Black lines on screen Note 20 Ultra

[Juni965]

Sometimes 2 3 black lines appear when i unlock the device.

I was using lowest resolution and i noticed it 1 or 2 days ago. I never dropped it or anything like thay.

I'm a bit concerned as i bought it by saving a lot of money and doing a lot of hard work.
