Update on my Samsung S23 Ultra issue (dead pixels):

Today I went to the Samsung Service Center at Lowyat Plaza for the dead pixel problem near the camera bump. The staff told me the whole screen needs to be replaced and it would cost around RM1300 including all fees. They also mentioned dead pixels usually spread across the screen over time, and in my case it might have been caused by “pressure on that area”  though honestly, I never dropped this phone. I’ve only been using it as a backup device, mostly at home or in the car, so it’s been handled with care.

My device is 1 year 2 months old ,already out of warranty. I requested if they could replace the screen the same way they are doing for the green line cases, but they refused. Apparently, Samsung only covers the green line issue under their special replacement program, but not dead pixels.

Honestly, I feel like Samsung’s quality has gone downhill these days. For a flagship device like the S23 Ultra, you really don’t expect dead pixels to appear this soon, especially with such light usage. Quite disappointing to see this kind of issue .

Just sharing my experience here in case anyone else runs into the same situation.
