The official start of sales of the new flagship Samsung smartphones will take place on April 21 (April 28 in Russia), but some buyers from South Korea have already received pre-orders for their Galaxy S8 and Galaxy S8 +. And, as is often the case with the release of any product, the first complaints from social networks appeared from newly made owners – for some devices the screen has a reddish tint, rather than white. Samsung representatives quickly responded to the comments, explaining that it was not at all the quality of the installed OLED screens. Hue can be adjusted through the program settings of the screen. However, owners of fresh flagships emphasize that manipulating the settings does not help get rid of the red tone. Analyst Neil Shah from Counterpoint Research believes that using OLED screens with Deep Red technology in smartphones just gives users a reddish effect on white background. To minimize or completely remove the shade, according to a specialist, software calibration will help.
