Our favorite smartphones from Mobile World Congress 2019 - Engadget

Posted: 02 Mar 2019 06:51 AM PST

The last week has been a whirlwind of jamón-flavored chips, 5G talk and things that fold, so naturally, we're still reeling a bit. As we begin pulling ourselves out of this trade show-induced stupor, though, we've taken stock of everything we've seen in Barcelona and compiled this list of our favorite smartphones from the show floor.

Not everything that made the cut will be a massive success, or go on sale around the world -- still, because of the ambition and ingenuity that went into each of these devices, each is worth celebrating in its own way.

Samsung Galaxy S10 and S10+ hands-on

Samsung Galaxy S10+

Alright, alright, yes — the Galaxy S10 family was revealed at an event in San Francisco, well before Mobile World Congress even started. Whatever. It's still one of the most influential devices at the show: ads are plastered on buildings across the Barcelona, and every flagship here has been compared to the standard Samsung has already set. It's big, beautiful, powerful, and it uses an updated interface that's staggeringly more pleasant to use than what we found on earlier models.

The reason the bigger model makes our list instead of its little brother is, well, because we've been testing it this whole time. The official Engadget review is still in progress, but the process of using it in Barcelona has given us time to appreciate Samsung's shifting priorities and mutually gripe about what it gets wrong. (Trust us: It's an excellent phone, but certainly not perfect.) You'll have to wait a little longer for our final verdict, but even now, it's safe to say this is one of the best smartphones you'll see all year.

Nokia 9 PureView

Seven years ago, Nokia — the original Nokia, I mean — rolled into Barcelona with an astonishingly chunky smartphone with a then-unheard-of 41-megapixel camera. The following years were a roller coaster for the company, but now the Nokia brand is back and this spiritual sequel is every bit as ambitious as the Lumia 808 PureView announced so long ago. The Nokia 9 PureView's claim to fame is the five-camera array tucked into the phone's back, all of which work together to produce highly detailed, bokeh-filled photos that none of those 12-megapixel sensors could capture alone.

At the end of the day, though, the Nokia 9 PureView is many things at once. It's an experiment in computational photography, a tool for curious camera nerds, and a limited edition device. (Nokia will only produce and sell a few thousand units before calling it quits.) With any luck though, HMD will learn from the process of building the Nokia 9 and start to bring those ambitious camera setups to the rest of its devices.

Xiaomi Mi Mix 3 5G

The Mi Mix 3 is hardly a new phone — it was announced in China in October 2018 and went on sale shortly after. It's no slouch on its own, with its Snapdragon 845 chipset, 6GB of RAM, up to 256GB of storage and a 6.39-inch slider display that locks into place with a satisfying thunk. What makes this really special, though, is its support for 5G networks. There have been no shortage of 5G devices on the MWC show floor (some functional, and some less so), but Xiaomi's Mi Mix is easily among the least expensive.

When it launches later this year, the phone is expected to cost about €600, or roughly $680. That's less than what any of Samsung's new, non-5G phones. Granted, its modem only supports so-called "sub-6" 5G, so its value will take a hit once wireless carriers start lighting up their mmWave-based networks. Still, Xiaomi's goal has always been to make cutting-edge features and performance available to more people, and the Mi Mix 3 5G feels like another step in the right direction.

Huawei Mate X

We couldn't not mention this one. Huawei is an MWC mainstay, but it has never — never — made a splash at the show the way it did this year. All the buzz is thanks to the Chinese company's new, foldable Mate X, an absolute stunner that proves Huawei is a hardware maker of the highest caliber. (Whether the company is ultimately trustworthy, though, is a question that still needs answering.) Sleek, premium design? Check. A beautiful screen that stretches edge-to-edge? Check. And support for 5G networks? Check.

The Mate isn't without its shortcomings, though. The company still hasn't offered many specifics on how durable that outward-facing, 8-inch display is — others who have attempted the feat think this design is a dead end. And my god, that price tag: certain corners of the event space collectively groaned when they learned the phone would cost €2,300 (or about $2,600) at launch. Make no mistake: very few people will ever own a Huawei Mate X, but what the company learns about making foldables might prove to be priceless.

