Xiaomi Redmi Developer Mode: How to Enable and What the Hidden Menu Gives

Why the developer mode is hidden from users

Smartphone makers, including Xiaomi, deliberately hide the developer menu from ordinary users, not to complicate life, but to protect the system from accidental changes, because the parameters in this section directly affect the performance, security and stability of the device, for example, improperly configuring animations can lead to interface freezes, and changing the debugging settings over USB to security vulnerabilities.

However, Redmi’s developer mode offers unique features that will be useful for both advanced users and those who want to optimize the smartphone, including unlocking the bootloader (necessary for custom firmware installation), managing background processes (enables battery power savings), and even simulating a secondary display to debug applications. It’s important to understand that these features are not designed for everyday use, but in the right hands they turn the Xiaomi Redmi into a real sandbox for experimentation.

In this article, we will not only discuss how to activate the developer mode on different versions. MIUI, But what are the settings to touch first and which are best left alone? 10/11/12 and flagships of the K series, as they often have questions about the compatibility of functions.

Preparation of the smartphone: what to do before activation

Before you jump to the developer mode, make sure your Xiaomi Redmi is ready for the changes.

• 📱 Update. MIUI Some of the developer mode features may be missing or not working properly on legacy builds. → The phone. → Updating the system.
• 🔋 Battery charge of at least 50%. This is not a prerequisite for activating the menu, but if you plan to immediately test new settings (for example, Do not turn off the screen), it is better to be safe.
• 🔐 Remove the screen lock (if used) PIN/In rare cases, after a change in the developer's settings, the system may require a re-entry of the password.
• 📁 Back up important data. While the process of turning on the mode is safe, further experimentation with settings can lead to failures.

Special attention should be paid to users who have updated Redmi from MIUI Global to MIUI China or vice versa. In Chinese versions of the firmware, the path to the developer menu may differ, and some options (for example, Unlock OEM) may be blocked by default. If you are not sure about the version of your firmware, check it in Settings → About Phone → MIUI Version.

⚠️ Attention: On devices with MIUI For example, the Redmi Note 11 Pro+ 5G for the Russian market), some developer parameters may be limited due to local requirements of the legislation. USB and unlock the loader.

Step-by-step: how to turn on the developer mode on Xiaomi Redmi

The process of activating the hidden menu is the same for most Xiaomi Redmi models, but may vary slightly depending on the version of MIUI. We will consider a universal method that works on firmware from MIUI 12 to MIUI 14 (including HyperOS for new devices).

Follow these steps:

1. Open the settings on your smartphone.
2. Scroll down and select the About Phone section.
3. Find the MIUI version and tap it 7 times in a row, and after the first 3-4 clicks, a notification will appear like "You're almost there!"
4. After pressing 7, the system will display a message: "You became a developer!". This means that the menu has been successfully unlocked.
5. Return to the main Settings menu, and a new section will appear there — Additional → Developer Settings (or just Developer Settings in new versions of MIUI).

If nothing happens after 7 taps, check:

• 🔄 Did you get the version wrong? MIUI from the Android version (you need to click on the shell version).
• 📵 Make sure the screen is not locked during taps (such as a call or notification).
• 🔧 On some models (e.g. Redmi) K30 Pro) you may need to enter a password from your Mi Account after activation.

On HyperOS devices (such as the Redmi K70 or Redmi Note 13 Pro+), the path to the developer menu can look like this: Settings → About Phone → Version Information → Build Number. It also requires 7 clicks on the Build Number.

Top.-5 useful features in the developer menu for Xiaomi Redmi

Now that you've accessed the hidden settings, we'll see which ones are really useful in everyday use, and we've selected the 5 most useful options that don't require a deep technical knowledge, but can significantly improve the performance of a smartphone.

Important: On devices with a MediaTek processor (such as Redmi Note 10 or Redmi 9T), enabling the option to unlock OEM may require additional binding of the Mi Account through Settings → Xiaomi Account → Mi Unlock status. Without this, unlocking the bootloader will not be possible.

