Cracked screen, what do i need? - Nexus 4 Q&A, Help & Troubleshooting

Folks
cracked the screen and my question is, what do i need to buy?
looking on ebay and the have Touch Screen Digitizer Glass Lens and then there is the more expensive Screen Assembly.
the screen is unresponsive but the lcd isn't cracked, would i get away with just replacing the touch screen and digitiizer or do i need the screen assembly?
Many thanks for your replies

Unless you have the skills and tools for separating the glass digitizer from the LCD, you're better off just getting the front assembly that has been pulled from another N4 like this one and fixing your phone in a few minutes (if you already know how to open the N4, which is really easy to do.)

Broken plastic "lens" replaceable

So today my phone dropped on the ground flat on the ground from about hip height and after picking it up i noticed i now have a cracked screen from the top.
I'm wondering how much the plastic front lens will run about. I see some prices online for about 100-180$ and it seems like every1 is pointing to the g1 digitizer?
The touch screen features work properly with no problems at all. I'm wondering, is that whats really needed? Or is there just the plastic lens somewhere?
Don't really feel like spending around 130 bucks for accidental damage. Might awell wait for a different phone to come out .
I know you can order just the glass but I have never needed to repair the glass or LCD on a G1 or MT3G. From just looking at mine I assume you can seperate the digitizer from the LCD.

the G1 digitizer is not a "plastic lens" it's the touchscreen, which sits on top of the LCD screen. I bought a replacement digitizer for relatively cheap on Ebay. If you are going to fix it be extremely careful. I managed to break the flex cable of my LCD screen fixing the digitizer....

[Q] Replacement glass or lcd

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?

Replace LG Nexus 4 Glass Front Only

Is it possible to replace the front glass without replacing the digitizer and LCD? I have saw many, many glass only replacements on eBay for it. I want to do it myself. Is it possible? I know it is possible for the galacy necus but as the 4's LCD is on top i was wondering on bidding for a cracked screen one on ebay and fixing the glass only.
As far as I know, the digitizer and glass are glued together pretty tightly, and it's extraordinarily tough to separate the two without damaging either; plus, if separate them you have the constant worry of dust getting in there. It's usually worth it to just buy a glass+digitizer that are glued together.

I have seen videos of people seperating them on the galaxy nexus. Also, if the glass is cracked is the digitizer gone too? because the touch doesnt work and its cracked.
I have done a teardown of the Front display before. It is not easy. Yes the Digitizer and LCD are Glued together and I HIGHLY recommend NOT attempting to seperate them without the proper setup to do so. Once they are seperated it takes a SPECIAL glue to glue the Digitizer to the LCD and it has to be aligned correctly or you have to go through the process again. ALSO the LCD+Digitizer display is GLUED to the Bezel with an RTV type substance. I HIGHLY reccommend spending the extra few dollars to get the 3 piece setup. With that the repair is VERY Quick and easy. Takes about 15 min or so. (Half of which is getting the Back cover off without breaking anything).

But one question. Is the digitizer broken if the glass is broken and it doenst recognie touches?
EDIT: I will buy a broken nexus 4 off ebay for a few bucks and replace the glass so I want to know if it works if you get it. And there is a 80$ difference between the glass and the 3 piece assembly

The Top Glass is the Digitizer, the LCD is just that. I think the iPhone4s/5 has the Digitizer integrated into the LCD and I think this is a process that may start to become commonplace as LG announced that they have a LCD Display with Integrated Digitizer in production now.

Yup You can see the digitited touch grid if you look at in the right angle in bright light.

