[Completed] Galaxy A3 Digitizer split - XDA Assist

Hi guys, yesterday I tried to split my broken glass from the lcd and I succeded with it. After this there was an uv loca gel left over the lcd and I used acetone to remove it.
But the problem is that also at the back of the LCD there was specific tape I think white scotch and black but unsure and she also fell off.
I tried to check if the display is still working and it's working. Just wondered about that tape or adhesive I don't know what is it and, is it so important to install a new one, before apply a new uv loca gel over the lcd.
The tape was between LCD and Copper, directly at the back of the lcd when used acetone it was sticky but removable, so I pull all of it, but display still works.
Thanks in advance,
Sorry for my bad English.
updates:
When I get the display from the frame, the copper left on the frame, perhaps biggest mistake?.
Maybe it could be the tape between the copper and LCD.
I just know that it's at the back side of the LCD without the copper.

Best way to stick the digitizer bach to the screen

So it's all about a Sensation with a defective digitizer. There are countless videos, DIYs, forums posts and blog articles on how to take the phone apart and to separate the digitizer form the screen. However, there is nothing on how to glue the new digitizer back in place. The options I've seen so far are:
1. Use 3M 2mm tape
2. Use what's left of the original glue (reheat and try to make it adhere to the new digitizer)
3. Use super glue
I live in Germany and it turns out that it's almost impossible to find 3M 2mm tape out here. So, could I just use any available type of double-sided tape and just cut it in 2mm stripes? What's the thickness of this 3M tape (need to know so that I can find a proper alternative).
However, the bigger question is, which of the three options mentioned above is the best? I guess that trying to make it work with the old adhesive leftovers is the worst thing to do, but is 3M (or equivalent) tape better than super glue? I mean, it's important that no dust comes through between the digitizer glass and the lcd screen... and that the newly fitted digitizer withstands the influence of high and low temperatures (hot sun in the summer, cold ice in the winter).
So, what would you say is best? I've never done this before, so I guess you have much more experience than I do...
Thanks

Its not quite the same but I had this problem when replacing a LCD screen on a nintendo ds lite (bottom touch screen). I just went with the double sided sticky tape as I felt I could be far more accurate with it compared to super glue. I just cut it into the sizes I needed with a sharp knife and fitted it to the digitizer And then to the LCD. I have had no issues with it so far, its not slid or anything but then again it is housed in casing... if I was you I would try the tape first and if it seems unreliable try for the glue, just make sure you don't miss as it will muck up the digitizer if its no placed right I believe.
Good luck
Tapped out from my sexy nexus 7
I'd also say that the double sided sticky tape is probably the best thing to try out.. However, I'd like to know how thick the tape is. It should be thick enough to make the glas digitizer stick and also as thin as possible so that the new screen isn't appear to be higher than the old one...

glue for screen ?

Hello,
After changing the screen of my moto G, the new one is no longer stuck and is moving.... I had to remove the original glue (tape?) with an hair dryer.
My question is : with what I then paste the screen?
thanks a lot

This is a very annoying problem of the chinese displays that come with a frame or pre-applied tape.
The display+lcd assembly is too heavy to be held by any normal 2-sided tape (3M 300LSE for example).
After hours of checking how the original thing was made it turned out that it has a rubber-like gasket that is glued to the frame, which acts as bonding surface for the 2nd glue used to hold the digitizer to the frame.
These are all my own findings, sadly no pne is discussing this problem anywhere or at least I didn't find any.
I've used a transparent epoxy (65-70% resin ~30-35% oxidizer so the compound hardens slower).Use a wooden tooth pick to apply the glue on the frame, don't put to much of it, just a hair-thin line.
Put the screen on and press it well and be ready to clean off any glue that may come out of the edges. The epoxy is easy to clean until it's set, use isopropyl alcohol 99% or some dry contact cleaner with a cotton cloth or kitchen paper.
The drawback of using epoxy is once it's set, you won't be able to remove the screen from the frame by any viable means.This is not a problem tho, since you can buy the whole assembly, should you need to replace the screen again.
Good luck.
:good:
Thanks a lot for your tip.
I'm gonna look for epoxy and try to do as well as you
Thank a lot once more
same issue
Hi,
Thank you very much for having shared your experience with us .
I have exactly the same issue with my Moto G and I've finally found a way out thanks to you. I would try this but I'm afraid of doing it bad. Should I apply the glue exactly in the border of the display? Do you happen to have any video showing it in detail?
Have a nice day

