Some owners of Samsung Galaxy S20 + or S20 Ultra they began to report a serious flaw in their smartphone’s display which would start to appear after about a year of use. The first report was made in May by a user on the official Samsung community forum, who explained that he initially noticed some strange lines while he was playing and, after resetting the device, as suggested by the support, the display has turned green and white and becomes excessively hot if left on.
