My capacitive touchscreen has been having a pretty odd issue. If I lay the phone on a bed or desk and try to use the touchscreen with only one finger, I get all sorts of weird input on the screen. Then, if I touch the phone casing while repeating the same motion with the same finger (anywhere on the side of the casing or rear panel) the touchscreen works flawlessly.
Right now, my device is sitting on my bed, if I unlock it and try to pull down the notification window shade with just one finger, it's impossible. If I touch the casing with another finger and then try to pull down the shade, it's flawless.
From my understanding, in a capacitive touchscreen, a layer of electrons (ions?) is passed over the screen and a sensor detects where the flow of electrons is interrupted by the electrical conductivity of the human body. It seems that my phone is having issues with the electrons not just flowing over the screen, but around the casing as well, causing issues.
Anyone else experiencing this?

This appears to be a significant issues of owners of the HTC Incredible. You might get more useful information in that board, seeing as how they've been experiencing it for much longer than we have.
Wow, the video that they have on the Incredible forums of the phone on the Styrofoam is exactly the same issue I am seeing on my device.
I would link it, but apparently new users aren't allowed links. Ugh, this is a real bummer. Especially since that guy had 2 replacements sent to him, both with the same issues.
I too am experiencing this. I want you to try something a little different. Pull the kickstand out and stand it up on the bed. Then put your finger on the kickstand and you should be able to pull the notification bar down all the way to the bottom and let it lock with your other hand while still keeping the finger on the kickstand. Then take that finger off of the kickstand then slowly bring the notification menu bar back towards the top with your finger. Tell me your results. And i'll let you know if we had the same.
It appears that HTC has got some serious quality control to enforce on their recent devices. At this point, releasing a flagship phone with these issues is nothing short of unacceptable. I'm as big of an HTC fanboy as they come, but I'm really considering switching loyalties to Motorola is this crap continues. It's bad enough being capped at 30fps on the Evo.
If I put my finger on the kickstand I can pull down the notification bar completely, without issue. When I let go and pull the bar up, it works, but looks like it is trailing behind where my finger is by about a half inch, until I get roughly 3/4 of the way up to the top then it passes my finger like i'm not touching the screen anymore.

That might be the touch input lag we're experiencing as well. This may be tied to the 30fps graphic limit on the Evo.
The 30 fps limit is disconcerting, but that seems like it is something that could be fixed through firmware, however I doubt this issue is fixable.
Yeah, that's the exact same response I received from it; except when going back up, i reached the 1/2 way point on the screen and the notification bar shot up.

Well this is slightly depressing.
Ugh, my curiosity got the best of me, and the results aren't pretty.
When I lie my Evo down on a flat surface, the notification bar becomes absolutely impossible to pull down unless another finger touches any part of the phone. A test on the multitouch visualizer app shows that the screen completely stops recognizing my finger when y1 is equal to 40. This is essentially the entire height of the notification bar.
This isn't a deal breaker in any way, but what the ****, HTC? Is this how you treat your customers?
On mine, my screen becomes effected as early as y=500, then gets really bad around y=250, then is completely unresponsive after y=100.

wow, that blows, mine does the bad response -40 thing. holy ****, it's really just one thing after another with these phones...
I guess there is no such thing as a perfect phone no matter how much money, research, and time is invested into it.
I too have this issue, I have noticed occasionally its hard to pull out the notification bar, but when I pick up the phone and pull bar with other hand it works perfect.
For the heck of it I tested my Evo on every surface i could my hands on from glass, to thick carpet, bed sheets, etc, etc. Mine doesn't seem to have this issue, so it's definitely not every phone. If it's a big issue for you, you may want to see about getting it replaced.

Thanks for the thoroughness of your test!
http://www.youtube.com/watch?v=_kJ_fR02suQ i recorded it so people can see what's going on.
Have any of you contacted Sprint about this? I'd definitely try to get it replaced ASAP if I were you, hopefully the next one won't have this problem.
I spoke with a lady from HTC today and she said that they were aware of the grounding issue before it was released (during training). She didn't say whether it could be fixed or not though.
mine works perfectly fine i just tested it right now

At first I thought it was either a fluke, or just not happening, but now I know it definitely is. I can press onscreen keys and buttons without actually touching the screen.
I've seen recently that there is a screen tech that registers hovering fingers but I'm not sure if the ClearPad 2000 hardware can do this. "I'm not sure" meaning "I have no idea."
Interestingly it is affecting the way I type as as I type and skim over onscreen keys, I will sometimes get that "run you finger across a piano" effect. If that's makes sense to people.
I do know that I have a habbit of giving an electric shock to many things and people. Maybe I'm just highly charged and it's affecting the screen???
Is it just me that gets this?
i just had a few try's and i couldn't do it, i had to actually make contact for anything to happen
AFAIK, capacitive touchscreens work by reacting to the natural hand capacitance (i.e. the tiny amounts of electricity stored in your body). Therefore, I suppose it makes sense that different people can have different levels of capacitance.
No doubt someone who knows will be along soon!
Sometimes, the screen can be very sensitive ... and sometimes, you can accidently touch the trackpad.
Yeah, I experienced this issue as well.

