# If Samsung Aims to Retain the Best Displays, It Must Tackle These Crucial Issues
For years, Samsung has stood at the forefront of smartphone display technology, frequently recognized for offering the finest screens available. From vivid AMOLED displays to pioneering advancements such as foldable screens, the South Korean technology powerhouse has continually expanded the limits of smartphone display capabilities. Nonetheless, recent concerns regarding the Galaxy S24 Ultra’s display have surfaced, highlighting several challenges that Samsung must confront if it wishes to uphold its title as the leader in display technology. With the Galaxy S25 Ultra approaching, here’s an overview of the primary issues Samsung must resolve to genuinely affirm the label of “best displays.”

## 1. **Grainy Displays: The Mura Concern**
A prominent issue with the Galaxy S24 Ultra’s display is the “grainy” appearance that various users have noted, especially at reduced brightness settings. This occurrence, technically referred to as “mura,” arises when adjacent pixels on an OLED screen emit inconsistent brightness, leading to a patchy or uneven look. While this issue has been observed in older models, such as the Google Pixel 2 XL, its reappearance in a high-end model like the Galaxy S24 Ultra is troubling.
The graininess is particularly evident in dimly lit conditions or when the brightness is lowered, yet some users have claimed to see it even at brighter levels. This indicates a probable manufacturing flaw or insufficient calibration during fabrication. Speculations suggest that Samsung might tackle this problem in the Galaxy S25 Ultra by utilizing advanced M13+ panels, but until the device is officially launched, this remains uncertain.
**What Samsung Needs to Do:**
– Enhance quality assurance throughout the manufacturing process to guarantee pixel consistency.
– Improve calibration methods to reduce mura visibility.
– Explore the adoption of new OLED technologies or substances that minimize such concerns.

## 2. **Persistent Smudges: Oleophobic Coating Issues**
Another major grievance from Galaxy S24 Ultra users is the rapid degradation of the oleophobic coating on the display. This layer is intended to resist oils and fingerprints, keeping the screen pristine and free of smudges. However, some users report that marks on their screens have become irremovable, giving the display a constantly dirty appearance.
The sole remedy for affected users is to replace the entire display glass, which is both expensive and cumbersome. An Android Authority survey indicated that nearly 50% of Galaxy S24 Ultra users may be dealing with this challenge, underscoring the magnitude of the issue.
**What Samsung Needs to Do:**
– Utilize superior oleophobic coatings that offer greater durability and resistance to deterioration.
– Undertake comprehensive testing to confirm the coating’s longevity throughout the lifespan of the device.
– Urge users to use screen protectors to prolong the coating’s effectiveness.

## 3. **Insufficient Eye-Friendly Dimming Solutions**
As investigations into the effects of PWM (Pulse Width Modulation) dimming and LED flickering on ocular health advance, it has become evident that these technologies can lead to discomfort for certain users. PWM dimming, which modifies screen brightness by swiftly toggling LEDs on and off, can trigger headaches, eye fatigue, and other health problems for individuals sensitive to flickering.
While some manufacturers such as OnePlus, Vivo, and Xiaomi have implemented flicker-free or DC dimming alternatives to counter this issue, Samsung has yet to adopt similar measures. This is particularly disheartening considering Samsung’s standing as a market leader and its capability to influence industry norms.
**What Samsung Needs to Do:**
– Implement DC dimming or alternative flicker-free technologies in its displays.
– Present more customizable dimming settings in the menu to accommodate varying user sensitivities.
– Increase awareness regarding the potential health implications of PWM dimming and provide solutions for those affected.

## 4. **Color Calibration: Finding the Right Mix of Realism and Vibrancy**
At its debut, the Galaxy S24 Ultra’s display faced criticism for lacking the vibrant hues typical of past Samsung flagship models. While some users favored the more natural color calibration, others longed for the striking, saturated visuals that characterize Samsung displays. Eventually, the company released a software update introducing a vibrancy adjustment, enabling users to select their desired color profile.
Although this was a positive move, it underscored a more significant concern: Samsung must improve its balancing of color fidelity against user preferences right from the start.
**What Samsung Needs to Do:**
– Provide numerous color profiles at launch, incorporating options for both realistic and vivid hues.
– Offer a vibrancy adjustment or similar personalization tools from the outset.
– Conduct user feedback surveys to grasp the preferences of its diverse clientele.