The Glass IS cheap but they do that so they can trick you into wasting your money. It is not an easy process to do. I have done a replacement on both the fron and back and it was very time intensive. (The front I just ordered the 3 piece and it was quick.) For anyone who has had little to no experience doing display repairs I reccommend the 3 Piece set. If you have SOME experience and have GOOD tools get the 2 Piece. ONLY get the Glass Digitizer IF you have Some professional tools and experience. Also the Special Glue for gluing the Digitizer to the LCD is about $20 by itself so that $15 Digitizer works out to ~$35-40 not to mention if you scratch or break the LCD by accident then you end up having to buy that too. I am not trying to be preachy here but trying to give you the REAL risks and obsticles associated with the repair on the N4. It is a VERY easy phone to repair in general EXCEPT the display. Just get the 3 Piece display and sell the broken one on ebay. It will sell because Professionals (who have the right tools) will grab them and refurbish them and then use them for repairs.
Take a look at this Vid, It's for the iPhone 5 but the process is the same for the N4 and N7.

Hey,
I have nexus 4. The outer glass is cracked, but lcd works perfectly. However the touch is unresponsive. If i buy just the outer glass from ebay and replaced using UV glue. Would the touch function will work? Its strange that all the other smart phones touch function work, if you break the outer glass; but on nexus 4 it stops working. looking forward to hearing your opinion. thank you.

I think the digitizer is so attached to the glass when the glass breaks it breaks the digitizer as well, hence why every n4 LCD that cracks has no touch response, the digitizer is glued to the glass and not the LCD as it is on the galaxy nexus making it a billion times easeyer to just buy a whole LCD unit

It probably is easier to replace the whole unit, however it's too expensive for some people; cheapest unit I've found runs for around 120 USD, 10 times more expensive than just the glass. Specially now that Google lowered the prices, and a 120-130 USD screen doesn't make much sense when you can have a new phone for just 199 USD.
In my case, I cracked the lower corner of the screen and the lowermost buttons don't work (ie: home, back and switch app buttons). Otherwise, the screen works perfectly.
From what I've read so far online, it's fairly hard, although not impossible, to replace just the glass on a screen such as our Nexus 4's. The main difficulty is that the LCD, digitizer (the thing that takes your finger's input, in case you're wondering –as I did– what that is) and the glass are fused together. From what I gather (I am, by no means, an expert on this... take whatever I say with a grain of salt) this means that this partes are glued together with very strong adhesive.
I haven't found any videos or guides for our Nexus, but the process should be very similar to this one for a Galaxy S3. For the time being, I resorted to just rotating my phone when I need the back and home buttons. However, when it's time to buy a new phone I'll try to replace the glass on this one.
If anyone of you guys want to try this, I hope you take a video of the process and share it with the rest of us, unlucky/clumsy Nexus 4 owners.

I also found a series of videos for galaxy nexus to replace only glass
I've found this tutorial for repairing n4 cracked screen, but I don't know if what he's replacing is only the outer glass or the whole digitizer and glass together.
vickev.com/#!/article/repair-your-cracked-lg-nexus-4-e960-screen
and by the way, did someone find the glass with the digitizer for a good price? Not considering those tricky ebay announcements of outer glass, as Ohgami_Ichiro has already alerted.
found this one, but 85,85 € is kinda expensive.

It is LCD+digitizer+glass assembly replacement. Not easiest but one of easy ways, costs about $120.

It is glass+digitizer+lcd+housing assembly.
There are also glass+digitizer+lcd+housing+battery assemblies.
If you replace the digitizer only the screen will not respond the same. My galaxy s3 has touch issues now cause I only replaced the digitizer. Now need to buy a whole assembly

