According to initial knowledge, Samsung has got the autofocus problem under control. However, in the last update, there was, unfortunately, a bug newly added.
This bug does not refer to the camera, but to the display of the Galaxy S20 series. Because the display has a slight green tint, which appears sometimes clearer for some users. The majority of the complaints concern the Galaxy S20 Ultra with the Exynos chip. Furthermore, the problem should only occur at higher refresh rates (120 Hz) and a display brightness of less than 30%.
Mainly, the users complained about the problem in some apps such as Samsung Pay, camera, calculator, Snapchat, telegram, PUBG: Mobile and Chrome.
Furthermore, some users report that the problem could be solved with the help of a factory reset. At the same time, this means that this is not a hardware defect, but a pure software problem. Samsung employees have not yet recognized the error. However, this is likely to change later and a software update will be made available.
