This dual screen Nubia Z20 is low-key one of my favorite phones of the year. At $550,

it's half the cost of a normal flagship, yet has triple cameras and screens on both sides

that can mirror each other. Or act as dual monitors. And now it's time to see how it

all works from the inside. This video is sponsored by Skillshare.

When both screens are off, the Nubia Z20 looks pretty much just like any other smartphone,

so getting inside it should be interesting. There never are any instruction books for

tear downs like this, so we'll take an educated guess and start from the backside with the

smaller secondary screen. Heating everything up till it's barely too hot to touch and then

lifting up with my large suction cup while simultaneously slicing through the adhesive

under the glass and continuing this process all the way around the edge of the phone.

Finally, with all the adhesive cut, the back screen can fold open from the phone like a

book, revealing a long display ribbon that crosses the length of the phone and plugs

into the motherboard. It's probably a bad idea to turn the phone on at this point, but

we're going to go ahead and do it anyway. Normally you can swap between the screens

by physically flipping the phone around, but you can also manually trigger the screen swap

with an on-screen button. And since the screens are currently side-by-side, that's what we're

going to be using right now. I can have one app open on the front, and a different app

open on the back. It's a pretty ingenious little system that Nubia is implementing and

You can see the camera lens scoping out the underside of the rear panel. Having the patient

awake during surgery is kind of fun. Looks like you don't need the rear panel to take

selfies. Anyway, let's go back to the teardown. There is a long black underscreen shield between

the back of the AMOLED screen and the battery. But there is no way to unplug that battery

just yet. There is a small metal bracket over the rear display connector. I'll unscrew that

little screw holding it in place and then unsnap the screen connector from the phone

like a little Lego. This is the AMOLED screen. The only way to get a display this this is

by using an OLED panel where each individual pixel lights itself. An LCD screen which has

a back light would be a bit thicker than this and take up more space inside of the phone.

OLED is pretty cool technology. The same construction is also why OLED TVs are much thinner than

I can remove the 8 Phillips head screws holding down the top metal and plastic shield of the

phone. Pulling it away from the body, we see that it comes attached to the triple LED camera

flash. Two colors on the left and a single color on the right – both of which plug

into the motherboard with the same Lego-style connector. I'll unplug the battery first and

make my way around to the other ribbon connectors, unclipping the screen and bottom extension

ribbons, along with the smaller screen switching side button ribbons.

Down at the bottom of the phone we have another 8 screws holding down the lower plastics and

loudspeaker. Pulling it away reveals that the loudspeaker has no balls inside, but it

does have the gold contact pads that allow it to communicate with the charging port board.

There is no water resistance inside this phone. I'll unclip the charging port, unscrew one

more screw down here, and then I can pull the coin-style vibrator motor and USB-C charging

port out of the phone at the same time. The two are soldered together. The phone looks

new and modern on the outside, but they are using some older-style build methods on the

Removing the last few small ribbons from the top of the motherboard. I also go to remove

the black signal wire and it accidentally pops the head completely off of the motherboard.

That super cheap price point is starting to show itself a little inside of the phone with

that soldered vibrator motor and weak signal wire connections. I'll pull the SIM card tray

out. It's got room for two SIM cards but no memory card expansion slot, which for me is

pretty important, especially as the phone gets older.

There is one more screw at the top of the motherboard, and then I can lift the whole

motherboard away from the Nubia Z20 housing. It comes off with a triple camera setup still

attached and leaves behind a gigantic blob of pink Double Bubble-style thermal paste

underneath. The Z20 is using the metal frame of the phone as a heat dissipation system.

The triple camera setup is all mounted together in their own metal housing and each camera

has it's own Lego-style connector attached to the motherboard. The main 48 megapixel

camera is on the left, which does have the optical image stabilization. And then we have

the 16 megapixel ultra wide camera in the center and the 8 megapixel 3x telephoto zoom

lens on the right side. Neither of the 2 secondary cameras have OIS.

I'll plug the cameras back into the motherboard. I'm a huge fan of more phones coming out with

this triple camera setup. Now for the battery. It is a few pennies cheaper to make the battery

permanent and that's what Nubia has done with the Z20. This makes battery removal super

dangerous. Bent batteries can tear and explode and start on fire, which isn't my favorite

thing on the inside of a phone. Plus there are a few fragile ribbons underneath the battery

that should be more protected. Eventually the battery does come out, but now that it's

been bent, the internal layers have probably touched and it'll just slowly start expanding

over the next few months, causing the phone to die a slow and painful death. So the best

thing to do for the phone and the planet is just for Nubia to use removable adhesive next

time, even if it does cost a few pennies more.

The 4000 milliamp hour battery can fast charge at 27 watts. The 1080p larger front screen

is glued into the metal housing and is using that same super thin AMOLED technology to

utilize the least amount of space inside of the phone. It's pretty amazing how thing these

things can get. The display is just as thin as the piece of glass that's on the outside

protecting it. The smaller rear display is 720p.

I'll put the battery back in and start putting this little guy back together. The goal is

to have a working phone when I'm finished. I do feel like Nubia did cut some costs in

a few areas with that weaker antenna connector, permanent battery, and a soldered vibrator.

It's got the outside looking like a prime Olympic athlete, but the inside's looking

more like a fast food eating couch potato. It all comes together to make a decent phone

though, and still just proves that you don't need to spend $1000 for a flagship when a

$550 phone can still get the job done just fine, even if the insides aren't as fine-tuned

I'll get the rear screen plugged in with a metal bracket in place. And then the whole

thing folds shut into a functional device again. I'm a fan. It's still definitely one

of my favorite phones of the year. I like it when companies innovate and try new things.

The dual screen Nubia Z20 gets a thumbs up from me.
