Introduction

Hot on the heels of our in-depth teardown of Samsung's Galaxy S7, we bring you another future teardown classic: the Galaxy S7 Edge.

With most dual-flagship releases, manufacturers have been trending toward sharing as many design elements as possible. We're expecting this teardown to be a challenging game of "Spot the Differences."

Join us as we tear and compare the S7 Edge. To keep up to date on all of our teardown exploits, follow us on Instagram, Twitter, and Facebook.

This teardown is not a repair guide. To repair your Samsung Galaxy S7 Edge, use our service manual.

Image 1/3: A quick comparison with last year's Galaxy S6 Edge shows that bigger is in. The S7 Edge also adds that same IP68 rating and expandable microSD slot that we saw in the S7, absent from last year's offerings. Image 2/3: The camera bump is noticeably reduced as well, which may just be a result of the ~~rising sea level~~ extra 0.7 mm of thickness on the S7 Edge.

  • We just had to test out our Edge notifications to show off that curvy OLED. Unfortunately, nobody has our new number.

  • Here again, we have the continuing voyages of the NSEA Protector iOpener, heating up a galaxy near you.

  • The procedure is identical to that of the standard S7: After liberal application of heat, our iSclack and pick combo is super effective despite some extremely stubborn adhesive.

    • Do you remember the days when an easily cracked back panel was at least easily replaced? iFixit remembers.

Image 1/2: Inside, the two devices feature the same camera, flash, general construction, and even antenna positions (although those squiggles are slightly different). Image 2/2: Despite the startlingly similar layout, the curve-boasting Edge is actually less curvy from behind than its standard counterpart.
  • S7 and S7 Edge side by side to compare and contrast: Heavy on the compare, light on the contrast.

  • Inside, the two devices feature the same camera, flash, general construction, and even antenna positions (although those squiggles are slightly different).

  • Despite the startlingly similar layout, the curve-boasting Edge is actually less curvy from behind than its standard counterpart.

    • The S7's back mimics the Edge's front, with a curvaceous rear panel glass. The result is a mirror-universe evil twin situation. But with glass curves instead of goatees.

Image 1/3: Looks like the standardization with the vanilla S7 means some good things for the Edge. Image 2/3: We extract the whopping 3.85 V, 13.86 Wh, 3,600 mAh burner of a battery. Image 3/3: That's 20% more capacity than the already capacious [https://www.ifixit.com/Teardown/Samsung+Galaxy+S7+Teardown/56686#s122917|3,000 mAh battery in the S7]. It seems the tradeoff for a marginally thicker Edge will be longer battery life and less wear from frequent charging. Nice!
  • Good news, everyone! The battery is no longer trapped under the motherboard, like it was on last season's Edge.

Please peel off the cover on the sim/sd card area for us... the pin configuration for the microsd card is of the utmost importance for accessorizing the storage on this phone...

afterfreeze - Reply

I second this, please pull off the metal cover on the microSD card area to expose the pin configuration!

Nicholas Hamilton -

I also came to this article to find out if the microSD slot has the extra row of pins indicating UHS-II support. It would be really helpful if the answer to this question was backed up by a photograph of the microSD card slot pins. Thanks in advance.

    • NXP 67T05 NFC Controller

    • IDT P9221 Wireless Power Reciever (likely an iteration of IDT P9220)

  • Oh, and one more thing.

    • The S7 Edge's tiny heat pipe is nigh-identical to one we removed from an S7. It should afford the same improved heat diffusion to the metal midframe, improving cooling for those extended Samsung Gear VR sessions.

    • The display needs to be removed (and likely destroyed) if you want to replace the USB port.

    • Front and back glass make for double the crackability, and strong adhesive on the rear glass makes it very difficult to gain entry into the device.

    • Replacing the glass without destroying the display is probably impossible.

When taking the phone apart, I assume that naturally you are throwing some if not all of the water resistant (or proof) capabilities behind, or is that not the case? Maybe you can re-waterproof it again, who knows.

