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 – 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
off.

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 – 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 – 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..

Nubia Red Magic 5G – Unboxing, Setup, and Review – (4K 60P)

hi everyone Aaron here for ZolloTech and
this is the Nubia red magic 5g this is their latest gaming phone with 5g
technology built in and comes in between five and six hundred dollars or so and
is available with eight gigabytes or up to sixteen gigabytes of RAM with 128 or
256 gigabytes of storage now let's flip this over and unbox it here so we'll
take the packaging off here or the wrapper and let's go ahead and open it
up and inside we have the phone itself now it should have an under the screen
fingerprint sensor we'll take a closer look at that in a moment and let's take
this packaging off and we have three different envelopes or three different
packages so inside this one we've got a SIM card removal tool then we've got our
Quick Start Guide it says here just some information about the phone and then a
warranty card as well now on the right we have a charging brick and this is not
the United States variant but there will be a United States variants USB a 2 USB
see look this back and then in here we should have our USB C charge cable so
and here is the charging cable it's a nice red color again USB a 2 USB C so
let's set that aside and take a closer look at the phone itself let's go ahead
and take the wrapper off the phone this is a really interesting color you can
see it says 5g here you've got your cameras so let's go over the specs of
the phone we'll take a look at the design the specs and everything else now
around the outside edge we have a little switch here this is usually a gaming
switch we have a little vent on the side so it's got air that goes through one
side and out the other to keep the processor cool
then we've got some pogo pins for some other accessories they sell on top we
have a microphone and a 3.5 millimeter headphone jack on the right again we've
got these shoulder buttons just like last year's Nubia
magic 3s you've got shoulder buttons here you've got your vent or intake and
then you've got a power and volume button here and they feel like they're
metal but I'm not sure if they are on the bottom we've got a speaker and then
we've also got our USB C charging port along with a microphone now we also have
a SIM card slot as well now we'll pop out the SIM card tray and
we should have dual SIM capability so on each side we can place a SIM card
there is no expandable storage in this phone now let's take a look at the specs
now this is the 12 gigabyte model with 256 gigabytes of storage internally we
have a qualcomm snapdragon 865 along with superfast ufs 3.0 storage and ddr5
ram so not only is the display 144 Hertz it's six point six five inches it's an
AMOLED display 1080 by 2340 with 388 pixels per inch and it supports DCI p3
now not only is it a hundred and forty-four Hertz but it has a 240 hertz
touch esports ultra smooth display it also has 300 Hertz touch sensing
capability on the triggers now on the back we have a couple different cameras
we have a 64 megapixel Sony sensor with an F 1.8 wide lens we also have an 8
megapixel ultra wide and a 2 megapixel macro camera so that's pretty
interesting we can also record in 4k 60 or 8k as well on the front we have an 8
megapixel F 2.0 wide forward facing camera as well internally we have a 4500
milliamp hour battery that supports fast charging with 55 watt chargers and
should charge at about 56% in 15 minutes it will charge 100% in 40 minutes if you
have that fast charger now it also supports Wi-Fi 802 dot 11a b/g/n AC and
a X or Wi-Fi 6 and bluetooth 5.0 a2dp apdex le so this is packed full of specs
for half the price of what you get with a samsung s 20 ultra for example but we
don't have that huge camera array on the back so let's go ahead and boot it up there we go now we'll go ahead and set
it up so we'll connect to a mobile network now it's connecting and checking
for updates and one thing I noticed is it says 90
Hertz in the upper left of the display so it says detected a new version update
now so we'll go ahead and update and it says it optimizes Play Store
compatibility and camera applications so let's go ahead and update this now it's
asking if I want to copy apps and data I won't copy I'll set it up as new and
it says just a sec checking info and we can sign in with Google or do that later
we'll skip that for now and just try to get to the home screen as fast as we can
here now this does have an under the screen fingerprint sensor so it says
unlock with fingerprint we'll hit next so we'll go ahead and setup the
fingerprint sensor every time we do it you can see the screen gets brighter
that's kind of interesting so it's must be optical similar to what oneplus has
says fingerprint add it will hit next and it says adding finishing touches
just to give you a size idea here is the red magic 5g next to a pixel for Excel
so you'll see the size difference thickness wise it's actually not too big
it has a nice curved edge to it so it's not too much bigger but the display is
bigger now if we put our finger on the fingerprint sensor there's an
interesting animation and we won't copy here now this is the home screen of the
nubia red magic 5g and we'll go to settings here after it updated and you
can see this is the 12 gigabyte variant with 256 gigabytes of storage running
Android 10 with the March 1st 2020 security patch so it's actually pretty
up-to-date already maybe there'll be a new update very soon with the latest
security patch now it's also running at red magic OS at version 3.0 now the home
screen skin looks like this it's pretty familiar as far as any other you've seen
in rent magic now a couple of things to know this is very similar to the Google
now launcher so if I slide over here we've got basically our Google now view
but you can't swipe up to go back you have to swipe back to get there so it's
kind of interesting and then it's highly customizable so you can see I have it
set to 144 Hertz for the display and you have that option to change it from 144
Hertz to 90 or 60 and leave it in the status bar so you can change it to 144
for eSports change it back when you need to save some
so that's really nice as well now in the notification in status bar we can also
show our network speed so right now it's gonna give us our overall speed if we're
using network connectivity and it's just nice that we have all these little
