This is the same kind of stuff that I've seen on my logcats when I've had issues with the app launch hangs. InputDispatcher says that it delivers the touch input to some target, but then nothing happens. I'm not sure I've seen the 'pending(waiting finished signal)' message before.

Apparently, it should look something like this:

I/InputDispatcher( 158): Delivering touch to current input target: action: 1, channel '407a5218 StatusBar (server)'

or this

InputDispatcher: Delivering touch to current input target: x: 758.000000, y: 229.000000, action: 0x0, channel 'PointerMiniStatusBarView (server)', toolType: 0

It looks like the touch input is not being delivered to any server, activity, or target of any kind (i.e. null?). Thus no app opens or crashes because no app is launched or run at all.

Here's a report from the S3 that has an example of the "current input target:<null> action: 0x1" msg: http://xdaforums.com/showthread.php?p=28344195

Everything I'm finding on Google regarding this error is isolated to Samsung hardware (phones and tablets).
