Samsung started shipping its Galaxy S8 and Galaxy S8+ phones in Korea, and some of the first customers are complaining that the display have a reddish tint - which did not go away even after correcting the color display settings. This issues was quickly labeled as "Red Gate"... will Samsung face a new crisis?
Samsung itself says that there are no quality issues - and that the problem can be adjusted. Customers are welcome to replace their device, though, at service centers in Korea.
Reporters from Korea speculate that the cause of this problem may be the new deep-red emitter adopted by Samsung in its latest AMOLEDs, or perhaps the Diamond Pixel pentile matrix.
It's obviously very hard to know what is going on - and this is pure speculation at this stage. I discussed this with Raymond Soneira from DisplayMate and he clarifies that his own two Galaxy S8 units are accurately calibrated and don't show any red tinting when everything is set to the Factory Defaults.
In the Galaxy S8 users can shift the white point to make the display more reddish or more bluish with the user color balance controls that are available under display settings. Raymond told OLED-info that he can reproduce the published photo that way.
Raymond says that Samsung indeed moved to a new deep-red emitter (which enabled them to increase the color Gamut) - but that deeper red does not change the white point. The pentil matrix is certainly not to blame, either. Raymond says that this problem could be caused by defective OLED panels, misadjusted displays - or software bugs. Or perhaps some setting is causing this (for example the night shift blue light filter is adjustable on the S8 which could be changed so the display has a reddish tint) which the consumers are not aware of.
The most likely issue, according to Raymond is the Color Balance controls. We'll wait to hear more news from Korea. One thing is clear, Samsung does not need another faulty flagship phone launch...
