Huawei P9 vs. Galaxy S7: Even a Leica Can't Beat Samsung
by CHERLYNN LOW Apr 20, 2016, 9:28 AM
Smartphone makers are getting really serious about cameras, with Samsung setting the tone with its unique dual-pixel sensors on the Galaxy S7 and S7 Edge. Huawei is taking on Samsung by teaming up with famed camera maker Leica on the Huawei P9, offering dual cameras for refocusing on your shot after the fact.
Is Leica's support (and co-engineering) enough to help Huawei steal Samsung’s crown as the camera-phone king? After putting the cameras on both phones through their paces, we believe the answer is a resounding no.
Methodology
We tested the cameras on both phones by taking shots in a variety of common scenarios in full auto mode and without tapping on the screen to select a point of focus or exposure. This lets the camera decide on its own what to focus on, reducing variation due to human interference. Each picture in the comparison was snapped within seconds of its counterpart.

We compared images from both devices side by side on the same desktop monitor and analyzed the photos for color, clarity and exposure.
The Devices
Samsung's Galaxy S7 and S7 Edge sport dual-pixel, 12-megapixel sensors that have 1.4-micron sensors. Paired with a maximum lens aperture of f/1.7, the new Samsung flagships let in about 95 percent more light than did their predecessors. The new dual-pixel sensors offer faster autofocus as well, great for capturing active subjects. Up front, Samsung's 5-MP selfie-shooters rock apertures of f/1.7. For our comparison, we used the Galaxy S7 Edge.

The Huawei P9's 12-MP camera rocks two f/2.2 lenses and 1.25-micron pixels, one capturing color information while the other records monochrome detail. Together, that dual-lens setup promises rich colors and great clarity, as well as a large pixel size equivalent to 1.76 microns, Huawei said. The P9's 8-MP selfie cam has a maximum aperture of f/2.4.
Round 1: Daylight landscape
I shot the Manhattan skyline from my 36th-floor balcony with both phones, and it was tough to pick a winner. Both cameras delivered rich details and great colors, but the Galaxy S7 produced deeper blue sky, better contrast and sharper lines in distant buildings, so it won in the end.
WINNER: Galaxy S7 Edge. The two phones delivered nearly identical pics in daylight, but the Galaxy's deeper colors and higher contrast made for more pleasant shots.
Round 2: Close-up food
Hate all you want, but food photography is a delicious treat for both your stomach and your eyes. Pictures of mouthwatering cuisine are a great test to see how a camera handles colors, textures and details. My tantalizing breakfast appeared bright and appetizing in the Galaxy's shot, but looked more like green eggs and bleah in the Huawei's image.
Huawei's camera looked to have more-accurate white balance compared to Samsung's slightly reddish pic. But the P9 cast a green tinge over my food. Huawei's picture also lacked the clarity found in the Galaxy S7's photo.
The Huawei P9's pictures were also consistently darker than the Galaxy S7's, as shown by these photos of a cup of frothy macchiato.
WINNER: Galaxy S7. Despite a rosy tinge that results in somewhat inaccurate colors, the Galaxy S7 Edge's warmer colors and clearer details secured it the win in this round.
Round 3: Daytime portrait
When your squad gets together for shenanigans, your camera needs to do a good job capturing all the beautiful memories. I got my girls together for a group shot on our roof, and had a tough time picking the better phone camera.
Although Samsung and Huawei both delivered solid exposure for the scene, with nearly identical colors, the Galaxy S7's picture was far sharper than the Huawei P9's. My colleague's lovely blonde hair looked like a mottled mess on the Huawei's image, while every strand was tack-sharp on the Galaxy's.
WINNER: Galaxy S7. Samsung's superior clarity beat Huawei in this round.
Round 4: Low light
Samsung continued to hog the limelight once the light fell, delivering crisper details and an overall brighter picture than Huawei's camera did.
Objects in the shadows, such as the rooftops of shorter buildings, were brighter and clearer in the Galaxy's shot, but are shrouded in darkness in the Huawei P9's.
Similarly, the Galaxy S7 Edge captured a much brighter shot, taken in near darkness, of my homemade dinner than did the Huawei P9.
With flash activated, both phones did a good job capturing the chili flakes and individual grains of quinoa on the dish. Samsung had crisper details again, while Huawei's picture looked soft. However, Huawei's phone uses a more neutral flash that made colors more accurate, while Samsung's lights had a blue tone.
WINNER: Galaxy S7 Edge. Samsung's brighter pictures in low light retain more details and colors.
Round 5: Selfie
Although the Huawei flagship has a sharper, 8-megapixel front cam compared to the 5-MP model on the front of the Galaxy S7, the P9 still lost to the Samsung device on clarity. I turned off Beauty mode in both phones to reduce blur that could be caused by software, and my hair looked sharper on the Samsung's pics.
Huawei did deliver warmer, more-realistic colors than Samsung did, with the S7 Edge's camera washing me out and making me look too pale. My hair was a more accurate shade of brown in the Huawei P9 shot, while it appeared too red in the Samsung version.
To keep the party going even in pitch-black darkness, both phones offer selfie-flash features that brighten your visage by lighting up the display. Samsung's flash was much stronger and made me look pale; the Huawei flash cast a green tinge over the image, although it kept my skin tone more natural.
WINNER: Galaxy S7 Edge. With greater clarity and more vibrant colors, Samsung takes this round.
Round 6: Special features
Leica is well-known for its cool All-Focus feature that lets you refocus your shot after you save it, and the Huawei P9 offers this tool as well. I snapped a close-up shot of my breakfast in Aperture mode, then went into the Gallery app to tweak the photo. I could tap anywhere in the picture to select that spot as a new focal point, and adjust the aperture size (which determines how shallow the focus would be).
