Hi,
I think I may have made a mistake, but was wondering if anyone else has / has not had a similar experience.
I got my Touch HD a couple of weeks ago, and although I was completely knocked out with its amazingness ( new word, patented by me! ), something bothered me about the amount of pressure I was having to use, particularly in the centre of the screen when touching.
I know there have been tweaks and hacks posted and the pressure required on the touchscreen is variable, so I fiddled and tweaked and carried on. It was only after I started using FingerKeyboard2 (which also warrants "amazingness" status.) that I noticed that when holding keys down and releasing for special characters and numbers, my HD was registering a second press upon release. So when holding for number "5" I got a letter "t" too when I released. This really annoyed me.
I've had a look from a varry shallow angle at the screen, with the device turned off and pressed in the middle and compared to the edges, and it seems as though the digitizer "domes" over the screen. There's a large void in the middle that's not present at the edges, which means that to register touches in the middle, I have to press the digitizer against the screen. I think this is causing the double presses, and having to apply extra pressure in the middle.
Anyway, to cut a long story short, I've taken it to CPW today and they've sent off for a replacement, which will arrive on Monday
Has anyone else noticed this, is it normal and I've sent a perfectly good Touch HD away? Have a look for me please, and spare an old(ish) man his sanity!
I can only speak for myself but, specially after tweaking, the hd screen is VERY sensible to touch, no need for hard presses at all. I think you actually had a faulty machine...
My touch screen is very good, shame the wifi has died on it and it's doing strange things. Mine will be back to CPW as well
My touchscreen works very well, without tweaking I think it does the job and recognizes my presses easily and accurately. However, my problem is that I can see the touch sensors even when the screen is turned on... I see small green-coloured dots, in a regular grid, specially when I have a white background. Annoying, but I think I can live with it... Better than send it to the service and wait a long time, with the risk of getting a new screen which may have dead pixels (I don't have any now).
Thanks for your replies everyone, makes me feel better about not having my Touch HD over the weekend. I pick up my replacement tomorrow and I think I'm suffering from withdrawal already.

Anyone else notice that the edges of the screen on the cmda diamond, cdma pro, and the HD seem to be MUCH less responsive than the screens of previous devices?
I "miss" the exit and start menu buttons pretty often and its pretty annoying lol.
Also the notification/title bar area plus other buttons along the bottom and side.
The rest of the screen is more responsive certainly than say the vogue, mogul, diamond or tp. But its the edges of this and the last 2 mentioned devices that get me..
Well I also feel it's less responsive, but not so much actually. Besides this is caused by the technology of the touch screen.

You mean the edges or the whole thing? The main part I feel is more responsive...
Edge responisiveness depends highly on screen calibration. Try to recalibrate screen more precisely, I think situation should improve ...

Hey thanks a lot. Thought the same thing myself.
Re-calibrated as accurately as I possibly could.
Still no go. I would really like someone else to try this. Take out your stylus even and press in the very corner of the X-button...you get nothing.
Sort of fix: I found that if you hold your press just a little longer it registers (much better) though I'm not quite convinced that it's still normal nor complete.

I don't see any problem in pressing X-button on my Touch HD. I had similar problem like yours using right vertical scrollbar and recalibration helped, so I though it might help you too, but unfortunately it seem this ain't the same problem

Hmm...I wonder if I should try to get it replaced under warranty.
I would want to, but I have noticed the same problem in a sprint diamond in the store, a sprint touch pro in a store, and a friends sprint touch pro.
What do you (guys) think? Replacement? It could get really annoying...not being able to close out of things. Right now since its new and awesome and stuff I'm kind of trying to ignore it or whatever but...hmm idk.
The fact that the screen is less responsive near the edges is caused by an inherent technical limitation of resistive screens. The screen has no real bezel, and thus, the screen is attached to the body frame right where it ends: at the absolute edges of the screen Where it is attached, it cannot move. A little further away from the edge it can move (eg be pressed down) but this requires more force since you need to bend the screen much closer to the fixed edges than when you would press the center of the screen, which bends the easiest.
Don't know if this makes sense, but it's like a window... Hitting it in the centre will break it much easier than when hitting it close to the edges, since the glass bends much further/easier at the center, so the same force will have more effect.
Anyway, resistive screens have this problems, capacitive screens do not, obviously, since they do not rely on pressure.
If hitting the OK/Close button is a problem for you, just use the hardware button below the screen, the one with the arrow on it. It does exactly the same thing I believe. With 'I believe' I mean I assigned OK/close to that button using AEButtonPlus, which should be the default behavior for pressing it once. I find this to be much more convenient than trying to hit that tiny X/OK button.

