A number of Galaxy S21 series users have been complaining about the infamous “green line” issue on their phones. Galaxy S21 Ultra and Galaxy S21 FE users appear to be mainly affected.
Samsung Galaxy S21 series green line issue
Several users have posted on X and Reddit about the sudden appearance of a green line on their Galaxy S21 series phones. Notably, this started appearing after certain software updates on their phones.
A Galaxy S21 Ultra user claimed on X the other day that the green lines surfaced after patching to the April security update.
This issue isn’t limited to just Samsung phones as you may have heard about other brand’s phones facing this issue.
Even though it’s known to happen following a software update, it doesn’t seem entirely a software bug. If it is, it could be easily fixed.
Unfortunately, the green line issue is said to be caused by a hardware defect. It is found on AMOLED displays with loose, damaged, or defective display connectors or flex cables. These internal components connect the motherboard and the screen.
