Nexus 5 Teardown

Published: 31/10/13

Teardown

Introduction

KitKats, snapdragons, unlocked? Google is making us feel like we've got the golden ticket, as we head into Willy Wonka's—er, the Nexus 5. Will Google's latest smartphone be a sweet treat? Or will we be having nightmares of green-haired Oompa Loompas mocking us in rhyme? Join us as we find out.

Hungry for more? Candy-coated, delicious photos on Instagram, bite-sized morsels on Twitter, and a lifetime supply of goodies on Facebook are all yours for the taking.

    • The Nexus 5 is the first phone to ship with the latest version of Android's OS, KitKat. It may not be coated in chocolate, but it has plenty of tasty features:

    • 4.95" full HD 1920x1080 display at 445ppi

    • Quad-core, 2.26 GHz Snapdragon 800 processor and 450 MHz Adreno 330 GPU

    • 2 GB RAM

    • 8 MP/1080p rear camera with optical image stabilization, and 1.3 MP front-facing camera

    • 4G/LTE wireless support, 802.11 a/b/g/n/ac (2.4GHz and 5GHz) dual-band Wi-Fi, NFC, Bluetooth 4.0, and wireless charging

    • 16 GB or 32 GB built-in memory

    • Android 4.4 KitKat

    • Sounds of joy emanate from the teardown factory as we find this Nexus is held together by…plastic clips!

    • These clips are plenty stubborn, but nothing like the headache that a glued panel would be.

    • Agent P.O.T. (plastic opening tool) is deployed to handle this noble mission.

    • We may have cheered too soon—either someone spilled some chocolate syrup, or that's adhesive securing the bottom of the case.

    • Finding glue in your gadget is as much fun as finding chewed gum on your shoe.

    • Luckily this bit of foam adhesive is no match for a few swipes of a plastic opening pick. Our poor fixer souls have seen much worse recently.

    • With the adhesive out of the way, we get our first peek inside this delicious new device.

    That's not spilled chocolate syrup, its melted KitKat bars.

    • Before taking another bite, we pause to chew over the back case:

    • We find conveniently labeled antennas for the Wi-Fi, MIMO, and GPS. It's not quite instructions, but hey, we'll take what we can get.

    • The NFC and wireless charging cables' spring contacts aren't so nicely identified, but are present and accounted for.

    • The vibrator is held in place with only a small amount of adhesive. That means an easy repair, should your phone lose its ability to shake it up.

    • How many licks screws does it take to get to the center of a Nexus 5?

    • No matter the number, our Pro Tech Screwdriver Set is up to the task.

    Are those metal disc magnets in the back cover or perhaps mount points for a magnetic Qi Charger like the Palm Touchstones? That's what the Nexus 4 was missing, and the Orb Wireless charger couldn't hold onto the N4 to save its life.

    Adam B -

    Can you give the dimensions of the battery please?

    Los Ma -

    I'd like to know if the four disks are magnets as well!

    Kelly Wise -

    Can someone please tell me what size the ten identical screws are please, can't find the answer anywhere.

    ross -

    According to this user guide they should be 4 mm Phillips #00 screws

    Sam Goldheart -

    Thanks. Wow, a guide with actual information that's not trying to be funny every other bullet point.

  5. Google gives us the Goldilocks of glue: It's just enough to hold the battery in place, but not too much—the battery can still be removed with minimal prying and virtually no bending.

    • Non-LG manufacturers, take note! We don't want none of your "that ain't possible" funny business when it comes to using glue in devices.

    ALL manufacturers, take note, WE DON'T WANT *ANY GLUE* IN OUR PHONES!

    Maxim R -

    Soldered buttons are no-go too!

    Alexander Tatevyan -

    just FYI I own 2014 Nexus 5 (bought directly from Google Play a month ago) and I got no adhesive glue on my back panel.

    Michael -

    On the Nexus 5 I just tried to fix, the adhesive is pretty solid ! I did puncture the battery. It is now dangerous and the battery should be replaced with a new one.

    Christophe De Wolf -

    It would be helpful to label the NFC and Qi wireless charging spring contacts. I've read multiple reviews from buyers of refurbed Nexus 5s that state the wireless charging doesn't work until they gently press down on the back working up towards the camera and -- snap! Something snaps into place, and the Qi flows as it should. ;) I can't quite tell from the images what is snapping into place on the back. :(

    • LG's 3.8 V, 2300 mAh battery offers a slight jump in capacity over last year's Nexus 4.

