Google’s Pixel Fold Can Make Foldable Phones Exciting Again

Commentary: Foldable phones are disappointing, but Google’s Pixel Fold could change that. Here’s how.

Back in 2021 I wrote that foldable phones were disappointing, providing little to no revolution in how we use our phones on a daily basis, beyond the novelty of a screen that bends. They’re perfectly fine. But once you get over the initial fun of the fold, they’re really just another Android phone. The problem is that with less common sizes and aspect ratios being used on today’s foldables, apps and games don’t natively run properly. The audience is small, and developers don’t have the motivation to put in the time, effort and cost to develop their apps for odd shapes and sizes.

But Google might change that soon enough, with a rumored foldable Pixel phone that could appear at Google I/O in May. The company is in a unique spot to address software concerns while creating compelling phone hardware that doesn’t break the bank.

To be clear, I do like foldable phones. I particularly like the larger «book fold» models like the Samsung Galaxy Z Fold 4 and Honor Magic Vs, which transform from a regular-sized phone into an almost tablet-sized device, providing more screen space for videos, games and documents. I remember when I got the first-generation Galaxy Fold and felt genuinely excited at seeing the screen bend in the middle. And I remember the various strangers who would stop and ask to see it when I used it in public — with one bartender so entranced with the demo I gave that he returned the favor with a free beer. Score.

But the software is still where folding phones lag behind. Android is designed primarily for regular candybar smartphones, which are commonly around 6 inches to 6.8 inches in size and have standard aspect ratios like 16:9. In other words, phones like the Galaxy S23 Ultra or Pixel 7 Pro take full advantage of Android, and app developers design their apps for these same form factors. Why? Because they’re the most commonly used sizes, and therefore their apps will be optimized for the widest number of devices.

Android 12L and 13 address some of the sizing issues, but not all apps are optimized and either leave too much blank screen space or must stretch awkwardly to fit the screen. The Galaxy Z Fold 4, for example, has a tall and narrow 23.1:9 aspect ratio on the outside and a more square 21.6:18 aspect for the inner display — two nonstandard sizes that developers need to account for. And that’s just one device.

It’s the same Android fragmentation issue that has plagued the platform since the beginning: Too many different devices means it’s difficult for developers to create for. Apple’s strategy of having fewer display sizes and almost identical aspect ratios has meant it’s typically been the easier platform for developers to work on. But Google has worked hard over the years to make Android an easier field on which to play, and it could do the same for foldables.

So could a folding Pixel phone be just another device for developers to struggle with? Perhaps not. If Google is committed to folding screen technology in its product lineup, then it’s safe to assume that we will see some key updates in Android that are specifically tailored to folding phones and different form factors. I’d like to see software that does a better job of automatically resizing apps, dual-screening when using a large display like the Z Fold 4’s or building more tricks into default apps that take advantage of inner and outer displays.

Moreover, Google will likely work more closely with its key developer partners like Samsung, helping them not only optimize their existing apps for folding devices, but also create entirely new ones that can only be done with phones of this type. These partnerships will be crucial to helping Google create a compelling first-generation foldable, especially since non-folding Pixel phones account for just over 2% of smartphone market share in the US, according to analytics firm StatCounter. By comparison, Samsung has almost 30% share in the US.

Pixel phones tend to offer an excellent Android experience packaged in good hardware that costs hundreds less than flagship iPhone or Galaxy S phones. Google partnerships will be key to getting a Pixel foldable off the ground at an affordable price. A cheaper price is essential to getting a larger audience that would incentivize developers to create more fold-centric apps.

There are a lot of «ifs» and «coulds,» and we don’t know for sure if Google will launch a foldable. We also don’t know whether Google has a strategy in place to encourage adoption by working with software developers. Google will also have to rely on more than just its recognizable name to catapult the category into the big leagues. Let’s not forget that Microsoft’s Surface Duo 2 isn’t exactly ubiquitous, and neither is Samsung’s Galaxy Z Fold.

But I’m remaining hopeful, if only because I need to be. Standard smartphones have become increasingly dull and repetitive. For someone who writes about phones for a living, that’s a problem. Foldables present an opportunity to do things in a different and more exciting way, but it will be up to Google whether or not the category flourishes.

Blade Runner: 18-Rotor «Volocopter» Moving from Concept to Prototype

It may look "nutty" and like a "blender," but the designers say the craft could challenge helicopters

Inventor and physicist Thomas Senkel created an Internet sensation with the October 2011 video of his maiden—and only—test flight of a spidery proof-of-concept 16-rotor helicopter dubbed Multicopter 1. Now the maker of the experimental personal aviation craft, the European start-up e-volo, is back with a revised «volocopter» design that adds two more rotors, a serial hybrid drive and long-term plans for going to 100 percent battery power.

The new design calls for 1.8-meter, 0.5-kilogram carbon-fiber blades, each paired with a motor. They are arrayed around a hub in two concentric circles over a boxy one- or two-person cockpit.

