Samsung Galaxy Note 4 Display Assembly Replacement

Difficulty

Moderate

Steps

7

Time Required

15 - 30 minutes

Introduction

Use this guide to replace the display assembly on your Galaxy Note 4.

  1. 3VLLLHmrBPQpBOE3

    • NOTE: It is suggested to remove the battery, S Pen, SD Card, and SIM card (if your phone uses a SIM card).

    • Begin by heating the edges of the screen. The adhesive on the Galaxy Note 4 is weaker than on newer generations and will release easier, requiring less heat and prying.

  2. MBMBBqlQa6UneQVw

    • Slowly work your way around the edges of the screen with a pry tool or pick.

    • Work your way around the top and sides of the device, and very carefully approach the adhesive on the bottom of the phone. The Galaxy Note 4's touch-sensitive pads lay in the way of your opening picks and it is very easy to sever them.

    IMPORTANT NOTICE: Be VERY careful not to damage the softkey flex's!

    droopie -

    Each softkey is a tiny little board (~3x5mm) with a ribbon cable that goes to the screen edge and then around the back of the midframe.

    These are glued to both the screen and the midframe, so when prying the screen away with your spudger they may stick to the screen, stretching the ribbon cable across the gap allowing you to tear / cut it.

    Minimise this risk by only entering your spudger from the bottom edge of the screen (not the sides) so that if you touch the ribbon cable, it will likely peel the board off the underside of the screen.

    (I found out the hard way. Suggest installing "Back Button (No Root)" as an on-screen alternative)

    Robert Meerman -

    Even with this warning, I still cleanly cut the menu button on the left off.

    • Insert the Jimmy underneath the LCD to cut the adhesive in the middle part. The adhesive is strong so make sure you are underneath the copper insulation before separating.

    This is the hardest part of the removal process; unlike the person responsible for the actual parts shown in photos, I was able to do it without ripping the copper portion; however, I managed to separate a little part of the very edge of the copper and now i’m not sure if the screen is still going to work or not. So when you get to step 3 when first inserting the cutting tool make sure you are in between the copper and the midplate. This is where I feel ifixit could have done a better job to explain how to exactly get in between the midplate and adhesive and not the screen and determine so.

    • Notice 1: The adhesive is in the red line.

    • Notice 2: If you insert the spudger from right side, keep the length of the tool in less than 2.2cm, which is for avoiding damaging the home button flex.

    • Notice 3: If you insert the spudger from left side, keep the length of the tool in less than 4.4cm for the same reason.

    • Notice 4: Pay attention to the part with LCD screen flex. When you cut the adhesive, leave the top part alone to avoid damage the flex. But if it's the broken screen, you don't need to worry so much.

    • Be careful with the bottom side because there are the soft keys.

    • If the adhesive in the red line don't function any more when you place the new LCD screen, you can choose to use the 3M double side tape. It can help to fasten the new screen together with the LCD screen sticker.

    Please change font color to Red for below points as you did in other guide, I messed up soft key flex

    Notice 5: Be careful with the bottom side because there are the soft keys.

    Notice 6: If the adhesive in the red line don't function any more when you place the new LCD screen, you can choose to use the 3M double side tape. It can help to fasten the new screen together with the LCD screen sticker.

    Is there a way to get the LCD off with the copper still intact?

    • Release S Pen touch sensor film connector and LCD screen connector.

  7. Of5Mp3LTMShi2VU4

    • Separate the LCD screen from the frame of the device.

    What is the purpose of the brown paper on back of the screen… my screen is not working and the paper is torn

Can I use a hair dryer instead of a heat gun

charlie -

Yes, a hair dryer on the hot setting will work in place of a heat gun for this repair. You may have to heat it a bit longer but you will be able to tell when the adhesive is warm enough, as it will begin to separate a lot easier.

Brad -

Here in our tech community we have been discussing the foil under the LCD. We are doing more testing but there might be a connection with the foil functioning in conjunction with S-Pen and AirView. Can anyone confirm this?

Kevin Henson -

Yes, the foil permits the s pen to function. If you have the part of the foil that was riped off you can tape it back.

