[Q] Screen cracked, touch not responding properly. - LG Optimus 4X HD

Hey everyone.
A few months ago I dropped my phone for the first time. It turned out that the screen had gotten a large crack down through the middle, running all the way from the top to the bottom. I tried using it, and the touch capabilities didn't seem to be affected, so basically it was just cosmetic at first.
But this afternoon, after having used it lightly since morning without issues, the phone suddenly started responding weird to touch. Whenever I touch the screen, it registers touches all over the screen, and I'm not even able to dial in my pin code after rebooting.
Does anyone have an idea what might have happened, what is broken, and how much it will set me back to fix it?
BTW, the phone arrived with a red pixel, I noticed it once when booting up, but thought it was just a bug or something. Later I found out that is actually a fault with the phone, and most companies have dead pixel policies, I'm wondering, is it possible to return the phone for a new because of the red pixel?
Thank you for your time.

I think it will be a little hard to prove that dead pixel after being cracked. If you have some skills, you can change it yourself, its not very hard and you can find the screen on the internet.

That does sound good, but aren't the glass (The outermost layer) and the touchscreen two different things entirely?
Thank you.

Well what do you know, it started working again! Well, atleast for now.
Thanks for the advice

...I'm going to go out on a limb here and say it's the huge crack down the middle of the screen? :good:
Seriously, though.. capacitive touch-screens measure changes in the resistance across a thin layer on top of the glass. So if you bend it somehow, or damage it (say, stretch it because the glass underneath cracks), then the resistance won't be picked up, or it will be registered inaccurately. So it might work for a while, or work reasonably well. Know a guy who smashed his iPhone.. sat on it, actually.. and it worked with "cracked" glass (that was held together by the layer on top of the glass, right) until he bought another iPhone. *shrug* He talked about it a lot, but it didn't seem to really make a difference on the actual phone.

Broken Diamond display, or what?

Hello there, XDA.
This thread is more for an ensurance for me that I've done nothing wrong when using my phone - and it might show up that some other people have the same problem as I do.
Now, to the thingie. Bought a HTC Diamond about 3 months ago - working just fine. Although about 3-4 weeks ago I realized that when I tilt my screen, I can see some crazy stuff going on... There is two pictures attached and linked to further down.
Anyone else has this problem? Would be lovely to hear what you've done. I sent an e-mail to HTC and the manu... manufactourer-/or~ (spelling :b).

That just looks like moisture between the screen protector and the screen itself.
Odd that it's in a perfect rectangle. I've seen this before on a mates LG Viewty (Horrible phone!), but he never followed it up so I don't know what the cause was. It did have a touch screen, but no protector. Perhaps its moisture actually in the screen or a manufacturing fault?
Good luck.
Oh my - I had rectangle on the screen today when I removed the protective front later (brand new phone).
Though It's no longer showing I'm scared its going to become more apparent and eventually become like this.
What is going on with QA and HTC?
There was another exact case like this that I saw this week. Can't really remmeber but do a search and you will find it.
I have the same thing on my Touch Pro, and another user has had the same problem on his (her?) Diamond:
http://forum.xda-developers.com/showthread.php?t=428262
Unfortunately it isn't moisture below the screen protector, but that the touch resistive layer was subject to heavy pressure (eg: being squeezed in the pocket). It shouldn't affect anything in the short term, but in the long run the touch screen might become erratic or imprecise, so you should keep an eye on it.
The store I bought my TPro from doesn't accept returns/exchanges, and so far HTC hasn't replied to my support ticket. Unfortunately I think some of us are going to be left out in the cold. Personally I'm tempted to buy a replacement touch layer and replace it myself, but of course that would void the warranty (even though it doesn't seem to be doing me any good).
If this becomes widespread, there could be a chance for a class action lawsuit (hopefully HTC will wise up and help us out before it comes to that).
Ouch >.<, feeling sad (but somewhat a bit of relief) that some others has the same problem.
Yes, the rectangular shape is very, very odd - since that makes me think that just pressure can create this mess. It feels more like a manufacturing fault.. But, as for fhsieh, HTC hasn't respond to my support ticket.
Wondering if I should call them to get a direct answer.. Hm.
I've suffered this
But in a Touch Cruise I own before. I thought, as said, that this regular shape can only came from a pressure problem.
Loosing my warranty (due to the long time to be repaired here in Spain), I opened it, confirming that was not a problem with moisture (at least in my case). Also I saw the resistive layer poorly sticked to the body, with zones unglued, causing the layer to raise, specially in the bottom edges. This bothered me a lot, because I ended with lot of dirt between the layer and the screen itself, unable to clean.
Maybe that was the problem. If the layer is not correctly assembled it gets an irregular surface (as lightly squeeshed) , yielding this. But, functionally speaking, the screen was performing well, as it should be.
Hope this helps.
It's only humidity... it happens also in my diamond... try to dry it under the sun..(not so good for lcd but it works for me)..

