Hi,
One iPhone fan boy suggested to compare my HD2 with his iPhone by simple test as described here:
http://labs.moto.com/diy-touchscreen-analysis/
What I saw on my screen looked less good than Motrola Droid. In some places there is splashes on the line (close to center of the screen).
Do you have straight lines on your HD2 devices ? Please let me know because I think that's explanation of troubles typing with built in keyboard, positioning is quite bad.
Thanks !
Tried it yesterday and I have straight lines.
Edge performance seems to be not so good on mine, more like the iPhone.
No problem here...
I have no problem with this test on my HD2 nice stright lines... anyway i am using fix for touchscreen sensitivity.
mine are nice straight lines as well.. seems like OP has unsteady hands!!
Straight lines here too. I tried that test as soon as i saw it on the web. The HD2 performs well.
I have exactly the same problem. Not with my first HD2 but the last one ! is it a hardware fault? HTC support is not able to help
That sensitivity (and straight lines) fix v3.3 will solve your problems! I installed it and its straight as an arrow... search the forum for it....
I've not installed anything...
I repeat. I did not have any problem with my old HD2 that had the earpiece broken. But I have it with my last HD2. I tested both. Could that be a faulty touch screen!?
No, certainly not. Maybe they're using touchscreens from different manufacturers.
What exactly is your problem? Cause what you see is in the first post is not a problem, a problem would be it the lines jumped several millimeters, but that's just a slight inaccuracy there (~1mm), nothing to worry about.
Wait for some more answers here, and I hope people will post screenshots, it might turn out that HTC uses two different touch panels.

My problem is that sometimes the screen is accurate but suddenly it makes weird jitters like this :

and specially this !
http://www.youtube.com/watch?v=N8MmIErLhag&feature=player_embedded
Ah OK, I see. That's something different, not the normal inaccuracy that the OP was talking about. In this case, yes, looks like a faulty device.
Have you tried if it goes away when you apply the tweaks here: http://forum.xda-developers.com/showthread.php?t=604831&highlight=touchscreen
I haven't tried sensitivity fix myself, but I noticed that by default my device can't handle slow motion of finger. It starts jumping around as it was presented on you tube video as well.
i do have really straight and continous lines here too
Yes, I saw that and the first thing I thought of was the fact that I've yet to try an HD2 with a usable keyboard.
It would be nice if people could try this test without the sensitivity tweaks and see what kind of lines they get and also let us know if their keyboard is okay or not.
It would also bee good to know if the sensitivity tweaks affect the outcome of this test.

Look at my screenshot in the second post. I've not done any sensitivity tweaks.
And my keyboard is perfectly fine.
Actually, th screenshot in the first post doesn't look bad either. Definitely not as bad as the Moto Droid, more like the HTC Droid Eris, and that's fine.
The only thing that's not fine is what you see in that youtube video. But that's another story, there's definitely something wrong with the device you see there.
Here's my screenshot again. As you can see, perfectly straight lines without any tweaks.
mine seems to be quite good, but I've done other experiment. breathe on the glass in Your window and draw same pattern. do it slowly... wth?? I have a faulty doubleglazed window... imho this test is not that relevant, as sometimes when sliding finger slowly it shakes slightly... or maybe it's just me??
Here are two more. Looks perfectly fine, IMO.

Thanks. This is the kind of information I was hoping for.
I'm really just wondering if people with poor line results are those with unusable keyboards. I remember there have been a few threads here about the keyboard and some people have no issue at all while others find their keyboards unusable.
What program are you using to draw the lines fella's?
Has anyone else experienced their cursor randomly moving around while trying to type or pages scrolling while they're trying to read? My G2 has been doing this fairly frequently and I can send it back but I'm somewhat afraid to since mine does not have the hinge issue and (so far) has pretty damn good battery life. I don't want to just swap one problem for two more
It happened to me once, but I have yet to see it happen again. Strange though.

Mine is rediculous. Can hardly type. I also don't have the hinge problem, but the trackpad is all over the place.

You have the Desire Z?
Mine does the same thing with the cursor. Makes it very difficult to type a lot of the time. The only thing I can think of is maybe it's a lighting condition... maybe light reflects on the trackpad a certain way that makes it think your finger has moved over it.
I hope there's a way to fix it!
Im curious, are you folks charging when youre having these issues? i had the problem temporarily when i first got the phone so i unplugged the usb cable and havent had it since.
no mystery here guys. it's changing light conditions that are affecting the optical pad. it's the same notion as an optical mouse, if the light doesn't reflect back right it can go all over the place. try finding someplace with a strong overhead light and angling the g2 back and forth and you'll see it activate the pad. that's how it works, light not touch.
Had the same problem, only when charging tho.

