Lately my screen has become a little bit too sticky - my finger does not slide as easily as it used to be (it's not my finger - same applies when I rub the screen with a piece of napkin for instance) even the backplate has less resistance. This is quite a problem - swype for instance becomes quite unusable..
Could it be a kind of damage to the coating (if any)? I have used on the screen the usual hand cleaning napkins - could these things have damaged the screen? Is there any coating on the screen or is it just some kind of special glass?
How do you clean the screen and how smooth does it become (some times in the past the screen was extremely smooth - don't know, however, whether this had to do with accumulation of oils from my hands).
Thanks
do you mean thoes napkins with alcohol on ?
I use a microfiber cloth and it works nicely.
stop using it to watch porn
but seriously, what kind of hand cleaning napkin have you used? some tissues have moisturizer in them and I don't think that would be good.
If the problem continues return unit as it sounds like hardware problem. Next tine get a screen protector. Also clean your fingers you grub

It's just going to be your skin...
People swet, people give off different amounts of moisture at different parts of the day... depending on temperature, mood etc etc.
Just wipe your screen on your t-shirt. Go wash your hands and try again.
Have you tried a screen protector or something similar?

Clean with window cleaning product and wash your hands ....
there is a cleaning spray with silicon, it also removes the antistatic part. I used it at work for scanners, makes glas surface more slippery. not sure whats it called.
i just use nothing! to clean my sceeen glass, more like, i just wipe it under my armpit
i'm referring to shirt sleeves

I think it has to do with your fingers and it giving off moisture. At one point, I thought the same thing. The screen would be very hard to swipe. Once I cleaned the screen throughly and washed my hands, it was back to normal, as in day one.
I use my t-shirt to clean or my eye glass cloth. It should get back to the original smoothness.
Thanks for your replies. I think the screen may be a little bit hazy as well. Maybe it is just my idea. I will try a glass cleaning product. I just hope that they're is not some kind of protective layer that I accidentally removed or damaged.

Sometimes a very clean screen may be more sticky....with use the oil from ur skin will make it easier to swipe...happened wirh me on sgs and iphone..

You are right. That was the problem. The screen now is a little bit more greasy due to the suntan and it works greatly again. So the screen is like sex: when it's dirty it's just better.

Greetings everyone!
The other day my wife's bag fell out of the car while she was exiting without either of us noticing. Inside that bag was her Nexus 7, which I promptly ran over with my car.
Much to my surprise, everything is perfectly functional as far as I can tell. Bluetooth, WiFi, Brightness settings, OTG, charging, etc... all great. The only thing I ruined was the screen of the thing.
Knowing the cost of a screen replacement, I think I'll forgo getting a new one. (I gave her one of my other N7s so this one is now a hack-device!)
My question for the fine folks of XDA is a two parter:
a) How can I safely remove the shattered screen bits without causing further damage?
b) What would be a good material to place over it once I have it removed? Glass? Some special plastic?
My idea is basically to end up with a non-touchscreen device and use OTG and ADB to maneuver around in it.
Thanks in advance!
I take it only the touchscreen glass is cracked and the LCD is OK?
If the surface of the glass is cracked but intact, just cover it with a screen protector. If the glass has shattered, you will have to carefully cut the LCD from the digitizer as the two are bonded together. Since the LCD is very thin, you might crack it.

I've experimented with a cracked screen. The lcd assembly is bonded over its whole area to the glass. The glue is softened by temperature (too hot to handle) but I was unable to separate a small piece. It's possible that heat + solvent could work but as bigbop says there is there is a massive risk in further damage

LCDs typically use a metal frame to hold everything in place. I have removed the guts of the LCD from a frame in order to make it easier to remove the frame from a digitizer on an old PDA. It may be possible to do the same with the Nexus display but you will have to remove the tape around the edges of the display away and bend the small clips holding the guts in place.
I think the frame is only bonded around the outside edge.

So what happened?
First some background: Current replacement guides for displays used on such devices as the GS3, HOX, HOS specify replacing the full-screen bonding agent with an edge-taped solution. This results in much lower contrast ratio due to a non-spec air gap and if done improperly, dust in the air pocket over time.
The *proper* solution would be a liquid adhesive lamination (LAL) or liquid optically clear adhesive (LOCA).
The requirements of these adhesives for this application are the following:
Code:
- OEM contrast ratio
- Dust abatement
- No bubbles in final product
- Rebondability
I believe the process for using these adhesives would be the following:
Code:
- Removal of all existing adhesive from substrate
- Application of *appropriate amount (TBD)* of adhesive in center of substrate
- Application of new glass lens with even pressure to spread adhesive outward, avoiding air bubbles
- Curing of adhesive if necessary
In fact, this seems more straightforward and less error prone than applying adhesive tape around the lens perimeter.
I am willing to try this on my screen, but...
What I need
I cannot determine which adhesive will work, or even work best. I'm hoping that someone has a lead on a proper adhesive through experience. Obviously a DIY fix would need only a small amount, so a gallon jug wouldn't be a good option (unless for a group buy or something).
I'll post links to the resources I have found already when I reach 10 posts
Found a reasonable amount of LOCA
I found some LOCA for $30 shipped, not sure of the quantity or how many applications it will provide. I think it will take some experimentation to find the correct amount to entirely fill the void without airspace and without squeezing out the sides. Might have to apply it with the screen out of the phone frame. Also, I do have a UV flashlight but I don't know if that is sufficient to cure this stuff. I'll test it out on some microscope slides. I'll also test whether it can be taken back apart via heat after bonding.
This topic is really interesting, since I broke my GS3 gorilla glass and would like to change it by myself. A good DIY would be appreciated

