The OnePlus Open is frequently lauded for its thoughtful and practical design. It's often described as being surprisingly thin and light for a foldable, making it more comfortable to hold and use compared to some of its rivals. The cover screen is particularly well-received for its more traditional smartphone-like aspect ratio, making it feel natural to use without needing to unfold the device.

The inner, folding display is consistently highlighted for its large size and immersive quality. The crease, a common concern with foldable phones, is often described as being minimal and less noticeable than on competing devices, contributing to a more seamless viewing experience for media and multitasking.

Performance is another strong suit, with users reporting a smooth and responsive experience when navigating the interface, running applications, and even engaging in demanding tasks. The software is generally praised for being clean and efficient.

Battery life on the OnePlus Open is often cited as being impressive for a foldable, comfortably lasting through a full day for many users. The inclusion of incredibly fast wired charging is a significant convenience, allowing for quick power top-ups.

The camera system, often co-developed with Hasselblad, is generally considered versatile and capable, delivering good quality photos in various lighting conditions. The main sensor tends to perform well, capturing detailed and vibrant images.

Multitasking on the larger inner display is frequently mentioned as being intuitive and efficient, allowing users to run multiple applications simultaneously with ease.

However, some reviews do point out potential drawbacks:

• The durability rating for water and dust resistance might not be as robust as some competitors.
• While the main camera is strong, the ultrawide and telephoto lenses might not always offer the same level of performance.
• The absence of wireless charging is a feature some users might miss.

Overall, the OnePlus Open is widely considered a premium foldable device that gets many things right. Its comfortable design, excellent displays, strong performance, impressive battery life with fast charging, and capable cameras make it a strong contender and a compelling alternative in the foldable market.