    • Google boasts that this pack will keep you sugar-high for 17 hours of talk time, 300 hours of standby, or 7 hours of LTE web browsing.

    • We're pretty sure this warning icon indicates that it's unsafe to let pets smaller than this battery anywhere near it.

    Any chance we'll be able to find a higher capacity battery to fit this space?

    Eoin Murphy -

    Would an LG G2 battery fit in this bad boy?

    Robert Santiago -

    it will not, the LG battery is 7mm longer

    Doug Lynch -

    Whoa! The dog/battery icon is cute, but wth is that swastika-looking thing for?

    Eric Blankenhorn -

    Do you know of any off-the-shelf battery that would fit in this slot and would work with the Nexus 5?

    • Time to break us off a piece of this KitKat phone!

    • The speaker pops out with minimal fuss; it's only secured by few screws and no cables. This is the Nexus standard single speaker, despite the dual grilles.

    • No, this Nexus is not preparing for a BBQ—the second grille is for the microphone. Don't worry; we'll get there soon.

    Can it be modded to have dual speakers? What is in place of the second speaker grill?

    Abul Kasam -

    I really wish there was a compatible speaker that we could replace this one with. It sounds terrible. No, worse than terrible! Anyone know of one that would work? Thanks.

    • We free the Oompa-Loompa-colored daughterboard, and she's got more goodies than the Easter Bunny:

    • Microphone

    • RGB Indicator LED

    • Micro-USB port

    • Speaker spring contacts

    • Antenna spring contacts

    Can the microUSB port be replaced easily, by yourself? Or is it, idk, glued to the board or something?

    Shiv Gunter -

    Glued? It's soldered.

    tjt263 -

    MicroUSB port is connected to USB controller. Where can I find info about (model of) USB controller? What bandwidth of USB bus (maximum possible speedrate)?

    bartgopnik -

    The right part of my daughter board is stuck. Is is glued? I'm afraid I have to replace it, because my microphone isn't working well.

    Joost Adolfs -

    Did you get it off?

    tjt263 -

    What's the difference between the International (D821) & North American (D820) charging circuits?

    Are they interchangeable or cross-compatible? Why/why not?

    Aren't USB standards universal?

    • Less tasty, but more powerful than a Pixy Stick, our spudger makes motherboard removal easier than taking candy from a baby.

    • We quickly spudge away the wireless charging control and NFC board. LG built this little board into an EMI shield assembly that pops in right over the motherboard.

    • This shape reminds us a little of this helpful KitKat map…

    • NFC is the tech behind Google Wallet—one of the Nexus devices' most loved features and one often blocked by carriers. Last month, the rumor mill speculated that the Nexus 5 would feature a Broadcom NFC controller that could eliminate carriers' ability to wallet-block customers.

    • Lo and behold: the Broadcom BCM20793M NFC controller.

    • Also on board: Texas Instruments BQ51013B Qi 1.1 Compliant Wireless Power Receiver

    Remove the SIM tray before pulling out the motherboard to avoid breaking the edge of the frame where the SIM tray slot is.

    • That's some scrumptious silicon! Feast your eyes on these ICs:

    • Sandisk SDIN8DE4 16 GB NAND flash

    • Qualcomm WTR1605L LTE/HSPA+/CDMA2K/TDSCDMA/EDGE/GPS transceiver

    • Qualcomm PM8841 power management IC

    • Broadcom BCM4339 5G Wi-Fi combo chip with integrated power and low-noise amplifiers (the updated version of the BCM4335).

    • Avago RFI335

    • InvenSense MPU-6515 six-axis (gyro + accelerometer) MEMS MotionTracking device

    • Asahi Kasei AK8963 3-axis electronic compass

    Also the pressure sensor is visible here. Maybe worth to mention the tiny metal guy with the hole. :-)

    klo25 -

    Hi, my sim card isn't recognized by device, how can i repair (or replace) the sim card reader ?

    Mario -

    i can see many connectors is it mmcx connector or something else ?

    Can be changed that wifi chip (broadcom BCM4339 )?

