Suspected touch screen problem - Touch Diamond, MDA Compact IV General

Hi,
I've had my Diamond for a bit more than 2 months now.
Recently I had an odd problem with it.
The touch screen seems to be busted.
The display works fine. However, it doesn't respond to any of my touch commands and it seems like someone is touching the screen randomly, as in, random clicks on the screen.
The hardware buttons work fine, it's just the touch interface of the screen.
First I assumed it was a ROM related problem, as this happened just after I installed Shine On. So I went back to the original ROM again, but the problem persisted. Then I tried another ROM, but same problem!
Therefore I suspect the hardware.
Am I right to assume that the screen is built up of several layers? Such as the TFT screen it self, the touch part, protective glass part, etc.?
This was a week ago and I've been using my old HTC since (waiting for a reply from HTC customer service which haven’t replied yet! ). However, three days ago I tried the Diamond again, and it seems to work flawless..!
So, I'm wondering if anyone else has seen this intermediate problem? Or if anyone has suggestions what could cause this problem?
Thanks for reading

Same s*it!
Hey mate.
I am experiencing the same problem as you do. The touchscreen does not respond or not accurate enough oder in a completelly different ponint than is poninted at. Readjusting screen helps for a while, soft-reset helps for a while. Sometimes it goes away without doing anything special. Did HTC finally answer your E-Mail?
I'd like to have this fixed as soon as possible.
Edit: I noticed that this problem disappears at once if TF3D is deactivated. Let'S see about that....

Hi,
even though there are probably several other threads concerning this issue, this seems to be the most recent one.
Do you use a (genuine?) screen protector?
I do.
I suppose this problem is caused by the tremendous heat* when the device is used and a screen protector that had been applied wrongly.
I might have applied the screen protector wrongly so there are a few very small (almost invisible?) bubbles (i.e. hot air expands(?) - I don't know the technical term),
since I had to remove the screen protector once because of dust..(does the glue lose its stickiness?)
I don't know if it's because of the bubbles, but I'm quite sure it's because of the screen protector.
Has anyone noticed this behavior without using a screen protector?
(I'm going to buy new screen protectors if neccessary, but I don't want to pay ~25€ if it's not)
*= I've adjusted my screen when my device was "cold".
Edit: I've probably found the reason for this issue: there's a deformation (caused by HTC) on the bottom of the screen(at the end of the screen protector) - there's a hole without glue (but air) - everything works fine while closing the hole by pressing the screen protector on the surface of the device.
I'm going to upload a picture later.
Edit2: The picture is now online. The fact that there's a hole isn't new of course, but no one seems to have linked these two issues so far.
(Correct me if I'm wrong)
The hole wasn't that big first but it grew because of all the testing
I've cut the lower part of the screen protector off now until I have a new one, although it doesn't look that great anymore..
Edit3: Ok, it's the hole and not the screen protector - I guess I have to get a new Diamond from my provider since it's a manufacturing defect..

Touch Screen not working - Digitizer issue?

Have got a strange issue with my diamond
touch screen is not working, it seems to be tottaly out of alignment
have tried calibrating again, but the calibration tool just loops around and around, and doesnt complete
i had this issue the other day but was fixed after calibrating the screen
any ideas what it the fix is, or should i send to htc to repai under warranty
i have tried searching for an answer, but cant find anyone who has had similar issue
Digitizer issue?
maybe have a look at this
http://forum.xda-developers.com/showthread.php?t=412159&highlight=digitizer
Hi,
I am in the UK and found my touch screen started responding on the other side of the device, then it wouldn't respond at all.
It was pretty much all over the place until I called them up.
They sent a courier, collected the phone on the Thursday, returned it Wednesday so 5 day turnaround collecting and returning to my home.
I would strongly suggest going through them
re
i heawe same problems with touch,bath only fix in service ,it takes 2 weaks 2 repeair ....g.b.
A refresher - I had the same problem, but it turned out to be very simple to fix - dust around the screen.....
It is possible that between the screen and the cover there will sneak some dust and other particles. They will exert the pressure over the screen, fooling the touch-sensor. You need something thin and preferably firm (like bit of plastic screen) and go around the screen - GENTLY - there's electronics inside!
I did it, and all returned to normal... And I was scared that I will be forced through the whole "servicing" proces....
Anyway - worked for me!

Touch Screen & Reset Button Problems after Wetness

Hi folks,
I have accidentally made the horrible mistake of letting my HTC TyTn II sit in a small puddle of water over night. That'll teach me for keeping my phone and glasss of water right next to each other on my nightstand.
Anyhow... It actually still works, which suprised me. However, 2 elements are not working. Specifically:
Touch Screen is not working. The LCD DOES display the image just fine, it just does not respond any longer to TOUCH.
The reset button seems to be completely non-functional.
After I got over the initial "oh &$*!" moment, I did some searching here and about for answers. I found some references to just replacing the digitizer, which I can get quite cheap on ebay. However, I also read that it might be a mainboard problem, in which case I might as well just replace it.
So, thoughts?
Also, here is the eBay auctions I was looking into. They seem reasonable? (if I decide to go that route)

Thank you much for the couple moments of your time.