Yes, it's due to the prefect pressure of the screen, exactly in the center..if you try to press a corner for example near to Start button (with screen off) you should see the spot follow your finger's pressure. So there is a small drop between LCD and screen..(for me)
I had same problem in polaris. Send it for warranty as this is manufacturing fault. Why keep ****??? its htc s fault!?!
Well I thought i was the only one who had this problem till I came across this thread.... it's quite weird it's in a perfect rectangular shape anyone tried removing the protective screen and checkin whether it is the display... but one thing you hve to notice once the display is on we can't see tht on the screen only against a black background can you notice it....
It is the problem of screen protector. You may not see this watermark after you take off the screen protector. Try other good screen protector like Brando, Martin Fields ....

I tried removing the screen protector and the rectangular shape is still there then I put it in front of an A/C cooler unit and it went away!!!! then after awhile it returned back and the place I live is very hot and humid so I guess it's weather which plays a role....

Droid Bionic Water Damage

My wife rang in the new year by dropping her phone in the toilet on New Year's Eve! It took the phone, cleaned it and put it in a bag with rice and got it working again with no issues.
Since it is a company phone, they replaced it for her..no charge. So, Im left with a Bionic that is working perfectly.....except....it has dark "streaks" on the screen that are irritating and very noticeable on lighter backgrounds.
I do not think it is inside the screen, I think the phone itself is damaged from the drop in the water. Both water damage indicators are of course red but, other than the screen looking like it does..phone is operating fine other than that.
I reset it back to factory once she activated the new one and am going to add it to my account if I can either fix that screen issue or live with it.
Any idea of what steps would need to be taken in order to correct this issue? I was going to take a photo of the screen but, since I reset it back to factory, it now is just going to the "please wait, this may take a few minutes" screen since there is no active service on the phone.
Dont want to activate it yet until I see what options I have to fix the screen.
First, you can bypass activation by tapping all four corners of the Android logo screen, starting with the top left and going clockwise. That should make it a bit easier to take pictures
Second, it's possible that the damage is not to the screen itself, and that dismantling the digitizer/glass layer will make the best course of action more obvious. This is obviously only something to do if you're reasonably confident in your steady hand and don't mind the possibility of something breaking (and honestly, it was a free phone, so why not, just for the experience?) If it turns out to be, say, a stain on the inside of the digitizer layer, or residual water between the two layers, you have a pretty easy problem to fix.
iFixit has some good guides:
http://www.ifixit.com/Device/Motorola_Droid_Bionic
Good luck!
Water damage indicators can be cleared by using bleach.
Shows how much I know about this Bionic eh? I did not know I could bypass that wizard..thanks for that!
now then, this is the strangest thing, the screen issues are not what they were...they are still there but, not anywhere close to what they were. Now it is mainly in the bottom right hand corner of the screen and those are more like smudges than anything.
Very strange. Will try to post a pic once I get off work. Tried to get a decent one that shows what I am talking about now but, cant even get it to show up!
hmm, might try that as well once I get an idea if I am able to correct the screen issues, thanks!