    • SK Hynix H9CKNNNBPTMRLR-NTM 2 GB LPDDR3-1600 RAM

    • The Quad-core, 2.26 GHz Snapdragon 800 SoC is layered beneath the RAM

    • Qualcomm WCD9320 audio codec

    • Analogix ANX7808 SlimPort transmitter

    • Qualcomm PM8941 power management IC

    • Texas Instruments BQ24192 I2C controlled 4.5 A USB/adapter charger

    • Avago ACPM-7600 Multi Mode, Multi Band RF power amplifier

    • Qualcomm QFE1100 Envelope Tracking IC

    Soldered buttons??? Excuse me, but this is bullshit! It is a well-known fact, that those parts break easily. So, one would need to replace the WHOLE motherboard in case of button malfunction (at least, not everyone is familiar with soldering technique). Both thumbs down for such a poor design!

    Alexander Tatevyan -

    Does anyone know what the small black and round component is just above (in this picture) the sim-slot? I poked a pin into the phone to remove the SIM but it went past the lever and into this mystery component and damaged it.

    • Out next is the 8MP rear-facing camera.

    • Google has taken some criticism for the less-than-impressive image capture in last year's candy-powered devices. This year they've added Optical Image Stabilization (OIS), but we've only heard tepid reviews so far.

    • The Nexus 5's OIS is powered by an InvenSense IDG-2020 dual axis gyroscope.

    This is not a MEMS camera. It doesn't look anything like the mems camera... http://www.extremetech.com/wp-content/up...

    Steve Garon -

    The Nexus 5 most definitely has no MEMS camera, this was crazy reporting by some blogs based on early leaks about the Sony sensor the Nexus 5 uses.

    Andreas Proschofsky -

    So what is the camera sensor? What's its crop factor vs 35mm, pixel size and sensor size? What's min/max aperture and ISO? Does anyone have a reliable spec sheet?

    Bottomline, isn't it amazing that weeks after launch we're still seeing all different rumours about MEMS or not, but not even the basic confirmed form factor dimensions?

    • We pop out the last of the bite-sized morsels in the Nexus 5:

    • Earpiece speaker

    • Headphone jack

    • 1.3 MP front-facing camera.

    • What a treat! These components were modular and only lightly adhered, seasoned just to our repair tastes.

    In the first image of step 13, what is that small grey piece that sits along the top edge that is next to the small hole in the case edge?

    Dean -

    It's just a channel to direct sound from the mic hole in the case to the mic on the daughterboard.

    Sanya Rajan -

    Can you replace the Earpiece speaker with just removing the Step 9? The Earpiece speaker broke when I droped my phone.

    • Unfortunately, our hopes come crashing down like a blood sugar crash after a candy binge: the front panel is one fused flustercluck.

    • While we saw this in the Nexus 4, we had hoped the LG/Google team could learn the error of their ways.

    • Alas, the front frame, LCD, and glass are doomed to a single shared death sometime down the road to Candy Land.

    • Imagine if one cavity meant losing all your teeth... Talk about a hard pill to swallow.

    • Tucked in at the base of the display, a Synaptics S3350B IC provides touchscreen control.

    does the screen have any SPR(self panel refresh) technology? aka GRAM like the G2. and why are there make and model numbers for most other parts but we dont know the make or model of the screen/panel?

    Doug Lynch -

    This is an LG phone.

    LG is the largest(or close to) LCD manufacturer in the world.

    Why would this panel be made by anybody else. :)

    Maxim R -

    FWIW, I *was* able to separate the LCD from the housing on my device with a broken screen (I ordered the wrong replacement part from etrade -- oops!). Unfortunately this required chiseling away at glued-on glass for 90 minutes over a garbage can.

    If they had chosen to use a lighter adhesive on the screen, they could have dropped the cost of screen replacements from $200 to $150.

    • Nexus 5 Repairability Score: 8 out of 10 (10 is easiest to repair).

    • Very modular design allows independent replacement of several wear-prone components—like the headphone jack and speakers.

    • Only very mild adhesive holds the battery in place, making it fairly easy to safely remove and replace.

    • Standardized screws (ten identical #00 Phillips) simplify repairs and reassembly.

    • The back cover is held in place with plastic clips. Sturdy and rather difficult to remove, but easier than glue.

    • The glass and LCD are fused to the display frame. Fixing broken glass will be either expensive or very difficult.

