As shown in Samsung’s aftermarket OLED screen QC test video (test model Samsung Galaxy S21). Touch functions, color saturation, and more testing are all perfect, but it has a shadow that shows in white and green color screen tests. Even if that shadow is barely visible and will not be affected by daily use. Unfortunately, this screen still cannot pass our rigorous QC test.
