The screen doesn't feel smooth when dragging items. I have tried cleaning the screen but hasn't helped. Looks like I will need to get a screen protector. I have a white unlocked hero
I get that too sometimes...i find that it wont be as evident if you dont press as hard.
Also think its due to being how sweaty your point of contact is...
Agreed on the sweaty thing.
the longer i use the screen, the stickier it gets. especially noticeable when i am playing air hockey!
wipe teh screen and my thumb off and all is well again.

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

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!
So I removed the included screen protector since it had a deep scratch on it. I read on the forums that you don't need the protector and that it actually works better without it.
Well my experience has been the complete opposite. Ever since I removed the protector I'm ready to smash this bloody phone. It's next to impossible to use due to the humidity in my area or something. The SMALLEST amount of moisture on my finger tips or even in the air will cause the screen to go haywire and register touches all by itself. Apps will open by themselves...i can barely type anything as it keeps typing multiple characters on it's own or other silly stuff. If I wipe down the display it will work fine for the first little bit until it gets that tiny bit of moisture from my fingers on the screen again and it starts going haywire again. It's a hassle just to try and unlock the phone from the lock screen at times.
So is my phone defective or is just the suffering I must incur by living in a humid area. I can't use the phone like this so I guess I'll have to look at buying a new screen protector. But if this is not normal and is a fault in my hardware then i would like to return it and get a different phone. I didn't really have issues with the screen protector on.
Ive kept my screen protector on my phone, works fine until i have moisture or (rain drops) on the screen, then my phone doesnt respond and also misfunctions the position of where i touch on the screen not sure if this is normaly as its the rain drops on the screen..
Tested witht he iphone 4 in the rain and works brilliant, why doesnt the X10 do the same !! :/

As you may know, those screens are capacitive displays, that means they're activated by sending (very) small amounts of electricity and are kinda "looking for a conductive material" in order to register an input.
The conductive material can be your finger, or something like... a raindrop or your screen, so that's why it thinks you're pressing that part of the screen...
Now it's even more obvious without the screen protector since it's directly on the screen.
As for why the iphone doesn't have issues with that, it does, but the screen being multitouch it's not as bad...
thanks for the info.good to know.
I didn't like the thick screen protector as my thumb/finger seemed to drag and not slide smoothly. I took it off and replaced it with a slightly thinner protector. I'm much happier with the feel now.

@smok3yjk - probably best if you do as Angelahp - get another screen protector on there.
I know alot of people who have complained about hitting the home or back button while playing a game or something like that and I think I've found a solution. I have the amzer case and no screen protector but this may also work with a screen protector on. Basically what I did was take an old screen protector and cut a very small strip the width of the screen. Then I installed it right above the Samsung logo. Since then I haven't hit the back or home button once. Let me know if this helps anybody.
Great idea, I just did this too. You don't even see it but it stops my fingers from sliding down into that area.
Just got myself a transformer today and it seemed great, however right after about 5 minutes the thing goes nuts like someone is swiping or touching the screen. Mostly just one spot on the left side and it will do it whether I'm holding it or it's sitting by itself. Can't seem to find anything posted about this wondering if thats because it's not common or I'm just not looking for the right stuff? Any help would be great, will likely return it tomorrow anyhow but if there's a fix would be nice.
Yeah, I got this as well while playing Angry Birds (F'd up my scores ! ). I don't know if it will work for you, but I just cleaned the screen really well with a cotton ball and alcohol, dried it, then used a microfiber cloth to clean it up (the ones that come with glasses, screen protectors). It worked for me, i think there was some gunk on the screen and was registering as a touch..
Try a factory reset and if it doesn't work take it back for a new one.
Thanks I can't see it being something on screen but will give it a wipe done here in a minute. Also tried the factory reset seemed to help but still getting in same frequency just not as badly. will see if the cleaning doesn't work I'll take it back and replace it.
This is the biggest annoyance that I have as of recent.
I have particularly oily fingerprints which causes smudges constantly.
I love the sensitivity of the TF, but if there is excessive smudging, the residue will register as a screen input - Wish the sensitivity could be adjusted.
Weird things happen when I need to clean the screen... I.E. I will be using a browser and use a single touch to scroll down, but it will zoom in/out instead; the long press menu will show up in a random spot persistently; -or- the screen will be completely unresponsive.
When this happens - I turn of the screen, clean it, turn the screen back on, and I'm good to go (note: sometimes I cannot even see any smudges where I am having issues).
This happens to me FREQUENTLY when i use the tab outside during humid days. I am thinking a screen protector may help, but still havent gotten one to try it out.
I had this same problem before the touch screen completely stopped responding on me.
For mine it only happened after waking it up from sleep mode though. When I turned Timeout to Never the ghost touching stopped.
Well tried as suggested the cleaning of the screen and all that but it still did it so took it back to the store got lucky and they still had one left, and exchanged it. New one hasn't had any issues at all. Thanks all.
I just took mine out of the box for fun (it was packed up for rma) and when i turned it on the touch screen worked. The ghost touching stopped to. But i still have a strip from top to bottom on the right side of the screen that registers two touches . So ill probably still send it in for a replacement.