It sounds like you have water marks between the screen and the digitizer.Its really not that difficult to tear apart a phone and clean that.I do screen repairs for friends and clients just buy the tools and then just take your time and go through the process.I'm sure by now someone will have a tutorial on youtube

[NEW POSSIBLE ISSUE] Screen Flex

DO NOT complicate this with the screen separation issue, my device does not have this issue.
When on a black screen when pressing the devices screen, it does not have to be hard just medium, the screen will flex causing the display below to ripple. It reminds me of the HTC One X screen flex issue at the top ends of the device where it was curved.
I have made a video showing my findings, I know at times it looks like I'm pressing extremely hard on the screen, I'm not its just because I was on a soft surface and so the device pushed into the bed. :angel:
Oh and your probably better watching it in full screen, just watched it embedded on here myself and it's hard to see
It's a TOUCH screen not a PRESS screen. Be gentle... you meanie!
I saw what you meant once in that video, but it did look like you pressed pretty hard. I tried to replicate it to no avail. Sorry.

I know I know, honestly though I promise you I was not pressing hard. Honest truth I noticed this issue because I held the device with one hand, and I was NOT pushing hard.
I've noticed this minor issue on mine, but on the left hand side of the screen. Doesn't bother me too much.
It probably happens because your device has the screen lift too? or the screws are loose.
As before I did the washer trick my screen also did this on the left side only, it was spongy too, once I did the washer trick it didn't do it again. :good:

Yeah I don't really see it as an issue, as long as my device works that's all I'm bothered about and I mainly use my iPad anyway.

Hmm, well the screen doesn't appear to be raised ANYWHERE and I only just got it yesterday (14th August).
My second/current one does this. But only on the left side. If you press on the black bezel around the screen on the bottom third. You'll get the ripple. Nowhere else though. And you have to press it pretty hard. It's not an issue.
No screen lift on this one. Screen lift was replaced by this ripple. That's actually how I noticed it, checking my new one for seperation, and spongy feel. Which it doesn't have.
Isn't this just a trait of LCD screens?
My One X has the same thing and has a Super LCD screen.

LCD is the screen itself, it is a trait however the bezel and glass should stop this from happening, because obviously if this happens a lot, then device is going to be damaged

Yeah. If you see ripples, you are applying excessive pressure to the screen. This is standard for any LCD, not an issue.

Well said. Not an issue.
Yeah, I'm saying that because my old laptops did the same thing when you touched the screen. Not a issue...
Phones have Glass over the screen. You don't actually touch the LCD. You have the LCD, then the digitizer, then the glass. So I think this is because the LCD is too close to the digitizer because of the screw issue. I had screen separation issues on the left side and this ripple. I made some "washers" using some medication foil packaging (3x) and not only did it fix the screen issue, but the screws are nice and tight (fixes squeaks) and pulls the screen down away from the digitizer so you don't get this effect.
Mine USED to do this (mostly on the left side) but now it doesn't after I put in those "washers". The bottom left is more sensitive still but requires lots of pressure still. If you press hard enough on the screen the LCD will still ripple.
RMA and chill.
I'm sorry but these threads are getting tiring now.

Mine is mainly on the left side as well, its actually quire hard to recreate it on the right, though its possible. I'd just like to assure readers that I am not using excessive force on the screen at all, not even close. As I said, I can recreate this just by holding the tablet with one hand!
Sent from my Nexus 7 using xda premium
wow, this has to be the biggest non issue for the nexus. it's a LCD if you press that hard of course the screen will ripple. yes the top is glass, but the nexus 7 screen uses a new process with less layers of glass to minimize thickness.
Do you have a laptop or lcd monitor? Press on the screen and see what happens.
OP you are pushing way too hard to simulate normal usage. The screen is covered in thin glass not bullet proof glass and if you push to hard it will flex and distort the black light and cause ripples.
Seriously this is a non issue.

