In the battle between two flagship smartphones released in 2020—the iPhone 12 and the Samsung Galaxy S20—camera performance was a key battleground. Apple claimed superior computational photography, while Samsung pushed hardware limits with higher megapixel counts and advanced zoom. But when real users take the shot, who actually delivers better photos? The answer isn’t as simple as specs suggest.
Sensor Specs and Hardware Differences
The foundation of any camera system lies in its hardware. On paper, the Galaxy S20 appears to have an edge. It features a 12MP main sensor (f/1.8 aperture) alongside a 64MP telephoto lens and a 12MP ultra-wide. Its high-resolution telephoto allows for 3x hybrid zoom and up to 30x digital zoom, a significant advantage for distant subjects.
In contrast, the iPhone 12 uses a dual-camera setup: a 12MP main sensor (f/1.6 aperture) and a 12MP ultra-wide (f/2.4). While it lacks optical zoom beyond 1x, Apple compensates with Smart HDR 3 and Deep Fusion—advanced image processing technologies that enhance detail and dynamic range.
The iPhone 12’s wider f/1.6 aperture captures more light than the S20’s f/1.8, giving it a theoretical advantage in low-light conditions. However, Samsung counters with Nonacell pixel-binning technology, combining nine pixels into one to improve low-light sensitivity on its 64MP sensor.

Photo Quality: Daylight and Dynamic Range
In daylight, both phones produce excellent results, but their philosophies diverge. The Galaxy S20 tends to oversharpen images and boost saturation, especially greens and blues. This can make skies look artificially vivid and skin tones slightly warm. While pleasing at first glance, these edits can feel less natural over time.
The iPhone 12 takes a more conservative approach. Colors are accurate, dynamic range is well-balanced, and highlights are preserved without blowing out. Smart HDR 3 excels in backlit scenes, retaining detail in both shadows and bright areas. For photographers who prefer editing flexibility, the iPhone’s neutral baseline offers more room for post-processing.
Low-Light Performance: Night Mode Showdown
Night mode has become a standard benchmark. Both phones include dedicated night modes, but implementation differs.
The iPhone 12’s Night mode activates automatically in low light and supports all rear cameras, including the ultra-wide. Exposure times adjust dynamically, typically ranging from 1 to 3 seconds. The result is consistently clean, noise-free images with natural color reproduction. The f/1.6 aperture helps gather more light, making the iPhone particularly strong in dim indoor settings.
The Galaxy S20 also performs well in night mode, but results can be inconsistent. In some cases, it applies excessive sharpening or brightness, leading to halo effects around light sources. However, in very dark environments, its AI-powered multi-frame processing sometimes captures slightly more shadow detail—though often at the cost of realism.
In side-by-side tests conducted by independent reviewers, the iPhone 12 edges ahead in overall consistency, while the S20 occasionally captures brighter scenes but with less accurate textures.
Zoom and Telephoto Capabilities
This is where the Galaxy S20 clearly outperforms the iPhone 12. With its 3x optical zoom lens (equivalent to 76mm), the S20 delivers sharp, detailed close-ups without relying on digital cropping. At 10x digital zoom, it still maintains usable detail thanks to its 64MP base resolution.
The iPhone 12, lacking a dedicated telephoto lens in this generation, relies entirely on digital zoom. While computational enhancements help, anything beyond 2x zoom shows noticeable softness. Users needing frequent mid-to-long-range shots—such as concerts, wildlife, or portraits with compressed backgrounds—will find the S20 far more capable.
For ultra-wide photography, both phones offer similar 12MP sensors with ~120-degree fields of view. The iPhone 12 corrects distortion more seamlessly, producing straighter lines at the edges. The S20’s ultra-wide is slightly more prone to vignetting and chromatic aberration in high-contrast scenes.
Video Recording: A Clear Winner Emerges
When it comes to video, Apple doesn’t just compete—it dominates. The iPhone 12 introduced Dolby Vision HDR recording at 4K up to 60fps, a feature unmatched by any Android phone at the time, including the Galaxy S20.
Dolby Vision adds dynamic metadata that optimizes brightness, contrast, and color frame-by-frame, resulting in cinematic-quality footage. Combined with excellent stabilization and rich audio capture, the iPhone 12 became a favorite among mobile videographers.
