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

So I've been having some weird problem with the touch screen wherw there is input from something that gets stck down in the lower left corner. Using CM10's developer options i can sometimes see how closw to the edge of the screen it is. WHen this happens, i'm unable to input, or the input has an abnormal effect (well, normal if you were to keep your finger on the screen). Turning off the screen returns input to normal (at least temporarily).
It comes and goes... i spend a lot pf time woth mu phone in my poxket riding my bike. I have a Nillikin soft rubber case.
I think the squeeky corner is connected, as it seems I can sometimes get it to go away by fiddling witj the squeeky corner (pushing in various directions).
Does anyone else have an issue like this?
Does anyome thing the issue could possibly be related to having a somewhat old screen protector, or the case, rather than the phone's actual body/case?

Maybe I'm just retarded, but I can't seem to find the setting to recalibrate my screen.
It's been slightly annoying me because I bought one of those fancy adonit styluses, (The ones witht he plastic disc, supposed to be more precise), and it works great, however when I turn on the "show touches" function, the touch from the stylus ALWAYS registers slightly towards the edge of the screen.
If I touch in the center of my screen the touch registers dead on, but the closer I get to the edge screen, the further off it gets.
I've noticed something similar on my tablet. But in my case, the best alignment when showing touches is in the upper left corner of the screen. As I move farther down, the touches start to come up slightly down and right of where the stylus is touching the screen.
So It's been a couple of weeks and Ive still yet to find a way to fix this slightly annoying accuracy issue. Does anyone know a way of doing so?

Try flashing ts-20 from sfnub's thread, works better for me
My screen seems to be showing a bit of warping right at the bottom of the screen near the back and home buttons, right on the edge of the screen. Not so much that you notice but it warps the light if you use the screen to reflect the world, and only in that spot. Bit disappointed considering its a totally flat piece of glass!
Anyone else got this issue? Might get onto three about it. I'll see if it's widespread first.
I'll try get a picture later, or video if I can.
Warped like raised wavy or warped like wrapped screen that goes downwards into it at the edge? If either of those makes sense..
I saw that when in 120hz mode, but it looked more like an intended effect to me. It wasn't unpleasant in my eyes.
Also seemed to only happen on long scrolling windows. Short scrolling I could not see it.
I would say it's a pinch under the glass, but the glass looks fine, just reflections of the surroundings in the glass so right where the back button is. It's definitely not lifting and looks flat, but the light dances and create an almost m shape. It's far from anything serious, as you need to look for it, but just something to keep an eye on for early adopters.
I don't think the screen refresh affects it, as I can recreate with screen off.
Got pics from the screen, using my **** ipad camera. But you can see the warp. The white shelf is flat, being a shelf, so you can see it shows as straight up the screen then at the bottom forms an m shape.

Huh, i can see what your on about.
Mine doesnt have that, so maybe your device has a defect.
So i bought the a50 cause i wanted a bigger phone like the note at a cheap price. Loving the phone, so i decided to spring for an active stylus, the stylus actually works very well on my g6 and dell touchscreen but for some reason the upper half of my a50 isnt very responsive, and where it does respond is only on the edges. If i start a stroke from the bottom of the scren it will follow through to the top, most of the time. But if i start at the top and move down, it only appear towards the bottom off the screen. Tapping is even worse, almost no response on upper half.
I have no magnetic cases, ive tried two a50s, with and without screen protectors. Always the same result. Heres some pictures to help visualize, does anyone have a fix for this?
Scribles represent dragging, dots represent taps.
You could try increasing the touch sensitivity.

Thank you for your response. I should have mentioned, the problem is identicle, with or without touch sensitivity increased. The stylus work on a note 9 perfect as well. Starting to suspect its a software problem with the a50.