It looks like the old assembled desk top PC, with lot of connectors and ICs, each dedicated functional IC's, with lot many juggler connectors,

dvg234 -

Step 6

Why add any thickness of a label over that battery when the battery would never be seen after manufacturing sealed it in? That would be like putting a label over every IC in the phone.

ldunbarl -

does it have ir blaster? i want that nexus 5 comes with ir blaster :( i think it doesnt have ir blaster :(

Licenciado Nexus -

There is no IR blaster, but ridiculously, Kitkat has native support for it. Sometimes I really don't understand Google; Nexus line is supposed to be a dev phone, so why they decided to cut down the IR blaster, when there is software for it, is a big mystery...

Alexander Tatevyan -

The phone comes with a back hoop with a pin to release the SIM card. I stupidly stuck this in the tiny hole at the top of the Nexus 5 that I believe is actually a secondary microphone. I was wondering, using your dismantled phone, if you stick the black pin into the hole can you tell whether it damages the microphone?

Matt Williams -

Could it be possible to change SDIN8DE4‐16G to SDIN8DE4‐32G? Both hardware and software wise, so it is able to boot. Thus getting 32GB storage instead of 16GB.

Uldis Seglins -

I have a similar question.. want to use 64 GB on the 32 model. Is this possible?

Jayendran Ramani -

It appears this chip is physically soldered to the PCB - if you had a machine to remove and replace a BGA from it without damage to other components nearby (such as a Martin Expert 10.6 or similary), you should theoretically have the ability to swap it with any other size memory with the same footprint and input/output pins.

Chris Villareale -

http://hackaday.com/2016/05/10/upgrading... That is the way

Gustavo -

Great guide. I wonder if you have an opinion about the speaker issue and the XDA mod with the 5? One of the features you take for granted in a phone is its sound quality. Everybody oohs and aahs about screen size and processor speed, but a seemingly insignificant and overlooked component, such as a speaker, can ruin a device. Do you think a software update can fix this, or should I consider the XDA mod.

jamieFL -

Where can I get the tools you have used? Can you please provide links?

Thank you.

Jayendran Ramani -

Make sure to press not only the side tabs back in place when putting it back together but the middle also.

I put mine back together and my wireless charging stopped working. once I ran my fingers through the middle of the phone in a pressing motion moving from bottom and working my way up, I heard a click and then the wireless charging started working again.

you will notice if that tab is not in all the way because the back bubbles and if you poke it you see it give a little

Jose Rivas -

Jose Rivas, You're a life saver... i had the problem you mentioned after opening my Nexus5 to do the GPS fix procedure, and after that was unable to use NFC... while searching for a solution, yours came very handy as indeed i had the missing middle click. Just followed your simple instructions and the phone was once again working as it should!! Thanks, mate.

Gemini Gem -

Thanks, I was going crazy after the wireless charging stopped, thought I messed something up. Thanks! Thanks! Thanks! Thanks!Thanks! Thanks!Thanks! Thanks!

YDC -

I feared the NFC chip was broken after I repaired the screen. Your tip restores its function !!! Many thanks!!

Klaas De Smedt -

Thanks for the tip! I have yet to try it out (only have one android in here), but I believe that "middle click" has fixed the NFC on my Nexus 5.

Frederico Flores -

Should have read your comment first! Would have saved me an hour....

Lawrence Lau -

Happened across this by sheer chance, and now I don't have to take my phone back to the repair shop to ask them what they broke! I will tell them about this though :)

Paul Crowley -

I brought my N5 to a cell repair shop to replace a cracked screen and replace the battery. Upon return the Qi wireless charging stopped working. I called back the shop and they didn't know how to fix it and thought something from the battery was lost. THANKS Jose!! I just followed your instructions, heard the click, and charging works again!

Wayne Lin -

As of what I have heard, the battery life on the Nexus is pretty poor.

Is it possible to replace the battery for a longer lasting one?

James Whitehead -

The nexus 5 is an masterpiece but Google and lg have let it and there customers Down

I would love to add another speaker

Maybe a 2900 MHz battery

And a 13mega pix camera

tanny bashir -

Just wonder, how do Google knows if I open up their phone?

halloween88 -

Also, if after disassembly the vibration stops working press/rub down in the middle of the back plate until it snaps into place to get the vibration motor connected again.

jaimevisser -

I just created an account just so I could say thank for stating this. I dropped my phone and the motor was working funny - acted like it was attached to a dying battery where it would vibrate strong at first when typing but the intensity would slowly die as if a battery was draining. I pushed in the middle of the case, heard it pop back into place, and now it works like nothing ever happened!