As already mentioned, capacitive screens do not actually register your finger touching the screen, but just the electric field your fingers produce when near to the sensor. The sensor in this case is actually a grid of thin wires spanned across the screen, you can see them when the screen is off and hold the phone at a certain angle to a lightsource.
So, depending on the calibration of the sensor, a finger will get registered even if you just hover over the glass.
No chance to hover and register a touch on mine, albeit when I hold the phone with my normal left-hand grip - my thumb being just above the volume key - it registers as a touch on the screen so a single finger slide doesn't result in a scroll but a zoom in/out. I really can't stand the length of the volume key.

perhaps its the optical track ball ???? That will do it ... 1cm away from the track area the screen moves. as it should
Nah, for me it's not an issue with accidentally rubbing the optical trackball. Plus I've tested this a number of times. I can hover a finger over the screen and get the screen to respond. So when the keyboard is up, I can type without touching the screen. Seems to work best with my thumbs. And interestingly, my right thumb works "better" (if I can call it that) than my left.
Maybe I am just highly charged. Especially when the weather gets hotter I give a lot more things electrical shocks. I'd better hurry up and get a protective case!
This has happened to me quite a lot. I wasn't entirely sure if just psychic? Hahaha!

Thanks. But I prefer to believe I have supreme ethereal powers.
ok soo i dropped my Tilt 2 from a standing point (which is about 5 and a half feet since im 5'9) with the phones keyboard open and screens tilted, whats funny is that no battery fell out or anything, it just shuts off, i had to turn it back on.
when i shaked the phone i heard a slight rattle and i reckon its from the Flex Cable from the LCD screen, the rattle stops when i have my Tilt 2s keyboard open, but when i tilt the screen i can hear it slightly...is that normal?
also what is going to aggravate me for the rest of the time im going to own this phone is that when im using the phone's software keyboard on portrait at say like a 15 degree angle i can hear taps which is quite annoying but if i hold it at a 45 degree angle it stops, i turned the phone to the side i notice a gap, not a big one and not really noticeable but id say its roughly .5mm thick, i push the screen down and the gap gets smaller, is normal as well?
plz let me know thnx a lot
short answer.... no.... not normal. You knocked something loose inside hence the rattle, WHICH you probably already knew The gap, also not normal. Well wait.. I should correct myself. This is all probably totally normal for people who have dropped their phone. You're lucky you didn't crack your screen or do more damage and the phone's still usable!

hmm, well i talked to one Tilt 2 owner and he said he has that rattle and he hasnt dropped it? but like i mentioned, the rattle must be coming from that Flex cable that goes between the motherboard and the LCD screen....
No rattle and no gap on mine, but I've only had it 5 days. Give me time.
I have rattle too, but i think its the G-Sensor !

heres a video of the screen problem im having
but its not as worse as his but you guys get the point
I just dropped my phone yesterday with keyboard out and tilted and I got a similar problem to this. My screen only has a gap when I pull it up, which I wasn't able to do before, but the screen slide is now about 1 or 2 cm's to the left causing it not to line up with the keyboard slide. Somewhat aggravating, but totally unnoticable unless your holding the phone. I don't get any rattle though...

hmm
well if i were to dismantle the phone and repair the little bridge that goes across the back of the LCD screen would that solve the issue? because it seems when i push on it it seems to fill a gap but idk if thats what causing the whole screen and kb issue but im going to do it when i have the chance
I have a tilt and mines exacly like the one in the video with the vary small gap and the screen wobble, I always assumed it was normal, mine dosent rattle though
that little gap and the screen wobble.
it just because is got movable parts, look at the screen hinges if i can call them that.
its the reason i didnt want to get mine, ive always chose candy bar phones so i dont worry about that.
but i did get me a tilt 2 and have dropped it too, i also think my wobbly screen started after i dropped it, but ive had it a year, since it first came out. the only thing i hate reall bad about this phone it the lack of a headphone jack I HATE THAT WITH A PASSION.
Well,i noticed some odd behavior the other day with my phone laying on my desk at work. It was completely unresponsive. So I was just fooling around, laying the phone on my bed, same thing. I realized that unless my other hand is touching the phone, the screen is unresponsive. Think this is some sort of grounding issue? It isn't a big deal, but I have never had this problem on other phones. Anyone else have this problem? Try sitting it flat on a desk without touching the body of the phone and see if the touch screen functions.

