Adhesive/glue for a digitzer/touch screen replacement

Long story short, phone falls out of my pocket about 1ft onto a laminate floor and the whole digitizer decided to crack (so much for really strong screens). I've ordered a replacement digitizer but i cant seem to find anywhere on this ever so vast internet, what adhesive I need to attach the new digitizer.
the phone is running cm7 so i really don't want to go through the hassle of re-flashing it with a stock ROM in the hopes of getting it repaired under warranty.
very stressfull week, and now this think im gna go sit in a corner and cry
Any help is really appreciated

Any retail strong glue would do the job as what I see here. Just the case of how details is your work would come. If you do it slow and details without any rush or interuption, I think it will turn out like new you wouldn't notice it has changed the screen.
I've seen a video clip, a guy changing the Defy crack screen and it turned out very dirty. The glue just spread out all over the side of the screen.
You could just do a few practice of using the glue on a different object that required sharp and details hands/fingers and then only come back to work with your delicate DEFY.

Thanks for the quick reply
if the video is the 3 part one where fixes the screen and forgets he hasn't charged it then i watched that a few Min b4 my first post.
Google'd the names on the adhesive he used and got no results besides music cd's lol.
Would using the wrong kind of glue affect the touch screen? I don't really care about the waterproofing as it will be inside my wrist strap all of the time whilst im on my bike, but i just want to ensure that using the wrong glue wont render my new screen absolutely useless.
My town is riddled with phone repair shops. I got quotes from 4 of them, for just simply glueing the digitizer to the faceplate. Lowest quote i got for 5 min work was £20......... daylight robbery!!!
And my fingers are very accurate for some reason (apart from when trying to hit a link on the defy browser without zooming in grrrrrrrr), glued the trim on my les paul guitar easily, still give it a few practises tho
again, thanks for the quick reply

Good...
A good practise is to pour the glue like a water drop on a paper and use a sharp holder like twiser or a pin and take it a little and spreading it along the side of the Defy screen frame evenly.

How to Replace your Scratched Galaxy S2 Screen DIY

I have searched high and low for an answer on how to replace a scratched screen of the SGS2 by yourself and have finally found the answer.
This will definitely VOID YOUR WARRANTY so don't say you haven't been warned.
I suggest you only use this guide if you were desperate like me. My phone didn't come with an official warranty so I was as good as screwed if I wanted a new screen.
Step 1: Obtain the part
Just ebay for lcd screen and digitizer galaxy s2 (however u may wish to buy it with the faceplate see below note). You want both the super amoled plus screen and the digitizer together. You can get this for about 120-130 USD.
There are some vendors that sell just the 'lens' but you need a specialized machine to replace it and is simply not worth the trouble.
Note that if you go to an original Samsung service centre, when they order the part, it comes together with the face plate and is therefore a breeze to install. This part is for sale on Ebay too. http://cgi.ebay.com/LCD-Touch-Digit...312?pt=LH_DefaultDomain_0&hash=item3a682b9ad0. I would recommend you to buy this type instead of just the LCD and digitizer.
Follow this disassembly guide (not mine).
Now using a thin metal flat tool with a wide flat surface area, dig at the small gap from the top of the screen and pry the screen from the frontplate. It is held entirely by double-tape so don't worry about any screws, catches. Be careful of not damaging the bezel in the process.
Clean off the old black tape and double tape as best as u can, and be careful of the bottom buttons. The attachment shows how it looks like after cleaning it.
Reapply the double tape in strips and try to shape it to fit as much as you can. This is tiresome but necessary since the adhesive behind the lcd screen is very weak and you don't your screen falling out of you halfway.
Push it in and it should stick. That's it! Then reassemble.
Confirmed working!

thanks for the write up, do you have any more photos of your process?

OMG, it's like watching an autopsy.

Could a better resolution screen or even 3d screen be used/upgraded later on?

Nice to know for something happens, Hope not

Hope wont be necessary. How did you scratch the screen so hard that it had to be changed? I tought the Gorilla Glass is almost unscratchable.

Man,,u shud handle it a bit gently ,,,,i mean,i flinched every time u "threw" the phone on the table.

