It appears that Asus is testing a dual-slider phone, according to renders contained in tweets disseminated today by tipster Evan Blass. One of the unnamed handsets supports 5G and features a large edge-to-edge screen in front. On back, there is a dual-camera setup. The top slider houses a pair of selfie snappers including a 120-degree wide-angle lens. The bottom slider carries a Harman Kardon speaker, and the handset could feature an in-display fingerprint scanner. According to Blass, the person who designed this render was a member of the team that created the Asus ZenFone 5.
Other renders tweeted by Blass today show a different Asus phone with a similar dual-slider form factor. While the top slider on this other model also hosts a pair of selfie cameras, the bottom slider would be used to show contextual virtual controls and buttons. With the top slider open exposing the front-facing cameras, we would see virtual controls appear similar to what is shown in the render, including a shutter button. Other times, different buttons and sliders would be available depending on what the phone was being used for. This model features a rear-facing fingerprint scanner.
We have seen a number of different ideas peddled lately by phone manufacturers looking to improve the screen-to-body-ratio of their handsets without having to resort to a notch. ZTE recently showed off a couple of concept phones with edge-to-edge displays. One render depicts the Axon V with a dedicated panel jutting out from the side, containing a pair of selfie snappers and other front-facing sensors. The Axon S render shows a phone with a side-sliding panel that has cameras on both sides that would be used for both regular photos and selfies. As a result, the back panel is completely clean, an usual but interesting look.
