In this video I’m going to show you howto take apart and fix a couple things on the LG G4, one of LG’s newest smart phones comingout in 2015.
This one has the leather back with the center stitching.
Go ahead and turnoff the phone first.
Remove the back cover.
Pop out the battery.
And then you’re leftwith 11 screws to take off from the back housing.
And then I found that it’s easier to grabalong the center of the battery hole and the edge of the phone to start pulling away thatback plastic plate.
You can just unsnap it from the edge of the phone and the whole thingwill just come lose once all those screws are out.
Pretty straight forward.
This phoneis actually pretty darn easy to take apart; nothing is glued down or adhesived like theGalaxy S6.
You can see these little gold contact pads that just kind of rest on top of themotherboard.
That’s how the power buttons and volume buttons communicate with the motherboard.
The bottom part of the bracket also snaps off.
This is how you replace the loud speaker.
You can see the loud speaker segment in this bottom section and the gold contact placethat just sit on top of the motherboard.
LG’s a big fan of those; they always have been.
Here is the buttons, the volume buttons and the camera lens.
Pretty straight forward andeasy to replace.
If your camera lens gets scratched or broken it’s pretty easy topop out and pop in a new one which is nice considering that the camera lens is easy toscratch.
Here are the buttons ribbon cables.
You can just pop those out and replace themwith a new one if needed.
The ribbon cable for the screen just snaps up like a littleLego piece off of the main board.
Be careful with any connections or chips down aroundon the main board, you don’t want to pry up on those when you’re lifting up on theribbon cable connections.
The motherboard just pulls away from the plastic frame ofthe screen.
And you can see here the contact points I was talking about earlier.
Here’sthe SIM card slot (that is not replaceable), battery connections, and the charging port(not replaceable either).
You can see the back here as well.
You might be able to doit if you had some micro soldering tools but that’s beyond the scope of a normal person’scapabilities so we’re going to skip over that.
Here is the front facing camera andthe vibrator motor which is pretty small in my opinion.
Usually with phones and even watchesthey are a lot bigger than that.
Here is the rear facing camera.
Capableof recording in 4K.
It also has the image stabilization chips that you can see on theside of it.
Here is the earpiece.
I’m going to lift off the little ribbon cable first;it has some more of those contact points we were talking about earlier.
And somethingelse I found interesting is there are these little contact points on the side of the motherboardthat just clip in next to the headphone jack.
And that’s how the headphone jack communicateswith the motherboard.
So here’s the screen.
It’s a combination of the glass, digitizer,LCD and plastic frame.
If you are going to replace the screen you have two options: oneis to just buy the glass and LCD combo, or buy it with the frame, which usually endsup costing 10 or 15 more dollars but will save you hours of work and frustration.
Soif you’re going to do a screen repair make sure you buy the screen with the frame included.
You will thank me later.
Put back in all the components.
Got the vibrator motor, the rearcamera, the front facing camera and ear piece all placed back in; making sure that it linesup with the little pins on the side.
And then when you’re placing the motherboard backinto place make sure you lift up the ribbon cables of the cameras so they don’t getcaught underneath the motherboard.
There’s only three to worry about so it’s not toobad.
And make sure the motherboard slips inside of the plastic clasps at the top and the bottom.
Just kind of press it in.
You’ll hear it click into place to make sure that the motherboardis secure.
Putting the button back together.
I put the center button down first, just kindof eye balling it, and then the top layer just clips down over the top of it.
And thenpress it a couple times to make sure that everything’s clicking and you don’t haveanything stuck underneath there and it’s all cleaned out.
And try not to touch theinside of the camera lens either if you go to replace that.
That will make it so thatyour pictures are blurry later on.
I’m going to clip the back frame back together.
Theloud speaker is connecting to the rest of the device.
Making sure that the ribbon cablefor the screen is clamped down to the motherboard.
It’s kind of like a little tiny tiny Legopiece.
It has a bunch of little fins that just clamp down onto the motherboard.
So youhave to line it up perfectly and then just clip it down.
And you’ll feel it snap underneathyour fingers as it clicks into place.
Getting the back housing pressed into the frame ofthe screen.
Getting the battery back in there.
And then I’m going to test it before I putthe screws back in.
Now the back cover’s in place.
I’m going to go ahead and givethe phone a try…and everything works.
