After the Galaxy Note7’s fiery exit, Samsung is hoping to bring a different kind of heat with the Galaxy S8 series. We've carefully dissected and analyzed the Galaxy S8+—and now we turn our attention its smaller twin, the Galaxy S8.

Does the S8 have what it takes to blast off without blowing up? There's only one way to find out — Ladies and gents, it is teardown time.

This teardown is not a repair guide. To repair your Samsung Galaxy S8, use our service manual.

  1. Samsung seems to have gone all-out to provide the same smartphone experience regardless of your screen size preferences, and the Galaxy S8's specs bear that out. Any of this look familiar?

    • Dimensions aside, the S8 fairly identically clones the look of the S8+. Features include:

      • Speaker grille and microphone hole

      • USB-C charging port and headphone jack (Apple: 0 Samsung: 1)

      • Pulse reader/flash assembly

      • Rear-facing camera

      • Fingerprint reader

    • The S8 is a safe evolution on the S7 Edge—proportions, camera and sensor package location, and size are all fairly on par.

    • The Galaxy once again rocks the glass-on-glass design, making our lives difficult. We heat the heck out of this panel and apply plenty of prying picks.

    • Once we get an edge open, the iSclack helps us crank through the rest of the gnarly adhesive (which will need replacing upon reassembly—*groan*).

    • And we're in—to an S8+? This guy looks pretty darn identical.

    • The fingerprint sensor lives in the rear case, somewhat controversially placed. Using the thing (with your right hand) requires blindly stretching and blotting out the camera...

    • The good news is that this sensor is modular and can be popped right off its adhesive for replacement. All it takes is a little heat and a good push.

      • No word (yet) whether software locks (à la iPhone 7) will prevent a replacement from functioning.

    I have replaced the finger print sensor and it remained fully functional.

    • As with its S8+ sibling, the S8 employs some sweet hardware multitasking. The speaker/antenna array, and antenna/NFC coil assembly, do double duty as the phone's midframe.

    • Also like the S8+, the NFC antenna presumably does an additional job, spoofing MST to use Samsung Pay at any card reading checkout location.

    • We're almost running out of things to say here—the rest of the phone looks pretty much like the S8+ too, down to the wee pancake vibrator. It's like someone left the S8+ in their pocket on laundry day and it came out of the wash slightly shrunken, but no worse for wear.

    • You'd think that after Samsung's less than stellar battery record, they'd have a quick eject system for these little bombs packs. And yet, this cell is firmly (and we mean firmly) adhered.

      • And it's not like it's especially hard to have a removable battery—it's done all over the phone world.

    • The Samsung-branded battery clocks in at 11.55 Wh—comparable to the Google Pixel's 10.66 Wh, but dwarfing the (slightly smaller) iPhone 7's 7.45 Wh battery.

      • The capacity comparison may look impressive, but reports seem to suggest that the actual performance is nothing to cheer about.

    • The I/O board connector is under the motherboard in these late-model Galaxy phones. Because why not make things harder?

    • The motherboard itself pops out with relative ease, giving us a peep at that now-Samsung-standard heatpipe.

    • The I/O daughterboard configuration matches the S8+ right down to the modular headphone jack.

    • Since we've already gone through the camera shenanigans, let's get straight to the chips.

    Add Comment

    • We checked the genetics chips in the S8 to see if it is truly a smaller twin of the S8+:

      • Samsung K3UH5H50MM-NGCJ 4 GB LPDDR4 RAM layered over the MSM8998 Snapdragon 835

      • Toshiba THGBF7G9L4LBATR 64 GB UFS (NAND flash + controller)

      • Qualcomm Aqstic WCD9341 audio codec

      • Skyworks 78160-11

      • Avago AFEM-9066

      • NXP 80T71 NFC controller

      • Silicon Mitus SM5720 Interface PMIC

    Add Comment

    • On the opposite side we find:

      • Murata KM6D28040 Wi-Fi Module

      • Qualcomm PM8998 (similar to PM8920)

      • Qualcomm WTR5975 RF Transceiver

      • Avago AFEM-9053

      • IDT P9320S

      • Maxim MAX77838 companion PMIC (similar to MAX77829)

    IDT P9320S should be for wirless charging

    • That's it for the vanilla S8. If you haven't already guessed, we've got a more detailed breakdown of the S8+, so check it out if you haven't already.

