I’ve been staring at a crease for the better part of a week. Not a metaphorical one—a literal, physical line running down the center of a $1,800 device that’s supposed to represent the next evolution of mobile engineering. The sales pitch is seductive: a tablet that folds into a phone, a device that defies physics, a glimpse of the future you can hold today. But after living with one, I’m left with a more grounded question: are foldable phones actually ready for people who just need a phone that works, or are we all unwitting participants in a very expensive public beta?
I’m Marcus Huang, and I’ve spent over a decade tearing down gadgets and questioning the narratives that tech companies spoon-feed us. My skepticism isn’t born from a hatred of progress; it’s forged in the reality of shattered screens, lagging software, and promises that evaporate the moment a new model drops. Foldables are the most ambitious hardware experiment since the smartphone itself, but ambition doesn’t pay your repair bill.
The Crease Is the Elephant in the Room
Let’s start with the most obvious, unavoidable flaw: the crease. Every manufacturer claims their latest iteration has a “less noticeable” crease. Samsung’s marketing materials for the Galaxy Z Fold series practically whisper that it’s “almost invisible.” That’s a lie by omission. Run your finger over the center of the display, and you feel a divot. View the screen at any angle other than dead-on, and light catches the undulating plastic like a scar on polished glass.
I’ve used the Galaxy Z Fold 5 and the OnePlus Open extensively. Both have creases you can feel and see. The argument from enthusiasts is that you “get used to it.” That’s a cop-out. You don’t get used to a scratch on your glasses; you learn to ignore it because the alternative is paying for new lenses. With a foldable, you’re ignoring a fundamental design compromise that sits directly in your field of view every time you unfold the device—which, if you’re using it as intended, is dozens of times a day.
The crease isn’t just cosmetic. It’s a structural weak point. The ultra-thin glass (UTG) layer and the plastic screen protector on top are constantly flexing at that exact line. Samsung’s own warranty guidelines warn against pressing hard on the screen or removing the pre-installed protector, which feels like an admission that the materials are fragile. I’ve seen enough reports of screens spontaneously cracking along the crease—even without drops—to know this isn’t a solved problem. It’s a tolerated one.
Durability: Anecdotes vs. Engineering
Foldable makers love to tout lab tests. “Rated for 200,000 folds,” they say, which translates to roughly five years of use if you open the phone 100 times a day. But lab tests are pristine. They don’t account for pocket lint, beach sand, or the tiny particles of everyday life that can worm their way under the screen protector and press into the soft plastic display when you close the phone. I’ve seen a grain of sand leave a permanent dimple on a foldable screen. Try getting that covered under warranty.
Dust resistance is the quiet killer here. Most foldables now boast IPX8 water resistance—the “X” means no dust rating. That’s not an oversight; it’s a physical limitation of the hinge mechanism. The complex gear-and-sweeper system inside a modern foldable hinge is designed to keep larger particles out, but fine dust is a relentless adversary. Over months of use, you might hear a faint grinding sound when unfolding. That’s the hinge accumulating debris. Eventually, it can affect the smoothness of the fold or even damage the flexible display from behind.
Then there’s the battery. Foldables pack two separate cells connected by a ribbon cable that flexes with every open and close. That cable is a single point of failure. I’ve spoken to repair technicians who’ve seen foldables come in with perfectly intact screens but no power—because that flex cable wore out. It’s a repair that often requires a full teardown, and good luck finding a local shop willing to touch it.
Software That’s Still Playing Catch-Up
Even if the hardware were flawless, the software experience on foldables remains a patchwork of compromises. Android’s large-screen support has improved dramatically since the early days of the Galaxy Fold, but app developers are slow to adapt. Open Instagram on a book-style foldable, and you’re often greeted with a stretched phone interface or black bars. Twitter (I refuse to call it X) sometimes loads in a weird split-view that cuts off content. These aren’t niche apps; they’re daily drivers for millions of people.
Multitasking is the foldable’s killer feature, but it’s also a source of constant friction. Dragging and dropping between apps works about 70% of the time. The other 30%, you’re fighting with the interface, wondering why a simple text selection won’t copy. Samsung’s One UI is the most polished foldable software skin, but it’s still layered on top of Android’s inherent limitations. You can have three apps open at once, but good luck getting them all to resize properly without one crashing or freezing.