Hello,
You should apply the glue in the frame, as close as possible to the outer rim and spread it as much as possible on the thin inner lining where the plastic of the frame and the glass make contact.
You can also use universal transparent glue, like JIP or Henkel... etc.These glues are a bit more liquidish and it takes more time to set properly, but they are also more flexible and you can also remove the display with heat, should you have the need to .
Sorry no videos available on this, but with a little effort and reading you'll be fine.
liveroy's advice is great. I've followed it with success, although the screen I bought has the dreaded phantom touch issue (cheap ebay job!) and will have to go back (this issue was apparent even before I glued it to the mid-frame).
Firstly I separated the screen from the mid-frame with two small suction cups, designed for removing halogen light bulbs, on the top and bottom of the glass. This worked well, but I had to use very gentle tugs to ensure I didn't tear the ribbon cable. Because the double-sided tape used was already separating, this was quite an easy part of the job.
I used Araldite 2-Tubes Standard Epoxy, because it has a very long cure time, which allowed me to work slowly. With the screen and mid-frame completely separate and cleaned up, I then threaded the screen's ribbon cable through the hole before glueing. The trickiest bit was putting the epoxy along the frame where the ribbon cable is; to do this I just wedged some folded paper between frame and screen while I layed down the epoxy. I guess I could have just done this bit first and avoided the need for a paper wedge (this was used to prevent prematurely sticking the screen to the frame before all the epoxy's down).
I used the screen's plastic film to protect the screen from the epoxy, and cleaned the excess epoxy with an old bottle of disk head cleaner I found lying about (smelt very alcoholly!) and cotton buds. I used some clothes pegs to clamp the screen to the frame, but I took them off after a few hours. Then I left it for a couple of days. The result was as good as I could have hoped for. I can see a little bit of the dried epoxy in the very narrow trenches between the mid-frame and glass, but this doesn't bother me. Way better than having light streaming through the sides, and it seems like a really solid grip! When in use and getting warm I could still see a bit of lift at the sides, but because it was glued there was absolutely no gap.
Going back to the original need for this fix -
On my phone I believe this is due to a warped, concave logic board, effectively peeling the glass away from the mid-frame when fitted. If it were totally flat then I doubt this would happen. I guess the aftermarket screen manufacturers didn't factor this in when they decided to use "weak" double-sided tape. I've also noticed that, with the new screen in place, the outer back shell of the phone, that you put on last, doesn't quite fit at the bottom like with the old screen - there is now a small a gap where the inner plastic housing is exposed. I think this is because the new mid-frame is straighter than the old, and the old shell has itself bent over time.
Hi,
I'm happy to found this thread. It's the second screen i replace on my Motorola Moto G4 Plus because of this; you can view my comment here : https://www.witrigs.com/oem-lcd-screen-assembly-for-motorola-moto-g4-plus-black#customer-reviews
I will try to use super glue on the top of my screen, hope it'll work. EDIT 20190122 : it worked (be careful to not add too much glue like i did : it was covering camera when pressing !)
Thanks

[Q] Digitizer replacement - glue replacement?

Hi all, I got an i9300, it has the digitizer broken and I need to replace it.
The problem is, here, in Venezuela, the UV glue and the UV lamps are too much expensive... due a pathetic government.
Anyways I need to fix the phone, and for that, I need to replace the digitizer but without the UV glue and UV lamps...
I know there is the double-sided tape but it leave a space between LCD and digitizer, so I don't like it, and... the tape is too expensive also.
I'm trying to find a cheap glue replacement, but I don't know if what I've found untill now would work or destroy my LCD...
So far, I've found a transparent glue, which has the following components:
1) Polyvinyl acetate.
2) Alcohols.
3) Special solvents.
It also says that it has no water.
The thing is that I don't know if this glue would be too abrasive with the LCD and may damage it in some way.
AFAIK, the LCDs has polyvinyl acetate on its components... but as I said, I don't know how this would react with the glue...
Somebody here can give me a hint? should I try it?...
When the glue I've found gets dry, just gets cristallized and over 60ºC it can be easyly removed.
I wouldnt mess with and unknown glue or adhesive that is not meant for this type o job. I would seriously recommend considering the double sided tape. Its a perfect fit and works perfectly.

I see, well finally, I've ruined the digitizer behind the pieces of glass... and the LCD with it, so, I must buy a new whole screen.
Warning: Do the replacement with extremely patience... do not pass the 200ºC and be extremely carefully.

Screen Glass Replacement

Did anybody try replacing the glass screen on the LG G5? Not the whole digitizer, screen only.
Looks like replacement glass is found quite cheap.
http://www.ebay.com/itm/OEM-Front-O...eplacement-For-LG-G5-H820-VS987-/222227276105
There is a crack on my screen, the touchscreen is perfect. Is there a procedure somewhere that can be followed to get it done? I see a lot of videos for a complete teardown. But is it possible to just use a heatgun to take the glass off and put the new one in?
These display modules are oftenly replaced altoghether, because replacing only the glass requires it to be really precisely fitted and hermetically glued, you can probably try to seperate the digitizer from the display, but you may end up with a some dust underneath the glass or some unwanted gaps.

I had a crack on my screen at the top of when it fell down on concrete floor. I had to buy the whole display with glass and digitizer for about 130 euros. I did not know that you can just buy the glass and replace it with a lower price. Oh well... but if you want to separate the glass from the digitizer or anything what is glued, always use the heatgun. You can also use the hairdryer. I had to replace a battery by opening up a back cover with a hair dryer. For separating the glass from the digitizer you have to heat it up very often, pry it open and hold at several spots, to avoid breaking components. It s quite difficult but take it slowly.

So, if I crack my screen I need to get a screen replacement with frame or just screen replacement?

Screen Replacement
https://www.fixez.com/store/lg/lg-g5/lg-g5-display-assembly-lcd-and-digitizer
You can get without the frame, you will just need to heat up the glue between the frame and old screen to cut through the glue to remove the frame. They cover it on the instruction video on Fixez.

[Completed] Galaxy A3 Digitizer Replacement problem?

Hi guys, yesterday I tried to split my broken glass from the lcd and I succeded with it. After this there was an uv loca gel left over the lcd and I used acetone to remove it.
But the problem is that also at the back of the LCD there was specific tape I think white scotch and black but unsure and she also fell off.
I tried to check if the display is still working and it's working. Just wondered about that tape or adhesive I don't know what is it and, is it so important to install a new one, before apply a new uv loca gel over the lcd.
The tape was between LCD and Copper, directly at the back of the lcd when used acetone it was sticky but removable, so I pull all of it, but display still works.
Thanks in advance,
Sorry for my bad English.