Diamond touch screen not reacting when touched.

The touch screen of my htc touch diamond is not working properly. It does not react to my touch. For me to get it to work I have to rub my fingers over it then it will be work again as normal. This only lasts for a few minutes after a while it becomes non responsive again. It is like it has to be warmed up to get it to work. This a problem when it comes to sending text messages. (the problem remains when I remove the protective screen).
Anyone has a answer to this?
remember the last program you installed and remove it , maybe it cause this problem
or try hardreset
Tried both methods still not working. I have ran out of ideas. Anyone else expierenced this problem?
Im having the same problem with my Raphael
To really know whether it is a hardware problem or software based problem, I recommend a hard reset and see whether the problem persists...
this is likely to be water damage on the screen. send it off for warranty see if they fix it. they fixed it for mine.
The thing is iv noticed the touch screen isn't thermal reactive like most touch screens. In other words the temprature of your finger is sensed on thermal screens, the HTC you can use anything solid that makes contact. Usefull if you have long nails.
So I'm guessing its probably hardware if it works after a while of 'rubbing' it, But like otacon said I would do a hard reset before jumping to that conclusion.
Same problem
Hi there....i saw that this is an old thread but did you manage to get it to work?
Cause i have a HTC Diamond that i changed both the displays on(LCD and the "point screen") and everything works fine on mine now,even tried to recieve phonecalls and it works excellent so as i said EVERYTHING works like a charm but the touch function.....it doesn´t react in any way while trying to use the touch function and i have tried soft reset,hard reset,new rom,checked all the internal connections around 4-5times and everything is ok but the damn touch function won´t work whatever i do with it.
I haven´t "glued" the 2 screens together,but they are sitting close to eachother so it should work anyways right?
Now from what i have seen on internet is that there are different versions of touch screens available on the market and i ordered the LCD from one company and the touch screen from another.
Could it be so that they aren´t compatible together or am i doing something wrong?
I´m still stuck at "Tap the screen to set up your Windows Mobile-based device" and can´t get any further after trying another rom.
Please help me out if it´s possible.
I have exactly the same issue you're experiencing, I've actual flashed the original rom, thinking that might put every settings in place to make it work, but no joy.
I don't be leave the concept of the weather condition equate to the performance of the device, as read in some of the forums. reason being I've had mine in very hot climate Country for over year whiles working on a project in Africa. In fact that was when I realised the the screen has become unresponsive.
I think this is a hardware issue.
It´s working perfect again
So since my last reply i ordered a new touch digitizer and lcd display and soldered them together carefully(first time i bought a lcd and digitizer from two different companies so they weren´t compatible with eachother and made the touch defective and second time i bought both digitizer and LCD screen from the same company and then it worked) and it has been working perfect since i last wrote my comment so i recomend you check the contacts/connections first on the phone because i had some minor issues with them when i assambled the phone again so i had to #wiggle# the contacts so i made sure they were connected.
We had a company here that sold lcd displays and digitizers out for a total of 30dollars with shipping so i had nothing to loose on it so that´s why i ordered a new set again and that made everything work as a charm since i replaced it.
Now i have searched online about the displays and the digitizers and i have found out that there are atlast three different versions of them so if you order a digitizer and a LCD make sure you atleast order both from the same company so it doesn´t happen the same to you what happened to me the first time.
Cheers and hope i helped you somewhat or else just ask on and i should try to answer.

Think your Digitizer is broken?

Think again, before you purchase a new one or think you are capable of replacing it, when you're actually not.
Last week I was replacing a screen protector because the previous was getting dust underneath the corners. After replacing the screen protector I was not receiving any response from the touchscreen because I probably pressed down too hard on the screen. I proceeded with several soft resets and finally caved in to do a hard reset (which I hate performing because it is a pain reinstalling data, resynchronizing, and installing apps). After the hard reset touch screen was still unresponsive, which sucked because I arrived at the alignment screen.
So here is what I did. I opened the tilt screen and proceeded to push with little strength from the back side (where your sim card is placed) with my thumbs in a forward position, while gently massaging the screen with my remaining eight fingers. I then used those eight fingers, while proceeding to push outward with my thumbs, and pushed inward. Sure enough my screen was responsive again.
So before you decide to purchase a new digitizer try my technique because you have nothing to lose.
thanks for the cheap, but helpful technique
hope all is well hadn't seen you around for a while.
Interesting... does this make the device more fragile.. i.e. a slight drop or nudge and no response again?
Glad your device is working again!
It sure does look like a nice thalassotherapy for the phone anyway .
I don't understand why people are capable of replacing a digitizer. I replaced one.

I am more than capable of replacing one. At the time, I did not have a device I wanted to use as a backup because they were for sale. All I had available was a rinky dink Moto with hardly any contacts saved to my sim.
Over the past year I have read numerous stories on this forum and others while people applying their screen protector and suddenly their touchscreen was no longer working. Then as they were spending money and time replacing their digitizer, only to find out it wasn't as easy as they thought.
I was upset that my device wasn't working and figured, "hell I'll push it in the opposite position", which I did. The touchscreen works just as well as before.
I'm having the same problem (not responsive to screen taps), but I'm not quite getting the procedure you described. Are you trying to push the screen harder from the back side - and how much pressure are you using?

