Sporadic issue with the display not going to sleep while a podcast is playing. This is something that keeps rearing it's head over several version updates. Seems to work for a time then, without explanation, occurs again. The old trick found by another forum member where clearing out the phones recently used apps in the overview seems to fix this problem. Again, it's sporadic and I don't see a pattern why it won't go to sleep one time, then successfully works the next.
