Suspected touch screen problem

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 & 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.

screen problems?

i got my td2 just about a week. yesterday suddenly the touchscreen didnt work at all anymore! i was taking some pictures and then it stopped to do anything on the touchscreen. i rebootet the device few times but no go - even removed the battery but didnt work anymore. then i left the device a few minutes without battery and when i tried it again it worked. this scared me a little... because without touchscreen u are really lost with this phone.
ohwell.. i hope this doesnt happen again. but i actually got another strange thing here:
if i look into the screen from the side.. i can see a strange glimmer sometimes. it looks like oil in water... it does glimmer a little and its not visible all over the screen but the part does even grow. i noticed this yesterday and it was like 5cm long and 2cm width. but now its almost on the full screen and it looks like the effect when u press on a LCD screen really hard. but it appears without doing anything.. does anyone have that too on his TD2??

same problem here. its the device of a friend. one week old. but we didn´t managed it to bring it back to life again...
no we will try a hard reset.
battery was out for ar least 30min wizhout success.
even noticed some glimmer at the screen. hard to describe. like liquid between sreen and screen protector.... but only on those parts were we tapped on the screen...
no we try the hard reset - i´ll report how it worked.
somebody else with that problem here?

ok we tried a hard reset - no success. screen is dead. no way to setup the device. no reaction of the touch screen. will go to the o2 shop tomorrow and bring it back...

wow.. at least im not the only one. my screen is working again but the glimmer didnt go away. also today appeared one more defect on the screen - it looked like the protection plastic is moving, but then after some tapping on the screen it went away again. very strange!
the glimmer looks indeed like a liquid between the screen and the protection. sometimes its almost not visibe and sometimes its really good to see. i wonder whats going on here..

hey i just found something out!!
my screen has something like little bubbles under it when i do touch it on a certain area. when these bubbles are visible.. my screen does not work anymore!! then i can clean the screen a while with a tissue or my tshirt or whatever and the bubbles go away - as soon they are not visible anymore the touchscreen works again!!!
im tryin now to give that phone back and get a new one. i dont even have that phone 1 week!!

I have a Diamond2 with the same frozen screen issue. The screen just did not react to any tap. Soft reset may put it back to work again, but the symptom repeated after some time. Even hard reset cannot rectify the problem. It is hardware defect. Fortunately it is one week old and still within the one-to-one exchange policy and I can take back to the shop I bought push for an exchange. Having email HTC and they just ask for service check and refuse to exchange a new one. If you conduct a Google search of freeze screen, you may locate a lot of touch screen issue but only very limited solution. I suggest you to have the device exchange than going to repair.

Hi, I am experiencing the very same problem. Touchscreen stopped working. Taking out the battery for 5 minutes fixed it. But there is a oily liquid now beneath the screen. My device is 5 days old, this should not happen
Taking it to the shop on monday.

we tried everything but without any succes...
today we gave back the phone. it was within the one week limit. but there is another limitation: 15 minutes airtime! i said to the guy in that shop: when he can show me the airtime, we keep the phone - because than the screen seems to work again... )
but no problem they exchanged it against a new one! good service, very customer friendly at o2!

I encountered this one day after getting my unit. I got a replacement. It seems two layers of the touch screen is "stucked" together. Use scotch tape to lift up the area and and the touch screen responds. But the next time you press on the screen it will get stuck again.
So get it changed.

wow
what a great idea... never ever thought of that... *lol* but when you buy such a sophisticated mobile it looks very unsophisticated to lift your screen with scotch-tape everytime you tapped on the screen...

kinda yes. but not that big and after cleaning phone with a tissue it goes away. i will get a replacement in a few days.. hope this doesnt happen again - but shop told me it seems that there are a few ppl with that problem on td2!! :-(

ok i did get a replacement now and all is fine again. but i think i know what caused the problem.
actually i had the phone always in my back pocket of my jeans. this is not a very good idea when you sit down. the phone gets some pressure on the screen and my screen actually was lowered into the case a little bit. you can see this from the side. that did cause the air under the screen and also the oily liquid that sometimes appeared. so i think the screen felt into the phone case and this was causing the problems. my new phone does not look like the screen is lowered - its totally flat. so i will take more care and not using back pocket of my jeans again to put the phone in

I hope you are joking... I mean one can't be serious about carrying a touch screen device in a back pocket of his jeans. Are you even surprised about what happened to it? In fact I'm rather surprised you got a warranty replacement. There is a thing called User manual that comes with the device a it is saying 'Always remove the device from the pocket of your trousers prior to sitting down'. Yu are really lucky indeed you got a replacement....

well aint a mobile phone made for putting in the pocket? this is not my first phone and i never had such a problem even with a touchscreen phone. its not like i did sit on it with full force or something.. just had it in back pocket during cardriving. you can easy do that with any other phone without breaking it...

that's exactly what's it's not - it's a pda phone and it kind of makes sense to treat it differently from normal mobiles which can withstand all sorts of abuse. also if they ask you specifically not to do something because it can damage the device - and you do it and then you are surprised it happened. it's written there for a reason. they surely know that for many people it will be their first pda phone so they don't have much clue how to treat it...