Hello and good afternoon Joshua,

I have had to perform the same teardown on my Galaxy S7. After putting everything back together, I wanted to test the same theory. My phone was still very water resistant (I literally dropped it in a sink of water by mistake lol). But I've seriously had no problems with my S7 after. Hope the same success follows your projects. Have a great day!

damon sampy -

There is some discussion as to whether the S7 phones support the extra speeds in UHS-II microSD cards - which would require an extra row of pins in the reader. The preliminary benchmarks of UHS-II cards show disappointing performance below the maximum speed of a UHS-I port, so it is doubtful that the reader is a full UHS-II reader, but it would be nice if the teardown could confirm the pin configuration of the microSD port so we can put the issue to rest...

Jim Graham - Reply

Where is the sd card reader ? does it support UHS-2 ?

Alexandre - Reply

I've already cracked the back glass a little. Does this impact the waterproofness at all? I've been unable to locate just a back plate/glass piece yet as well, but this would be my first time looking.

Zach - Reply

Same question. Bump

Anthony Emma -

It depends on how deep the crack is. But it will certanly apply more preasure in that point under water.

Franco -

The back glass needs to be replaced on mys7 edge, can I go on from the back or the front. Also, your review mentioned replacing the glass would mess up the display.. Does this only apply to the front glass? One last question, where should the back glad be purchased. I see Amazon sells it but it's literally only the glass, no components.

Fred Jameson -

is it possible to use S7Edge battery in S7?

no their different sizes i think

Hey guys, i have one question that is killing me, hope you can help me: accidentally inserted the key to remove the sim tray in the upper mic hole and apply some pressure until realize my mistake, in a brand new s7 edge, i cant identify the mic hole in your pictures, actually looks like is not straight to the mic, is more like a 90 deg orientation, am i right? Thanks for your help, really appreciate your comments

Bernardo Olivas - Reply

i do the same haha i´m a little scared :S

arym06 -

Anyone got back to you on this yet? I too did the same and my main question is whether or not it would affect the water resistance/proof of the phone by pushing the sim removal took through the mic hole.

Steven C -

If you punctured the mic hole, then this does affect the water resistance of the phone. The speaker mesh is like a net across the speaker hole. Since speakers need air to work properly, air can pass through this mesh, but it is fine enough to the point that water cannot pass through as long as it is not over a certain pressure. This is due to the elasticity of water. For example, a jet of water would be high pressure so that would go through the mesh. The same concept applies if you take the phone beyond a certain depth. If you punctured the mesh, then it no longer has the ability to keep water out.

Chris Fanning -

I wish they would switch to black PCB like iPhones... It looks a lot better that way...

Would I have to take the phone apart from the back in order to replace the front glass panel or can it be done from the front of the phone?

Hello! Who knows have motherboards (r4, t, td, l, a) from galaxy s7 edge external differences between each other? can i put any of them in the same galaxy s7 edge or no?

aubhan Baisarov - Reply

The CDMA and GSM variants are very different so beware what screen assembly you put them in. Samsung loves to screw with us and their endless revisions. I accidentally ordered the EU variant of an S6 edge + and I had to use a longer samsung galaxy s4 antenna wire, as the location of the antenna port on charge port is different on the EU and US version. Still managed to make it work with the longer wire. But for a second there I almost lost my guts over it.

whether you can put a motherboard into the frame Snapdragon version of the Exynos version ??? ??? they compatible???

same question, I have a T-Mobile motherboard and a sm-g935F frame with LCD assembly.

I'm trying to get the LCD assembly where's a good place to buy the parts online for good prices not outraged prices

Austin bering - Reply

Sammy charges $260 to replace it. And it will be waterproof again. Buy the lcd on ebay is about $200. Plus you need the adhesive. Best to just send it to samsung.

Jimmy James -

$200 for an s7 edge LCD? where? Last time I Looked it was still up in the 280+ range.

**The display needs to be removed (and likely destroyed) if you want to replace the USB port**

> Looking at the last image it appears the usb pcb is separate from the display and can be simply remove by screws, can you clarify this replacement would damage this display?

Stephen Cooke - Reply

No you cant. The buttons are on the same board, you need to remove the screen to free the 2 captive buttons, then you can unscrew the 2 little screws. You can sacrifice the 2 buttons then its easy

Robert Vasile -

Totally radical idea... I have a Sprint S7 Edge with a cracked LCD. If I were to buy a complete s7 (non-edge) chassis and LCD, would it be possible to transfer my mobo/logic board and guts into the non-edge chassis?
