Samsung S5 Home button

Schritt 1

Verwende ein Öffnungswerkzeug aus Kunststoff, um die Mittelrahmen-Anschlussplatte aus Kunststoff nach oben zu hebeln.
Entferne die Anschlussplatte mit einer Pinzette.
Dort sollte genügend Kleber vorhanden sein, um die Platte beim Wiederzusammenbau wieder festzukleben. Andernfalls verwende etwas doppelseitiges Klebeband.

In my experience I have always removed this Home button protector panel with ONLY a plastic opening tool, and I have never found adhesive beneath it.

Schritt 2

Heble mit der Spudgerspitze den Home Button Kabelstecker gerade aus seiner Fassung.

Schritt 3

Bei den folgenden Schritten wirst du einen iOpener verwenden, um den Kleber, der die Display Einheit am Rest des Gerätes befestigt, zu erwärmen. Dadurch kann das Display sicherer und einfacherer entfernt werden. Wie du den iOpener richtig verwendest, erfährst in der iOpener Anleitung. Beachte die aufgeführten Warnhinweise.
Platziere den erhitzten iOpener für mindestens 90 Sekunden auf der linken Seite des Mobiltelefons.
Wärme den iOpener wieder auf und platziere ihn auf der rechten Hälfte des Gerätes.

good location for a timer, I am taking my phone apart

¿se puede hacer con la pistola de calor?

Diego Alomoto - 02/04/18

Si, puedes utilizar la pistola de calor también, pero ten cuidado ;-)

Otra opción es usar una “placa calefactora” que, según yo, es la opción mas “profesional” ya que con ella se puede limitar la temperatura, para que no se malogre la pantalla táctil (la “digitizador” detŕas del vídrio).

OmniWeb Technical Education - 22/04/18

Another option is to use a “hot plate” which, according to me, is the more “professional” option since with it you can limit the temperature, so that the touchscreen doesn’t get ruined (the “digitizer” behind the glass).

OmniWeb Technical Education - 22/04/18

A hairdryer on low not being used statically is also an easy option. Or if your a caveman or low tech, and all you have is a single baby sock and metal bb’s or little rocks, as long as they’re not silica rocks, put them in the baby sock, at the edge of your cave campfire to warm them and thats all you need. -retired aviation engineer

Schritt 4

In den folgenden Schritten wirst du ein Opening Pick verwenden, um den Kleber, mit dem das Front Panel Glas festgemacht ist, zu lösen. Wenn du auf Widerstand stößt, wende nochmals etwas Hitze, bevor du mit dem Pick weiter in der Spalte entlangfährst.
Führe die Kante eines Opening Picks unterhalb der rechten unteren Ecke des Frontglases ein.

I hope this helps others:

my screen was STRONGLY glued to the midframe, it was impossible to remove it without breaking it, be very careful with the copper adhesive in the midframe!!!

I can't even understand how this guide doesn't mention it properly!

Pedro - 27/11/16

Yeah, the real trick with these types of screens is to measure (or just “have a feel for”) an adequate temperature with the heat pad (e.g. iOpener), or heat gun, or hot plate. First you have to heat up the screen just enough so that you can “break into” one side without breaking the bezel or the glass, and then verrrry carefully and verrrrry gradually insert plastic opening picks (or even playing cards) as you make progress around the exterior border of the phone. Whenever I do this, I always insert 5-6 objects (again, plastic picks or playing cards) before I fully remove the digitizer-glass assembly, which typically ends up as follows as I move around the exterior border: one pick at each of the four corners and one pick on each of the two sides. WARNING: DO NOT INSERT ANY OBJECT BENEATH THE GLASS MORE THAN A FEW MILLIMETRES FROM THE EXTERIOR BORDER.

OmniWeb Technical Education - 22/04/18

Thanks for the info guys! :-)

Champ - 28/06/18

Wow seriously 100% ur going to break the LCD if this is the first time opening the phone this is why android is built disposable it now costs 60$ to fix a stupid 10$ part this fix is definitely not worth it

android=disposable

apple=a better way of life

I will never attempt to fix another android again

Schritt 5

Fahre mit dem Opening Pick entlang der rechten Seite des Displays.

