Google Pixel 4a versus Samsung Galaxy Note20 Ultra camera shoot-out

Can the sheer force of hardware on the Note20 win over the Pixel 4a’s image-processing power?

The two biggest Android phones of the moment couldn’t be more different. They’re so different, in fact, that there’s £830 between them: The Google Pixel 4a costs just £349, and the Samsung Galaxy Note20 Ultra will set you back a whopping £1,179. But while it’s crazy to compare things like performance, design or battery life between phones so different in price, the

camera is another story. The Pixel 4a’s photography chops are more high-end than its price tag would suggest. It has the same main camera as the £829 Pixel 4 XL, as well as the same camera app features, including Night Sight and Live HDR+. And because it’s a Google phone, we know the processing is off-the-charts awesome. But can it stand up to a phone that costs nearly four times as much? Let’s find out.

BRIGHT LIGHT

In good lighting, both of these phones perform incredibly well. As you can see in the photos below, both cameras were able to capture impressive detail and colour, with the Note20 Ultra amping up the saturation just a bit more than the 4a. The Pixel 4a captures a bit more leaf detail even in places where the background is blurred, or the lighting is a touch on the dark side.

The clarity and detail on the stigma are very impressive in the Note20’s shots. That’s aided in part by the Note20 Ultra’s new laser autofocus, which locks in on its subject very quickly and isn’t fooled by subtle movements caused by the wind. For better or worse, you’re going to get Samsung’s usual oversaturation as you can see in most of the photos here, but that’s mostly subjective. I prefer duller, more realistic shots, but many people like the vibrancy Samsung’s production adds to photos.

However, I found that it tends to focus so well, the surrounding scene was in a constant state of blur even when I wasn’t using Live Focus. It’s easiest to see in the pictures of the thorns above. Where the Pixel 4 zeroed in on the thorns and kept some of the detail on the surrounding leaves, the Note20

Ultra had a tougher time distinguishing among all the green. And in the photo below, you can already see blurriness around the leaves of the flower, where the Pixel 4a keeps things in focus.

This is something of an extreme example, but the Note20 Ultra’s laser autofocus is definitely aggressive. I expect it’s something Samsung can dial back in future software updates.

LOW LIGHT

Google kicked off the race to take the best low-light shots with Night Sight on the Pixel 3. Even without the dedicated Pixel Visual Core processor, you’re getting excellent low-light photos on the 4a.

Samsung has made great strides with its own low-light mode on the Note20 Ultra as well. With a decent amount of ambient light, otherwise dark photos were nicely brightened on Note while still preserving shadows, with even greater detail

than the Google Pixel 4a as seen in the photos above. When the light is nearly all gone, however, the Pixel 4a performs a little better thanks to Google’s AI wizardry. The photos above were taken in near-total darkness. While neither camera took a flawless shot, the Pixel 4a grabbed more of the colour and detail of the original, while the Note20 merely brightened things.

PORTRAITS

The Note20 Ultra has a second zoom lens to work with, so it should be the better portrait taker. For the most part, it is. However, the Pixel 4a more than holds its own against Samsung’s superior hardware. As you can see overleaf, both portrait modes do a fantastic job of pulling out the subject from a busy background and generating nice background blur with

little effort. However, the Note20’s extra lenses make edges a little bit sharper.

MOTION

With a single 12Mp lens, you’d expect the Pixel 4a action shots to be extremely blurry. Once again, Google’s tremendous processing picks up the slack. From near and far, both phones snapped motion shots as if the subject were standing still, as you can see in the photos of splashing water below.

ZOOM

Even though Samsung has dialled it back to 50X from the S20 Ultra’s insane 100X, the Note20’s premier feature remains its Space Zoom. Samsung claims you’re getting ‘super resolution’ at 50X, way further than the Pixel 4a’s 7X. If you want the most zoom, there’s no contest between the two phones.

But even if you’re sticking to less than 10X zoom, the Note20 is the superior telephoto phone. At max zoom, the Pixel 4a is noticeable noisier than the Note20 Ultra, and less accurate all around. From the blurry words to the blown-out colours, the Pixel 4a struggles mightily without a dedicated telephoto lens, giving the Note20 Ultra a big advantage.

The Samsung Note20 Ultra, left, has incredibly fast and precise autofocus, which works well when your subject stands out.

The Note20 Ultra’s laser autofocus, left, works against it in this very green photo, as it struggled to lock onto the pointy thorns.

The laser autofocus sometimes worked a little too well on the Galaxy Note20, as you can see in the blurriness around the center of the flower, left.

Samsung has greatly improved low-light performance on the Note20 Ultra, left, with excellent detail, shadows, and brightness as compared to the Pixel 4a.

In extreme low light, the Note20 Ultra, left, took the brighter picture, but the Pixel 4a had better clarity and colour.

The Pixel 4a, right, is able to handle portraits very well even with just a single lens, but you can see some slight blurriness around the edges. The Note20 Ultra is consistently sharp.

Both cameras are able to capture motion very well, though here the Note20 Ultra’s over-saturation, left, works in its favour.

As you can see, there’s no comparison between Samsung’s Note20 Ultra, left, and Google’s Pixel 4a when it comes to zooming.
