Edit Step 1 OnePlus One Teardown  ¶ 

  • Before digging our digits into the One, we pause to count up its specs:

    • 5.5" IPS display with a resolution of 1920x1080

    • 13 MP f/2.0 rear-facing camera with dual-LED flash along with a 5 MP front-facing camera

    • Qualcomm Snapdragon 801 processor with 2.5GHz Quad-core CPU

    • 3 GB LPDDR3 1866 MHz RAM

    • 64 GB eMMC 5.0 storage capacity (also available in 16 GB)

    • 802.11b/g/n/ac Wi-Fi, Bluetooth 4.0, USB OTG, GPS/GLONASS, NFC

  • Impressive hardware, to be sure—but this here’s a teardown, and the number One has left us a bit traumatized of late. Here’s hoping the “Plus” stands for “more repairable than phones of yore…"

Edit Step 2  ¶

Edit Step 2  ¶ 

  • Designed by OnePlus and assembled in China, the OnePlus One is identified as model number A0001.

  • The One is powered by a custom version of Android, CyanogenMod 11S, created by Cyanogen, Inc.

  • What's so special about CyanogenMod? It's an open source operating system for smartphones and tablets based on Android. It offers features and options not found in Android versions distributed by mobile vendors.

    • The OnePlus One is the second phone to come preinstalled with CyanogenMod, the first phone being the OPPO N1 CyanogenMod Edition.

  • We're pretty excited to see the One has an open source OS and is completely unlocked, both of which protect the rights of consumers.

Edit Step 3  ¶ 

Image #1

Edit Step 3  ¶ 

  • Compared to the current top-selling smartphone, the iPhone 5s, the One is slightly thicker at 8.9 mm (vs. 7.6 mm) and significantly taller at 152.9 mm (vs. 123.8 mm).

  • While this isn't quite a phablet, reviewers are saying this One's a tad big for single-hand use. Unless, of course, you're the Hulk.

Edit Step 4  ¶ 

Image #1

Edit Step 4  ¶ 

  • Lookie here! What's in this red box?

  • A power adapter and a fancy USB cable with an inside-out connector, has OnePlus finally defeated the USB plug scourge?

  • Oh and a SIM eject tool with keychain caddy. Because, how many times have you wished you had an eject tool hanging off of your keyring?

    • Never? Same here. But it sure looks cool.

  • The nigh invisible SIM slot opens with the touch of said fancy eject tool, and we've breached the perimeter of this monolith.

Edit Step 5  ¶ 

Image #1

Edit Step 5  ¶ 

  • With that, our plastic opening tool is ready to attack!

  • The One presents no obvious point of entry, but since OnePlus will offer interchangeable back plates we decide to start at the back case. We wiggle our way into a seam to see what's what…

  • …and to our delight, the back plate comes off readily—with just a bit of resistance from a few clips around the edge.

  • While interchangeable parts are always a plus for repairability, we don't expect the back to be prone to the same catastrophic failure as the front glass.

Edit Step 6  ¶ 

Image #1

Edit Step 6  ¶ 

  • Baby's got back…case, that is. With the back case free, we see the first glimpse of the embedded rechargeable 3100 mAh LiPo battery.

    • At first glance this One seems to have a heftier, and more accessible, battery than the other One.

  • This back case is a gold-laced antenna party.

    • Spring contacts in several places join three gold antennas plus one NFC sticker antenna to the phone body.

Edit Step 7  ¶ 

Image #1

Edit Step 7  ¶ 

  • We poke at the giant red battery for a bit (reenactment of actual events) until we finally succeed in popping it up with a spudger.

  • Alas! It seems our reach has temporarily exceeded our bite, as the battery cable disappears under a screwed-in panel.

Edit Step 8  ¶ 

Image #1

Edit Step 8  ¶ 

  • No matter—out go the first round of screws, thanks to our Pro Tech Screwdriver Set.

  • But it's not over yet! The One deals us a one-two punch with some hidden screws.

    • We don't take kindly to screws hidden under rubber stoppers around here. And that last screw is sporting a white sticker on its head, now forever maimed by our screwdriver, proving that we've been inside…tampering.

