Why Xiaomi Needs System Logs

If you've ever encountered a technical problem on a Xiaomi smartphone, TV or smart device, you've probably heard the advice, "Get logs and send them to support." But what are those logs, where they're stored and how to get them? Here comes Log Generator, a built-in diagnostic information collection tool.

This feature is present in almost all Xiaomi devices based on Android or MIUI, But not everyone knows it exists, and Log Generator logs contain data on CPUs, memory, network connections, application errors, and even hardware failures, all the data you need to accurately diagnose the problem. Without them, the support service often refuses to consider the appeal, citing a lack of information.

In this article, we will go into detail about what Log Generator is, how to activate it on different Xiaomi devices, where to look for collected files and how to interpret them correctly, and why logs can sometimes not be saved and what to do about it.

Log Generator (or "Log Generator") is a system application in firmware MIUI, HyperOS and some versions of Android TV It's on Xiaomi devices, which collects detailed reports on how the system works:

  • πŸ“± Device information: model, firmware version, serial number, processor and memory data.
  • πŸ”„ Logs: on/off time, errors at system start.
  • πŸ“‘ Network activity: Wi-Fi, Bluetooth, mobile Internet logs.
  • ⚠️ Application errors: crashes, freezes, forced close (forced closures).

How to properly collect logs on Xiaomi

Just clicking on the Log Generator is not enough, you need to know how to reproduce the problem and what settings to choose.

Activate Developer Mode (if required)

Open Log Generator and select the type of logs

Replay the problem (for example, run an application that crashes)

Save the file in a convenient place-->

Step 1: Selecting the type of logs

Log Generator usually has several options:

  • πŸ“„ Basic Logs – Minimum information (suitable for minor bugs).
  • πŸ” Advanced Logs – a complete system dump (needed for serious failures).
  • πŸ“± Application Logs – Only Errors of a Specific Software.

For most cases, choose Extended Logs.

Step 2: Reproducing the problem

Logs record events in real time, so:

  1. Start Log Generator and click Start recording.
  2. Play the bug (for example, try to connect to Wi-Fi if there is a problem with the network).

After collection:

  • The file will be saved in the folder. MIUI/debug_log (for smartphones or Download (for TVs).
  • The file name usually begins with log_ or bugreport_.
  • Archive the file (e.g., in.zip) before sending it to support, which will speed up the download.

πŸ’‘

If logs are not saved, check the free space on the device (needs at least 500 MB) and repeat the process. On some firmware, rebooting helps before collecting logs.

What to do if the Log Generator is not working

Sometimes users find that Log Generator doesn't start, doesn't save files, or gives out an error, and here are the typical problems and solutions.

If none of the methods worked, try alternative ways to collect logs:

  • πŸ€– Through ADB: Connect the device to the PC and execute the command: adb bugreport File bugreport.zip will remain on the computer.
  • πŸ“± Loglogger applications: MatLog, Logcat Extreme (require root rights for full access).

In the command line, type: adb devices (should display your device). 4. Follow the command: adb bugreport bugreport.zip 5. File. bugreport.zip It will appear in the folder with platform-tools.

⚠️ Note: On Xiaomi TVs collecting logs through ADB You may need additional drivers. Use the official Mi utility. TV ADB Tool to simplify the process.

How to Read and Analyze Xiaomi Logs

Log files from Log Generator are usually archives with the.zip or.tar.gz extension. Once unpacked, you will see many files with the.txt,.log or.dmesg extensions.

  • πŸ“œ main_log.txt β€” log-book.
  • πŸ”§ dmesg.log – kernel logs (hardware errors, drivers).
  • πŸ“‘ radio_log.txt β€” Mobile network and Wi-Fi data.
  • πŸ“± events.log – user actions (clicks, application launches).

For analysis:

  1. Open up. main_log.txt in a text editor (for example, Notepad)++ or VS Code).
  2. Look for strings with keywords: ERROR β€” fault-break. CRASH β€” drop-off. FAILED β€” opportunism. EXCEPTION β€” exceptions.

Pay attention to time stamps – they will help you to match the error with your actions.

Example of a log fragment with a Wi-Fi error:

05-20 14:30:45.123 E/WifiStateMachine(1234): Failed to connect to network "MyWiFi" (SSID="MyWiFi"), reason: AUTHENTICATION_ERROR


05-20 14:30:45.125 E/WifiConfigManager(1234): Unable to associate with MyWiFi, security type: WPA2-PSK

You can see here that the problem is authentication (AUTHENTICATION_ERROR), It may be an incorrect password or an incompatible type of security.

If you don’t know about logs, don’t try to β€œfix” the device yourself for the errors you find. Send files to support Xiaomi with a description of the problem – experts will give accurate recommendations.

When Logs Cannot Help: Log Generator Limits

While Log Generator is a powerful tool, it is not all-powerful, and there are situations where logs are useless or even misleading:

  • πŸ”‹ Hardware malfunctions: If the power controller is burned or the screen is damaged, logs will not show a physical breakdown.
  • πŸ”’ Locked bootloader: On devices with locked bootloader, some system logs may be empty.
  • πŸ“΅ Complete reset: If the device does not turn on at all, it is impossible to collect logs (required) EDL-regime).
  • πŸ•΅οΈ Firmware problems: If the system is damaged (for example, after a failed update), logs may be incomplete.

It is also worth considering:

  • Logs do not show what the user clicked (for example, which password was entered).
  • They do not have data on the actions in some applications (for example, banking).
  • Xiaomi Logistics does not contain information about DRM (For example, Widevine’s Netflix mistakes).

If the problem is related to:

  • πŸ”Œ Charging - check the cable and power supply.
  • πŸ“Ά antenna Wi-Fi/4G β€” check the connectors.
  • πŸ”Š Speakers – test the sound through headphones.

Logistics are unlikely to provide useful information.

FAQ: Frequent questions about Log Generator in Xiaomi

πŸ” Can I collect logs without a developer mode?
On most devices, it is not, as Log Generator is hidden in the developer menu. Exception: some Xiaomi TVs allow you to export basic logs through standard network settings (Settings) β†’ Network β†’ You can also use applications like MatLog, but they require additional permissions.
πŸ“± Where Logistics Are Stored After Collection?
The path depends on the device: Smartphones: /sdcard/MIUI/debug_log/ or /sdcard/Download/. Televisions: /storage/emulated/0/Download/. Routers: Logs are only available through the web interface (192.168.31.1). Files usually weigh from 5 before 50 MB (extended logs can reach the 100+ MB).
⏳ How long does it take to collect the logs?
30 seconds to 5 minutes, depending on: Type of logs (basic or advanced), device performance (on weak smartphones longer), data volume (the more errors, the longer the processing takes), do not interrupt the process, otherwise the file may be corrupted.
πŸ”’ Can you fake the logs?
Technically, yes, but it doesn't make sense. Logs contain unique timestamps, device identifiers, and checksums. Xiaomi support will easily detect forgery on data inconsistencies (e.g., if the time of an event does not coincide with the time zone of the device), and falsifying logs can lead to denial of warranty service.
πŸ“€ Where to send collected logs?
Official channels: Through the feedback form on support.xiaomi.com. To the chat with support in the Mi Community app. To the Xiaomi forums (for example, c.mi.com), if the problem is massive. When sending, specify: Device model. Firmware version (Settings) β†’ Detailed description of the problem (when it occurred, how it manifests itself).
