If you’re experiencing a HyperOS firmware bug, want to offer an improvement to MIUI, or need technical documentation to develop for Xiaomi’s ecosystem, it can be difficult to contact the company’s engineers directly. Unlike user support, developer feedback channels are scattered across platforms, often hidden behind registration or require English language skills. This article will collect all the relevant ways for 2026, from official forums to closed chats on Telegram, where firmware details and APIs are discussed.
It is important to understand the difference between technical support for users (which solves problems with warranty or settings) and channels for developers (where source code, drivers, undocumented features or bugs are discussed in beta versions of software). The former are responsible for 2-3 days and work in 10+ languages, the latter can ignore the requests of the week or require proof of your expertise. We will analyze how to increase the chances of response, what data you need to prepare for a bug report and where to look for informal communities of enthusiasts who sometimes solve problems faster than Xiaomi itself.
Xiaomi’s official channels for developers
The company provides several feedback platforms, but their structure often changes after rebrandings (for example, the transition from MIUI to HyperOS in 2023), below are the current resources, confirmed by the documentation of the Xiaomi Developer Program.
- 🌐 Official developer portal: devmi.com - here publish SDK, documentation API For smart devices and announcements of new integration opportunities, registration requires email confirmation and sometimes invitations (to access beta versions).
- 💬 Forum MIUI/HyperOS: new.c.mi.com — Developer section (available after selecting English language) where bug reports are accepted, but moderators often redirect them to internal tracking systems.
- 📧 Email for partners: developer@xiaomi.com — The address for companies developing applications for the Xiaomi ecosystem. 5-7 days, but only if the request concerns business integrations (e.g. adding support for your service to Mi Home).
- 🐙 GitHub repositories: Xiaomi puts some of the open source on GitHub (for example, the kernel for some devices or firmware utilities). Issues in these repositories are sometimes read by engineers, but activity is low - most queries remain unanswered.
⚠️ Warning: The new.c.mi.com forum is heavily moderated, and if you create a theme asking you to "fix a bug in the Redmi Note 12 camera" without logs or steps to play, it will be closed within an hour.
How to write a bug report for Xiaomi
Xiaomi engineers ignore 80% of the requests due to lack of data, and in order for your report to be considered, it must contain:
- The device model (exact, for example, 2304FPCDCG for the Redmi Note 12 Pro+ 5G, not just the "Redmi Note 12"). Find it in Settings → About Phone → Model.
- A firmware version (e.g. HyperOS 1.0.5.0.UMCCNXM) If this is a beta version, enter the build number (Settings → About phone → Build number).
- System logs can be accessed through the Mi Community app (Fedback section) or by command: adb logcat -d > xiaomi_log.txt Logs should cover the period before, during and after the occurrence of the bug.
- Steps to play (by item). Example: Open Camera. Switch to Pro mode. Press ISO → App crashed.
- Screenshots/video (if the bug is visual) Use the built-in Screen Recorder feature (without third-party apps) to record the screen.
⚠️ Note: If the bug is associated with unlocking the bootloader or custom firmware, it will not be accepted on official channels. For such cases, there are informal chats (see section below). Also, do not send logs containing personal data (phone numbers, authorization tokens) – this violates Xiaomi’s privacy policy.
☑️ Checklist before sending a bug report
Informal communities and chat rooms for developers
When official channels are silent, enthusiasts often find solutions on their own, and here are the verified sources discussing undocumented features, circumvention of constraints, and early firmware versions:
- 🤖 Telegram chat "Xiaomi" EU": @xiaomi_eu — They're posting custom firmware for the European region and discussing bugs. Chat administrators sometimes have connections to Xiaomi insiders.
- 💡 4PDA — Xiaomi" section: forum - Russian-speaking community with detailed guides on unlocking the bootloader, porting firmware and repair. @miui_su and @ingbrzy They are known for helping to finalize reports before sending them to Xiaomi.
- 🔧 GitHub-projects: XiaomiFirmwareUpdater - firmware archive and tools for their installation. mitool - utility for working with Xiaomi devices through ADB.
- 📡 Discord server "Xiaomi Devices": the invitation can be found through a search in Telegram at the request of Xiaomi Discord. Here they discuss the development under HyperOS and share insights about future updates.
⚠️ Note: In informal chat rooms, modified firmware (e.g. from Xiaomi.eu) is often distributed, and installation of these can result in a Mi Account or denial of warranty service.

How to speed up the response from Xiaomi: life hacks
Even a well-designed bug report can go on for months without a response, and this is what helps you get your attention.
| Method | Efficiency | Risks. |
|---|---|---|
| Twitter mentions @Xiaomi or @MIUIrom with #HyperOS hashtag | Medium (response if the bug is massive) | They can ban spam. |
| Posted on Reddit/r/Xiaomi with details | High (moderators sometimes pass posts to engineers) | Demands good English. |
| Sending a report via Mi Community in Chinese | Very high (Chinese users have priority) | You need to use a translator and VPN |
| Creating issues in GitHub repositories with bug tag | Low (but sometimes react) | They can close without explanation. |
💡 Useful tip: If the bug is critical (for example, the device does not turn on after the update), try contacting the regional representative of Xiaomi. mi.com/global/contact. In the letter, indicate that the problem interferes with the use of the device for its intended purpose - this will increase the chances of a quick response.
💡
The most reliable way to get an answer is to send a bug report in Chinese through the official Mi Community app (available only on the Chinese App Store).
Connecting with Smart Device Developers (IoT)
If your question is not about a smartphone, but about Mi Home devices (robot vacuum cleaners, lamps, sensors), the communication algorithm is different.
- 🏠 Mi Home App: Bugs and suggestions for the app are sent through Settings → Feedback in the app itself. Answers are rare, but data is shared with developers.
- 🤖 Smart devices: there's a separate channel for each gadget. For example, for robot vacuum cleaners, email mirobot.@xiaomi.com, lamp-lamp@xiaomi.com. A complete list of addresses can be found in the documentation for the device.
- 🔌 Open IoT Platform: If you are developing integration with Xiaomi IoT, sign up at iot.mi.com. API-documentation and feedback form for partners.
⚠️ Note: For Xiaomi devices sold under other brands (such as Roborock or Huami), contact the relevant company. Even if the gadget works through the Mi Home, its firmware can be developed by third-party teams.
Frequent mistakes when contacting Xiaomi
Many users get rejected or ignored because of typical miscalculations.
- 🚫 Write in Russian in international forums. Use English or Chinese (via translator).
- 🚫 Send logs without description, and the phrase "I'm on a phone, here's the log" will be ignored.
- 🚫 Asking for help unlocking the bootloader on official channels.This violates Xiaomi's rules.
- 🚫 Spam in several forum topics, you'll be banned for flooding.
- 🚫 Threaten or insult in your appeals, even if the bug is critical, be polite.
💡 Useful advice: If you are not sure that your report is correct, first publish it on the website. 4PDA or in a Telegram chat - experienced users will tell you what you need to improve.
