Users are reportedly reporting that a bug in the April 2024 security patch is causing a green line on the screen of Samsung phones. The issue appears to affect many different models, including expensive smartphones like the Galaxy Z Flip 3 and Galaxy S21 Ultra.

Seems like, The error is visual only and does not affect any functionality of the mobile phonebut it’s still an inconvenience. The green line is constantly displayed vertically, overlapping any content on the screen, and can scare unsuspecting users into thinking it’s a hardware problem.

UPDATE 3: So the line got thicker, brighter and greener. It is extremely bright. It seems people @SamsungIndia @Samsung mobile I don’t care, no one has contacted me yet, it’s been over 24 hours since I wrote here. @tarunvats33 @theonecid @trolling_isart @beebomco pic.twitter.com/3joQxRPbJz