On second thought, I might as well buy that screen protector

Unfortunately not at this time. I will do it the next time around (which will be soon as there is a slight imperfection with my button sensitivity so I might be inclined to try it again) but trust me it's not a beautiful process. Needs lots of guts. Nothing technical about it. Shove the flat tool in the gap and keep on loosening the glue as much as u can then take it off.

It's more like cracked. I dropped it on some rocks from waist height and it cracked. It seems that gorilla glass is not shatter proof. There are also some scratches/mini cracks from where the rocks cut it.
Lesson learnt, get a screen protector that hopefully will reinforce it a bit more.

I wonder how these replacement parts compare to the quality of the original parts.

Is your new screen a Super AMOLED+ screen? all ebay listing just says LCD. Is it original Samsung part?

There some listed as Super AMOLED+ screen just search on ebay or even drop the sellers a question about their iteams.

It is a Super Amoled + screen (don't see any difference in quality between the old and new one). Most sellers don't really know much of their products unfortunately but they do say it's original and I do believe mine is.
There's no Samsung print on the front plate but it does have a part number which corresponds closely to the original one. Everything else looks exactly the same, even the black sponge at the back and the microchips have Samsung wording on them.

Dropped SGS2 from bikemount : broken screen.
OK,
I broke my screen this weekend. I was on a bike tour with the SGS2 mounted on the steering bar. For some unclear reason, the universal holder came off the bikemount at 25 kmh... Dropped on the paved road, and although still in the universal holder, which is made of soft rubber (which I would expect to break the fall), the screen of my beloved SGS2 was cracked !!! Apart from the cracked screen, everything else seems to work as before.
So, today I ordered a replacement set with bezel from aliexpress.com at 148USD.
When I get the part, I will try to post some pictures of the replacement process.
I had an HD2 before ... just sold it last Friday :-( ... I think over a period of 1,5 year, I dropped the HD2 about 6 times on hard surfaces ... also it fell off my bike once ... the HD2 never broke.
So, is it just bad luck this time, or is the built quality of the SGS2 just not as good as the HD2 ?
Regards,
DirkB

It is very easy to do. Just unclip each component and transplant it to the new case.

I have to do my friends one this weekend as he has dropped it and damaged the screen and the bezel .
I have managed to source the screen and the bezel for him all as one piece .
Now all the guides i have seen just rip the phone to pieces , surely if we have the right bits like i have bought this fix is very smple to do??
I am thinking it is just a case of undoing the 7 screws at the back of the phone , opening it up and then disconnect the screen cables from the mainboard . Does the whole front then come away??
If not i take it i have to undo the screws on the main board to release the screen? but this means the componets of the main board may come loose etc??
Has anyone that has done this got any info on just swapping the screen with the complete part? when i say complete part i mean the one that comes with the bezel and home button etc like this
http://cgi.ebay.com/LCD-Touch-Digit...312?pt=LH_DefaultDomain_0&hash=item3a682b9ad0
Thanks in adance for any guidance

+1 for me.
I received my screen including bezel.
I've removed the main board just like the guy in the Youtube video.
But now I still have to transfer (from original front to my new front):
- the bottom PCB (where the microUSB sits)
- the camera
- the speaker
etc ...
I can not find a description/movie of how to do this ?
The bottom PCB for example has 2 screws, but after removing them the PCB itself looks like glued to the front assy'.
I prefer to see or get proper instructions before starting the rest of this adventure
...
PS : I got my part from aliexpress.com within 2 weeks (via airmail). It's with the Samsung logo on it and the package included all required tools (screwdrivers) to do the job. Would be nice to see some written instructions included as well.
Grtz,
DirkB

Digitizer replacement

Hi, has anyone replaced their digitizer on their desire z/g2? How did it go? It looks easy on the youtube vid.. have any problems? What way did you use to melt the glue? What digitizer did you use, where from?
Any info much appriciated as will be replaceing mine v soon due to 'invisible finger problem' that's driving me nuts..
Thanks..
Sent from my HTC Vision using XDA App

Never done it on a g2 but should be pretty straight forward especially with a video lol. Use a heat gun to melt the glue, pretty much the only tool you SHOULD use to do something like that.

