Motorola Moto X Teardown

Teardown

Teardowns provide a look inside a device and should not be used as disassembly instructions.

What does $12.5 billion dollars buy you nowadays? In Google's case, it buys Motorola, Inc. and all of its designs and patents. Is it what we would have spent the money on? Probably not, but the result of the acquisition is Motorola's first smartphone, designed and assembled in the United States—the Moto X.

Edit Step 1 Motorola Moto X Teardown  ¶ 

  • The love child of Motorola and Google is here, and we are dying to crack open the little Motoroogle.

  • Technical Specifications:

    • Dual-core 1.7 GHz Qualcomm Snapdragon S4 Pro processor

    • 2 GB RAM

    • 4.7-inch 1280x720 pixels AMOLED display

    • 16 or 32 GB internal storage

    • Qualcomm Adreno 320 GPU

    • 10 MP rear-facing camera

Edit Step 2  ¶

Edit Step 2  ¶ 

  • The top of the Moto X houses the centered headphone jack. We haven't seen this placement on too many recent smartphones.

  • Does it make more sense than a headphone jack on the bottom of a phone? Only time will tell…(but yes, it probably makes more sense).

  • Since we tend to have a lot of devices laying around, we might as well do some comparisons! The Moto X is certainly not small, but it is a bit smaller than the S4, and we are fans of the contoured back.

  • This is the first and only smartphone that's "Designed & Assembled in the USA," to our knowledge.

Edit Step 3  ¶

Edit Step 3  ¶ 

  • Our Moto X has a small defect next to the SIM card tray. Hmmmm...

    • Hopefully this sort of flaw will be limited to the first run phones, and my custom teal model will be made with a little more care.

  • Using the fancy SIM eject tool provided by Motoroogle, we remove the SIM card tray from the side of the device.

  • We're interested to see the internal layout of this device, with so many components lined up along the center.

Edit Step 4  ¶

Edit Step 4  ¶ 

  • Snap snap SNAP!

    • The melodious sound of easy teardown access fills our ears as we release clips holding the rear panel in place.

  • What is this? Google! Motorola! How could you do this to us?

    • To our dismay, the unexpectedly flexible rear panel, though clipped to the device, is also adhered. Time to bring in some reinforcements.

Edit Step 5  ¶

Edit Step 5  ¶ 

  • Designed to penetrate the impenetrable, to de-here the adhered, to unfasten the hard-fastened, the iOpener has yet to meet gobs of adhesive it couldn't handle.

    • OEMs please take note, this is not a challenge…

  • Whilst removing the rear panel, we get our first glimpse at the NFC antenna.

Edit Step 6  ¶ 

Image #1

Edit Step 6  ¶ 

  • Even after defeating Big Blue, the rear panel still does not yield.

  • We release the ZIF connector of a big ol' rear-case-mounted flash assembly, and after 6 full steps, we are finally into the device.

    • Our guess is that the adhesive pad was added to make the phone feel more solid than one purely secured with clips. The pad also keeps the flash firmly in place, and may act as as padding to protect internal components.

  • Our "Woven Black" case has a nice weave. While it's probably not actual kevlar fibers, the molding makes for a nice view — you can see right through it!

Edit Step 7  ¶

Edit Step 7  ¶ 

  • The pattern of these NFC coils triggers some powerful nostalgia.

    • The good ol' days of slot car bliss. Back when toy cars were as easy to drive as Autopia racers. Hold down a button. Watch them race around for hours and hours. Ahh…

  • Snap back to reality, there go the volume and sleep buttons, all on one handy cable.

Edit Step 8  ¶ 

Image #1

Edit Step 8  ¶ 

  • "We'll just wrestle this battery off here…Or not."

    • Time to chase down the end of the NFC antenna ribbon cable.

  • We interrogate the antenna assembly about the whereabouts of the cable's end. Nothing like a 54 Bit Driver Kit to encourage stubborn hardware.

  • Eureka! Adios, battery!

Edit Step 9  ¶ 

Image #1

Edit Step 9  ¶ 

  • Motorola claims the Moto X battery can power through an amazing 24 hours of "mixed usage."

  • How does the Moto X accomplish such a feat with a 3.8 volt, 2200 mAh Lithium ion battery? The secret is in the X8 Mobile Computing System.

  • The Motorola X8 Mobile Computing System is comprised of a Qualcomm Snapdragon S4Pro family processor, a natural language processor and a contextual computing processor.