Then there’s the aspect ratio problem. Unfolded, most book-style foldables have a nearly square screen. That’s great for reading documents but terrible for watching video, where you get massive black bars that effectively reduce the viewable area to the size of a regular slab phone. You’re carrying a device twice as thick and heavy for a video experience that’s no better—and sometimes worse—than a standard flagship. The OnePlus Open tries to solve this with a wider cover display, but then you’re left with a chunky, awkward phone when closed.
The Price of Early Adoption
Let’s talk about the elephant in the room: cost. Foldables start at around $1,000 for a clamshell like the Motorola Razr and quickly climb to $1,800 for a flagship book-style device. For that money, you could buy an iPhone 15 Pro Max and an iPad Air, with cash left over. Or a top-tier traditional Android phone and a decent laptop. The value proposition only makes sense if a foldable truly replaces two devices, but in practice, it doesn’t.
The cover screen on a book-style foldable is too narrow for comfortable typing. The inner screen is too fragile to use as a primary display in many environments. You end up carrying a device that’s compromised in both modes. The clamshell foldables like the Galaxy Z Flip are more honest—they’re just regular phones that fold in half. But you’re still paying a premium for a smaller battery, inferior cameras, and a screen that feels like soft plastic compared to the glass on a $400 mid-ranger.
Repair costs are the hidden tax. A cracked inner screen on a Galaxy Z Fold 5 can cost over $500 to replace, even with Samsung Care+. Without insurance, you’re looking at a bill that’s more than half the price of a new phone. And because the hinge and screen are so tightly integrated, a simple drop that damages the hinge can necessitate a full screen replacement. These aren’t durable goods; they’re luxury items with the fragility of a Fabergé egg.
Who Are These Actually For?
I’m not saying foldables have no audience. There’s a specific user who genuinely benefits: the hardcore multitasker who needs to run two full-size apps side-by-side on the go and is willing to baby their device. Think stock traders, field researchers reviewing documents, or someone who lives in their email and calendar. For that narrow slice of users, the trade-offs might be worth it.
But the marketing doesn’t target that niche. It targets everyone. Samsung’s ads show young professionals unfolding their phones at rooftop parties, snapping photos, and looking effortlessly cool. The implication is that this is the next logical step after a slab phone—a status symbol of technological progress. That’s misleading. For the average person who drops their phone occasionally, shoves it in a pocket with keys, or just wants a reliable device that lasts three years, a foldable is a liability.
I’ve handed foldables to non-tech friends. Their first reaction is always wonder. Their second reaction, after five minutes of use, is “I’d break this in a week.” They’re not wrong. The anxiety of unfolding a $1,800 device in a crowded subway or near a sandy beach is real. You shouldn’t have to think about your phone’s survival as a daily consideration.
The Hinge: A Marvel and a Menace
The hinge is the soul of a foldable phone, and it’s also its most vulnerable organ. Manufacturers have poured millions into R&D, creating complex gear systems that allow the screen to fold flat without pinching. Samsung’s “Flex Hinge” and Google’s “fluid friction hinge” are genuinely impressive feats of micro-engineering. But they’re also the primary entry point for debris and the first component to fail under stress.
I’ve disassembled a few broken foldables, and the inside of a hinge after a year of use is a graveyard of dust, lint, and tiny metal shavings from the hinge’s own self-destruction. The brushes that are supposed to sweep debris away eventually get clogged. The gears wear down. The satisfying snap of a new hinge becomes a gritty, uneven motion. This isn’t a hypothetical; it’s a predictable failure mode that repair shops are seeing with increasing frequency.
Water resistance is another half-truth. IPX8 means the phone can survive a dunk in fresh water, but the hinge is still a mechanical entry point. Salt water, chlorinated pool water, or even soapy water can accelerate corrosion and strip lubricants. I’ve seen foldables that survived a brief rainstorm only to develop a grinding hinge weeks later because moisture lingered inside and caused slow corrosion. A traditional slab phone with an IP68 rating is simply tougher in real-world conditions.
