Xiaomi Developer Mode: How to Enable in 30 Seconds and What It Gives

The developer mode on Xiaomi, Redmi and POCO smartphones is a hidden dashboard that gives you access to dozens of additional Android settings, which can speed up the interface animation, enable USB debugging for firmware, change network settings, or even emulate a different screen resolution, but by default, this mode is disabled — it needs to be activated manually through a hidden menu.

In this article, you will find the most current ways to enable developer mode for all modern versions of MIUI 14/15 and Android 13/14, including features for specific models (for example, Xiaomi 13 Pro or Redmi Note 12). We will also discuss which settings should be changed first and which should not be touched so as not to disrupt the stability of the system. If you plan to sew your phone, test apps or just want to make the most of your device, this guide is for you.

Why you need a developer mode on Xiaomi

Many users mistakenly think that the developer mode is only for programmers or those who are engaged in the firmware of smartphones, in fact, it is useful in everyday use.

• 🚀 UI speed: You can turn off or reduce the animation of transitions between screens, making the phone visually faster.
• 🔧 Debugging by USB: without this it is impossible to connect the smartphone to the computer for firmware via Fastboot or ADB.
• 📶 Network configuration: forced choice of network type (2G/3G/4G/5G), Enabling the recording of cellular events or even emulating another operator.
• 🖥️ Change screen resolution: useful for testing applications or if standard resolution seems too large.
• 🔋 Battery charge control: displaying the exact percentage of charge (even if it is hidden in the battery) MIUI) Limit charging to 80% to extend battery life.

But not all settings are secure, like changing Dalvik or ART settings can cause applications to crash, and setting up USB debugging incorrectly can cause security vulnerabilities, so before you change anything, you need to understand why.

⚠️ Note: On some Xiaomi models (e.g, POCO F5 or Redmi K60) When you turn on the developer mode, you may see a warning about an "uncertified device" in Google's settings, which is normal and does not affect the phone's performance, but may restrict access to some banking applications. USB after-use.

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

The activation process is the same for most Xiaomi smartphones, but there are nuances depending on the version of MIUI. Below is a universal method that works on Android 11/12/13/14 and MIUI 12/13/14/15.

Click on the Settings icon (cog)

Scroll down and select "About the phone"

Find the MIUI version and tap it 7 times in a row

Enter your password/pattern lock if you request it.

Return to the main menu "Settings" - a new item "For developers" will appear

-->

Let's take each step in more detail:

1. Open Settings (the gear icon on the home screen or in the application menu).
2. Scroll through the list to the About Phone section (on some models, such as the Xiaomi 12T, it may be called About the Device).
3. Find the line MIUI Version (usually the second or third on top) and tap it 7 times in a row, and after the first 3-4 clicks, a pop-up notification will appear, saying, "There are 4 steps left to become a developer."
4. At press 7, the system will request a password or pattern lock (if installed).
5. Now, a new item will appear in the main Settings menu, For Developers (sometimes it hides in the Additional section).

If the item for developers did not appear, check:

• 🔍 You've definitely been down the Version. MIUI, not on another line (e.g., the device model or the Android version).
• 🔄 Restart your phone – sometimes changes only apply after a reboot.
• 📱 Some firmware (e.g. global versions for Europe) may need to first enable Advanced Settings in the About Phone menu.

Alternative ways of inclusion (if the standard does not work)

On some devices (especially custom firmware or regional versions of MIUI), the standard method may not work, in which case, try one of the alternatives:

Method 1: Through the code of the engineering menu

Open the phone application and enter the combination:

##4636##

And then you're going to go to the engineering menu, and there's no direct access to the developer mode, but sometimes when you type in that code, you can activate the hidden settings, and if the menu doesn't open, your firmware is blocking that method.

Method 2: ADB (for advanced users)

If you already have access to ADB (for example, via a computer), you can enable the developer mode by the command:

adb shell settings put global development_settings_enabled 1

After completing the command, restart the phone – the item For developers should appear in the settings.

Method 3: For devices with locked settings

On some corporate or carrier versions of Xiaomi (e.g., from MegaFon or Beeline), access to hidden settings may be limited.

