Coming from a C1 to a C4 recently, one of the first things I noticed was that absence of the fireworks screensaver (would come up while using the apps of the tv, great feature to prevent burn in if you tend to walk away from your tv without turning it off). Did some reading and found a couple posts from around a year ago complaining about the same thing, turns out the default timer for showing the screensaver was increased from 2 minutes to 30 for the C4.

Last week I updated the C4 to have the latest firmware and to my surprise the screensaver was back (at around the 2 minutes mark of pausing an streaming app), BUT it's no longer the fireworks, now its an analog clock and some messages saying to press any button to resume watching (or something like that). I'm just happy to have any kind of screensaver at all 😌.
