Taking logs for bug reports

These instructions will generate a logcat file which you can then attach to a [bug report]({{ "how-to/bugreport/#reporting-a-bug" | relative_url }}). That file basically consists of a log of system messages, including stack traces when the device throws an error, and debug messages from apps.

With a computer

{% capture content -%} This method requires that you have [adb installed]({{ site.baseurl }}/adb_fastboot_guide.html#installing-adb-and-fastboot). If you don't have it installed, please do that before continuing. {% endcapture -%}

{% include alerts/note.html content=content %}

1. Open Command Prompt (Windows) or Terminal (Linux/macOS).

2. Connect your device via cable or [over WiFi]({{ "how-to/adb-over-wifi/" | relative_url }}).

3. Type adb logcat -d > logcat.txt. This will save the log to logcat.txt.

   Additionally, the radio buffer can be viewed or stored with logcat. If needed or requested, type adb logcat -db radio > radio.txt to save it to radio.txt.
