Complaints about the latest Samsung Galaxy S21 update have begun to appear online.
It is reported that after the software update, green bars began to appear on smartphone screens. Most often, problems are observed in the Galaxy S21 Ultra and S21 FE.
The exact cause of the streak is unknown. Not all users experience this problem after updating the firmware or installing a security patch.
Android Authority believes that during a software update, older smartphones actively heat up, which causes a previously existing hardware defect in the video card assembly. suggest that this heat may weaken the adhesive holding some display components together, leading to problems with green bars.
