Is my touchscreen original? - LG Optimus 4X HD

I was wondering if my touchscreen is original, surface scratches quite easily, only two points are being recognized and when i touch one point, the recognized point is jittering around, see yt video: watch?v=tZNAQmrlqVU. Besides that, about half the time it doesnt react on certain parts (always other ones) of the screen which can be "fixed" with some loving pressure, but its very short lived.
I am asking, because i am gonna buy a new touchscreen and want to make sure its not such low quality again.

Thanks for everyone at least reading my post. Today i received my on good luck buy and got what i needed, fully functional touchscreen.

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....

Does your Diamond feature Newton's rings?

I am currently really interested in a Diamond, however the thread Oily liquid underneath screen - from nowhere kinda make me reconsidering it. Because of that I contacted HTC and received a surprisingly quick reply, stating that nearly every device sent in had a physical damage
Dear Sir, I can confirm that this fault is normally caused by physical damage to the device. Nearly every single device we have repaired with this fault has had some form of physical damage that has led to the fault. Of course the few that haven't were repaired under warranty. I quote directly from our repair centre: This issue is caused by air/liquid entering the LCD layer, and is nearly always OOW (Out Of Warranty) as it can only be caused by excess pressure on the screen. As long as you look after the device, and take care of it, this issue is unlikely to affect you. We have numerous Touch Dimonds here in our support centre, around 3 or 4 for each language we support, and not one of them have displayed this issue.

Today I took a look at some models on display in several stores and except for one all showed the same effect described in this thread. However I have to admit that this might not be the perfect example for a comparison as those poor phones probably not get treated extremely well in stores.
So I hope to find out with this poll how many people really have got this issue, respectively how many of them can explain it with too much pressure.
Thanks everyone.
I had exactly the same problem. Just went back to T-Mobile Netherlands, and they admitted directly that this is a common issue. They repaired it under warranty conditions at no fee at all. They just replaced the entire screen and luckily I've never faced the problem again.
Also, when the oilish liquid was there, the screen alignment was always a little outlined, and when you tap the slylus on that spot you can hear a strange hard "click".
Thanks to all voters, so far all voted to have no problems, except for one, I suppose peponline.
More opinions/votes appreciated.
I've got it on my 7 month old diamond - screen works ok, but tapping it isn't soft like it used to be. Not a bad enough problem to send it back and be without a phone for a couple of weeks, or risk being charged for!
Thanks for your post Alpsp, did it happen for no reason or did you do touch the screen once too hard?
Those who voted the third option, are you definitely sure it couldnt have come from too much pressure - maybe unnoticed in the pockets?
More comments/votes appreciated.
Hi Lutent, I can honestly say I don't believe I've put any abnormal amount of pressure on the screen - I'm pretty careful with the phone, it doesn't have a single scratch on it yet.
What is strange though, is that I've just tried to take a photo of the liquid for you, but it has completely disapppeared!
The only reason I can think of for this is that it hasn't been in my pocket all morning so will be cooler than usual. Also it doesn't show up so much in daylight - I'll have a look later tonight and see if I can photograph it
Hi all
I have the same issue. mine covers 50 % of the screen.
Whats funny is that its exactly right smack in the middle of the screen
its like a zoom box of the screen.
It appeared suddenly and all my touch screen alignments runs as well.
didnt have time to send for warranty until recently.
have sent it in now currently waiting for repairs to complete.
so far no news about if its OOW
smudge
Had this problem for some short time, the touchscreen has become hard to handle, as it's not very precise in the area of the "liquid spot", covering 1/9 of the center of the screen. Have no clue of where it came from.
Just sent an mail to the store, demanding replacement refering to this as a common problem after doing some reseach at different forums online.
Waiting for reply. Will notify the results.
Same problem with my HTC Fuze. It looked perfect. Never dropped. Made call. Looked good. Pulled it out 5 minutes later...the square was there. (I had just flown from Atlanta to LAX...I wonder if atmosphere had anything to do with it???)
Definitly a defect in design.
PS...The letter they sent is BS. It's not the LCD but the touchscreen. The touchscreen is touching the LCD...in my case anyway.
You will probably also notice a slight curvature of the touchscreen down toward the LCD if you look closely.
The reason they don't want to repair them is because this is the most time consuming repair. The phone has to be completely disassembled to attach the cable.
I am really pissed. i had liquid under the display just two days after I bought it.
I am super careful with all my electronic devices and not once did I have to send in any device to get it repaired.
the D2 was also always in the leather pouch.
For some reason, initially the oily liquid disappeared and I could keep on using it, however not it is there permanently and when I called the warranty place, they said that most likely I will have to pay for the repair as displays are not covered by warranty.
I am really pissed and would recommend buying a different phone. Sooner or late I bet everyone will have this problem. It happened to me after just two days, I can not imagine it to last 2 years or so...
Sigh... same issue here. I just bought a TP from a good friend of mine who is exceptionally carefull with his phones and I've just noticed a big part of the screen (1/4) being full with the Newton Rings.

