Samsung Galaxy S3 Not Connecting T…
First, let's give thanks where thanks are due: a big, solid, awesome thanks to Chipworks for providing the pictures for this teardown. We greatly appreciate their help for the Samsung Galaxy S III!
Here's their full analysis on the Galaxy S III.
Arguably the most hyped-up Android phone to ever hit the market, the Samsung Galaxy S III has an impressive list of accolades. Here are some of the heavy-hitting tech specs:
Android 4.0 Ice Cream Sandwich
4.8' Super AMOLED 720 x 1280 resolution display
1.4 GHz quad-core application processor
2100 mAh battery
8 MP rear-facing and 1.9 MP front-facing cameras
16, 32, or 64 GB of internal storage
Pictured here next to the Samsung Galaxy S2 (left) for comparison.
The simple, sleek design of the newest Galaxy S implements a standard power/sleep button on the side of the device.
As we ready ourselves to dig into this Galaxy S, it watches us with its rear 8 MP camera. To the left and right of the camera are the flash and speaker assemblies.
The Galaxy S is not only watching us, but listening, as well.
Much like in the Galaxy Nexus, we find a user serviceable battery in the Samsung Galaxy S III.
The 3.8 V, 2100 mAh battery incorporates the antenna for the Near Field Communications (NFC) module used in 'S Beam'.
For those who are curious, 2100 mAh is equivalent to 7560 Coulombs of charge. Unsurprisingly, this is the same amount of charge that a 3.8V, 7.98 Wh battery holds.
Well this is interesting. It would seem Samsung wants us to 'refer to [the] manual before using [the] battery?' Yeah, like that's gonna happen...
Internals time. The spudger takes care of the first two plastic assemblies.
The first piece out is the rear plastic frame that protects the motherboard and houses a single liquid indicator sticker.
Removal of the frame grants us access to an easily replaceable speaker assembly.
The big question now is what we should remove first. So many components in such a small volume!
Rear-facing camera you say? Sure, let's pry that 8 MP behemoth of a camera out from the inner framework.
We continue by removing the motherboard from the inner framework.
With the motherboard out of the way, we can get a good look at the inner support frame. While we suspect that the frame is probably magnesium, we do not yet have any concrete proof.
We find a chip that isn't attached to the motherboard: a Melfas 8PL533 Touch Sensor that translates your touch inputs into zeroes and ones.
Let's talk tools for a minute.
We don't just make awesome teardowns—we sell parts. And tools! Lots and lots of tools.
Like this handy-dandy electronics tool kit that we used to take apart the new iPad. You know you want one. It'll pay for itself the first time you use it!
We sell Mac parts & upgrades, parts for iPhone screen repair, kits for fixing the infamous Xbox Red Ring of Death, and tons more.
We need your support to continue building the free repair manual for everything in the world.
Chipworks eagerly provided us with pictures of the motherboard less than an hour into the teardown! Here is the front of the motherboard:
Murata M2322007 WiFi Module
Samsung Exynos 4412 quad-core A9 processor with 1 GB LP DDR2 Green Memory (K3PE7E700M-XGC2)
Samsung KMVTU000LM eMMC(16GB)+MDDR(64MB) NAND Flash
Intel Wireless PMB9811X Gold Baseband processor
MAX77693 and MAX77686
Broadcom BCM47511 Integrated Monolithic GNSS Receiver
33ODC 2214 4TP AC
Bottom of motherboard:
Wolfson Microelectronics WM1811 stereo codec
Skyworks SKY77604 Multi-Band Power amplifier
Silicon Image 9244 low-power MHL Transmitter
NXP PN544 NFC Chip.
Infineon PMB5712 RF transceiver
The glass is fused to the display, and the display to the Galaxy S III's frame.
This will greatly increase the amount of money one has to spend when replacing the glass, should one be unfortunate enough to break it.
Some more shots of that saucy camera, including a Chipworks x-ray!
Chipworks report that the camera has a Sony BSI sensor. Contrary to earlier reports, their initial inspection suggests it is a new sensor, and not the same one used in the iPhone 4S. The bond pad arrangement is not the same as the IMX145 found in the iPhone 4S nor is it the same as the IMX105 found in previous Samsung phones.
Update: This teardown was conducted solely via Interweb, requiring us to defer judgment on a repairability score. Now that we've worked on it ourselves, we can assign it a fair score:
Samsung Galaxy SIII Repairability Score: 8 out of 10 (10 is easiest to repair)
The battery can be replaced without any tools.
Very easy to open and access internal components.
There are only 12 screws in the entire device, all standard Phillips #0 (no proprietary or security sizes).
Smaller components (antennas, vibrator, light sensor) are modular and can be replaced individually, but are adhered to the front panel.
The glass is fused to both the display and the display frame, increasing repair costs.
You'll have to go through the entire phone in order to replace the front panel, since everything is built into the back of it.