    • With that, let's give the Galaxy S8 its repairability score.

  4. Final Thoughts
    • Lots of components are modular and can be replaced independently.
    • The battery can be replaced, but tough adhesive and a glued-on rear panel make it unnecessarily difficult.
    • Front and back glass make for double the crackability, and strong adhesive on both makes it tough to access the internals for any repair.
    • Because of the curved screen, replacing the front glass without destroying the display is extremely difficult.
    Repairability Score
    Repairability 4 out of 10
    (10 is easiest to repair)


With the release of the Samsung Galaxy S8 and S8+, Samsung has begun building new "Wizard Lounges" at which Samsung officials can personally tell you "your phone is broken, buy a new one!"

I would like to know how heavy the battery is compared with the S7 battery and how big (volume) it is

Henning Holthusen - Reply

From memory, (did a teardown just recently,) the S8 Battery is significantly heavier than an S7 battery. It is quite a bit thinner however, so the added weight must be caused by the internals. I'm no expert on battery composition but I know for sure that S8 batteries are much more durable from a repairers point-of-view.

Harry Rowse -

Am I right in observing that the charging port flex module no longer has button ribbons that fold around the mid-frame and underneath the glass?

If so... techs everywhere are rejoicing right now.

kyle - Reply

Correct! That alone makes for a significantly more repairable phone. Once you get an S8-series phone open, removing the daughterboard/charging port is totally straightforward.

Jeff Suovanen -

So, I know a lot of you are going to be !#^&@@, but I got my S8 in the mail yesterday. I cracked the back glass about 45mins ago. Do any of you have any idea how much it is going to cost to fix it?

Johnathan Jones - Reply

Wow. Well, heres what I'd say. Your waterproofing is gone. Repairing it yourself is a no go because a replacement back is $100 and I could only find one seller on eBay.

Best send it to Samsung, keeping your waterproofing and warranty.

GG MALL Have already selling the S8 back glass one month before the galaxy s8 release LOL

My back glass got broken so it is repairable or not ? samsung S8

Abhishek Yadav - Reply

Is there any way to retrieve storage(photos, songs) if the phone was destroyed? Like taking it a apart

Gustavo Padilla - Reply

Also broke the back glass 1st day I had it. Thinking major design flaw, because I haven' t even dropped the phone yet! Can't count the number of times my S7 flew off my lap as I got out of the car without breaking. Don't know exactly when it got broken. Only thing I can think is if I set down the oculus with the phone still in it and the extra weight broke it.

Ed Burie - Reply

Have had my S8 4 days and front glass broke today. I was sitting in chair at a meeting using the stop watch and the phone slid off my lap onto a carpeted floor. It wasn't a long fall - was very close to the ground when it happened and it hit softly. I can't find replacement glass parts anywhere online and after reading this, it sounds like I should go the insurance route instead.

drkandcjk - Reply

Amazon offers oem replacement parts, in large selections. I was able to purchase a new back glass & new front glass (w tools and a roll of adhesive included) both for under $45. Roughly $20 per item.

Melissa Shupe -

I encounter the same issue less than two weeks of new S8 slipped out my hand with a low drop and craked along the side. Got insurance and replacement was for only $49.99 which I was told there was not a service provided here in las vegas. I was mad as heck !!! and got my refund insurance money back and cancel policy. I checked around town for replacement and was told it would cost over $150.00 for screen replacement which was crazy ridculous. As of today I still using my racked screen . Today I was told that I need a mircophone/speaker fixed and I hate to see the cost for that. These new slim S8, S9 and new cell looks great but easy to break and not worth the price for replacement.

There is a dirt gets into my upper mic hole, and I cannot take it out. It drives me crazy. If I see the structure of the mic canal here, the mic and the membrane do not face directly to the outside, but make a 90° angle. So can I assume if the canal is safe even if a tusk enters it?