Honorable Mention: Sony Xperia 1

Despite its incredible popularity in gaming, entertainment and consumer tech, most people wouldn't be caught dead using one of Sony's Xperia phones. That might not change with the forthcoming Xperia 1, but Sony has accepted its niche and built a love letter to creators and content consumers. That massive, 21:9 4K OLED HDR screen might feel like a remote control in your hand, but the screen is of impeccable quality. Not only that, the Xperia 1 also packs a triple camera with features culled from the company's mirrorless cameras, not to mention the ability to shoot 4K HDR at 24 fps. It's not a phone that makes sense for everyone, but people who wanted a more cinematic kind of smartphone should love it.

So, why does a phone we admittedly like only get an honorable mention? Because Sony wouldn't let us use one. By the time the show ended, we spent more time handling the illusive Mate X than we did with a fully functional Xperia 1. I get Sony's rationale here: none of the Xperia 1s at MWC were running final software, and it didn't want to show off incomplete features and give people the wrong impression. Fine. But for once, Sony has made a truly fascinating smartphone that we couldn't wait to try out, and we were ultimately left wanting.

At a Mobile World Congress keynote panel on the timing of 5G devices, Qualcomm President Cristiano Amon declared with confidence, "The phones are ready; we're just waiting for the networks."

About an hour later in a briefing room a mere 10 feet below that keynote hall, AT&T Chief Technology Officer Andre Fuetsch told CNET, "The issue is devices. Frankly, we're waiting on the devices."

After years of work on 5G networks, hyped as the life-changing foundation for tech trends like augmented reality and telemedicine, the superfast wireless technology is finally being rolled out across the globe. Carriers are turning on their networks, and virtually every major Android handset maker has talked up plans to launch a 5G device this year.

But, as evidenced by the conflicting comments from the AT&T and Qualcomm execs, things are still a little complicated. Still, while 5G at times remains a confusing mess, it's at least coming online in a real way now.

There's been a whirlwind of news. Samsung, the world's biggest smartphone vendor, unveiled the Galaxy S10 5G last week during its Unpacked event in San Francisco. Oppo on Sunday at MWC talked up its first, not-yet-named 5G phone. Later that day, Huawei showed off its 5G-powered Mate X foldable, and Xiaomi detailed its Mi Mix 3 5G. MWC also marked the debut of LG's V50 and ZTE's Axon 10 Pro, while Sony and OnePlus showed off prototypes for devices they'll launch this year.

That doesn't mean you should jump on the 5G bandwagon just yet. Here are a few reasons to wait a bit.

New networks mean tiny coverage areas

AT&T says it has the first mobile 5G network in the US, but when it comes to where you can actually tap into the next-generation service, things get a little mysterious.

"They're small pockets in the cities," Fuetsch said. "We haven't disclosed them publicly."

AT&T and Verizon have invested in superhigh frequency radio airwaves known as millimeter wave spectrum, which brings tremendous speed and capacity. The downside of that high capacity is limited range.

How limited? Think a block or two.

So even if AT&T and Verizon say they have 5G coverage in a city, you may struggle to actually get on the network, even with a compatible device. A Verizon spokesman admitted the early deployment would be small. T-Mobile Chief Technology Officer Neville Ray told CNET that his company has fired up millimeter wave spectrum that supports the upcoming Galaxy S10 5G, but that the company likely won't market the network since the coverage area is so small.

Ray said T-Mobile's full 5G launch will happen in the second half of the year. He didn't specify when, but there may not be phones that run on the company's broader 5G network until the fourth quarter, or even early 2020. That's because devices for T-Mobile's network will require Qualcomm's upcoming second-generration modem, the X55, and that isn't yet available for devices.

Smartphones coming in time for the holidays later this year will still use the first-generation modem, the X50, Qualcomm's Amon said in an interview Monday.

"There are some [handset makers] who are aggressive with their launch dates," he said. "We could see some X55s, but most of the smartphones coming from Q2 2019 all the way to the holiday season will be ... X50."

A T-Mobile spokeswoman would say only that the broader network launch will happen in the second half.

Both Ray and Fuetsch are shooting for nationwide coverage using lower frequency (and longer range) spectrum by 2020.

The carrier with the biggest early 5G coverage could actually be Sprint. Yes, that Sprint. The company said it would cover more than 1,000 square miles with its 5G networks, spread across nine cities, such as Chicago and New York.

No other carriers have talked about their full coverage range, which isn't reassuring for anyone willing to buy a 5G phone. We also don't know how much the mobile 5G plans will cost.

The first phones will be expensive

No one really knows quite what 5G devices are going to cost. Out of all the 5G handsets already announced, only two have price tags.

