The OnePlus Open is a foldable phone with a 7.82 inch AMOLED primary display that folds in half to reveal a 6.31 inch cover screen that you can use when you don’t want to use your phone as a small tablet.

It’s the first foldable from OnePlus, a company that got its start by offering flagship-class specs at lower-than-Flagship prices. But that hasn’t really been true of OnePlus for a while, so it’s not surprising that like most foldables, the OnePlus Open is expensive. But at $1700, it’s a little cheaper than the competition: the Samsung Galaxy Z5 Fold and Google Pixel Fold both start at $1800.

The OnePlus Open is also surprisingly thin and light for a foldable, weighing as little as 239 grams and measuring under 6mm thick when open and under 12mm when folded closed.

By comparison, some phones without foldable displays come close to that. The Samsung Galaxy S23 Ultra, for example, is 8.9mm thick and weighs 234 grams.

The primary display on the OnePlus Open is a 2440 x 2268 pixel AMOLED LTPOP screen with 1 to 120 Hz refresh rates, typical brightness up to 1400 nits and peak brightness up to 2800 nits, 240 Hz touch response.

Meanwhile the cover display has similar characteristics, but it’s obviously much narrower. While the interior screen has a 1.08:1 aspect ratio, the outer display is a 2484 x 1116 pixel screen with a 20:9 aspect ratio. It also supports refresh rates up to 120 Hz, but on the low end it only goes down to 10 Hz.

The phone is powered by a Qualcomm Snapdragon 8 Gen 2 processor and, unlike most competing foldables, it only comes in a single memory and storage configuration at launch: 16GB of LPDDR5x memory and 512GB of UFS 4.0 storage.

Other features include a dual-cell battery with a combined capacity of 4,805 mAh, support for 67W fast charging, and a camera system that includes:

  • 48MP primary camera (Sony LYT-T808)
  • 64MP telephoto camera (Omnivision OV64B with 3X optical zoom)
  • 48MP ultra-wide camera (Sony IMX581 with 114 degree field of view and 3.5cm Macro support)

There are also two “front” cameras, including a 20MP camera on main display and a 32MP camera on the cover screen.

The OnePlus Open has a USB 3.1 Type-C port, a side-mounted fingerprint sensor, triple speakers with support for spatial audio and Dolby Atmos Sound, and there’s also support for Dolby Vision video playback.

Wireless capabilities include support for WiFi 7, Bluetooth 5.3, NFC, and 5G networks, and the phone supports dual SIM cards.

OnePlus ships the phone with OxygenOS 13.2 “Open Canvas” software, which is based on Android 13 but includes the company’s own optimizations for foldables that allows you to view up to four apps at a time on the primary display, resize or stretch apps across the screen. There’s also support for saving up to nine multi-app presets so you can launch a set of apps quickly.

The OnePlus Open comes in two color options: “Emerald Dusk” and “Voyager Black,” and the black one is a little thicker and heavier for some reason:

  • Emerald Dusk: 153.4 x 143.1 x 5.8mm (11.7mm closed) and 239 grams
  • Voyager Black: 153.4 x 143.1 x 5.9mm (11.9mm closed) and 245 grams

The phone is up for pre-order from OnePlus for $1700, but OnePlus is promising at least $200 off when you trade in any phone in any condition, effectively bringing the launch price down to $1500 if you’ve got an old junker lying around. Customers with more in-demand phones can also score up to $1,000 in credit.

Other launch promotion perks include a free pair of OnePlus Buds Pro 2 earbuds, a 3-month YouTube Premium subscription for free and 6 months of Google One 100GB cloud storage for free.

  1. How consistent are they on software support and security updates? So far all the reviews are positive and the price is good.

    1. The best foldable form-factor in my opinion, is to do this:
      – measure the maximum size allowable, or comfortable, to put into a pocket. Start from here. For example it is 180 x 90 x 18mm dimension.
      – next is to utilise that for the folded section. Meaning your unfolded section is twice as large but half as thick. Eg 180 x 180 x 9mm tablet dimensions.
      – maximise the screen size, and use clever ergonomics to not need much bezels. Examples; the front-screen is roughly 18:9 aspect ratio, roughly 7.40 inches diagonally, or abouts 170 x 80mm sized. While the back-screen is roughly 21:9 aspect ratio, roughly 7.00 inches diagonally, or abouts 170 x 60mm sized. The rear Camera Island is poking out towards the back-screen, to make space and utilise the best camera for Selfies.
      – Have it fold outwards. So the screen can be used anytime without having to fold, and the curve is at an obtuse angle to prevent a sharp crease.
      – think of the form-factor, and best ways to problem-solve. Example/ instead of a single boom-speaker and an earpiece, have four smaller speakers on each corner to allow stereo separation regardless of which mode or orientation you hold it at.
      – construct it meaningfully and for-purpose. Things must be balanced.
      ie/ Remove microSD slot but have it with massive (1TB) storage only. Remove Headphone Jack but increase battery capacity and include Wireless Earsets. Remove FM Radio and IrDa Blaster but include all the latest protocols. Don’t include a silo, but support Active Stylus or include one in the box. Restrict user access to the battery, but make it IP68 water resistant. Limit the software enhancements, but support long-term updates. Uninclude Reverse Wireless Charging but allow Wired Fast Charging. Lock the bootloader, but provide documentation, source, drivers, community support and a tool for enthusiasts and developers unlocking.

      All foldables, and many devices just don’t make the cut when thinking critically like this. The Sony device are pretty up there. The ASUS ZenFone Flip also another one to mention. The original Huawei Mate X Fold was one of the better concepts.

  2. I loved my OnePlus until it died a premature death due to super brief exposure to water. Never again will I buy a phone with no ingress protection.
