Design and Display

The OnePlus Open has a unique design. It shares the same design language as the flagship series of this year the OnePlus 11. The back of the foldable has a huge circular camera module which consists of the triple-camera setup. The triple camera setup is triangular and is on the left side of the circle. On the right side, there is a prominent capital “H” marking, signifying the collaboration with Hasselblad. Interestingly, the flash is not integrated within the camera module; instead, it is positioned in the top left corner.

It is available in two colour options; Emerald Dusk and Voyager Black. The Emerald Dusk colour option has a glass back with a matte finish which has a thickness of 11.7mm when closed. The Voyager Black option has a vegan leather finish which feels very premium and has a thickness of 11.9mm when opened. The frame is made up of aluminium which has a shiny finish.

The hinge on the OnePlus Open is one of the best available in foldable smartphones. It has a zero friction gapless design which helps keep dust and other particles out protecting the inner main screen. The hinge is very rigid and can make the smartphone stand at various angles when opened. It also has a snap when open or closed.

The hinge is made up of titanium alloy, carbon fibre and cobalt molybdenum alloy. OnePlus says that it has certified folds of up to 1,000,000 folds. The hinge leaves a minimal crease which cannot be seen at a glance.

The OnePlus Open has an alert slider like the older models of OnePlus. On the display side, the cover screen has curved edges and a centred hole-punch camera cutout. The main screen when opened has a hole-punch cutout on the top left side of the screen. The cover display is not narrow like other foldable smartphones. The overall thickness is not that much so when folded the smartphone feels like other smartphones.

The OnePlus Open display is also really good. The main display when unfolded makes it a mini table which measures 7.82 inches. It has a resolution of 2,440 x 2,268 pixels, which is also called a 2K display, with 426 ppi pixel density.

It has a wider aspect ratio of 1.0758:1 and a dynamic refresh rate of 1 to 120 Hz. The display technology used is called Flexi-fluid AMOLED with LTPO 3.0. It can reach a typical brightness of 1,400 nits and a maximum brightness of 2,800 nits which can be useful in bright-lit outdoor conditions. It supports various colour profiles like sRGB and DCI-P3 and 10-bit colour depth. It also has a touch response of up to 240 Hz.

The cover screen of the OnePlus Open measures 6.31 inches, which is roughly in line with the standard size of regular smartphones, as opposed to the narrower form factor seen in other foldable devices.

It has a resolution of 2,484 x 1,116 pixels, which is also a 2K, with a pixel density of 431 ppi. It also has a dynamic refresh rate from 10 to 120 Hz and uses Super Fluid AMOLED with LTPO 3.0 technology. It has a typical brightness of 1,400 nits and can peak at 2,800 nits.

Its octa-core CPU configuration has one Cortex-X3 core clocked at 3.2 GHz, two Cortex-A715 cores at 2.8 GHz, two Cortex-A710 cores at 2.8 GHz, and three Cortex-A510 cores at 2.0 GHz.

For cooling the OnePlus Open uses cross-channel thermal conductivity. It has a sheet of ultra-conductive graphene which spreads the heat. For example, if one side of the phone is heated then the graphene sheet transfers the heat to the other side for proper heat distribution.

OnePlus has also up the software experience on the OnePlus Open. It is also set to get 4 years of OS upgrades. The software experience is enhanced with new features such as a dual split screen with fast focus and up to 3 windows for multitasking.

However, the 120X digital zoom pictures are not that detailed for human subjects but for patterns and objects, it can do some post-processing for somewhat detailed images. It also includes a 48MP Sony IMX581 ultra-wide sensor with a wide 114° field of view for ultra-wide shots.

As for pricing the OnePlus Open can be expected around Rs 244,000 for the available 16/512GB option.


The OnePlus Open is a good foldable smartphone. As the first generation of foldable smartphone OnePlus surely has done a really good job. There are a few flaws that OnePlus can improve in the second generation of the foldable such as the water and dust resistance.

The OnePlus Open boasts a slim profile, which is a positive feature. However, its slimness comes at the expense of a lack of wireless charging capability. While the software experience is generally excellent, there are occasional instances of lag.

The base configuration with 16GB of RAM and 512GB of storage aligns well with OnePlus’ understanding that a foldable device requires substantial processing power. Nevertheless, it would be advantageous to offer at least one more storage option, such as a base model with 256 GB, which is a common choice in the flagship category.

Even though there is a lot to improve, the battery, camera and display are some of the key features of the OnePlus Open. It offers great value for money in terms of specs and features.
