Edges of screen unresponsive?

Anyone else notice that the edges of the screen on the cmda diamond, cdma pro, and the HD seem to be MUCH less responsive than the screens of previous devices?
I "miss" the exit and start menu buttons pretty often and its pretty annoying lol.
Also the notification/title bar area plus other buttons along the bottom and side.
The rest of the screen is more responsive certainly than say the vogue, mogul, diamond or tp. But its the edges of this and the last 2 mentioned devices that get me..

Well I also feel it's less responsive, but not so much actually. Besides this is caused by the technology of the touch screen.

You mean the edges or the whole thing? The main part I feel is more responsive...

Edge responisiveness depends highly on screen calibration. Try to recalibrate screen more precisely, I think situation should improve ...

Hey thanks a lot. Thought the same thing myself.
Re-calibrated as accurately as I possibly could.
Still no go. I would really like someone else to try this. Take out your stylus even and press in the very corner of the X-button...you get nothing.
Sort of fix: I found that if you hold your press just a little longer it registers (much better) though I'm not quite convinced that it's still normal nor complete.

I don't see any problem in pressing X-button on my Touch HD. I had similar problem like yours using right vertical scrollbar and recalibration helped, so I though it might help you too, but unfortunately it seem this ain't the same problem

Hmm...I wonder if I should try to get it replaced under warranty.
I would want to, but I have noticed the same problem in a sprint diamond in the store, a sprint touch pro in a store, and a friends sprint touch pro.
What do you (guys) think? Replacement? It could get really annoying...not being able to close out of things. Right now since its new and awesome and stuff I'm kind of trying to ignore it or whatever but...hmm idk.

The fact that the screen is less responsive near the edges is caused by an inherent technical limitation of resistive screens. The screen has no real bezel, and thus, the screen is attached to the body frame right where it ends: at the absolute edges of the screen Where it is attached, it cannot move. A little further away from the edge it can move (eg be pressed down) but this requires more force since you need to bend the screen much closer to the fixed edges than when you would press the center of the screen, which bends the easiest.
Don't know if this makes sense, but it's like a window... Hitting it in the centre will break it much easier than when hitting it close to the edges, since the glass bends much further/easier at the center, so the same force will have more effect.
Anyway, resistive screens have this problems, capacitive screens do not, obviously, since they do not rely on pressure.
If hitting the OK/Close button is a problem for you, just use the hardware button below the screen, the one with the arrow on it. It does exactly the same thing I believe. With 'I believe' I mean I assigned OK/close to that button using AEButtonPlus, which should be the default behavior for pressing it once. I find this to be much more convenient than trying to hit that tiny X/OK button.

Hey thanks for your informative opinion.
This theory seems to fit, except it doesn't quite explain nor fit with these 2 things:
1. I can apply a pretty decent amount of pressure in the corner with no results whatsoever. But I can get full results if I apply less pressure for about .5-1 second rather than just tapping.
2. I have never seen any evidence of this on any other resistive touch devices (vogue, titan).
Why in the world do these resistive touch screens have to suck so bad anyway? The HD is the best I've seen lately, but does HTC just suck at it, or is it everyone (haven't owned a non-htc ts device for a yr or so, and that was a treo where I didn't really notice sensitivity).
My dad has a 3+ yr old Dell Axim X5 and that screen is AMAZINGLY sensitive. Responds to stylus and is too old to be capacitive. But it is literally 100% as responsive / sensitive as the screen of the iPhone. When I used it I couldn't believe it. You had to be VERY delicate and careful and trying hard to touch that screen and not have it know.

Am i the only one with this touch screen problem ?

Sometimes the touch screen is WAY off and only restart is fixing it. Noticed this 2 times already.....

I've noticed this too. I was using the browser, and my screen presses were registering as all sorts of random things (like pressing the middle of the screen would press the zoom button). Restarting the browser seemed to fix it.

Add it to the nexus one issue list.

that's from a lack of multitouch. your hand is probably just barely touching the lower corner of the glass. when you press again in the middle, it registers on the softkeys. it is one of the things I *HATE* about this phone. I always seem to be touching the screen on the very edge. you almost cant use it with just one hand.

