Samsung’s August Unpacked event is scheduled to take place today with foldable devices and wearables set to be unveiled, but it appears that OnePlus wants to steal its thunder.

The Chinese company recently shared a teaser on its social media handles, suggesting that it could soon unveil a dual-screen phone. The tweet features a brief video clip with some kind of two-screened mobile device, although it’s unclear exactly what we should expect.

OnePlus will be holding an event for this mystery device today, August 11 at 10 am ET, which is the same time that Samsung Unpacked is set to kick off.

The tweet read, “8.11 10am ET.”
