Edit Step 1 Samsung Galaxy S5 Teardown  ¶ 

  • It's good to have a galaxy to play with, 'cause we're gonna need a lotta space for all this hardware:

    • 5.1” Super AMOLED display (1920 x 1080, 432 ppi)

    • 16 MP rear-facing camera with 4K video at 30 fps; 2 MP front-facing camera with 1080p video and wide-angle lens

    • Sensors for fingerprint, heart rate, gestures

    • 2.5 GHz quad-core Snapdragon 801 processor, 2 GB LPDDR3 RAM

    • 16/32 GB internal memory, plus microSD up to 128 GB

    • LTE, NFC, Bluetooth 4.0 BLE, Micro-USB 3.0, 802.11/ac MIMO Wi-Fi

Edit Step 2  ¶

Edit Step 2  ¶ 

  • Our initial sensor sweep reveals no life signs—just lots of life-sensing equipment.

    • From fingerprint scans to interpretive gestures, this phone shows signs of high-level interaction with an advanced civilization. Also, dimples.

  • Visible beneath the 16 megapixel rear camera: a heart rate monitor. Useful when you need to monitor your heart rate from your smartphone. So basically all the time.

Edit Step 3  ¶

Edit Step 3  ¶ 

  • Port ho! This silver bay is a Micro-B USB 3.0.

  • And it's open. Down to the battery at least. Tears of joy fall silently around the teardown table.

  • Peeling the back off this phone is easier than peeling a banana; the only tool required is an opposable thumb.

    • Despite negative reviews of the case design, the ease of removal is a big plus for us.

  • What's that, no battery?

    • Samsung seems to be promoting the DIY lifestyle. Not only is this battery replaceable, it needs to be user installed. That deserves an internet high-five.

Edit Step 4  ¶ 

Image #1

Edit Step 4  ¶ 

  • No need to hitchhike to the edge of this galaxy to find the back case; it's free and clear.

  • We're guessing that this strange shape in the case is not a remnant of space creatures, but a rubber gasket. Samsung chose the minimalist's approach to water and dust resistance over more problematic methods.

    • So don't go taking your new phone to the dunk-tank. If you do—or better yet, before you do—get yourself a Thirsty Bag.

Edit Step 5  ¶

Edit Step 5  ¶ 

  • We briefly glance at the warnings as we pull the battery out of its fancy packaging.

    • Questionable batteries will apparently explode when installed.

  • This is a batty 3.85 V, 10.78 Wh battery. Samsung touted a better battery-saving mode, but failed to specify the life of this guy in its advertising—listing the battery spec as 2800 mAh.

    • This is a slight upgrade from the S4's 3.8 V and 2600 mAh (9.88 Wh) battery. Advertised at 7 hours of talk time, and up to 12.5 days of standby.

  • We install the new battery. Then, we take it back out. This teardown has places to be and they're under that battery pack.

    • For those keeping track at home, that took a grand total of 10 seconds. Beat that, HTC.

Edit Step 6  ¶ 

Image #1

Edit Step 6  ¶ 

  • Samsung has stacked the deck in our favor—the deck of microSD + SIM cards, that is.

  • "Galaxy S5" may be catchier, but for those who prefer a more formal designation, SM-G900A is the model number you seek.

  • What's behind door number R1?

    • So far as we can tell now, just random connectors, and certainly not the screws we were hoping for. Stay tuned, because we've got a feeling this will be important...

Edit Step 7  ¶ 

Image #1

Edit Step 7  ¶ 

  • Suddenly, things are looking grim. The S5's forefather, the S4, took to the teardown table like a protocol droid to an oil bath.

  • This time though, it seems the entire display assembly stands in the way of any further tinkering.

  • With no other recourse, we call in our fixer muscle, iOpener and Opening Pick—perhaps better known by their street names, Heat and Force.

  • This is looking dire. What happened, Samsung? I thought we were friends.

Edit Step 8  ¶ 

Image #1

Edit Step 8  ¶ 

  • Time for the final pry op—

    • ...aw, nuts. CABLE.

