The top-notch Infinity Display, the Samsung Galaxy S9 and S9+ are apparently facing some color blending issues, commonly referred to as "black crush."
Samsung's AMOLED displays are famous for their high quality and crisp details, yet they're not without a fault. Several Galaxy S9 and Galaxy S9+ users have taken to various online forums to report this black crush issue, which has previously affected other smartphones such as the Google Pixel 2 XL.
Galaxy S9 'Black Crush' Screen Issue Explained
This "black crush" screen issue refers to various dark shades displayed inaccurately. As a result, dark sections of videos or images can appear with blocks or black, pixelated, or grainy, which is quite the opposite of what you'd expect from a top-notch, high-resolution display. The visuals rendered with this "black crush" issue are with significantly less detail, like a file that's lost most of its quality after heavy compression.
Simply put, rather than showing details, screens affected by this issue will show blocks of pixelated or black images in dark sections. The Android Soul shows this issue in a sample image, with the phone above displaying the picture correctly, while the one below suffers from the "black crush" issue.