  • The device hasn't proven especially difficult to enter, but small deterrents like hidden and tamper-evident screws never sit well with us.

Edit Step 9  ¶ 

Image #1

Edit Step 9  ¶ 

  • We pull off an interior cover to access the battery connector. If our calculations are correct, the OnePlus One's battery is about to be subtracted.

  • Our spudger performs the necessary arithmetic, and the 3.8 V, 3100 mAh LiPo battery is ours (and yours) to inspect.

  • For those of us who don't read Chinese, this battery sports a maximum charging voltage of 4.35 V, and the following warnings and cautions (paraphrased):

    • Only use with approved chargers

    • Keep ventilated while charging

    • Do not tear down, short circuit, or puncture

Edit Step 10  ¶ 

Image #1

Edit Step 10  ¶ 

  • Removing the motherboard requires disconnecting several connectors.

  • Being as careful as we possibly could be, we use an iFixit Tech Knife (more commonly known as a K-nife) to detach the rocker buttons from the side of the panel assembly.

Edit Step 11  ¶ 

Image #1

Edit Step 11  ¶ 

  • Finally, with all the connectors out of the way, the motherboard is—

  • Drat and double drat! There's one last antenna connector on the back of this motherboard.

    • Luckily, we disconnect it faster than you can add 1+1.

Edit Step 12  ¶ 

Image #1

Edit Step 12  ¶ 

  • Both the front-facing and rear-facing cameras are designed by Sunny Optical Technology.

  • The rear-facing camera is labeled P13N05A, while the front-facing camera is identified as P5V35A.

  • We also encountered camera modules designed by the optimistically-named Sunny Optical Technology in the Project Tango teardown.

  • According to the details on the OnePlus One specifications page, the 13 megapixel rear-facing camera features a Sony Exmor IMX 214 CMOS image sensor.

Edit Step 13  ¶ 

Image #1

Edit Step 13  ¶ 

  • E pluribus unum. Here are the many chips that make up the One:

    • Samsung K3QF7F70DM-QGCF 3 GB LPDDR3 RAM; Qualcomm Snapdragon 801 likely layered beneath

    • Qualcomm WCD9320 Audio Codec

    • AGD2 2402 WX9DR (likely gyroscope)

    • Qualcomm PM8941 and PM8841 Power Management ICs Quick Charge 2.0 capable

    • 8407 CEH 05KTJ

    • B02419

    • P0911 3193

Edit Step 14  ¶ 

Image #1

Edit Step 14  ¶ 

  • We've quickly run out of snappy Latin catchphrases—but chips? Not even close! The backside of the board contains:

    • Toshiba THGBMBG9D8KBAIG eMMC 5.0 64 GB Onboard Storage

    • Skyworks SKY77629-21 Power Amplifier Module

    • Qualcomm WCN3680 802.11ac/FM/BT 4.0 Combo Chip

    • Qualcomm WTR1625L RF Transceiver

    • Skyworks SKY85709 WLAN Front-End Module

    • Synaptics S3508A Touchscreen Controller

Edit Step 15  ¶ 

Image #1

Edit Step 15  ¶ 

  • We shift our focus to the front panel assembly.

  • Six screws (two of them hidden under more rubber plugs) and a flick of a spudger later, we've got the speaker assembly enclosure out.

  • The OnePlus One features a set of Yamaha stereo speakers that connect to the motherboard via spring contacts.

  • In the bottom center of the speaker assembly enclosure, we find a sticker that changes colors when orcs are near. It also acts as a water damage indicator.

Edit Step 16  ¶ 

Image #1

Edit Step 16  ¶ 

  • Peeling up the USB port is easy enough, but it appears to be trapped under a slot in the midframe.

  • Touché! It's not trapped at all! What we thought was a wall was in fact a strip of tape—peel that away, and we're home free.

Edit Step 17  ¶ 

Image #1

Edit Step 17  ¶ 

  • Oh no, this little cable offshoot is threaded under the midframe. We'll never get the daughterboard out—wait just a minute. Never mind.

