I thought OLED burn-in was something I'd have to just deal with down the road when I bought a Samsung Galaxy Tab Pro S (windows tablet), and that the machine was going to be on a two year countdown before becoming annoying.

So far it's been about 30 months with, no issue. I've taken no active steps to fight against burn-in, but also haven't completely disabled the default screensaver (a wobbling word art thing that displays the name of the tablet model after about 5 minutes of disuse). I've been checking for burn-in periodically as I'm suffering from a bit of upgrade-itus, and that would be a fantastic excuse.
