  1. 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:
    • 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.

    Which model is the teardowned S20 Ultra?

  2. 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?

    YAY! I hate Bixby anyway!

  3. 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!

  4. 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.

    • 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.

  5. 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.

  6. 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.

    • With all shields down, we can get a better look at the silicon hiding beneath:

    • Qualcomm PM8150C power management IC

    • Qualcomm QDM4870 front-end module

  9. 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.

  10. 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:

    • 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.

  11. 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!
    • 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...

  12. Dernières pensées
    • 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.

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.

TheFlying SpaceSpider - Réponse

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.

Andy Miller -

Also a funny thing that while an Apple product would be theoretically easier to repair, you would have to get parts from another broken apple device to fix the product since Apple refuses to sell spare parts unless you go through their procedure as an authorized repair store.

Brendan Mendonca -

iPhone’s don’t get hate for the repairability. They get hate for what Apple tries to do to stifle 3rd party repair. That is all.

Which model is this? The teardown is titled the Galaxy S20 Ultra but points out a Qualcomm 5G modem. So this must be the 5G model?

Thanks!

Hi Jack,

All Galaxy S20 models are 5G capable, and the S20 Ultra includes mmWave support.

Mine’s shattered too! From a tiny drop, in a case…

After replacing it spend $1.32 on ebay to cover the camera bump with a glass protector and no more replacing the camera bump.

Very complex disassembly. I do recommend replacing “5000 mAh” with “5 Ah”. That is less zeros and one less character.

rayramirez - Réponse

Bad idea as time and time again the public has not proven smart enough when it comes to numbers. Think of the A&W 1/3 pounder, which failed because people could not figure out 1/3 was greater than 1/4. 5000mAh looks bigger than 5Ah to the average consumer, and Samsung does not want to risk relying on people having to notice the lack of the “m”.

Brendan Mendonca -

That is a very complex disassembly. I do recommend replacing “5000 mAh” with just “5 Ah”. That is less zeroes and one less letter. When lithium ion cells has low storage, using “mAh” was valid. But after passing the 1000 mAh level which is a full amp-hour, it is silly to read so many zeros. It is as bad as stating your height in millimeters (mm), especially if you are taller than one whole meter.

Perfect one to ask this question: I accidentally shoved the ejector pin into the hole in the bottom of the phone (microphone opening?) instead of the SIM card tray hole… Do you think that I could have damaged anything?

Don’t worry! You most likely did not damage anything. Here’s a more thorough explanation.

Hi, thanks for this magnificent teardown.

I hear a strange sound when i move my unit around, it looks like a moving part sound and it is on the cameras side. The sound go away when i open camera App!

So what do you think of is the issue? which seems to me is the prism.

And regarding 5G, i do have five blocks of 5G in my city. And the speed test results are:

Any help would greatly appreciated.

Can you tell me if the exynos version of the S20 Ultra have mmwave antennas?

William - Réponse

Is the USB C port weak? I've had multiple phones with charging ports that go wobbly and I want to see them build a better one. I think previous versions just had a port soddered in instead of a more sturdy solution.

Can the top glass be replaced on its own if the display isn't damaged?