[Q] Screen - Hard Reset or new digitizer

Help/advice needed please?
My incredible S starting playing up with screen touches, didnt worry about it as it was sporadic. However I then lost the touch at the menu button, this prompted me to installMultitouch Vis Test and noticed that there was a double touch registration on the line up from the menu button. I then installed Screen Touch Test and this confirms there is a line from Menu button straight up the screen, as well as another line close to the left edge not registering any touch at all. The advice I am after is 1) is this a software issue as there is no visible damage, therefore do I go for a hard reset or 2)Is this a digitiser issue and do I go for a new digitiser (£50 from guy in the local shops or £15 of ebay and do it myself)
I have not rooted the rom the phone is all stock and not dropped or damaged it recently.
Cant be bothered with the pain of hard reset if I dont have to, but if it saves a digitiser I have no problem with that then. Equally dont want to get a new screen only to discover it needs a hard reset.
Thanks in advance.

Maybe you should try to boot into safe mode. You can do it by holding up or down volume button (don't remember which, try googling it) on boot when HTC splash screen appears (release power button first). This mode will start your phone without loading any application you installed. This way you can see if the issue is made by an application.
If it still don't work I would highly recommend doing hard reset. It is not that much complicated to reinstall after a hard reset. You can use an app like titanium backup to backup and then restore all your apps. I'm sure many people here can tell you that a hard reset is nothing because we are used to do it every time we flash a Rom and I for example do it at least 1 time a month.

Fixed screen, aftermath was damaged digitizer, however after a few days the digitizer kicked back in and worked fine. After a few month the screen became unusable. Long story short, I didn't replace the digitizer and it only got worse so I recommend that you replace it. If you do, I highly recommend getting the special tool for separating the glass and lcd from the housing.

Oh well very valuable lesson learned!! I bought a cheap £15 digitizer and tools from ebay and took time out on a saturday to replace it. First off the little tool to seperate the screens broke on first use...managed fine following the youtube videos. Separating the two screens was a bit tricky but eventually managed it. Then replaced the screen and connected/built it all back together. Switched it on and watched as it was obvious I had damaged the LCD, either during separation or putting it back together. There was no obvious damage but it was goosed.
Decided to take it to the local guy at the shopping centre with the little booth to see how much to replace both. Was quoted £80-85 and told it would be end of the week.....ah nearly a week without my smartphone! Got a text message on Monday lunchtime telling me its fixed and that would £70, got there and he only charged me £65. Phone display is better, phone is more responsive and less sluggish that it was before too, and this was without a hard reset. Very happy as was dreading a hard reset.
Lesson learned, dont attempt to replace screens on own, leave it to the guys that change about 30-40 each day.
I presume the sluggishness of the phone was related to the screen problems also. Was contemplating a new phone, but can hold off now until Windows Phones 8 get their act together and one of the manufacturers decide to make a phone that fits my needs.
Thanks for advice guys.

An confusing issue regarding the infamous phone screen - Presses itself erratically

I want to give some context.
I have owned my Z1 since release on a contract. I have previously had the screen replaced twice and it worked fine afterwards.
However, I had dropped the phone resulting in the top of the screen cracking. Got it replaced by a local phone repair shop.
The result was a new phone screen, a white edge just over half way down the screen might be worth noting. The repair man said it was a warranty sticker on the screen they put in. (Sounds silly)
Anyway, the resultant problem is not exactly like what i've seen on many threads.
My phone now decides to press itself erratically. Usually after swiping and trying to press delete on the keyboard would it start acting up.
My remedy: Hard reset(Didn't work), factory reset(didn't work), upgrade from 4.4 to 5.1(I think, newest software) and to my surprise the issue remains. So after the repair man replacing the screen twice and ensuring that i'd done my best with little to no phone knowledge, I still have this problem.
There's many threads detailing problems, some linking to apk's that are "calibration software", some that say you can change calibration.ini but no helpful replies or expanding info on the threads.
Can anyone tell me if they've had any luck with this or anyone who has knowledge of what I should do next (E.g "there's no fix guy, you'll have to sell it and move on") as i'm starting to assume these screens are very tedious to deal with

Remove the plastic protector and put a tempered glass protector
