Folding phones have been around for several years now, but they haven’t quite achieved mainstream popularity. The market was also largely dominated by one brand (Samsung), at least in the U.S., but that’s changed in recent months and years. In 2023, OnePlus entered the foldable scene with the OnePlus Open.
While OnePlus is a smaller brand when you compare it to the likes of Apple, Samsung, and even Google, it still makes some very capable devices. The OnePlus 12 is one of the best Android phones you can buy today, and the OnePlus Pad remains a strong tablet recommendation.
So, how does the OnePlus Open hold up as OnePlus’ first folding phone? For the most part, it’s pretty fantastic.
About our OnePlus Open review
Our OnePlus Open review was originally published on October 19, 2023, after the phone’s launch. Christine Romero-Chan gave the OnePlus Open another look in April 2024 and added a new “six months later” section below.
Despite coming out in 2023, the OnePlus Open is still a fantastic foldable and holds up well even in 2024. It’s definitely still one of the best foldable phones you can buy right now.
As I picked up the OnePlus Open to revisit half a year later, I was reminded immediately why this was one of the best phones, especially for a foldable, that came out late last year. Even though it has a foldable form factor, the OnePlus Open is incredibly lightweight and comfortable to hold and use, even with one hand. It’s much lighter than the competition, which is the Samsung Galaxy Z Fold 5 and the Google Pixel Fold, thanks to the titanium alloy and the Flexion Hinge design. It’s light enough, and the cover display is a good, standard phone size so that it is comfortable to use single-handedly. I even found it nice to scroll through apps with one hand when I had it open and used the inner display too.
Speaking of displays, the OnePlus Open really has some of the best screens I’ve used. As I mentioned, the cover display is 6.31 inches, which is about the size of your average slab smartphone. This means it doesn’t feel too different to use, especially one-handed — one of the things that annoys me with the Galaxy Z Fold series is that the cover screen is so tall and narrow, making the on-screen keyboard more cramped than normal and resulting in a lot of typing errors from me when using it.
