Dual Screen Smartphone? – Front AND Rear Displays Tested!

So here's a new one for you, a smartphone
with two screens. This is the Nubia X โ€“ an Android smartphone
that comes with two built in screens, one on the front, and one on the back. You know we couldn't let this one slip by
without a full on durability test. Let's get started. [Intro] So supposedly if you want to work this contraption,
there are two fingerprint readers on the sides that when gripped allow whatever's displayed
on the front screen to slip over onto the back panel while retaining full functionality. You can run the whole phone from back here. When the rear screen is turned off, it looks
just like a normal phone.

Let's see what happens when we scratch test
both screens. This Nubia X comes with a builtin screen protector
which is nice. I'll pull that off. The interesting thing with this phone is that
there's no notch, there's no front facing cameras or sensors that need to be hidden,
which allows the whole front of the phone to light up edge to edge, as a display with
pretty much no bezels. As we see from the scratch test, the front
is made with tempered glass, scratching at a level 6, with deeper grooves at a level
7. We've got to be fair to both screens though. I'll grip the sides and flip it around. The rear screen has a much lower refresh rate
than the front screen, and has kind of a yellow tinge to it. It's also covered with a screen protector. I've found that the yellowness is just a blue
light filter that can be removed. I'll show you that in a second. The blue backing on the phone is kind of like
reflective film that acts as a 2-way mirror, that hides the second screen when it's turned

And once again we get scratches at a level
6, with deeper grooves at a level 7. The rear screen is covered with the same glass. Part of what makes the front screen so bezel-less
is how small this earpiece is. I almost missed it. It's barely the thickness of my razor blade. The sides of the phone sound and look like
anodized aluminum. You can see the silver color shining through
under the blue coating, even here on the blue power button. One possible weak point in the frame is this
flattened portion where the fingerprint scanner resides.

It looks suspiciously like the design flaw
we saw on the iPad Pro, and we know how that one turned out. This phone has 2 of them, one on either side. I'm kind of nervous. The top of the phone has more metal and what
looks like an IR blaster up top for changing the channels on your TV. On the other side we have the SIM card tray,
volume rocker, and another flattened fingerprint reader…because why have just one fingerprint
reader when you can have two? Two is kind of the theme of this phone.

There are 2 SIM card slots as well, which
pair nicely with the two screens. Just one USB-C port down here at the bottom
alongside the loudspeaker holes. You might be thinking to yourself, 'Jerry,
why in the world would anyone want two screens on their phone?' Well let me tell you. There are no front facing cameras on the Nubia
X, just these two dual rear cameras: a 16 megapixel and 24 megapixel. One regular and the other one for that portrait
mode stuff. So when you want to take a selfie, you get
to use the powerful rear facing cameras while seeing your face at the same time. It's an interesting solution to the notch
problem, but also a solution that actually works. I'm impressed with the ingenuity โ€“ I genuinely
did not see this one coming. Like dual everything else on the phone, there
are two fingerprint scanners. You can use one or set up both for added security. And even with the damage inflicted on the
right side, the phone can still sense and unlock my fingerprint. Not too shabby, but at least there's a backup
if one ever fails. Now here's where things get interesting.

This front screen is a 6.2 inch 1080p IPS
LCD, meaning that after about 10 seconds we see the pixels getting hot, turning off and
going black, until the heat is removed, and then they slowly recover. They do recover completely though. Checking the back screen though, is where
we see one of the brilliant parts of the Nubia X design. An LCD screen when turned on has light shining
through every single pixel, even the black ones. So the whole display lights up. An LED screen or an AMOLED screen does not
have light shining through the black pixels, so you really can't tell when the screen is
on or off because the blacks are so black and emit no light. The Nubia X is using a 5.1 720p AMOLED screen
on the back, an LCD on the front, and AMOLED for the rear. You can see the pixels going white and not
recovering. Both technologies on one single device โ€“ burn
test justification. Checkmate on the haters.

The rear screen can act like an always-on
display without showing the actual edges of the screen. This provides the aesthetic illusion that
there's no screen at all on the back panel. Whether the screen is lit up or not, you can't
really see the rectangular edges due to the super black AMOLED pixels. It's interesting how all these innovative
smartphones keep popping up out of nowhere. No complaints from me. Here's a quick look at the rear display with
the blue light filter turned off. It looks completely normal and has as good
of quality as the front screen. I'm not sure why the Nubia X had that setting
turned on right out of the box. I think it looks pretty good. All of these awesome gimmicks though mean
nothing if the phone can't survive in your pocket for a few years. Here on my channel we put phones through years
of abuse in just a few minutes. It's time for the bend test. The dual fingerprint design on both side rails
might just be fatal.

With a solid flex from the front, we get minimal
bend, but no catastrophic damage, creeks or snaps. The rear screen looks fine. Even when bent from the front, the phone remains
intact and fully functional. No complaints here. The Nubia X is a structurally solid device,
even with all that fragile tech packed in, and while having screens on both sides, this
phone survives. As a side note, if one screen does actually
break, you can always just use the other as a back up since it does come with two. Do you think this phone is the future? Is a dual screen phone a better solution than
a motorized front facing camera? Which one do you prefer? Back to back screens are definitely fascinating. Hit that subscribe button if you haven't already. And come hang out with me on Instagram and

Thanks a ton for watching. I'll see you around..
