简介

Replace a torn, damaged or faulty fingerprint reader in your Galaxy S5 phone.

  1. Use a plastic opening tool to pry up the plastic midframe connector panel. Remove the connector panel with a pair of tweezers. There should be enough adhesive to readhere the panel upon reassembly, otherwise use a small amount of double-stick tape.

    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.

    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).

    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).

    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

  4. In the following steps you will be using an opening pick to separate the adhesive securing the front panel glass. Only pry where directed.

    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!

    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.

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

    ken - 回复

    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.

  15. Slightly lift, but do not remove, the home button end of display assembly. Do not remove the front panel entirely. It is still attached by a connector.
    • Slightly lift, but do not remove, the home button end of display assembly.

    • Do not remove the front panel entirely. It is still attached by a connector.

    • If you are reusing the home button flex cable, be careful not to sever the cable from the home button. Adhesive can cause the cable to rip apart from the home button. While the home button will still work, the fingerprint scanner will not.

    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 - 回复

    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.

    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

    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 -

    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....

    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.

    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!

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

    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.

    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.
