Bu teardown bir tamir kılavuzu değildir. Google Pixel 4 XL cihazınızı onarmak için, servis kılavuzumuzu kullanın.

  1. Normally we're all about high resolution, but this is shaping up to be the most Pixellated teardown ever. Check out the specs on our teardown unit: 6.3" OLED display with QHD+ 3040 x 1440 resolution (537 ppi) and variable refresh rate up to 90 Hz Octa-core 64-bit Qualcomm Snapdragon 855 processor, paired with 6 GB of LPDDR4X RAM

    • 6.3" OLED display with QHD+ 3040 x 1440 resolution (537 ppi) and variable refresh rate up to 90 Hz

    • Octa-core 64-bit Qualcomm Snapdragon 855 processor, paired with 6 GB of LPDDR4X RAM

    • Dual rear-facing camera with one 12.2 MP ƒ/1.7 wide-angle module, and one 16 MP ƒ/2.4 telephoto module; single 8 MP ƒ/2.0 wide-angle selfie cam

    • 64 GB of onboard storage (128 GB optional)

    • IP68 ingress protection rating

    • Android 10 mobile OS

    • Google, we'll see your radar and raise you some X-rays. Our esteemed colleagues at Creative Electron provide an early look at this Pixel's internals—and it looks like a completely different layout from Pixels 2 and 3.

  2. Lining up our new Oh So Orange Pixel 4 XL against last year's Clearly White 3 XL invites a few observations: Notable changes include the loss of (one of) the front-facing speaker grilles and the fingerprint sensor of yesteryear. The new speaker setup still counts as stereo sound, but the lower speaker fires out the bottom (like an iPhone) instead of at your face. The SIM tray also packed up and moved, likely to accommodate aforementioned speaker placement.

    • The SIM tray also packed up and moved, likely to accommodate aforementioned speaker placement.

    • The Pixel 3's notch has evolved into a whole bezel! While everyone else in the industry works furiously to eliminate notches and bezels, Google's approach seems a little more laid-back.

    • At least they put the space to good use: inside they've crammed infrared facial recognition hardware, a wide-angle front-facing camera, and a cool new radar thing.

    • In case you're looking for a more Apples-to-Oranges comparison, here you go.

  3. If this phone came with repair instructions, we're sure the first step would say "Apply heat to the surface marked in orange." So, we do just that. The adhesive underneath is mercifully thin, but strong nonetheless. At this point, we'll take anything over that thick goopy gunk from last year. With no more fingerprint sensor, we hoped to cut in without encountering any flex cable booby traps—but alas, a new even shorter cable connects the miscellany on the rear camera bump: flash, microphone, and the spectral + flicker sensor.

    • Fortunately, the wireless charging coil & NFC coil, newly adhered to the back panel via a sheet of adhesive, use repair-friendly spring contacts.

    • Unfortunately that means that back cover adhesive needs to be strong. You don't want loose contacts when it comes to charging circuitry.

    • We might not need all 112 bits to dismantle this Pixel, but we're glad we brought our Manta Driver Kit along for this one! We fish out a Torx 3 bit and start twirling away screws.

    • Normally, we love pulling out stretch-release adhesives—they're far more repair-friendly than messy tapes and glues. But you gotta pull at a shallow angle to avoid snagging and breaking them, and good luck doing that here. Like in the 3 XL, you'll likely need to remove the motherboard for adequate clearance, which requires many additional steps.

    • With the benefit of experience, we carefully complete the battery extraction using some IPA and gentle prying.

    • Underneath, a small but serious landmine lies in wait for would-be repairers: a delicate Active Edge flex cable, just begging to be accidentally sliced during battery extraction.

    • The battery itself is a 14.24 Wh cell (3700 mAh at 3.85 V). That's up from last year's 13.2 Wh, and nipping at the heels of the thumping big batteries in the iPhone 11 Pro Max (15.04 Wh) and Galaxy Note10+ (16.56 Wh).

    Hello, I was just wondering if you had any data on the volume/dimensions of the battery? I am doing a research project about power storage in modern phones. Thank you.