Dont quote me on this but i read on how touch screens work and it basicly like you said the screen has a charge and when you touch it it slightly changes the charge and thats how the cpu monitors the change and tells the screen to act the way it does. But i am not sure why the screen gets less responsive when your not holding it in your hand. It happens with my G2 and my G1 so nothing new but maybe some one can actually explain what is going on.
Fear the static
The answer is quite simple; it's cooler outside so there is less humidity in the air. With lower humidity you have a higher static charge on your body (hence why you can zap someone more easily in the winter than the summer). Since the screen is capacitive (relies on small changes in the charge on the top surface to know where you are touching it) and you have a larger charge on your body, the digitizer sees it more like you bringing three or four fingers in close proximity to one spot. The reason putting both hands on it works is because you now give the digitizer a reference charge to distinguish and ignore.
TL;DR - Winter static makes screen think you are ham-fisting it.
Solution - use hand lotion to help dissipate your body's static charge from your fingertips, just don't use so much that you end up leaving greasy streaks on your screen. If you do, wipe the excess off of your hands with paper towels until you don't have lint tracks in your hand, TP is good for this.

Now i will begin to tell my gf how the Screen isnt HEAT sensitive and why during the winter time with cold hands it responds differently.
i did notice this behavior the other day, and to be perfectly honest it scared the tar out of me, but then as soon as i picked the phone up it was fine again. i guess you really do learn something new every day, i always thought the capacitive screen reacted to heat, but i guess not.

Does all capasitive screens react like this are some phones just more prone to it?
Last night while using the phone I noticed this slight clicking sound from the bottom right corner of the screen (touch-sensitive panel). So I kept pressing it and I wasn't hallucinating, its there. Also figured the sound also comes when I press the bottom right or bottom center edge of the phone. The creaking sound isn't loud but its noticeable when I hold the phone in specific angles and while typing if haptic feedback is on, I think the vibration also makes it happen(weird)
So except for this my HOX is fine and am wondering if I should get it changed.
Are there any long term effects to this? I'm starting to just ignore the sound and trying not to make it happen purposely
Depends, does it make the sound when you're using it normally? If it does I would consider swapping it, although you said everything else was fine.
If on the other hand, it makes the sound if you hold it in a certain way and push unusually hard then I would say stop intentionally pushing it in a weird way and use it properly.
People have been complaining about "screen flex" along the side of the phone when they push on the edge and run their fingers along the side. Want to get rid of the screen flex when you push the edge of your phone and move your finger along it? STOP PUSHING THE EDGE OF YOUR PHONE!!!
Just remember that some phones have had screen flickering, yellow marks and even scratches under the screen, you may not be as lucky as your were the first time if you choose to swap it.
what you described is not flex even, most mobile devices have a creak some where
Flex should mean the screen is literally loose to warrant an exchange

my first flexed bad (soft one pressure, loose) on the left side, although i loved it so much because it had the much more dense yellowish sharp screen
second hox had a bad coating and slight flex on the left side, also hot pixels
third HOX my current is perfect, the screen is rigid on all sides expecially left and right, but it creaks if its around 50degree hot on two out of the four corners, very very slight creaks and only happens if it test it intentionally, it has the acer white screen with visible pixel grid, so the first hox screen i miss so much
im saying don't replace for a little reason bro it will be a bumpy ride, if the screen is loose then ok, you can see it by testing for light bleed in a dark room or if its physically moving
I think my screen is perfect. I can't figure how you're suggesting I test it, but pressing along the edges with slight pressure doesn't cause any change in the screen. The pixels are all good and no flickering. I think its a yellowish screen and not the bluish one.
How do you find out what LCD brand is on your HOX?

Hmm I don't think I'll get it changed, I love it too much . Just have to get used to the occasional/random creak/click sounds from the device.
Im posting in regaurds to that phenom known as "zombie finger". I appearantly have the zombie finger affliction, and curious as to why. Old school resistive screens dont have this issue.
A little background, growing up electronics have been known to act strangely for me. Infrequently, computers which normally work fine for others had a tendency to just fail when i would try to just power them on. Only thing that would fix this 100% of the time was standing up and allowing someone else to sit down and boot up.
In one town, there was a series of street lamps which would turn off when i walked close and turned back on after i passed by. Albeit this didnt always happen, however my friends could never get it to happen.
Appearantly, I am somewhat sensitive to e.m. fields, best description of the sensation would be pressure. I start feeling more pressure around my face, giving me a slight headache and causes me to either cross my eyes abit, or makes me want to just close my eyes.
Watches and such tend to drain quicker than normal, i give them about a month.
Sticky hand syndrome as well, meaning, i can place my hand on light enough objects (paper, plastic cards, small stationary items) lift my hand up and whoa magically levitate the object with me. Flat handed palm down with verticle lift. Touchscreens suffer from this effect due to my finger not wanting to slide across the screen (when its actually registering my touch).
Could these experiences be linked to each other in some fashion? I do know my body chemistry is different than most (A.D.H.D. is fun) , and blood type (AB-, yes im one of the 1% of the population). This issue has been just a minor annoyance to me, however intriguing. Anyone have any insight into this?
Sorry about the long winded nature of this post.