The Battery Life Conundrum
Foldables pack two batteries, but that doesn’t mean double the endurance. The large inner screen is a power hog, and the device’s software often encourages you to use it. Unfold your phone to check a notification, and you’re suddenly powering a 7.6-inch display at high brightness. Do that a few dozen times a day, and your battery life plummets below that of a standard flagship with a single, more efficient panel.
Charging is another pain point. Most foldables support 25W to 45W wired charging, which is adequate but not class-leading. Wireless charging is often slower than on slab phones due to the dual-battery design and the need to align coils across a folding body. If you’re a heavy user, you’ll find yourself tethered to a charger more often than you’d like, which defeats the purpose of having a device that’s supposed to be your all-in-one mobile powerhouse.
Battery degradation is accelerated by heat, and foldables run hot. The compact folded state traps heat, and the large unfolded screen can generate significant warmth during gaming or video calls. Over a year or two, you’ll notice the battery capacity dropping faster than on a traditional phone. Since most foldables don’t have easily replaceable batteries, you’re looking at a costly service or an early upgrade.
Cameras: The Compromise You Don’t See Coming
Foldable makers love to tout their camera specs, but physics is undefeated. To keep the device thin when folded, the camera sensors have to be smaller than those in a dedicated flagship slab phone. The Galaxy Z Fold 5 uses sensors that are a generation behind the Galaxy S23 Ultra. The Pixel Fold’s cameras are good but not on par with the Pixel 8 Pro. You’re paying a premium for a phone that takes worse photos than a cheaper, non-folding alternative from the same company.
The form factor also introduces practical shooting problems. Unfolded, the device is awkward to hold steady for a photo. Folded, you’re using a tiny cover screen as a viewfinder, which makes framing shots clumsy. The clamshell designs are better here because they mimic a traditional phone when open, but you’re still getting mid-range camera hardware in a flagship-priced device.
The Software Update Gamble
Foldables require specialized software optimization that goes beyond standard Android updates. When a new version of Android drops, manufacturers must adapt it for the folding form factor, which takes extra time. Samsung has been relatively good about updates, but other brands have left users waiting months for features that slab phones get on day one. And when a foldable is three years old, will the manufacturer still prioritize optimizing its niche interface, or will you be stuck with a buggy, abandoned experience?
App developers are the wild card. Even if the OS is updated, third-party apps need to support the foldable’s various screen modes. Many developers simply don’t bother, because foldables represent a tiny fraction of the market. Using a foldable often means accepting that your favorite apps will look broken or awkward for the foreseeable future.
Frequently Asked Questions
Are foldable phones durable enough for daily use?
For careful users who don’t expose their phones to dust, sand, or frequent drops, a foldable can survive daily use. However, the inner screen is far more delicate than traditional glass, and the hinge mechanism is a long-term failure point. If your daily routine includes outdoor activities, manual work, or you simply tend to be clumsy with your phone, a foldable is a risky investment. The technology has improved, but it hasn’t reached the toughness of a standard smartphone.
Is the crease on foldable screens really a problem?
Yes, for most people. While you can learn to ignore the crease visually, it remains a tactile distraction every time you swipe across the center of the screen. More importantly, the crease is a structural vulnerability where the screen is most likely to crack or develop dead pixels over time. It’s a constant reminder that you’re using a first-generation concept, not a refined product.
Do foldable phones offer good value for money?
For the vast majority of users, no. A foldable phone costs significantly more than a flagship slab phone while compromising on durability, camera quality, and battery life. The only real advantage is a larger screen in a pocketable form factor. Unless you have a specific, daily need for a tablet-sized screen on the go and are willing to accept the trade-offs, you’re better off with a traditional phone and a separate tablet.
How long will a foldable phone last before it breaks?
Manufacturers claim their hinges are rated for 200,000 folds, which equates to over five years of use at 100 folds per day. In reality, the screen protector often starts peeling at the crease within 6-12 months, and dust ingress can cause hinge problems within the first year. Many users report needing a screen replacement or experiencing hinge issues within 18 months. The devices are not built to last as long as a traditional smartphone.
Foldable phones are a remarkable engineering achievement, but they’re not ready for the mainstream. They’re expensive prototypes that ask you to pay a premium for the privilege of testing immature technology. Until the crease is truly invisible, the hinge is dust-proof, and the price comes down to earth, I’ll keep my SIM card in a slab phone that I don’t have to baby. The future can wait.
