All right, today I'm going to show you how to replace just the glass on a Samsung Galaxy
S5.
This is one of the newer phones that just came out, and everything on this phone is
working perfectly except that the glass is cracked.
Now you have a couple options.
One is just to buy the glass which is super cheap but it is very difficult to replace.
The second option is to buy the glass and the LCD combination.
It's more expensive but it is much, much easier to replace.
I will link both of those parts in the video description below and you can choose what
you want to do.
I am using some playing cards a screwdriver, and some tweezers to finish this repair.
I'm going to pop off the back cover of the phone, and then underneath this little plastic
piece right here there's a little ribbon cable that we're going to disconnect.
This ribbon cable goes to the home button on the Galaxy S5.
I'm going to pull out the battery, pull out the sim card, and I'm going to use a hot plate
in order to heat my phone up to the right temperature in order to separate the screen
from the rest of the body.
I like to heat it up to about 97 degrees Celsius which is about 206 degrees Fahrenheit.
There are a couple different ways that you can heat up the phone.
One is with a heat gun, so go ahead and click that top video if you want to watch how to
remove the screen with a heat gun, or you can watch the three common mistakes that people
make when removing just the glass.
I would recommend watching both of those videos if you're serious about this repair.
I'm going to use a knife to get started up in the top corner and then slip my playing
card inside, and this is just going help separate the adhesive from the phone body itself.
I'm not going to go too deep into the phone just yet, because there are two important
ribbon cables that are inside of there, and if you go too far you're going to rip them.
So make sure to watch farther ahead in the video as well to see where those ribbon cables
are and make sure you avoid them because if you do rip them, you'll have no option but
to buy the more expensive part.
I'm leaving the cards in there as I slide them in so the phone doesn't re-adhere to
itself.
Now that it's cooled down a little bit I'm going to go ahead and put it back on the heater,
the hot plate that I have, and once it's heated up for a minute or two I'm going to get back
at it again.
Once I have all the sides separated I'm going to use my red pry tool and slide it into the
phone to separate the adhesive that's holding the LCD down to the back of the phone as well.
The LCD to this phone is actually surprisingly resilient.
It doesn't break very easily.
I would be very careful though as you're sticking the pry tool down to not damage any of those
ribbon cables.
This one right here is one I'm disconnecting for the LCD.
And that's where it connects to the main board.
And then you can see as I'm pulling up the screen from the phone the little ribbon cable
that goes to the home button is also pulling through that back hole.
I'm going to heat up the screen again so I can pull up this last little bit.
The only thing that's holding the screen onto the phone right now is the cables that are
in charge of the back button and the menu button, so I'm going to scrape those off the
front glass with my knife, and then kind of press them down into the phone so that they
don't rip and they don't get in the way for later.
Now for the menu button.
And then I can just twist the phone off of the adhesive and pull it off of the main body.
This right here is the LCD and glass combination.
If this is the part that you're going to buy you can just go ahead and reattach that right
now and clip it back into place.
But if you're going to attempt to do just the glass repair then I'll show you how to
do that right now.
As you can see from the heat and the prying we almost separated the LCD from the glass,
you can see the glue kind of separated away.
I'm going to go ahead and test the phone right now to make sure everything is still working,
looks like it all turns on and functions.
Everything's working great so I'm going to use my hot plate again, set the screen down
on top of it, and let it warm up for a couple minutes.
Remember that you can use a heat gun and a temperature sensor.
I'll link these in the video description below.
And those will accomplish the same thing that the hot plate does.
Now that the screen is heated up to the right temperature I'm going to use my playing cards
again to separate the glass from the LCD.
And you can see as I go in the glue just kind of separates, you'll see it kind of streak
down the edges of the LCD as you kind of pull it away.
Also keep in mind that there are a million things that can go wrong as you're doing this.
So you do this at your own risk, and remember that you might need to buy the more expensive
part anyway if something goes wrong and your LCD stops working.
I'm going to put this screen up every time I reheat the phone.
Just to remind you what temperature it needs to be at.
You can see that the glass shards on this phone will come away individually.
