    ill start with a little back story. I dropped my phone and broke the digitizer(LCD intact). after reading around for a bit I decided to try and replace just the digitizer. so I bought a new one and tried separating the LCD from the old one. sadly I accidently cut a wire on the LCD while removing it, so it doesn't work. as it sits I have a perfectly functioning digitizer and I'm wondering if I buy just the LCD would I NEED to glue them together? would it be suggested to buy the pre-glued set? I figure if I could buy just the LCD and NOT glue it, then, should something break in the future it would be considerably easier/cheaper to fix. I talked with a local ipod place (that told me my phone doesn't exist! lol) and he said when they fix newer ipod's that are similarly glued they DO NOT re glue them and I should be fine.

    Thoughts?

    how strong was the adhesive that held them together? I did a similar repair on my LG Spectrum, although the lcd has a light adhesion to the digitizer, no extra adhesive was required for installation. However you do need to make sure there is good contact all the way around, if not you will get back light bleed like a mofo. It took me about 10 times of pulling it apart and putting it back together, when i realized i need to put the lcd and digitizer together 1st then put the rear housing on. I haven't been into the G2 yet though. I'm not sure where you got your parts from, but repairsuniverse.com sells the combo and has how to video's that may help you.

    uhh, compared to other phone adhesives I have no idea. in the grand scheme of adhesives it was fairly weak. I did try putting it all back together to get a feel for how it would reassemble and it seemed to be a pretty snug fit. still, without a new LCD I guess I couldn't be sure. thanks for the heads up about light leaks. I bought the digitizer from amazon and I think ill go that route for whatever other part I buy(lcd/digi combo or just lcd). I checked the site you suggested and saw no tutorials for my phone and their prices seem fairly steep. still thanks for the suggestion. :)

    Did you do a deep dive, maybe look at YouTube videos for others fixing their devices (I know, probably different make and model)... My personal choice: I'd probably go the combined Digitizer LCD route.

    deep dive? I checked on youtube and read a bunch of forums. I didn't see anything saying I had to re-glue but I also didn't see anything saying I could get away without it. most of the tech stuff just says don't try separating the 2 because something will break and doesn't go into any further detail. since I already have a new digitizer I should be able to just buy a new LCD and be fine(aside from the possible light leak). at least that what I was told by an ipod guy....... I'm wondering if anyone has experience with this.... I cant be the only person to have had this problem/question.
    if I have to buy the combo that's fine but why waste money on a part i don't need and make future repair harder.

    i did a little research. Everything i have seen has been digi+lcd combo. You may be better off going that route. Appears to be similar to GS3 where you can split them but your really better off doing the combo. Amazon has a fairly loose return policy, have you looked into returning the digitizer? Or try posting it for sale here on the forum.

    Yeah. Make it someone else's question to solve. :)

    +1 on Amazon returns and their policy. However, OP probably purchased through a 3rd party via Amazon. Then you have to check.

    Yeah quite a price differential between the combo, and the digitizer only, specially for the VZW version. I don't know why...

    alright, its update time! so i decided to try going with a separate lcd and digitizer because no one could answer and i don't mind being a test subject. with everything set back in and connected the lcd was fine and the digitizer worked though it was kinda jumpy because it wasn't secured to the frame. i tried to connect it all together starting with cheap glue which didnt fully attach to the digitizer so it continued to jump, rubber cement which worked for several days but came undone after a little wear and tear, and now double sided tape which also has worked well. unfortunately i think i may have damaged the connecters with all the on/off because there are a few dead spots on the digitizer. it doesn't jump but becomes unresponsive when i swype to a certain area then will pick up again after i pass through it. i will forge ahead and buy another digitizer to see if this is the case....... until later :)

    Thanks for the update.
    So are you going for a combo or the digitizer alone?

    If the latter, how are you going to attach? Have you settled on a method? Is there special glue for this operation?

    Sorry to hear of all the trials, but your reports should prove very helpful to others. Please let everyone know how it goes.

    repairseuniverse.com sells some kind of adhesive strips for the types that have to " glue" together.

    This is why you go to a repair store to fix it. Think of how much time, effort, and money you have spent already. Not to mention the fact the repair store will do a better job. :rolleyes:

    @dportal but then we would never learn! i dont mind the time spent or the money, i now know allot more about my phone. :)

    @stef7 i will try another digitizer to see if that helps. im hoping it is actually the connecters on the the digitizer not the board. :/ either way ill find out soon. as for attaching i liked using the double sided tape the best. didnt have to deal with waiting or possible shifting while drying ect. plus you can more accurately apply the adhesive.

    I like your attitude... sometimes you have to make the effort to gain true operational knowledge.

    I know that this is an old thread so forgive me for bringing it back up to the top of the list.

    As a repair professional having worked on many of these phones, I thought I'd chime in and provide whatever useful information I could provide especially for anybody searching Google look for answers.