Gianrene Padilla -

the foil itself has nothing to do with the functioning of the spen. It is for heat dissipation

Mentat Solutions -

Read somewhere the copper acts as the digitizer for the S-pen.

Has anyone had any success swapping out the glass on the display?

Need help with step 4

I opened the screen and attached the new screen to the connections and thanks to you, it is working.

While I was in the process of opening the assembly I took off the adhesive on the mid frame. i.e Step 4 pic, in the red line.

I am trying to find the replacement for it. I would really appreciate if you could help me out.

Rohit -

Hoello do you know a web site for buy the display for note 4?

Edmundo -

Hello do you know a web site for buy just the display for note 4?

Edmundo -

Hi i think I may have damaged the cable to the back button . It lights up but doesnt respond to my pressing it. Im getting by by using the onscreen shortcuts for the buttons. Is there a spare part to replace these buttons?

William Nunez -

Permisi mau tanya neh... aq kan baru beli note 4 bekas ori samsung bukan replika tapi anehnya kenapa di dasar layar lcd nampak tulisan " pent mouse inspired by humans creating the future " apa lcdnya bukan ORI ya...?thanks infonya...

Zaky hamed -

The first day I got my note 4 I dropped it once and Screen Cracked. I have watched every single YouTube video on this subject, and Have found this example best. Luckily my phone works perfect just need to replace the glass. I am going to do the repair seeing as I don't have insurance etc. Is the card Method a good idea to pry glass away? I just want to do it to where I'm causing the least amount of stress on lcd/ Digitizer. Also any good advice anyone has that would have really saved your ass duringduring your own repair would be greatly appreciated. Thank you and wish me luck! Oh yah also I only have a hair dryer. While using this I'm assuming it's going to require more heat then ie heat gun this is made for this sort of stuff. Thank you all!

Andre mills -

can i take lcd from working note 4 and replace it on broken lcd note 4 ? Original new lcd is very expensive and I am getting deal on second hand Note 4 online.

cool9fox -

Can I pull lcd from an old working Note 4 and replace it to my new lcd broken Note 4 ?

cool9fox -

Does ot comewith the adhesive?

mmarcucci -

Sorry, it doesn't include lcd screen sticker, but you can but it separately here: http://www.witrigs.com/oem-lcd-with-digi...

Witrigs -

Does it come with the adhesive??

mmarcucci -

If the lcd assembly is not attached will the phone still power on or does the lcd have to be attached to the phone before the power button will boot the phone up?

Alex Grison -

you can use the hair dryer its ok, there's no need to specify how long does it take for the glue inside the phone to be warm enough since this is about practice, and if you are patience enough, you'll be able to being testing carefully, how the adhesive is ridding off, at the end you will know an estimated time on how long it takes to be completely off.

Moises Mazier -

I accidentally cut off the home button flexi cable and the touch screen not working after assembly. Any relation between them?

Marc -

Do i need to put adhesive below the lcd?i mean i have just the pre-cut adhesive which i put on the sides of the lcd so that it glue to the midframe panel

arvkajunion -

Can I get the kit to rebuild my own digitlizer screens

Raymond Barberio -

my note 4 screen is responding only to the fingers. but not to the s pen plz help me please respond to mr.dony007@gmail.com

Dony Biju -

I'm not 100% sure, but the copper foil on the back of the LCD may need to be intact for the s pen to work.

Todd Aucoin -

Hi, maybe you’d be able to help me but i have litteraly the opposite of your problem. My phone’s top part of the display is the only part of the display yhat’s responding to my finger while the entire screen responds to the s-pen. Any help is welcome and hopefully i’ll get sn answer from you….. Greetings from Suriname..

Fifi Thompson -

how can i re-install ind affixed the new screen with the Adhesive

Mohamed Hassanien -

Yes its repairable as I believe Z- axis tape and a foil patch may work. I have done this on two phones so far and they both worked as it was just a ground in these cases.

Andre -

hey I hv a note 4 that the lcd flex Is broken how am I gone repair it

davis -

How much is the screen in Ghana CEDI's?

