Galaxy S7 Complete Tear down – Screen replacement, Charging port fix

Galaxy S7 Complete Tear down – Screen replacement, Charging port fix


Today I’m going to show every part of the
regular size Galaxy S7 screen and charging port replacement. The phone does get sacrificed
during the process so it should make for an interesting video. [electronic beep noise] First turn the phone off. Then the easiest
part of this whole repair will be removing the SIM card and SD card tray from the top.
Now to remove the back panel we will use a heat gun to help soften the adhesive underneath
the back glass. After heating the phone up for a couple seconds it’ll be too hot to
touch and we can stick a giant suction cup on it to gently lift up and away from the
phone as we slide our metal pry tool in-between the glass layer and the phone layer. This
is the hardest part of the whole removal process. So once you have it started, you’re probably
good to go. That little gap will let us slide a playing card or business card in-between
the glass and the frame and then we can slide that around the glass edges because the business
card will go with the curve of the back glass. I’m also putting playing cards underneath
the glass so it won’t re-adhere back down to the phone again as I’m removing the adhesive.
Once you’ve sliced through the adhesive on both sides make sure you don’t go too
deep or you will cut into the Qi charger. Then you can remove the back panel. If you
need to replace the camera lenses you can just push those through the back frame. Then
there are 12 screws around the back side of the phone. Now this little gold ticket gets
you one free chocolate candy bar from Willy Wonka’s chocolate factory, so set that off
to the side and save it for later. Then the plastic loud speaker can be removed from the
bottom of the phone. Same thing with the Qi charger, and then the plastic bit at the top.
The nice thing about having a Qi charger that doesn’t go through the charging port is
that if your charging port breaks, your Qi charger will still be able to charge your
phone through the contacts on the motherboard. I’m disconnecting all these little ribbon
cables starting with the volume rocker, the ear piece, the front sensors, the screen and
the battery. You should probably start with the battery and then the power button is off
to the side over there. Down here at the bottom of the phone there is the finger print scanner
and then a couple wire cables. You don’t need to disconnect the back one, I just got
a little disconnect happy and popped it off anyway. Then you can lift the motherboard
away from the phone just like in the Galaxy S7 Edge there is one little cable at the bottom
of the motherboard. Just unsnap that like a little Lego and the motherboard is removed
from the phone. Here is the front facing camera; it’s a 5 megapixel. Just unsnap that like
a Lego and then the rear facing camera on the motherboard here snaps off the same way.
It is clicked into the motherboard to this little plastic frame so you have to unsnap
that and then the camera can be removed. Now this phone has been on for a total of 30 seconds.
This tape sits right on top of the processors and with that much discoloration I wonder
if these phones are going to have over heating issues later on. I guess we’ll find out.
Here’s another look at the cameras. The top one is the 5 megapixel front. The bottom
one is the 12 megapixel rear. I’m going to go ahead and snap those back into the motherboard,
just like little Legos, you’ll feel them click into place. With the rear camera you’ll
also feel the camera unit itself click in cuz that plastic frame holds pretty tight.
Now the battery removal will need a metal pry tool. I’m going to use the blunt end
of this metal spudger. Just slip it in and then pry up little by little all around the
edge of the battery. Make sure you do not puncture the battery at all. There is the
battery itself. I will link replacement parts down in the video description. There are 3
screws down here by the charging port. That allows you to remove the headphone jack. Set
that off to the side. Now this is where the problem starts. This is the exact same as
the Galaxy S7 Edge where the “back” button and the “menu” button wrap around underneath
the screen of the phone so it makes the charging port repair impossible unless you remove the
screen of the phone. Now I assumed that removing the screen of this phone would be easier than
with the Galaxy S7 Edge and I was wrong because the screens are constructed differently. And
I’ll show you why. So I’m heating up the phone. I slipped a playing card in underneath
where the battery was at all the way to the edge of the screen and that allowed just enough
separation between the screen and the metal frame that I could slip my metal pry tool
it. Same thing with the back of the phone, I slipped the playing cards in so it doesn’t
re-adhere back down on top of itself. And I’m just working my way around the edges.
The screen is not going to survive this process. Tried the same trick with the other side,
slipping a business card in and hoping that that would lift off the other side of the
adhesive. Now down here at the bottom you do have to watch out for the charging port
buttons; the “back” button and the “menu” button. And here’s where I broke my screen,
right here on this corner. I nicked that corner and that made a crack all the way through
the LCD. It is super super fragile. That’s why I say that nothing is salvageable when
you are removing the screen from your device. So a charging port repair is most likely going
to require a screen repair as well. Here’s the other difference: the glass and polarizer
are not glued to the amoled screen. Normally, like with the Note 5 and other Samsung phones
everything is glued together so it’s more structurally sound. This screen is not. It
is much thinner and does not have the glue there. So now that I’ve severely destroyed
my screen, I’m just going to pull that away from the phone. I will link replacement screens
down in the video description. I will need to replace this one believe it or not. Here
are the three layers. We’ve got the glass and polarizer that are separated from the
amoled screen. But now that the screen is off, that will allow us access to the Home
button and fingerprint scanner, as well as the charging port. So I want to point out,
look how thick this aluminum chassis is. No wonder it survived my bend test. Now that
we have access to the Home button we can just pop that out from the back side and then slip
it through the little hole in the frame. Set that off to the side with all the other components.
And then right here this is where the buttons are wrapped around the mid-frame and attached
to the other side. So I’m going to lift those off gently and stick them through the
mid-frame and then I can lift the charging port off of the mid-frame. This is the charging
port; usually they’re pretty cheap, right around 10, 15 maybe 20 bucks. If only it was
easier to get at it would make this phone a lot more repairable. Here are all the components.
If you have any questions leave them down in the comments. I will make a Part 2 to this
video where I reassemble everything once I’ve purchased the new replacement screen. Thanks

