The leakage seems to even out over time into uniform "gray" (it did on my vita). And all recent Galaxy phones I've seen (from nexus onwards) have the same effect as vita display in dark.XOMTOR said:Not completely off but there was certainly no 'mura' effect, blotches or lines to be seen.
Should note that if you put say, an ipad screen next to them,lcd glow completely drowns the oleds leak, making it appear solid black.