    • In another exciting plot twist, this mysteriously chipped cable pops right out of its frame crevice.

  • This One has more plot twists than Star Wars has family secrets.

Edit Step 18  ¶ 

Image #1

Edit Step 18  ¶ 

  • The daughterboard is finally freeeeee as a daughterbirrrd, now.

  • This daughterboard is the permanent home of various components, including the vibrator and primary microphone.

  • Along the bottom of the daughterboard are three LEDs for the front panel assembly capacitive buttons. The LEDs fit into the light guides at the base of the display.

Edit Step 19  ¶ 

Image #1

Edit Step 19  ¶ 

Edit Step 20  ¶ 

Image #1

Edit Step 20  ¶ 

  • With the display assembly stripped down to the midframe, it's time to test out a common repair: screen replacement!

  • After some heat and a bit of prying with an opening pick, we separate the display assembly from the midframe.

  • It's not a fun job, but it's certainly easier than another One we opened up on our teardown table.

  • The midframe bears the designation PC+GF, indicating it was made of polycarbonate infused with glass fibers.

Edit Step 21  ¶ 

Image #1

Edit Step 21  ¶ 

  • OnePlus One Repairability Score: 5 out of 10 (10 is easiest to repair).

    • No proprietary screws and only one screw head type decreases cost of tools for repairs.

    • Fairly modular components will allow for less expensive replacement parts.

    • Slight adhesive used on the battery and several cables.

    • With its connector trapped under a plastic panel and several screws, the battery is more of a chore to replace than necessary.

    • The LCD and digitizer glass are fused together and must be replaced as a single part, and they require heat to remove from the midframe.

Hey guys, nice teardown. I'm guessing you probably already gave out your spare invites to your fellow workmates or friends but if you haven't I'd be eternally grateful for one.

Guy, · Reply

Are you kidding me with this?


Haha some ppl really can't hold there s**t together

yossi Grosskopf,

I bought 2 OPOs (sold one to a client, kept the other), both over a month ago, and have not received any invites. The invites I bought were $ 23.00 and $ 9.00, respectively, but now they seem to be in VERY short supply, and are going for bigger bucks. Not sure what's up with that!

PJ Blank,

Thank you. I was really waiting for this. OnePlus said they made the battery unremoveable to make the phone thinner, because they don't have to cover up the cables underneath.

That being said, do you think it's possible we will see a battery hack kit appearing on eBay? One that has a battery connector extender that extends to connector pins in the battery compartment and then a matching battery that can just be popped out?

Arend Hamming, · Reply

Luckily, the OPO seems to have commendably long battery life, and many drugstores and convenience stores sell lithium packs with USB connectors for $ 10-$20 or so that just plug into any smartphone for extra power. I know, maybe unwieldy and not pretty, but functional!

PJ Blank,

How many wifi antenna's are there in the OnePlus One?

Rick Reeves, · Reply

What's interesting is that that those Yamaha speakers have been called JBLs in quite a few other articles (like this one: Do you think that OP is hyping the product inaccurately, that different OPOs carry different speakers, or that well-meaning collaborators are reporting specs based on deals that they're not aware never went through?

can anyone tell me where to buy a new screen?

aliexpress, for one, and ebay, for two.

PJ Blank,

can anyone tell me where to buy a new screen? mine cracked.

cheis, · Reply

aliexpress for $118. Came in a week and worked great!

Dev Mikel,

where can i buy the the sim tray from ???? looks like i have damaged mine

mjaffar, · Reply

Just use a thin Scotch tape to hold the SIM into the broken frame. You did not describe the breakage so I can assume the frame is cracked. Also consider trying some superglue.


Hmmm. I added what I believed to be important edits to this teardown, such as describing the two types of screws in the phone, mentioning some additional care when disassembling, removing a screw not mentioned in Step 10, and such. This appears to have been completely disregarded, and there is no longer a link to view unverified comments as of this time (and no notice to me, as if I was trying to do something malicious). I urge all who disassemble the OPO to be extra-wary of a few "gotchas". Guess I'll add them as comments to the steps instead.

Good luck.

