    • Samsung's motto for this massive phone could well be "no spec left behind." Pick a spec, and Samsung has dialed it all the way up to eleve—er, twenty. Just look at these numbers:

    • 6.9" Quad HD+ Dynamic AMOLED Infinity-O Display (3200x1440, 511ppi), 60 or 120 Hz refresh rate

    • Snapdragon 865 processor paired with 12 GB of LPDDR5 RAM (16 GB optional)

    • 128 GB flash storage (512 GB optional) expandable via MicroSD

    • 5,000 mAh battery

    • Cameras, just a few: 12 MP ƒ/2.2 ultra-wide; 108 MP ƒ/1.8 wide-angle; 48 MP ƒ/3.5 telephoto. Plus a mere 40 MP ƒ/2.2 selfie camera

    • Now we know what happened to Galaxies S11 through S19: This phone ate them. It's a monster.

    • Samsung just brought the biggest contender to the Camera Bump Contest—the one you didn't know was happening—and now it's over! Everybody go home.

    • Technically you could make a bigger bump, but at some point it just becomes a thicker phone body with no bump at all. Crazy talk, we know.

    • Here's a nifty visual comparison with the iPhone 11 Pro Max with its raised triple bump, and the Note10+5G with its single Martinsville Speedway bump.

    • Our unit might be defective—we couldn't find anywhere to plug in our headphones. And the Bixby button is gone, so who are we supposed to loudly complain to?

    • While we warm up our tools, our pals at Creative Electron warm up the Ultra—with some X-rays.

    • We're seeing a lot of internal similarities to last year's Note10+5G, including those mmwave antennas embedded into the frame and an earpiece speaker that fires upward from behind the display.

    • Some differences are subtle, but here's one that's not: check out that enormous zoom camera near the power buttons. It takes up the space of two or three regular-sized camera modules. More on that in a bit!

    • Per our usual SOP (Samsung Opening Procedure), we start looking for a way in through the back, leading the way with some heat.

    • The adhesive here seems tougher than usual for Samsung, but we're not certain whether it's just normal variation or something more nefarious.

    • Luckily, we brought our ultra-sized suction cup for such occasions.

    • With all that adhesive, we're relieved that the back comes off without any cable-snapping booby traps.

    • Look at the cone-shaped extensions on those camera modules! No wonder that camera bump is so thick. Samsung is done with the Sony sensors that everyone else is using and has decided to make their own modules for the S20.

    • We continue to raid the toolbag for bigger and beefier tools—like this Manta kit driver, which works equally well for swatting away screws and smashing walnuts. Just don't mix them up.

    • These screws are all named Phillip. We like Phillip; it's a solid name for a screw.

    • With the top layer of antennas, speaker, and charge coils flipped aside, we get a clear look at the internals. It does look a lot like a Note10+ 5G in there, if you eliminated the stylus and used that space for more battery.

    • Stay tuned for our teardown wallpaper post! We'll have your Ultra wallpapers, as well as your Plus and your standard S20.

    • We waste no time extracting the main board, which comes so laden with cameras, millimeter-wave hardware, and extra board layers that it feels like only half a victory. Time to start chucking things over-board.

    • We can't resist cracking open the massive 108 MP wide-angle camera after we pull it free—Samsung hasn't been shy about this sensor's capabilities.

    • The sensor covers over double the surface area of the iPhone 11 Pro's 12 MP primary sensor, shown here for comparison.

    • Bigger sensors and more pixels don't always mean better images, though! 108 million pixels crammed into a 9.5 mm x 7.3 mm rectangle makes for some very tiny pixels, and that tends to produce noisy images in low-light conditions.

    • Samsung claims that this new sensor is able to shoot clear photos even in low light conditions thanks to a new barrier built around each pixel, plus a 3x3 pixel binning method they're calling "nona-binning" (3x3=9, hence the nona).

    • Pixel binning is a fancy term for combining groups of pixels to gather more light. The result is a brighter—though lower-resolution—photo that hopefully has less noise.

    • Binning isn't your average, everyday downsampling. All of this pixel partying happens at the hardware level, eliminating conversion errors.

    • Here's an unusual thing: this camera module takes up a lot of lateral ... space. Samsung is so proud of this particular camera that they advertise it right on the camera bump. Let's see what's inside.

    • How do you fit a stack of "zoom" lenses into a smartphone that's only 8.8 mm thin? Samsung says: turn it sideways. Instead of focusing your image directly onto the sensor, this camera uses a prism to bounce the light sideways at a 90-degree angle.

    • It certainly is impressive! After passing through the prism—which has its own optical image stabilizer—the image barrels through a sliding box full of telephoto lens, and finally hits the sensor mounted at the end of the tunnel.

    • The lens itself is good for a (fixed) 4x magnification—the rest comes from a combination of sensor cropping and binning (48 megapixels pared down to 12) and standard digital zoom, to get to 100x.