customizable options that are really key to people that are playing games on
their phone and if you don't like the gestures that I've been using you can
get back the navigation bar switch it out to whatever you'd like and other
than that you can see we have neo AI for smart game neo speed that helps you with
gaming and you've just got all these really nice effects such as colorful
lighting effects or low power off and all sorts of things now another
interesting thing is other than the lighting we have the cooling fan and we
can tell it to turn on to max speed or even have it turned on for quick
charging so it keeps the battery cool and then you can have it shut down as
well so it's really neat to have all of these different options and it's just
something that's a little bit different than anything else you see out there and
you also have some options such as always-on display they have some nice
options here but the thing that sets this phone apart from others that I've
seen is not its skin but rather it's a gaming mode so in the upper left we have
this little switch here we flip the switch and we go into our game mode and
so you can see we have access to the cooling fan RGB LED strips so if we go
into that we have an RGB LED strip on the back so we'll wait for it to turn on
or off it it lights up this part right here
I can turn it on or off if you want to use that and then also the cooling fan
on or off and now we also have some other options if we swipe from the right
we have options for our fan we have our display switch being switched to 144
Hertz just by tapping on it we also have 4d shocks so it's supposed to be a
better haptic feedback motor and then access to things such as blocking calls
blocking messages or taking a snap of the phone basically a screen shot and
then it also tells us what our CPU and GPU are running at and it's got a bunch
of really interesting stats that you don't normally see on other phones so
it's definitely set up for gaming now let me go ahead and add some games so we
can take a closer look now I've added a couple different games to this phone and
let's go into the gaming mode now as soon as I do this you're going to hear
the fans kick so we'll rotate it here and it's not
terribly loud let's see if you can hear this now that's what the fans ounds like
you can turn it off with this button here and then it kicks back on and it
seems to do a good job you can actually feel air blowing out of the bottom here
so let's go ahead and try a game now because this is in the game mode here
you can go through swipe through your games add a game you can sign in and
then if you swipe to the right it also again shows you what your CPU usage is
at you can assign your triggers and things like that it's really nice so
let's go into asphalt 9 first it seems super fast as well and the sound is
quite good but I have it turned down for this video now this game is super smooth
at 144 Hertz you can see that everything is running nice and smooth it's in full
resolution everything's turned all the way up and the phone is staying fairly
cool but it is getting a little bit warm and let me go ahead and go back to the
game space here you can just swipe in at any time and the back of the phone is
warming up a little bit but that's to be expected when playing something
intensive and ramping up the CPU and GPU let's swipe over and go to call of duty
and check that out so this game is super smooth on this display it looks great it
looks better than I remember it on the Xbox 360 and in general it's very
playable no problems here the framerate super smooth you've got that fan keeping
everything nice and cool now if we want to exit the game we can just swipe to
the right go to the game space and we're back to the main screen flip our switch
here and we're back to the home screen the fan shuts off and you just use the
phone as a normal device and all of your settings go back to normal it's a really
nice way to do a gaming phone and it's pretty interesting now as far as the
camera is concerned on the back we have some interesting options so if we go
into the camera you'll see that we have some zoom options so let me put the
pixel 4xl underneath so you can see this but we can go to 3 X 5 X and then 10 X
and it's actually pretty clear it's not too bad and we also have the option for
macro photos which you don't really see too often so what you need to do in
order to get macro is you actually go into the camera
family here and then in the camera family you go to macro and so maybe I
want to get really close to this looks like it's in focus there we go we've got
some focus peaking which means just the red outline here that lets you know
you're in focus and you can see we have a macro shot so if we zoom in it's
actually pretty nice so it's nice to have that as an option on the camera and
then also you have some really nice video options as well
so if we go into the options here you see we've got grid and things like that
let's see if we can go back let's go back to photo or video here rather then
go back into options and you'll see for the resolutions we have all the way up
to 8k but it recommends it for outdoor use because it probably needs a lot of
light so I've set it to 4k 60 so that's really nice it's got that option so
let's go ahead and see what it sounds like we'll go ahead and hit record and
now we're recording from the red magic 5g so this is what it sounds like just
recording out of it it does seem to have some odd focus issues from time to time
it doesn't seem like it's dual pixel autofocus but this phone is fine for
most people as far as photos and video but it's not going to be something like
an S 20 or a pixel for excel for photos at least with this current version of
software so here's my video on the Nubia red magic 3s let's go ahead and take a
listen to the speaker's quick and turn them up they go nice and loud but they
do distort it high-end so it's pretty good you've got a nice stereo sound as
well that's it for the Nubia red magic 5g let me know what you think about this
color and the phone in general in the comments below for its price it's really
hard to be as far as what you get for specs gaming you've got a fan you don't
have an IP rating really that's going to protect it because you have open vents
and things but in general it's a solid package for the price and you've got a
hundred and forty-four Hertz display which is really impressive but again let
me know what you think in the comments below I'll link this wallpaper in the
description as I always do and if you haven't subscribed already please

