The Samsung Galaxy Z Fold 3 is now the heavyweight foldable phone to beat, and when the Z Fold 4 replaces it, it’ll likely grab first place on our list of the best foldable phones – but Vivo is likely to be the next manufacturer to try to wiggle its way in.

The Vivo X Fold will announce on April 11, and we know this because the company has been heavily teasing the phone – in fact, it’s posted two videos of the upcoming foldable on Chinese social media network Weibo.

The first video, which was posted earliest, shows the phone’s outer display, and ends with the thing starting to open. As well as a volume rocker and power button, we can see something that looks like an alert slider, so it’s possible the phone will get one of them.

Moreover, the second video is the most revealing, showing the phone from loads of angles – well, except for the one angle that would show if there’s definitely a volume rocker or not.

We can see very clearly that this is an outwards-folding book-style foldable, like Samsung’s Z Folds, with a very large inner screen and a circular camera bump housing four lenses.

Something else is obvious as well: this is a very good-looking foldable phone.
