This might seem like a dumb question if this is how the phone is designed to work, but when I'm using the phone, and the screen is on, the answer/caller id screen stays on the entire time the phone is ringing (as I would definitely expect). However when the phone is locked, the slide to answer/caller id screen goes blank after 2 rings, but the phone continues to ring the final 3 rings (my ringtone is 'Old Phone'). So the only way to see who is calling or answer the phone if I don't get to it by the second ring, when the phone is locked, is to click the home button. So if that is how it is, then I suppose its just a minor annoyance, but if there is an option to change it, or if my phone isn't correctly handling incoming calls, I would appreciate finding that out.
