Introduction:

The Samsung Galaxy S25 Ultra is one of the most advanced smartphones in Samsung’s lineup, featuring a high-quality Dynamic AMOLED 2X display, advanced camera systems, and cutting-edge features aimed at users who demand the best performance. Among these features, the display stands out as one of the most important aspects, offering a vibrant and immersive viewing experience. However, as with any high-end device, accidental damage to the screen is a common issue that users face. Whether through drops, impacts, or other accidents, the need for screen repairs is inevitable for many users.

This article will explore the original LCD for the Samsung Galaxy S25 Ultra, including the various models like the SM-S938B, SM-S938B/DS, SM-S938U, SM-S938U1, SM-S938W, and SM-S938N, and guide you through the process of screen replacement. We’ll also dive into the tools needed for such a replacement and provide advice on how to go about it in the safest and most cost-effective manner.

1. Overview of the Samsung Galaxy S25 Ultra:

The Samsung Galaxy S25 Ultra was released as a flagship smartphone, offering a premium experience for users. With a large 6.8-inch Dynamic AMOLED 2X display, 120Hz refresh rate, and Quad HD+ resolution (3088 x 1440), the phone offers stunning visuals and an incredibly fluid touch experience. The screen is protected by Corning Gorilla Glass Victus 2, which provides some degree of durability against drops and scratches.

In addition to its stunning screen, the Galaxy S25 Ultra is equipped with impressive internal specifications such as a Snapdragon 8 Gen 2 chip, up to 12GB of RAM, and a 200MP main camera that sets new standards for mobile photography. However, even with this level of build quality, accidents can happen, and the screen may require replacement over time.

Understanding the LCD screen and knowing how to replace it properly is crucial for ensuring that your device continues to perform optimally, both in terms of display quality and overall functionality. For those who prefer DIY repairs, it’s also important to be aware of the tools and techniques needed to replace the LCD safely.

2. Technical Specifications of the LCD:

The Samsung Galaxy S25 Ultra uses a Dynamic AMOLED 2X display, which is the latest iteration of Samsung’s AMOLED technology. This display type is known for its vibrant colors, deep blacks, and efficient power consumption.

• Screen Size and Resolution: The display measures 6.8 inches diagonally and offers a Quad HD+ resolution of 3088 x 1440 pixels. This ensures that the Galaxy S25 Ultra’s screen delivers a pixel density of 500+ PPI (pixels per inch), offering incredibly sharp visuals.
• Color Accuracy: The Dynamic AMOLED 2X display is capable of reproducing 100% of the DCI-P3 color gamut, which means it can display a wide range of colors. This makes it ideal for media consumption, gaming, and other content creation activities.
• Refresh Rate: The screen supports a 120Hz refresh rate, which allows for smooth scrolling and improved touch sensitivity. It also supports adaptive refresh rates that adjust based on the content being displayed, helping to save battery life when high refresh rates are not needed.
• HDR Support: The display supports HDR10+ and offers high peak brightness levels, allowing users to enjoy vivid content with enhanced contrast and color accuracy.
• Protection: The screen is protected by Corning Gorilla Glass Victus 2, which offers enhanced durability against scratches and drops. Despite its strength, Gorilla Glass is not invulnerable, and drops from significant heights can still result in cracks or breakage.

3. Construction and Materials Used:

The LCD of the Galaxy S25 Ultra is constructed using several advanced materials to provide durability, color accuracy, and high brightness. The Dynamic AMOLED 2X panel is composed of multiple layers, including a touch sensor, a polarizer layer, and the actual AMOLED display layer. These layers work together to produce sharp and vibrant visuals while maintaining efficiency in power usage.

• AMOLED Technology: AMOLED (Active Matrix Organic Light Emitting Diode) technology allows each pixel to emit its own light, rather than relying on a backlight. This gives AMOLED screens their characteristic deep blacks and high contrast ratios, as individual pixels can be turned off completely when displaying black.
• Durability: The use of Gorilla Glass Victus 2 significantly improves the durability of the display against scratches and drops. However, over time, repeated impacts can cause the screen to lose its structural integrity, necessitating a replacement.

4. Common Issues with LCD Screens:

Although the Galaxy S25 Ultra’s screen is built to last, it is still vulnerable to certain issues over time. Here are some of the most common problems that may require you to replace the LCD:

• Cracked or Shattered Screens: One of the most common reasons for an LCD replacement is physical damage due to drops or impacts. While the Gorilla Glass protection provides some resistance, it is not completely immune to cracks or shattering.
• Display Burn-in and Image Retention: AMOLED screens are prone to burn-in, where static images (like app icons or navigation bars) leave a permanent imprint on the screen. This issue can degrade the overall display quality.
• Touchscreen Failure: If the touchscreen becomes unresponsive or fails to register touches, it may indicate a problem with the LCD assembly. This could be due to a faulty digitizer or a software issue, but in some cases, replacement is the only option.
• Color Distortion or Pixel Issues: Over time, the AMOLED display may develop color distortions or dead pixels. These issues can be caused by manufacturing defects or prolonged use of certain display settings.
• Screen Flickering: Another potential issue is flickering or ghosting on the display, which may result from a defective LCD or internal components like the GPU or the display driver.
