Hi
can anybody tell me how to resolve that problem ??
Unfortunately I had the habbit of keeping my phone in my jeans butt pocket, even when I switched to Diamond touch screened phone I kept doing that, but I realized that the screen got some slight concavity on it that even reflects as irregular pattern of colors seen only when screen switched off or when on but from a sharp viewing angle.
How to correct that ??? any ideas ???
Thanks
Replace the screen.
Change phone carrying habits.
It is a hardware issue, so not easy to fix. Beware that the screen is multi layered (touch screen) so it is possible that any physical shape alterations will seriously change the way it works. It happens that screens go weird when there's dust & debris between screen and the outside body of the phone...
Thanks for your reply
Is it worth it to replace the screen ?? or maybe its better off selling it for less cash then buy another one ?
I have noticed that there is a matrix of visible small dots 2 mm apart from each other, I guess this is the touch-sensing system.
Yeah, the touch-sensitive layer got squished. It should still work fine for now, but over time the touch sensitivity may get worse. The only way to fix it is to get it replaced. If it's still under warranty you should replace it that way, better than selling and buying a completely new Diamond. If not, you can replace it yourself with this: http://mobile.brando.com.hk/prod_detail.php?prod_id=03449&dept_id=088&cat_id=0695
Thanks fhsieh for the info and link.
I will replace it when it fails eventually, now I am releaved and I know that I've got a solution
hi,
my touch diamond 2's touch screen stop working randomly ( i think that i applied too much pressure on 1 spot for too long). I can see the touch screen dots on the area. I am just wondering if I were to repair this, would i be replacing the DIGITIZER or the TOUCH SCREEN.
Thank you soo much
warranty might cover that. It might not be your fault
I have decided to fix the part myself since I do not wish to ship the part to their location in the US. Any idea if its the digitizer or the LCD screen that i should be replacing?

Search the Wiki, there are dismantle instructions.
I had the same on my display, and was able to move the dark spot to the edges where it disappeared.
I moved it with scratching it with my nail very gently applying some pressure.
In Europe HTC offers a pickup and return warranty, is that different in the US? If it is the same I would send it in to HTC for replacement, since it might happen again pretty soon....
I already have 3 screens replaced :-(
jason, did u manage to fix this? i have the exact same problem and pushing the "bubbles" towards the edge of the screen didn't help. my screen is still unresponsive..

Try applying duct tape to it repeatedly until you get it back.
Yes, both
I recently replaced the Touch Screen on my Diamond 2. Same problem; spots that "stick" in the middle. I used to solve this by running both my thumbs down the sides of the screen to "puff up" the low areas in the middle.
The part you want is actually called a "Digitizer Touch Screen" on eBay, cheap too. Prepare to spend about 2 hours fiddling with very tiny screws, connections and glue to tackle the job.
The hardest part for me was actually getting the Touch Screen to work; it seemed to be calibrated in mirror-image AND turned 90 degrees sideways, which made getting to the calibration functionality an extremely frustrating experience. I spend another 3 hours on that, but now I've got a perfect phone again, since I ordered a new case as well. No use taking the entire phone apart and then rebuilding with a molested outer shell...
maybe you should reset it
Working Solution Till Now
Hello Friends,
I have TD2 mobile and today I had same issue. I was thinking it was because of the weather or some.
I remember it did happend several time before, but when I restart the device several time it does work. So I was ignoring.... But today it did not work.. looks like going toward end... So I did soft and hard reset without and that did not helped me.
So I switched off the mobile, "heated" the touch screen gently with my hand for 1 min and started the mobile again and it worked for me .
Not sure if this is a solution, but will work.
May be I will contact Service Center here in Hyderbad and see what is wrong here?
Hope this will help you all...
Thanks.
Solution
Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!
Digitizer replaced but still not working
The touch screen on my Touch Diamond2 stopped responding to my touch (or the stylus) and I tried everything including removing and replacing the digitizer bus just in case the connection was the issue. But all to no avail. Finally I decided to replace the digitizer (touch screen)
The problem for me is that it made no difference. The new digitizer doesn't respond to my touch either. The problem is apparently somewhere else.
If anyone has encountered this problem and has a solution I would be grateful to know what it is.
Thanks in advance
Replace the Touch Diamond2 Digitizer touch screen.
I recently replaced the digitizer (touch screen) on my HTC Touch Diamond2. Since I found on the net, no instructions for replacing the actual digitizer, I thought I might include some here.
It was relatively easy to fit. The only difficulty I encountered was a lack of information about how to actually remove the old one. The various instruction sets found on the web all stop once the screen is removed. But the digitizer is not covered by these instructions. The digitizer is bonded to a thin glass immediately under your screen protector (if you have one fitted) and after the screen is removed following instructions you will find on the net, the digitizer and the thin glass sheet that it is bonded to must be prized off from the front of the housing. The digitizer separates from the glass easily, but the glass is securely bonded to the housing with a silicon glue. It must be prized off by gently lifting a corner and applying a little upward pressure allowing the glue to slowly and gently let go. Don't be surprised if the glass breaks during the process. Once off it is a simple matter to press the new one in place. Just remember to start by slipping the connector bus (cable) through the narrow slot between the metal outer housing and the inner components. I used a set of tweezers to poke it through. DO IT FIRST before pressing the digitizer into place.
Okay, as I said the process was easy and took about 15 minutes all up.

