I've noticed a few times when I turn the screen on, if I had it on wifi, that the wifi was off and it was on 4g. Then the wifi will immediately come back on. And yes I do have it set to "always" keep wifi on during sleep. So I don't know if this is a bug or what. Doesn't seem to affect battery life that much, and the wifi coming back on is immediate. But sometimes it does this and sometimes it doesn't.
Anyone else having this issue? Or know a fix? (Besides trying a custom ROM...I'm trying to hold out until they fix the shutter delay issue with the 4.0.3 ROMs)
For the record I am rooted, but I am running completely stock 4.0.2