I replaced the digitizer on my third G2 after getting a refurb replacement from T-Mobile that had a black spot inside the actual digitizer glass, not on the outside or inside.
The process is very easy with the video, however, trying to keep dust and fingerprints from getting on the inside of the phone while you're trying to get it back together is a serious pain in the rear! If it's the same video that I watched, just use a hair drier blowing hot air to heat the adhesive on the inside of the digitizer and then pop the digitizer off very very slowly, because you don't want to accidentally bend the metal bezel around the screen.
You also may want to leave the original leftover adhesive on the inside, because when I cleaned mine off, light now always leaks out around the bottom edge of the digitizer, below the menu, home, and search buttons, even though I used the double sided adhesive strips covering the entire length of the bottom, so light shouldn't technically be leaking out. No biggie, though... it works like brand new, now!

Thanks for the reply.. I have seen that video and that's what I was using as a guide.. I ordered the digi today, should be here tomorrow.. the only thing I was wondering was the glueing process, as I have not ordered the double sided glue/tape stuff, as I was just hopeing to still use the original glue as I think you are saying.. I hope that works! Have to be careful like u say with dust/fingerprints etc..
Sent from my HTC Vision using XDA App

Hmm, after reading your post again, maybee I should of bought the double sided tape afterall? Do you think the old leftover glue is enough for the new digi?
Many thanks..
Sent from my HTC Vision usingall XDA App

Run over to radio shack they must have some kind of glue you can use lol. google cell phone screen glue see what info you can find.

Ok, just incase anyone is interested, got my new digitizer, followed the video, used a heat gun cerfully to melt the glue, pulled the old digitizer out, and used the original glue whilst still warm to hold the new digi in, as all of glue stayed on the case rather than on the digi, which was pretty lucky.. put it all back together and everything perfect, touchscreen back to how it should be.. cost me 17 pounds.

How was this accompilshed?
I replaced the touch screen as well and the problem persists. Plus I never ran into a part that required a heat gun did I use the wrong item?

A VERY confusing part is getting the midframe to hold to the hinge mounts. The side (black dots all down it) should overlap the stabilizer bar on the hinge. I fidgeted with it for hours until realizing it goes over, and inadvertently damaged the highly sensitive LCD screen, which resulted in me taking the whole thing apart again to replace the LCD and digitizer. UGH!
DO NOT get the cheapo digitizer on Amazon, look for one with gray spots where the menu, home, back and search keys are on the back side. The digitizers without them will not work when you swap over the white button caps on the back. I feel like this information is vital to anyone who is replacing their G2 digitizer, but most guides and videos make no mention of it.
I used a lamp to heat up the glass to remove it the first time. Took too long the second time so I used a hair dryer.

So which digitizer did you end up buying and which guide or video did you follow? I am about to tear mine apart and could use the info.

Hi, I did buy mine from amazon.co.uk, there were a few for sale,, the one I bought was supposed to be a genuine t-mobile g2 replacement (refurb I think, pressumably this just means that it was from a second hand g2 that had problems and the digi was taken out - and I'm pretty certain this is the case as mine has a thin film (which u leave on) over the back of the digi covering the tracks etc, which had a few very small air/dust bubbles under it (just noticeable when screen off), where I own a desire z, so now it sais t-mobile instead of htc, but I can live with that.
The small grey bits that you talk about were floating about or stuck on my digi when I pulled it off the main chassis. I had a look, and as far as I could work out, were possibly just for giving colour to the tiny led's that give you light to the home/search keys etc (I may be wrong on their use), but if you look closely, the tiny grey things have even smaller rectangles on them that relate to the positions of the led's on the circuit board. So I picked the remaining ones off the old digi, put them back in their correct holes and stuck the new digi in. I've had no problems (with a digi from amazon with no little grey things on it) so far, but maybee this is due to mine being a second hand original part..
Edit : Now after reading your post again, you're talking about bits that are actually on the digi itself, not the white caps that I'm talking about! Whoops. I didn't notice any grey spots on the digi itself, but I guess I must have them..

i just replaced mine with this one:
http://www.ebay.de/itm/230685692541?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
actually it says HTC on it and looks a lil bit differently than on the picture.
never the less, i replaced it really carefully and checked every connecting.
But somehow the Touchscreen doesn't work at all.
Can anyone help me ? what could be the problem ?
Wrong digitzer ?
is it okay, that the digitizer has direct contact to the frame where it is glued to ?

