Samsung S21+ Display Issue

My Samsung S21+ which I bought around 2 months back got display black all of sudden while I was using it. The phone was not even dropped for single time since I bought it. I took the phone to authorized service center and problem got resolved.  Service center representative told that the display had gone & they replaced it with new with no cost . However am not happy that this happened in the very early month from I bought my new phone. I am a Samsung user for more than 12 years and I expect Samsung  not to compromise on quality.
