[Q] HTC Legend touch problem? - Legend General

Recently I found that the Legend sometimes behaves a little strange... sometimes I need to to push the display quite hard, not only to touch it slightly. And I found that this happens when the phone is left on a table and I am touching only the display( not the aluminium body). If the phone is held in hand or placed in the charger has no problems ... Here is a video:
(I still can`t post any links so please search youtube for exactly "HTC Legend touch problem" video posted from ggrozdanov5 to see it)
Is your Legend behave like mine do?

First of all stop pressing you display hard,that wont help anything. The legend touch interface works based on electrical current differences between your body and the screen.
It is most likely a grounding issue and is not an uncommon problem among touch screen phones. Try touching part of the metal body at the same time you touch the screen.

instead of pressing hard try to make just more contact to the screen
for ex. lay your hand palm on the screen (softly)
you screen is made from glass and will brake if you press to hard !

Guys, I appreciate the advices, but please don`t pay that much attention to the word "hard". If you had watched the video you would see what I`m talking about. I know exactly how to make my phone work correctly - just to hold it in hand, or touch it with a finger anywhere on the aluminium body. I wonder is this a problem for every HTC Legend, is it a problem just for a few devices, is this normal behaviour for an HTC Legend... and so on...

I don't get such behaviour

Not entirely true...As most devices have PCT (Projective Capacitive Touchscreen), this issue would not happen on them.
But I think the legend designers wanted to make legend cheaper, so they gave legend the SCT (Surface CT). Given that Legend body is anodized aluminum which held in palm has a low impedance, it is sufficient...but in cases like this it might not work so good...
I have this issue in bed when the phone is on the sheet or so, but most materials transtalte capacity changes pretty well, so it's not so annoying...

Is this Normal Screen Behaviour?

Hi,
Recently ive repaired a HTC Universal, put it back together as best as i could.
Now when i do touch the screen with a stylus, the screen has funny colours behind it. It kind of like when you touch/ prod your Computer LCD. It only happens when theres pressure on the screen so its not really a huge problem. The touch screen is definately there cause when i tap the screen it responds (e.g i tap start and the menu pops down).
If its normal then i can take it, but if its not im complaining to the ebay seller.
This doesent happen when i put any form of pressure on my HTC magician LCD, so im curious.
Let me know what happens with your universal
Cheers,
Whitemoo.
This is not normal behaviour of any touchscreen device!!
hmmm... well i just looked at the broken lcd screen, and even though the LCD itself is shattered, the touch screen is in perfect nick.
I put pressure on the touch screen and couldnt see any of the symptoms i saw on my current LCD
You guys recon i should swap the touch screen over? either way im complaining to the sellers, DODGY.
whitemoo.
from my knowledge, im pretty sure its normal. it happens sometimes on my 9000 so yeahh....

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:
http://forum.xda-developers.com/showthread.php?t=439410&highlight=oily+stain
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.

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:

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..

Recommendations for a stylus please

could anyone share any experiences for a good working stylus for the hd2?
this phone is stupendous but alas i have to use it for work and the software we use requires very tiny touches and signature signing.
have tried the ones on e-bay (rubber topped pencil turned upside down)
which is crap...have now tried the htc and dagi ones with the tiny red dot and they are just not cutting it.
has anyone done any homemade experiments or come across a moe "pointy" stylus
toodle pip amigos
I got some, and they were crap...

Unfortunately you are all too correct!
With the glass screen!
Put a protector on it and they work!
I have been using the dagi long slim one and it works ok, I do have a screen protector on though so maybe this helps... makes selecting text and writing Chinese characters much easier (I use my hd2 to study/translate Chinese so being able to use a stylus to do this is pretty great)... its a bit fiddly to start with as you need to learn how to use it properly, but once you get used to it everything is ok...
Most of the styli are crap, I need something with more of a point, but that's probably not possible. Still waiting for some sort of battery powered pen that offers pin point precision, a guy can dream right...
i'll try to put a screen protector on as suggested and try...
my problem is it's no good mastering the dagi myself as i have to get customers signatures and most people simply can't use it...
it deffo needs something more pointy.
i'm sure i read somewhere on the forum about a guy who was filing something to a point till it stopped working???
i'm so frustrated as this is the only phone in 8 years that uses my works software flawlessly...except stylii
I have ordered the official htc stylus 400.
arrives in 2 weeks and i'll post comments.
read a review after ordering that it actually scratches the screen!
I guess i should have waited for the 400/2 version!
look on the bright side, will probably misplace it by the second day anyway
I've tried using my DS stylus but that doesnt work, seems like it was made for bigger objects to come in contact with the screen (ie fingers).

It`s not about the size of objects. HD2 has capacitive screen.
"A capacitive touchscreen panel consists of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO).[2][3] As the human body is also a conductor, touching the surface of the screen results in a distortion of the body's electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location can be passed to a computer running a software application which will calculate how the user's touch relates to the computer software."
Wikipedia
thanx for input guys..i least i know about capacitive screens now thanx to kregowski...although i sorta knew.
so if someone could come up with a small pointy thing that gives off some sort of electro staticy stuff...we in..
the search continues
Got the dagi (10 euro from Hong Kong). I am not amused... Touching the screen with the complete tip flat on the screen is annoying to get used to. Often only the side of the tip touches the screen.
When the tip is flat on the screen (which it should) it just does not feel OK. Not "delicate".
Which the screen responsiveness lowered and the tap-reaction time increased (which I did just to be able to get some decent fingertyping results) the dagi does not function adequate. I have to aim more accurate then with my fingers and have to press the dagi on the screen.
Putting the screensettings to default (which I did not try yet) reinstates all the drawbacks in the other functionalities.

[Q] the 'TOUCH' has gone from my phone!

Hey, since last night my HTC Legend isn't able to be 'touched' I can use the menu buttons and track ball but it doesn't work with skin contact!
Has anyone had this problem before?
it never worked with skin contact
those are real buttons u have to push down

A failure of the touch sensitivity in an 8mm strip down the left-hand side of my 2nd Legend meant a replacement under warranty, it wasn't the whole screen though.
I downloaded some touchscreen test app which confirmed it.

the screen doesn't work, the push buttons do, eg. Menu, it brings up the boxes along the bottom but I can't press them on screen eg. Settings, LauncherPro settings, notification etc
it sounded like u were trying to "press" the menu button just by skin contact
sorry for the misunderstanding
It looks like your digitizer is read. I think this is what you need to buy:

I encountered the same problem after installing a Zagg screen protector. From reading around it seems maybe I pressed too hard with the squeegee when applying it. I got a replacement phone.
Every once in a while I experience the same thing with my new phone if I have it in my pocket for a while. Usually the touch comes back if I just set it aside and don't touch it for a while.
Seems like the legend screens are suseptible to damage from too much pressure on the screen.
I read a forum post on here somewhere from someone who claimed to fix the issue by using duct tape on the screen (applying it then peeling it back off to lift the screen a little).