[Q] Touch screen dead spots

This may be a problem beyond the scope of android, but seeing as I'm running it, I thought I'd try here first.
I've noticed that the lower left hand side of my screen has a "dead spot" where touch is simply not registered. To illustrate, I went to screen calibration's test screen and drew a straight line along the edge of the screen. (See Attachment)
I've tried recalibrating the screen (manually and resetting to default calibration) as well as wiping data and reinstalling the system. Reinstalling the system worked once, but then the problem came back and subsequent reinstalls did not fix the issue.
I'm running Incubus26jc super froyo [RLS 12] on the 15-07-10 340X480 Froyo Kernel.
Anyone else seen anything like this? As far as I can tell, the problem is not getting any worse. Currently, it's only a hindrance when trying to use keys in that region, but I can work around it by switching to and from landscape. It's a bit of a hassle, so I'm hoping someone may be able to shed some light on the situation.
I was sure it was hardware until the system reinstall fixed it, but am now baffled as I can no longer replicate the fix.
I have not tried reinstalling the kernel but will at some point in the next day or so. I'd like to avoid switching back to WM to check if the problem persists, but may have to... we'll see. Doing everything I can to make this phone last until the Incredible month of February when I'm up for an upgrade.
dont know the issue resolution... but i have the same with my touch vogue.. and in the same 'area' apparently as well.
hard for me to hit the 'a' key on my keyboard. hehe
I'm glad to see I'm not the only one... anyone else?
Bottom right corner for me... I was able to calibrate around it but it took a few tries.

The sensitivity across my screen was inconsistent some time ago. I found that years of my abuse had taken a tole on the exterior of my phone. It eventually got worse and I bought a new housing (with a new digitizer) on ebay for a reasonable price. If it is hardware then it really isn't that hard to fix if you like taking things apart.
If you're sure that win mo accepts input from that part of the screen then nevermind my post. I would play with a painting app though and investigate the hardware further.
I may be talking a little out my a$$ with this part but.. is it possible that in calibrating your screen the os may change it's settings on how hard you have to press and such also. that may be how you got it working.
In any case, my investment in a hew housing was well worth it considering how modern my old phone has become thanks to the developers here.

In my case, no - when drawing a straight line down or across the screen, the line starts 'moving' away from the stylus (like the picture in the OP).
Gah... now it's shutting itself off randomly and the dead spot has grown. Not good at all.
Yeah, mine was better for a while then 'slid' again. I ended up swapping the digitizer with my other Vogue and things are back to normal.
Sent from my Full Android on Vogue using XDA App
I have another vogue, but am weary of doing anything like that. How hard was it to get done?
All you need to do is switch the front half of the housing rather than the digitizer itself- it's not hard. There's a teardown guide somewhere in the forum, Google Vogue teardown and it should be at the top.
Sent from my Full Android on Vogue using XDA App
The only thing that worries me is that my spare vogue exists because it was dropped in a muddy puddle. I'm hoping the water damage isn't too bad. Guess we'll just have to see.
it is really annoying
I have the exact same problem and I too thought it was a hardware issue till I saw this Thread. I was ignoring it till two days ago when it started really bugging me. Now, I don't even need to press any button and it automatically gets pressed around the curve and I have a google search box there, so it keeps on searching for eee or sss randomly and started draining my battery. Is there a proper fix for this?
I thought I'd chime in too... I could never seem to calibrate the touchscreen properly in either Android or Debian. Changing the screen resolution (i.e. msmfb scaling) seems to have no effect, whether it's 240x320 or 640x480. Any area within 5mm or so of the edges of the LCD will register as the edge, making "A" and several other keys on the virtual keyboard impossible to hit. Passing calibration values to the kernel didn't seem to fix anything, but it's possible I was using them the wrong way...
i have the same kind of problem on my Kaiser... i think its realted to hardware... either the housing or the digitizer...
I am experiencing the same problem on X10 mini pro. the same screen spot exactly, i have to try very hard to get z or x or shift to work. Sometimes when I try locking the screen and unlocking it back, it works.
update
so after a very long time with this problem i decided to change the digitizer and problem is gonne. visualy the broken digitizer had nothing wrong with it. The fix was fairly easy though, there is no glued parts involved into getting a new digitizer on the u20i.
Touch Screen
I just bought a brand new Cubot One and it looks more than perfect! It has just a little problem with the touch screen ( I think its the software, need ROM change). There is a dead line on the right side of the screen that touch doesn't work at all. Any solutions? Anyone faced that before? Can I fix it myself or do I have to send it back for replacement? Is there any video or guide that shows its done?
I uploaded a video on YouTube to show the problem but i cant post it yet.. (new member)
You can write "Cubot One touch screen problem" and it's the 1st one.
Thank You!
