A while back my phone fell out of my hands and onto tiny rocks which resulted in a broken tempered glass protector and a broken display all at once.
Because the display breaks more and more and parts of the underlying electronic becomes visible, I'd like to replace it.
The question is: Should (or could) I use liquid adhesive or should I use adhesive strips? What's better?

Hi, has anyone disassembled omnia 7 screen before? May I know whether the glass and lcd are glued together and whether it is difficult to pry open the screen? (I have pried an ipod touch screen before)
*I just broke my omnia glass and thinking of getting a replacement from ebay but the lcd and glass package is too expensive (>$100) while the glass only is below $20 so I was thicking of getting the glass only.
Thanks
First of all, how the hell did you manage that - it's Gorilla Glass!
There is a tear down of the phone here
Quite complicated and delicate process unless you are familiar with doing this kind of thing.
As for the glass being connected to the digitizer, yes I think they will be stuck together with some sort of glue resin. Probably not the best idea to prise away and try and fit yourself, I suspect you'll be disappointed with a homemade attempt to stick a new pane of glass on.
I actually couldn't find the glass-only on eBay, I could only find the £80+ glass and digitizer items.
Claim it on household insurance, send it back to Samsung or save up the £80?
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've decided to go naked with my Nexus 4. Having dropped it once already and cracking the back, I'm curious what would be involved with fixing a front display crack.
The LCD display is located behind the digitizer glass, so if you manage to break it without breaking the exterior glass then I'd be impressed (without opening the phone from the opposite side).
wait i think i'm mistaken, so the actual glass that i'm touching is the digitzer?
i'm under the assumption that it's glass>digitizer>lcd display and that when the phone drops, only the glass breaks. my question under that assumption again is does the digitizer also get damaged?
Well you are correct, the digitizer is the thin sensor layer behind the glass, but the trend with touchscreen phone is they're glued in together with the glass as a single unit, and I don't think they even sell them separately.

There is a youtube video to replace the glass/digitizer, but its looks like it will require some patience. It doesn't help that LG tape the digitizer to the LCD to make them seamless as well, making the process harder: http://www.youtube.com/watch?v=paRc_n4uB8s
Hey guys! Alright, so, a clumsy fashion student knocked my Nexus off the table while it was charging in class, but I was quick enough to somewhat save it by stopping the initial impact of the cement floor by lightly "kicking" my phone with my shoe, so instead of smashing to the ground it instead slid across the floor face down (but not too violently). There's no serious damage at all, the sides, corners, and back are all scratch-free, but there are a few scratches on the front screen that I can notice (might be a bit OCD, who knows).
So I looked around for replacement glass and found these. Now, would this be want I would want to get if I wanted to replace the front to get rid of the scratches? Also, if anyone could recommend a good and not too expensive brand for screen protectors, that'd be wonderful as well.
Thank you, guys!
You probably want to go to ebay instead and get the digitizer replacement so it come with both the glass and the digitizer, otherwise the one you linked won't have any touch ability.
Replacing the glass/digitizer is not an easy process, but you can check out this youtube video: the glass/digitizer is glued onto the LCD, so you need to heat it up, seperate it while not damaging the lcd, clean the glue, then replace the glass: http://www.youtube.com/watch?v=paRc_n4uB8s
You can try XtremeGuard which is a wet applied screen protector and its pretty cheap. If the scratch is small enough it will be hidden by it: http://www.amazon.com/GOOGLE-NEXUS-XtremeGUARD©-Screen-Protector/dp/B00AA281D6/
Skinomi is another brand. I like XtremeGuard more than Skinomi because I can trim it easily with a paper cutter while keeping the edge straight and its easier to install, but Skinomi material is better quality, thicker, and smoother feel.
You can also get tempered glass screen protector which is more expensive, but easier to install. I had an iloome version, but it cracked in half when I tried to peel it off to readjust it.
Right now I'm using XtremeGuard and this bumper: http://www.amazon.com/Google-Nexus-E960-Bumper-Case/dp/B00B199960/ These are cheapest alternatives, but I like it best so far.
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.
