Taiwanese consumer electronics major Asus has released the first video trailer, revealing the key design features of the new Zenfone 3 series.

In the 34-seconds Asus Zenfone 3 teaser clip, the company shows the device will feature all-metal body with a completely new design language. The first change we see is the return of the power button to the right side of the metal-clad edge. Below it, there seems to be a SIM-slot.

Durng the fag end of the video teaser, the company shows rear-side of the three phones, each in different sizes – one a compact, a normal (around 5.0-inch) and another, a very big one probably a 6.0-inch model, rumoured to be he top-end Deluxe model.

It is interesting to note the only two phones seem to house square-shaped fingerprint reader below the camera module with LED flash on the left side and laser auto focus on the right, while the big model does not feature any bio-metric sensor. We believe the company might have incorporated it on the home button like some rival phones in the market.

The company has confirmed that the Zenvolution event will be streamed online on May 30 from Computex 2016, Taipei. With this, it has confirmed that Asus Zenfone 3 series will be officially unveiled this month end, as previously rumoured.

Since the launch is more than a week away, the company is expected to tease few more features.