Thanks for the heads up on the glass part mate. Just replaced my TD2 digitizer too. Kinda freaked out at first when the glass split.. haha
Anyway, just wanna 1 more info. When removing the old digitizer, it'll be easier if the front housing was heated first (with a hairdryer on full or a heatgun) to soften the glue. It'll be easier to remove afterwards.
Word of warning though. Only head the housing when REMOVING the old digitizer, DO NOT use this method when applying the new one. The digitizer dies because of heat. Heat is what causes the newton rings issue.

Shoofty, did you manage to fix yours?

Fixing TD2 touch screen
TD2 touch screen is a common problem I guess.
Symptoms are :
1- Touch screen does not respond sometimes
2- You can see a grease like layer under the touch screen
3- Sometimes if you look closer to the screen at some part you can see a a liquidized small area.
Solutions:
1- If you see the liquidized dot on the screen turn off the display and try to rub it with your finger until it disappears. turn it on again and try if it works. I guess heating with the finger as other peeople here suggest does the same thing. However this is a temporary solution. Your touchscreen will die at some date. I used my TD2 for 8-9 months using this method. But at the end touchscreen died.
2- Replace the digitzer or complete frontcover. Actually this might be easier than you think. I replaced mine in half an hour. I bought a front cover which includes the digitzer (http://www.ebay.de/itm/Original-HTC...zer_Ersatzteile_Werkzeuge&hash=item4cfe6f78dc) and openning tools from ebay. Dimanıond 2 disassemble and assemble videos on youtube were very helpful. I strongly suggest to buy the complete frontcover (inc digitzer). It makes replace process much easier and gives the device a brand new look. My old front cover was worn from the corners (which is also very commpn problem of TD2). Now it looks brand new. No strach on the display and body.
Thnks Ozkarah.
I happened to realize that, surprisingly, the touch screen of my HD2 started working if I heated it up with a hairdryer. So, I think something else is wrong beyond the touch screen, probably the connector to the main board of the mobile. It might expand once it is hot and that is why it starts working. In any case, I think that is beyond repair

Hi,
I have same problem when I changed new screen (screen is calibrated in mirror-image AND turned 90 degrees sideways).
Could tell step by step how you get your screen calibrated?
Thanks
My Droid's touch screen isn't working in the center vertically all the way down. I can still use the 'edges' of the screen. I need to use the middle of the screen for a few things (not transfering stuff over). Is there any way I can 'project' my Droids screen to my computer and click/touch in it to use it?
Thanks in advance for all help. It's appreciated