    As far as the LG G2's digitizer, the OP's digi is effectively dead. Dead spots are usually caused by low-quality digitizer assemblies and are commonplace when doing a glass only repair. However, this may be a cause of function degradation over time which I'll explain shortly.

    One of the problems the liquid optically clear adhesive (LOCA) solves is glass flexing. The glass used on these phones is particularly thin. And, as I'm sure the OP has seen, the slightest pressure causes the glass to come in contact with the LCD producing the 'bubble' effect that many people see in phones and devices where LOCA was not applied after the repair.

    On many phones, particular Samsung devices where the digitizer is adhered to the LCD instead of the glass, this only shows up as a cosmetic problem. On the LG G2, unfortunately, the bowing and flexing of the glass actually causes damage to the digitizer over time causing those kinds of dead spots and eventually complete failure.

    You can usually get sheets of 'loca' from online suppliers like those found on eBay and Amazon. While these generally do work, they never look as good as the original, especially if there are small scratches on the surface of the LCD and when working in an environment that's not dust free. For most people, that's not a problem. Personally, I would recommend just buying the glass/lcd assembly as it's already been assembled with LOCA and cured under UV light. So far I've had very few problems with them. It's usually cheaper to go this route in the long run even though these assemblies are usually around $75 ~ $85. The end result is a lot better.

    These phones are well built. The only real flaw I see is in these designs is that the digitizer is attached to the glass so as soon as the glass breaks, the digitizer almost always goes with it. Samsung Galaxy devices don't have this problem which is why they're more suited to glass-only repairs.

    To the OP, I hope you've been able to solve the issues with your phone! It sounds like you learned a lot about them and I hope you appreciate the design choices that went into these phones -- it's one of my favorite phones to work on.

    Im glad there are people out there that are willing to try to fix there own stuff. missing up $50 on a lcd and a digitizer is one thing. But he is learning to fix the problem his self. He will break another phone and then he will start saving when he knows how to change it his self. Thats how I got started. Pays between 400 to 700 a week fixing cell phones.

    Sorry to bump this tread.

    But i fix phones to and i have much problems with the screen assembly attaching to the bezel. The all come off after some time and the light leaks between bezel and glass.

    I order some complete assemblies and they have it all to. The glue space is very small on the lg g2 frame that must be the problem. But am i the only one and if no how did you solve this.

    THanks

    I paid a repair guy to fix my broken screen, and I ended up having to go back to him about a week later cause the glass was peeling up from the bezel. He had to take it apart and re-glue it, only this time he went extra thick on the glue. I ended up with a little glue around the edges, but it came off, and the screen has held up fine since the last repair. I think that gluing it a little thick and then cleaning up the bleed out is probably the best way to go.

    He does it with liquid glue?
    I only use adhesive M3 tape.

    As far as I can tell, yes. I didn't hang out the whole time that he was working on it, but I saw a little bit of his process. These are just my findings after receiving the phone back.

    leeor_net, It's great you know so much about these phone so I will ask you this question.

    I picked up a used LG G2 from Ebay. The phone is in somewhat great shape and is functional except for the top portion of the digitizer. About an inch, give or take, at the top is unresponsive to touch. I just wanted some input on how common digitizer damage is on this phone.

    I know most phones these days are very delicate and the digitizers and LCD's can be damaged quite easily. There is a good knick at the top of the phone so I am guessing it had been dropped at one point. It does not appear the digitizer had broken or shattered and was replaced but honestly, I cannot really tell if it was.

    I paid $150 for the phone and I can pick up the LCD, digitizer, and mid body assembly for $65 on Ebay. Just have to slap the internals in the new mid body, throw the back cover on, and done. Phone is good as new. But I don't want to make that investment IF by some chance the problem isn't the digitizer but rather something wonky with the main board. The more input the better. Thanks

    Has anyone figure out how to solve the problem of the light bleeding?


    I have bought the pre-assembled LG G2 digitizer/LCD from ebay from two different sellers (one in springfield MO, the other in Westminster,CA) and both of them have the light bleeding out.

    I lifted up the screen a bit on one of them with a guitar pick and used a tiny pin to apply some loctite go2 glue on the sides (recommended by someone on youtube) then used C-Clamps to clamp the screen to the frame, but when I took off the clamps (after 24 hrs) I could still see some light bleeding through, not as bad as before but it was still there.

    I plan on buying a new screen without the frame attached and trying again. But i'm not sure what I should use. I've been reading that super glue isin't shock resistant so if you drop your phone the glue would come undone and you screen might lift up out of the frame. Maybe rubber cement would do the trick? Or what else is there that I can use?



    FYI if you don't know what loctite go2 glue this is from their website "Loctite go2 glue is a true all-purpose glue that delivers the power of 2 technologies to create Durability & Versatility. Mixing the strength of Polyurethane & the versatility of Polyoxysilane, it is the best formula for your repairing, crafting & building jobs." It is supposedly shock resistant so that's why I used it, however it didn't work too well because there is still some light-bleed.


    Please advise as to what I should use to fix the light-bleed problem


    Thanks for all your help!