I find that I do that with my HTC Magic sometimes as well, the 'webbing' between my thumb and index finger sometimes touches the corner of the screen and brings up the 'app menu' in my left hand, or the 'add widget' menu in my right hand (sense ui). Just another general thing about touch screens and their placement

the four touch buttons arent that accurate. didnt have this problem on the droid. i rarely miss it there but on the nexus is becoming 50/50 chance of it not registering.

Lol how are you guys holding the phone, i always use it one handed and havent expirienced this, i guess everyones different.

This not necessarily a problem with this phone in particular. It is a phenonema that happens on all capacitive touch screens (that do not have multitouch). I work with them all the time (much larger scale) and the slightest touch on a border results in what appear to be calibration issues.
Multi touch takes into account for this, non multitouch does not.

This has happened to me also. Same exact thing, in the browser, the touch was way off, really way off. I was pressing the middle and the zoom button pressed. It was on the table so I know my other hand didn't touch it. It was also vibrating sometimes when I pressed the middle of it. Restarting seems to have fixed it for now.

happened to me in SMS and browser and the only fix was restart the phone.....so its not me accidentally touching the screen in another point.
ps. its so bad that i couldnt even use touch screen to power off the phone. i had to use track ball. (now i know why its there )

I've had this problem as well as other with touch screen. Sometimes I will hit an icon on the main screen and it will jump screens. When I'm in the menu's i hit one of the options and it goes to the one underneath it. I'm CLEARLY hitting the option I want and not the one below so it is infact a hardware problem in my case. I will be in the browser and hit a button and it will exit out of the browser, very annoying! Mine is unlocked but I wrote HTC so lets see what they say.

its a known prob with this phone, ppl are complaining all over Google forum, its very annoying, when it happens it doesn't just happen in the browser, also in text message n home screen ect...

Webbed fingers are gross.

I have now experienced this definitively once. It happened while using the dolphin browser. I wiped the screen off, set it on a table, poked with only one finger, and could not for the life of me get the software keyboard to click on the correct button. Just wouldn't happen. Had to restart the phone to fix it. But it's only happened once since I got the thing on launch day.

^ same thing for me. Does the OTA fix this, I have not received it yet. Wish I saw this before I created a thread, sorry.

i dunno, but touches (especially multitouch) seems ALOT more responsive and accurate than before i did the new update... i used dolphin prior and pinch zooming seemed jittery and like the phone didnt want me to do it... now everything seems smooth as butter!
obviously this is only short term though, but hopefully this fix will also address some of the calibration issues (that i also experienced) that the N1 has been known to have...

screen calibration

is there a way to calibrate the screen? sometimes feel the click is not accurate.

no, these screens should not need calibration anyway. If you're talking about the click being off a little on the home screen I have that as well, but it seems to be limited to the Live Wallpapers. If its off by alot you should send it back for replacement.

when i click the dot, sometime the search box pop up. the dot is above the search botton

dot? what dot?

I think he means the dots at the bottom of the screen to move from one screen to another on the Home launcher. The dot(s) is/are right above the search button on the bottom right of the screen.

oh, yeah that does not sound normal. try restarting and if the issue persists you mgiht want to consider sending it in.

I've noticed sometimes random touch events happen, I'll touch something, and something else gets activated more than half the screen away.

are you sure you aren't touching another part of the screen?
Sometimes the palm of my hand touches the bottom left of the screen and that will cause random touch events.

You need to touch slightly above the dot. Otherwise your finger is very close to the google search soft key.

I know for fact that sometimes I DO touch other parts of the screen like with my palm, etc by accident. however there have been cases where this wasn't happening and I still have miss touch events.
Example. I was holding my phone with my fingers in landscape with my left hand, and using only the pointer finger of my right hand to touch something in the middle top of the screen, at which point the phone pulse vibrated and the quick search screen popped up.
I posted to the google link outlining the different events that I have noticed. Multitouch would fix point averaging between somewhere you're accidentally touching and where you intended to touch. This however isn't the only thing going on, as I do believe there is some random strangeness occurring. I never had any such issues with my G1.

it happens to me,too, i thought it is caused by my palm touched the edge of the screen when i clicked using finger, but it is not. when i restart the phone, it,s gone.

yes. that's the dot.
I read from another reviewer, he said the sensor of the soft key is located a little above the icon for the key. this may cause the problem.