I have been using this mobile for 4 months and its one of its kind. It is an excellent device, with stunning display, nice graphics and awesome power. And it offers pure Android experience and I even installed the Android L developers version which runs perfectly on my device. The only problem I faced with device is about setting custom ringtone. I found the procedure about how to set ringtone in this link and it worked perfectly, http://www.spinfold.com/set-ringtone-in-...

Naresh Landam -

When prising of the back panel, the adhesive at the bottom was really strong and some of the metal strip on the outside of the speaker module has come away. Any one know what it's connected to? Mic or speaker? (it's the less wiggly one of the two!)

Chris Wellings -

I replaced my Nexus 5 screen, but there is now a hole in the front of the phone where the front facing camera is. If any water gets in this hole then it could do damage.

What have I done wrong when rebuilding it? and how can i fix it? Thanks

Ronel -

BE CAREFUL!

When using this teardown, please note, the author misses listing screws, adhesive, plastic spacers and housings. After several re-teardowns I have finally managed to get all the old pieces (including the buttons) from the old frame/screen to the new.

dark2400 -

Then why not take some pics and update the steps with your discovered oversights?! Telling us "Here There Be Errores" does no one any good. Harumph.

David Spalding -

That's because a teardown is a tour of the hardware, not a how-to guide. If you want a guide, check the main page.

Jeff Suovanen -

Ok!! I dropped my Nexus 5 , which I keep in Tech21 protective case, into the toilet yesterday morning. Yes, I was pinching a loaf and this was not how I wanted to start my day. The phone was under 6 inches of water, and feces, for at least 20 seconds. I used your guide to disassemble, clean with 95% alcohol, and reassemble my Nexus 5. When I plugged the phone to charge the battery light came on for a few seconds and then went dark and this cycle was repeated. I thought I needed a new battery so I ordered a replacement last night. This morning I thought it wise to remove the battery in case there was moisture while waiting for replacement. When I opened the back, removed the 10 screws, took the speaker out, and the cover that covers the battery connector BAMMM! I, immediately, realized the connector to the battery was not connected to the power supply!!!!!!I reattached the connector and made sure it was secure, reassembled the Nexus 5, plugged it in and saw the battery had a 62% charge!!!!! Thanks 4 guide!

While replacing my battery, I accidentally pressed to hard on the male battery connector and broke a part of the female connector on the motherboard. Can this connector on the motherboard be replaced. Thank you Ronnie

rjwill6007 -

Right so my Nexus 5 is from LG Electronics Japan and the screws on the camera cover are like a Y shape but is the same size screws as yours please can someone help me and link the right screwdriver PLEASE!!!

Arkie -

It's called a Trigram, Tri-Wing, or Y-Tip. Not difficult to find online or at your local hardware store. They're often included in interchangeable screwdriver tip assortments.

tjt263 -

I have a problem, I changed the flex wire and the battery and now it doesn't charge. It works perfectly except it doesn't charge. I tried to reassemble again all parts and still the same issue. Do you know what could be ?

When switched on, icon shows it's charging but status says it's not :S

I need to try the wireless charging and see if this fixes the issue, otherwise I am afraid I need to change the phone :(

My nexus 5 vibrates but no display... tried replacing display, no improvement... Help me out with other possible fix or problems leading to it...

Tanzeel Iqbal -

Thank you for sharing this guide!

Last night my nexus 5 drowned.

after drying it from outside i tried to turn it on - it hadn't had the ability to use the touch screen and after i turned it off and on again the screen was dead.

using this guide i open and surprisingly realized that all the inside parts were covered with water - including the sim , the CPU and the battery...

i tear it down completely dry all the parts with a dry towel and left it in rice over the night.

after assembly it in the morning and going over with a cleaning brush (the rice seems to have some white dust) . i said some prayers ,held my fingers and turn it on. it woke up perfectly and there seems to be no problems so far - the screen, the Bluetooth , wifi, GPS, Sim and all the rest are working fine. thanks a lot!

Are they interchangeable or cross-compatible? Why/why not?

Aren't USB standards universal?

I am wondering what component(s) control the display because my phone has been water damaged however the logic board seems to work fine with buzzing when I boot it up and chimes if a unplug the charger but the screen won't even light up. I am convinced the screen is working because I plugged in a different logic board and the screen lights up fine. So my conclusion is that there is something wrong with whatever Controls the display on the logic board. This brings me back to my original question what components on the logic board control the display and is there any way to replace them?
