Early Galaxy S8 Adopters Complain Of Red-Tinted Super AMOLED Displays
Liquid-crystal display (LCD) smartphone panels use three subpixels per pixel in red, green, and blue. AMOLED displays have a PenTile arrangement of two subpixels in red-green and blue-green. These displays need more than two pixels in order to produce a full range of color. This necessity, however, can muck with a device’s color balance. Many customers complained that the Galaxy Note 7 also had a red-tinted display.
There is currently a debate over the cause of the reddish-hue and the proper actions to eliminate it. Some experts insist that the color variation is due to a chip in the phone that adjusts colors on the screen. Samsung uses chips from several different providers, therefore, there are some deviations in the chips. Others argue that the reddish-hue can be fixed in the phone’s settings. If the problem is not corrected in software, then the product could be deemed defective.
Samsung officially responded, “Colors on the screen can vary depending on the angle or the environment. They may appear distorted. This is not a defect but just a matter of settings, something that can be adjusted by the user”.
It is important to note that the red-tinge is only appearing on a few of the one million devices that have been sold since April 7th. We did not personally experience any red hue in our own review of the Galaxy S8.
The Galaxy S8 has also been in the news over its Bixby digital AI assistant, as Samsung just recently disabled the ability to remap its hardware button. Samsung is trying to enter a crowded market with Bixby that is already serviced by Microsoft Cortana, Apple Siri and the Google Assistant.