  4. We have to dispose of quite a few brackets and shields on our way to the motherboard, but it's all worth it for these chips: 6 GB of Micron LPDDR4X RAM layered over the Qualcomm Snapdragon 855 SK hynix H28U72301CMR 64 GB Universal Flash Storage

    • SK hynix H28U72301CMR 64 GB Universal Flash Storage

    • Samsung K4U4E3S4AF-HGCJ mystery RAM, with a big "P" on it—best guess, this is dedicated RAM for the new Pixel Neural Core chip, likely hiding directly underneath

    • Pixel H1C2M3 Titan M security chip

    • Knowles 8508A quad-core audio processor, no doubt to help with the new live caption and transcription features.

    • Murata SS9709025

    • Avago AFEM-9106 (likely a front-end module)

    If I were to make an educated guess, I would say that the mystery RAM is 4 Gb (0.5 GB) of LPDDR4x RAM :)

  5. Side B of this record features: Skyworks Sky5-8212-11 front-end module
    • Side B of this record features:

    • Skyworks Sky5-8212-11 front-end module

    • Qualcomm QET5100 envelope tracker

    • Qualcomm PM8150 and PM8150A PMICs

    • STMicroelectronics ST54J NFC controller

    • Maxim MAX77826 companion PMIC

    • XSPT6 SMC85201 Z

    • 35L36CWZ BOCW1909

    Thanks! We will update the chip ID with this.

    Arthur Shi -

    Why is there a front end module for 5G if 5G is not being used in this phone…?

    Sam Black - Yanıt

    Sorry! The module is actually more general-purpose than stated. I’ll adjust the text.

    Arthur Shi -

  6. Teardown update: We removed that mystery Samsung RAM chip referenced above, and found a new IC underneath. This could be some custom Google silicon, but the markings are unfamiliar to us.
    • Teardown update: We removed that mystery Samsung RAM chip referenced above, and found a new IC underneath. This could be some custom Google silicon, but the markings are unfamiliar to us.

    • We'll work on tracking down its origin. Meantime, if you know more than we do, give us a shout in the comments!

    • The chip package is marked:

    • S4LV001A01 NGWF6YY5 1930

  7. The dual rear cameras come out, joined at the hip. They are nicely labeled "wide" and "tele" on the flex cables. Thanks, Google. The 16 MP telephoto sensor might sound superior to the 12.2 MP when counting megapixels alone,  but the wide sensor should handily win most image quality contests with its wider aperture and larger 1.4-μm pixel width. Next out: the front-facing sensors, including the 8 MP front-facing camera, and the  Face ID face unlock hardware. (The ambient light sensor stays stuck to the display for now.)

    • The biometric hardware consists of two well-separated Near Infrared (NIR) cameras, a NIR flood emitter, and a NIR dot projector.

    • But where's that Soli radar chip? Okay Google, where did you hide it?

  8. Next we pry out this hunk of ... stuff, which turns out to be an earpiece speaker, mic, ambient light sensor, and the Soli chip, for interpreting your gestures using the power of radar. Google calls this implementation of its in-house Project Soli Motion Sense. Although radar technology has been in use for a long time and seems simple enough on paper, we're at a loss as to how Google stuffed the entire system into a tiny featureless rectangle with no moving parts.

    • Although radar technology has been in use for a long time and seems simple enough on paper, we're at a loss as to how Google stuffed the entire system into a tiny featureless rectangle with no moving parts.

    • Motion Sense works by emitting precisely tuned waves of electromagnetic energy. When those waves bounce off of something (like your hand), some of them reflect back to the antenna.

    • The Soli chip then studies the reflected waves and analyzes their time delay, frequency shift, and other data to learn the characteristics of the object that reflected them—how big it is, how fast it's moving, in which direction, etc.

    • Soli then runs that data against its known gesture database to determine what action, if any, needs to be performed in the OS.

    • TL;DR: magic rectangle knows your every move.

  9. Google gifted this Pixel with a supersmooth (sometimes)  90 Hz screen—a rarity thus far, even amongst the flagship-iest of smartphones. Google also made sure nobody could take it from the Pixel without a struggle. Strong perimeter adhesive + screen layers going literally to the edge + giant duct-tape-like adhesive pad = screen does not want to come out intact. In theory there's no reason to do this—only broken screens need be removed this way. But this is not a fun process for replacing an (all too common) broken screen.

    • At least in this case, the result is interesting: this display is manufactured by Samsung! This comes as something of a surprise, given that Samsung has not yet put a 90 Hz display even in its own smartphones.