I think you are correct...the desk at work has spot where light can come through...when I have my phone laying flat the screen starts to go crazy!!, I was like wtf. It ONLY does it in this spot,no where else...I guess that explains everything

Yes, I'm definitely having this issue. I started a thread a while ago about it. I took a video of it happening, too.
http://forum.xda-developers.com/showthread.php?t=799435
I have track lighting in my apartment, and that's what I think is triggering it. Mine's not as bad as the rest of yours seem to be. It very rarely "goes all over the place" for me. It just highlights random buttons once in a while. I can see how if it activates during typing that it would be a huge pain in the ass.
Stupid optical trackpad... was was wrong with a track ball? I never had a problem with my G1's trackball. Doesn't HTC test these things?
Yup, that explains it. That was my suspicion. Especially since when using Swype (where my hand covers light going to the trackpad) it never does it. It's never been while charging, though - not specifically, at least.
Try holding it towards a light and wave it around. You'll see the cursor jump around. Makes sense. Kind of annoying, but at least it's not a defect.

I actually had to stop using swype because it would happen EVERY time I tried to write in portrait mode
Strange, but it could just be the difference of how we hold our hands or something to that effect. I think the lighting thing does explain it, though.

That was my thought as well, T-Mobile should include a "how to hold" guide in the box
This happens to me whenever I try to use the phone when I'm sitting on the couch with my back to the window. Only place it happens.
Called T-Mobile a few days ago about this and the hinge issue and they immediately issued me a replacement. Probably won't be any better but worth a try right? And if it keeps giving me problems then I'll keep exchanging it until the Nexus Two comes out lol
so... ya... my phone's orientation's not working right now.
so when i use navi, it's still in port. mode rather than land. mode
i have rooted dx 2.2 and it's just not working since this monday.
somebody help me out please!
That's funny you mention that. I noticed that my X is VERY sensitive and will flip to landscape if I slightly move.
Check to see that your settings are right.
settings>display>auto-rotate screen. Check this and you'll rotate, unless your phone is broken.

it's funny YOU mention that because I was debating asking xda if anyone knew a way to fix it from being so sensitive or possibly set it to only rotate on specific apps.

I can't confirm this works. I've done it with my phone and I can't say there is a difference but mine don't flips to landscape that easy but I did notice since the 2.2 OTA update it does change much easier than before. Anyway try to recalibrate the compass and see if that doesn't help your issue. Settings/location & Security

First off, I'm not a hater.
I'm a previous HD2 user and in no way an apple fanboy.
However, I cannot fail to notice how increadibly bad our touch experience is with our dhd's. For instance, when you move your finger sideways, you'll notice how choppy it is.
Also, for example when playing Gun Bros, you'll notice that you won't be able to aim properly. Also there, it is choppy. Instead of giving all 360° you'll find segments where it just jumps over, if you understand what I mean.
I tried playing it on my friends iPhone 4, and it worked perfectly there. Very accurate.
I guess I just wanted to write my anger off and see if anyone agrees with me that HTC could have done a better job on the touch. I suppose samsung has a better touch with their 60 hz (or is it 69 hz) digitizer?
I have no issues at all with digitizer, what would say is that gun bros is still in beta stage.
I play plenty of games and not once come across any issues.
Yeah I've noticed that too when I was drawing stuff on it, when moving finger diagonally in a straight line it creates like a wavy line. Pretty disappointing but oh well, you can never have a perfect device...
I'm still happy I bought it though, much better then my last phone.
EDIT: Here's a pic, I tried my best to make straight lines as slowly as possible.
I find the touch screen perfect with no glitches or jumps in any game or app
Could be the game or could be an issue with your rom and the game
Do you have it overclocked and without general bugs? Those could be causing it
Or a power hungry app in the background making the game seem to jump
Another thought is a screen protector, when I put mine on it seemed to be alot less responsive

It's definately not an issue with the game, as I see this everywhere. It is a matter of the digitizer.
Also I am running it stock right now.
To those that say their screen is working perfectly, try flipping through the home screens very slowly from left to right or the other way around, with your finger on the screen all the time, and let me know if it follows the finger perfectly or if it's a bit choppy, as compared to when you go up and down in the app drawer for instance. You'll see about 9-10 "chops". This, I've reproduced on 3 different DHDs.
i'm using a -android Revolution HD and have no problems with the screen, i was trying to do dose things with finger and the window is yust there where i first put my finger on, so i don't see the problem here.
One of the kolegs have a iphone4 and we didn't notice a diference when using mine or his phone...
sorry for bad einglish

That is exactly what im talking about. Vertically it works fine but horizontally it is choppy big time! hence you cannot get a straight diagonal.

