It's time to tear down the Galaxy S9 and take a look inside of that crazy variable aperture

Adverbs of degree

My phone has been through a lot lately and it's not quite over yet.

You've already seen me open up glass backed phones a million times, so you know the drill.

And luckily replacement panels are pretty cheap if you accidentally break one.

Or if you manage to scuff up the paint on the underside of the glass, a dbrand skin

I'll link all the stuff down in the video description.

There are 15 screws holding down those black plastics and the wireless charging coil.

I'll pop off that coil, the center plastic, and the bottom loud speaker, and then I'll

There's some very strong adhesive holding this battery to the frame of the phone.

You can see how it bent my pry tool trying to get this thing out.

I'll soften up the adhesive a bit with my heat gun and give it another shot.

Prying out that 3000 milliamp battery... it's the same size as the previous Galaxy S8.

Samsung claims 95% battery capacity retention after 2 years.

Meanwhile Apple says plan for a 20% drop in capacity about every year if they don't manually

The screen ribbon unclips like a little Lego, and then I'll make my way up to the front

It's an 8 megapixel, HDR capable unit, and pretty much the exact same thing we saw in

We'll get to the new stuff here in a second, but first I'll unclip the volume buttons and

these little signal wires down at the bottom, along with the white and blue wire cables.

And then of course the SIM card tray comes out with it's 400 gigabyte capacity SD card

It also has the water resistant rubber ring around the opening.

The whole motherboard can fold up and out of the phone at this point, allowing us to

access the final Lego-style connector attached to the bottom of the motherboard for the charging

I'll set the motherboard off to the side so we can tear open that camera unit in a second.

The interior of this phone is solid metal.

Samsung must anodize the entire frame at the same time, because it's all painted the same

But you can see the metal shining through the scratch marks underneath.

There is a long copper heat pipe to help keep the processor cool.

And then another copper sticker over some of the front facing sensors.

And lastly, a water damage indicator right up here by the SIM card tray.

This is how Samsung knows if your phone has gotten wet or not.

Remember, the Galaxy S9 is ip68 water resistant.

Definitely not the same thing as water proof.

I would just plan on keeping your phone dry.

It's got a little circular coin vibration motor inside with it's little gold contact

I still need to make that vibrator explanation video since there are several types used in

Our little buddy jack is tied in with one screw and a Lego-style connector here at the

Then there are 4 more screws holding down the charging port into the phone frame.

There's a little bit of adhesive under there, but the whole thing pulls up and away pretty

It's got a little rubber ring around the USB-C port to help keep water out out and the microphone

Now if I was going to do a screen replacement, I would use a ton of heat and basically break

There are massive machines that can do this safely and salvage the display if it's not

already damaged, but without those machines, just plan on the screen breaking completely

during the removal process and then installing your new one.

Let's jump into one of the major improvements on this Galaxy S9: the camera.

I don't tear down cameras very often, but I'll make an exception for this one.

After popping it out from it's slot in the motherboard, we can see a couple things.

First, we still have that optical image stabilization, that IOS that helps keep video footage looking

Now I'm interested in this variable aperture, you know, the little gizmo that physically

changes how much light can hit the sensor at a given point.

Popping off the protective housing, we can see that this aperture variation happens on

the exterior of the lens since I can touch it with my tweezers.

And the control mechanism for that aperture happens over here on the left hand side of

the lens where I can manually open and close the little circle by sliding my tweezers up

Of course all of this happens electronically automatically inside the camera.

It would automatically switch from 1.5 to 2.4 depending on the lighting situation on

But it's cool to see the hardware side of things during a teardown.

Thumbs up to Samsung for doing something new.

This is the same hardware you would find in a professional DSLR camera.

Apple is usually about 2 years behind, so you'll see this in an iPhone around 2020.

I'll pop out the lenses from the housing to reveal the camera sensor underneath.

This multicolored 12 megapixel rectangle is what receives the light through the lens and

One last look at the switch on the side of the lenses for the aperture movement.

That switch, including the optical stabilization, are most likely accomplished through magnets

since you can see each side of the lens has a little magnet attached that attracts this

And each magnet lines up with the copper coils inside of the housing.

They help keep things balanced and stabilized.

The camera won't ever be the same since there are some tiny little stabilizing rubber balls

inside that escaped when I took it apart.