The Galaxy S20 supports 8K video at 24fps, which sounds impressive but comes with major caveats: limited stabilization, rapid battery drain, and massive file sizes. Most users found 4K 60fps more practical, but even then, the lack of HDR video grading options made final output less vibrant compared to Apple’s ecosystem.
| Feature | iPhone 12 | Galaxy S20 |
|---|---|---|
| Main Sensor | 12MP, f/1.6 | 12MP, f/1.8 |
| Ultra-Wide | 12MP, f/2.4 | 12MP, f/2.2 |
| Telephoto | Digital zoom only | 64MP, 3x hybrid zoom |
| Night Mode | All cameras, auto-activation | Main and front only |
| Video Max | 4K Dolby Vision HDR @ 60fps | 8K @ 24fps, 4K @ 60fps |
| Slow Motion | 1080p @ 120/240fps | 720p @ 960fps |
Real-World Example: Concert Photography Test
A freelance photographer tested both devices at a dimly lit indoor concert. Lighting was erratic, with strobes and backlighting creating challenging conditions.
Using the iPhone 12, she captured several clear shots with accurate skin tones and minimal noise. Night mode activated automatically, and Smart HDR preserved facial details despite harsh stage lighting. Video clips showed smooth stabilization and clear audio separation.
With the Galaxy S20, she was able to zoom in on distant performers using the 3x telephoto, capturing moments the iPhone couldn’t frame. However, some photos showed over-sharpened edges and unnatural color tints. The 8K video option was too unstable and drained the battery in under 30 minutes.
Her verdict? “The iPhone gave me reliable, broadcast-ready video. The S20 let me get closer, but I spent more time editing out artifacts.”
Expert Verdict: Who Wins the Camera Battle?
The question isn’t whether Apple won outright—but what kind of winner you’re looking for.
If your priority is consistent photo quality, true-to-life colors, and best-in-class video, the iPhone 12 is the superior choice. Its software integration, HDR processing, and Dolby Vision support set a new standard for mobile filmmaking.
But if you value zoom flexibility, high-resolution stills, and experimental features like 8K video, the Galaxy S20 offers tools the iPhone lacks. It rewards users willing to tweak settings and accept occasional processing quirks.
“The iPhone 12 proves that fewer megapixels don’t mean lower quality. Apple’s focus on computational photography pays off in everyday usability.” — TechRadar Mobile Review, 2020
Frequently Asked Questions
Can the Galaxy S20 shoot in RAW format?
Yes, the Galaxy S20 supports RAW capture via Pro mode in the native camera app or third-party apps like Adobe Lightroom. This gives advanced users greater control over post-processing.
Does the iPhone 12 have a better front camera than the S20?
The iPhone 12 features a 12MP TrueDepth front camera with Night mode and Deep Fusion, offering excellent low-light selfies. The S20’s 10MP front camera is good but lacks Night mode, making it less effective in dark environments.
Which phone has better portrait mode?
The iPhone 12’s portrait mode produces more natural depth maps with accurate edge detection, especially around hair and glasses. The S20 sometimes struggles with complex backgrounds, creating halos or blurring parts of the subject.
Action Checklist: Maximizing Your Smartphone Camera
- Enable HDR/Night mode for balanced exposure in challenging light
- Clean lenses regularly with a microfiber cloth to avoid smudges
- Use a tripod or stabilize elbows against your body for long exposures
- Shoot in landscape orientation when possible—more pixels, better stability
- Review photos on a larger screen to assess true detail and noise levels
- Use grid lines to apply the rule of thirds and improve composition
- Limit digital zoom; crop later if needed to preserve quality
Final Thoughts: Beyond the Spec Sheet
The iPhone 12 vs Galaxy S20 camera debate reveals a deeper truth: hardware alone doesn’t define image quality. Apple leveraged its tight integration between silicon, software, and sensors to deliver a cohesive, reliable experience. Samsung offered more tools and higher specs, but with trade-offs in consistency and realism.
Did Apple win? In terms of real-world usability, video excellence, and color accuracy—yes. But Samsung earned respect for pushing boundaries in zoom and resolution. The “winner” depends on how you use your phone.