  • Motorola developed a custom system architecture, which, when coupled with eight processor cores, allows for the delegation of processing power:

    • 4 graphics processor cores for "stunning clarity"

    • 2 application processor cores for "swift action"

    • 2 low-power cores—"awaiting your next command"

Edit Step 10  ¶ 

Image #1

Edit Step 10  ¶ 

  • Out comes the upper midframe panel, housing the speaker, headphone jack, more antennas, and pressure contacts.

    • Yay, pressure contacts! We like spring pressure contacts because they don't require any work to disconnect.

  • This is possibly the most modular headphone jack we've ever seen. It pops right out of the upper midframe panel, spring contacts and all.

Edit Step 11  ¶ 

Image #1

Edit Step 11  ¶ 

  • A spudger helps us unclip a small microphone board from the earpiece speaker.

  • The microphone assembly clings (like a baby sloth) to the earpiece speaker to maintain a solid connection with the spring contacts below.

  • Naturally, we love design innovation. We can tell that a considerable amount of effort went in to the internal design of this device; the number of clips and contacts we've found so far is a great testament to that.

Edit Step 12  ¶ 

Image #1

Edit Step 12  ¶ 

  • After selecting our favorite pair of precision tweezers, we remove the 2 MP front-facing camera from the Moto X.

  • The front-facing camera is labeled as 84016172 REV A 0054067 01017429 142-3.

Edit Step 13  ¶

Edit Step 13  ¶ 

  • The motherboard is ours for the taking, and take we will. Let's just hope there's a little more excitement on the other side of the board.

  • Alas, the streets of this circuit city are looking a little bare. We're going to guess there's a lot more fun to be found under the myriad EMI shields. Only one way to find out…

Edit Step 14  ¶ 

Image #1

Edit Step 14  ¶ 

  • Before we can fully examine the motherboard, though, we must remove the 10 megapixel rear-facing camera.

  • 10 MP is 25% more pixels than the camera in the iPhone 5, but isn't quite on the Lumia 1020's level, though we can hardly fault it for that.

Edit Step 15  ¶ 

Image #1

Edit Step 15  ¶ 

  • Notable ICs on the motherboard:

    • Toshiba THGBMAG7A2JBAIR 16 GB eMMC NAND Flash

    • SK Hynix H9TKNNNBPDAR RAM (we assume that the Snapdragon S4 Pro is also layered under this IC)

    • Qualcomm PM8921 Power Management IC

    • Texas Instruments TMS320C55 Digital Signal Processor

    • NXP 44701 NFC Chip

    • Skyworks 77619-12 Multiband Multimode Power Amplifier Module for Quad-Band GSM / EDGE and Penta-Band (Bands I, II, IV, V, VIII) WCDMA/ HSDPA/ HSUPA/ HSPA+/ LTE

    • Texas Instruments MSP430 F5259 Mixed Signal Microcontroller

Edit Step 16  ¶ 

Image #1

Edit Step 16  ¶ 

  • Additional ICs:

    • Qualcomm WCD9310 Audio Codec

    • Qualcomm WCN3680 802.11ac Combo Wi-Fi/Bluetooth/FM

    • NXP TFA9890 High Efficiency Class-D Audio Amplifier

    • Skyworks 77737 SkyHi™ Power Amplifier Module for LTE Bands 12/17 (698-716 MHz)

    • EPCOS 7959 Wireless LAN/Bluetooth Filters (IF)

    • Qualcomm WTR16505L LTE/HSPA+/CDMA2K/TDSCDMA/EDGE/GPS Transceiver

Edit Step 17  ¶ 

Image #1

Edit Step 17  ¶ 

  • Teardown update: We got ahold of a Verizon version of the Moto-X and played a little game of 'spot the difference' with the motherboard:

    • SanDisk SDIN8DE2-16G 16 GB NAND Flash replaces the Toshiba

    • Samsung K3PE0E00QM-CGC2 2 GB LPDDR2 RAM instead of SK Hynix

    • The Verizon model adds another Qualcomm modem, the WTR1605 (in addition to the WTR1606L, possibly used solely for LTE support on this model)

Edit Step 18  ¶ 

Image #1

Edit Step 18  ¶ 

  • The back of the motherboard may look bare, but upon closer inspection we found two microphones:

    • Wolfson Microelectronics WM7121 Top Port Analogue Silicon Microphone

    • Wolfson Microelectronics WM7132 Bottom Port Analogue Silicon Microphone

  • Motoroogle again shows off its novelty; the X's vibrator motor is soldered right to the motherboard. The wonders never cease.

  • Like any good warrior, we hold onto the ears EMI shields of our enemies.

Edit Step 19  ¶

Edit Step 19  ¶ 

  • The mobo is no mo', and we get to examine the backside of the display assembly, which is adorned by some nice comfy foam.

