I've been using the S21 Ultra mobile for more than two years. I had a positive experience with it, and it's one of the best smartphones ever made. My gadget had a software upgrade last week, and I'm done with it. Following that, for the past three days, I have noticed a vertical green line on the right side of my phone's screen.
I can assure you that my phone did not fall or suffer any physical harm to the screen or other sections of the mobile body.
While researching this problem online, I found that various flagship models from the S series and Note series are currently experiencing these green line issues after software updates.
Therefore, kindly take this matter seriously and lend me your strong support.
