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

Xiaomi’s hidden capabilities are both a treasure trove for power users and a potential threat to newcomers. Developer Mode provides access to dozens of options that the manufacturer hides “for safety.” But how do you activate it on the Redmi Note 12, POCO X5 or Black Shark 5 in 2026?

This article will not only explain how to turn on developer mode on Xiaomi, but also explain what features are becoming available, how to use them correctly, and why some settings can lead to loss of warranty or “bricking” of the device. We will deal with debugging over USB, unlocking OEM, changing animations and other “chips” that are hidden from ordinary users.

What is a developer mode and why it is needed

Developer Options is a hidden menu in MIUI designed to test and debug applications, and it includes more than 50 parameters that allow you to:

• 🔧 Speed up animations – reduce the time of transitions between screens.
• 📱 Emulate other devices – change screen resolution or pixel density (DPI).
• 🔌 Turn on the debugging. USB — necessary for the operation of ADB, Firmware via Fastboot or using XiaomiTool.
• 🔒 Unlock the bootloader is the first step to install custom firmware (LineageOS, Pixel Experience).
• 📊 Display process information – useful for diagnosing lags and battery consumption.

But not all functions are equally useful. GPU-rendering can lead to graphic artifacts, and Force activation 4x MSAA — So, before you change any parameter, you have to understand what it's responsible for.

⚠️ Attention: Some settings (for example, OEM Unlocking) resets to factory settings after reset. If you plan to unlock the bootloader, turn on this option in advance, otherwise you will have to wait 7 days after resetting.

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

The activation process is the same for all devices on MIUI 12/13/14, including Redmi, POCO and Black Shark.

1. Go to Settings → The phone.
2. Find the MIUI version and tap it 7 times in a row.
3. After the notification “You became a developer!” return to the main settings menu.
4. Now in the Settings → section, a new item will appear additionally – For developers.

If the MIUI version is missing (e.g., on some versions of POCO Launcher), try:

• 🔍 Go to Settings. → System system → About the device → Device information.
• 📱 On some models (Black Shark) you need to tap on the Assembly Number.

Some firmware (e.g. MIUI Global Stable for Redmi 9A) may request a password from your Mi Account after tap 7. This is normal – enter the data to confirm the rights.

Where is the developer menu after activation?

Once the developer mode is successfully enabled, you still need to find it, and depending on the version of MIUI, the path may differ:

If the menu suddenly disappeared after the MIUI update, try:

1. Reset the device.
2. Repeat the tap procedure according to the MIUI version.
3. Clear the Settings app cache (Settings → Applications → Application Management → Settings → Storage → Clear the cache).

The most useful features of the developer mode on Xiaomi

Not all options on the developer menu are equally useful, but we have selected the TOP-5 features that will be useful to most users:

• ⚡ Debugging by USB (USB Debugging – mandatory for working with ADB, Firmware via Fastboot or using XiaomiTool V2.
• 🔓 Unlocking OEM (OEM Unlocking: Unlocking allows you to unlock the bootloader to install custom firmware.
• ⏱️ Accelerate animations – install window animation = 0.5x, Animation of transitions = 0.5x, Duration of the animator = 0.5x speed up the interface.
• 📱 Show layout bounds – shows the boundaries of interface elements (useful for designers).
• 🔋 Background process limit – limit to 2 processes to save battery life (but some applications may close more often).

Be wary of settings related to GPU and Hardware Acceleration, for example, enabling Force GPU Rendering can lead to:

• 🔥 Processor overheating.
• 🖼️ Artifacts while watching videos.
• 🔋 Accelerated battery discharge.

💡

If after changing the settings of the GPU, the screen began to “glutch”, restart the device in Safe Mode (press the power button → “Reboot in Safe Mode”) and reset the developer settings.

Dangerous settings: what not to touch without need

Some of the options on the developer menu can permanently disable a device or make it vulnerable to attacks. We've identified the 3 most risky options:

1. Disable HW overlays (Use of the GPU for 2D-rendering) – can lead to graphical failures and “flights” of the interface.
2. Force RTL layout (Compulsory layout) RTL-layout) – mirrors the interface, breaks many applications.
3. Stay awake (Do not turn off the screen when charging) - the risk of overheating and degradation of the battery.

⚠️ Attention: Enable Bluetooth setup HCI sniffer logs records all Bluetooth packets in plain view. If you connect to public networks (such as a cafe or airport), attackers can intercept your data.

Also, avoid changing the parameters:

• 📡 Mobile data is always active – increases traffic consumption in the background.
• 🔊 Disable Absolute Volume – Can Break Volume Control in Bluetooth Headphones.
• 🔄 Aggressive data handover – leads to frequent switching between Wi-Fi and mobile network.

How to turn off the developer mode on Xiaomi

If you no longer need the hidden settings, you can deactivate them.

Frequent problems and their solutions

Even after activating the developer mode correctly, users encounter errors, and we have compiled the TOP-3 problems and ways to solve them:

If you see the message “We have to wait 168 hours” after OEM Unlocking is enabled, that’s OK. Xiaomi blocks the bootloader from unlocking for 7 days to protect against theft. You can’t get around this restriction — you have to wait.