    • With the prism lifted out, we can see the copper coils and magnets surrounding it, and the tiny white bearings on the supporting bracket. The prism moves back and forth against that bracket to compensate for your shaky hands.

  7. Samsung Galaxy S20 Ultra Teardown: step 8, image 1 of 1
    • With all shields down, we can get a better look at the silicon hiding beneath:

    • Samsung K3LK4K40BM-BGCN 12 GB LPDDR5 RAM layered over Qualcomm 865 SoC

    • Samsung KLUDG4UHDB-B2D1 128 GB UFS 3.0 flash storage

    • Qualcomm SDX55M 2nd-gen 5G modem

    • Skyworks SKY58210-11 RF Front-End Module

    • Qorvo QM78092 Front-End Module

    • Maxim MAX77705C power management IC

    • Qualcomm QPM5677 and QPM6585 5G power amplification modules

  8. Samsung Galaxy S20 Ultra Teardown: step 9, image 1 of 1
    • But wait! Flippin' the boards over reveals even more flippin' chips:

    • Qualcomm SDR865 RF Tranceiver

    • Murata KM9D19075 Wi-Fi & Bluetooth Module

    • Qualcomm PM8250 power management IC

    • Qualcomm PMX55 power management IC

    • Qualcomm PM8150C power management IC

  10. Samsung Galaxy S20 Ultra Teardown: step 11, image 1 of 2 Samsung Galaxy S20 Ultra Teardown: step 11, image 2 of 2
    • And the bonus bonus chips:

    • Qualcomm PM3003A power management

    • NXP Semiconductor PCA9468 high-current fast charger

    • Cirrus Logic CS35L40 audio amplifier

    • Cirrus Logic CS40L25 Class D haptic driver

    • Our oversized suction cup makes a second appearance for this stubbornly adhered battery. That, plus some isopropyl alcohol insertion, are just enough to free it.

    • It's gruesome glue, and almost looks like Venom got a hold of this battery and just won't let it go.

    • This ultra-large battery boasts 5000 mAh running at 3.86 V, for a total 19.30 Wh.

    • That's a huge increase over its contemporaries—most notably the iPhone 11 Pro Max at 15.04 Wh, and the Galaxy Note 10+ 5G at 16.56 Wh.

    • Looking around the fringes of the phone for any hiding bits, we find a millimeter-wave antenna stuffed along an edge next to a copper heat diffuser—a very familiar arrangement.

    • That 120 Hz screen refreshes so much faster, but comes off about the same speed as before (slowly and painfully).

    • Comparing this to the Note10+ display, there's no obvious indication that this one has the faster refresh rate. It does look a bit more streamlined though—Samsung managed to consolidate down to a single ribbon cable, simplifying repairs a bit.

    • On-board silicon includes:

    • Qualcomm QBT2000 3D Sonic Sensor controller

    • Samsung S6SY79AX Touchscreen Controller

    • Winbond W25Q80EWUXIE 8 Mb Serial NOR Flash

    • Appropriately, the codename for this "space zoom" phone is.... Hubble. As we all know, the Hubble space telescope worked perfectly at launch, never needing a single repair.

  15. Samsung Galaxy S20 Ultra Teardown: step 16, image 1 of 1
    • Samsung continues to push boundaries, but this time in a less bendy form-factor. While smartphone designs have slowly converged on the same giant black glass slab, we found some interesting things packed inside the S20 Ultra!

    • It would be easy to dismiss things like 5G (that only works one block at a time in the world’s biggest cities) or crazy-high-pixel-density and periscope cameras as gimmicks, but sometimes novel little hardware additions turn into pretty big deals (selfie cameras, anyone?).

    • In a world of iterations and safe bets, it's refreshing to see Samsung continue to do what Samsung does best: pack phones full of zany technology and see what sticks.

    • Unfortunately, Samsung isn't pushing any boundaries repair-wise, as evidenced by this phone's repairability score...

  16. Final Thoughts
    • The fasteners, all identical Phillips screws, only require one driver and can't be mixed up, simplifying repair.
    • Many components are modular and independently replaceable, but the missing headphone jack means double duty and wear for the USB-C port.
    • Every repair starts with painstakingly un-gluing the fragile glass rear cover.
    • Replacing the glued-down battery is tougher than ever, especially with board interconnect cables to work around.
    • All-too-common display repairs require either a complete teardown or replacing half the phone.
    Repairability Score

Interesting that the S20 Ultra has a lower repair score than the iphone 11 (pro) but still the iphones get much hate for being not good at repairability.

It’s a funny thing where android phones are harder to repair, but they don’t actively try to discourage it with software like Apple does. Apple, despite being fairly easy to get into, still uses proprietary screws and displays a warning / disables certain features when users install a third party battery or screen.