Huawei at MWC said its Mate X will cost a jaw-dropping €2,300 ($2,600) when it goes on sale in the middle of the year. That's pricier than feared, even though it's one of the world's first foldable phones. But Xiaomi's Mi Mix 3 5G will retail for €599 ($679) when it hits the market in May, an amount that's less than many 4G phones today.

The devices may end up being on extreme ends of the pricing scale, but there's really no way to know right now. And another wildcard is what other features are added to boost the price. The Mate X's cost is mostly because of the foldable display.

Ultimately, the additional features added to 5G phones "will determine the premium," Creative Strategies analyst Carolina Milanesi said. "Rest assured, there will be one."

Carriers are spending billions of dollars to build out 5G networks. Device makers need to use pricier components like 5G radios and bigger batteries. Those higher costs will likely flow down to you through more expensive service and phones. And the shift to 5G gives carriers and phone makers the chance to charge more for those top speeds at a time when they're not selling as many devices.

Drew Blackard, Samsung's senior director of product marketing, told CNET after the company's Unpacked event that the Galaxy S10 5G will be more of an "incremental step-up" from the $1,000 S10 Plus, not a huge jump like the $1,980 Galaxy Fold. He noted it'll be over $100 more expensive but declined to give any further specifics.

Motorola President Sergio Buniac, meanwhile, believes that though 5G devices may be more expensive, they won't be excessively so. And OnePlus aims to keep the cost of its first 5G phone "within $1,000," CEO Pete Lau said during an interview Monday.

"Initially, the price of 5G phones will be higher than 4G phones, that's for sure," Yenchi Lee, senior director of product marketing for MediaTek's wireless communications business, said in an interview Monday. The company this week unveiled its first 5G modem, which'll be in smartphones in early 2020.

Once chips like Qualcomm's new integrated Snapdragon 5G processor hit the market next year, companies making less expensive phones will also be able to include 5G in their devices.

"We're trying to get to 5G not just to that flagship tier but to other tiers as fast as we can," Qualcomm's Amon said. The integrated chip will be in phones in the first half of 2020.

The first phones work only on the carrier you bought them for

Thanks to everyone embracing 4G LTE, we'd finally gotten to the point where phones could be taken to almost any carrier and still work. Then 5G came along.

Though everyone is using the same wireless technology, the carriers are employing different bands of spectrum. And the first-generation chip and antennas can't tap into all those frequencies at the same time.

Instead, whatever 5G phone you buy that has Qualcomm's X50 modem (which is basically any 5G phone except those from Huawei) will be tied to a specific carrier. The 5G phone you buy for Verizon will work only on Verizon's 5G network.

Once the X55 chip and new Qualcomm radios are out, a phone will be able to run on all major spectrum bands, all over the world. That means we can finally get unlocked 5G phones -- if that's what the handset makers choose.

No killer apps yet

Throughout MWC, countless booths showed off how 5G can change the experience on your phone, with, for instance, video calls and polished console-level games running smoothly, thanks to much of the processing power being handled remotely.

But consumers aren't going to pay a premium just to eliminate a little buffering.

"The industry's challenge is finding what's the killer app for 5G," said Dan Hays, a consultant for PWC.

Those apps will come -- even if it takes time. Remember, until 4G improved the quality of the services, things like Uber or livestreaming through Facebook didn't exist, and watching streaming video from the likes of Netflix and YouTube didn't take off.

But in the early days, there may not be a lot of ways to take advantage of all that bandwidth.

Mobile 5G beyond phones

Though the world's biggest handset makers plan to release 5G phones as soon as possible, other, smaller players are being more cautious. HTC for one "questioned whether it was right to do [5G] on a phone." For now, at least, HTC doesn't think phones are the way to go. Instead, it's focusing on delivering 5G to customers through its 5G Hub, which'll be available in the US on Sprint's network.

"The beauty of the hub concept is it doesn't matter what device you've got," Nigel Newby-House, HTC associate vice president of product planning and go-to-market, said in an interview ahead of MWC. "Whether it's VR, notebook, tablet, this is your gateway that could be shared across devices. We're trying to spare you the cost of having 5G in your phone, tablet, etcetera."

But buying the hub doesn't automatically mean you'll have 5G speeds on a 4G phone. You'll get faster speeds only if your phone has 802.11ad, which enables WiGig Wi-Fi speeds. If your phone is older and runs only 802.11ac Wi-Fi, you'll end up with a bottleneck where the hub is trying to deliver data faster than your phone can handle.

MWC isn't the last time we'll hear about 5G phones. But you might want to wait until next year before you rush to buy one.
