Foldable Phones: Good, Bad, Caveats

Foldable smartphones are good for people who want a larger screen in a pocketable size, but they come with real compromises in durability, price, and repairability. This article explains what foldables do well, where they fall short, and the caveats you should know before buying one.

How Foldable Phones Work

Instead of a single rigid display, a foldable uses a flexible OLED panel that can bend around a hinge. The screen is made of multiple thin layers, including a plastic substrate (instead of glass) that allows it to flex. The hinge is the critical mechanical part—it must allow the display to fold flat while keeping dust and debris out, and it must survive tens of thousands of folds. Most foldables come in two main designs:

• Book-style (fold inward): Like the Samsung Galaxy Z Fold or Google Pixel Fold—a phone that opens into a small tablet.
• Clamshell (fold horizontally): Like the Samsung Galaxy Z Flip or Motorola Razr—a compact square that opens into a normal phone.

The flexible display is the defining feature, but it is also the source of most durability concerns.

The Good: What Foldables Do Well

The main advantage is screen real estate. A book-style foldable gives you a tablet-sized display that fits in a pocket, which is great for reading, watching video, multitasking with two apps side by side, and working on documents. Clamshell foldables offer a smaller footprint when closed—they fit easily in small pockets or purses—while still giving you a full-size screen when open.

Foldables also enable new multitasking features. Many allow you to run multiple apps simultaneously on the large screen, drag and drop between them, and use the device half-folded as a mini-laptop with the bottom half acting as a virtual keyboard or trackpad. The cover display on book-style foldables lets you check notifications, reply to quick messages, and take selfies without opening the device.

The Bad: Durability and Wear

The most significant drawback is durability. The flexible display is made of plastic, which scratches much more easily than glass. Even with a pre-installed screen protector, many users report visible crease lines and micro-scratches over time. The hinge is also a point of failure—if it gets jammed with dust or sand, or if it wears out, the screen may not open flat or may even crack.

Foldables are not waterproof in the same way as traditional flagships. While some recent models have IPX8 ratings (meaning they can survive submersion in water), they are not dust-resistant. The moving parts of the hinge make it difficult to seal against fine particles, so sand and grit are a real hazard. Dropping a foldable is also riskier—the flexible screen can be damaged by impacts that a glass phone might survive, and the hinge can be bent out of alignment.

Common Problems and Caveats

Beyond durability, there are several caveats to consider:

• The crease: A visible line across the middle of the screen where it folds. It is more noticeable in bright light and when viewing dark content. You may stop noticing it after a while, but it is always there.
• Screen protector issues: Many foldables ship with a pre-installed screen protector that is not meant to be removed. Peeling it off can damage the display. If it bubbles or lifts, you need to have it replaced by the manufacturer.
• Weight and thickness: Even the latest foldables are heavier and thicker than traditional phones. A book-style foldable often weighs over 250 grams (about 9 ounces) and is nearly 14 mm thick when closed.
• Battery life: The large screen consumes more power, and the battery is often split into two halves around the hinge. While batteries have improved, foldables generally have shorter battery life than comparable bar phones.
• App compatibility: Some apps do not scale well to the unusual aspect ratios of foldable screens. You may see letterboxing (black bars) or stretched content, though this is improving.
• Repairability: If the screen or hinge breaks, repairs are expensive—often hundreds of dollars. The flexible display is difficult to replace, and the hinge is a complex assembly.

Cost and Value

Foldables are expensive. Book-style models typically cost $1,500 to $2,000 or more, while clamshell models are slightly cheaper, often around $1,000 to $1,300. That is significantly more than a traditional flagship phone, which usually costs $800 to $1,200. You are paying a premium for the novelty and the engineering. Over time, prices have come down, and there are more budget-friendly options, but they are still not cheap. When comparing value, consider not just the upfront cost but also the higher repair costs and the potential need for a replacement sooner than you would expect from a traditional phone.

How to Choose: Is a Foldable Right for You?

Before buying, ask yourself what you value most. If you prioritize durability, battery life, and a proven design, a traditional bar phone is likely a better choice. If you want a large screen for media and multitasking but also want it to fit in your pocket, a book-style foldable might be worth the trade-offs. If you want a compact device that still has a big screen, a clamshell is a good middle ground.

Consider your lifestyle: do you work in dusty environments, spend time at the beach, or drop your phone often? If so, a foldable may not be the best fit. Also, think about how long you typically keep a phone. If you upgrade every 2-3 years, a foldable might survive, but if you tend to keep phones for 4+ years, the hinge and screen may wear out before you are ready to upgrade.

If you do decide to buy, look for models with high IP ratings (at least IPX8 for water resistance), a sturdy hinge design, and a good warranty. Some manufacturers offer discounted screen repairs for the first year, but read the fine print.

Alternatives to Foldables

If you want a large screen without the foldable trade-offs, consider a traditional large phone (like a “phablet” with a 6.7-inch or larger screen) or a small tablet. You can also use a phone with a desktop mode (like Samsung DeX) to get a tablet-like experience when connected to an external monitor. If you want a compact phone, there are still some small bar phones available, though they are increasingly rare. For those who want the multitasking features, many traditional flagships now offer split-screen and pop-up window modes.

Frequently Asked Questions

Will the crease go away?

No, the crease is a permanent feature of the flexible display. It may become less noticeable over time as the screen “breaks in,” but it will never disappear completely. Some users report that it is less visible with certain screen protectors or when viewing content at certain angles.

Can I remove the pre-installed screen protector?

No, do not remove it. The screen protector is an integral part of the display stack, and removing it can cause the screen to crack or become damaged. If it starts to peel or bubble, contact the manufacturer for a replacement—do not try to fix it yourself.

Are foldables waterproof?

Some are, but not all. Look for an IP rating. IPX8 means the device can be submerged in water, but it does not guarantee protection against dust. IP68 includes dust resistance, but very few foldables have that rating because the hinge makes it difficult to seal against dust.

How long do foldable screens last?

Manufacturers typically rate the hinge for at least 200,000 folds, which is about 100 folds per day for 5 years. However, real-world durability depends on usage, environment, and how well you care for the device. The screen itself can develop dead pixels or lines over time, especially if the device is dropped.

Is the camera as good as on traditional flagships?

Generally, no. Foldables often have slightly older or lower-spec cameras compared to the top traditional flagships of the same year, partly due to space constraints. However, the difference is often small, and many users find the cameras more than adequate. If photography is your top priority, a traditional flagship is usually a better choice.
