Design, screens and sound

It can be said that folding mobiles are divided into two, those that fold like a book and those that fold like a shell. The OnePlus Open is one of those cool ones, one of those that opens like a book. When deployed, it has a 7.82-inch internal screen with 2K resolution, Refresh rate 120 Hz, LTPO 3.0 technology and Ceramic Guard protection. This screen offers great image quality, as is usually a constant in mobile phones of this brand, with vivid colors, high brightness and contrast, and remarkable smoothness. The 1.0758:1 aspect ratio is comfortable, especially since this type of terminal is designed to be used for hours at a time.

When folded, the OnePlus Open has a 6.31 inch outdoor screen with the same features as the interior, except for a resolution that is 2484 x 1116 pixels and an aspect ratio that is 20:9. This screen allows you to use your phone like a normal smartphone with access to all functions and applications. With this ratio, when the mobile is folded, it does not stand out, it does not appear to be what it really is, it passes discreetly and is appreciated, noticed only by those who notice its thickness.

One thing we’ve been missing from this type of mobile is that it could be supported in a stand mode so that we can support it and view content without having to hold it. Granted, no cell phone of this type has this, but a small tab like the one the Nintendo Switch has would give it extra usability.

In addition, both screens are compatible with Dolby Visionwhich improves the viewing experience with a wider dynamic range.

The design of the OnePlus Open is sleek and minimalist, with a metallic finish and two color options: Emerald Dusk and Midnight Black. The phone is 5.9mm unfolded and 11.9mm folded and weighs 239 grams, making it lighter than other foldable devices. Additionally, it has a side button that doubles as a fingerprint reader and an Alert Slider, a switch that lets you switch between sound modes. It has a rectangular camera module with a logo on the back Hasselblada professional photography brand that works with OnePlus.

The hinge, an element that makes foldable smartphones possible and which can also make your user experience miserable. The OnePlus Open hinge is barely noticeable, we have to look closely to appreciate the crease in the screen and swipe carefully to notice the thickness. The hinge on the OnePlus Open is integrated, doesn’t get in the way and does the job.

We especially mention the quality sound of this terminal. It has multiple “reality” Dolby Atmos speakers. They achieve the sound quality that caught our attention for a smartphone. It highlights the performance that this terminal offers without distorting the quality of the equalization and ensures that it does not distort extreme frequencies.

Performance and battery

As expected, the OnePlus Open has top-notch performance thanks to the Snapdragon 8 Gen 2 processor, Qualcomm’s most powerful chip to date, offering 30% more performance than the Snapdragon 888 and 25% more power consumption. In addition, it has 16 GB of RAM and 512 GB of internal memory, which guarantees excellent fluidity and storage capacity.

OnePlus Open battery is 4,805 mAh, divided into two cells of 3,295 and 1,510 mAh, respectively This battery offers good autonomy, which may vary depending on the use of the phone and screens. According to OnePlus, the phone can last up to 14 hours of mixed use with the internal screen and up to 24 hours with an external screen. In addition, OnePlus Open has a Fast charging 67W SuperVOOCwhich allows you to charge the phone to 100% in about 40 minutes.

Cameras

OnePlus Open has a rear camera system consisting of three sensors: main, telephoto and ultra-wide. The main sensor is Sony LYT-T808 48MP, which has an innovative two-layer transistor architecture that captures more light and reduces noise. This sensor has f/1.7 aperture, 1.12 µm pixel size and optical image stabilization (OIS). The telephoto lens is a 64MP OmniVision OV64B that has 3x optical zoom, 6x lossless zoom, f/2.6 aperture, 0.7µm pixel size and OIS. The ultra-wide-angle sensor is a 48MP Sony IMX581 that has a 114º field of view, f/2.2 aperture, and autofocus (AF).

OnePlus Open cameras offer very high image quality with a good level of detail, wide dynamic range, true colors and accurate white balance. In addition, they have a night mode that improves photos in low light, a portrait mode that creates a natural bokeh effect and a macro mode that lets you get closer to your subjects. The cameras can also record video in 8K resolution at 30 fps or 4K at 60 fps, with good stabilization and stereo sound.

OnePlus Open has two front cameras, one on the outer screen and one on the inner screen. The external camera has a resolution of 32 MP and an aperture of f/2.4, while the internal camera has a resolution of 20 MP and an aperture of f/2.2. Both cameras offer good image quality for selfies with good levels of detail, good dynamic range and natural colors. They also have a portrait mode that creates a subtle bokeh effect and a beauty mode that allows you to adjust various facial parameters. One of the big advantages of these phones is of course selfies, you can finally see yourself as if you were looking in a mirror and take a photo instantly. You will know exactly how you are posing and will be able to take a photo with the best quality camera.

Software

The OnePlus Open software is OxygenOS 13.2based Android 13. This operating system has a clean and fluid interface with a design adapted for foldable screens. In addition, it has several exclusive features such as Open Canvas, which allows you to use several applications on the internal screen at the same time with a system of gestures to switch between them, focus on them or share them. It also features a desktop mode that allows you to connect the phone to an external monitor and use it as a computer, with a wireless keyboard and mouse.

In rare cases, we have noticed that some apps are misconfigured if you use them with a single screen and switch to dual. Sometimes it is necessary to close and reopen the application.

Conclusion

The OnePlus Open is a foldable phone that excels in design, screens, cameras and performance. It is a device that offers a great user experience, both as a smartphone and as a tablet, with excellent image and sound quality, impressive performance and fluidity, and cameras that take high-quality photos and videos.
