An unusual image has revealed a world-beating OnePlus Open 2 spec

Hints don’t get much bigger than the one dropped by Oppo Chief Product Officer Pete Lau on the Chinese social network Weibo about the Oppo Find N5. What makes this hint extra special is that the Oppo Find N5 is a big-screen folding phone that’s almost certainly going to very closely resemble the OnePlus Open 2. As tech fans may already know, while Lau works for Oppo now, he co-founded OnePlus.

“The world’s thinnest folding flagship, Oppo Find N5, see you in February,” reads the message posted to Weibo, which is accompanied by a teaser image showing a pencil obscuring the side of a phone behind it. The message was also sent from a Find N5, showing Lau is very familiar with the new foldable already.

What does the image tell us? There isn’t a universal standard size for a pencil, but on average, the diameter seems to measure around 7mm to 10mm, and the edge of the phone behind the pencil in Lau’s teaser image appears to be around half the pencil’s diameter. The phone is open rather than folded, and if it’s to beat the current “world’s thinnest foldable,” the Honor Magic V3, the Oppo Find N5 needs to be less than 4.4mm thick unfolded and less than 9.3mm folded.

Lau’s teaser and confirmation of the Find N5’s record-beating dimensions backs up a recent rumor claiming the OnePlus Open 2 would be the thinnest folding phone we’ve seen yet, as well as another earlier rumor stating that when folded up, the OnePlus Open 2 would measure less than 10mm. It seems both of these are on track to be accurate.

Oppo’s foldable release schedule has been difficult to predict, and Lau’s message shows it has skipped the Find N4 series and headed straight to the N5. OnePlus announced the OnePlus Open at the end of 2023 and followed it up with the slightly refreshed OnePlus Open Apex Edition in 2024. It means a sequel to both it and the Oppo Find N3 are overdue, and the OnePlus Open 2’s release may quickly follow the Find N5’s announcement in China.

Oppo’s Chief Product Officer, Pete Lau, recently teased the upcoming Oppo Find N5, describing it as the “world’s thinnest folding flagship" while also offering a photo of the device hidden behind a pencil, just to demonstrate its lack of girth. Just a few days later, Finnish leaker Teme shared photos that may show the new device in more detail, and emphasize just how thin it will be.

As shown in the three images below, the Oppo Find N5 appears to have what it takes to become the thinnest folding flagship phone on the market. One of the photos also shows the phone’s camera layout. As the leaker explains: “Oppo Find N5 thinness and camera layout. OnePlus has not confirmed anything yet whether this will also be the [OnePlus] Open 2.”

Forget the Galaxy S25 Slim. The OnePlus Open 2 could be the thinnest foldable ever
A side view of the OnePlus Open.

With the launch of the Galaxy S25 series just around the corner, there has been a lot of speculation about the so-called S25 Slim. It might be too early to sing its praises, though; according to a reliable tipster, the upcoming OnePlus Open 2 (also known as the Oppo Find N5 in the Chinese market) might be the thinnest foldable phone ever made.

Digital Chat Station, a leaker with a pretty trustworthy track record, has claimed the OnePlus Open 2 will beat out even the Honor Magic V3. The Honor Magic V3 is only 9.2mm folded and 4.35mm unfolded — the slimmest on the market — so if the OnePlus Open 2 manages to squeeze its hardware into an even smaller form factor, it's going to set records. In addition, Digital Chat Station also claims the chassis will be made of titanium.

It’s 2025 and the OnePlus Pad 2 is still my favorite Android tablet

For decades, smartphones have progressively grown larger, and subsequently, so have tablets, and the lines between big phones and small tablets have grown progressively more blurry. Some companies make smaller phones or tablets, but these are exceptions to the rule.

A case in point is Samsung’s tablet portfolio. Samsung debuted the Galaxy Tab S10 series in October but dropped a replacement for the regular Galaxy Tab S9. The Galaxy Tab S10 Plus and Galaxy Tab S10 Ultra pick up where their predecessors left off, but if you’re a Galaxy Tab S9 user, you’ll either have to buy the FE series or switch to an alternative.