Dust under the screen

So there is now a piece of dust under screen in the lower right corner a couple of centimeters from the right and bottom edge. Actually there is one tiny and one a bit larger. I've tried knocking it to see if it will move, but it's completely stuck. It's really visible no matter if the screen is on or off, inside or outside in the sun. F-ing annoying!
Anyone else?
I got the phone four days ago so I'll be returning it promptly if the reseller won't agree to swap it for a new one. (We have a 14 day return, no questions asked, policy for web orders in Norway). In my experience, dust under the screen never goes away and just gets worse over time. My old 1st gen PSP is filled with dust, but my Nexus One is over a year old and the screen still looks brand new.
Maybe you could snap a picture to give us a better look? I might reconsider buying a G2x if this becomes a common occurrence.
seems like you get defected one bare brukk angrerettuse your rights i mean
It doesn't seem to be common, as I've seen no other reports of it. There is however a certain percentage of all electronics devices that get issues like these, so it's not unheard of.
I have now found more dust particles on the screen, so the seal seems to be leaking badly. Even though I rooted it etc., we now have nvflash working, so no problem.
Could you provide us with a pic of your display?
Don't delay; report & return it ASAP. I had some dust in my PSP & received a new model right away.
Picture of the dust: http://dl.dropbox.com/u/1611645/xda/O2X_dust.JPG
It was dang near impossible to get a good shot, but I think it's showing of the dust nicely. However it's impossible to tell from the photo if it's over or under the screen, but the screen is completely clean.
Good news! I got my phone recognized as DOA, and a new one is on its way.
I have a OCD about the dust issue but it's very difficult not have any spot of dust under screen (and drive me nuts!!) but...most of electronics devices have this problem. My Galaxy S, Milestone, etc too.

"Ghost touches" and screen protector?

So, my current XT720 started having episodes of that dreaded "ghost touches" insanity two weeks ago with escalating frequency. Last week it started to happen roughly every two hours. I found that wiping the screen off on my shirt would help for a few minutes, but I just assumed placebo effect (somewhere I had read that the ghost touch problem results from ground wires coming loose--so I was contemplating disassembling and reassembling--except I can never get that stupid "8.0 xenon" sticker to come off cleanly in the past so I was holding off). On a whim I googled a bit and found on a droid forum that someone was claiming that cleaning the screen with an electronic wipe solution solved the problem but that success can depend on which cleaning solution was used. I was skeptical, but I had a pack of Windex electronics wipes so I figured "try it"... the ghost touches disappeared immediately and have not returned (it's been 5 days). So, clearly some sort of residue on the screen was responsible.
So that got me thinking. I'm currently using an XT720 I got used that came without a screen protector (My wife is using my original one that has a zagg invisible shield since day one and has never had a ghost touch problem). When I got my current one, I debated whether or not to install a screen protector and decided to give it a shot without (which is really nice by the way--the screen does not scratch even when you forget and drop your keys in the same pocket--but it does develop get a weird patina which is what the cleaning seems to have removed--the zagg has a nice feel to it, but it's got a strange uneven surface that takes some getting used to, so the shield-free experience was a nice change for the fingers--my only objections were that sometimes it seemed way to sensitive to touch and that the bevel edges around the screen feel too recessed so the design seems to anticipate that a screen protector is installed).
So, my question is: I can hand-wave an explanation that a conductive/capacitive membrane develops on the surface of the screen and interferes with normal operation of the digitizer. And that perhaps a screen protector counteracts this either by keeping whatever this conductive/capacitive residue is slightly further from the digitizer or possibly by preventing generation of this residue due to different surface properties. Have people had the ghost touch problem with screen protectors?
I can t really help you i never try any screen protection
But i had ghost touches but not at all like yours it happened 5times max(in 2years of heavy use) i think and always when it was raining when my screen get a little wet... and it stop maybe 5min after drying the screen
Never got it with out rain...
Same for me... the phone start to open apps alone jaja xD
Sent from my XT720 using XDA App
I've had the ghost touch problem twice now, both with screen protectors. The first time was with the screen protector that came with my Otterbox and the second was with the protective film that comes with the phone new (it worked fine to my surprise). Each time, it happened about 6 months after receiving the phone. However, I've not tried the electronic wipe solution nor any physical disassemble/reassemble operations.
BTW...my previous thread about this: http://forum.xda-developers.com/showthread.php?t=1102074
Hm, seems like what's actually happened is that the left-most strip of the screen doesn't respond to touch at all anymore. I just found it's difficult to type "q" and "1" So, probably the ghost touching was while that element was dying. It's still mostly usable (I can get the q and 1 by slowly moving my finger from the edge). If it gets worse I'll have to think about repair, I guess. I see the glass is available from ebay and I've also amassed a few for-parts XT720s so I've been looking into what's involved in replacing the digitizer but I can't figure out how to remove the front glass from the chrome frame...

