For the record, my Note 4 isn't showing any burn in after > 1yr of use, but who knows what it will be like 4 years down the line.
A small number of users report burn-in on the newer s6/6p so I hope QC on the new Yogas will be tighter at the very least
I had burn-in on my old galaxy s4. Don't know or care if it's the "new" technology. The primary burn-in was noticeable due to Android's fixed top notification bar, as it almost never changed position or color. The times I would fire up a horizontal view or full screen app, the bar would obviously remain visible. I'm glad they wised up to iOS's approach and started blending the bar in with the app when possible.
From the parent: > New gen OLEDs like the one in Samsung S6 do not have any significant burn-in.
My point is that phones are not a good measure of the ability for an oled screen to be used on a laptop since phones have lower expected longevity.
