A lot of companies are working towards creating foldable devices and it seems like OnePlus might be the latest one to join the bandwagon. The company has recently teased its foldable phone on Twitter. The caption of the tweet suggests that there might be an official announcement about the device on August 11 at 10 am ET.
One thing to note is that the tweet was posted by OnePlus USA (@OnePlus_USA) and not OnePlus' global account that goes by the handle @OnePlus on Twitter. The tweet also comes ahead of Samsung's event where Samsung is expected to launch its Galaxy Fold and Flip series.
Looking at the short video teaser, it can be observed that the phone seems to have two individual displays attached together, like a Microsoft Surface Duo, as opposed to the flexible displays Samsung uses on its Fold devices. We can also see the familiar slider on the right side along with the power button and the volume rockers on the left side.
There also have been no previous leaks or news that hinted towards OnePlus working on its own Foldable devices. The announcement might be a concept release, or perhaps a roadmap of OnePlus' development towards future folding phones.

It looks like it was a really terrible publicity stunt by the PR team of @OnePlus_USA. As promised, the company did update us about their plans at 10 am EST but it was about a 50 percent discount on its latest device - the OnePlus 9.
As you can see in the above video tweeted by OnePlus USA, the "folding phone" turns out to be two OnePlus 9 devices stacked up side-to-side. The 50 percent discount is still good if you have been planning to get a flagship OnePlus device. Although aimed to catch the thunder of Samsung's Unpacked event (which is happening right now), it would have been better if OnePlus communicated the offer in a better way.