This is not as easy as they make it seem in this guide. The real trick with these types of touchscreens is to properly measure (or just “have a feel for”) an adequate temperature with the heat pad (e.g. iOpener), or heat gun, or hot plate, that you use to heat the adhesive beneath the glass exterior of the digitizer-glass assembly. First you have to heat up the screen just enough so that you can “break into” one side without breaking the bezel or the glass, and then verrrry carefully and verrrrry gradually insert plastic opening picks (or even playing cards) as you make progress around the exterior border of the phone. Whenever I do this, I always insert 5-6 objects (again, plastic picks or playing cards) before I fully remove the digitizer-glass assembly, which typically ends up as follows as I move around the exterior border: one pick at each of the four corners and one pick on each of the two sides. WARNING: DO NOT INSERT ANY OBJECT BENEATH THE GLASS MORE THAN A FEW MILLIMETRES FROM THE EXTERIOR BORDER.

Schritt 6

Fahre mit dem Pick um die Ecke bis zum Lautsprechergitter oben am Gerät.

Be sure not to nick and tear the capacitive touch chip interface that meets the LCD screen here! I caught it and didn't even feel the resistance. :-(

Schritt 7

Der Kleber oben am Mobiltelefon ist nur ein schmaler Streifen über dem Ohrhörer-Lautsprecher. Fahre mit dem Pick oberhalb der Lautsprecher entlang, um eine Beschädigung der internen Komponenten zu vermeiden.
Fahre das Opening Pick entlang der Oberseite des Mobiltelefons und sei dabei vorsichtig, das Pick nicht zu tief einzuführen.

I have been extra careful, and it did not prevent me to sever the flat cable in the upper left corner. The cable is very close and you should take extreme caution.

Neocray - 12/04/16

I accidentally sliced the flex cable and now my Digitizer refuses to work….LCD is still functional.

Take heed lol. I found out the hard

Blank - 20/01/20

Schritt 8

Fahre mit den Pick um die obere linke Ecke herum.
Wenn der Kleber abkühlt und du deshalb auf Widerstand stößt, wende erneut einen erhitzten iOpener auf der linken Seite des Gerätes an.

Schritt 9

Fahre das Opening Pick entlang der linken Hälfte des Mobiltelefons und stoppe an der unteren linken Ecke.

Schritt 10

Fahre mit dem Pick entlang bis zur linken unteren Ecke des Mobiltelefons und gehe sicher, dass es richtig platziert ist.
Im folgenden Schritt wirst du den iOpener über der Home Button Seite des Mobiltelefons platzieren. Pass auf, dass du mit dem Opening Pick nicht abrutscht.

Schritt 11

Platziere den wiedererhitzten iOpener über dem unteren Teil der Display Einheit.
Es befinden sich empfindliche Komponente in diesem Teil des Mobiltelefons. Deshalb ist es besonders wichtig, dass der Kleber erwärmt und leicht zu lösen ist, um das Gerät zu schützen.

Schritt 12

Das untere Ende des Gerätes enthält die Flachbandkabel von Soft Button und Home Button. Wenn du das Opening Pick zu tief einführst, riskierst du diese Kabel durchzuschneiden.
Fahre mit dem äußersten Ende von einem Opening Pick entlang der unteren Kante des Displays, um den letzten verbleibenden Kleber zu lösen.

How do I avoid damage? I tried this and now have to get a new screen, LED, and digitizer since the grey part under the glass snapped and cracked in many areas. I had to discard it and order a replacement to fix the phone.

cbressijr - 26/07/19

Schritt 13

Drehe das Opening Pick etwas, damit sich das Glas vom Mobiltelefon löst.
Falls das Front Panel sich nicht leicht lösen lässt, sitzt der Kleber noch zu fest und muss weiter durchgetrennt werden.

Be aware that there is adhesive on the inner parts of the screen. Plan on replacing this screen and digitizer as well.

AB Computer Services - 15/11/17

Schritt 14

Wenn sich das Front Panel nicht leicht ablösen lässt, muss möglicherweise der Kleber auf dem Soft Button Kabel gelöst werden.
Diese Kabel sind dünn und können leicht beschädigt werden. Gehe deshalb sicher, dass du sie nur von der Display Einheit entfernst, aber nicht zerpflückst.
Führe ein Opening Pick unter die Soft Button Icons auf dem Display ein und heble die Button Kabel auf der Innenseite des Front Panels ab.