Yeh I got ripples if pushing to hard but had the common sense to understand this is not a fault its LDC my old omnia phone does it.

Support me if your screen got dust

Hi all,
i just get back my p880 after replacement screen since the dust under the screen, but guess what?
It happened again just for 1 week.
i did write a email for them.
Hi,
I wanna make a complain on your flagship product !
last week(roughly Nov 27) i did collect a unit P880 after screen replacement due to dust under the screen. However after 1 week, it still happen again !
This is a quality issue on this unit! and i am not the only 1, my girlfriend also having same problem from day 1, and mine too.
Before sent in , i did ask your staff! your staff say no, this isnt quality issue, so far i am the only 1. i take it at that time.
But when i get back my phone, and this happened again in just 1 week !
And i did research ! i am not the only 1.

Too bad, i dont have a pro camera right now. and also hard to capture by camera.
and i believe those p880 with this issue will be more dust after certain usage.
just 1 week, there are 2 medium dot under screen. from my exp last times, about 1-2 month, there lots of dust and big 1.
really make me so sad. what a product with this stupid issue!
i have the same issue too but its really slight. the dust are hardly seen under normal usage and only when the screen is off and im looking for it.
not something very irritating but yea, it shouldn't be there. btw my Optimus One had this problem too but it was really a thick dense line of dust from the bottom left corner of the screen.

i have only one and barely notice it

i know where is it, and send before. i post here that because i believe it will happen again after second service.
previously i emailed, they said sent to their service center.
in the service center i asked,and they said no this quality issue on other p880. what i feel is nonsense, just other people lazy go for it.
And purposely go there for same problem, i am quite unhappy, because wasting my time to go and back.
And they just replace the window glass, i dont think can fix permanently, since this is a common issue for most people, wasnt?
Hello I have the same issue, in my P880 I saw specs of dust two days after of purchase, now 2 months later I have many specs, some are very annoying at sunlight. Sadly in my Country I do not have technical support from LG.

How i' fixed one dust dot.
Hello
Today i noticed white dust point between my screen and glass of phone... and.. i was pissed off!!! because phone is one month old!
Tried to calmdown ... but every time when i looked on the screen i saw nothing but that white dot...
So... i don't take any responsibility for this "tutorial" on damaging your glass or screen or phone...
So... turn off you phone ... using your pointing finger make speed hard taps on dust area with little bit bending of whole phone.
With this method i managed to move dust point from middle of screen to bottom edge of screen... and with more bending and taping on edhe area
dust spot is disappeared. (it took me 2 minutes of tapping)
I konw it sounds crazy but it worked and i'm happy again

The touch screen does not work?

A month ago I broke the outer and inner screen I ordered on eBay
I installed it and since I have a line on a screen in the upper part of the touch screen that it does not work
There is a picture but the touch is not working
I installed a few times then the problem is not with the installation
There is a possibility that I need to install the Rom again or that can not be it software problem?

in my opinion thereĀ“s something wrong with the conector besides the lcd screen.
Never ever had a problem with a rom that involving the touch function
So according to you the problem is in the internal screen in the LCD?

You think it's the LCD or external screen?
I can say that it's the sealing rubber's fault out of bad experience, because I replaced my screen myself recently.
After first ordering a replacement screen and installing it properly my whole upper half of the touch did not work. A second time a smaller fragment did not work.
After googling it, I found out that the sealing rubber around is very important, however even though getting a rep. screen is no problem at all, getting the rubber was impossible on ebay or on any local shop. (Why is no one offering these?)
So I ended up buying the thinnest double sided tape I could get and everything works fine now. It's extremely fumbly though and takes some steady hands Use a knife and not scissors to cut the tape.
