I have 2 devices. The first one is Asus Eee Pad transformer with Android 4.1 onboard. When I connect it and debug using ddms log (in Eclipse) everything is OK: warnings are yellow, errors are red and so on. Also filters work fine.
But when I connect the new Samsung Galaxy S3 with Android 4.1.1 onboard logcat shows me some strange unformatted output. Here is a screenshot:
It seems that ddms treats all messages as warnings. I've updated all my development tools to the latest versions. It seems to be an OS bug.
