Samsung Galaxy S24

Samsung Galaxy S24 series users have encountered various display issues, with complaints flooding in regarding a grainy texture problem. Many owners have also noted washed-out colors on their displays.

Samsung is reportedly developing a vividness slider to address this issue. However, these problems aren’t limited to color inconsistencies. Reports suggest that the S24 lineup’s super-bright displays suffer from several defects.

The grainy texture on the display is particularly noticeable on dark or gray backgrounds. Reddit users have extensively discussed this issue, with a poll indicating that a majority of S24 and S24+ owners have experienced it.

Some users have even examined their devices under microscopes, revealing uneven subpixel intensity at low brightness levels. While Samsung has replaced units for some customers, others have faced challenges in obtaining replacements.

In addition to the grainy texture, some S24 users have reported seeing three horizontal bars on their displays at low brightness.  There are also complaints about excessive banding when viewing gradient images.

One Reddit user, general_clausewitz, has extensively documented the prevalence of the grainy texture across multiple devices, including personal devices, demo units, and phones belonging to others.

Vivid display mode issue

One of the big selling points for the Samsung Galaxy S24 is the display. Unfortunately, that's also one of the biggest problems facing the device, according to some users.Across social media, Galaxy S24 early adopters are finding issues with how colors are being shown on the Galaxy S24 display. Forbes found that even some users on Reddit have reportedly returned to using the previous model, the Galaxy S23, because the colors are so "dull" or washed out on the smartphone display.

Green line display issue

Samsung may be trying out some new things with the colors in Vivid display mode, but this one certainly isn't intentional. 

Some Galaxy S24 users are experiencing another, much worse, display issue: A green line appearing vertically, straight down from the top to the bottom of their screen. Some are even finding a white line going across the display too.

To make matters worse, it's not clear why this is happening — and Samsung is reportedly not taking responsibility for the issue. 

According to a post on the Samsung community forums and a report from Phone Arena, users who are experiencing this green and/or white line issue are being turned away from Samsung, claiming the responsibility to fix the issue lies with the cellular service providers like T-Mobile and Verizon. Furthermore, those Galaxy S24 owners are being given the runaround from the phone service providers, too, leaving them with no choice but to return the phone and repurchase a new one, losing out on any discounts they received from buying the Galaxy S24 the first time.

Faulty cameras

One of the major selling points of the Samsung Galaxy S24 Ultra, the priciest of the company's new line of Galaxy phones, are the cameras.

The Galaxy S24 Ultra comes with a total of four rear-facing cameras including a 12MP ultra-wide camera, a 200MP wide camera, a 50MP telephoto camera with 5x optical zoom, and a 10MP telephoto camera with 3x optical zoom.

Some unfortunate Galaxy S24 Ultra early adopters have received defective phones that jump while switching camera to zoom in. There are also issues with certain lenses producing grainy and dull photos.