They're not laminated like they were on the Galaxy S4.
I kind of liked that about the S4.
Because the screen is so thin, the window of opportunity that you have to pull off the
glass is relatively small because the screen cools down so quickly.
And when the screen cools down the glue is not as liquid between the glass and the LCD
and is much harder to separate.
If your phone has less cracks in it it will be easier to pull the glass away.
This phone was pretty obliterated so it makes it more difficult.
Anyway, still continuing on with the removal of the glass, if you're getting bored of this
whole process and watching me do it you can go ahead and skip to around minute 8 or 9
and that's when I start to re-adhere the new glass to the LCD using the UV light and the
UV glue.
So that's pretty interesting.
Anyway, each time your phone cools down, you need to make sure to heat it up to the right
temperature again, and a couple things to be aware of.
If you overheat your phone you're going to discolor the LCD.
Also when you're pulling away the glass shards from the body of the phone, if you pull up
one edge of the shard while the other shard is still adhered to the LCD, it's going to
put a lot of pressure on the LCD and could possibly crack it.
So you have to be super careful with that.
Now if you feel like you've learned anything or if you've just enjoyed watching this video
I would appreciate it if you'd subscribe to my YouTube channel.
I do put up videos pretty much every week.
Usually related to cell phone repair or automotive repair, you know fixing something here and
there.
JerryRigEverything, you can also follow me on Instagram @ZacksJerryRig.
It would be fun to see you around.
Also, while you're doing your own repair if you think of any more hints or things that
I left out of this video make sure to leave them down in the comments below for other
people.
It's always good to have a group conglomeration of ideas when attempting a project this hard.
Anyway, continuing onward with the cards, I'm just going to go around the edge of the
LCD super slow, you know slow and steady, make sure you don't break anything.
I would say that this whole entire project took me about two hours, two and a half hours.
If you're just planning on doing the LCD and glass swap, which is the more expensive part,
I would say the process would take about twenty five or thirty minutes.
Removing the glass is a little more complicated and you want to take your time, just so you
don't have to spend the extra money on the whole part itself.
Anyway we're getting closer here, all the big shards are pretty much taken away, I'm
going to head it up one more time.
You have about a thirty second window just because the glass is so small and so thin,
it doesn't retain heat very well so it cools down very quickly.
And that makes it harder when you're trying to keep the glue liquid so you can separate
the glass from the rest of the phone.
Anyway, now that there's just little shards left I've found that it was easier to go on
a kind of sawing motion with my card.
I would just run the edge of the card down along the pieces of glass and it would almost
twist them out instead of lift them up if that makes sense.
You can kind of see me do it here in the video.
For those of you in the future who are going to attempt this without a temperature sensor
to tell you what temperature the phone is at, you're going to want to heat it up to
the point that it's too hot to touch comfortably.
You won't be able to rest your finger on it for more than maybe a second at a time.
And then you'll know that the glue between the glass and the LCD is ready to be separated.
Anyway, as you can see the whole slicing motion with the card works pretty well to get the
little shards off, I'm just going to town on those right now.
I'm brushing away the little bits as well the to keep the screen as clean as possible.
This last little bit went pretty quick.
I have this whole process sped up right now to about 400% so it's 4 times faster than
how I normally did it.
All right, now I'm going to make sure I didn't break anything on the screen, pop the battery
in, plug it in, and it looks like everything's still working, so I'm still good to go with
just the glass repair.
Now if something wasn't working at this point, you're going to have to buy the more expensive
part and roll with that.
Now right here in order to get the rest of the glue off I've found that the easiest way
is to just kind of roll it off with my fingers.
You can see that I'm just pressing up against it and just rubbing the glue off in little
rolls as I go down and this gets the big chunks of glue off that won't come off with the denatured
alcohol that I use once the main chunks are gone.
You can see me have a little rag right here and I'm just using the denatured alcohol to
get rid of the rest of the residue off of the LCD.
Pretty straightforward.
Now I'm going to put the home button back up just so I can use it to line up the glass
as I position it on top of the LCD again.
