Samsung Galaxy S7 Repair In Kolkata
There are no exterior screws are there, Only a dark colored glue sticking the two matters tightly in this case.
With the rear glass lifted by a smidge, we attack with an opening pick and slice apart the adhesive.
we now find gooey black adhesive
Removing the back cover hasn’t given us access to anything useful—just a smooth surface for the glass to stick to.
Fortunately, part of that surface consists of screws.
Actually, that smooth surface contains its speaker
We line up the pieces for a closer look at the individual components, including the wireless charging coil.
Last year’s Galaxy flagship had a single midframe with a handful of aggressively adhered parts.
All these modular components connect to the motherboard by way of tiny spring contacts, making removal and replacement a snap—once you’ve muscled your way past all the glue and glass, anyway.
Samsung got some flak from consumers for reducing battery capacity in last year’s S6. It seems they took the hint and made up for it by including this 3000 mAh battery in the S7.
Working our way to the motherboard, we pluck out a 5-megapixel front-facing camera.
The only front-facing camera upgrade here is the shiny new ƒ/1.7 aperture.
With the front camera out of the way, we lift up the motherboard and find a familiar daughter-board connector on its underside.
S7 got a downgrade with a 12-megapixel/4K rear camera .
However, the sensor in the S7 sports Dual Pixel autofocus technology (a.k.a. phase detection) for every pixel.
Additionally, these pixels measure in at 1.4 µm—a full 25% increase from last year’s model—which will reduce noise and improve overall image quality.
So, despite having fewer pixels, even photos taken in the worst lighting should come out clearer in a head-to-head comparison.
quirreled away under the EMI shields, we find:
SK Hynix H9KNNNCTUMU-BRNMH 4 GB LPDDR4 SDRAM layered over the Qualcomm MSM8996 Snapdragon 820
Samsung KLUBG4G1CE 32 GB MLC Universal Flash Storage 2.0
Qualcomm WCD9335 Audio Codec
And some more:
Avago AFEM-9040 Multiband Multimode Module
Murata FAJ15 Front End Module
Qorvo QM78064 High Band RF Fusion Module
Qorvo QM63001A Diversity Receive Module
DSP DBMD4 Audio/Voice Processor
And on the flip side…
Samsung 1316S7 Wi-Fi Module
NXP 67T05 NFC Controller
IDT P9221 Wireless Power Receiver (likely an iteration of IDT P9220)
STMicroelectronics LSM6DS3 always-on 6-Axis IMU
Qualcomm PM8996 PMIC
Qualcomm QFE3100 Envelope Tracker
Qualcomm WTR4905 and WTR3925 RF Transceivers
Next up is the S7’s modular headphone jack.
Complete with cute rubber seal!
We find more rubber seals around the lower microphone and speaker making for some serious ingress protection.
Just like its predecessor, the cables for the S7’s soft buttons are wrapped around the display-backing frame.
These sandwiched cables make a daughter-board replacement (including the charging port) next to impossible, since freeing these cables means removing the OLED screen.
Undaunted, we bring back our iOpener to ease the tension adhesive.
While we’re at it, we grab a trusty opening pick and set to work on the terrible task of prying open the OLED.
Peeling up those pesky soft button LED cables lets us finally free the daughter-board.
Just for those of you keeping score, this messy situation prevents easy replacement of: display and digitizer (of course), USB port, microphone, and soft button LEDs.
If you need to replace the charging port, unless you have some microsoldering skills, you have two options: sacrifice those soft button LEDs or replace your display in the process.
Remember that fake “midframe” made of antennas? Turns out the S7 just buried its midframe deeper, and adhered the display to it, rather than secure its display assembly to a midframe with screws.
This beefs up the S7’s waterproofiness, but means more of a fight to repair the thing should you suffer non-water related troubles.
Alright, the moment we’ve all been waiting for: the legendary “liquid cooling” system in the S7.
It’s a tiny copper twig.
Actually, it’s a teeny heat pipe (thin copper tube) with less than half a gram of material, measuring less than half a millimeter thick.
This may not be as revolutionary as Samsung describes it, but most heat pipes do technically use liquid to transfer heat.
In the case of the S7, we’re guessing that the pipe transfers heat to the phone’s metal midframe, where it can then radiate out to the side—or directly into your hands.
We’ve seen heat pipes in phones before, but the growing need for them shows how phone processors are getting faster (and sometimes hotter) each year.
Many components are modular and can be replaced independently.
Unlike the S6 Edge, the battery can be removed without first ousting the motherboard—but tough adhesive and a glued-on rear panel make replacement more difficult than necessary.
The display needs to be removed (and likely destroyed) if you want to replace the USB port.
Front and back glass make for double the crackability, and strong adhesive on the rear glass makes it very difficult to gain entry into the device.
Replacing the glass without destroying the display is probably impossible.
