Este teardown (desmontagem analítica) não é um guia de reparo. Para reparar seu/sua Samsung Galaxy S9, use o nosso manual de serviço.

  1. Samsung Galaxy S9 Teardown, Teardown: passo 1, imagem 1 %32 Samsung Galaxy S9 Teardown, Teardown: passo 1, imagem 2 %32 Samsung Galaxy S9 Teardown, Teardown: passo 1, imagem 3 %32
    • This smaller version of the S9+ gets a big hardware upgrade. Let's take a look:

    • Notchless 5.8" AMOLED Display with resolution of 2960 × 1440 (~570 ppi)

    • Qualcomm Snapdragon 845 or Samsung’s own Exynos 9810, depending on location

    • 12 MP OIS dual-aperture main camera—f/1.5 and f/2.4 modes—plus an 8 MP selfie cam

    • Headphone jack and microSD slot

    • IP68 water/dust-proofing rating

    • Android 8.0 Oreo

    • We start with a sneak peek—X-ray intel provided by our co-conspirators at Creative Electron.

    • If you liked the S8, we've got good news—Samsung agrees with you. The design seems almost totally unchanged, save for the new (and better) fingerprint sensor location.

    • Our S9 cozies up to its S8 ancestor on the left (reassembled from our 2017 teardown) and its S9+ sibling on the right (still sore from our teardown last weekend).

    • Props to Samsung for keeping the headphone jack and expandable storage, all while maintaining IP68 protection.

    • Are these things new? No. Are they still good? We say yes.

    • Getting inside a Galaxy phone hasn't gotten any easier lately, but at least the procedure is familiar:

    • Step 1: get it hot.

    • Step 2: add more heat.

    • Step 3: suction and slice, and don't hit that fingerprint sensor cable that you can't see.

    • You've probably heard us complain about this before, so we'll just add this: yes it's risky and tedious, but at least if you crack the back glass, you stand a chance of being able to replace it economically. (Our favorite fruit company is still working on that one.)

    • Next we turn our attention to the brains of the phone, and after removing a few friendly Phillips screws, the motherboard slides free.

    • If this board already looks a bit worse for wear, that's because we previously removed the EMI shields for our video teardown. Give yourself a pat on the back if you noticed!

    • Near the top of the board we get a look at the S9's new heart rate and blood pressure sensors, a step up from the standard heart rate sensor seen on many phones.

    • This new blood pressure hardware works alongside a Samsung and UCSF co-developed research app to give users info about stress levels and blood pressure.

    • Say hello to Dr. Bixby.

    • Compared to some flagships, the S9 has twice the f-stops and half the sensors.

    • Not shown: Samsung's highly touted 2 Gbit LPDDR4 DRAM, layered right underneath the image sensor.

    • Shown: Some other mystery chips.

    • RD938 likely OIS driver

    • STMicroelectronics L2G2IS 2-axis OIS gyroscope

    • GigaDevice GD25LQ32 32 Mb serial flash

  6. Samsung Galaxy S9 Teardown: passo 7, imagem 1 %32 Samsung Galaxy S9 Teardown: passo 7, imagem 2 %32
    • We want to try out the S9's new dual aperture, but using the camera app seems a little too conventional.

    • After a bit of disassembly, a spudger seems to do the trick instead.

    • This may seem goofy, but the S9 really will have a small actuator that mechanically opens and closes the aperture—a mechanical bit that can fail.

    • Removing the lens also reveals the image sensor. Taking a closer look we see...yep that's an image sensor. Maybe some X-rays can show us that DRAM...

  7. Samsung Galaxy S9 Teardown: passo 8, imagem 1 %32
    • Lets take a look at the chips that power all that fancy hardware:

    • Samsung K3UH5H5OMM-AGCJ 32 Gb (4 GB) LPDDR4X DRAM, layered over a Qualcomm Snapdragon 845

    • Toshiba THGAF8G9T43BAIR 64 GB UFS (NAND flash + controller)

    • Avago AFEM-9096 front end module

    • Qualcomm Aqstic WCD9341 audio codec

    • Maxim MAX77705F PMIC

    • Skyworks SKY13716-1 low band front end module

    • IDT P9320S wireless power receiver likely similar to the P9320

  8. Samsung Galaxy S9 Teardown: passo 9, imagem 1 %32
    • There's another gathering of integrated circuits on the flip side:

    • Murata KM7N07016 Wi-Fi/Bluetooth module

    • NXP PN80T NFC controller

    • Qualcomm PM845 (likely PMIC)

    • Qualcomm SDR845 RF transceiver

    • Hard to make out, but we think this is likely the same Skyworks SKY78160-11 front-end module we found in the S9+

    • Qualcomm PM8005 PMIC

    • Qualcomm QDM3870 high-band diversity front-end module

  9. Samsung Galaxy S9 Teardown: passo 10, imagem 1 %32 Samsung Galaxy S9 Teardown: passo 10, imagem 2 %32

    • Samsung S2MPB02 camera power management

    • Samsung S2MPB03 camera power management

    • Samsung S2DOS05 display power management

    • Qualcomm D5319 mid-band diversity front-end module

    • RDA Microelectronics RDA6213N FM transceiver (likely)

    • Qualcomm QET4100 envelope tracker

  10. Samsung Galaxy S9 Teardown: passo 11, imagem 1 %32 Samsung Galaxy S9 Teardown: passo 11, imagem 2 %32
    • IC Identification, pt. 3:

    • NXP Semiconductor PCAL6524 24-bit I/O expander

    • ON Semiconductor FPF3688UCX load switch

    • Vishay DG2730 2-port, 480 Mbps USB 2.0 DPDT analog switch

    • ON Semiconductor FAN48618BUC53X 1 A boost regulator

    • Richtek RT8010GQW 1 A step-down DC-DC converter

    • Texas Instruments boost converter (likely)

    • NXP Semiconductor NCX2200 comparator

  11. Samsung Galaxy S9 Teardown: passo 12, imagem 1 %32 Samsung Galaxy S9 Teardown: passo 12, imagem 2 %32
    • IC Identification, pt. 4 (sensors):

    • STMicroelectronics LSM6DSL 3-axis accelerometer/gyroscope

    • AKM Semiconductor AK09916C 3-axis electronic compass

    • STMicroelectronics LPS22HB pressure sensor

    • heart rate sensor

    • Ablic (formerly Seiko Instruments) S-5712CCDL1-I4T1U hall sensor

  12. Samsung Galaxy S9 Teardown: passo 13, imagem 1 %32
    • From "S9" to "See ya later!" This teardown is toast!

    • We skipped a lot of the familiar details—if you haven't already, you can get the deeper dive into some similar Samsungs like the S9+, S8, and S8+.

  13. Considerações finais
    • Many components are modular and can be replaced independently.
    • The battery replacement is technically possible, but accessing it is an unnecessary challenge.
    • Glued-down glass both front and back means greater risk of breakage, and makes repairs difficult to start.
    • Screen repairs require a lot of disassembly while battling tough adhesive.

Hello:

So, no radio on this model either?

Thanx for another great video and teardown explanation : )

Héctor Gonçalvez - Responder

that was perfect

mohsen - Responder

Can you identify and break apart the RF front end please

Mikey W - Responder

Can the outer glass be replaced without replacing the entire lce

lovemolai - Responder

Technically but not worth the
