Alright today we’re going to take apart the GalaxyS4 Mini, which is the cute little
brother or sister to the Galaxy S4 made by Samsung.
First we’re going to take off the back which reveals the SD card and the SIM card.
So we’re going to take both those out.
And then here’s a diagram of the screws.
There are 10 of them.
Philips head.
So just make sure to take off all of those around the outside.
And then this bottom section right here is the loud speaker where your ringer and your
music come from.
You can see that the speaker right here is on the left side and there are just two little
pins that touch when it’s down connected to the motherboard.
And that’s where it gets its feedback from.
So you take off the outer ring…the outer plastic of the phone.
I’ve found that it’s easier to put my finger in where the battery goes and kind
of pull it away from the back of the screen and that gives just enough of a gap to put
my pry tool in there and kind of swing it around the outside edge and un-pry it from
the phone.
Here is the ribbon cable connector for the charging port which allows the bottom section
of the motherboard to lift up.
Here is the front camera and then the ear piece and proximity sensors, and then the
headphone jack.
All of these are like little Legos that just snap on and off.
And be very careful as you lift the motherboard up because there is one more ribbon cable
underneath for the screen, the LCD and digitizer.
So I’m going to unsnap that just like Lego and that releases the screen from the motherboard.
Here you can see the motherboard.
So the screen you’re going to replace has a unit.
The part that I just took off is the screen.
So if you’ve cracked it, then that’s the part you have to replace.
Here is the charging port.
I’m going to take my little tweezers and slide them underneath.
There’s kind of like this sticky glue stuff holding it on.
It’s pretty tacky so you can always just reuse it if you’re planning on keeping the
same charging port.
And the microphone is also on this same piece.
So when you replace one, you’re replacing both parts.
Usually these are only like 10 bucks.
I’ll put them in the video description below as soon as they become available.
I get all my parts from Amazon usually.
Then as you’re putting it in, make sure it lines up with the grooves and the little
pin here at the bottom.
It’s pretty exact placement.
To remove the headphone jack it’s pretty simple; just pop your tweezers in and the
whole thing pops in and out.
Pretty straight forward.
I’m pretty glad with how Samsung makes their phones.
Everything is pretty fixable.
Then there’s a little metal bracket holding onto the speaker, proximity sensors and front
camera.
So I’m just going to put my razor into there and pop that off which releases the speaker
and the proximity sensors.
So if you’re phone doesn’t turn off when you put it next to your face during a phone
call, this is the part you have to replace.
As well as if you can’t hear the person obviously, you need to replace your earpiece.
And then here’s the front facing camera.
Another super simple easy piece to replace.
And then to put the metal bracket back into place…I’ll give you a better angle on
it here in a second…but just grab the little guy and then there are two little grooves
up at the top that kind of hold the bracket into place, and a pin at the bottom.
You can see the two little grooves right here as I get that back into place.
And then the rear camera is held together by a ribbon cable with a latch.
So I just lifted up the latch, took out the camera, put the camera back in.
Super simple to replace as well.
If your camera has specks or purple splotches, this is how to fix it.
And so the screen as a whole is what I’m connecting to the motherboard again.
So remember if you cracked your screen, you got to replace that whole chunk.
Pulling off the charging port, the cameras, and then putting them on your replacement
screen, and then putting it all back together again.
I’m lining up the ribbon cable with the connection port on the motherboard and snapping
it into place like a Lego.
And then folding it back over onto the phone making sure that all my little ribbon cables
from the ear piece and proximity sensors are on the right side of the motherboard and not
pinched underneath.
Setting that down.
You have to make sure it lines up at the top so it’s flat down with your phone.
You shouldn’t feel it bow underneath your fingers when you press down on it.
Anyway, latch down all of my ribbon cable connectors from the top.
Remember, there is the headphone jack, the speaker, and the camera.
And here’s the charging port connector down here at the bottom; latching that down into
place as well.
And then the back goes on the phone.
I’m a big fan of how Samsung has done these backs recently.
It’s the same with the S4, the Note 3 and the Mega; some of their newer phones.
Once the phone’s been open you really can’t tell.
It snaps back pretty flush with the front screen again as you can see.
And then I’m popping in the back speaker as well.
Just kind of leveraging that into place with my pry tool.
And there’s the screw diagram again.
Popping the battery back into place and if you have any questions make sure to leave