  • Cable booby traps are like finding a pit of snakes between you and the treasure you are after. To make matters worse, Harrison Ford is nowhere to be found.

  • After spudging past the cable, we begin to free the display assembly. Unfortunately, Samsung seems to think that the only way to get into this phone should be glass-first.

Edit Step 9  ¶ 

Image #1

Edit Step 9  ¶ 

  • With the display thusly removed, we just have to convince it to part with its home button. We let our plastic opening tool do the talking.

  • Say goodbye to the sticky adhesive tape holding the screen down. Reinstalling your display will most likely require a fresh set of adhesive.

  • This little display assembly cable has a lot of bits to ferry. It's helped out by a Synaptics S5100A touchscreen controller.

  • This is a fairly radical change in design for the S-series. We're used to seeing internal components riding on the back of a large display assembly. The S5 turns this on its head and sandwiches the components between the display and the battery, in their own difficult-to-access compartment.

Edit Step 10  ¶ 

Image #1

Edit Step 10  ¶ 

  • Oh Samsung, we were hoping we might be going about this all wrong. But alas, here are the screws we needed—on the other side of the phone. Sigh.

  • We've reached a point of debate on Galaxy nomenclature. The consensus says we're removing the midframe from the um, midframe.

  • Confused? Yeah. We were, too.

    • Here's the deal: after peeling off the rear case, you encounter a midframe. And between that (first) midframe and the display assembly, there's this second midframe. So there you have it: double the midframe.

Edit Step 11  ¶ 

Image #1

Edit Step 11  ¶ 

  • So, to recap:

    • On the left we've got the interior midframe, with the motherboard and daughterboard

    • On the right we've got the exterior midframe, with a plethora of spring-contacted components

  • We're already on a first-name basis with the other bits in here: headphone jack, speaker, buttons, etc.

    • Identity crisis averted. Repairability crisis, TBD...

  • Also now visible, just beneath the massive rear-facing camera, Samsung's all-new heart rate monitor, powered by the Samsung SM-G900S biosensor.

Edit Step 12  ¶ 

Image #1

Edit Step 12  ¶ 

  • Remember door number one's mystery connector? Surprise—it was the home button cable!

    • This discovery is a bonus to the S5's repairability (and a classic lesson in the need for repair manuals)—disconnecting the home button cable from the start would have made the display removal much easier, and will certainly aid in reassembly.

  • Present and accounted for is the expected fingerprint scanner tech. The control chip is labeled 1200P E43F2.

Edit Step 13  ¶ 

Image #1

Edit Step 13  ¶ 

  • Near the center of the Galaxy we find a black hole the motherboard. With the hard work done, we pop it out and start scouring for evidence of intelligence.

  • Our first sign comes via the camera.

  • Anxious for a staring contest, we use our trusty plastic opening tool to pry it out for a better look.

Edit Step 14  ¶ 

Image #1

Edit Step 14  ¶ 

  • On the left, we have Samsung's 16MP 1/2.6” rear-facing camera.

    • Touting new, faster auto-focus, this camera should enable users to finally catch a real UFO with photographic evidence.

    • Safe and sound in the main cam's backpack is a control chip: QDA41 L1010 R412.

  • Standing next to the main camera is the Hobbit selfie stunt-double, a 2.0 MP front-facing camera.

    • This little wide-eyed wide-angle lens shoots with a resolution of 1920 x 1080.

Edit Step 15  ¶ 

Image #1

Edit Step 15  ¶ 

  • Some galaxies have stars. Others have chips:

    • Elpida FA164A2PM - The same 2 GB RAM package we found in the HTC One (M8), and different from the 2 GB Samsung chip found in Chipworks' analysis. Quad-core 2.5 GHz CPU likely layered beneath

    • Samsung KLMAG2GEAC-B0 16 GB on-board memory

    • Avago ACPM-7617 multi-mode, multi-band RF front end

    • Murata KM4220004 (likely Wi-Fi module)

    • 1412 (C1N75R UMR3) (C1N78B YMP4)

    • Maxim Integrated MAX77804K (System PSoC) and MAX77826

    • STMicroelectronics 32A M410

Edit Step 16  ¶ 

Image #1

Edit Step 16  ¶ 

  • SWEP GRG28 antenna switch module (thanks Chipworks)

  • Qualcomm WTR1625L RF transceiver (another encore from the HTC One M8) and...

