Apple Lossless Audio CODEC (ALAC), published a support document last night trying to get rid of a problem that some customers will report in stores and could use to return iPhone X phones. I told you last night when I published my impressions of the iPhone X that the screen displays different colors depending on the angle from which you look at it, but it is enough to tilt the phone a little for the change to be substantial.
Changes in colors and shades with a simple tilt
Apple says that it is normal for an OLED screen to have changes in the colors and shades of the screen, the iPhone X suffers from this problem and they call it a problem because it becomes annoying over time. Basically, while using the iPhone X in an application with a white or light gray interface, you will see that the shade of colors changes when you slightly tilt the phone, warm colors becoming cold and vice versa, everything being completely new for an iPhone owner.
“If you look at an OLED device from a sharp angle, you might notice slight changes in colors and hues. This is a characteristic of OLED displays and is normal behavior.”
I have to admit that I did not encounter this problem even with the Samsung Galaxy S8 or Samsung Galaxy Note 8, otherwise I would have noticed it, as it is not as prominent as in the case of the iPhone X. In applications with a colored background, you will not notice major changes in the color shade of the iPhone X screen, but in the rest of the applications with a very light background, you will notice this very quickly, but it seems to be perfectly normal.
Super Retina with burn-in, meaning the persistence of images, or the remanence of images
The iPhone X's Super Retina screen will be affected by what Android fans know as burn-in, i.e. image persistence, or image retention, as Apple explains. More precisely, on the iPhone X screen, some images of user interfaces, or other application interfaces used by us in daily use, could remain fixed in pixels, even when a different image is displayed.
"In the case of prolonged use, OLED displays can also show some slight changes in terms of the visual component. This, too, is normal behavior and may include 'image persistence' or 'image lingering', situations in which slight reminiscences of an image appear on the display after a new image appears on the screen."
Apple says the iPhone X's Super Retina display was designed to be the best in the industry in terms of reducing the lingering effects that affect OLED screens. Despite this, those from Apple confirm the fact that even the iPhone X can and will be affected by this problem in the case of long-term use, so you'd better be prepared for it.
How to protect iPhone X's OLED screen
To protect the OLED screen of the iPhone X against problems with the persistence or remanence of images, Apple avoids displaying the same image for a long period of time with the brightness set to the maximum level. The images must not have any high contrast when displayed at maximum brightness, otherwise there is a very high chance that the screen will suffer from burn-in, and Apple may refuse to change it.
iPhone X was received, for the most part, quite well by customers, with a lot of praise, but we will definitely see the first complaints about burn-in or changing color shades.
