unpredictable consequences, such as disabling certain services can disrupt standard applications or cause a “boot loop” (cyclical reboot), which is why Xiaomi, like other manufacturers, hides this section by default.
⚠️ Warning: Changing the settings you don't know in the developer menu can lead to loss of warranty or unstable system operation. Be careful when changing settings that you don't understand the meaning of.
One of the main functions for which users are looking for a way to include a developer on shaomi is debugging by USB. It allows you to transfer data from computer to phone and back at high speeds, install applications directly through the phone. ADB-commands and make full backups of the system.
Step-by-step activation instructions for MIUI and HyperOS
The process of enabling hidden menus on Xiaomi smartphones is unified, but the names of items may differ slightly in different versions of the shell. In modern versions of MIUI 12, 13, 14 and the new HyperOS, the algorithm of actions remains almost identical.
First, you need to get into the basic settings of the system: find the Settings icon on the desktop or in the notification curtain. Next, follow a clear algorithm to activate the hidden mode.
- 📱 Open the Settings app and scroll to the bottom of the About Phone section.
- 👆 Find the line Version MIUI (HyperOS version, where the build number is specified.
- 🔨 Quickly click on this line. 7-10 successively.
- ✅ Wait for the pop-up notification “You became a developer!".
After doing this, the system will unlock access to the new partition. If you didn't click fast enough or took too long a break between clicks, the counter will reset, and the procedure will have to start again. PIN-code SIM-map.
☑️ Verification of mode activation
Where to find the developer menu after switching on
Many users activate the mode, but can't find where it went. Unlike "pure" Android, where a partition can appear in different places, in the Xiaomi shell, the path to it is strictly defined. Once activated successfully, it appears in the same menu where you searched for the firmware version.
Back to the About Phone menu. Immediately below the MIUI line, a new item will appear called Additional (in some versions it may be called Advanced Settings or simply Additional), and that's where the submenu is hidden.
The search algorithm looks like this:
- Go to Settings.
- Choose About the Phone.
- Click on the block Additional.
- Select the item for developers.
Now you'll see a very large list of parameters, and by default, the master switch at the top of the screen will be activated, so you can control debugging, select a touch input emulator, and adjust background processes.
What to do if the menu is missing?
Configure debugging over USB and work with ADB
One of the most popular features for enthusiasts is USB Debugging, which allows the computer to gain full access to the file system and command line of the smartphone, which is necessary for installing custom recavators, unlocking the bootloader or removing system debris.
To activate, find the developer menu switch Debugging by USB And you turn it on. It'll give you a risk warning, OK, the first time you connect to a new computer, you'll see a confirmation request on your phone. RSA-Without the confirmation of this request on the smartphone screen, the computer will not see the device in debugging mode.
Important settings are also available in this section:
- 🔌 Configuration USB Default: allows you to choose how the phone behaves when connecting the cable (charging only, transferring files, MIDI).
- 🛡️ Protection through ADB: Requires confirmation of each connection, which increases data security.
- ⚡ USB-modem: allows you to distribute Internet from smartphone to PC via cable, which is often more stable than Wi-Fi.
If you plan to use your smartphone to test applications, you can also turn on the screen rotator for the emulator or choose a specific debugging application so as not to output system logs constantly.
| Parameter | Function | Recommendation |
|---|---|---|
| USB debugging | Communication with PC via ADB | Include only when necessary |
| Factory unlocking | Removal of loader locks | Just for flashing. |
| Window animation | Interface speed | Can be reduced to speed |
| Background processes | Limitation of application | Leave the "Standard Limit" |
Optimization of the interface and acceleration of work
The most popular way to use the developer menu for ordinary users is to accelerate the visual response of the system. Android by default uses animations for smooth transitions, but on older devices or if you want maximum responsiveness, they can be reduced.
Find the Drawing (or Drawing) section, and you're interested in three things: Window animation, Transition animation, and Duration of animation, which are 1x by default.
Change the value of each of these three parameters by 0.5x. This will make the interface visually twice as fast as it will reduce the time spent opening and closing applications. Set the value off is not recommended, as the interface will become twitchy and less pleasant to perceive.
⚠️ Warning: Don't set the font scale or minimum width in this section unless you understand the implications.This can make the interface unreadable, and it's hard to get it back without resetting the settings.
It also has a feature called Touch Show, which includes a white dot where you touch the screen, which is useful for creating screencasts or teaching older people how to use a smartphone so you can see where you're clicking.
💡
For maximum gaming performance, you can also enable the option “4x MSAA” in the “Hardware Acceleration” section, but this will lead to increased battery consumption and heat up the device.
Memory and background management
In the developer menu, you can find tools for managing RAM (RAM), the Application section contains a setting Limit of background processes, which allows you to strictly limit the number of applications that can work in the background.
The standard value is the Standard Limit. If you choose, for example, "No background processes," then when you fold an application, it will immediately be offloaded from memory. This can free up RAM, but it will cause messengers to stop receiving notifications instantly, and applications to load again every time they start.
Another important feature is not to turn off the screen. If you activate this switch, the smartphone screen will burn constantly while the device is charging, which is extremely convenient when developing or when the phone is used as a desktop clock or a monitoring panel.
There is also a window aggregation option that allows you to group notifications, but in modern versions of MIUI it is often duplicated by standard notification settings. The main thing here is not to overdo the memory limitations, since Android effectively manages resources itself.
💡
Changing the limit of background processes rarely gives an increase in performance in games, but can significantly worsen multitasking and messengers.
Frequent questions and problems with activation
Despite the simplicity of the procedure, users often face nuances, and the following are answers to the most popular questions that will help solve the difficulties encountered.
