Typing often misses letters out because the screen is not so sensitive. The top layer of the screen seems saggy too and makes a 'sticking' sound from between the 2 layers when tapping with the stylus.
I may send it back.
Anyone else with this issue?

There has been an issue reported where an oil spot appears between the 2 layers and the fix was to pull apart with duct tape.
Doesn't sound good either way.

After owning the Touch HD for a full month I just noticed that down the middle of the screen there is something which I can best describe as an oil stain. It looks as if there is a liquid in between the glass/plastic screen and the resistive layer that lays on top of it.
The screen works normally and this "stain" can only be observed if I look at how the light reflects of it.
Any idea what happened?
Hi,
I have a small idear. The TFT-Monitor ist touching your Touchscreen. Probeply you pressed something on your HD, that the two Monitor touch each other, that is why it looks like a Water or Oil spot.
This can happen for example, if you are carrying your HD in your trouser pocket.
If you want to try to remove this spot, you have to turn with your both hand the hd, like the right hand turn with the clock and the left hand turn to the other way.
Sorry, my english is not very good for such a discribing. What I mean is like "to contort" or "to skew (up)". But you have to be very carefully. Before you start, remove the Battery
(I'll be incorporating a clearer explanation along the lines of what Dude10 was trying to say)
The effect you're seeing is IDENTICAL to what causes the colours to appear on an oil film actually!
The way the Touch HD screen works is to have the hard glass (polycarbonate plastic actually as far as I'm aware, but that's not important here!) with a squashy resistive sensor layer on the top.
This resistive layer detects touch as an increase in resistance at the spot that's compressed - be that by a finger or a stylus. Because the upper layer can be compressed, it can also be malformed by stronger than normal pressure, such as an object in a pocket. The effect can be more pronounced if your body heat warms up the screen surface making the screen "set" in position rather than spring back as it should do...
The "oil" effect is cause by the reflections of light from the outermost plastic layer and the outermost surface of the hard screen. When the gap is small enough, these reflections can interfere with each other, cancelling and re-inforcing different wavelengths depending on the thickness - hence the tapering of the screen from thinnest to thickest results in a "rainbow"
Now, why explain all this you may ask? Partly because I like science and it fascinated me in school to learn what caused that effect so wanted to share this! (And this also explains why it only presents itself when you look at the light reflections)
Anyway, more importantly, the solution to your problem is to restore the thickness of that part of the touch layer to it's original uncompressed state.
I'd firstly start trying to hold your finger flat against the top of the phone screen (on flat surface, portraint orientation, finger "left to right") then pressing resonably hard (the hard screen should protect the device - if not you're pressing too hard!) slide your finger down the screen from top to bottom trying to keep an even pressure. This should hopefully even out the surface.
Failing this, as Dude10 suggests, take the battery out and use your thumbs (holding with fingers in the battery well) to press and "smear" around the problem area.
Unfortunately, other than this I don't think there's a particular way to remove the effect totally if it doesn't work...
Obviously it's speculation given that you didn't mention how it happened in the first place, but it does sound like it got knocked or pressed by something either in bag or pocket - maybe even a fold in the pouch
Hope you manage to smooth it out!

Just a long shot, but:
Sometimes a similar effect can be caused when some moisture has got between the layers of a display.
Have you used the phone anywhere damp or very humid ?
Keeping it somewhere warm and dry might be worth a try?

Thanks for all the tips. The issue happened when I had the Touch HD in the pouch and in my pocket - so the idea that it was a fold in the pouch holds water.
The funny thing however is that before I saw all of your replies I was already out the door (with the Touch HD back in the pouch and pocket). 5 minutes later when I pulled it out the issue was gone. I am guessing that I reapplied the exact amount of pressure needed or something like that.
Thanks again for the tips and especially to chaosdefinesorder for the nice explanation.
Thx for helping explanation
5 minutes later when I pulled it out the issue was gone.

no, i don't think it was gone. check again under a fluorescent light....
i have this on my diamond. my HD is flawless (till now...)
i phoned to a technician and explain the phenomena and he invited me to replace the screen. when i got there, to my complete amazement and embarrassment the stain was gone. only later i discovered that the stain is visible under fluorescent light only.

thanks m8, already tried this (on my diamond) and tried now again with both yr methods. no results. the stain is still there...i think only a replacement can solve it.
here u have the paralel thread in diamond forum:

you can not do it yourself. the best way will be to go to your seller or straight to HTC, because I think you HD still have warranty.
I repaired ones an Diamond and I can tell you, it wasn´t an easy way.
This is my first phone with a capacitive screen, so perhaps it is a quirk of them, but I have noticed that if I am not holding the phone in such a way that I am touching the metal bezel, the screen does not recognise touches that are close to the edges of the screen. It seems that the screen requires a circuit to be made with other metal parts on the phone before recognising the touch.
For example, if I put the phone on my desk and touch the backspace key with a single finger, nothing happens. If I keep holding my finger on it, and touch the metal bezel, hey presto, the button clicks.
This reminds me of a watch a friend of mine had a long time ago, that had a capacitive "hair trigger" button that only worked for him (because it required a circuit to be made with the back face of the watch, meaning when he pressed the button it completed a circuit through his body)
Anyone else noticed this? It is slightly annoying because I have to hold the bezel when I want to use the phone..
Confirmed.
And you might very well be correct in the assumption about the circuit not closing in every part of the screen. I think it's the nature of any capacitive surface tbh. If you press in the middle of the screen then there is enough adjecent space to actually complete the circuit while on the edges there is simply not enough space around your fingertip to not close the circuit at all. That is why touching the bezel works.
But as I have been holding my little Hero in my hand while typing anything I simply didn't know this little odd thing. I have read about it though.
Yet another reason to hold your precious little Hero in your hand...
Wierd not like that on my samsung.. its all plastic tho
Mine is the same.. especially on the right hand side of the screen. If it's in a case it makes it really bad!!
Sounds like bad shileding and grounding to me
Didn't notice this until I put a screen protector on but now it's really bugging me.
On a related note (metal bezel related), I've noticed that in dim lighting the button backlight flickers. But if i touch the screen and bezel, it stops.

