Gathering Xiaomi Problem Logs: A Detailed User Guide

If your smartphone, TV, or other Xiaomi device malfunctions — spontaneously restarting, slowing down, or giving out errors — the first thing technical support will ask you to provide log files, which contain detailed technical information about how the system, applications, and hardware components work when the problem occurs, and without them, diagnosis often turns into guessing the cause at random.

Many users are struggling to collect logs: they don’t know where to look for the right settings, what types of magazines exist, and how to export them correctly. In this article, we’ll look at all the ways to collect problem logs on Xiaomi devices (including smartphones, Mi TVs, etc.). TV We will explain what data is recorded in logs, and give step-by-step instructions for different scenarios – from manual collection through the developer menu to automated tools like Mi Log Tool.

We’ll focus on critical bugs that can only be detected through logs, such as display drivers, Android kernel conflicts, or communication module failures, which are often ignored by standard diagnostics tools, but they help Xiaomi engineers release patches to fix bugs in the next firmware updates.

What are problem journals and why do they need them?

Problem logs are automatically generated files that record everything that happens on a device, from application launches to hardware component errors, and are divided into several types:

• 📱 System Logs – Android kernel events, drivers and services (e.g. logcat, dmesg).
• 🔧 Application Logs – errors and actions of specific programs (for example, Mi Home or Google Play Services crashes).
• 📡 Network Logs – data on Wi-Fi, Bluetooth, mobile network connections.
• 🔋 Power Logs – Information on charging, battery discharge and energy management.

Without this data, Xiaomi technical support will not be able to pinpoint the cause of the crash. For example, if your Redmi Note 12 suddenly turns off at 30% charge, the power logs will show whether the battery controller, firmware or physical wear of the battery is to blame. TV does not connect to Wi-Fi, network logs will indicate at what stage the connection breaks down – when authenticating or receiving IP-address.

⚠️ Note: Logs may contain sensitive information, such as the names of connected Wi-Fi networks, IMEI Delete any extra data before sending in support or use tools like Logcat Filter to clean up your device.

In most cases, the user doesn't have to understand the contents of the logs, just collect them correctly and pass them to the specialists, but by understanding what data is being captured, you can more accurately describe the problem in the circulation, which will speed up the solution.

When it is necessary to collect problem logs

Not every failure requires log analysis, for example, if Poco X5 I've been slow to run after installing a dozen games, the problem is probably a lack of RAM - here will help standard actions (cleaning the cache, removing unnecessary applications:

• 🔄 Cyclical Bootloop – The device turns on, shows the Mi logo and shuts off again.
• 📵 Communication problems: mobile network is lost, does not work Wi-Fi/Bluetooth, despite the correct settings.
• 🔥 Overheating for no apparent reason (e.g., Redmi) K60 heated up).
• 🎮 Artifacts on the screen: stripes, flickering, "broken" pixels that are not associated with physical damage to the display.
• 🔋 Incorrect battery operation: jumps in charge level, sudden shutdowns during 20-40%.

They will also ask if you are applying for warranty support or participating in firmware beta testing, such as before the stable version is released. MIUI 15 Xiaomi engineers analyze logs from beta testers to fix critical bugs.

⚠️ Note: If the device does not turn on at all (for example, after a failed update), collecting logs by standard methods is not possible. EDL-mode (emergency firmware) or diagnostics in the service center.

Some problems can be diagnosed without logs — for example, if the Mi Band 7 doesn't sync with your phone, check the Mi Fitness version and the resolution first, but if the basic diagnostics didn't work, the logs will be your main tool.

💡

If the problem occurs irregularly (e.g., once every few days), turn on log log logs in advance using the Mi Log Tool app so you don’t miss the moment of the crash.

Ways to collect magazines on Xiaomi smartphones

On smartphones under control MIUI There are several ways to collect problem logs, and the method you choose depends on the type of malfunction and your level of training:

Let’s look at each method in more detail.

Method 1: Standard report on the problem in MIUI

The easiest way, which does not require a PC connection, is suitable for most software failures:

1. Open the Settings. → The phone. → Report on the problem.
2. Select the type of problem (e.g., "App is not responding" or "System is unstable").
3. Please indicate the time when the failure occurred (if you remember).
4. Click Send report – the system will automatically collect logs for the last 10-15 minute.

The archive with the journals will be saved in the folder /MIUI/debug_log It can be sent to support or analyzed independently (for example, through the Log Viewer app from Google Play).