Why does this get a lower rating than the Nexus 6? The nexus got a 7 and this got a 5.

In the Nexus 6 guide the back cover was glued on, this isn't the case with the OPO

In the Nexus 6 there were something like 22 screws holding the back on, theres far few with the OPO

With the Nexus 6 you complained that many parts weren't detachable like the MicroUSB port, in this phone many more components are attached via removable ribbon cables.

Oscar VL, · Reply

After following the teardown to replace broken screen, phone can't connect to mobile networks/carriers. Which antenna/connector should I double check?


no way, · Reply

My display has come unstuck. how can I paste it? need to completely disassemble? and what glue I need to use ...

Arshik27, · Reply

Looks like your fine work has been leeched here (and the text mangled in places):

Jon Green, · Reply

Hello just replaced the display but unfortunately the mic and speaker do not work... Any Idears what to check?

sieratangoromeo, · Reply

Hello, I'm looking to buy the lcd+digitizer+midframe assembly for the supposed sake of convenience. What would be the differences compared to what's shown in this specific teardown? Would it require a lot less steps or would I still have to go through the steps shown here? Thank you!

Dice Craps, · Reply

Be sure to remove the SIM card tray before removing the back plate!

Andrew, · Reply

So, with the NFC antenna being part of the cover instead of the body/battery, is it safe to assume that a ferrous metal plate (used with a magnetic dock) wouldn't interfere with NFC use?

Sergio Ferreira, · Reply

Went ahead and got one of the magnet docks. The metal plate behind the One's back cover (between the cover and the battery) does NOT interfere with NFC, or any other radio that I've tested.

Sergio Ferreira,

Do we know which NFC chipset the 1+1 is using? I've heard different sources cite an NXP PN65T or a Broadcom. It matters a great deal as far as tag/card compatibility goes!

Libra Sun, · Reply

NXP. Source is this Chinese OnePlus One teardown:


Direct picture link with the NFC chip from NXP:


Is there anyone that know which one of the antennas that are for wifi and so on?

rbrostrom, · Reply

Note small screw at bottom left ("little black dot" on lower left of mobo in main picture for this step). It must be removed to take out the mobo. This is one of 3 screws of a different size in the phone. The other two are under the little plugs in the speaker assembly, Step 15.

Also, note connector to the left of the rear-facing camera at top of mobo in this step. It has to be disconnected just like the connectors at bottom of mobo.

PJ Blank, · Reply

Thanks a lot for the guide, my phone has been diagnosed with water damage and had to change motherboard and small board, which I thought they did just that. But turns out my screen might have been switched/changed as well? Since my screen protector isn't here anymore compare to before I sent it for repair it's still attached.

My question is: Does the screen has to go too if the motherboard has been replaced? Or have I simply been scammed? Also, is it common that your internal memory will be wiped out?

Comments will be very much appreciated, thank you.

Krys, · Reply

Replacing the motherboard will definitely wipe out the on-board storage. I can't see any reason why the display would need to be replaced, unless it also had water damage.

Jeff Suovanen,

You couldn't identify all of those chips? very fishy...

Bob, · Reply

You forgot to mention the stereo speakers is by Yamaha.

Google, · Reply

you forgot to read step 15


Isn't it "the stereo speakers AM by Yamaha"?

PJ Blank,

is it really stereo or just 2 mono speakers?

Craig Ferguson, · Reply

2 speakers but they are not wired "stereo". Both carry the same program material, so they are mono.

PJ Blank,

The two screws under the little plugs are of the 2nd type used in this phone; the first of this type is in Step 10 (see my comment for that step). Total of 3 screws of this 2nd type. The 1st type (the rest of the screws) are, AFAIK, all the same.

PJ Blank, · Reply

Can you please tell the specific of the original oneplus one usb cable?

Marco Salvioni, · Reply

This could be a magnetic sensor.

Tom Chai, · Reply

yes, this is magnetic senzor for flip cover ;-)


This daughterboard is home to... the vibrator. What a naughty daughter.