    • On board, we also find a somewhat unexpected chip package from STMicro, likely a capacitive touchscreen controller.

    Do you have the chip number for the ST one

    Daniel Milburn - Yanıt

    It’s FJABH 07D924 83C0K. You can double check here.

    Arthur Shi -

    Is the display optically bonded like the ones in iPhones?

    gurupanguji - Yanıt

    Yes. The OLED panel is bonded to the glass. You won’t be able to replace the front glass only without specialty tools…especially because this is an OLED and not an LCD.

    Arthur Shi -

    If anyone is here looking for tips on replacing the screen I just did my first P4XL.

    The front glass glue is not as strong as I was expecting but they are not kidding when they say you won't be able to get it in one piece.

    You can do this repair without removing the motherboard, but it does need to be loosened enough to move up a little to allow the board to move up. This basically means taking out the retaining screws and ribbon cables and nudging the board up over so slightly to slide the new connector in.

  10. While its construction remains (disappointingly) familiar repair-wise, we did find quite a few treats in this pumpkin:
    • While its construction remains (disappointingly) familiar repair-wise, we did find quite a few treats in this pumpkin:

    • The Motion Sense-managing Soli chip lives next to the speaker at the top of the phone, and is incredibly tiny, considering its functionality.

    • Our best guess is that the Pixel Neural core is layered under some dedicated Samsung RAM, meaning it must be doing some heavy lifting.

    • We also found a new Knowles audio processor chip, which is likely a major player in all of the new on-device speech recognition features.

    • Samsung made the 90 Hz-capable display—looks like Pixel beat the Galaxy phones to the punch on this feature.

    • But back to that familiar feeling—what will this phone score?

  11. Son Düşünceler
    • All screws are standard T3 Torx fasteners.
    • The stretch-release adhesive securing the battery may not be foolproof, but its inclusion is repair-friendly.
    • Waterproofing measures complicate repairs, but hopefully make them less common.
    • Display repairs continue to be difficult, requiring complete disassembly of the phone.
    • All repairs require access through the stubbornly-glued back panel.
    • Glass on the front and back doubles potential drop damage.

Any indication of why WiFi 6 is not supported despite being supported by the CPU? Is it missing a chipsets or antenna configuration that other WiFi 6 compatible phones have (that use the same Snapdragon 855 processor)?

Mikecant - Yanıt

The Murata WIFI chip in Step 5 does not support WIFI 6.

Dinan Blueje -

Ugly, not repairable, 2016-like specifications on a 2019 smartphone? Will NEVER buy for $1000

How does the FCC even allow this?

Dinan Blueje - Yanıt

Lol - chill out buddy. And why would the FCC have anything to do with allowing a product to be released / priced / etc.? Unless you’re referring to the use of the Soli radar bands…

Matt J -

Remember all those phones from 2016 with 90 Hz refresh rates, radar, face unlock, e-sim.

Jon Xuereb -

So does the Pixel Neural Core chip, in fact, lie directly below the Samsung K4U4E3S4AF-HGCJ mystery RAM in a POP config?

Chris Villareale - Yanıt

If it is indeed the Neural Core, then yes! It would be a POP config.

Arthur Shi -

Two and a half years after the pixel 1 release, you made a wallpaper of the guts… any chance we'll get the pixel 4 and pixel 4 xl guts wallpaper before 2021?

mark - Yanıt

Can you say which GPS chip was installed?

Sascha Hochstuhl - Yanıt

You didn’t hit the “hyperspectral sensor” that’s glued to the top of the camera bump!

There’s been almost no detail revealed about that feature, save for passing keynote comments. Ya’ll still have a chance to update this teardown with a breaking analysis of what that might actually mean. (Nevertheless, solid post. Thanks!)

Dave - Yanıt

Here is a shot of the sensor. It is tiny (half the size of a grain of rice)! It looks like there is an imaging sensor covered by a grid of tuned filters. It’s able to detect specific frequency light through those filters.

While there are many uses for spectral imaging, Google introduced this tech in the Pixel 3 as a means to detect TV/monitor screen flicker so that when you record video, it can adjust to reduce flicker/banding. I think it’s still used for that purpose in the Pixel 4 XL.

