Introduction

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.

  • 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.

Image 1/2: 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.

  • 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...

  • 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.

  • 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.

  • 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.

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!"

+1 for the best review I have seen on this so far.

Very nice Photography!

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

Henning Holthusen - Reply

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.

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. http://www.ebay.co.uk/itm/100-OEM-Origin...

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

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.

I had my 5 day old phone slide out of my hands in the driveway. The back of the phone is smashed and cut me. How do i replace the back?

Sweet mother of jesus--we can replace the usb port without taking off the screen??!! Oh happy day. BTW, ifixit, when removing a camera, DON'T PUT YOUR THUMB ON THE LENS

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?

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.

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.

Javan Pohl - Reply

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.