Stefan Constantin Dumitrache, · Reply

Is the vibration motor soldered on the daughterboard? Is it detachable?

ionpan, · Reply

Don't forget the antenna connector at top of the "right wing" (viewed from rear of phone with daughterboard on bottom) of the daughterboard. As with the mobo antenna connector, it pops off with a little prodding.

PJ Blank, · Reply

Where can i get that part? I looked entire ebay.

bostjan, · Reply

Note the orientation of the earpiece speaker BEFORE removing it from the frame!

PJ Blank, · Reply

Just noticed that earpiece speaker is "keyed".. small tab on one side, larger on the other. Probably difficult to install it backwards.

PJ Blank, · Reply

That white rectangle where the headphone jack was is a liquid damage indicator. It also appears that they left a hole in the headphone jack purely to allow water into the main circuitry via that LDI...

Yoda, · Reply

And it allows it to lift the backcover with the headphone jack.

Oneplus shows this technique in their videos, e.g. the one showing how to swap the original cover to use their bamboo cover.

Wozniak Peter,

The earpiece on the picture is upside down !

Pierrick FRIZE, · Reply

Yes. The photo shows the speaker upside-down. But its not possible to mount it that way.

I think it is IMPORTANT to mention the following:

The speaker is stuck with some adhesive.

By trying to lift it up it is very easy to destroy this fragile component.

The problem is, the metal frame of the speaker is stuck by an adhesive sticker. And by lifting the black plastic, the two parts break up! If your are unlucky the super thin copper wire breaks and the speaker is dead.

So please. Lift the speaker underneath the metal frame which is hardly visible.

And also take care not to perforate the membrane.

So it is necessary to be very gently or to buy a new speaker

Wozniak Peter, · Reply

Are you sure there's no magnesium midframe? The last picture of step 20 looks like some kind of metal midframe

Eric Shen, · Reply

Can you recommend a certain type of glue?

I need to buy some for the reassembly.

Daniel Lottes, · Reply

Careful! Thin black plastic strip around screen / digitizer assembly is PART OF MIDFRAME! Mine was severely damaged while removing the broken screen. Came out in pieces. Had to order new midframe.

PJ Blank, · Reply

so, I have managed to get the display free. I am now waiting for the delivery of the new display. can I use the old glue again or should I take new ? what kind of glue ?

Dom, · Reply

Just got the new midframe. Expect to be back here to say how it went.

PJ Blank, · Reply

Can anyone suggest a glue to use for reassembling the screen?

Rick Reeves, · Reply

PJ Blank how did it go? I bought a new frame also and it came with adhesive that's shaped like the phone but it does not have the cut out for the screen's flex cable however it has some cut outs in it I'm just not sure what to do

Kevin Watson, · Reply

someone could tell is possible separate the scanner glass lcd?

Dj Thiago Na Balada, · Reply

New display from aliexpress does NOT have copper strips!!

Will it work?

PopeMike, · Reply

As anyone ever saw a video or knows how to "de-fuse" the Digitizer from the LCD? I found a store that only sells the glass/digitizer for 50€ and was really tempted to buy it (instead of the whole piece for 100€). In this website they say that they will send a video explaining how to do it but apart from a video I saw on XDA about the same procedure on a Galaxy S2 I never found out anything similar for the OPO.

Pedro Miranda, · Reply

So the 5 out of 10 is just grab the eyes? Somehow a much-more-difficult-to-fix iphone 5 got a 7 out of 10. Random scores?

Sli Anand, · Reply

i need to replace the lcd and the digitizer.. Can you assist me with the steps tha follow after removing the back cover.. and removing the visible screws is it possible to directlyu dettach the display?

and once i remove my display how do i attach a new one?

Help would be highly appreciated!

Amit Shah, · Reply

From my own teardown of the phone (and waiting on replacement display now), it looks like you need to do the complete teardown to change the display. My display was shattered; I used Scotch tape on the screen front to keep glass shards from getting everywhere. I used a heat gun to separate the display (and digitizer, which are one unit) from the frame. Will probably come back here to let you know how it goes.

PJ Blank,

where i can buy daughterboard with microphone ???

my microphone dead and the phone is useless now ...