Hi!
I have the same problem, I have asked it already here
So you had invisible finger press in the screen, and the screen was bad responsive?
...Just to make sure my problem is digitizer problem! The service wont change it in warranty unless the problem is there all the time! But its driving me crazy! why is it happening randomly, why isnt it all the time? How could i make the screen to do this problem when i'm at the service?

[Q] build quality & service

Well, I got my Nexus on thursday, but immediately I noticed a problem .
At the bottom, the glass is slightly tilted, on the right is raised above the frame, while on the left is recessed ...
these are some pictures I took
I talked to the shop and they told me that they will solve the problem (repositioning of the glass) ...
What I wanted to know is what happen when the phone is opened, because on my current Nexus One, after first service, i have tons of dust entering between the display and the glass, and obviously I don't want the same thing also on this phone
So, do you have some experience with samsung's assistance ?
thanks!

anyone ?

As long as it's purely cosmetic, I wouldn't risk (or waste the money) having some guy open the phone to even out the glass.
Mine is the exact same way at the top of the screen, and I only noticed mine a few weeks after having it just because I was looking very very closely at the screen.

However, the problem it's quite visible on my phone, the difference between the two corners is about 1 mm, and with the glass that protrudes from the frame is even more subject to scratching ...
I don't know what to do ...
there is no one who opened the phone ?

The what you call a "glass" is the whole screen, so there no any way you get dust particles under it, as there no "under" , maybe the glue that hold it not have not dry good, I remember SGS2 have some yellow tint, or maybe it was SGS1, anyway things like that do happen to some devices.

Are you sure?
I have always found that touchscreen ("glass") and the display are two separate things

I'd return it for a replacement, that's an obvious build defect cite that you fear it'll either get worse or become a leak source.
Also, I am relieved I don't have this issue although I'd expect that I'd notice it quickly as you

[Q] Huge crack across screen!Need some advice.

Dropped my phone on asphalt today and got a big hairline crack across the screen . (Attached pics)
It really hurts cause i always baby this phone and just the rush to get to work and in my car, completely missed my pocket.
The screen is still responsive to touch and seems to be working normal thank god the lcd screen wasnt damaged and the digitizer didn't shatter.
Got a few questions t
1) just wanted to clarify that the digitizer lies ontop the LCD screen?
2) and that is all that needs replacing?(from damage seen in the pics)
3) also mine is branded just HTC(no carrier, so it's international GSM version?)
4) would it matter if i bought a replacement digitizer meant for the at&t version or not?
5) should be getting a one x that had some water damage and is no longer working. would the digitizer from this phone be a viable option for me to use as a replacement or should i just order the part online.( I really want it replaced fast and if i have to order the replacement it will take about a week to 2 weeks to arrive in my country
so apparently i can't attach any urls until i make 10 posts or i'd show u guys the part i wanted to order but its basically just a screen digitizer from ebay with tools needed for about $17.86.(is that cheap, good or expensive price considering the item + tools)
can you guys please search for it on ebay?the title of the post/part is Touch Screen Digitizer Glass Lens Replacement For HTC One X S720 + Free Tools
the link above is the item i'm looking to order for replacement. is it the right part i'm looking at?and would that be all i need or is there anything else i should add?also quality wise would it be top pick or are there any better options available?
Attached some pics also.Advice would be greatly appreciated.

You are unlikely to be able to separate the digitizer and lcd without damaging the LCD.
A water damaged phone may have a water damaged screen.
Search one of the other broken screen threads for more information.

I've replaced several screens on captivate.easiest way is get replacement(LCD+digetizer) from ebay,Google procedure.watch or read as many times as needed to feel confident to take apart phone.the hardest part is seperating LCD from phone(they use adhesive to secure LCD to phone).I used razor to carefully cut adhesive.
Most components are plug&play.just follow guide completely,u should be fine.
My LCD was $85 on ebay.good luck.