Vivo Nex Dual Screen – Triple Camera – Durability Test!

Remember that phone from last year with the
motorized pop-up camera – the Vivo Nex S? Well Vivo is back at it again with another
super innovative design, with both a screen on the front and back of their latest flagship. In the box comes with headphones, charger,
and a thick bumper case to protect the phone from drops. It's time to see how much thought Vivo put
into durability. Let's get started. [Intro] This is the second dual screen phone we've
seen. With the Nubia X, switching screens was a
carefully calculated, simultaneous double button press. But with this Vivo phone, pressing one power
button on the right side of the phone will activate whatever side is facing you much
easier. It also has a 3 finger side swipe to switch
between the screens on the go, which is as equally easy. So the whole point of a dual screen phone
is to one, look cool, but also to get rid of an notches or hole punches in the larger
front display. With an additional screen on the back, all
selfies can be done with the higher quality rear main cameras, instead of having lower
quality front cameras taking up space inside of a notch.

The main camera on this phone has 3 LED lights
for better lit pictures. Two of which can activate a circular lunar
ring for more even light during pictures or videos. You know, the same circular lights that YouTubers
might use during makeup tutorials. I'm going to leave the makeup tutorials to
the experts, but a ring light is definitely a cool addition to a cell phone camera. The included case has a solid fit. I always have a case on my personal device,
so I'm glad Vivo added some extra protection in the box. Speaking of protection, there is also an included
plastic screen protector on the front surface. The guys over at Vivo are getting all the
bonus points today. As you know, with my systematic durability
test, we check the scratch resistance of the screen with Mohs scale of hardness.

It's a pretty safe bet that if a company isn't
advertising sapphire, it's probably going to be tempered glass, which is where we start
seeing faint scratches at a level 6, with deeper grooves at a level 7. Vivo was the first manufacturer to come out
with an under display fingerprint scanner, and the same technology is here in this phone
as well. Underneath the front screen, protected by
the front glass, the display shines up onto your fingerprint. And the little sensor underneath the display
can tell if it's your finger or not so you can unlock the phone securely.

