Introduction: Why you need a developer mode on Xiaomi
Xiaomi’s MIUI-based smartphones hide dozens of useful features from ordinary users — they can only be activated through developer mode. This is a special menu designed to test applications, debug the system and fine-tune the device. Without it, you can not unlock the bootloader, get root rights or change performance parameters.
Many people mistakenly think that the developer mode is only for programmers, but it's actually useful for ordinary users, because you can speed up the animation of the interface, turn on the user interface. USB-It's a debugging experience for PCs, changing the resolution of the screen, or even mimicking the second display, but the wrong settings can cause crashes, so it's important to understand what each setting is responsible for.
In this article, we’ll look at how to turn on developer mode on Redmi, POCO and other Xiaomi models, what features it opens up, and what risks it poses, and how to get it back if something goes wrong.
How to turn on the developer mode on Xiaomi: step-by-step instructions

- Find the MIUI version string and tap it 7 times in a row.
- After the seventh press, a notification will appear: “You became a developer!”
- Return to the main Settings menu – there will be a new section Additional → For developers.
If you have HyperOS, the path may be slightly different: Settings → About Phone → Device Information → HyperOS Version (also 7 taps). On some models (e.g. Redmi 10C), the Developer Section hides in Settings → System → Advanced Settings.
Check the MIUI/HyperOS version in the settings
Make sure your smartphone is at least 30% charged

The main functions of the developer mode: what can be configured
Xiaomi’s Developer Menu contains more than 50 options, but most of them are for testing, and we’ve highlighted the most useful features that ordinary users will need:
- 🔧 Debugging by USB — Allows you to connect your smartphone to a PC to work with ADB, installation of custom firmware or data recovery.
- ⚡ Accelerating animation – reducing window animation time (Windows Animation Scale, Transition Animation Scale) makes the interface faster.
- 📱 Simulating an additional display – useful for testing applications in multitasking mode.
- 🔒 OEM-Unlocking – a mandatory step before obtaining root rights or installation TWRP.
- 📶 Network Selection – Manual Switching Between 2G/3G/4G/5G (useful in areas with poor coverage).
- 🔄 Background processes – limiting the number of running applications to save battery.
You can also turn on Error Log (useful for crash diagnosis), change screen resolution (if supported by the device), or activate demo mode (hidden notifications in screenshots).
| Function | What do you need? | Risks. |
|---|---|---|
| USB debugging | Connection to PC, installation of software through ADB | Vulnerability to malicious attacks when connected to other devices |
| OEM-unlock | Unlocking the bootloader for custom firmware | Data reset, loss of warranty |
| Keep the screen down. | The screen remains on when charging. | Overheating, shortening battery life |
| GPU-acceleration | Forced use of GPUs for 2D rendering | Increased battery consumption, possible graphic artifacts |
⚠️ Warning: Changes in settings Minimum screen width or display size may cause interface failure. If after the changes the screen is not displayed correctly, return the values to the standard or reset the settings.

Dangerous settings: what not to touch without need
Some of the options on the developer menu can harm the device if you change them without understanding the consequences.
- ☠️ Not saving actions disables saving system logs, can lead to the inability to diagnose failures.
- ☠️ Forced Application Stop – can delete application data without recovery.
- ☠️ Turn off the absolute volume level - disrupts the operation of Bluetooth devices (headphones, speakers).
- ☠️ Strict mode - flashing screen when the processor boots.
- ☠️ Changing the size of the log buffer can cause memory overflow and slow down the system.
Critical error: Inactivity of the radio module turns off the mobile network, Wi-Fi and Bluetooth. You can only return to work through resetting.

Developer Mode and Security: How Not to Lose Data
Activating the developer mode opens up new possibilities, but it also creates vulnerabilities. USB-debugging allows the connected computer to access files, contacts and even passwords to minimize the risks:
- 🔐 Turn off the debugging. USB After use (in the Developer Menu) → Debugging by USB → Off.).
- 🚫 Do not connect your phone to public charging (BadUSB attack risk).
- 🔄 Update regularly MIUI — New versions close vulnerabilities associated with the developer mode.
- 📱 Use the lock screen (PIN, graphical).
If you plan to sell or transfer your phone, you must:
- Turn off the developer mode (as described above).
- Perform reset to factory settings (Settings → System → Resetting).

Developer mode on Xiaomi vs other brands: what is the difference
The functionality of the developer mode on Xiaomi is similar in many ways to Samsung, Google Pixel or Realme, but there are also unique features. MIUI possible:
- 🔄 Changing Network Priority (2G/3G/4G/5G) non-partisan.
- 📊 Include extended battery statistics (shows the flow rate for each process).
- 🎮 Activate Game Accelerator Mode (optimizes performance for games).
- 🔊 Set up separate sound profiles for SIM-Cards (useful for two sims).
At the same time, Samsung has a much easier access to Download Mode (similar to Fastboot), and the Google Pixel has built-in support for Android Flash Tool for firmware. Xiaomi’s main advantage is more flexible network settings and performance, but it comes at a cost of interface complexity.
The iPhone doesn’t have a developer mode analogue, instead using Xcode and Apple Configurator for professional tasks, and on Huawei (with EMUI), many of the developer’s functions are blocked without a special unlock code.
💡
Xiaomi’s developer mode offers more freedom than most Android devices, but it requires caution. Always check the setting before changing it!
