Budget smartphone owners often underestimate the potential of their devices, believing that advanced settings are only available in flagship models. However, Xiaomi Redmi 7A, which runs on the basis of the MIUI shell, hides a powerful toolkit for advanced users. Activating a hidden menu allows you to access functions that are hidden by default from the eyes of the average owner of the gadget.
The need to turn on developer mode can arise for various reasons, from the banal debugging of applications to fine-tuning the interface animation to speed up the system. In this article, we will discuss the activation process in detail, explain the assignment of key parameters and warn against typical errors that can lead to unstable operation of the device.
It's worth noting that tampering with system settings requires a certain amount of caution and understanding of the consequences. While the process of turning on the menu itself is safe, changing the settings inside it can affect the power consumption and stability of Android. Let's get to the step-by-step instructions.
Why you need to activate the hidden menu on MIUI
The main purpose of this partition in the operating system is to provide engineers and application developers with tools for testing, but over time, the functionality has expanded, and now ordinary users can use these features to optimize their Redmi 7A. For example, here is a USB debugging switch, without which you can not transfer files through ADB or use your smartphone as a modem to debug the network.
And this section also includes settings that affect the visual experience of the interface, you can change the scale of the fonts, the speed of animation of windows and transitions, which is especially true for devices with less powerful hardware, and speeding up animation creates the illusion of faster CPU operation, making the system response instantaneous.
⚠️ Attention: Change of the display scale settings (DPI) It can cause some interface elements to become unreadable or go beyond the screen.
Another important feature is the ability to back up passwords or manage application permissions at a deeper level. For device firmware enthusiasts, accessing this menu is a must-have first step before any software modification procedure.
Step-by-step instructions for the inclusion of the developer mode
The MIUI activation process is slightly different from pure Android, but it remains quite logical. All actions are performed through the standard settings application, which is preinstalled on every Xiaomi device.
The first thing you need to do is open the main settings menu on your smartphone, scroll down to the bottom of the list, where the phone and system sections are usually located, and that's where the key to the advanced features is hidden.
☑️ Activation algorithm
Find the item Version. MIUI (or MIUI This is the center line in the "About the Phone" section. To activate a hidden function, you need to quickly press this line seven times in a row. You don't need to pause between taps, the rhythm must be uniform.
After the fifth or sixth press, the system may ask you to enter the unlock password or the pattern lock, a security measure to prevent children from accidentally activating the mode, and after you enter the code, you will see a pop-up notification that the developer mode is activated.
⚠️ Warning: If nothing happens after seven taps, make sure you don't click too slowly.Try to make a series of clicks at a faster pace.
Where to find the developer menu after activation
Many users who have successfully clicked are lost because the new item does not appear on the main settings screen. Unlike some versions of Android, the layout logic has been changed in MIUI. You need to go back one level up in the main settings menu.
Look for the Additional settings section. It's inside this category, usually at the top of the list, that a new item called Developer's is going to appear, and now the hidden features are open all the time until you turn off the switch yourself.
| Parameter | Location on the menu | Function |
|---|---|---|
| USB debugging | Inside the developer menu | Allows the computer to control the phone |
| Window animation | Section Drawing | Application Opening Speed |
| Keep the screen down. | Main section | The screen burns while charging |
| Limit of background processes | Section of the Annex | Limiting the number of employees in the background of programs |
Inside this menu, you'll find dozens of different switches, and be careful, some of them may have a critical impact on how the system works, and it's recommended that you don't change the settings that you don't know what they're supposed to do.
Configuring debugging over USB and security
One of the most important features that most often turns on this mode is USB debugging, which allows your computer to communicate with your phone at a deep system level, and without this switch, many smartphone control programs on your PC won't see your device.
When the cable is first connected to a computer with debugging enabled, on the Redmi screen 7A You'll get a request for debugging permission. RSA-You need to tick "Always allow from this computer" and click "OK" so you don't get repeated notifications in the future.
It’s important to understand the risks: as long as USB debugging is enabled, any computer you connect your phone to will have wide access to the file system, so it’s not recommended to keep this feature active all the time unless you’re using it right now.
You can also find the default USB mode settings in this section, so you can set your phone up so that when you connect the cable, it immediately switches to file transfer mode, not just charging, which eliminates the need to switch modes in the notification curtain every time.
Optimizing performance through hidden settings
Redmi 7A owners often face the desire to speed up the interface, and the developer menu has a section called Drawing, where three parameters affect animation: “Window animation”, “Change animation” and “Duration of animation”.
By default, they're all set to "1x." Changing this to "0.5x" visually speeds up the opening of applications and the transition between desktops. The system starts to respond faster as the time for rendering graphical effects is reduced.
Another useful tool is to limit background processes, and if you notice that the phone starts to slow down when heavy games open, you can temporarily limit the number of background processes. However, on modern versions of Android, the system itself effectively manages memory, and manual intervention is rarely required.
There's also a "Don't Turn Off" feature, which if you activate it, the display of the smartphone will burn constantly while charging, which is convenient if you use the phone as a navigator in the car or as a desktop clock, but can cause the matrix to burn out over long periods of use.
Possible problems and ways to solve them
Despite the simplicity of the procedure, users may encounter a number of difficulties, such as the "Developers" item may disappear after a reboot if the "Developer Password" function in the MIUI security settings was activated, but you forgot it, in which case resetting the network settings or a complete reset of the device will help.
Sometimes the computer can't see the phone even when the debugging is on, and the problem is often the cable. USB-cables support data transmission; many cheap ones are designed solely for charging. Try replacing the cable with an original or quality one.
⚠️ Warning: Using damaged cables or substandard power supplies during debugging can lead to power surges, which is dangerous for the Redmi power controller 7A.
If you have changed the DPI settings (least width) and the interface is unreadable, don't panic. Try blindly to find the settings or plug in a Bluetooth mouse to get to the menu and return the default value. For Redmi 7A, the standard value is usually 360 or 392 dp.