Edit: This is the original Motorola Droid.
I have the same problem on the right side of my milestone :S
I had the same problem, but from the back arrow upwards, specially when the phone got hot. As my phone was still on the warranty period, I flashed it back to stock and updated it to the official 2.2., took it to an Orange shop and got it back after almost a month: they basically changed the whole top part of the phone (I got a brand new screen )
Repair problem
I had a same failure. The touch panel was bad. I ordered one from eBay. It also came as well put it. It works well. Only so much wrong with me that for some reason the phone stacked in landscape mode, I can't change to portrait mode. What is wrong? I put together something wrong? I do not think so. Everything else goes. (or so it seems)
This has to do with the digitizer (the glass you touch over the top of the LCD you see) being defective or unsealed. This is due to environmental moisture finding its way into the phone and f**king with the electrictal signals sent by touching the screen. There is a 'phantom touch' issue that seems to happen before or during the vertical unresponsiveness, and that can usually be temporarily remedied by firmly pushing your screen downwards (your phone may restart) and taking a blowdryer to your phone until it's just hot enough to be uncomfortable to hold (and no longer take it into the bathroom while you shower). One way or another, you're going to have to replace your digitizer eventually.
Sent from my Droid using XDA App
I had the same problem months ago but it's now fixed.
STEPS:
1. Digitizer I bought from this guy:
http://cgi.ebay.ph/New-Touch-Screen-Digitizer-Motorola-Milestone-A853-/270780531 891?pt=UK_Replacement_Parts_Tools&hash=item3f0bc704b3#ht_2811wt_850
2. Dissasembly Videos (I advice you to watch them repeatedly before dissasembly):
http://www.youtube.com/watch?v=6d7ETMfgq2s
http://www.youtube.com/watch?v=dE81IaQHEHc
3. Phillips screw driver( for dealing with hard screws around the screen): Because I don't want you to use the low quality screw driver supplied with the digitizer.
4. Double sided tape: I got mine from a hardware shop for only P19. Buy a the more expensive tape(P100+) but look for a very thin one! You will use the cheap weak tape to stick some internal parts and use the Hard tape to stick the external casing. EDIT: I just used the cheap one for everything and it's strong enough.
5. PATIENCE: Don't be in a hurry. I even paused from time to time to get a better idea about what to do next. Get the feel of being a perfectionist (that same additude when I applied a screen protector )
That's the guide from me who haven't dissasembled a phone in my entire life but my milestone. So if something bad and technical that happens along the way then my knowledge can't help.. sorry.
Good luck bro!!
So my phone cracked up today(rip) while I was doing some gym exercises. The phone fell from like 1.5 metter or so and the screen cracked.
The problem is that screen won't turn on, even when the phone looks like it works. I tried to furce shut down and turn it on and back and recents buttons work, but screen while stay black. What should I do? I will replace the screen but I'm not sure why screen won't show up, maybe something got disconected with the fell? Does anyone has any type of experience with this?

So, your screen is broken, and you need to have it repaired, what is the problem? Some parts still working?
Just get it fixed...

I really don't know why you asked this question, but I always try to be helpful. Since you did drop it, and from such a height (do you like keep your phone in your pocket while doing pull-ups? Mine's always in my bag and I use BT earphones).
Since your screen is cracked, and that impact could've damaged your phone in many ways.
1. You could've damaged your digitizer, which is a screen replacement situation
2. You bent a cable from your screen to something else, and that may be the issue, still would need to replace the screen.
Your buttons working have no relativity with the screen not working, it works with other hardware not interacting with your screen.
Don't go for third-party screen replacements that "fixes your digitizer seperate from the touch", it mostly doesn't work, and it'll be a waste of money, if you bought it from OP Store, just RMA it, or if you bought it from a seller in your country, just order the screen off eBay, and have it fixed. Your shop will most likely replace it with a non original screen, which will be horrible.
Cheers!
I think he is confused about the glass versus the AMOLED panel. A lot of times, you see folks with broken glass, but the screen still works (still displays graphics) and he is wondering why that isn't the case. At least, that is how I'm interpreting the question.
The answer is that the "screen" is composed of layers. The top layer is the glass (which for Super AMOLED also incorporates the touch panel or digitizer) and below that is the AMOLED which actually displays the graphics.
Since the glass is broken, and the AMOLED is not working, it's possible (or even likely) that the AMOLED was also broken in the impact. Yes, it's also possible that a connector has come loose. But from what I'm reading, it's actually common for the AMOLED to break before Gorilla Glass does: http://www.gophermods.com/amoled-vs-lcd-tale-two-screens/
A lot of times when you see folks with glass broken, but everything (touch and graphics) still work, it may be with LCD screens; which are supposedly more durable (more possible for glass to break before the LCD).
I only got this phone couple of days back and I am having a strange problem.
After installing a screen guard, touch stops working when phone is lying on flat surface. Once I lift the phone, touch starts working again. This happens regardless of the phone is plugged or not in a power socket.
Removing screen guard resolves this issue. However, I installed three different screen guards of glass, plastic and rubber types and with each type touch stops working on a flat surface.
I also did a factory reset but it didn't help. I tried with case on and off but the problem still persists.
At this point I am clueless how to resolve this issue as the phone doesn't seem to be defective as touch works flawlessly without a screen guard.
Same here!
With glass screen protector I have this issue... Can't really use it while device lying on a table.
Hi... Same here also... I thought the screen problem but not even lying on the table but when in charging lying on the table also can't touch... And sometimes it's stuck when to touch... My nokia 6 i think also like that... Maybe the screen curve is??
I have screen protector bought from Taobao, no such problem on my Nokia 8, TA-1004.
The screen protector is not glass type, but looks like plastic type.
Another strange observation: If I plug headphone jack when the phone is lying on flat surface, touch starts working again.
I suspect this entire thing has to do with metal/glass body of the phone and static electricity generated or magnetic field around touch panel.
I don't have much knowledge on this type of scientific stuff so I am not sure what the problem is.
It's the cheap glass protector and its glue that is messing up the touch screen.

