Yesterday (2nd Nov 2023) I woke up to a very bright pink line on my S21 Ultra and I wasn't sure what caused it, I'm usually a very careful person with my phone hence, I was 100% sure I didn't drop the phone before I got this random display line.
I spoke to Samsung through WhatsApp on it, and I tried all the steps they asked me to do, still it wasn't going anywhere. After reading and researching all day what I found was this was due to the latest OneUI software update and all Series of Galaxy S models (higher that 10 mostly) has been constantly getting this issue.
I was also surprised to see many owners of S21 Ultra here in Sri Lanka got the same issue exactly yesterday.
I'm usually a very dedicated member when it comes to Samsung products ( I have an entire ecosystem of their products) but this was a MAJOR turn off. ABSOLUTELY DISAPPOINTED! will not be investing in any Samsung related products again!
