Why You Won’t Be Buying a Rollable Phone Anytime Soon

Shapeshifting concepts from Motorola and Samsung likely won’t turn into real products for quite some time.

Imagine if your phone or tablet could change the size of its screen depending on what you’re doing? That’s the future Motorola and Samsung envision, as both companies showcased concept devices capable of extending or shrinking their displays with the press of a button.

Motorola flaunted its concept at Mobile World Congress this week, while Samsung exhibited a slew of shapeshifting prototypes at CES in January. Such concepts prove phone makers are thinking about the next evolution of personal devices beyond today’s static touchscreens. They’re even looking beyond foldable phones, which have only been widely available for a little more than three years.

But as eye-catching as these concepts are, it’ll likely be a long time before you’re carrying one around. High prices, engineering and durability challenges and a lack of compelling use cases will likely mean these concepts won’t turn into real products anytime soon. And if they do, there are still good reasons why you should wait before buying one.

Rollable phones are eye-catching

Conceptual devices with expandable screens have surfaced before, but they’ve garnered attention again this week at Mobile World Congress thanks to Motorola and its parent company Lenovo.

Motorola showcased its prototype palm-sized phone that extends with the double press of a button. And even better, the screen automatically unfurls when using certain apps like YouTube, according to my colleague Andrew Lanxon, who got to see the device at the conference. The phone may also switch between small and large mode depending on what you’re doing within an app. For example, the phone may stay tiny when you’re scrolling through your inbox, but it could automatically expand as you compose an email, Lanxon writes.

When the device is in its compact form, the display wraps around the bottom of the device to provide a secondary screen on the back of the phone. I can’t think of many other reasons to use this extra screen other than as a viewfinder for taking selfies with the rear camera, as Lanxon did during his demo. Regardless, it’s intriguing to see how Motorola is thinking about putting that technology to use.

Even though phones with rollable screens are in their infancy, they could present some notable advantages over today’s foldables, according to Ross Young, CEO and co-founder of Display Supply Chain Consultants. The crease may be smaller since it would be located at the edge of the device rather than in the center, he said via email. Rollable phones will also likely be thinner than current devices like the Galaxy Z Fold 4, which resembles two phones stacked on top of one another when folded.

But those benefits will probably result in additional engineering challenges. The motors and sliding mechanisms likely require more power consumption, says Young.

«Some brands told us there is a lot of work still to be done,» he said.

It’s not the first time Motorola has shown a concept like this; the phone maker also showcased the tech at Lenovo’s Tech World conference last year. But its arrival at MWC underscores Motorola’s ambitions in this area.

Motorola isn’t the only company interested in making phones with screens that can roll, slide and expand. Nearly two months ago, Samsung exhibited its own vision for what futuristic phones and tablets could look like. The star of the show was the Flex Hybrid concept, which looks like a notebook when closed but can switch between 10.5-inch and 12.4-inch screen sizes when opened.

LG also made a splash with the rollable phone concept it teased at CES 2021, although the company shut down its mobile phone business shortly thereafter. Chinese tech giant Oppo has developed a rollable phone concept with a 6.7-inch screen that transforms into a 7.4-inch tablet-sized display.

At the same time, foldable phones — which are generally considered to be the precursor for future rollable devices — still only account for a sliver of the overall smartphone market. Foldable phones are estimated to have accounted for just 1.1% of smartphone shipments in 2022 and are expected to make up 2.8% in 2026, according to International Data Corporation. But that hasn’t stopped phone makers from looking ahead.

«They’ve got to keep innovating to differentiate,» said Brad Akyuz, executive director and mobile analyst at NPD Group. «That’s the only way they can just get ahead of the competition.»

But don’t count on buying one anytime soon

The word «concept» is crucial; these devices aren’t products. Instead, they’re proofs of concept meant to illustrate the direction these companies may take when developing future smartphones. That means we don’t know when rollable phones from Motorola, Samsung or other device makers will launch, if ever.

The foldable phone market could serve as a blueprint. Samsung demonstrated flexible display technology as far back as 2013, but it didn’t release its first phone that could fold in half until 2019.

Whether a rollable phone arrives in the near term or not, analysts believe it’ll take several years for the devices to become a regular fixture in the tech world. Akyuz pegs that at around three to four years, while Bill Menezes, a director for market researcher Gartner covering the telecoms industry, estimates three to six years.

There are a variety of reasons why, all of which mirror the challenges that the foldable phone industry is going through. Prices need to be affordable, and phones must be durable enough to withstand everyday use without concern.

They should also offer compelling features that significantly improve the way you use your mobile device to make them worthwhile. Even though today’s foldables have different designs that make our phones more compact when closed, the overall experience is the same as that of using a standard phone. Samsung is trying to address this with a feature called Flex Mode, which divides compatible apps across the top and bottom portions of the display when folded halfway. But this feels more like an optimization than a brand new way to use your phone.

«A foldable phone really isn’t that much different than a flat phone concept,» said Menezes. «Once you open it, you’re still scrolling through to get to different applications, or different screens or tabs.»

Even if a company like Motorola or Samsung does release a rollable phone in the near future, you probably shouldn’t buy it. First-generation products can be expensive, damage-prone and not as polished as later iterations.

Take the Galaxy Fold from 2019, for example, which Samsung postponed launching after a small number of reviewers reported issues with the display. That phone was also priced at $1,980, while the much-improved Galaxy Z Fold 4, which just launched in August, starts at $1,800. Samsung’s smaller foldable, the Galaxy Z Flip, has also matured; the first version had a tiny screen that barely felt useful and lacked 5G.

Now, more than three years after the Galaxy Fold’s launch, demand for foldable devices is starting to accelerate. Even though IDC’s report suggests foldables only account for a fraction of the smartphone market, shipments are estimated to have grown by 66.6% in 2022 compared to 2021. NPD Group’s Connected Intelligence Mobility Survey also suggests interest is growing. While 51% of survey respondents said they were not likely at all to buy a foldable phone in 2019, only 36% said the same in 2022, according to data from the survey shared with CNET.

«I think this is the future, I don’t think we can deny that,» Akyuz said. «But as we’ve seen with the foldable category, it’s just going to take some time to get there.»

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
