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
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?
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 am running the latest a stock debloated 6.0 rom from tupac4u right now and having some issue during phone calls. For me I make or receive a call and my display will turn off even before putting the phone to my face. However, getting the screen on during a call is a bit hard to do as pressing the power button doesn't turn the screen on(sometimes have to press it 3 times to get it on). Anyway to fix this, or to disable this? Thank you
Using a screen protector? If yes, it may be blocking the proximity sensor, which is located just to the left of the top speaker grill.
In another thread I'm being told it's a bug with marshmallow. How accurate is that? And yes I am using a screen protector. I'm just not sure where the proximity sensor is so I can adjust accordingly?

I do not use shell or film and have the problem for a long time. Tried everything but nothing helps you get used to it.
Knowing isuses since 5.1 and the sensor is on the top left of the earpiece
Yeah i took a light to find where it was. I have a tempered protector. Tried to use a knife to adjust it, but broke the screen protector. Oh well I'll just skip one cup of tea this week. If I go with a regular screen protector(one of those cheap $1 ones will that still cause issues?
Yup, the oversensitive proximity sensor issue started after 5.1 arrived. I too had a tempered glass covering the proximity sensor and it was working fine when I was on 5.0/5.0.2. I had to remove the tempered glass and get a new one which doesn't cover proximity sensor to fix this problem.
Did the same thing. Got a regular screen protector right now for a cheap, until I can find a tempered model that doesn't cover the proximity sensor.
I have installed Xposed and Sensor Disabler and have disabled the proximity sensor since I was guessing that it was that causing the error. But screen still goes black the second I call and stays black. Only way I can get it on is if called person hangs up or if I double tap the screen on button many times and then if I'm very lucky the screen turns on but easily turns black again very quickly.. What am I missing here?
old issue. Look for proximity sensor issue / failure. Happens with aftermarket screens, but also because of the ****ty sandwhich construction of the phone. There is about one mm friction possible for the frame, which leads to the slowly letting loose of the screen. Have a Z3 compact like that. tried glueing (B 7000 glue) but still. I can see the light inbetween frame and screen. Only a hardcover can possibly maybe prevent this screen from dis-attaching itsself from the frame. I rooted mine as to try disabling the proximity sensor, but I also failed doing that. I actually bought a Z1 compact again. Easy to fix. Thats why I thought the Z3 compact would be an upgrade. Well its not. Its build-quality is a nightmare. And repair also sucks. I even bought a screen plus frame new, and after installation I already saw space between the frame and the screen. Can't sell mine. Its useless. Stay away from this model. very, very bad.
Hi everyone!
The phone has bad ghost touch issue after a new screen was installed. And I am not able to pin point the cause.
Sometimes the issue is very bad with ghost touches more frequent with a ghost touches repeating under 1 second, sometimes the touches are much more rare. After the first installation I took the screen off and just reconnected without installing it and it had no ghost touch issues at the time but the issue returned when it was assembled.
Do you have any similar experience or idea what contact/connector/plug might cause the problem?
Thank you in advance!
I have tried to reinstall a full factory ROM but that did not help. The issue exists even on TWRP screen so I guess it must be a hardware problem.
Ghosting is a known issue with this phone. You can find many different solutions, but nearly all of them is about insulation.
The first method: Try to install some insulation under the main speaker. But be aware, if you put too much insulation there, you'll be unable to put back that plastic piece correctly.
The second method: Put some insulation onto the back of the screen like this.
The next two method are my own solutions to this problem, these fixed my ghost touch issues on my second Mi 9T Pro.
Fully assemble your phone, then place it on a completely flat surface with the screen pointing downwards. Now try and push each corner of the phone. It it remains stable, then move to the next idea. But if you feel that the phone is bent, then take a regular hair dryer, heat the phone with it's lowest mode everywhere for 5-10 minutes, then place something heavy on the back of the phone (like an older notebook or a desktop hard drive) until it cools down. Repeat the process if needed, but be careful, too much heat can cause other issues if you're not careful enough.
And the final solution: Remove the glass backplate, and the plastic cover with the main speaker. Then take a look at the bottom left corner of the phone, where you should see a hole in the frame, and some black insulation tape in this cutted hole. Remove that piece of tape, and gently push that orange-yellow circuit against the back of the screen. If it moves too much, you can try to wedge it with a piece of plastic.
I hope one of these solutions will help you to fix your screen. An extra tip for you: If any of these solutions work when the phone is fully assembled, don't try anything else, otherwise you'll risking to make the problem reappear.

I wouldn't recommend hairdryer as without being careful it's easy to damage parts.
Someone, maybe IFIXIT came up with nice suggestion to use hand warmer and heat it with microwave. It's almost ideal solution, as it's not overheating and applies heat everywhere.
Disable three finger screenshots and ghost touch issues will be gone on 5 point touch displays(replacement)
