This is why your Galaxy S8 display may be tinting red, software update to the rescue
Some Galaxy S8 units have been showing red tint instead of the typical cold, blueish AMOLED colors
A Korean business publication has probed a few experts, as well as former Samsung employees, on the matter, and the opinions vary widely. One of the experts says that many screen batches experience problems like tinting or colored streaks on the display, including Apple's iPhones, but that it's especially true for phones like Notes and Galaxies, since "for OLED panels, it’s difficult to evenly deposit luminescent organic materials on panels, and this can cause discoloring."
Other experts attribute the possible reasons to a glitch in the voltage current that drives the red pixels way too high, or to crosstalk of the various subpixel colors that seeps into the reddish side of the spectrum. One former factory employee at Samsung has commented that it will be difficult to address the discoloration with a software update if it is a mishap during panel sheet production, though other experts counter that, depending on the issue, "a software update would be enough to balance out the reddish display to the extent that consumers are satisfied." In any case, these seem to be rather isolated incidents which can be attributed to the usual teething problems when a brand new technology like the tall and curved Infinity Display of the Galaxy S8 is produced in mass quantities, so we wouldn't lose too much sleep about it just yet. Unless we are the ones that happen to land a phone with a jolly reddish panel, that is.
