+    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
