It's been two weeks since I swapped my Samsung S10 Lite for the S21 Ultra. I have a habit of working at night in complete darkness. With the S10 Lite I had no problem with this, I worked with the screen at minimum brightness and my eyes did not get tired. After upgrading to the S21 Ultra, when working in total darkness, I feel very uncomfortable for my eyes. The first thing I did was turn on the Eye Shield and thought I would get used to the flicker of the new screen. But even after two weeks of use, I was not used to it and my eyes began to hurt more. I started to search different forums for information about this problem and found that I was not the only one who got eye pains while working with the flagships starting from the S20 series. On YouTube there is a lot of evidence that Samsung flagships flicker in the unacceptable range for safe use in total darkness. And they also point out that mid-range phones do not experience such problems. Samsung, when will you add technology like "DC Dimming" to the S21 Ultra?
