Recently I added a screen protector to my Alpine, and after that the screen started acting funny any time it was left alone. Removing the screen protector has made no difference.
After a short while of not being used, the screen becomes misaligned, for example if I leave it off for an hour, attempting to activate the start menu on the today screen will result in one of the today items being pushed, or attempting to select a number on the password entry will result in a different number being pressed.
The strange thing is I can re-align the screen through the control panel, but it will slowly go back to the way it was.
Anyone got any thoughts? At worst, I'll just refund it (I bought it where I work, and thats no problem) and get another handset, but if theres a fix I'd prefer to stick with my current handset.
Cheers in advance for any help!
I am not sure about this, but I had the same problem with Motorola A1000 touch screen - could it be that an excessive pressure was applied to one of the sides of the digitizer during the application of screen protector? The digitizer is glued on the LCD, there might be a remote chance that it has slid a little to one side. Also some extra glue could have shortened the contacts on the bottom part of the digitizer. I would try to clean it first with some anti-static liquid. Hope this helps..
Indeed, this sounds like there could be more pressure to one side of the screen than the other, hence the digitiser tries to adjust for the pressure difference and gradually falls out of sync.
Try reapplying your screen protector, more gently than last time if possible, but don't wipe from side to side, wipe from top to bottom with an even pressure. Also, try realigning the screen with the protector off before reapplying it.
I had a problem with my screen originally before I got my screen protector, insofar as I got that 'rainbow' pooling effect in the centre of the screen where the digitiser was touching the LCD layer - after about a week after application of the screen protector, however, the more even layer of tension provided by the protector somehow pulled the digitiser away from the LCD layer, so my screen has actually gotten better since then... That said, I could imagine that uneven tension on the top layer could lift the LCD and digitiser layers further away from each other on one side than on the other, causing the problem you describe here. If you can bear to, try using the phone for a couple of days without the protective top layer applied, and see if the alignment gradually slips out as it's doing at the moment.
I've been using the phone for the past two days without the protective cover on. I'm going to reapply it now and then see how it goes tomorrow. If its still screwed, I'll reflash it to the O2 ROM and refund it at work on Tuesday.
Got a replacement, so no problem now. Thanks for the help anyhow
This is something i noticed with my device, the screen protector iv had it on ever since i got my mda vario III, today i removed it cose there was dust collecting at the edges of the screen where it couldn't reach as its smaller than the screen then i notice the device was performing alot faster to make sure i wasn't just seeing things i tried playing a game of FPSEce before all were really slow average 10fps when actually playing now i get it around 20fps the game was actually playable not perfectly of course but still alot better. Again this is a possible effect of the lack of drivers if we get screen protector companies on your side who knows i mean who would buy one if it slowed down their ppc which would lower their business.
Lol , the only conclusion i can give you is that your screen protector was actually continuously pushing the touch screen somewhere.
Resulting in the ever lasting htc touchscreen driver bug eating cpu cycles.
You can always check this with an app that shows cpu usage.

Batterystatus used to show it as low
The screenprotector does not weigh enough to be able to create a force large enough to activate the screen.
Here is a different theory: the screen protector does not let heat to diffuse through the screen, outside. Hence, the device become warmer, and the CPU throttle down...

It does if it goes under an edge... my touch stopped working, cause it got slipped under the edge and therefore was exerting force on the screen.
this is impossible because our screens are only single touch, if it was always being pressed then that means the press from out finger or stylus wouldnt work or it wouldnt press most of the time. you would find it very messed up. havnt u ever tried pressing in 2 places on the screen with a paint program or drawing just for fun?
i could see the screen protector "pressing" on the screen if it was stretched or shrunken.
however, have you ever taken a ball point pen and tried to write on a stack of papers? you eneded up with a clear "dent" on the second page, but a barely visible "dent on the third. the screen protectors make the screen less sensitive because it's just another layer. try doubling the sensitivity in your registry from 7000 to 14000 and see if it helps a little. (or the oil from your skin will eventualy collect enough dust, that if you do any heavy literary work on your PPC; you will surely wear out your screen)
I have a couple of light scratches on my screen from drawing; so i prefer the screen is less exact, but protected.
(keep in mind you create friction when you run plastic on plastic; and friction creates heat, brazing the tip of your stilus, ocasionaly making it sharper than it should be.)
I suppose thats how I see it.
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.

I have the same problema with my Diamond2. I have also changed the digitalizer with no success It is still not responding to any kind of touch.
Shoofty, did you manage to fix yours?
Thanks in advance,

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
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.