Turn on Developer Mode (7 times click on "Version" MIUI" on the telephone")

Make sure that the device has enough free space (minimum 500 MB)

Remember the exact time of the failure (for filtering logs)

Connect to Wi-Fi (if you plan to send a report right away)-->

Method 2: Use of the Mi Log Tool

The Mi Log Tool (available on Xiaomi's official website) allows you to collect advanced logs, including data on the operation of drivers and the kernel.

1. Download and install the Mi Log Tool on PC.
2. Connect your smartphone to your computer through USB (Turn on the debugging. USB developer-setting).
3. Run the utility and select the type of logs (e.g. Full Log for full collection).
4. Play the problem on your phone (for example, launch the app that crashes).
5. Click Stop in the utility - logs will be saved to the folder on the PC.

The advantage of this method is the ability to collect logs in the background without interrupting the device. F5 overheats during games, you can start logging before the game session starts and stop it after the problem appears.

Collecting magazines on Mi TVs TV and smart devices

On Mi TVs. TV And other Xiaomi smart devices, like Mi Router routers or Mi Smart Speaker speakers, have different log collection processes. There's no universal problem report menu, so you'll have to use alternative methods.

For Mi TVs, TV (Android TV)

If you don't. TV 4S or Mi TV Q2 It doesn’t work properly (for example, there’s no sound in certain apps or freeze screens), follow the following steps:

1. Go to Settings. → The device → On TV. → Android version TV.
2. Click on the line with version 7 times to activate the developer mode.
3. Back to Settings → The device → Developer settings and enable debugging by USB.
4. Connect the TV to the PC via USB-port and use ADB For collecting logs: adb logcat -d > miv_logs.txt

For convenience, you can use the Android utility TV Remote Control (available on Google Play) to control your TV from your phone while collecting logs.

For smart watches and fitness bracelets (Mi Band, Mi Watch)

On wearables, log collection is complicated by limited resources. If the Mi Band 8 doesn't sync or shows incorrect data, try:

1. Open the Mi Fitness app on your smartphone.
2. Go to Profile. → Settings → Report on the problem.
3. Select your device and describe the problem.
4. Click Send Logs – the system will collect data about the latest synchronizations and errors.

For a deeper diagnosis (for example, if the heart rate sensor is unstable), you may need to firmware through the Mi Fit Tool with the logging option enabled.

Journal Analysis: What to Look for in Logs

If you decide to understand the logs yourself, pay attention to the following error markers:

• 🚨 Critical failures (crash): lines with FATAL EXCEPTION, SEGFAULT or ANR (Application Not Responding).
• 🔌 Power problems: mention battery, charger or thermal (overheating).
• 📶 Network errors: WifiStateMachine, ConnectivityService or DHCP.
• 🖥️ Graphic artifacts: lines from SurfaceFlinger, GPU display.

Example of a Log Line Pointing to a Wi-Fi Problem: E/WifiStateMachine(1234): Failed to connect to network "MyWiFi" (status: 1)

Here status: 1 refers to an authentication error (incorrect password or incompatible type of encryption).

For easy analysis, use tools like Logcat Reader (Android) or Notepad.++ (PC) with a syntax highlighting plugin, filter logs by time, so it's easier to find the moment of failure.

💡

If you see a string of kernel panic or hardware fault in your logs, it indicates a hardware fault. In this case, self-repair is not recommended - contact the service center.

Frequent errors in journal collection and how to avoid them

Even experienced users sometimes make mistakes that make logs useless for diagnostics, and here are the most common ones:

• ⏳ Too short a write period: if the problem occurs once an hour and you collect logs in 5 minutes, the failure may not get into the file.
• 📱 Time mismatch: If the device is not set the date/time, logs will be sorted randomly.
• 🔌 Shutdown USB during collection: this will interrupt the recording and may damage the log file. USB 3.0 on PC.
• 🗑️ Remove old logs: some users are clearing folders /debug_log before collecting new data, but it can store valuable logs of past failures.

Another common mistake is ignoring context, for example, if you complain about Redmi 10's slow performance but don't point out that the problem only manifests itself when you connect to a particular Wi-Fi network, support professionals will look in the wrong direction.

• What applications were launched?
• Are peripheral devices (earphones, gamepad) connected?
• Did this happen after the update?

Where to send problem journals

Collected logs are useless unless analyzed, and this is where you can send the logs depending on the situation:

When sending in support of Xiaomi, be sure to specify:

• Device model (e.g. Xiaomi 13 Ultra, firmware version) MIUI 14.0.5).
• Time and conditions of the problem.
• Steps to reproduce the failure (if known).

The more you describe the situation, the faster you will get a solution.
