A collection of images of the Asus Zenfone 6 have appeared online but we are none the wiser as to what the final product will look like.

That's because the pictures show prototype models of the next flagship phone from Asus and each device seems to have a different front-facing camera.

One has a notch on the right-hand side of the top of the screen - a very odd place for it considering current trends.

While the notch itself is of the waterdrop style and therefore relatively small, its off-centre position is off-putting, we feel.

Another of the Asus Zenfone 6 prototypes shows a standard waterdrop style notch, in the top-centre of the screen. While the last is our preferred option as it has no notch at all.

Other details on the handset are currently unknown - only the images were posted on SlashLeaks.

Incidentally, this Zenfone 6 shouldn't be confused with the one released in 2014. That was a budget handset so called because it featured a 6-inch HD display and was part of a line-up that included 4 and 5-inch devices too..

The new phone might even come out with a different name, therefore.

We'll bring you more information when we have it.
