Yesterday after I plugged headphones into brand new S20+ (Exynos) phone, new firmware update appeared on screen, and after installing it I have noticed a little bit later green vertical line on screen.
I've tryed restart and boot into safe mode, but didn't help. Also I've tryed test by typing in Phone app *#0*# and activating red, green, blue calibration several times but with no results.I think it is a software issue because it coincided with that
firware update and my phone never drop or got hit by something.
Please help 😞
Solved! Go to Solution.
My phone was brand new back then so they repair it inside warranty, free of charge.
I'm not 100% sure but probably phone screen needs to be replaced and it costs around 250€.
My advice to you is to check with samsung service if they need to replace the screen and how much does it costs. And continue to use the phone as this is not that much of a deal, until you completely broke the screen and then replace it, because they are so easy to break...
