    Curious as to how many other people are having this problem.

    Basically, when on certain surfaces, or indeed even when holding the phone in certain ways, the EVO's top half of the screen will become insensitive to touch.

    Best way I've found to make this happen reliably is to sit it on some fabric/clothing, like a sock. The pants you're wearing will not work, it has to be something not on your person.

    More interestingly, is I found if I put my finger JUST on the kickstand, nothing else touching the phone, while it's on said sock, it will immediately work again.

    So, any of you have this issue?

    My first instinct says it may be a problem with the proximity sensor, have you tried a factory reset?

    Have you tried replicating what I described? I'm willing to bet this is not a one-off problem (although it'd be nice if it is so I can have it replaced).

    Not an issue with the proximity sensor, it has nothing to do with it. Doesn't matter how far away I am, issue will be the same.

    When my Evo's on my calendar (large paper type) or when I have it laying on a microfiber cloth the top quarter of the screen is unresponsive. It annoys me, but it's something I can live with.

    I have my phone laying down on the desk and am able to use the entire touch screen. On my lap as well and on the desk with the kick stand. I then tried it on a stack of papers on my desk and it works as well.

    I say the proximity sensor b/c something about it has the ability to turn touch off on your phone, maybe it's misfiring for some reason.

    Wow thats weird... I would of never known about this issue if you didnt point it out... I just put down my Micro fiber cloth and tried... its unresponsive for a few tries then becomes responsive... Its a Non Issue for me... I have no reason to have it on Fabric at all times... but interesting...

    Blanket, Sock, Cloth, could this be some type of static electricity thing?

    It does it on my desk in addition to other surfaces. I hope it was just a bad batch of screens. What would be the best way to report this to HTC/Sprint?

    Static free / Lint free cloth... Not an issue... but like i said before this is a non-Issue... For me at least

    I just tried it with the charger plugged in and the problem goes away. Annoying.

    Ah ha, good find. I bet that's why it seemed so intermittent.

    By the way, I took this into Sprint and demonstrated it, they sort of looked at me like I was crazy. Their answer was "Don't put it on those sort of staticy surfaces then". Sigh.

    Must be a grounding issue. Any ideas for a temp fix?

    Makes 100% sense.

    Question for you guys with the problem, what case, if any, do you have on the phone?

    Seidio innocase. I tried it with the case off and the problem was still there.

    I had no case, but did have Invisishield on it. No change after taking it off.

    How's the humidity where you guys are? Does it only happen in one place or like say at home and at work?

    I'm just trying to see if it's the environment or the phone.

    It sounds like something, either the phone or externally, is holding energy somewhere and is either tripping the proximity sensor and disabling the touch screen (only part of it, if that's even possible) or disabling the touch screen interdependently of the proximity sensor, or interfering with the touch screen when you try to use it. But whenever a ground is applied (a charger, or grounding the chassis via the kick stand to your body) the problem goes away.

    Not humid here. I can replicate this at home and and work.

    What about screen protectors? I'm trying to find some common ground here. It's almost Excel sheet worthy at this point... Excuse me, I meant google docs .

    I just found a micro fiber cloth in my wallet, I know, and can't replicate this. I'm at work and about to go to the bathroom so I can take my clothes off and test lol.

    Has anyone who didn't experience this been able to create this?

    This is normal...

    Setting your phone on a sock or something with a very high insulating effect will cause touchscreen glitches sometimes. This is a common type of quirk present in most capacitive touch screen phones and devices.

    It is due to grounding of the phone and how it affects its ability to sense the conductivity of the flesh of your finger tips. You might also find that certain chargers (particularly high current) will render the touchscreen to not work at all or even make it sense touches that do not exist (ask the droid milestone users!) This is not really a bug in the phone, just a manifestation of the technology in it under atypical usage conditions. If you touch the phone with your hand the problem goes away.

    I am having the same problem, but it happens anytime the unit is level (like on a desk) and I am not holding it, I can put the unit on ALL types of materials (i.e. paper pad, mouse pad, laminated desk, glass) and the top portion of the screen becomes unresponsive. I can't get notifications to work and the top 1/2" of the display is intermittent.

    Mine phone also seems to sufffer from this. Only top half of screen. I have the Body Gloves and screen protector.
