On Samsung’s community forum thread, a member with the username ‘LeeYon’ described the issue saying that at first, he noticed that his phone was showing flickering lines while playing games. He pointed out that this issue was not just restricted to games as the flickering was visible even on the device’s home screen and other apps. After he contacted Samsung’s support team, he was instructed to do a soft reset on his phone. After the issue persisted, he did a factory reset on his phone and this resulted in the phone’s display turning unusable. Eventually, the Samsung customer service team had to replace the phone’s display and battery to resolve the issue.
Another forum member, Eug84, has also shared that he is facing a similar issue with his Galaxy S20 Ultra as the display is showing scan lines consistently. He has even uploaded a video on YouTube that highlights this issue. If you go through the comment section on this video, you will see that many other users are facing this issue with their phone’s display as well. While Samsung is one of the best, if not the best, display makers in the market, this issue might need immediate addressal from the South Korean brand.
