Samsung just announced 3 brand new smartphones - check out the Galaxy S20, S20 Plus, and S20 Ultra

Here they are: the Galaxy S20, S20 Plus, and S20 Ultra.

The Galaxy 20 has a 6.2-inch screen.

The Galaxy S20 Plus has a 6.7-inch screen.

And the Galaxy S20 Ultra has a 6.9-inch screen.

There's little to point out about the back, other than the new camera module design. Apart from that, it's a slab of glass with curved edges.

In many respects, the Galaxy S20 phones are a simple refresh and update over 2019's Galaxy S10 phones.

At the end of the day, the Galaxy S20 phones are just that — phones. They look and feel like your typical high-end flagship devices from Samsung. They're slabs adorned in premium glass and metal, and they contain many of the ingredients that made previous Samsung Galaxy phones so good and desirable, like Samsung's best-in-class screens, gorgeous design with narrow bezels and curved side edges, a punch-hole-style selfie camera to avoid the divisive screen notch, top-of-the-line specs, great cameras, and every feature under the sun.

Here are some of the high-end specs shared by all three models, none of which should be too surprising for the keen-eyed smartphone fan:

• Qualcomm Snapdragon 865.
• A generous 12 GB of RAM for fast and smooth multi-tasking.
• 128 GB of storage with microSD expandable storage. (512 GB option for the S20 Ultra).
• Triple-camera systems.
• Fast 25W chargers (45W option for the S20 Ultra).
• In-display ultrasonic fingerprint sensors.
• Big batteries.
  • The Galaxy S20 has a 4,000mAh battery.
  • The Galaxy S20 Plus has a 4,500mAh battery.
  • The Galaxy S20 Ultra has a 5,000mAh battery.

In other respects, the Galaxy S20 phones are massive leaps. All three models can connect to a 5G network, but only the S20 Plus and S20 Ultra connect to the "fastest" 5G network.

This will be Samsung's first range of smartphones where all models support 5G connectivity.

The Galaxy S20 and S20 Plus can connect 5G networks, but only those in the low- and mid-band networks. That's to say they'll still achieve great speeds that should be significantly faster than the current 4G LTE networks, but they're not the fastest 5G networks around.

The Galaxy S20 Ultra can connect to high-band "mmWave" 5G networks — those that can theoretically achieve those crazy gigabit-per-second data speeds that's likely faster than your home's internet speeds.

This kind of mmWave 5G network is only viable inside cities due to their short range limits, whereas the low and mid-band 5G networks have greater range and can better serve those outside of cities.

5G connectivity is a big leap, but it's one that most smartphones of 2020 will also adopt. That's because the Snapdragon 865 chip from Qualcomm comes with 5G connectivity by default, meaning any phone that runs on the Snapdragon 865 will also have 5G.

I should mention that even though the big flagship Android phones of 2020 running the Snapdragon 865 will have 5G whether you like it or not, it doesn't mean everyone will be able to connect to a 5G network. 5G coverage is still fairly spotty on most carriers,

So far, T-Mobile has the widest-reaching 5G network, which is on the low band. Other carriers have focused on faster mid- or high-band 5G networks, but those 5G networks are found in fewer locations around the country.

Samsung gave its Galaxy S20 phones a big screen upgrade.

Samsung phones have some of the best screens around, but they were outshone in 2019 by OnePlus, which adopted screens with 90Hz refresh rates that oozed a premium attitude that surpassed Samsung's Galaxy S10 line with 60Hz screens.

For the Galaxy S20, Samsung is surpassing OnePlus' 90Hz screens on the OnePlus 7 series with its own 120Hz screens. But note that 120Hz refresh rates is only available with the FHD 1080p resolution, not the WQHD 1440p resolution that the screen is capable of.

High refresh rate screens make for an ultra-smooth experience while navigating around the Android operating system and apps on the Galaxy S20, but you won't see much of a difference on content like videos and games that don't support 120Hz.

To be clear, there aren't a lot of tangible benefits with high-refresh-rate screens. Rather, they offer an aesthetic that makes the device feel faster and more powerful.

Samsung says the cameras in the Galaxy S20 phones are the biggest leap since the Galaxy S7 from 2016.

For the S20 line, Samsung added larger sensors in its cameras that are designed to be clearer, have more detail, and handle low-light better. As expected, the Galaxy S20, S20 Plus, and S20 Ultra don a regular wide camera, an ultra-wide camera, and a zoom camera.

The Galaxy S20 and S20 Plus have a 64-megapixel sensor that takes 12-megapixel photos with the regular and ultra-wide lenses.

It takes 64-megapixel photos for the 3X optical zoom lens, which can achieve up to 30X zoom with optical and digital zooming. The Galaxy S20 Ultra has a slightly different camera setup, which I'll get to later.

To note, all the Galaxy S20 models can record 8K video at 30 frames per second, which is astounding, if somewhat superfluous for people who don't own 8K TVs. Of course, Samsung conveniently offers 8K TVs.

The Galaxy S20 Ultra has a 108-megapixel camera that can zoom all the way to a crazy 100X.

The Galaxy S20 Ultra takes standard 12-megapixel photos for the regular and ultra-wide lenses, but it employs a gigantic 108-megapixel sensor for its zoom lens. Combined with a periscope-style assortment of mirrors and lenses, the Galaxy S20 Ultra can achieve 10X optical zoom, and up to 100X zoom with optical and digital zooming.

We did a quick test of the Galaxy S20 Ultra's zooming, and it was pretty impressive!

At about 37X zoom, the Galaxy S20 Ultra took an amazingly clear zoomed photo of a book on a shelf that was about 20 feet — about six meters — away.

Speaking of leaps, the camera on the Galaxy S20 Ultra makes for a massive bump.

There's no escaping the Galaxy S20 Ultra' large camera bump. It's is very much there. But bumps aren't really a big deal, and they're often hidden by cases, anyway.

Samsung has a neat new camera mode called Single Take that takes a bunch of photos and video from a single tap of the shutter button instead of taking several different photos and switching between different modes.

The new Single Take mode takes short videos, regular photos, portrait-mode photos, cropped photos, and ultra-wide photos from a single press of the shutter button.

The idea here is to make sure you get the shots and videos you want from tapping the shutter button once rather than switching between modes and taking various photos yourself. Single Shot will also use AI to help you pick the best photo of the bunch. After you tap the shutter button, you get your pick of various videos and photos:

Samsung's Galaxy S20 offer some big changes in a familiar package.

Indeed, Samsung hasn't reinvented anything in particular — that's where its foldable smartphones come in. But more so than the last few years, the Galaxy S20 line is a big refresh on the inside. While they look familiar, the Galaxy S20 phones will offer a totally different feel than previous Galaxy phones because of the new 120Hz screens.

And I'm keen to check out the refreshed cameras, but I'm wary about the improvements that Samsung focused on, including clarity and detail. In my mind, clarity and detail weren't as much of a problem as was Samsung's tendency to over-process photos, making them appear artificial and flat compared to photos from other great smartphone cameras, like the iPhone and Google Pixel phones.

All this to say that only good, quality time with each device will truly tell how worthy these new devices are. As always, look out for the reviews before clicking the buy button.