I thought so. But what about headphone jack fixing touch issues with screen protector on?
Also, I have used similar quality screen guards on Moto and Huawei phones at my home and they don't have this issue.

Are you connecting it to headphones or speakers?
Maybe the capacitive buttons doesn't like the glue and messes up everything? You could try enabling these in the Developer Options: Show taps & Pointer location. Let me know what is happening

Headphones.
Enabled taps and pointer location. When phone is not touching a flat surface everything works fine. A curve is drawn on screen showing various gestures and a circle is drawn to show taps.
When lying on flat surface, if I use any touch gestures (e.g. scrolling) curve is drawn once in 5-6 attempts. Same with taps, circles appear only once in a while.
It is all very erratic. When I repeatedely try to tap anything, I receive ghost touces at a different part of screen.
Just noticed that I don't need headphone jack to fix touch. Blocking 3.5 mm port with one finger also works. This is truly getting weird.
Have you shown it to the Service Centre? Do they have any theories?
Sent from my Pixel 2 XL using XDA-Developers Legacy app
No, since the phone works perfectly without screen guard, I think service center guys will simply tell me to use it without a screen guard.
But I will indeed show them this problem after few days, though I am not sure they will understand or will be helpful in this regard.
I think I am reaching somewhere. The antenna reception at the top might be messing with touch.
What I have observed that touching the top of the phone or keeping any object or my hand one inch away from top of the phone fixes touch issues.
If I remove the object or move it farther than one inch, touch becomes messy again.
If I put little pressure on bottom chin of the phone, the top of the phone raises a bit so that the top antenna is not close to flat surface any more. This also fixes touch issues. Lowering top part of the phone brings back touch issues.
Anyone else with this issue can test this?
This video exactly describes my issue:
I found that many phones had these issues in past including oneplus, lg, sony and galaxy phones. Everywhere it was mentioned that it is a grounding issue which is unfortunately a hardware detect.
My phone is fortunately within replacement window. So I will contact the seller and request for a replacement.
I was thinking about the grounding, but when you mentioned you used headphones i thought it couldn't be the case.
Keep us updated if you get it replaced.
Just received the replacement. Same problem on the new one
I don't know what to do now. No other phones in my family have this problem and that includes $200 budget devices. This is flagship and much more costly.
I will just summarize different cases in which the touch issues on a flat surface gets fixed on my device:
- Inserting headphone jack (with screen gaurd applied on display).
- Inserting charging cable (with screen guard applied on display).
- Touching any part of the phone with finger including blocking the headphone jack (with screen guard applied).
- Removing the screen guard.
I am tired of this sh*t. I have tried all things possible to fix it. I have also wasted money on 6 different screen guards to fix this issue.
Some guys on galaxy s8 forums mentioned that modern curved phones uses a touchscreen placement mechanism different than traditional smartphones (they were also having the same problem).
There were two possible solutions mentioned:
Find a screen guard that has glue all over, not just around the edges or at dots. Which means that screen guard should stick to the screen 100% flat without any gap, air or bubbles.
Second solution was to use a flip cover to protect the screen and no screen guard.
I will go with second solution and buy a flip cover. I simply have no energy left to hunt for screen guards that work properly on Nokia 8. Not to say that you will never know if it works or not unless you purchase it and stick on your phone.
Hi, I'm writing from Italy and I've the same problem, exactly the same problem, solvable with the same solutions you have proposed: remove the protective film (a glass screen guard in my case).
I'm noticing that the touch screen works perfectly with the protective film only if the phone is connected via USB cable to the battery charger or to the pc.
