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

  • camera unit.

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

  • Let's get started.

  • [Intro]

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

  • Heat is your best friend.

  • Glass is glass.

  • 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

  • is equally inexpensive.

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

  • Let's get to the good stuff.

  • 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

  • unplug the battery.

  • 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

  • throttle you first anyway.

  • You know what you sign up for.

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

  • facing camera.

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

  • last year's phone.

  • 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

  • slot.

  • 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

  • port.

  • 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

  • color inside and out.

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

  • It's a very very solidly built phone.

  • 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

  • pads.

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

  • cell phones these days.

  • So watch out for that one.

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

  • bottom of the phone.

  • I'll release those and pop him out.

  • 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

  • smoothly.

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

  • hole is down here on this board as well.

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

  • the screen off of the phone frame.

  • 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

  • super smooth, but that's pretty common.

  • 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

  • and down on the internal switch.

  • 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

  • hand.

  • 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.

  • We aren't done with the teardown though.

  • 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

  • turns it into an image for your phone.

  • 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

  • screw.

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

  • Pretty cool.

  • They help keep things balanced and stabilized.

  • I'll start reassembling the phone.

  • 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.

  • Luckily, replacement cameras are pretty inexpensive so I'll just buy another when replacements

  • become available.

  • The charging port is in place and screwed down.

  • And if we look up here on the left we see Bixby's little home.

  • It's got the one button and a little ribbon with some gold contact pads.

  • It looks pretty easy to remove if someone wants to be adventurous.

  • They can just pop the button out, or leave the button in place and just rip out the contact

  • pads so he never works again.

  • I'm not suggesting murder, I'm just saying it's possible.

  • The motherboard gets clipped in at the bottom first with the charging port and then set

  • down into the aluminum frame of the Galaxy S9.

  • If you noticed, I'm leaving the camera unattached right now, but the phone should still work

  • without it.

  • The front facing camera is plugged in and then the screen ribbon is clipped into the

  • motherboard like a little Lego, along with the 3 little signal wires at the bottom.

  • Now one more subtle difference between the S9 and the S8 that you probably won't hear

  • anywhere else is about the camera flash.

  • It's still a single colored LED flash, but the S9 has a diffuser in it while the S8 does

  • not.

  • Light diffusers are usually preferred among photographers since it's a little less harsh

  • on the image.

  • And the Galaxy S9 now has one in place.

  • Not a reason to go out and buy a whole new phone of course, but it is still something

  • new.

  • And I guess if I have to be nice, Apple has been diffusing their flashes on their iPhones

  • for quite a while now.

  • Anyway, the battery is back in place and plugged in, along with the headphone jack and this

  • little screw.

  • And this is the part where you would normally get the plastics back on and the 15 screws

  • screwed back into place, but since my phone has been torn down and clarified a bit, this

  • portion of the video is going to be a little different.

  • I'll get some double sided tape to hold that glass back panel in place.

  • And after clipping in the fingerprint scanner, I can see if the whole phone works or not.

  • It turns on even without the camera unit in place.

  • And the whole thing appears to be working.

  • It finds Wi-Fi, Bluetooth, and the front camera works.

  • But as soon as I flip it to the rear camera, the camera app dies with a “camera failed

  • warning...probably because it just doesn't exist anymore.

  • But yeah, if you're bored of a normal looking phone, make sure you check out the dbrand

  • link in the description.

  • Show them some love for supporting my channel, and build your own phone by clicking that

  • link.

  • I think this camo skin is pretty sweet.

  • Thanks for joining me on the teardown on this Galaxy S9, and if I've earned it, hit that

  • subscribe button.

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