I'm using Note 20 Ultra. Yesterday while using it, suddenly a green line came on the mobile screen. However, there is no accidental record of my phone.

What to do about it? Same with me, no accidental record

I have the same problem too with my Galaxy Note S20 Ultra 5G! This is so stressful. I have followed the https://www.samsung.com/uk/support/repair/ . It requires me to Master Reset my phone and potentially lose all my data 😞.

Can anyone share if resetting your device fix the problem?

After 2 months now, I got another green line

:(. Samsung should pay me for this. It's very hard to use phone with 2 vertical lines like this.

I just had the exact same issue. My Note 20 Ultra installed an update after I rebooted it and now it has that nasty green vertical line on the left side of my screen. Very disappointed. My next smartphone will NOT be a samsung.

It jist happened to me too. So frustrating. Samsung should definitely make it up to customers at no additional cost, after all this is an expensive phone.
