Modern smartphones, especially those running MIUI shells, hold huge potential for advanced users. Xiaomi’s Redmi 9C owner often faces a desire to optimize the device, speed up interface animations, or connect the gadget to a computer for deep debugging. The standard settings menu does not provide access to all the necessary features that the company’s engineers have hidden in a special section.
Activating this hidden partition gives you access to dozens of parameters that affect the behavior of the Android operating system. This is not just a technical option for programmers, but also a useful tool for the average user who wants to make the smartphone more responsive. In this article, we will discuss in detail the process of activating and configuring hidden functions.
Many users are afraid to get into system settings, considering it dangerous. However, if you act carefully and understand the purpose of each option, you can significantly improve the user experience. 9C worked as efficiently as possible.
Why activate the hidden menu on Redmi 9C
The main purpose of hiding these settings is to protect inexperienced users from accidentally changing critical system parameters, but for enthusiasts, this is a real gold mine.
One of the most popular features is changing the speed of the animation of the windows. Standard values in MIUI often seem to be delayed, creating the illusion of slow processor. By changing the scale of the animation, you visually speed up the response of the Xiaomi interface without losing performance.
This feature is also indispensable when connecting a smartphone to a PC to transfer files in specific modes or when using tools like ADB. Without activating this option, the computer can only see the phone as a drive or power source.
It is worth noting that some games and applications may require a forced change in screen resolution or DPI to display correctly, all of which are made available only after a specific sequence of actions is performed, which will be discussed below.
Step-by-step activation instructions
The process of enabling hidden features on the Redmi 9C is as simple as possible for developers, but it requires care. You don't need to download third-party apps or have root rights. Everything is done with the regular tools of the system.
The first thing you need to do is open the main settings menu of your device. Usually the icon is a gear and is located on the desktop or in the folder with system utilities. Find the item About the phone, which is most often at the top of the list or in the section Advanced settings depending on the version of MIUI.
☑️ Activation algorithm
The key is to find the line MIUI Version, which you click on several times in a row, and the system will count your clicks and display pop-up notifications about how much is left before activation. It usually takes 7 quick clicks.
⚠️ Note: If a password is installed on the device, PIN-A code or pattern lock, the system will require you to enter it after the seventh press, a security measure that prevents unauthorized persons from accidentally activating it.
Once you have successfully entered your password, you will see a pop-up message saying, "You've become a developer!". From that point on, a new section will appear in the settings menu, which we will discuss in the next paragraph. Don't worry if you can't press the right number of times the first time, just start again.
Where to find the developer menu that appears
Once activated successfully, the new section doesn't appear on the home settings screen as many would expect; it's hidden in the back of the menu to keep users from horny. On the Xiaomi Redmi 9C, the path to it is as follows.
You need to go back to the main settings menu and scroll down to the Additional Settings section. In some firmware versions, this item may simply be called Advanced Settings. Inside this section, usually at the bottom of the list, the item you want will be looking for.
The name of the item may vary depending on the localization of the system, and in the Russian version it is most often indicated as For developers. If you have an English localization, look for the Additional settings line, and then Developer options.
What to do if the menu does not appear?
Inside this section, you'll find a long list of parameters, grouped by category, and you'll find debugging settings, network settings, graphics, and memory, and be careful when you change values without knowing their exact purpose.
The main settings for optimizing the Redmi 9C
Once inside, you see a lot of things, and first, you should look at the ones that actually improve your everyday use of your smartphone, and first of all, the speed of the interface.
Find a section that's about drawing or animation, and there's three things: window animation scale, transition animation scale, and animation duration. They're 1x by default. Changing that value to 0.5x makes the interface livelier and faster.
Another important factor is the limitation of background processes, and if your Redmi 9C starts to slow down because of the large number of open applications, you can limit the number of applications, but don't put the limit too tight, otherwise messengers will stop arriving on time.
| Parameter | Recommended value | The effect |
|---|---|---|
| Scale of animation | 0.5x | Visual acceleration of the interface |
| Background processes | No more than 4. | Savings in RAM |
| Hardware acceleration | Included. | Smooth graphics in games |
| USB debugging | Off. | Security of data |
Also worth mentioning is the Forced Full Screen feature, which allows you to run old apps that aren't optimized for today's elongated screens in the right format without black bars on the sides.
💡
Tip: Before you change any parameters, take a screenshot of the initial values, which will help you quickly return everything to the same way as before, if the system begins to behave unstable.
Functions of debugging and connection to the PC
For advanced users who are engaged in firmware or deep system setup, the key is the Debugging over USB. This feature allows the computer to send commands to the phone, install applications directly and access system logs.
When you first turn on this option, the system will issue a serious security risk warning, which you only need to confirm if you connect the device to a trusted computer, otherwise an attacker can access your data through a secure security system. USB-cable.
In addition, you can select the default USB mode in this section, so you can set your phone to go straight to file transfer mode (MTP) when you connect to your PC, bypassing Charge Only, saving time with frequent document handling.
⚠️ Warning: Do not leave the debugging on USB It's permanently turned on if you use public charging stations frequently, and it can be a vulnerability to your personal data.
Another useful option is the choice of configuration USB. Here you can emulate different devices, for example, make the phone to be defined as MIDI-tool (RNDIS), What is useful for distributing the Internet through cable.
Possible problems and solutions
Xiaomi users may face a number of challenges in setting up, and sometimes the developer menu will spontaneously disappear after a reboot, and this is not a bug, but a feature of MIUI protection, in which case the activation procedure will have to be repeated after seven clicks.
Another common problem is that you can't change some parameters, they're gray, which means that the current state of the system or the application that's running is blocking the change. Try closing all the background programs.
If the phone starts to behave incorrectly after changing the settings (sound disappears, sensor does not work), don’t panic. At the top of the developer menu, there is a switch that turns off all the changes made with one touch, returning the system to the factory parameters of this partition.
💡
The bottom line: The developer menu is a powerful tool, but it requires caution, and only change the settings that you understand.
It is also worth considering that some carriers or custom firmware may block access to certain network functions in this menu, in which case only resetting network settings or flashing the device to the global version will help.