I ordered some LOCA so we will see how it goes I guess. I'll try to take pics/video when I can.

can you share link of supplier ? thanx
i would add few more steps to process for using these adhesives
- if OCA used, according to post from phonefreaks h t t p ://forum.xda-developers.com/showpost.php?p=31321004&postcount=13 alcohol spry on glass or screen before application OCA, then alignment, then again alcohol spry on glass or screen
- vacuum application to remove air bubbles
and i would search for LOCA which cures in "shadow" area

The link you posted is regarding a different adhesive, that is in sticker form. The adhesive I am trying out is liquid and hardens with UV light. I found some on ebay.
I bonded two microscope slides together as a test and it worked well, no bubbles. The only problem I had is that lots of adhesive leaked out the perimeter of the slides... it is going to be hard to determine the proper amount for my screen. I also need to take into account the perimeter tape adhesive if I use it but I might not even bother since the LOCA bonds pretty tight. Another setback is that the slides are really stuck! I haven't tried applying heat to break the bond yet but I have been unable to separate the slides.
On the brighter side, LOCA is nice to work with because it will not set until you want it to; if you mess up you can just try again as long as you have some adhesive.

theres some locktide LOCA dam adhesive, which has greater viscosity, its main purpose to create borders and not allow LOCA to leak, but i think double side tape would help to keep it in place.
Hope heat will help to separate, or we will get permanent glass replacement :/ and we all know how fragile glass are :/

I did see the loctite LOCA but it's really expensive and not sold in small quantities. Greater viscosity would be a plus; how do you know what the viscosity of my LOCA is though? I'll toss my slides in the toaster oven tonight and see if they come apart.
any luck on separation ?

Not quite. I perhaps did not let the glass heat thoroughly, but I stuck it in the oven at 190 for 10 minutes and then gave it a shot. I did not use a razor blade but rather a pocket knife so that didn't help, but the adhesive did clearly give; however, the top layer of glass broke. Not a big deal but I was hoping it would be a lot easier. The layer of adhesive wasn't rock hard, and it was very very thin so a thicker layer would surely give more easily. I could clearly see that prying in the glass was causing the kind of outwardly flowing separation that I would have expected so that's encouraging. I think I'll call it good enough and cross that bridge if and when my glass breaks again. As soon as I get my metal pry tool from hong kong I'm going to give it a shot.
Ok, so I have a Samsung gs3 and I broke the glass months ago. I also replaced the glass months ago.
When I replaced the glass it left a very tiny 1mm or less gap between the LCD and the glass from where the old glue use to be. This causes many problems because condensation under the glass and lack of sensitivity make the phone act weird and spaz out sometimes.
All I ask is if anyone knows what type of clear conductive glue can I buy and use to seal my glass to the lcd and end the problems.
LINKS APPRECIATED
Glues may cause a gap , no matter how thin u make it, better go for a dual side tape, which is thinner than glue, manufactures use them to stick glass to cell phone body,batteries etc..
I found it far better than glue, i get that from a full panel body replacement spare which i bought from local radio shack store.