  • Qualcomm WFR1620 receive-only companion chip

  • Qualcomm PMC8974 power management IC

  • Lattice iCE40 LP1K low-power FPGA

  • Invensense MP65M (MPU-6500M) gyroscope/accelerometer

  • Qualcomm WCD9320 audio codec

  • SIMG 8240B0 mobile HD-link transmitter and NXP 47803 NFC controller

Edit Step 17  ¶ 

Image #1

Edit Step 17  ¶ 

  • With the motherboard out of the way, we find ourselves short of parts. All we have left is a lonely little daughter board.

  • Home to the charging port, a closer examination of this daughter board reveals cables for the bottom buttons, as well as a smattering of ICs:

    • Cypress CY8C20075-24LKXI CapSense capacitive touch-sensing controller

    • RFMD RF1119 antenna controller

    • S1221 primary microphone

Edit Step 18  ¶ 

Image #1

Edit Step 18  ¶ 

  • Samsung Galaxy S5 Repairability Score: 5 out of 10 (10 is easiest to repair).

    • The battery is incredibly easy to remove and replace.

    • The display is now one of the first components out, making replacements a little faster. However, it is held in with a significant amount of adhesive and requires very careful and persistent prying and a considerable amount of heat to remove without cracking the glass or cutting cables.

    • Once you get the device open, several components are modular and fairly easy to replace, such as the cameras, headphone jack, vibrator motor, and speakers.

    • Replacing anything other than the battery requires first removing the display, risking extra damage on the way to a repair.

what is the 802.11ac chip?

Ehsan Nourbakhsh, · Reply

it's the wi-fi chip. 802.11 is a norm at IEEE ;)

Thomas,

was the lcd glued to the frame? i mean that reddish foil, did it come

off easily without heating it up? thanks

elvirs, · Reply

LCD and touchscreen is fused together. Which reddish foil are you referring to?

adnan amru,

I think he means the copper-coloured backside of the display assembly. And I have the same question, was the backside of the display assembly glued to the midframe, or was it just the sides that were glued to the frame?

Audun,

How come iphone 5s scored higher than Galaxy S5? At least S5 is easier to replace battery without any difficulties.

Thomas, · Reply

Because for s5, any PROPER repair will involve opening up the display module, which destroys the waterproof LCD adhesive. Special reassembly and functional test procedures are needed to restore the phone to its original performance. On an iPhone 5s no such problem is present.

Tom Chai,

@Thomas- For the iPhone 5s, you have to disconnect the home button (and fingerprint scanner) from the front display assembly as you open it, but opening it is trivial. The only worry is ensuring you don't snag the home button cable connected to the main board. This isn't super hard but requires some dexterity that makes a DIY repair much harder.

For the S5, it appears you have to heat the front of the display (at least the edges) and gently and rather expertly apply force to lift up the screen assembly. Not only do you have to do that to get the screen out for a screen replacement, you have to do that for ANY internal repair. There is a very high risk of breaking the screen doing this. Given that this is by far the most expensive component, that's a substantial risk if all you want to do is replace the camera/speaker/etc.

My guess is that Samsung decided on this approach to keep it water proof/resistant, but it greatly complicates any repair, ones that would be trivial on other Galaxy devices.

blank, · Reply

@thomas adhesive like this is an automatic lowering and although it has a replaceable battery, that won't help if anything else breaks.

Ashley Ryan, · Reply

How is access to the plastic 'string' piece that connects the USB/charger port cover to the frame? I'm asking as I can see this piece becoming a common break in the coming months. Hopefully it doesn't involve a disassembly of the phone to change the string/charge port cover.

Jon, · Reply

The charge port cover is held on by one screw and a small plastic cover piece. It is trivial to replace broken covers so this will probably be a really cheap, easily sourced replacement part. I may pick up a 10-pack for my own S5. Feel like I will need that many.

