Whenever I'm updating or installing apps, if I turn my screen off or it times out it seems like the processes just stop until I turn the screen back on. This also happens when I'm updating my Listen subscriptions. If I do a manual refresh and new episodes start downloading but I turn my screen off it seems like they drop to a really low speed and sometimes they fail to completely download. This happens on both WiFi and cell data. I'm running 4.0.4 IMM30B. Any ideas what could be causing this?