Hey thanks for your informative opinion.
This theory seems to fit, except it doesn't quite explain nor fit with these 2 things:
1. I can apply a pretty decent amount of pressure in the corner with no results whatsoever. But I can get full results if I apply less pressure for about .5-1 second rather than just tapping.
2. I have never seen any evidence of this on any other resistive touch devices (vogue, titan).
Why in the world do these resistive touch screens have to suck so bad anyway? The HD is the best I've seen lately, but does HTC just suck at it, or is it everyone (haven't owned a non-htc ts device for a yr or so, and that was a treo where I didn't really notice sensitivity).
My dad has a 3+ yr old Dell Axim X5 and that screen is AMAZINGLY sensitive. Responds to stylus and is too old to be capacitive. But it is literally 100% as responsive / sensitive as the screen of the iPhone. When I used it I couldn't believe it. You had to be VERY delicate and careful and trying hard to touch that screen and not have it know.
Hello!
I had my Touch Dual for about 1 year... now it's time to say goodbye
It started with a small stain on the touchscreen... It was about 1mm in diameter when i recognized it. Back then the touchscreen was still working. This stain was since then growing and one day the touch screen didn't work anymore... it behaves like if I had my finger always pressed on the screen in that area. The rest of the area is still responsive, but it is impossible to control where it detects the tap.
Also it is extremely slow. When a call comes in, it takes about 20 seconds from the screen switching on till I can start to talk... so I'm missing most calls.
Just try using the phone while never releasing a specific point on the screen
The stain is still growing... Its now 9.6mm. I think the liquid inside is leaking at the border of the screen.
See the picture I attached!
Now I got myself the Touch HD which is a really great device! (I made that picture with the Touch HD 5Mpx camera)
I only hope this one will not start leaking after 1 year!
best regards!

Hi, I'm a big fan of the HD2 but in the last two weeks, since i own this device, i'm getting confused by some screen imput behavour that i will present you.
I want to figure out if this "screenbugs" i have to fight with every day, are normal or a hardwaredefect. To make you guys an imagine of what i mean, i uploaded some youtube videos for each bug.
1. The first one i call: The painting edge
This bug is only present if i not have installed the less sensitive CAB from this forum.
Explaination:
Many of you have notice that the glass of the screen doesn't fit exactly in the case of the device. The right bottom of the glass protrude a very little. Then i lightly press on this position, the screen notice a press on the right top...as you can see in notes on my youtube video:
Video 1: http://www.youtube.com/watch?v=c49x9vB4bzQ
------------------------------------------------------------------------
Beforce you say...my device doesn't having any of the following bugs, REMEMBER, This bugs are not present every second. Sometimes i can use the device for 30min without having some of this.
------------------------------------------------------------------------
2. The Electrocardiography
This bug, i think could be the reason for the following bugs.
Explaination: Trying to draw a straight line an you think you device will get a heart attack soon.
On the half of my second try you can see how the device suddenly works normal again.
Video: http://www.youtube.com/watch?v=t54m1dSLnV8
3. The shaking Screen
Explaination:
I have notice that some other guys have this bug too. You can see this on every scrollable screen, like opera, IE, zoomed pictures, the manila tab, startmenu...etc. etc.
Best seen on minute 0:54 in my video.
Video: http://www.youtube.com/watch?v=6hIE_wV4djs
4.The non pressed key
Explaination:
You are cofused about keyboard reaction while writing a text message? You type an "a" and getting a "t"? Than you have "the non pressed key" bug how i call it.
you have to watch on some key input where my finger is totally out of range. I don't mean the fault input next to the key i pressed...
Video: http://www.youtube.com/watch?v=_B1GiyMp_O4
----------------------------------------------------------------
There is a fifth bug i didn't get on video yet because it is very rarely.
I had have this bug only 5-6 times since i own this device, but it sucks realy hard.
I call it
5. The self-typing keyboard
Explaination:
Then i'm typing some text sometimes the keyboard begins to typing without having the finger one the touchscreen. it can be have a duration of 5-10 seconds or 20 letters/numbers.
It can also be watched, without keyboardaction. Then the screen scrolls wild in any direction without any finger on screen.
Video: http://www.youtube.com/watch?v=-fdXU8SoPTg from htcracer211
----------------------------------------------------------------
If someone can tell me if i can embed the youtube videos in this forum...
Go get a replacement, the screen is perfect. Although I admit it does not fit correctly but it is great. I only need the earpiece fix
please watch the videos before you comment anything...
...You're too much electrostatically charged...
...Or something of electrostatic is in the range of your device...
But it's like your touch panel is faulty. Get a replacement (warranty rules)
Have brought it back today...but couldn't get a replacement...no devices
tryed all your test and get no errors on screen, electro worked perfecly, keyboard keeps presing same key without leaving the range, and i cant notice any shaking effect.
So probably your screen is faulty , change your device as fast as you can matte
I have brought it already back, but it seems to be that others have all my listed bugs too. take a look at the poll results. On another forum a guy has tested the "painting edge" on 3 devices after he saw my video and all devices have this bug!!!!
Hey Guys,
I have the first 3 bugs on my HD2, too. But with BSB Tweaks 1.31 i solved the first 2 one by activating the option "Screen Sensitivity".
Hi,
If you look in the sticky thread here somewhere in the LEO section about tweaks and registry changes there is a topic on reducing the sensitivity of the screen.
I think what's happening here is the electric current in your fingers is playing havoc with the screen when your fingers are either close to or on the screen.
Let us know if this helps you.
WB
whow, that's a lot of problems for one device.
I have the "non pressed key issue" : (that's annoying as hell, typing a message is a heavy burden now) and the shakey screen. should i bring my handset back or try the tweaks... I didn't expect this from an 600€ handset

