I haven't been able to reproduce it, but it was on my iPhone 4, iOS 5. I'm curious if anyone else has seen this.
While using my phone (I was typing an iMessage) my phone went very dim like it does just before it locks, even though I was using it. I continued using it for a minute or two and it never came back to full brightness. I did a lock/unlock cycle and it was fine.
