My Samsung s21 got a green line yesterday out of nowhere. the phone was in the charger and afer I came and I saw this greenline. Should I go for a screen replacement immediately or else if I keep this for a sometime will it be more worst?
Hi, I am also having the same issue with my s21+. I suggest reaching out to Samsung's customer care through WhatsApp.
File an official complaint about the problem, and they will provide you with a complaint ID for reference. Within 1-2 working days, you can expect a call from them. Then highlight that it's not physical damage but a common problem in the S21 series.
Now S20 users can have a free one-time display replacement as it identifies as a common issue. So, it's important to request Samsung to provide the service and support we deserve.