When i was made this video my finger was always with the same pressure on the touchscreen. It was not close...and not weak on screen...normal pressure. And you can see at the middle of my second try where i'm drawing lines in notes that the screen suddenly works normal.
I also wrote in my first thread, that this bug is not every second present...but then it's present its also the reason for some other input errors, like the "non pressed key" i think.
Quick question: How much pressure do you apply to the display (what is "normal"?)? Scince your display is reacting weird to pressure on the bottom right corner, any pressure might be linked to erroreous behavior. Do the shaking related errors remain when you don't press at allk?
to the OP: what ROM are you on ? have you tried 1.48 ?
I can recommende you to use screenprotector film and install cab for less sensitive.
But even without this all I had not this problem Looks like your sreen very sensitive for electrocharging and not have normal ground contact. This is way to warranty service.
lmao >.< sorry mate but get a replacement NOW!! I've never got these problems, everything works smooth and properly, sorry about that...
do u have a screen protector? i am wondering if the screen protector does anything bad to it...
You have the exact same problems I had when I first got my device, the main concern was the device having its own mind and making random key presses, even without you touching it or even being near it. I got my unit replaced and the new one works like a charm.
I noticed today that MY PERFECT SCREEN starting acting weird !!!! Its jittering !!! Damnnnn !!!!
I'm totally spooked by your video's!!!
I personally never experienced these bugs so I spend the last half our replicating your bugs.
The only thing I noticed was that Electrocardiography but I think you have your finger too flat on the screen (it has a too large surface area) because when I write on the screen as if my finger where a pencil (straight up instead of flat) the screen is working as it should!
I think you must have a faulty device. Perhaps try to flash it with 1.48 if you haven't done that already.

On iPhone with exactly the same finger it draws almost a precise straight line. This problem comes directly from HD2's screen, not from fingers, weather, humidity and so on.
I'm wondering if anyone else has seen this. It is clearly a hardware issue, and I doubt there's much I can do since it's not under warranty AND has a hacked bootloader, but:
If it gets jostled too much, especially if a particular spot near the dock connector gets much pressure, the screen "glitches" and it becomes unresponsive. It even happened yesterday when it was on my lap at a 90 degree angle and fell over onto my stomach. It's very difficult to use it for more than a short 5-10 minute period without this happening unless I'm SUPER gentle with it.
The screen comes back visually and can continue to be "glitched" with that slight pressure to the right spots, but it never comes back to responsiveness. I have to hard reset.
I can create a video of this behavior if anyone thinks that'll help.
The whole thing is unresponsive - even with a mouse or keyboard attached, no response, so it's not like just the touch sensitivity is gone. I doubt anyone does, but if there are any ideas / good places that will repair it for a realistic fee, I'd love to hear it. Thanks!

Why not just pop off the back cover and take a look around for loose connectors? Won't hurt anything.

i have no such problem here matey and i ride a bike with the a500 in a laptop bag all day.
I've had my Nexus 4 for a couple years I believe now, and overall it's been a nice device. I've had occasional issues now and then with software (Camera not available message, random powerdowns) but no hardware issues. A couple weeks ago, part of my display stopped responding. The LCD itself shows everything, there's no bars, no visible cracks in the screen. but the left hand side of the screen, I'd estimate about 1/5 the screen in width, no longer responded to touch. The far far left edge, along the very edge of the display, registered, and on the other side of that 1/5 worked fine. The area that was giving me issues was right about where the 'a' key on the keyboard is in portrait mode -- the only location I could press to get an 'a' registered an 's' as well.
This is all being tested with the developers Show Screen Touches and Show Pointer Information turned on.
Then, the end of this past week, it got worse. The entire left half of the display still shows fine, but almost never responds to touches -- maybe 1 in 100 times it will. Thankfully, I was able to get in one of those times and disable my screen lock. It seems to be able to register as far left as an x value ~418. This means the back button in portrait mode, for example, no longer works. To make me even more confused, it seems to register phantom presses. The device can be lying, powered on on my desk, no touching it, and the display starts showing screen touches -- the most common one I see is right about where the word Google is in portrait on the stock main screen. These will continue indefinitely.
All this to say, I suspect my digitizer has had a mechanical failure. Does that seem a reasonable conclusion to you? I like the four inch form factor of the device, and with most new smartphones getting larger and larger, I'm shying away from changing to another device. I've looked briefly at replacing the digitizer -- it seems you can purchase either the digitizer alone or with the LCD, and that when replacing just the digitizer it's easy to accidentally create problems with the existing LCD. Is that true?
Also, the part about having to use a hair dryer to pull the components apart makes me a little nervous. Screws and cables I can handle, but a hair dryer?

I would say it's most likely a hardware problem with the digitizer. The lcd/digitizer assembly is glued together so it's very difficult to separate the two without damaging the lcd.
Unless you have the tools to separate them properly, it's alot less headache to get the entire assembly already glued together.
