That's the only real bug I'd noticed as well. Sometimes I suspend the phone with the keyboard open if I'm in the midst of a text conversation and want to preserve battery. The keyboard says lit. If you then close the phone it wakes it back up and it didn't used to.
Nothing that's a deal breaker, I'm just happy having the keyboard stay lit since I frequently do text in the dark. God forbid I pause for thought longer than 6 seconds and have the keys go black on me.