Agree completely. Very poor from HTC. Again.
I'll probably be shot down in flames by the HTC apologists around here...
Sent from my Desire HD using XDA App
There no reason to get flamed, we're merely stating the truth.
Surely, the dhd is a great device, but we shouldn't ignore the fact that even HD2 was smoother horizontally. The fact that a high end device cannot draw diagonals across the screen is simply crazy, seeing as it was possible with previous devices, and I cannot help to feel a bit ripped off from htc.
But before concluding too much, is there anyone that actually cannot reproduce this problem? If so, please post a picture where you can draw a diagonal (of course by moving your finger in a slow enough motion)

No problems with the touch screen here, I do a lot of gaming and never run into a single issue.

Please, as I said, try to reproduce drawing a diagonal before you say you don't have any problem. Or you'll just be spamming this thread.

I tried to do this with a drawing app and I can make "straight" diagonal lines when using a swipe action. I can also recreate the sample posted by drawing the line slowly.
What this means for the digitizer, I will leave for others to pursue.
Cheers from my DHD.

Yep, when drawing diagonally in a fast sweep motion the line is drawn correctly and when drawing slowly it becomes wavy.
I'm also interested if there's anyone not having this issue.
for me, fast would be straight and slow would be wavy...
It could be bad software. I read the LauncherPro thread here on XDA, and people are experiencing this choppy behavior on their Nexus S' and so on using LP.
Bad Sense coding? Might be. Can people with custom ROMs post their results?

I took that picture on LeeDroid 1.5.1 but that being said, it was the same result when I was on stock as I tested it out before.
I wonder if it's the same with a CM7 Gingerbread ROM.

Id say that when moving fast you exceed the 50 hz limit and not all the "reading points" are used.
But it might be software related, could anyone with CM7 try to reproduce this?

It is all about software, the digitizer itself is great. I have a touchscreen pen, and I can draw bullet straight lines with it, no matter how fast or slow.
Then when I put my thumb on the screen and draw, the result is wavy. Our devices just need better handling for large touch areas.

Hmm! He's right you know. If I press VERY lightly (so only the very tip of my finger is on the screen) I get a pretty straight diagonal - but if I press down with the pad of my thumb, it's got the steps in it.
Seems like it's having issues determining which point is actually the centre of the capacitance.
I discovered a weird little thing with my touchscreen a while back and I was wondering if anyone can replicate this. I would like to know if I'm alone on this issue or if anyone else can replicate this.
The issue is that when my Atrix is sitting on a FLAT surface (i.e. table, desk), the touchscreen works perfectly.
When the Atrix is laying on a SOFT surface (couch, bed, pillow), the screen becomes unresponsive.
If anyone could download a multitouch app (search "multitouch" on Market - Multitouch Tester is a nice one) and try this out, I would really appreciate it.
Thanks!!
O.O strange man, are you using the original ROM?
lol something similliar happens to me, i think its just that it looses proper contact when its on a soft surface...

Yeah I noticed this a few weeks back when i was lying in the bed trying to browse the internet. Every time i attempted a one finger scroll, it kept registering it as a two finger pinch-to-zoom.
This happens to me on retail stock 1.26, 1.57, and 1.83

Now I know that this is not a "feature" of the Atrix.
A similar feature that does happen across all of the Atrix devices is when you hold your finger for 10+ seconds on the same spot on the screen, the touch will stop registering and the screen will malfunction until the finger is lifted off the screen.
Before 83, this would happen to me all of the time, but now on 83, my Atrix is superduper responsive on all surfaces

This becomes a particular problem for me while I'm using touchscreen controls in various emulators, although it doesn't seem to happen when I'm using a virtual joystick with only one finger on the screen at a time, i.e. while playing Dodge This in PewPew. It's worst in racing games where I'm holding down the accelerator button almost constantly while moving the virtual joystick at the same time. I'm using the 2.3.4 HKTW ROM; is this a physical problem with the touchscreen, or might it be resolved in a future software/firmware update?

From what I've read on the Motorola Forums, it's supposed to be a "feature" that helps users.
It SOMEWHAT makes sense, but the real problem here is that there should be a feature where the user can turn this off.
I don't believe it will be changed with any official software/firmware updates from Motorola. We are stuck
My phone did the same thing on soft surfaces. Now my touchscreen went bad and I have to get a replacement.

Hopefully, if mine does go bad, it will be before warranty expires.
Sounds like an electrical grounding problem. The EVO 4G suffered this same issue.