  • One thing about this device is certain: the design choices are nothing if not unique. The midframe is held in place by pins protruding from the edges of the display assembly bezel.

Edit Step 21  ¶

Edit Step 21  ¶ 

  • Motorola Moto X Repairability Score: 7 out of 10 (10 is easiest to repair)

  • Pressure contacts and cable connectors make the modular components (cameras, buttons, headphone jack and speakers) easy to replace.

  • The Moto X uses a single kind of screw, although it's a fairly uncommon size (T3).

  • The taped-in battery is less accessible than we'd like, but at least it's near the top of the stack once you get the rear cover off (as opposed to the HTC One).

  • The digitizer is fused to the display, increasing repair costs for a cracked screen. But the display midframe can be separated, potentially lowering the cost of the replacement part.

  • Sticky adhesive on the back cover is annoying and will slow opening the phone.

what is the chip of GPS?

Confirmed, the WTR1605L is just to the right of the Toshiba memory, above the NXP NFC and TI MCU devices.

chipguyic,

Looks like Avago has LTE band 7 covered with the A5007 device. Just above the SKY77737 and to the left of the EPCOS WLAN/BT filters

chipguyic,

The GPS is likely integrated with the RF transceiver, but this device was not called out on the logic board. It is likely the WTR1605 part, given the other QCOM silicon contained within.

I saw the comment that no Samsung components but wondered if the display is made by them? I see SDM on the part numbers.

Is there a touch controller IC? If so, who makes it?

Impressive teardown. Keep up the good work.

To your question "Does it make more sense than a headphone jack on the bottom of a phone? Only time will tell…(but yes, it probably makes more sense)." I strongly agree; I would suggest that it is much better to have the phone in your pocket with the earbud wire coming out the top than for the connector/wire to be bent/stressed down at the bottom of your pocket.

Thanks, but it not include as I can replace physical damage glass.

Could you extend this guide?

maximyual, · Reply

can somebody tell me how to remove the emi shields that are soldered to the board?

2dspectre, · Reply

Does anyone know where I can find the plastic/rubber gasket piece that sits over the proximity sensor. I've had the careless misfortune of losing not 1 but 2 of these during past services on this model, and have discovered them to be vital in the operation of the proximity sensor and thus the phone itself.

T3 screws on the upper frame are stripped, any suggestion to remove them?

Really cool! Nice gadget to add Moto X's storage- a tiny Meenova MicroSD reader: http://goo.gl/2iJ6gf

*note* If you don't use a wide prying tool (Like the one in the picture), you will likely crack the outside edge of the back cover.

Jason Ross, · Reply

Fake rubbery carbon back cover is harder to remove than the stiffer pink back cover variant:

It uses two layers of glue in between a silicon buffer, the glue pad on the outer side sticks way better to the rubber than the layer that adheres to the nfc antenna/battery. Danger here is the connecting element for the camera flash being sandwiched here also,

is more fragile during the removal (due to bendiness) at weak points like the volume buttons and the first points near the SIM slot. Make sure the glue got warm enough.

Adrian Koch, · Reply

Obviously the phone you tore down was saturated with glue... but I don't think they all are. I've torn down 5-6 of these devices and not run into the glue yet (the back just pops off super clean and easy). The phones I attacked were couple of custom colored ones from the online store and a handful of "developer edition phones". Maybe the glue is just on the stock / mass produced variant?

I had a first run version and it had lots of adhesive just like their teardown model.

Jason Ross,

I miss my slot cars! Kids today have no idea how cool it was to start out with a basic one and step up to customizing everything, from motor to gear ratio, and to get crazy with a custom painted molded chassis.

Those were the days. Tiger milk!

How do you guys remove the EMI shield so neatly?

alisio, · Reply

It's interesting that the vibrator motor is rigidly attached to the PCB and is next to the camera. Many Moto X's develop a problem that makes the camera stop working over time. Is there a connection? (or should I say, a loose connection?)

waldo, · Reply

The front glass is insert molded with plastic

Neo, · Reply

Don't buy the replacement glass only from ebay, buy the glass + frame. You will see that the glass only has a "lip" for the plastic mold to mold over, which is something most of us cannot do. Also, beware that the glass over the front camera, make sure it is NOT tinted before install... The one I got has "tint" over it, which is actually meant for the proximity sensor (IR)

xusdf, · Reply

Glass+frame is the way to go if just the Glass is broken, but LCD and touch still work.

You also don't need to disassemble it completely. Only open the bottom two torx screws, then heat up the glass and carefully remove the glass parts from the panel and frame. Pry off the the old frame but don't loose the bolts, you'll need them. Ebay frames+glass come without bolts.