This messes up pretty much everyone I hand my phone to look at/play with. Its fine if you're aware, but it does show a sign of less refinement in a device that would have been nearly 100% free of hardware design flaws.

I feel the same way, especially with the soft-buttons and the "p" key in portrait mode. Last night after walking a bit outside my key-presses were atleast an inch off.....I attributed that to my fingers being a little staticky.
Othertimes my fingers just never work on the screen for a few seconds, rubbing my fingers together fixes this problem.
Something to do with http://en.wikipedia.org/wiki/Capacitive_sensing I guess

I find that sometimes my fingers wrap around the phone and just touch the front edge of the screen while holding it, causing random key presses. I guess I'm still used to holding the wider and less sensitive Touch HD.

[Q] Back and Search keys unresponsive

Is anyone else having issues with the back & search keys at the bottom being unresponsive? We have 2x epics and both appear to have this issue.

back button working good here. havent used the search button more than 3 times since i got the phone.

This appears to be a fairly common issue. A lot of people are saying they have issues with different buttons. My home button is the least responsive.

I have to mash the "button" area considerably to get a response - perhaps it waits for a certain amount of capacitive load/change before activating. That would help reduce unwanted taps when swiping across the screen - the Evo was wonderfully sensitive, but an overzealous scroll often had the unintentional side-effect of bringing you back home or backing you out. Also, the Evo, for me, constantly brought up the search dialog if the edge of my hand came too close. So, I suppose it's a tradeoff.

This isn't true. My Epic capacitive buttons respond to a very light tap and also a full on *press*.
sounds like non-functioning buttons to me.

You might have a bad sensor on your buttons.
I did have to get used to them. The Evo's were very sensitive, in fact in landscape I'd often accidentally brush one and it was a little annoying.
The epic does seem to need just a half second or so longer for the tap to be recognized.

thats more annoying. It makes the phone feel laggy, atleast to me it does. All the my buttons require 2-5 touches before they register

I'm not getting that at all. You might want to bring it back and swap it. It takes slightly longer than the evo to register but it feels "about right" to me. When I want to hit it, I have no problem hitting it.

I went to the Sprint store yesterday. The guy told me the early phones had this issue. I asked to try out the one he was giving me. He said, he'll be back and need to take it to the tech for setup and "an update"?...huh, already?
Anyways, he came back and I tried out ALL the buttons. A VERY lite tap and it responds...all of them...

I had a poll going before, and it looked like the issue was relatively wide spread... Apparently though, some phones do not have this problem. If you get this, swap out your phone, it is likely defective.
BTW, the poll is at
http://forum.xda-developers.com/showthread.php?t=772063

I think part of the issue is that the buttons' sensitivity region is slightly below the button icons. If you tap above the buttons, they dont respond. Tap slightly below them, however, and they should respond every time... Unfortunately, this makes most cases for the epic 4g pretty terrible since you cant really press below the menu and search keys... Of course I could be wrong.

A question for Omnia 7 owners about the capacative buttons

I was curious whether the buttons are easy to trigger by accident.
On my Nexus S and the Focus, there is a subtle upward curve at the bottom of the phone. This small lip seems to prevent a lot of accidental presses of the capacitive buttons.
In my experiences with a completely flat face phone (the HD7), accidentally pressing the capqcitive buttons was extremely common and annoying. I like the looks of the Omnia 7 more than the Focus, but if it leads to similar problems as the HD7 (always pressing the buttons by accident) then I'd rather go with the focus.

For me that's one of the most annoying things about the phone. I hit the search button all the time.. But some say there will be a firmware update to fix that.

That's exactly what used to happen to me with my HD7. When I held the phone part of my thumb would be on the bezel and it would hit the search button. Also, when I held the phone in landscape my finger would also hit it.
With the Nexus S I don't run into this problem because the bottom is curved a bit. I've also played with the Focus a bit and it seems to have this slight curve at the bottom as well.

yup same thing here, this is when I spend time try to browse through apps and use my phone when it was still new. now i got the hang of it, and i dont really fiddle it as much as before now, just a basic need. and i got what a really wanted, fast and responsive phone.
