Taking logs for bug reports

These instructions will generate a logcat file which you can then attach to a bug report. 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

Note: This method requires that you have adb installed. If you don’t have it installed, please do that before continuing.

Open Command Prompt (Windows) or Terminal (Linux/macOS).
Connect your device via cable or over WiFi
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.

On your device

Note: This method requires that your device is rooted.

Install and open some Terminal app, we recomend that: https://play.google.com/store/apps/details?id=yarolegovich.materialterminal
Type su and confirm root access - you may have to turn on root access for apps in Developer options.
Type logcat -d -f /sdcard/logcat.txt. This will save the log to /sdcard/logcat.txt.

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