Same here. Could it be that the screen protector slightly touches the aluminium casing and thus grounding the screen (or creating a wrong potential)?
I noticed that when i touch (=ground) the outer aluminum frame with just one single finger then the touch screen works flawlessly.
(I'm using the offical HTC screen protector).

Hmm definatly bad grounding issue. Its either some pretty poor design or a defect.
i confrim, using hero without touch the metal edge result in less responsivity and difficult on multitouch operation
hope new firmware can solve this, too many errors using it like a normal keyboard on a table!
i have applied the de-sensitive cab but when i use my finger to press down and drag selections, i can never be precise .. the screen starts to "shiver" around like Jack from the Titanic ...
hmmm is there any tweak to reduce this?
BTW, do i need to align the screen regularly?
thanks!!!
appreciate any help on this
I too have the same problem. I have read the other exhaustive thread on screen problems but couldn't come to a conclusion. Is this a software issue or hardware fault?
Do you mean the built in tactile feedback vibration where the screen buzzes to let you know it's been touched?
Settings/Personalise/Vibration/and then uncheck the box
Try the screen sensitivity reducing tips, or better still use BSBtweaks, it has a toggle to reduce sensitivity that works.
also, i found being too gentle with my fingertip makes it juddery. a firm press with the pad of teh finger works better for me than the tip.
I align my screen after any hard reset / rom flash.
i had this issue too, it appeared suddenly a few days after i upgraded the radio on my previous rom. with the current combination everything is in place now.
I would say it is a hardware fault. My first HD2 was perfect with no screen sensitivity issues. Unfortunately, it was accidentally damagaed and I had to replace it. The replacement unit did suffer from the sensitivity issue and although the sensitivity fix improved things substancially, it it still wasn't anywhere near as good as my original unit. So it went back to the store and they game me a replacement which I am happy to say doesn't have the sensitivity issue and is a joy to use again.
The new unit does however have an uneven backlight but I'll probably live with that as it's the lesser of two evils!
omg why cant they built it right one time!
Are you guys using a screen protector?
I used to have perfect screen behaviour. Recently, I saw the multitude of cheap 3 for $x screen protectors, and tested about 8 different brands.
Some were pure crap, didn't prevent fingerprints or oil...
The mirror ones and some clear ones killed sensitivity!!! Made my touches jump all over, my presses inaccurate.
Some matt screen protectors were too thin and were absolutely useless (and easy to scratch).
Only a few were good enough not to cause a problem.
Can only suggest you try remove the screen protector if you encounter the same issue.
Cheers
Unfortunately this is a known problem:

Getting the device changed has helped to reduce this in some cases.

i was trying out the iphone, i noticed
iphone screen is matte.. no stickiness if sweat and swipe is smooth..
hd2 glossy if you sweat, you get friction... swipe depends on friction
if i were to put a matte screen protector, maybe it helps? anyone knows about this?
IPhone 3gs and HTC Hero both have an oleophobic coated screen which greatly reduces fingerprints and smudges. HD2 does not. Don't know why HTC don't use this tech on all of their capacitve screens.
ok i used a matte screen protector... result = smoother flicks and less finger prints.. but shivers is MORE...
hmmm what is wrong with our screen? * i tried iphone... NO ERRORS in typing..
could it be our software compensation for errors is screwed? u know as in the software is predicting the center of the finger wrongly

all people i know has this issue i think it is software htc is not a fool company to release all devices defected
and i wonder why they take so long to fix it..
Can any others confirm if this occurs on your device. With the keyboard out if I press the bottom right corner to the keyboard portion I hear a distinct sound like its loose or something..
Mine creaks when I push that area, I'm not to worried about it any slider phone I've had has done something like that when the keyboard is out.
Yes that's exactly the sound I was referring too. Creaks... Any others confirm? As long as others are experiencing this I won't worry too much...
like rsacipher said, just about every slider I've seen creaks a little bit. if that's all it is i wouldn't worry about it. however if the sliding screen feels loose or if there's a gap between it and the main body then i'd definitely have it replaced.
I love my Defy+ as much as anybody here. And a whole lot of thanks to Quarx for his efforts to keep our phones up to date.
I have got one nagging issue. The left side of my touchscreen (roughly 8mm from the left margin from top to bottom) is not registering any touch at all. The issue has been there for a long time and I am not able to find a cause or solution.
I am having difficulty while keying in Q/q/1/Z/z, some times a/A also.
Thank you.

Unfortunately, this is a hardware problem. There are (transparent) conductive strips crossing up/down and left/right the display that senses the touches, one of the strips is damaged. Had this on the upper part of the display, right under notification bar, and couldn't access some buttons on apps. You'll have to change the glass cover on the display. Search for "defy digitizer", "defy glass cover", "defy touch screen" or so. A new one (not original but works, although it's not gorilla glass, so it's easily breakable) can cost as little as 10 $

I would rather bear with this issue than putting on a cheap digitizer.