With two screens, we need double the testing
since there's twice as much real estate to cover. Let's scratch test the back. Dbrand should start making clear skins for
these dual screen phones. This side as well is covered by a screen protector,
which makes sense. Screen protectors not only stop scratches,
but also add a cushion layer of impact protection so brittle glass doesn't shatter right away
during a drop. This time after testing all the different
levels, we still find tempered glass covering the back panel, resulting in scratches at
6, with deeper grooves at a level 7.

The rear design of the Vivo dual screen phone
is unique. Instead of a metal lip around the camera lens,
the whole circular unit is glass and protrudes just slightly over the top of the rear glass
panel. With it's own little screen protector, the
circular camera lens is very solidly adhered to the rear panel. Even with some prying from my razor blade,
it doesn't want to come off. The back panel, surprisingly, does have it's
own earpiece, a bi-directional earpiece speaker shooting out both the front and the back. This will be fun to see from the inside. It's a thin little sliver, especially here
on the front side, to minimize the bezels. But the grille can come off on it's own. There isn't much adhesive holding it in place.

It's definitely interesting to see speaker
grilles on both sides of the phone. Speaking of sides, the material inside of
this dual screen sandwich is metal, the long volume button, and power buttons are both
made from metal. The bottom of the phone has a loud speaker
and USB-C charging port, along with a dual SIM card tray, with a protective rubber ring
around the opening to help keep water out. The Vivo Nex Dual Display doesn't have an
official IP rating, but it's good to see some steps were taken. This hole is protected and I'll have to check
the other holes from the inside during the teardown.

The far side of the phone is also made from
metal, along with the second tower button with Vivo printed on the surface. And what's this? Dost mine eyes deceive me? A headphone jack. You gotta love a phone with all the features. Another interesting design choice is at the
edge of the screen on both the front and the back are surrounded by a layer of plastic. Plastic as we know is much softer than metal
or glass, so it does provide a nice cushion layer between the hard metal sides and the
clear brittle glass. So if it does happen to get dropped, it might
not break as easy.

It's a good thing, and not something you would
notice at first glance. With the previous dual screen phone I tested,
the Nubia X, it had an LCD front panel, while the smaller rear panel was AMOLED. This phone, the Vivo Nex Dual Display, has
a larger rear screen than the Nubia at 5.5 inches and it's still a 1080p AMOLED. It's kind of sad when you think that the backup
screen on this phone is still higher resolution than Apple's iPhone XR. No permanent marks were left on the display,
even after my lighter was in place for 45 seconds. It might be the dual thickness of the clear
camera lens glass. But even with all that heat, there is no separation
of the rather unique circular lens. There's a 12 megapixel main camera, a 2 megapixel
depth sensor, and another 3D camera called TOF for Time of Flight for facial recognition
are all back here.

The TOF camera has some pretty cool 3D scanning
capabilities. I jumped into the camera app to check it out. It has the standard measure of banana features
that a lot of phones have. But it also has this pretty in depth 3D face
scanning unlocking thing that Vivo claims is better than Apple's. But I think we can all agree that this is
either super creepy or super awesome. Isn't that right, Digital Jerry? [Jerry nods] The front screen is a massive 6.4 inch, no
notch, 1080p AMOLED display. This time with different placement of my lighter,
and without the dual layers of glass, a white burn mark appeared at about 27 seconds and
never did quite recover. And now for the bend test. This phone has no moving parts, just one solid
hunk of glass, metal and plastic. And the whole contraption seems very heavy
and very solid, with only a slight bend during the flex, but with no creaks, snaps, kinks,
or cracks anywhere in the body, even when bent from both directions. I like where things are headed. This whole flagship phone with dual screens,
3D camera, headphone jack, and in-screen fingerprint scanner is still cheaper than Apple's budget
iPhone, the XR.

And Vivo's phone comes with double the internal
memory. Vivo's got my attention. I'm impressed and I'm excited to see what
they come out with next. Hit that subscribe button if you haven't already
so we can find out together. And come hang out with me over on Twitter. Thanks a ton for watching. I'll see you around..