Bogdan Lol -

Thanks Bogdan for your riveting reply. The glass isn't easy to remove on its own, but it is possible. It is much easier once you've gutted the phone, as you can bend and twist the frame ever-so-slightly to loosen the adhesive on the device without compromising the LCD. The phone definitely performs well, but its build quality might be a little bit underwhelming to anyone with an eye for that sort of stuff. For the average consumer, eh, who cares about a bit of lag?

Harry Rowse -

Had phone for a couple weeks. Never dropped and take great care of it. Already has a crack on the back around the center of the screen. Maybe from bumping into my keys that might have been in my pocket. How did Samsung think this would fly? Leaving on my desk untouched till I get a super case for this thing. Very frustrating.

flibbertig155 - Reply

i feel like shame on you for having a full glass phone and not having some kind of case from the get :( but the main reason that they make the rear panel glass is to enable easy wireless charging. A metal backing would not be able to freely wireless charge.

Mike Craanen Jr -

is there any heat pipe ..... is it more effective than previous models ... specially on VR

jihad khorfan - Reply

Yep the heatpipe is still around, you can see it in the second photo on step 7 under the motherboard, looked about the same as the S7 pipe to our eyes.

Sam Lionheart -

Funny to see all these (obviously non LG) users complain about the "difficulties" of using a rear-panel-located button. Here's a simple trick that might make you feel stupid: step 1) with your right hand holding the phone, place your index finger on the rear edge of the phone (the left side if the screen is facing your--the side the fingerprint reader is closest to); step 2) slide your finger until you feel the fingerprint sensor. VOILA!! No need to smudge up your camera.

The curved screen really has no advantage, and actually catches reflections much worse.

Peter Zpat - Reply

I had this phone for 2 days and it slid off of every surface I placed it on, unless the surface was perfectly flat . This is a defect in the design. It is too slippery to use without a case. Now I have a cracked back case and have probably lost wayerproofing. I am going to complain to Samsung.

Ralph - Reply

Hey Ralph!

I have noticed some S8 handsets do actually have concave rear panels. It is very very slight, barely noticeable to the naked eye. The only way I've tested it is with a small ball bearing. The bearing would always roll directly to the center of the rear panel. Because of this, the phone sometimes builds up an air cushion, making it slide like an air-hockey puck. A case for these phones is an absolute must! They are 95% made up of extremely fragile glass, probably intentionally. If Samsung refuses warranty, and offers service, do your best to decline, and check out a local third party repair store. Rather give local business a chance over Samsung!

I have dropped my device 2 times with basic Verizon case that came with it and worthless screen protector. Sounds like I got lucky no cracks. I ended up putting qmadix liquid screen protector $39 since regular tempered glass wouldn't adhere. I like the surface the qmadix has made 9H Sapphire hard seams last 2 weeks no scratches,less smudges, easy to apply no bubbles and antimicrobial!!!

Can I change the frame alone without having to change the display with it? I ask because i just dropped it and even though it has a case the frame is scratched and i would like to change it but i can’t find a frame without the glass.

Anyone try adding a magnet plate for the magnetic carmounts under the back glass? Would it fit?

Is there enough room to add a magnetic plate under the back glass in order to use it with a magnet car mount?

I know it would interfere with wireless charging, just interested in know if one would fit under there.

I have my s8 phone and today it slid off and the front glass has smashed (Touch screen) and i wanna know how much it costs me and which is the best store to do that

wasfi shari - Reply

Samething happened to me a few weeks of purchasing new S8 last year. I was told over $150.00 for replacement screen which is crazy. Today trouble shooting told me my speaker not working and I cannot imagine the cost. New design cells is easily to break and costly . After this contract done or if I decide to pay off ahead of time I’m going back to an older cell and doing prepay no contract or track phone. done with all cell provider which a big ripoff and lies.

@boosnie Hair dryer and patience will work fine. It takes quite a bit of heat to soften the glue securing the rear cover. Remember, this is a teardown, not a guide—the guides are over here. ;)
