The phone is always used in accordance with the instructions and has never suffered any fall or exposed to water. It is in a great state except for a vertical pink line that appeared on the screen. Looking at the internet it turned out that this is a defect in the model.
What can I do to solve the problem, replacing the monitor is not an option since it will not solve the problem, because the pink line may appear again.
Thank you for reaching out. The Samsung limited warranty is a repair warranty that covers the unit for parts and labor in the event repairs are needed within the first year of ownership.

My GS7 hasn't had a problem it's a batch thing, it could happen early or late it's been a common on iPhones, Galaxys and Pixels for years because they use samsung Amoled panels.