Dj Noble gh -

My nephew dropped my Samsung galaxy note 4 he now black screen me blue pulse light blinks…tried every method but nothing … help me out plz

attaabbas01 -

If its black, chances are the screen is kaput. About the only way to check is to disconnect the flex for screen, if this is the problem phone should then boot up fine. I saw this on some S6’s once so its quite a common problem.

@pyractor

Andre -

Note, for folks with damaged foil(s) a suitable replacement is that copper tape sold for deterring slugs.

If you’re careful its possible to overlap it and reattach with 3M Z axis tape.

I did this on an old Huawei with similar problem and it worked fine, also handy for reattaching broken screen flex but its a *lot* harder.

If you have a good glass with bad flex (how?) then this sometimes does work.

Re. dodgy touch screen it can’t be replaced as part of the assembly but can sometimes be worth checking that the secondary flex hasn’t come unplugged from the board: its a PITA to check but if you get it out try cleaning with IPA in case of fingerprints.

Andre -

Does the replacement screen come with a pen foil.

fr4nkyst13n -

Can the glass be separated from the digitizer?

Smeargle -

It can be but it's way easier to get the whole digitizer assembly

Carolina Fisher -

HELLO.CAN ANYONE HELP ME…I DROPPED MY SAMSUNG GALAXY NOTE 4AND I SEE THERE IS A VERY TINY BROKEN ON THE LCD TO IT . THERE IS LIGHT BUT IT’S NOT TURNING ON,AND THE WHOLE SCREEN IS BLACK sorry im not trying to yell we’re just desperate,,please help!

ta.chu -

I did this today with a hair dryer and cut up gift cards lol. The back and recent buttons are glued to the glass so be sure to unstick them before lifting too far so you don't rip them out. I had to reseat the screen ribbon cable, not replace the screen, so I just laid the screen back down where it goes and heated it again to reactivate the adhesive. It's sticking like new, no issues there. Ripped a bit of the copper foil off but the s pen still works 100%, touch and hover.

Carolina Fisher -

I need to change my Note 4 as the touch is getting progressively more temperamental. I did look into regenerating OLED panelswith screen burn using recent discovery of molecule sensitivity in 593 and 1064nm (IR) direct laser scanning when in “black” mode *#0*# but the problem here is that you need the board connected for it to work and it takes weeks.

Intriguingly this also helps explain how the compensation cycles work on newer phones/TVs and why negative images sometimes appear for a while then go away as its the controller averaging out over many many frames.

testingh -

Is the digitizer actually part of the OLED? Looking at this one if you can see the spudger between the glass, display is already toast.

I did try to test it but any sign of cracking on these is generally terminal in about 12 hours unless you are incredibly quick at sealing it.

Actually did test this and display initially worked but not the day after.

There’s an argument not to use the very thin spudger for exactly this reason!!

Andre De Guerin -

Ich sehe überall in Anleitungen die defekte Kupferfolie. Hat diese keinen Zweck?

Darunter scheint eine art Graphit-Belag zu sein. Warum wird die Kupferfolie nicht ersetzt?

Die Kupferfolie scheint keinen echten Zweck der Befestigung zu erfüllen. Sonst müsste die Kupferfolie fest mit der Displayrückseite verbunden sein. Ich erkenne keinen Nutzen im Klebe-"M".

Ich habe die abgerissenen Teile vom Kleber-"M" entfernt, und es (mit feinen Lücken) wieder mit Klebeband im "Loch" befestigt. Nun knistert es etwas, wenn ich auf den noch nicht neu fest geklebten Bildschirm drücke.

Tobias Claren -

I see the broken copper foil everywhere (in tutorials). Does this have no purpose?

Below it seems to be a kind of graphite coating.

Why is not the copper foil replaced?

The copper foil does not appear to fulfill a true purpose of attachment. Otherwise, the copper foil would have to be firmly connected to the back of the display. I do not recognize any benefit in the adhesive "M".

I have removed the demolished parts from the adhesive "M", and fixed it (with fine gaps) again with tape in the "hole". Now it crackles something when I press on the not yet newly glued screen.

Tobias Claren -

Hi,

step 7, the broken film how to restore it? can use an alluminium tape?

Many thanks
