How do they do it? Well, we're already familiar with life without a headphone jack or home button. The solution to powering your phone without a cable should also be familiar: Wireless charging. 

The volume buttons are replaced by virtual buttons, combining pressure and capacitive sensors to give haptic feedback when you're pressing in the right spot (the Vivo Apex 2019 has icons to show you where the virtual buttons are).

And how do the phones produce sound without a speaker grille? They emit sound through the display itself, something also seen on high-end Sony TVs.

But it's the lack of a SIM card slot that shows how far from reality these prototypes are.

The other funny thing is that Meizu's "hole-less" does actually appear to have, uh, holes. If you look at the picture above, you'll see a number of small holes along the bottom, top and sides of the phone.

We don't know what they're for, but reports online say they're for the microphone -- which does make sense, as "little hole on the bottom and back" are exactly what microphones look like on smartphones.

Even one of the more practical features is getting called out for its impracticality. Wireless charging is cool -- my boss swears by it -- but netizens point out being forced to only charge wirelessly is impractical.

To be fair, there are wireless power banks... but they're much rarer than regular power banks, and you'd have to strap your phone to it.

Vivo's charging solution is more sensible than Meizu's, because their little wireless charging wire (yes, I know) attaches magnetically to the back of the phone, so you can theoretically stick it in your bag and not worry about it not aligning.

You'd think the upside to all this would be that the phones would be fully waterproof, but... phones with pretty serious water resistance exist today. And they have holes.

So with all the downsides, I guess this Weibo user's take is basically all of us: “I really don’t understand why it has to be ‘holeless’...”