Another useful feature is Secondary Display Simulation, which allows you to test applications in multitasking mode or use your smartphone as a mini PC with an external monitor, but on Redmi with MIUI 13+, this option may not work as well due to manufacturer limitations.

💡

If after changing the developer's settings, the smartphone started to slow down, return the settings to factory values in the same menu. To do this, there is a button with three dots in the upper right corner → "Reset settings".

What to do if the developer mode disappears after the update

One of the common problems with Xiaomi Redmi owners is that the developer menu disappears after the MIUI update, which is because the system resets some hidden settings when you install the new firmware.

1. Repeat the activation procedure (7 taps on the MIUI version).
2. If the menu doesn't appear, check if it's hidden. To do this, open Settings. Type "Developer" in the search box. If the system finds Developer Settings but they're not displayed on the menu, they're just hidden.

On some devices (for example, Redmi K50 Gaming) after the update, you need to reset the cache of the Settings application:

Settings → Applications → Application Management → Settings (app) → Storage → Clear cache

If none of these methods worked, your Redmi model may have fallen under Xiaomi’s regional restrictions, such as on Indian-based devices (Redmi Note 11T 5G) after upgrading to MIUI 14, the developer menu may be blocked at the firmware level, in which case only a rollback to the previous version of MIUI or a global firmware installation will help.

⚠️ Note: Redmi with HyperOS (like Redmi Note 13 Pro) may disappear after resetting to the factory menus, even after re-activation, due to Xiaomi’s new security policy. ADB-Teams (root rights required).

Dangerous settings: what not to touch in the developer menu

Not all settings in developer mode are harmless, some of which can lead to loss of warranty, unstable operation, or even a "brick" (complete failure) of the device, and we have compiled a list of settings that we recommend not changing without a clear understanding of the consequences:

• 🚨 Allow downloads from unknown sources (ADB) — Opens access to the installation of applications through ADB, What could be used by attackers.
• 🚨 Turn off the absolute volume level on some models (Redmi) K40) This leads to distortion of the sound in Bluetooth headphones.
• 🚨 Turn it on. 4x MSAA — force GPU render graphics in 4 times higher resolution, which leads to overheating and battery discharge.
• 🚨 Change the size of the log buffer – an incorrect value can fill the system partition memory and cause crashes.
• 🚨 Insert the check GPU-Debugging – activates the debugging layer, which significantly reduces performance in games.

Redmi owners with Snapdragon processors (such as Redmi K50 or Redmi Note 12 Pro+) should be especially careful. Changing the parameters associated with the GPU or CPU can lead to trottling (automatic frequency reduction) or even chip damage during prolonged loads.

If you still changed the dangerous setting and the smartphone began to behave unstable, try:

1. Return the parameter to factory value.
2. Clear the system cache through Settings → Memory → Cleanup.
3. In extreme cases, perform a reset to factory settings (but this will delete all data!).

Developer mode on Xiaomi Redmi with custom firmware

If you use an informal firmware (like LineageOS, Pixel Experience, or crDroid), the process of activating developer mode may be different.

• 🔧 On most custom firmware, the developer menu is turned on the same way - after 7 clicks on the Assembly Number.
• 🔧 Some builds (like Havoc-OS) have an extended set of developer options, including setting up the color profile of the screen or controlling the clock speeds of the processor.
• 🔧 On firmware without GApps (Google Apps), options related to Google services (for example, Debugging Location) may not be available.

For example, if you manually change the Low Memory Killer (LMK) setting, it can lead to automatic reboots when memory is scarce, so always study the documentation for a particular firmware before experimenting.

For owners of Redmi with unlocked bootloader and custom firmware installed, the option of Root access in the developer menu will be useful.

• Manage superuser rights for applications.
• Mount system partitions in write mode (for example, to modify build.prop).
• Use applications like Titanium Backup or Greenify.

⚠️ Attention: On devices with MIUI, modified through Magisk (e.g. to obtain root rights), including some developer settings (e.g., Debugging by USB) This is due to Xiaomi’s security mechanisms that check the integrity of the system.
