Edges of screen unresponsive?

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.

Oil-like stain reflection on screen

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.

I have it now,but not happy at all

1.first i had problem to hard reset it,it is not done as users manual says.
2.Digital Compass app needs to Rereset after each soft reset.getting "Magnetic interference" Error
3.Screen is so sensitive that is almost impossible for me to write text messages or e mails.came off Touch Pro 2.there i had no problems.
4.my Volume UP button sudenly stoped working
i think,they rushed the release and made this device pain in the ass.maybe we need a NEW ROM!!!

mine hasn't had these problems, knock wood. And I am loving the speed!

With the screen being so sensitive... why does that make it impossible to write text messages? it just means you dont have to bend your screen when pressing so hard to press a key...?

Having had a Touch HD - owning a TP2 (work) and just having sold an Iphone 3GS - I honestly love mine to bits.
Been playing with the phone all evening - and I have to say I am really impressed - Vibrant screen, awesome speed, gorgeous flash (vid's and pics are quite good too compared to my other/previous phones) - All in all I am well impressed. The OS sits together so well - not having to touch WinMo at all, that this is one ROM I might just stick with!!!
I like the hard buttons on the front of the device - one of the bad sides of the blackstone but I have to agree the screen is VERY sensitive. As I'll be getting an invisishield for it as soon as they are released - this will make it much more useable - struggling at the moment but I can honestly say its a good thing - VERY precise screen - compared to the iphone 3GS (which sometimes required a double press to register) - You just have to think about touching this phone and it reacts - lol
Overall - VERY PLEASED and super happy I ditched my iphone 3GS for this oh and its VERY slim - in fact one of the slimmest HTC devices I have ever laid my hands on. All in all about 2mm bigger in depth, width and height than a 3GS but with like 50% more display area - Now THIS is what I call an iphone killer.

heh, if your passing by hudds soon i.e. on teh weekend let me know fella and i'll hook up.

I agree on the sensitivity....it's awful....if, for example, you type something incorrectly...VERY easy to do..then press delete quickly a few times, it doesn't delete..it starts typing random characters!!
hoping there's a setting for this somewhere. A screen protector might be the answer though in the short term
I also had to hard reset (because I wanted to..not for any other reason) and I followed the procedure in the manual, has been the same for all HTC devices I've had

Not to *****, but the guys saying that the screen is too responsive... Are you used to capacitive screens? You need to get used to it for a bit, especially when you come from resistive screens.
Also, a phone that is TOO responsive? You never hear that from a WM phone .

compared to the iphone (yes, I know..I'm sorry) the screen is lousy!!

that's exactly what i ment.it is realy hard to wrife witbkut making a mistake.
So does it means that none of you guys hav this Digital Compass problem?after each soft reset i have to repeat that 8 shape pattern movement to make it work again.
anyway i am returning my to get a replacement.

I don't have an HD2, but I think I've experienced this over-sensitivity on my iPod nano, which I presume has a capacitive scroll wheel.
Sometimes (although not usually) it becomes so sensitive that I don't have to actually touch the scroll wheel for the songs to scroll. It then becomes almost impossible to choose the song I actually want because when I move my finger to the select button the song changes before I can select it - very, very annoying and frustrating. I'm not sure why it's sometimes much worse than at other times. Maybe it's the temperature of my finger or something.
Anyway, it sounds like this is the same sort of thing that's happening on the HD2. It's a real pain on my iPod, and I would find it totally unacceptable on a device like the HD2.

Its just a case of getting used to the screen. Our fingers are too used to resistive screens that we don't actually lift our fingers enough and drag across the screen since unless we apply enough pressure on resistive screen it won't do anything. With capacitive we just need to re-train our fingers to lift off the screen another 1mm and it'll be fine.
Here's my suggestions:
1) Try typing slower to start with.
2) Or turn phone to landscape as the keys on the onscreen keyboard are slightly wider.
I can type quite quickly in landscape with between 1-3 errors per an SMS.
I'm loving this phone right now!

I also was very frustrated and irritated the first two days. But then I realized how responsive the screen is. Just a very very light touch already gives a reaction. And now I'm loving it more and more by the minute...