I got my hands a E970 screen with a cracked digitizer. I hoped to use it to replace my cracked E960 screen,with a cheap 30 buck digitizer. So I carefully checked the pin-outs and it looked good. I then plugged it in and what do you know,worked just fine. So for what its worth,if its useful to anyone else,the LCD screen from an E970 will in fact work in an E960. Unfortunately it didnt work out. The screen,like the nexus 4 display,was glued t the front frame. I tried getting it out and ended up destroying the lcd. However,I did experiment with heating the front and separating it with a molybdenum wire. That part seemed to go smoothly. If anyone else has to do this,heres my best suggestion. Get some sandpaper,perhaps 80 grit and glue it to a board. Then sand the edge,moving parallel to the plane of the screen until you have ground away the frame and exposed the edge of the glass digitizer. Repeat on all four sides. This way you should be able to get to the adhesive under the digitizer without further cracking any glass. Remember,the front of the digitizer is cracked,so the lcd is vulnerable. I would get a piece of window glass and cut it to about the same size as the glass digitizer. Then used adhesive transfer tape to bond it to the front cracked glass.
Keep in mind,Ive not separated one successfully yet,so this is a combination of a report of my experiments and my educated guess on how to proceed in the future. It goes back to a previous attempt I did on a broken LCD. I conjectured that if I were to separate the plastic digitizer from the FRONT glass,I could more easily peel it away from the LCD. SO I took separated about a mm of the digitizer from the front glass. Then I ran a qtip dipped in acetone along the edge. The acetone was drawn into the gap by capilary action. I then waited a few minutes,repeated the acetone dipped qtip procedure,and then carefully slid the corner of the foil coated plastic package of a nicotine patch through the gap. The packet is very very thin,way thinner than a credit card,but very stiff. It easily removed another mm or so of the adhesive,and better still,left a gap,so that your not forcing the display to bend. This went well until I got near the last half inch of a shard of glass,about 1/3 of the way up the display. At that point,I applied a bit of upward force and that shard,about two inches long,with a sharp point,held only by a the last half inch by perhaps 1/3 inch section of adhesive shattered the LCD under the point. The lesson learned is,a cracked digitizer is going to have this lever effect on the shards that crack the lcd with a tiny amount of force due to the combination of the long lever arm and sharp point. So the glass is to hold that all together and keep it from doing the lever thing.
My experience tells me that ,yes,those techniques you see on the internet with the credit card and the heat gun MIGHT work,but your going to need a lot of skill. And that skill is developed by trashing DOZENS of LCDs. And its still not going to be 100%. Probably no more than 50%. My guess is that these were developed by people who repair these for a living. If you do,then you probably have a big box of broken displays. Some only have broken digitizers,some broken LCDs,and you think "If I had a way to reuse some of these parts,I could make a bunch of extra money" so you start with the broken ones,and then when you get something that works,even 50% of the time,you can make 50 bucks or more extra profit per screen you can fix,from parts that were previously worthless junk to you.
But I want something 100%,not for my nexus,but because more and more phones are made like this,and in the future they all will be. So I want to make a procedure that will fix it all the time. So far,I suspect that you have to choose one part to save. Either the frame or the LCD digitizer stack. I may try working around the edge with a plastic tool and heat with a glass bonded to the front and see if I can get the glass free of the frame without destroying the LCD,but Im not optimistic,first Id like a sure fire way to save an LCD.
My feeling is that if you bond the front glass to a ridged substrate,you can then use the sandpaper to grind the edge away. If you do it parallel to the plane of the screen,it should be very gentle on the display,avoiding any damage. Then you can perhaps with the aid of heat,cut the digitizer away from the frame. Im thinking at this point,you need a screen separator.
So Im going to make one. My plan is that I will make a device from plywood. It will have a backing and a part that slides. The part that slides will have a heated piece of aluminum with a thermostat that holds it at 175F and an inductive heating coil behind the aluminum. This "carriage" will slide back and forth,and there will be an guide that will constrain its motion to one axis. The "carriage" will actually be made from two blocks,one that will be in the guide,then a second that bolts to that,using some studs,and washers and wing nuts. Between these two plywood layers,I will uses sheets of paper as shims to adjust the height so that a 0.08mm molybdenum wire (I have 100' of it I got off ebay) is at the right height to separate the screen. The screen will be stuck to the glass with adhesive transfer tape,the edges ground away,then mounted to the separator with adhesive transfer tape,and shimmed to the right height. I can then heat it to temperature (the glue *I* use SHOULD be strong enough to hold it in place,if not,I just buy one of the higher temp adhesives. I can then separate the digitizer from the front glass AND the frame. At that point,the LCD should be free of the frame. Now,if the digitizer is OK,I can simply ,carefully clean the adhesive off of it and repair it using a 12 dollar front glass.
Some people use optically clear adhesive that is uv cured,because its easier to get a bubble free bond without a vacuum oven or autoclave so I will just use an optically clear adhesive transfer tape. I however have access to a vacuum oven at work,so I'm good to go. Even if I did not,I suspect that there are other options. I might try one of those vacuum storage containers they sell at target that go with those "food saver" vacuum packers. (I want one anyway to freeze food in,very handy. Buy 40lbs of chicken breasts when they come on sale for 1.89 a lb and freeze them! Pays for itself in no time) My hope would be that ,perhaps of first heated to say 180F or so,then placed on paper to avoid melting the plastic container ,you and a vacuum pulled,it would remove the bubbles. But I have access to the oven so I don't care much about that.
If not,then I can probably make sure the wire is on the other side of the digitizer and separate it from the lcd instead. Then the same procedure can be used to bond the LCD to a new digitizer/glass assembly. But first I need to find some more broken LCDs to play with. But hopefully my experiences will help others in their quest. The end result of what I have determined though is,Im going to have to make the separator,becuase while its obvious that its POSSIBLE without it,its just not reliable or practical.
