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.

- π‘ radio_log.txt β Mobile network and Wi-Fi data.
- π± events.log β user actions (clicks, application launches).
For analysis:
- Open up. main_log.txt in a text editor (for example, Notepad)++ or VS Code).

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:
- π Hardware malfunctions: If the power controller is burned or the screen is damaged, logs will not show a physical breakdown.
- π Locked bootloader: On devices with locked bootloader, some system logs may be empty.
- π΅ Complete reset: If the device does not turn on at all, it is impossible to collect logs (required) EDL-regime).
- π΅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, Widevineβs Netflix mistakes).
If the problem is related to:
- π Charging - check the cable and power supply.
- πΆ antenna Wi-Fi/4G β check the connectors.
- π Speakers β test the sound through headphones.
Logistics are unlikely to provide useful information.