PMDR,

thank you for help us

Hello guys!

I really need help here. My galaxy S5 doesn't pick up my SD Card anymore. It work for few days at first use but now it doesn't. I check my SD card on other phones and tried other SD Cards too, it doesn't pick it up. any suggestion guys?

Google's Android Device Manager helps you to remotely locate your device and wipe your phone’s data, if it is lost or stolen. It also provides protection to your lost phone by enabling remote locking. I found this info here, http://www.spinfold.com/android-tricks-a...

I cut the cables to the "back" and "recent apps" buttons. They aren't as sensitive anymore, but fortunately they still work. I also ripped some of the foil on the back of the screen, but I haven't noticed any negative effects from that.

madison,

So.. I have a G900V. I cracked the screen, followed by a trip to the toilet :X

Ever since, I cannot make calls, rarely sms, but have great data?? Every app, sensor, sim status etc says I have reception, but the dialer just hangs at 0:00... Pulldown indicates "No Service" at the bottom. I had a similar problem with the s4, turned out to be one of those micro coaxial type antenna cables/connection. Have any ideas?

Rick Stanley, · Reply

My version of the SM-G900F has _two_ high-frequency cables going from the motherboard to the USB module. One blue (wired like yours) and one grey (wired from the center of the motherboard, left of the blue one, through the "crack" near the top of the duct the blue one follows and exits at the bottom of the duct turning left and connecting beneath the CY8C20075-24LKXI.

I had to replace the display _and_ the USB module (damaged it while disassembling the phone).

Question: Now I have replaced both display AND USB module - and the phone ALMOST works. The problem it experiences is a very much lacking connectivity in terms of phone and 3/4G internet. Wireless does work. My question is thus, could I have bought an incorrect USB module? The new one has all the same connectors. Could I have forgotten something else? Is there a gnome in my phone? Are the skies falling?

If you happen to know - or if you happen to be a smart Alec that happens to be right as well, please chip in - I'd love to have my phone ok. :)

I just replaced the charging port in my s5, taking great care to not break anything. However, the touch screen doesn't work now. Any suggestions?

inquisitionlalia, · Reply

Is there any way to check if the back body or mid section of the s5 is bent?

I think my s5's might be bent and I am not sure of how i can verify this.

The reason i ask is the lcd screen cracked while it was in a protective case and withe a glass screen protector on. The phone was in my pocket when it cracked.

What is this dark grey material between the corner of the exterior chrome frame and the lighter grey frame inside? In case of shock on the corner resulting in a slight deformation,could it potentially damage the water resistant integrity of the phone?

Is there only one camera replacement part for this phone, or are there multiples? We have seen multiple models and have to figure out each time you open a new one, which one you need. Is there a way to find out which one you need prior, and possibly where to order them?

At the intersection of the SWEP GRG28 antenna switch and the Qualcomm WTR1625L RF transceiver the is a small gold female connector....what size is it? It's smaller than M, maybe O or P?? I wonder why the change from all previous galaxy models that use the FMA/M CONNECTOR. I know it's an inconsequential tidbit to most but if you have the extra time I'd appreciate it.

What type of adhesive is holding the screen in place. After replacing a componant, will it just be a matter of reheating the existing adhesive and replacing the screen?

you can add any glue.. anyway if you heat to remove glue works ok

I have to say, 5 out of 10 is far too forgiving a score. I would give it a 3. screen-replacement is a definite red mark. i think i could do 20 s4 screens in the time it takes to do one s5. Those used to previous sasmung galaxy repair can easily find themselves breaking the home button cable if they don't have forewarning. placeing screws behind the display seems very deliberate and cynical on the part of the design team.

this also means that you cannot purchase a new screen with the frame included. you must use the phone's existing frame and align it EXACTLY right. (pay extra to get pre-cut industrial glue). the first s5 i did, the new glass wouldn't align with the steel mic mesh. i had to spend over an hour grinding down the mesh!

i cant beleive samsung would do this to me :(