Hello guys,
I had these "ghost touches" until two weeks ago. Then, I installed a screen protector and had no problems at all later. I am not an expert of touch technology, but I assumed that putting something between the dirty and the screen would help, and I can say I was right so far
Ah, just one note: just before applying the screen protector, be sure to clean perfectly the screen, otherwise it will not counteract the problem (use for example an electrostatic "cleaner" and a properly clean cloth).
Hope this helps!

How to make sure that the screen is dead

I put my phone to charge before sleeping yesterday, when i woke up, i unlocked the screen and phone was charged fully,
Suddenly after 3 or 4 seconds my screen went black! but i still can hear touch sounds, my computer recognizes the phone storage and i can feel the vibration when i turn it on or off.
I've also tried wiping and flashing a stock ftf through flashtool, nothing.
So my guess is the screen is completely dead and i will be replacing it shortly but before
is there any way to make sure that the problem is with the touch panel only? so it's not related to the motherboard or any other component?
To make sure that screen is dead use hammer or other heavy and hard object.
You need to place it on the screen with good amount of speed to get give this object more power.
I would recommend dropping it in the middle of the screen so you could be sure that screen is dead.
Im not recommending using car or dropping it from high, because there is a chance that you would kill not only screen but also other components of the phone.

That's not funny at all.
Well... when I saw this title I could not resist...
But to be on topic. If fresh flash dont help, there is no "software" way to check if screen is dead for sure.
XZ construction is tight as hell, and only way to fix screen is replace it in service center OR make it by yourself.
On aliexpress you can buy XZ screen for less than 25 euro
http://www.aliexpress.com/item/Orig...LCD-Screen-With-Touch-display/1894781909.html
http://www.aliexpress.com/item/Blac...Z-L36h-L36i-C6606-C6603-C6602/1901021035.html
Its not much, and if you played a bit with phones before its gonna take you less than 30min.
I ordered screens from ali few times, for my old Xperia Arc S and Neo V. no problem still work like new.
But because you need to remove back panel, I would recommend buying it too, its less than 7 euro for panel with NFC antena
You get all tools with it, and only what you need it hair dryer or wet towel that you put in microwave. Its necessary to unglue back panel.
PS. I know that it sound weird, but one time when I have Galaxy S and screen was dead... I throw it ""by accident"" on the ground... and its start working xD Im not saying that you should throw it... but you know... ""shake that baby""

I was already considering the "shake that baby method", it might be just a problem with some inner connection or cable or something.
That's why i was asking if there's is a method to make sure that the screen is completely dead, so i might not need to replace the whole panel.
And about the replacements, i read some reviews on similar products on amazon, most are complaining that they started to see blurry text, lower brightness, microphone not working and alot of other problems, you seem exprerienced with the procedure of repairing so what do you think?
Well, in terms of changing screens I bought screens only for Xperia Arc S and Neo V If we talk about smartphones :]
I speed almost whole day looking for it on eBay and Aliexpress. Of course before that I checked professional shops and local services, but its F hilarious that they want even 150% of phone price JUST FOR SCREEN....
I always sort list by number of orders, so I have chance to read more comments, and most of this time I spend reading them. If I found even single comment that say that quality is bad... I checked next one. And after few hours I had 2-3 screens to choose.
And in terms of quality... its hard to tell, most of problems are made by person who put that screen in phone, not screen it self. And because as I said build quality of new phones are tight as hell, 0.5mm difference and something is not working.
But overall quality of those screens that I had where good. I didnt had problem with brightness, ghosting(in moving object) or blurry text. I only had problem with less saturated colors. Difference is not huge, but if you spend with phone some time you see that its about 10-15% less saturated.
To be honest with buying something online that is more complex than brick and it contain electronic components its always hit and miss...
I could had luck with screen, someone could not have... Normally I trust online shops, but its better to spend whole day in front of PC than buying first product from the list...
In terms of actual replacement, instead of inventing wheel again, just check YT videos, watch few of them, and if they have link in description for screen, check them, sometimes they give link to screen that doesnt cost fortune and you know that you can get good quality product.
here are few of them:

Just remember to prepare everything, flat place for work, all tools, and few cups or bowls for parts... flat table or not, Its better to keep all screws in bowl :]

Thank you for your help
last thing
what do you think of this http://www.aliexpress.com/item/Blac...ame-Assembly-Replacement-Part/1449119790.html
This look a bit average looking at comments, most of problems are with dead pixels.
Weird that for XZ screens there are less offers that I would though :/
I found this one that look promising:
http://www.aliexpress.com/item/For-...6601-LCD-display-touch-screen/1902384532.html
and if you want whole front panel
http://www.aliexpress.com/item/For-...e-Assembly-Black-Replacement/32279043240.html
But as I said its hard to tell if you get screen without problems... I would say to check eBay or Amazon, but to be honest its all from the same place so what the difference?
