A major advantage of using Developer options is that the selection will be persisted over reboots, but the disadvantage is that you cannot set each buffer individually. I have found that when switching to off, logcat will still hold and report a buffer size of 64Kb.

This will display options ranging from off to 16Mb. Then navigate to the newly visible Developer options entry, scroll down, and click on logger buffer size. First enable Developer options in Settings. Via the UIĪs of Android 5.0, there’s also way to change the buffer size via Developer options on the device. Alternatively, you can use Terminal Emulator with command “ logcat > /sdcard/log.Something to be aware of when using this method is that the settings will not be persisted over reboots, so you will have to send this command on connection to ensure the buffers are set at the sizes you expect. You can either download the SDK and use adb logcat or get Logcat Extrem from the Google Play Store, which shows the log directly on your phone.
