In this video I’m going to take apart the
Galaxy S7 Edge and talk about reparability. Plus we’re going to cut open the heat pipe
which they’re calling ‘liquid cooling’, and at the end, I have some interesting stuff
to show you with the camera so buckle up. The easiest part of this whole project is
removing the SIM card/SD card tray from the phone so set that off to the side. Make sure
you keep all your stuff organized. And we are going to use a heat gun to heat up the
back glass panel of the phone. Basically what we’re trying to accomplish here is to soften
the adhesive underneath the glass panel so the glass panel will come off in one piece
without cracking. I’m heating up the phone to just hotter than I can touch, where I don’t
want to leave my finger on there for longer than a second. Then I’m going to take a
large suction cup. I’m using a car windshield mount. Suctioning it to the back of the glass
and lifting up ever so slightly, just relieving some of the pressure on the glass between
the 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 gun
and heat up the glue again. I can slice away the glue a little bit with my pry tool but
I can’t get along the edge of the phone or else I’m going to crack the glass. This
is where the business cards or playing cards come in because they can curve along the edge
of the Galaxy S7 Edge without cracking the glass. I’m going to speed this part up a
little bit. You can see I’m just cutting through the adhesive with my playing cards
all the way around the outside and that’s all there is to it. Don’t go too deep or
you will cut into the Qi charger; I imagine most of you want to keep that. Move the back
glass panel. You can see here the camera lens. You can just push those through, that’s
how 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 does
but it’s probably important so set that off to the side where you can remember where
it is. Then there are a bunch of little plastic pieces around the edge of the phone. They’re
locked together like little puzzles. So I’m going to snap off this top piece and set that
off to the side next to the screws. Then the Qi charger, panel and plastic will lift off
from the back of the phone as well. It just unsnaps from the bottom plastic piece. You
can see here the contact points of how the Qi charger charges the battery through the
motherboard. I’m going to unplug the battery now so that there is not any electricity coursing
the board. Here’s the power button cable, the screen ribbon cable, and then here’s
the volume rocker cable as well. The bottom loud speaker pops off and then here are the
two contact points that rest on the motherboard so it gets its signal. Here’s the fingerprint
scanner and then here are some signal wires. So I’m just going to pop those off with
my plastic pry tool. You can also lift them off with a pair of tweezers. Here’s the
earpiece ribbon; it’s just like a little Lego, just unsnap it. Then here’s the 5
megapixel front camera. It’s a cute little guy. Set that off to the side. Here’s for
the front sensors I’m going to pull that off. And then there’s one more ribbon cable
down at the bottom of the phone for the charging port. I’m going to unsnap that from the
back of the motherboard. And then here is the motherboard itself. Once I flip it over
you 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 the
battery removal process it is fairly difficult. I’m going to use my heat gun again to soften
the adhesive between the battery and the frame of the phone. And then using a metal pry tool
very very gently and very carefully prying it out of the metal frame. You want to make
sure not to slide or slice your metal pry tool at all because if you puncture the battery
it could smoke or explode. You know, and we try to avoid doing those things. Now down
by the charging port there are three screws. You can also remove the headphone jack. Now
here is the disappointing part of this phone. The charging port has these two side ribbons
that go around to the “back” and the “menu” buttons for the Galaxy S7 Edge. And these
are tacked underneath the screen. So in order to remove the charging port you will have
to remove the screen and the bad thing about that is that the Galaxy S7 Edge has the Edge
on the amoled and that is near impossible to remove from the frame without damaging
it permanently. So a charging port repair is pretty impossible with this phone unless
you are doing a screen repair at the same time. So remove the screen from the frame
you’re going to use the same process that you use for the back of the phone with playing
cards and heat. It w will destroy the old screen though so make sure that you do have
a working replacement. A glass only screen repair for this phone would honestly be the
best 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 screen
on the regular Galaxy S7 is easier to replace. We’ll find out when I do my tear down this
week. So let’s do something fun. We’re going to jump in and take apart that heat
pipe that sits on top of the snap dragon 820 processor. I’m going to take my razor blade
and slice into it and lift up the copper so we can see the insides. So a heat pipe basically
has some vapor inside. This particular heat pipe there isn’t any visible liquid like
there was with the Sony Xperia Z5 Premium. We could see a little bit of liquid inside
of 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 in
the corner of this video. Should a heat pipe inside a cell phone be called liquid cooling
when there isn’t any visible liquid? Go ahead and respond to that quiz and we’ll
see what the consensus is. Inside the heat pipe there are these little copper strands
that essentially wick the vapor inside of the tube from one end to the other as it heats
up. So it does work as a glorified heat sink. I’m going to put it all back together and
it is as good as new. Hit that subscribe button if you’ve enjoyed this video so far. I’m
going to put the tape back on top with the little foam heat transfer bits and then we
can start putting the phone back together again. I’m going to put the headphone jack
back in by the charging port and then snap the charging port ribbon cable back into the
bottom of the motherboard. Set that back into place making sure to get all the wires and
stuff 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, making
sure that I can feel them click in underneath my finger just like a little Lego snapping
in. Same thing with the fingerprint scanner and all three signal wires. Battery goes into
place and before I connect that I want to make sure everything is plugged in. So I’m
going to get the charging port screwed back into place with the loud speaker set down
on top of that. 5 megapixel front camera goes in, and then I can plug the battery in. Once
the battery is plugged in I can turn on the phone and I’m going to do that to test the
screen and to show you guys the camera. Now this is pretty cool. It’s called optical
image stabilization. The camera itself is stabilizing while I move it around. And this
is what is going to keep your videos and images clear while you’re walking or holding your
phone. There are two ways to stabilize images: there’s optical image stabilization and
there’s digital image stabilization. The digital is just a software where it takes
the megapixels and kind of cuts off the corners of it and can stabilize it that way. I prefer
the optical stabilization where it’s actually a mechanical part of it with the little gyros
and magnets and little rubber balls inside the camera unit. Pretty nifty stuff. Once
all the screws are back into place you can take your double sided tape and put it around
the edges that way your new back will sit in place and stay on. I will link all the
replacement parts and stuff down in the video description below just like all my other videos.