  1. …Yeah, definitely not going to repair my charging port. Wish me luck backing up all my files to the cloud instead of a simple drag and drop.

  7. I work in a phone repair/accessory place and my boss replaced the charging port for me without changing the screen, I knew he was good, didn't realise HOW good until now…

  9. Excellent jerry, i did reinstall my golden ticket however. so i'm screwed out of the wonka factory trip once again :/

  10. Te charging port in my s7 got damaged the first week I got it, probably from a light rain. I was worried that it wouldn't get repaired on the warranty, so I did nothing about it for 8 months. When I did, I payed nothing for the repair. I have since even washed it under a tap, and nothing happened. I wonder what the problem was…

  11. Thanks so much for the video! You just reminded me I have wireless charging, after I googled qi….lol… I totally forgot, but am happy I can charge wireless because I broke my charging port😭

  12. You can remove the screen. Gotta go top down. And if you're careful and take your time. It's rather easy. Plus the glass is adhered 😉

  13. Zack I am awaring you that you will be going to have a weak memory in the future and you will always forget to remove the simcard tray from the phone. So don't wait go to the doctor.

  16. Does anybody know where can i find the just the black plastic that cover the back and menu bottom that goes on the lower part of the screen?

  17. @JerryRigEverything I watched this video at .25 speed and it was hilarious. It makes you sound really drunk. Give it a shot if you want a good laugh. Have a good Christmas!

  18. I just change my battery and it seems like my signal port got damaged and I cannot receive or send messages or calls… should I change the antenna cover?

  19. first 20 seconds are wrong, my tray is jammed and the only way I can get it out is to get in to the phone first hahahaha

  20. This is old.. also Not what I thought it was gonna be like but I can’t stop watching?! Might just have to subscribe

  21. I know this video is 3 years old now but about a year ago my wife's S7s battery got punched and I had to get to new S9s but she had over 1k pictures of our young kids and stuff on her S7 With this video I was able to pull her mother board and put it in to my old S7 and get everything off of her mother board. So thank you so much for doing what you do!
