This screen shows logcat, kernel message and optionally xposed logs from Android operating system. Kernel messages and xposed logs require root. Logcat requires root or READ_LOGS permission.
You can configure actual log colors from settings.
You can filter the output by log level (info, warning, etc), or using a custom text. Alternatively to filtering you can search using a custom text.
You can also filter the output by killed or running apps.
Long-press a log to copy it to clipboard in case you want to use it in the terminal emulator.
Logs can be shared or saved to file for later reading/searching.
WARNING: Starting with Android 4.1, the app either needs root or READ_LOGS permission. I’m not autorized to provide any instructions for either of those (Play Store violation: Apps that provide instructions on how to hack services, software or hardware, or circumvent security protections).