Nexus 4 LG E960 Screen replacement
Well, I was pretty keen on getting a chinese glass/digitizer. The one I had in mind was on ebay.
I was a bit concerned about waiting up to 2 or 3 weeks, but I thought at £28 it would be worth it, as long as I could fit it successfully when it arrived. The alternative was £100 approx from spareslg.com. I was a little concerned about the integrity of the LCD as I was getting some "flowing" around the cracks on the glass. I thought (as was posted earlier) tha it would be no harm in trying to remove the broken glass now, and prep the what was left of the screen for the new glass. If it went well I would know that the LCD was ok. If it went badly however I would loose the opportunity to sell the second hand screen for £20 or so (also posted earlier). I decided to go ahead and strip down the phone.
Getting to the nitty gritty, I warmed up the screen with a hairdryer, inserted a pry tool between the bezel and the glass and started to loosen. I had replaced a glass on a Samsung Galaxy Ace successfully before and this procedure felt very familiar. The procedure actually felt much easier. The glass lifted away from the lcd within three or four minutes, and I continued to heat and ease the glass for only 6 or 7 more minutes. As I was raising the glass while working towards the top of the phone, I noticed that the LCD was leaving the frame as it didn't appear to be held by much, if anything. I thought I would remove what was left of the screen assembly from the frame and continue separating the two parts outside the frame. It was at this point that I noticed that the the LDC panel appeared to be dividing into two parts; like two wafers. Wishful thinking made me hope that what I was seeing was a digitizer membrane or something; but I soon resigned myself to the possibility that the LCD was history.:crying:
I didn't bother to clean off the glue residue, I reassembled the phone and switched it on. The picture below shows that the LCD was ruined. What looks like glass is in fact the movement of the pry tool on the adhesive on the LCD. No flash was used either.
The second photo shows the split LCD. The final photo shows the digitizer grid in the old glass.
If I had the same problem again, I would probably try again. I'd be particularly careful around the edges, not allow the LCD to rise out of the frame (and possibly tear) and take it much more slowly, and possibly use a wire separation tool if around.
Ohgami_Ichiro posted earlier that the costs of digitizer only repairs can go high. If you add fancy glues and tape then it would have cost me at least £50. New at £100 minus sale of old, £15 ?(so net £85) That could be £35 difference, £45 if you skipped the UV glue.
It might not be the last time this phone breaks though!! so savings may increase!
I have no choce now, £100.
Bye the way can anybody recommend a good open case, mine had barely 1.5 ml above screen edge.
Hope you've enjoyed the how NOT to.
Hi dear friends,
Sorry for late answer but i recommend you to take lcd digitizer and replace with cracked one. Becouse generally such chinese complete assemblies (lcd+digitizer and housing) are problematic as lcd quality bit lower than original one. So what to do is; to take digitizer around 20$ (there also which 10$ cost but really lower sensitive digitizer ) and replace it yourself. What else you need for this replacement?
-First you need something thin and sharp like as your grandfathers shaving blade for pry lcd and digitizer. (cost 1$ maybe)
-Then you also need glue cleaner for clean old glue particles, (costs 5$ with uv glue totally)
-uv adhesive for glue lcd with digitizer and (costs 5$ with adhesive cleaner totally)
-3m sticker for attach new digitizer to housing. (2-3$ for piece)
and totally cost max 30$. Maybe you will work more harder but at least you will get phone which which works with original screen with better view. :good:

Just i need to warn you to definitely use heating gun or hair dryer(at max. temp.) while seperate cracked digitizer from lcd. Otherwise you will crack your lcd too. With my best wishes!!!

Digitizer Touch Screen Replacement

Hello.. I had dropped my N4 and the front glass got cracked.. The LCD is fine but touch is not responsive with half of the screen. I'm planning to change just the digitizer. Since the LCD and the digitizer are fused together, we use heat to separate the digitizer from the LCD. But how to paste the replaced digitizer back to the LCD?? Should i use some adhesive tape?? or this ??
Please advise
Thanks
I think you need to use LOCA.

Glass, Digitizer, or LCD?

Dear XDA,
I have a note 3 with a cracked screen. The LDC works, but the digitizer is cracked. Now I know that there is a digitizer and an LCD and those are two different things, but now I see that there is something like glass. There is no connection from the glass to the screen, only the crystal UV glue holds it in place. Is it a digitizer with different technology? I do not want to remove the broken glass, put the glue, put the new glass, and then get no touch.
A quick answer will be very helpful, thank you!
(if the digitizer really is the glass, how does it transmit the touch senses to the phone without any connectors?)
My understanding is that the glass on top of the LCD is tantamount to a glass screen protector. If you removed the glass and touched the screen directly, it would respond to finger touches because the digitizer resides beneath the LCD.