Just try another keyboard. One that doesn't allow to change a character once you pressed a character on the keyboard. Fingertouch Pro and Resco Keyboard Pro for example are great keyboards for the sensitive screen of the HD2. I myself like the Resco keyboard. It responds and looks very similar to the iphone keyboard.
BTW Fingertouch pro and Resco Keyboard Pro both allows you to make use of gestures. Together with this feature text input is a breeze on the HD2
(Better yet is MessagEase, but unfortunately, under WinMob 6.5, it has some real problems).

Hey I am in wakefield too! Small world
I have to agree the screen is very sensitive. I am sure with a weeks usage I will be ok.
I have to say though I am so in love with the phone. The speed is perfect. No more waiting to load SMS\email screen etc like with my touch HD.

Hehe thats what happens with everyone who switch over from Resistive to Capacitive, at first they will hate it as they're too used to resistive.
But just within 2-3 days they realize just how much better Capative is. Resistive just sucks IMO. Typing is way quicker using a Capactive panel.

I had exactly the same experience switching to my G1 - I sent the first one back after a few hours as i was convinced the screen wasn't working. The next handset was was the same. A day or so of use later and I was sold and never looked back.

no..the screen is definitely too sensitive...this is not my first capacitive screen btw.
I've got my phone on charge on the desk next to me...and number of time it has open the calendar, or contacts...all by itself is amazing. A few moments ago (which has prompted me to write this post), it opened the calendar and the curser moved all over november....18, 19, 20, 24, etc etc...without me being anywhere near it!!
there has to be a way to turn the sensitivity down

Magnet attached at the back cover

Hi all! Im in love with this community from day 1
its my 1st thread though seeking for help/advice/your superior knowledge
Thing is that i want to mount my phone in my car using a small magnet attached somewhere at the dashboard and stick my HD2s back cover which is metallic...
my question is: is it possible because of the nature of the magnet to cause problems in the phones operation?? like radio interference or something like this?
looking forward to your answers

i think a magnet may interfere with the touch screen. not positive on this but am sure i`v read somewhere about tiny magnets being in the tip of some capacitive screen stylus`s. a stronger magnet to hold a hd2 would surely result in some type of touch screen interference. but like i said am not a 100% certain.

magnetism will not affect a capacitive touch screen. It will however mess about with the compass!

A capacitive Touchscreen works like a capacitor, whichs field is "spread" over the surface of the screen. By tapping you will change the the resistance of the oscilating resonant circuit, which has a specific resistance (which is related to the dielectric medium, which is changed by your finger)
With this, the phone is able to locate your finger in X + Y axis to find out where you have tapped.

Yes, obviously it will but thats the least of my worries as it wont be permanently attached to the magnet and the times it will, i wont be needing the compass app.

Does this mean that a magnet at the back could interfere with the circuit of the screen? and if yes i guess is temporary right?

Is that true? I know old compasses relied on a magnetised needle to work, but I thought the compass in the HD2 got it's direction from the GPS and the accelerator software??? How would a magnet affect these?

no it's a dedicated compass hardware
Actually, even my notebook apparently hurts it! Looses calibration

yes several times when i opened the compass application arround various interferences it asked me to move it in the usual 8-like movement to calibrate itself..

what about the rest of the phone and memory and SD card wouldnt it affect the storage ? i clecned out my speakerphone with a very small magnet yesterday to get all the lil pieces stuck on it.
and after that my phone(touch pro2) completely froze up and kept freezing up after first input untill i did a hard reset.

i did another little test with a small round magnet around 2cm diameter. i moved it around the back of the phone while looking at the screen and i didnt notice any interference to the screen, at least to my eyes it looked like the magnet did not interfere with the phone at all.
However i moved the magnet to the screen and tried to touch the screen gently with the edge of the magnet and the screen responded immediately and it looked very precise too! i did several presses to the screen with the magnet and in all of them the screen responded exactly as it should, just like it should with the press of a finger, i even wrote some letters as text and it worked great. so i guess thats how they make capacitive stylus..
next time im gonna try to draw on notes application and see how precise it is on that.. (as long as i find a smaller magnet that i can handle better than this one)
i might try to make my own capacitive stylus....
why not....

I have attatched a magnet to the back of my HD2 so i can use my vent mount, i havent noticed any adverse effects.

why does the screen "shivers" when i place my finger on it...

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:

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