It makes it a little bit easier.
This is the UV glue.
Some people call it LOCA.
It's the optical grade ultraviolet adhesive.
I've linked it in the video description below, so you can check that out and get it there.
With the UV glue, it's a little bit easier with the Galaxy S5 than it is the S4, because
the runoff glue just ends up on the paper towel below you.
You want to put the glue on just like this so that when you place the glass on it, it
will run towards the edges.
And you'll see why in just a second.
Here's the glass.
Once again, you can find these in the video description below.
I'll link all the parts you need down there.
And I'm going to go super slow with this.
The slower you go the less bubbles you'll have under your screen.
I lined it up with the home button and I"m just starting very gently with the bottom
edge of the screen and slowly lowering it down on the glue.
You can see how the glue acts once the glass touches it.
I put my pair of tweezers under the glass and I'm still just going to lower it down.
If you do it any quicker than this, bubbles can form in the glass and it's super difficult
to get them out.
You have to kind of push them toward the edge of the screen.
It gets a little bit annoying.
So just go slow and steady, just like the rest of this repair.
Now that the glass is fully dropped on the screen, I can take my finger and press right
there in the center of it, and that'll make the glue run toward the edges.
Kind of sweet how this works.
Just press where you want and the glue goes out.
The nice part about this is that as I'm pressing it down the glue is going to kind of suction
the glass to the LCD.
And this is super important because when I'm going to line up the LCD with the glass I
can just lift the whole contraption up off of the paper towel, flip it over, and make
sure that the edges of the phone, as you can see the black line around the edge of the
copper there, is equal on both ends.
That's how you know the LCD is correctly positioned in the glass window.
So you won't have any lapse or gaps in the LCD when you're putting it back together.
I'm going to flip it over one more time and make sure that it's completely lined up as
well with the bottom.
And you can see that the glue seeped out the edges, this is totally normal.
And I'll show you what to do with that in a second.
K, so here's the UV light.
Once again, I'll put this in the video description below if you need to buy it, and you would
use this for any type of repair in the future.
UV glue is a great way to replace the glass on your screen.
It's not even very expensive.
Anyway, so I'm going to go ahead and just brush over the top really quick, and this
will kind of get it tacky underneath, the whole process only takes about a minute or
two for the glue to completely cure.
I'm just going to rest the light on top of the phone and let it sit there for a little
bit.
Now that that's done, I'm going to take a little rag and wipe away the excess glue along
the edge of the phone, making sure to get both sides down around the button.
And then I'm going to over it with the UV light one more time, just to cure any glue
that might have seeped out from around the edges.
And this will make it so you don't have any excess glue inside of your phone, which is
nice.
Now I'm going to test it and make sure everything works.
Going to clip that screen back in, put the battery in, and it looks like we're good to
go.
Everything is 100% functional, so the only thing we have to worry about now is making
sure that the glass, well the whole screen unit itself can be adhered back to the phone
body.
I"m going to clean down underneath the home button as well.
All right, so this is the double-sided sticky tape, I will link this in the video description
below as well, and I'm going to just go to town on the inside of the phone and put the
sticky tape everywhere.
I would make sure to focus on the edges of the phone as well as the top, making sure
not to cover anything important like the cameras or the home button.
And right now I'm going to take the back button and the menu buttons, the stuff that you peeled
off the front glass earlier, I'm just going to lay them in the little grooves that are
already made for them.
That way when I put on the front glass I don't have to worry about it.
I'm going to take off the paper from the double sided sticky tape and prep the screen to be
positioned back into place.
Remember the little ribbon cable that goes through this back slot, just kind of feed
that through to start off with.
Plug the screen in, make sure that it's working.
Everything's functioning well, so I can just take the screen and press it back into place,
making sure that it's completely stuck down along the tops, the edges, and the bottom.
I'm going to clip the ribbon cable down onto the main board underneath that little plastic
bracket thing, and snap the back cover in place.
And there you go.
Whether you did just the glass repair or you did the more expensive part, which is the
LCD and the glass, either way it is a very impressive repair.
