I've come to expect that from mine. Takes it about 2-3 seconds sometimes for the phone app to display on the screen where I can tap the accept button on the call. If I hold it sideways, even more time for it to figure out it needs to rotate the screen. On top of that, I use Skype calling as my main way to call..so more lag on the call in the initial 5-10 seconds. Dunno, I think sometimes the OS is trying to do way too much in the background. I constantly have to go kill the tracker process so it'll stop scanning and indexing my media.