Arthur Shi -

Was going to consider upgrading to Pixel 4 from my Galaxy S5, but answer is a definite no. Lack of RAM. 6 GB is no better than my S5 from 5 years ago. Lack of a reasonable battery replacement. Incredibly small battery for 2019. Again, my S5 battery is larger, plus it can be replaced by me in 2 minutes. No headphone jack. No 4K / 60 frame video. Although I can live without this. No Wi-Fi 6. No 5G. Looks like I will be keeping my Galaxy S5 for another year or so. Sorry Google. You just don’t get it.

catzwisker - Yanıt

Dude your S5 is way way way wayyyyyy too old to even compare to a Pixel 2 XL, not to mention the Pixel 4 XL. I guess you haven’t tried the new gen phones. You should try them and think again.

Ivo Ruest -

Umm, the Galaxy S5 only has 2 GB of RAM and it’s a slower LPDDR3, with a battery that’s only 10.78 Wh (2800 mAH) (Samsung Galaxy S5 Teardown ). It’s time to upgrade! Toss the S5 to Verizon as $450 in trade-in towards the Pixel 4 XL and you’ll be a happy camper.

CallMeIvan -

Trying to make sure my magnetic mount ring doesn’t obstruct the wireless charging coil.. how off center of the case is the coil’s center? Thanks

Peter Lau - Yanıt

Here is a shot of the glass back. The intersection of the blue lines marks the back’s center, which is slightly above the charging coil’s center.

Arthur Shi -

Thanks, that helps! I think I got it.

I realize a ruler laid along the length/height and width of the phone would be a helpful photo too. But this has been a big help.

Peter Lau -

I got a question! Isn’t it bad for the RAM to be layered over the SoC? I mean, all the heat the SoC produces will first spread to the RAM then it will be dissipated. It feels somewhat weird, altough it works (OEMs has been doing this as far as I can remember)

Renan Lazarotto - Yanıt

The radar almost certainly is not entirely contained in the pictured assembly. It shows a PCB antenna and some passive components - resistors, capacitors and inductors - but no active components, unless there is a die embedded in the PCB, which I doubt. There is probably an ASIC somewhere else in the phone that is energizing the PCB antenna and processing the received signals. I’d follow the flex traces back from the antenna and passives to see what active device is energizing them.

Max Kingsbury - Yanıt

Check the comments on that step. There a multiple companies making single chip radar solutions.

Jeremy Mikesell -

Definitely not worth it for the price. I’d rather buy a 11 Pro for a higher price. Google isn’t made for making for phones, this isn’t their area of expertise. This is why I think that this phone isn’t such a huge tech bump, unlike the 11 Pro, which was a giant leap for iPhone. Other than the 90Hz screen at higher resolution and the extra RAM, it is nothing comparable to 11 Pro. I used to hold high expectations for the Pixel series, this phone disappointed me.

Stanley Qiu - Yanıt

Yeah Google here with their neural core, audio processing and a bunch of other chips that no other manufacture have and yet it's still not worth it because on paper the specs doesn't look the best. You should try using it before you have a negative opinion.

edisonchoa -

could you remove the display without breaking it?

Sehoon Yoon - Yanıt

It is theoretically possible, but highly difficult due to the large amount of strong adhesives coupled with a fragile unreinforced OLED panel.

Arthur Shi -

do you know where is the esim chip ?

leesonwu - Yanıt

Anywhere know where the dual-frequency BCM47755 GNSS receiver is located?

Dominic - Yanıt

I have found a 4220mah battery for the xl, has anyone ever tried this upgrade?

Joey De La Rosa - Yanıt

do you know if there’s a DisplayPort over type-c chip on it?

Zhuijun Bao - Yanıt

Will this ram chip fit over the SoC and work.

My Pixel 1 (silver) was the most beautiful pixel ever produced. it was beautifully designed device in every aspect, internal and specially external,

somehow with every new pixel its getting more and more ugly. Not to mention bigger, for god sake bigger does not mean more customers ! please stop this non-sense of phones the size of my laptop!

ibrahimyounes - Yanıt

Fellow phone technician here. i want everyone to know to not use a hotplate and very low heat to remove the back glass for repairs. the microphones and speaker circuits are very delicate to heat and static (found this out from an oem service provider after the screen repair). Im just not wanting my pricey mistake to repeat itself onto other technicians
