In this video I’m going to take apart theGalaxy S7 Edge and talk about reparability.
Plus we’re going to cut open the heat pipewhich they’re calling 'liquid cooling', and at the end, I have some interesting stuffto show you with the camera so buckle up.
The easiest part of this whole project isremoving the SIM card/SD card tray from the phone so set that off to the side.
Make sureyou keep all your stuff organized.
And we are going to use a heat gun to heat up theback glass panel of the phone.
Basically what we’re trying to accomplish here is to softenthe adhesive underneath the glass panel so the glass panel will come off in one piecewithout cracking.
I’m heating up the phone to just hotter than I can touch, where I don’twant to leave my finger on there for longer than a second.
Then I’m going to take alarge suction cup.
I’m using a car windshield mount.
Suctioning it to the back of the glassand lifting up ever so slightly, just relieving some of the pressure on the glass betweenthe frame and the glass itself so I can slide a thin metal pry tool in-between the two layers.
Once I have that pry tool in, that is the hardest part.
Then I can take my heat gunand heat up the glue again.
I can slice away the glue a little bit with my pry tool butI can’t get along the edge of the phone or else I’m going to crack the glass.
Thisis where the business cards or playing cards come in because they can curve along the edgeof the Galaxy S7 Edge without cracking the glass.
I’m going to speed this part up alittle bit.
You can see I’m just cutting through the adhesive with my playing cardsall the way around the outside and that’s all there is to it.
Don’t go too deep oryou will cut into the Qi charger; I imagine most of you want to keep that.
Move the backglass panel.
You can see here the camera lens.
You can just push those through, that’show those are replaced.
Then there are 12 screws holding down the back the back frame.
I will link all the parts and tools down in the video description right below that “like”button.
There’s this nifty little piece of gold tape.
I have no idea what it doesbut it’s probably important so set that off to the side where you can remember whereit is.
Then there are a bunch of little plastic pieces around the edge of the phone.
They’relocked together like little puzzles.
So I’m going to snap off this top piece and set thatoff to the side next to the screws.
Then the Qi charger, panel and plastic will lift offfrom the back of the phone as well.
It just unsnaps from the bottom plastic piece.
Youcan see here the contact points of how the Qi charger charges the battery through themotherboard.
I’m going to unplug the battery now so that there is not any electricity coursingthe board.
Here’s the power button cable, the screen ribbon cable, and then here’sthe volume rocker cable as well.
The bottom loud speaker pops off and then here are thetwo contact points that rest on the motherboard so it gets its signal.
Here’s the fingerprintscanner and then here are some signal wires.
So I’m just going to pop those off withmy plastic pry tool.
You can also lift them off with a pair of tweezers.
Here’s theearpiece ribbon; it’s just like a little Lego, just unsnap it.
Then here’s the 5megapixel front camera.
It’s a cute little guy.
Set that off to the side.
Here’s forthe front sensors I’m going to pull that off.
And then there’s one more ribbon cabledown at the bottom of the phone for the charging port.
I’m going to unsnap that from theback of the motherboard.
And then here is the motherboard itself.
Once I flip it overyou can already see some discoloration where the processor has melted into the back plastic.
The 820 is a pretty hot running processor.
Here is a 12 megapixel rear facing camera.
I have some cool stuff I’m going to show you with this towards the end of this video.
I’m going to put it back into place, just snapping it in like a little Lego.
For thebattery removal process it is fairly difficult.
I’m going to use my heat gun again to softenthe adhesive between the battery and the frame of the phone.
And then using a metal pry toolvery very gently and very carefully prying it out of the metal frame.
You want to makesure not to slide or slice your metal pry tool at all because if you puncture the batteryit could smoke or explode.
You know, and we try to avoid doing those things.
Now downby the charging port there are three screws.
You can also remove the headphone jack.
Nowhere is the disappointing part of this phone.
The charging port has these two side ribbonsthat go around to the “back” and the “menu” buttons for the Galaxy S7 Edge.
And theseare tacked underneath the screen.
So in order to remove the charging port you will haveto remove the screen and the bad thing about that is that the Galaxy S7 Edge has the Edgeon the amoled and that is near impossible to remove from the frame without damagingit permanently.
So a charging port repair is pretty impossible with this phone unlessyou are doing a screen repair at the same time.
So remove the screen from the frameyou’re going to use the same process that you use for the back of the phone with playingcards and heat.
It w will destroy the old screen though so make sure that you do havea working replacement.
A glass only screen repair for this phone would honestly be thebest option with this phone, but those liquid nitrogen machines cost thousands of dollars.
My dry ice trick only works with iphones and not Samsung devices.
Hopefully the screenon the regular Galaxy S7 is easier to replace.
We’ll find out when I do my tear down thisweek.
So let’s do something fun.
We’re going to jump in and take apart that heatpipe that sits on top of the snap dragon 820 processor.
I’m going to take my razor bladeand slice into it and lift up the copper so we can see the insides.
So a heat pipe basicallyhas some vapor inside.
This particular heat pipe there isn’t any visible liquid likethere was with the Sony Xperia Z5 Premium.
We could see a little bit of liquid insideof that one.
This one is more similar to the Lumia 950 XL where there’s no liquid inside.
So here’s poll question for you.
There’s going to be a little icon that pops up inthe corner of this video.
Should a heat pipe inside a cell phone be called liquid coolingwhen there isn’t any visible liquid? Go ahead and respond to that quiz and we’llsee what the consensus is.
Inside the heat pipe there are these little copper strandsthat essentially wick the vapor inside of the tube from one end to the other as it heatsup.
So it does work as a glorified heat sink.
I’m going to put it all back together andit is as good as new.

I’mgoing to put the tape back on top with the little foam heat transfer bits and then wecan start putting the phone back together again.
I’m going to put the headphone jackback in by the charging port and then snap the charging port ribbon cable back into thebottom of the motherboard.
Set that back into place making sure to get all the wires andstuff out from underneath it; that includes the two up by the earpiece, the volume rockers,and the power button connector as well.
I’m going to snap all those back into place, makingsure that I can feel them click in underneath my finger just like a little Lego snappingin.
Same thing with the fingerprint scanner and all three signal wires.
Battery goes intoplace and before I connect that I want to make sure everything is plugged in.
So I’mgoing to get the charging port screwed back into place with the loud speaker set downon top of that.
5 megapixel front camera goes in, and then I can plug the battery in.
Oncethe battery is plugged in I can turn on the phone and I’m going to do that to test thescreen and to show you guys the camera.
Now this is pretty cool.
It’s called opticalimage stabilization.
The camera itself is stabilizing while I move it around.
And thisis what is going to keep your videos and images clear while you’re walking or holding yourphone.
There are two ways to stabilize images: there’s optical image stabilization andthere’s digital image stabilization.
The digital is just a software where it takesthe megapixels and kind of cuts off the corners of it and can stabilize it that way.
I preferthe optical stabilization where it’s actually a mechanical part of it with the little gyrosand magnets and little rubber balls inside the camera unit.
Pretty nifty stuff.
Onceall the screws are back into place you can take your double sided tape and put it aroundthe edges that way your new back will sit in place and stay on.
I will link all thereplacement parts and stuff down in the video description below just like all my other videos.