After awarding the volocopter concept a Lindbergh Prize for Innovation in April, Yolanka Wulff, executive director of The Charles A. and Anne Morrow Lindbergh Foundation, admitted the idea of the multi-blade chopper at first seems «nutty.» Looking beyond the novel appearance, however, she says, e-volo’s concept excels in safety, energy efficiency and simplicity, which were the bases of the prize.

All three attributes arrive thanks largely to evolo’s removal of classic helicopter elements. First, the energy-robbing high-mass main rotor, transmission, tail boom and tail rotor are gone. The enormous blades over a normal chopper’s cabin create lift, but their mass creates a high degree of stress and wear on the craft. And the small tail rotor, perched vertically out on a boom behind the cabin, keeps the helicopter’s body from spinning in the opposite direction as the main blades, but it also eats up about 30 percent of a helicopter’s power.

The volocopter’s multiple rotor blades individually would not create the torque that a single large rotor produces, and they offer redundancy for safety. Hypothetically, the volocopter could fly with a few as 12 functioning rotors, as long as those rotors were not all clustered together on one side, says Senkel, the aircraft’s co-inventor and e-volo’s lead construction engineer.

Without the iconic two-prop configuration, the craft would be lighter, making it more fuel efficient and reducing the physical complexity of delivering power to the top and rear blades from a single engine. Nor would the volocopter need an energy-hungry transmission. In fact, «there will be no mechanical connection between the gas engine and the blades,» Senkel says. That means fewer points of energy loss and more redundancy for safety.

E-volo’s design eliminates the dependence on a single source of power to the blades. As a serial-hybrid vehicle, the volocopter would have a gas-fueled engine, in this case an engine capable of generating 50- to 75 kilowatts, typical of ultralight aircraft. Rather than mechanically drive the rotors, the engine would generate power for electric motors as well as charge onboard lithium batteries. Should it fail, the batteries are expected to provide enough backup power so the craft could make a controlled landing.

Whereas helicopters navigate by changing the pitch of the main and tail rotor blades, the volocopter’s maneuverability will depend on changing the speed of individual rotors. Although more complex, it is more precise in principle to control a craft using three to six redundant microcontrollers (in case one or more fails) interpreting instructions from a pilot using a game console–like joystick—instead of rudder pedals, a control stick and a throttle.

Wulff’s first impression about the volocopter’s design is not uncommon. E-volo’s computer-animated promotional videos of a gleaming white, carbon-fiber and fiberglass craft beneath a thatch of blades recall the many-winged would-be flying machines of the late 19th century. This point is not lost on Senkel.

«I understand these skeptical opinions,» he says. «The design concept looks like a blender. But we really are making a safe flying machine.»

That would be progress in itself. Multicopter 1 looked like something from an especially iffy episode of MacGyver, complete with landing gear that involved a silver yoga ball. Senkel rode seated amid all those rotors powered only by lithium batteries. Multicopter 1 generated an average of 20 kilowatts for hovering and was aloft for just a few minutes.

There’s a reason why the experimental craft flew briefly and only once.Senkel describes that first craft as «glued and screwed together.» Seated on the same platform as the spinning blades, he says, «I was aware of the fact that I will be dead, maybe. Besides, we showed that the concept works. What do we win if we fly it twice?» he asks rhetorically.

Other than putting the pilot safely below the blades, the revised volocopter design would operate largely the same as the initial prototype. The design calls for three to six redundant accelerometers and gyroscopes to measure the volocopter’s position and orientation, creating a feedback loop that gives the craft stability and makes it easier to fly, Senkel says.

The volocopter’s revised prototype under construction could debut as soon as next spring. The first production models, available in perhaps three years, are expected to fly for at least an hour at speeds exceeding 100 kilometers per hour and a minimum altitude of about 2,000 meters, still far shy of standard helicopter’s normal operating altitude of about 3,000 meters. «This could change our lives, but I don’t expect anything like that for 10 years,» Senkel adds.

Given that most of the technology needed to build the volocopter is already available, «this idea is fairly easy to realize,» says Carl Kühn, managing director of e-volo partner Smoto GmbH, a company that integrates electric drive systems and related components.

Like Senkel, Kühn has modest short-term expectations despite his repeated emphasis on the standard nature of the technology involved. «I guess that e-volo will have [a prototype] aircraft in three years that can do the job—that it will lift one or two persons from one point to another,» he says.

The biggest immediate limitations appear to be regulatory. For instance, European aviation regulators consider any electrical system greater than 60 volts to be high voltage and regulate such systems more aggressively, Kühn says. As a result, the volocopter will operate below that threshold. The craft will also need to weigh no more than 450 kilograms to remain in the ultralight category, which is likewise subject to fewer government aviation regulations, according to Senkel.

The Lindbergh Foundation’s Wulff says the organization’s judges felt e-volo had «a greater than 50 percent chance of succeeding, or they wouldn’t have given them the innovation award.» Asked if she would line up to fly one someday, she says, «I sure would. It looks very compelling to me.»