Accidentally cut one of the side buttons. It wouldn't come out, the screen was badly cracked.

Nickoakz - 18/01/16

My digitizer was glued to the chasis, the glass came up separately and the digitizer broke when I tried to pry it up.

ken - 25/02/17

That’s actually probably because you might not have heated the sides of the screen (where the adhesive is located) enough before prying up on the exterior border of the glass part. It’s very difficult to know the tolerance limits of such devices if you’ve never seen them apart before, and as such one can easily get confused between where the glass ends and the digitizer begins. On my first smartphone repair I broke a digitizer, so I know how it feels.

OmniWeb Technical Education - 22/04/18

Schritt 15

Hebe die Home Button Seite der Display Einheit etwas an, aber entferne sie nicht.
Entferne das Front Panel nicht vollständig. Es ist immer noch durch einen Stecker verbunden.
Falls du ein Home Button Flexkabel wiederverwendest, sei vorsichtig, dass du das Kabel nicht vom Home Button trennst. Durch den Kleber kann das Kabel vom Home Button abreißen. Der Home Button würde in diesem Fall noch funktionieren, der Fingerabdruckscanner jedoch nicht.

The display assembly I purchased from ifixit.com included a new home button with a new flex cable. If you have the same, I'd recommend removing the home button in this step.

pdub01 - 08/01/15

Same here. My home-button flex cable extended under the main board rear cover plate, and would have required removing screws to extract. So I left the original home button installed, and removed the one that came with the new assembly.

The ‘reverse order’ step are misleading. It is not trivial to reconnect the main screen flex cable to the main assembly — lots of trial and error to get it snugly plugged into the receiving connector. That part is glossed over. (Dissassembly is trivial. Reassembly is hard.)

After putting the screen and connectors on, I learned that there’s some plastic edging on the BACK. I had to remove the screen since it effectively wraps the home-button key. The new screen cracked. Great.

Peter Nicoll - 09/01/21

Sansumg S5 is the stupiest design (for repair) ever.

I have fixed s2,s3,s4, note, note 2 and note 3

All of them, you can get into the logic board from the back without touching the screen assembly.

With the S5, just a simple problem could cost you buying a new lcd assembly.

You must remove the lcd in order to remove the screws for the logic board cover.

I purchased a cracked lcd S5, so I can replace it and sell it. My mistake was I did not did a research on the tear down (thinking it should the same as previous S model.

To make story short, lucky for me, I did a dry test of the entire phone, before glueing on the new lcd assembly.

Because the front camera lens was damaged, cost $5.

If I glued the lcd, it would be 50/50 chance that I would crack the new screen.

So any repair that you need to do on the S5, you will have to consider the risk of breaking the LCD.

I hope Samsung change the design on the S6. Which I doubt it. Because the higher cost of repair means people won't fix them = more new sells

idevice Recycle - 21/02/15

How can I find out if I messed my phone up . the person who glued the screen on didn't glue it on right , so I tried to take off the screen and I got it off but now that I try to put it back on the screen is black .

cholitaesh21 - 27/01/16

I know this reply is a bit late, over 2 years late, but I just wanted to add to idevice Recycle that the way "they" designed this phone is exactly as you described, to make it wayyyy more difficult to fix even the most simplest thing on this phone. Inverting the motherboard, designed exactly the opposite way of the S4 (as you described), from their standpoint of view, as you'd have to admit, was a brilliant idea on "they're" part.

I've torn apart and fixed many cell/smart phones in my days thus far, but mostly iphones by far. A friend passed

me one of these phones this past week. I've never messed with one before so you already know, even though I

have much knowledge about them, this site was the first I visited about this phone. Needless to say, go figure.

They did a really great job though making this phone one of the most difficult phones to do any type of repair

on. Adhesive sucks. But eh, all is well with a bit of time and patience. Had to replace rear camera and middle

bezel frame. Time to off it....

you_mad.lil_fella - 21/04/17

This guide may have been written for a different revision but the SM-G900F that I just repaired had glue sticking the entire of the rear of the screen to the chassis making it very difficult to remove. Had to use a spudger and push it down the inside of the phone separating the copper film from the chassis to free it up. Would be easy to damage the home button cable but I was ok.

