Short of your spilling liquid on the tab, or using it in a steam room, I can't see how it can seep in between the two glasses. Anyhow, I think you would have to take apart the tab before you can remove the moisture.
If you're willing to do that, and the display assembly is original, the lcd is taped to the back of the digitizer. Since the original double-sided tape is not porous enough for steam to filter through quickly, heating the glass from outside will cause the moisture to evaporate, and condense into drops again at the top of the lcd.
What you need to do is slice a small opening through the tape at the top so there's some space between the glasses, then heat up the front surface. Once the moisture's all gone, press the glasses back together gently. It doesn't take much pressure for one to stick to the other. You want to close the opening to prevent dust particles from getting blown in. That should take care of it.

[Q] Can the digitizer be lifted to clean out dust

Obviously the dust is a big problem. When watching digitizer replacements I notice when they take the digitizer off they just heat up the face and pry the glass off with a plastic tool. This may be really stupid but can you just heat up the front to loosen the adhesive and lift up the digitizer to clean the screen? Then just either put new adhesive or whatever you may want to secure screen again? Sure you can send the phone off but there are still instances where dust comes back. At least this way you personnaly know if you fixed the problem.

[Q] DIsassembling Gorilla Glass from screen

Good morning, i noticed some black points under the Gorilla Glass of my Trasformer.
They arent't dead pixels, i noticed them also when the device is off.
I think it is like black dust.
Can anyone help me : I want to disassemble the gorilla glass, to clean it.
Is it possible to disassemble gorilla glass from the screen ?
Thanks Gabriele
I don't know. But are you sure you will be able to do it in dust free enviroment so you don't get more dust inside that there was before?
I once tried opening LCD monitor to check if can change the backlight (that was going weak with time) and it was almost imposibble to get inside without taking apart everything, every layer etc.
maybe this helps

It is relatively easy to take out the glass if you know how. That said, not going to tell you unless you have a dust free environment to work in. If it was me having dust in there I wouldn't do it.
There is a black point under the glass, probably black glue in the botton right corner...so i will try to clean it...if i will know the right way to open...
There was a thread where a member reported using a hair dryer to soften up the glue. Be careful not to damage the digitizer if attempting to do this.

Replacing the tab 2 7 digitizer

My Tab 2 7 had a swirling crack on the digitizer (touchscreen). Looked for a tutorial on how to replace it in vain. Saw the teardown at Tech Republic, but that's it. No mention anywhere that I could find about how to do it. Decided to bite the bullet and ventured to fit a new one. Successful. Wrote down a quick guide thinking it might help someone since I saw a bunch of tabs with smashed digitizers on Ebay. Some claim it's gorilla glass, which makes me kind of wonder why they shatter so readily. I know, gorilla glass only scratch-resistant, but still...
Samsung sticks the digitizer to the bezel-frame with a tough double-sided tape, similar to the kind Asus uses on its tabs. A tutorial for the Tab 2 10 shows the use of a putty knife to scrape the digitizer off its frame, which wouldn't work with the 7, as its bezel-frame almost totally covers the edge of the glass back side. On the other hand, inserting anything metal in between from the front would scuff it badly.
The LCD display was taped to the magnesium frame, but is separate from the touchscreen, which need not be removed when replacing the digitizer.
What you need to do is to follow the steps in the teardown referred to above. As Tech Republic correctly pointed out, the internal layout is quite neat, unlike some of the tabs I've had the chance to disassemble. There are many thin cables, however, and you need to proceed with patience.
You must remove all components, so that only the frame with the digitizer and LCD is left. Eventually, you'd have to employ some source of heat, be it a heat gun, a hair dryer or a heat lamp to soften or to some extent melt the adhesive of the digitizer. Leaving any electronic component in place and the heat might destroy it. You can use brute force to separate the digitizer from the frame, but you'd more likely than not damage the LCD in the process.
What I did was use a heat gun at ~500 F, held at about 1 to 2 inches from the edge of the digitizer, and went back and forth over it, one side at a time, for no more than 30 to 35 seconds. I used a blunt object to push the glass out at spots plainly visible as illustrated in the attached thumbs below, then slid a plastic tool with a flared end to pry it from the bezel along its edge. Be careful how you handle the frame, since it would get burning hot at this point. As I moved from one side to another, I wedged a guitar pick between the glass and the frame to prevent them from sticking back together. You might pulverize parts of the glass as you go along, but in general it flexes quite a bit and wouldn't shatter.
Once you get it out, you need to remove the residual tape on the frame. The digitizer I bought was lined with new tape so I didn't have use any extra adhesive. It doesn't bind as strongly as the original tape, but enough to hold everything in place.
Putting it back is just the reverse. I took the extra step of reassembling the whole thing first with just the digitizer hanging loose, plugged it in, turned the tab on to make sure it functioned correctly before bonding it to the frame.
Basically, the process is nothing new. However, just the fact that someone has done it might give confidence to other DIYers in the future. Feel free to ask if any questions.

Thanks im going to give it a go. Any walkthrough tips by anyone else appreciated
Replacing the digitizer on this device is among the easiest ive seen. With no heat or taking anything off except the back I fixed one with only an isesamo

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

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?

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.