1. Install the update MIUI Up to the latest version (sometimes the restrictions are removed after the upgrade).
2. Use unofficial firmware (e.g. Xiaomi.eu), but this will void the warranty.
3. Contact the service center – they can unlock the settings on request.

⚠️ Note: On devices with a blocked bootloader (bootloader) some commands ADB To check the status of the bootloader, type in the terminal: fastboot oem device-info Search for Device unlocked: true/false. If false, the bootloader is blocked.

Top.-5 Useful settings in the developer mode

Now that the developer mode is activated, let’s figure out which settings should be changed first, and which ones should not be touched.

Important: The OEM Unlock setup allows you to unlock the bootloader, but when it is activated, you reset all the data on the phone, and only turn it on if you plan to flash the device.

What's better not to touch?

Some parameters can disrupt system stability or security, and this is not something you should change without a clear understanding.

• ⚠️ Disable the check MIUI — It can cause malfunctions in the shell.
• ⚠️ Background check – affects the operation of system processes.
• ⚠️ GPU-Acceleration – Incorrect settings can cause artifacts on the screen.
• ⚠️ Log buffer size – increases the load on memory.

💡

If you accidentally changed the setting and the phone started to glittle, try resetting the developer mode settings: go to Settings → Apps → All Apps → Settings, click Storage and select Clear Data.

How to turn off the developer mode

If you no longer need additional settings, you can deactivate the developer mode.

1. Go to Settings. → For developers.
2. In the upper right corner, press the switch (it should turn grey).
3. Confirm the action if a request appears.

After that, the Developer For option will disappear from the settings menu, and to activate it again, you will have to repeat the procedure with a 7-fold tap on the MIUI version.

If the switch is missing or inactive, try:

• 🔄 Reboot the phone.
• 📱 Reset the Settings app settings (as described in the previous block).
• 🔧 Update MIUI up to the latest version - sometimes bugs with a shutdown are fixed in new assemblies.

⚠️ Note: Some models (e.g. Xiaomi Mi) A3 or POCO X3 NFC With pure Android, the developer mode turns off automatically after the reboot, unless the settings have been changed.

Frequent problems and their solutions

Even after successful activation of the developer mode, users face difficulties, and here are the most common ones and ways to fix them:

Problem 1: The "Developers" item disappeared after the MIUI update

After major updates (e.g. from MIUI 13 to MIUI 14), the settings may be reset.

1. Repeat the activation procedure (7 taps according to the MIUI version).
2. If it doesn’t help, clear the Settings app data (as described above).

Problem 2: USB debugging doesn’t work

If the computer does not see the phone in debugging mode:

• 🔌 Check the cable – it should support data transfer (not all) USB-charging cables are suitable).
• 🖥️ Install Mi drivers PC suite ADB Drivers on the computer.
• 🔄 Switch the connection mode USB file transfer (MTP).
• 🔑 On the phone in the menu for developers find the configuration USB by default and select File Transfer.

Problem 3: The phone says "Device not certified"

This warning appears when you turn on USB debugging or OEM unlocking to remove it:

1. Turn off USB debugging in the developer settings.
2. Reboot the phone.
3. If the warning remains, check if custom firmware or modified cores are installed.

Security: What can and cannot be done in developer mode

Developer mode provides a lot of options, but it also gives you access to settings that can harm the device.

✅ What to do without risk:

• 🔧 Change the interface animation (transition speed).
• 📱 Include touch display (to record video from the screen).
• 🔋 Limit background processes to save battery.
• 📶 Forced to choose the type of network (2G/3G/4G/5G).

❌ What to do is not recommended:

• 🚫 Enable OEM unlocking without needing (this will reset all data).
• 🚫 Change the settings Dalvik/ART — It can break the app's work.
• 🚫 Disable the check MIUI — will cause malfunctions in the shell.
• 🚫 Demo Mode – It hides the real state of the battery and network.

If you're not sure what the setting is, you'd better leave it as the default, and most of the settings in developer mode are optimized by the manufacturer for stable operation.

💡

Developer mode does not void the warranty on the phone unless you have changed system files (for example, have not flashed custom recovery or received root rights).