Adam - 23/02/15

I had the same thing happen just now. I was working on a G900A. A real PITA!

mcr4u2 - 16/05/16

Is there a need to put adhesive after removing the screen?? If so, do you have an adhesive recommended...

garrykufa2000 - 13/04/15

Should be. i recommend using 3m strip double sided adhesive

leiki42 - 31/01/16

I had the same issue as idevice recycle. The model S5 that I was working on had a huge amount of glue on the back of the lcd which I wasn't aware of - this caused me to crack the glass which then literally broke the lcd in half (costing me £120 for a new screen!!!)

I've repaired all manner of Samsung products over the years and I've never had any issues with any model apart from this one. My advice to anyone doing this repair is once you have managed to unstick the screen from the frame, before attempting to remove it, apply a bit of heat (but not too much, you don't want to damage anything) to the back of the phone where the battery normally sits. This is where all the glue on the back of the lcd is located which sticks the lcd to the frame of the phone - I wish I knew of this before trying to remove the screen!

Clems - 29/10/16

The guide needs to mention that the LCD is firmly glued.. Mine was bust anyway, but Step 19 is not fit for purpose.

Dave - 23/02/17

So this really blows. I needed to swap the logic board from a phone with a cracked screen to one with a good screen. Yeah that’s not happening. I now have two cracked screens… Thanks Samsung! The difficulty on this should be way higher. As others have said, the screen is glued on the underside over a large portion where the copper foil is. It’s not coming up easily or in one piece.

Jeremy Buseman - 04/12/17

If you want to make the reassembly easier, be careful to not separate the Home button assembly, from the glass. Instead, just carefully pry away the soft button adhesive connectors.

OmniWeb Technical Education - 22/04/18

Schritt 16

Hebe den Kabelstecker der Front Panel Einheit mit der Spudgerspitze aus seinem Anschluss auf dem Logic Board.
Entferne die Front Panel Einheit vom Mobiltelefon.
Wenn das Ersatzdisplay ohne einen Home Button geliefert wurde, dann folge unserer Anleitung für die Home Button Einheit, um deinen alten Home Button auf das neue Display zu übertragen, oder um einen neuen Home Button einzubauen.

Absolutely wonderful! Worked like a charm. This is the easiest replacement I have seen so far on an Android. :)

Paul Frutiger - 01/03/18

This was all a breeze until I removed the screen and the LCD and digitizer crumpled on me now I have to replace the whole thing not just the charge port which was the initial issue… Great guide though and thanks it helped. Minus the panic attacked when all the parts started to crack and break as I removed the glass and now digitizer or LCD stayed safe for replacement.

cbressijr - 26/07/19

Be VERY careful of the flex ribbon on the LCD …it'll break with the slightest twitch…one of mine ripped totally in half

Blank - 20/01/20

please i need number lcd samsunggalaxy s 5 it is g 900 a or what?

fady awad - 15/01/21

The difficulty of changing the S5's display is enormous. Not only is it glued around the edges, it's also glued strongly to the midframe. If you ignore this, damage is inevitable. The digitizer flex cable is also very easy to kill. Glue sucks. When assembling the display, the edge bonding is not enough; you need special double-sided adhesive tape that is stuck to the midframe so that the display does not fall out again so quickly. Before doing this, you have to thoroughly remove the old adhesive on the edge. I have successfully performed this procedure once but would never do it again.

Good guide, but how to apply new adhesive for the lcd display on the midframe ?

Arnoud - 16/03/17

It should already be attached to the LCD, if not then you can purchase the adhesive and attach it to the LCD yourself

Patrick Lee - 17/03/17

I would like to know whether there is a pin-compatible home button to replace the original Galaxy S5 home button to _physically_ get rid of the fingerprint reader unit and solely keep it as a simple and dumb home button.

Thanks in advance.

E.Remarque - 19/04/17

It should be noted that unlike replacing an iPhone Home Button, you can reprogram a replacement Galaxy Fingerprint scanner.
