I'm having the same issue after update the software (greenline appeared) . I've reported and brought my phone to ASC and I even emailed to CEO Samsung (its on their website) and lodge the same report and the answer I got was OUT OF WARRANTY so can't replacement screen for free unless I pay for the screen to get it changed!.. I did highlight to them when I used my note 9 those days and my screen when green/yellowish after update software and brought my phone to ASC n they changed my screen for FOC eventho it was OUT OF WARRANTY... Hurmm Samsung is not taking any responsibility for Note 20 Ultra 5G for foc screen replacement.. They only replaced screen for foc for samsung 20+ ONLY!.. Samsung **bleep** big time!!
