Foldable phones are no longer a futuristic dream. They are real, practical, and quickly becoming part of daily life. Among the many options, two models stand out for tech fans and regular users alike: the Oppo Find N3 Flip and the OnePlus Open. Both come from respected brands with a reputation for innovation and quality. But which one should you choose? Making the right decision is not easy, especially when both phones offer exciting features, unique designs, and powerful hardware. In this in-depth review, you’ll discover how these two foldables compare, where each one shines, and what you need to consider before buying.
Oppo Find N3 Flip: Compact Powerhouse
The Oppo Find N3 Flip is the third generation of Oppo’s clamshell-style foldable phones. It refines the formula with better materials, improved cameras, and a more robust hinge. Its design takes inspiration from the classic flip phone, but with all the modern features you expect from a premium smartphone.
Design And Build
The Oppo Find N3 Flip keeps the familiar clamshell form factor, making it pocket-friendly and easy to carry. It weighs around 198 grams and feels solid in hand, thanks to its aluminum frame and Gorilla Glass Victus on the cover display. When closed, it is compact and stylish; open it, and you get a tall 6.8-inch AMOLED display with minimal crease.
Oppo has focused on durability. The N3 Flip’s hinge system is smoother and more robust than previous models. It is tested for over 400,000 folds, so you don’t have to worry about regular use. The exterior cover screen (3. 26-inch AMOLED) is vertical, which helps with quick notifications and even using some apps without opening the phone.
Display Quality
Inside, the main display is a 6.8-inch FHD+ AMOLED with a 120Hz refresh rate. It’s bright (up to 1,200 nits), sharp, and colorful. The crease is less noticeable than in older foldables, and touch response is smooth for gaming or scrolling. The outer screen is also AMOLED, so colors and contrast stay vibrant even when the phone is closed.
Performance
Powered by the MediaTek Dimensity 9200 chipset, the Find N3 Flip handles most tasks with ease. You get 12GB of RAM and up to 512GB of storage. It’s fast for daily use, multitasking, and even demanding games. While the chipset is not the absolute top (like Snapdragon 8 Gen 2), it is one of the best from MediaTek and holds its own in real-world use.
Camera System
One of the biggest upgrades is the camera. The N3 Flip features a triple camera system on the back, a rare setup for clamshell foldables:
- 50MP main sensor (Sony IMX890)
- 48MP ultra-wide lens
- 32MP telephoto (2x optical zoom)
Photos are clear, with natural colors and good dynamic range. Low-light performance is impressive for a foldable. The telephoto lens allows for portrait shots with more depth. For selfies, the 32MP front camera is sharp, but you can also use the rear cameras for even better quality thanks to the cover screen.
Battery Life And Charging
The 4,300mAh battery is larger than most flip phones. With moderate use, it easily lasts a full day. Fast charging (44W SuperVOOC) means you can get to 50% in about 23 minutes. There’s no wireless charging, which might disappoint some users.
Software Experience
Oppo uses ColorOS 13 based on Android 13. The interface is smooth and customizable, with special features for the foldable display. For example, you can run split-screen apps or use the cover screen for quick replies and camera previews. Oppo promises three years of major updates and four years of security patches.
Unique Insights
Most new users overlook how useful the cover screen is. You can check notifications, control music, and even run full apps like messaging or maps without opening the phone. This saves battery and makes the phone even more convenient.
Another hidden benefit is the hinge’s FlexForm mode. You can partially fold the phone, set it on a table, and use it for hands-free video calls or selfies—a small feature that quickly becomes essential.
Oneplus Open: The Book-style Challenger
The OnePlus Open is the first foldable from OnePlus, but it enters the market with confidence. Unlike the N3 Flip, this is a book-style foldable that opens into a small tablet. It aims to combine phone portability with the productivity of a larger screen.
Design And Build
The OnePlus Open is slim for its category. Closed, it’s about 11. 7mm thick and weighs around 239 grams. The outer shell uses a mix of glass and aluminum for a premium feel. OnePlus claims the hinge is tested for 1 million folds, showing their focus on long-term reliability.
What stands out is how thin the device is when open—just 5.8mm. This makes it easy to hold as a tablet, and the hinge almost disappears into the design. The phone comes in two colors: Voyager Black and Emerald Dusk.
Display Quality
The Open features two high-end AMOLED displays:
- 6.31-inch cover display (2K, 120Hz)
- 7.82-inch inner display (2K, 120Hz, LTPO 3.0)
Both screens are sharp, bright (up to 2,800 nits peak), and support HDR10+. The main screen is nearly crease-free, thanks to the new “Flexion Hinge” design. The outer display’s 20:9 aspect ratio feels natural, unlike some foldables that are too narrow when closed.
Performance
OnePlus doesn’t hold back on performance. The Open runs on the Qualcomm Snapdragon 8 Gen 2 chip, paired with 16GB RAM and up to 512GB storage. This is flagship-level hardware, so you can expect smooth multitasking, gaming, and fast app launches. It’s one of the fastest foldables on the market.
Camera System
The camera system is a partnership with Hasselblad, known for color science and professional results. The triple camera setup includes:
- 48MP main (Sony LYTIA-T808)
- 48MP ultra-wide
- 64MP telephoto (3x optical, up to 120x digital)
Photos are sharp, with rich colors and good detail even in low light. The telephoto lens is especially strong for zoom shots. Selfies can be taken with the 20MP inner camera or the 32MP outer camera, and you can use the main cameras for higher-quality selfies by folding the phone.
Battery Life And Charging
The 4,805mAh battery is above average for a foldable. With heavy use, it still lasts a full day. Fast charging (67W SuperVOOC) brings the battery to 100% in about 40 minutes. However, there’s no wireless charging—OnePlus says this was to keep the device thin and light.
Software Experience
The Open runs OxygenOS 13.2 based on Android 13. OnePlus includes multitasking features like split-screen and floating windows, making good use of the larger inner display. You can drag and drop between apps or run up to three apps side-by-side. OnePlus promises four years of major Android updates and five years of security updates.
Unique Insights
Many overlook how the Open’s outer display feels like a normal phone. Some foldables have awkward sizes when closed, but the Open is easy to use one-handed. Another point: the multitasking features are not just for techies—drag-and-drop works with photos, text, and files, making daily tasks much faster.

