The Galaxy S25 Edge features a revolutionary micro-LED display that outshines any other smartphone.

In 2025, Samsung has once again raised the bar for smartphone displays with the release of the Samsung Galaxy S25 Edge. While many competitors are still refining OLED technology, Samsung has taken a bold leap forward with its latest micro-LED panel. In this review, we'll explore how this cutting-edge display technology combines with the device's 5.8mm ultra-thin design to create one of the most impressive smartphones ever made.

Display Technology: A Quantum Leap Forward

The heart of the S25 Edge's visual excellence is its groundbreaking 6.7-inch micro-LED screen:

2400×1080 resolution with 492 PPI density
Adaptive 1–120Hz refresh rate
2,500 nits peak brightness (HDR mode)
Quantum Dot Enhancer for 110% DCI-P3 coverage

This new display eliminates the air gap found in traditional panels while maintaining perfect black levels and infinite contrast. The result is an image that appears painted directly on the glass surface.

Micro-LED: The Future of Mobile Displays

Samsung's implementation of micro-LED technology represents a significant breakthrough for smartphones:

Self-emissive pixels eliminate backlighting needs
Near-zero power consumption in static scenes
Improved response time (<1ms vs 3ms on OLED)
Higher brightness without increased power draw

A side view showcasing the incredibly slim profile of the Galaxy S25 Edge with its advanced micro-LED panel.

Unlike traditional LCD or OLED displays, micro-LED uses microscopic LEDs as individual pixel sources, resulting in unparalleled image quality and efficiency.

Brightness and Visibility

The S25 Edge sets a new standard for visibility:

2,500 nits peak brightness in HDR mode
1,200 nits sustained brightness
Outdoor Mode 3.0 with AI-enhanced readability

These specs make the S25 Edge the most readable smartphone under direct sunlight, outperforming even the brightest OLED displays by over 40%.

Touch Responsiveness and Interactivity

Samsung has significantly improved the touch experience on the S25 Edge:

240Hz touch sampling rate in gaming mode
Gaming Booster 2.0 for reduced latency
Haptic Touch Engine with 16-level pressure sensitivity

For creative professionals, the display now supports Pencil Mode 2.0, offering enhanced precision for stylus use.

Design: Thinness Meets Strength

The S25 Edge's 5.8mm thickness is achieved through innovative engineering:

Titanium frame for structural rigidity
Gorilla Glass Ceramic 2 protection
IP68 rating for water and dust resistance

Despite its slim profile, the device maintains exceptional durability thanks to a layered construction approach that distributes impact forces efficiently.

Under-Display Camera Perfection

Samsung has perfected its under-display camera technology in the S25 Edge. The 12MP front camera is completely invisible during normal use, with no visible pixelation or color shift. When activated, the display area above the camera becomes perfectly transparent while maintaining 400 PPI resolution around the imaging area.

Performance: Supporting Advanced Display Features

To handle the immense data throughput from the high-resolution micro-LED display, the S25 Edge features the powerful Qualcomm Snapdragon 8 Elite chipset built on a 3nm process. Paired with 12GB LPDDR5X RAM and up to 512GB UFS 4.0 storage, this phone handles even the most demanding visual tasks effortlessly.

Software: Enhancing the Visual Experience

Running on Android 15 with One UI 7, the S25 Edge offers several display-specific enhancements:

Eye Comfort Shield 2.0: Adaptive blue light filtering
Pro Video Mode: Log gamma support, waveform monitor
Gaming Booster 2.0: Enhanced video encoding during gameplay

Pricing and Availability

The Galaxy S25 Edge starts at:

$1,049 for 256GB
$1,149 for 512GB

It’s available from Samsung, Amazon, and other major retailers.
