Records various log types and compresses them as a zip file.
The logs are saved in the application's private cache directory
named by the date and time.

You can access the zip files through the system document picker

Select the SysLog app to view collected log zips.

Log types supported:

Kernel logs (dmsg)
Last kernel log (last_kmsg, if device supports it)
Main log (Logcat)
Modem log
Event logs
SELinux audit logs

To enable access to some logs (Logcat and Radio) to SysLog, you
will need to grant the READ_LOGS permision using a computer with
ADB.

From a command line with adb available, you can grant the READ_LOGS
permission via the following command:

adb shell pm grant com.tortel.syslog android.permission.READ_LOGS

This command tells the phone's package manager to grant the
READ_LOGS permission to SysLog.