| Price (approx.) | $1,000–$1,200 | $1,699–$1,799 |
Form Factor: Flip Vs Book
- The Oppo Find N3 Flip is for those who want a compact phone that fits in any pocket but opens up to a regular smartphone size.
- The OnePlus Open is for users who want a bigger screen for reading, watching videos, or multitasking, but don’t want to carry a tablet.
Performance And Usability
The OnePlus Open has a clear edge in raw power and multitasking, thanks to its Snapdragon 8 Gen 2 and more RAM. The Open is better for heavy users, gamers, or anyone who wants to replace both phone and tablet with one device.
On the other hand, the N3 Flip is more than enough for daily use, social media, and even photography. Its smaller size means it’s easier to use one-handed and less bulky in a purse or pocket.
Cameras: Quality And Versatility
Both phones break the mold for foldable cameras. The Oppo Find N3 Flip is the only major flip phone with a triple rear camera, making it a standout for photography. The OnePlus Open’s Hasselblad partnership and powerful zoom give it a slight advantage for serious photographers, especially in zoom or wide shots.
Battery Life And Charging
Foldables are known for weaker battery life, but both Oppo and OnePlus have improved this. The Open’s larger battery and faster charging win here, but the N3 Flip is no slouch and will last a full day for most users.
Software And Updates
Both brands offer strong update policies. OnePlus promises slightly longer support, which may matter if you plan to keep your device for several years.
Price And Value
The N3 Flip is noticeably cheaper. If you want a foldable phone for under $1,200, it’s an excellent choice. The Open is more expensive but justifies the price with a bigger screen, better cameras, and flagship hardware.
Real-world Experience: What Matters Most
When choosing between these two, think about how you use your phone every day:
- Do you value pocketability and a classic flip style? The Oppo Find N3 Flip is hard to beat.
- Need a device that works as both a phone and a small tablet? The OnePlus Open’s big screen will make you more productive.
- Are you a photography fan? Both phones are strong, but the Open’s zoom and Hasselblad tuning stand out.
- Want the latest hardware and fastest performance? The Open wins here, but for regular use, the N3 Flip is still excellent.
Many buyers forget to consider ergonomics. The N3 Flip is easier to use one-handed and less likely to slip out of your grip. The Open, while slim, needs two hands when open and is heavier in the pocket. Another point: app support for foldables is still improving. Not all apps take full advantage of the Open’s big screen, but both Oppo and OnePlus are working with developers to fix this.

Durability And Longevity
Foldable phones have a reputation for being fragile, but both Oppo and OnePlus have worked hard to fix this. The N3 Flip’s hinge is rated for 400,000 folds, while the Open claims 1 million. In real life, this means you can use the phone for years without worrying about the hinge wearing out.
Both phones have glass covers, but neither offers full waterproofing like the best traditional phones. The Open has an IPX4 rating (splash resistant), while the N3 Flip has no official rating. You still need to be careful with water and dust.
Software Ecosystem And Features
Both phones run Android 13 with their own custom skins. The Open’s multitasking is better for power users, letting you have multiple apps on screen and drag-and-drop between them. The N3 Flip focuses on making the cover screen more useful, letting you reply to messages or use navigation without opening the phone.
Oppo’s ColorOS and OnePlus’ OxygenOS are both smooth, but they feel different. OxygenOS is closer to “stock” Android and is more straightforward, while ColorOS is more customizable with extra features. If you already own an Oppo or OnePlus device, you’ll find the transition easier.

Accessories And Ecosystem
Neither phone comes with many accessories in the box. You get a charger and cable, but cases and screen protectors must be bought separately. Both brands offer official cases, but third-party options are still limited for foldables.
OnePlus has a stronger ecosystem if you already use their earbuds or smartwatches. Oppo’s ecosystem is growing, but integration is not as tight.
Software Updates And Support
Long-term support is becoming more important as phones get more expensive. OnePlus promises four years of Android updates and five years of security patches. Oppo offers three years of Android updates and four years of patches. This means the Open will stay up-to-date for longer.
