BugReport on Xiaomi: A Complete Guide to Creating a Mistake Report MIUI

Have you ever faced a situation where Xiaomi smartphone starts to slow down, applications crash for no reason, and the system behaves unpredictable? MIUI They ask users to submit a bugreport, a special report that contains detailed logs of the device, but what is it really about, how to create it correctly, and where to send it so that the problem can be solved?

Many owners of Redmi devices, POCO Or Mi have heard the term "bugreport," but not everyone understands what it means, and yet this tool is key to fixing system bugs, especially if the bug shows up after updating firmware or installing custom software. In this article, we will discuss what is bugreport, why Xiaomi needs it, and how to assemble it correctly – from a simple method through settings to an advanced method using the use of bugreport. ADB.

The important thing is, if you're not a techie, don't be intimidated by terms like "logs" or "state dump," we'll explain it in plain language and show you step-by-step instructions with pictures (where possible), and for power users, we've prepared advanced methods for collecting reports that will come in handy when working with custom firmware or modified devices.

What is bugreport and why is Xiaomi needed?

Bugreport (from bug - "error" and report - "report") is an automatically generated file containing detailed information about the state of the device at the time of failure.

• 📱 Logcat – Recording all OS events for the last period.
• 🔄 Dumpsys – a snapshot of current processes, services, and settings.
• 📊 Iron information: device model, firmware version, battery status, CPU load.
• 🛠️ Recent activity data: which applications worked, which commands were executed.

What is Xiaomi doing? It collects reports like this to:

1. Reproduce the error in the laboratory and find the cause.
2. Determine whether the problem is massive or isolated.
3. Test the fixes before releasing a new update MIUI.

Important: Without bugreport, developers often can’t diagnose the problem, especially if it’s deep-seated (like Android Runtime or hardware drivers) — for example, if your Redmi Note 12 suddenly reboots when you connect to Wi-Fi, the usual description (“I’m crashing”) won’t be enough — you need a full report.

⚠️ Warning: Don't confuse bugreport with a simple error screenshot or screen recording, which is superficial and doesn't help engineers address the root of the problem.

When to create a bugreport on Xiaomi

Not every little thing requires a report, but here are the typical cases where a bugreport is really needed:

• 🔁 Cyclical reboots (bootloop) after update MIUI.
• 🚫 System applications departures (e.g. com.android.systemui).
• 📵 Communication problems: network goes missing, doesn't work GPS Bluetooth.
• 🔋 Abnormal battery consumption (e.g. 2 hours of standby discharge).
• 🖥️ Artifacts on the screen or graphics failures (especially on devices with AMOLED-display).
• 🔊 Distortion of sound or complete absence of audio.

If the problem is a one-time problem (for example, one application fell once), just restart the device, but if the error repeats, it is time to collect the report.

Bugreport is also useful if you:

• 🛠️ Participate in beta testing MIUI And they found a critical bug.
• 🔧 Use custom firmware (like LineageOS or Pixel Experience) and are faced with incompatibility.
• 📦 Want to report the problem to the official forum Xiaomi or repository Xiaomi.EU.

How to create a bugreport on Xiaomi: 3 ways

There are several methods to generate an error report, depending on your level of training and situation:

Let us consider each method in detail.

Method 1: Create a bugreport through settings MIUI (simple)

How to Read Bugreport by Yourself (For Curious People)

If you want to go through the report yourself (for example, to find the root of the problem), here’s what to look for:

1.Fugreport file structure

The.zip archive contains several key files:

• bugreport-{device}-{date}.txt is the primary log.
• dumpsys/ — system service dumps.
• fs/ — filesystem.
• proc/ — process data.

The most important file is bugreport-*.txt. Open it with any text editor (e.g. Notepad).++ or VS Code).

2. Key sections for analysis

Look for the following blocks:

• 🔍 ===== SYSTEM LOG (logcat) ===== — Application logs and systems, and you can find errors like this. ANR (Application Not Responding or crash.

• 🔋 ===== DUMP OF SERVICE battery ===== — battery data (discharge, temperature.
• 🖥️ ===== DUMP OF SERVICE SurfaceFlinger ===== — information about the graphic stack (if there are artifacts on the screen).

An example of what a critical error in logs might look like:

04-10 12:34:56.789  1234  1234 E AndroidRuntime: FATAL EXCEPTION: main


Process: com.android.systemui, PID: 1234




java.lang.NullPointerException: Attempt to invoke virtual method on a null object reference




at com.android.systemui.statusbar.NotificationPanelView.updateNotifications(NotificationPanelView.java:1234)

This indicates NullPointerException in the system interface – a typical reason for System departures. UI.

3. Analysis tools

To simplify the analysis, use:

• 🔍 Android Studio Profiler – for visualizing logs.
• 📊 Gnirehtet – for remote viewing of logs in real time.
• 📂 Pidcat – a utility for filtering logcat.

Frequent Mistakes and How to Avoid Them

When you're working with bugreport, users often make mistakes that make the report useless.

• ❌ Create a report after the reboot, the logs are erased, and the problem becomes irreproducible.
• ❌ Delete files from archives. Developers need all the data, even if it seems unnecessary.
• ❌ Send a report without a description, and saying "I'm in a bad mood" won't help the diagnosis.
• ❌ Use old versions ADB. Update the platform-tools to the latest version.

Here's what we do:

• ✅ Reproducing the error immediately before creating the report.
• ✅ Specify the exact device model and version MIUI.
• ✅ Attach screenshots or videos (as an addition to the report).
• ✅ Check that the file is not empty (size should be) >5MB).

📌 An example of a correct description of the problem:

Model: Redmi Note 11 Pro+ 5G (veux)


MIUI version: Global 14.0.4.0.TKCMIXM




Problem: When connected to 5GHz Wi-Fi, the device restarts after 2-3 minutes.




Steps for reproduction:




1. Connect to a Wi-Fi network (802.11ac standard).




2. Start downloading a large file (>500 MB).




3. In 2-3 minutes, a rebuke occurs.
