[Discussion] DHD - Crappy digitizer

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.

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)

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?
Sent from my Desire HD using XDA App

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.

Screen responding without touching it

Does anyone else have their screen respond without touching it?
I've noticed this in go sms. On the conversation list, the last one on the screen is sometimes pressed without me touching it. I will press back and it just goes back into it.
I recently noticed in web browsing too where the screen would refresh on its own. I clued in that the refresh button is on the bottom of the screen.
Seems like the bottom maybe 2 cm of the screen sometimes responds on its own.
Is there any app that I can see where the screen is being pressed?

Settings, Developer options, Show Touches
That will visually show you where any screen touches are occurring. The screen is a bit sensitive for me sometimes, but I haven't seen anything crazy yet.

Same here. Sometimes it happens to me. I would say one of 50 touches it'll react even without me pressing finger on a scren.

I definitely know what you're referring to, and it does seem to happen only on the bottom of the screen. Sometimes I'll trigger the screen if my finger is close but not touching it.

The thing that bothered me today is that i was trying to press a button in the top left corner and the bottom link kept being pressed so I have to hit back and I was trying to beat the bottom press but I couldnt lol
I dont think there was any moisture on that part of the screen either

Yep, but not on this phone yet...
I say not yet because it's happened to me on almost every one of my touch screen phones. It seems to happen to me when the air is dry and I bet it has to do with there being more static electricity around. On those days when you're shocking everything you touch, those are the days when my phones seem to act up. It happened on my G1, my vibrant, Droid1, Droidx, and two of my bionics. All of the problems went away although on my 1st bionic it was really bad and almost completely unusable. The next day it was back to normal. Maybe it's just gremlins.

answer:
it happens if/when you use a DIFFERENT charger for the phone. you should be using the charger that comes with the phone. If you use a different charger (from a G1 or from a razr or something), then the screen tends to mess up, even when off the charger.

Is yours also happening towards the bottom of the screen?

For those of you with this problem, try pulling the battery out for a minute or two and also try touching something metal if you can. You know to discharge any static built up. (Worth a shot right) When I had this problem on my Sensation everyone was reporting that it was the charger they were using. I don't know if that was correct because the problem went away even though I was still using two different chargers. One charger was for the GNEX (same as GS3) and the other was the HTC charger. I really think it has to do with static electricity build up. If you think about the way these digitizers work it really makes sense. It seems to happen to me during spring time when it's dry and windy.

That is a good theory, but why would the static shock only be hitting the bottom part of the screen?

i don't know why. but i'm sure it's the charger. this happened back in the G1 days when android first came out. i did so many "experiments" with different chargers to figure out what was causing the screen to be all glitched like this. found out it was the charger. same thing happened with my vibrant, and same thing happened with my sisters sgs2.

Screen ripple fix?

Yeah, I dont think an rma is going to fix this. Don't squeeze it so hard... fixed.
Mine does it as well, so not knockin ya but. It has yet to be an issue in actual real life use. Sure you can sit there and pinch the thing, but just stop, and you'll never notice it again.

I am very OCD about my devices. Honestly, as long as I know that nothing is wrong with it in that category, I will be fine

I noticed the ripple on two of the three N7's I tried. While I think it probably SHOULDN'T be happening (i.e., it represents an underlying design and/or manufacturing flaw), I don't think it will cause any issues. Like the screen lift, it's one of those things where it's technically a defect, but it's not likely to cause any performance or other issues.
If I hadn't had other problems with mine, I'd have put the best N7 in a case and forgotten all about those two issues.

What were your other problems

My first one had pretty good screen seperation all along the left side, and pretty bad lightbleed from the left side.
My new one has barely any lift (just a 1 inch section, about a third the way up on the left side), but has the lcd ripple.
The screen seperation isn't even noticeable unless you lay it flat and look across the glass and this one feels solid, the first one was spongy.
I can handle the ripple, because it only happens when im messing with it, trying to make it happen.

Tried it on mine. I am kind of shocked at how hard it had to press to get it to ripple. I am hoping get that the op has a worse case than I do because if not this is crazy. I would never pinch that hard I every day use.

Multiple bumps on chrome bezel and loose rubber edge

Hi
I was just wondering if I was the only one with several fairly noticeable bumps on the chrome bezel.
Also, I think my rubber edging is loose as it can easily be made to click loudly if pressed gently anywhere near the bottom. Also, when a cable is plugged into the port it moves a fair bit and the slowest and gentlest movement upward creates a loud click. I think it is the metal on the male part touching the female part but it sounds louder than it should be, sort of like static.
So, should I be worried enough to contact Google?

I have a few of those little bumps on my chrome bezel as well. My first N4 (now on my replacement due to signal issues) didn't have them. At first they bothered me, but the rest of my phone works fine so I'm happy. I don't want to replace it and get a phone with a problem that I can't live with.
As for the creaking/click sound. My first phone did it and my second one does it as well, though not as bad. I think on my first one I actually made it worse because when I realized it made that click sound. I would often recreate it by pressing on that same spot. Not sure why. Maybe I hoped it would fix itself and suddenly go away. I'm sure you could replace it, but you may get another phone with a worse defect. If the only thing wrong with your N4 is that click sound, I'd just enjoy the device as is. If at some point in the future something more severe takes place, then I'd look in to getting a replacement. Over all the years of using cell phone. I realized there's no perfect device and I'm OK with that.

That sounds exactly like my phone and what I do yo recreate the sound. I try not to so it but I do sometimes hoping it has gone since last time. Maybe I should send Google an email letting them know and if it gets worse they can't blame me.

I suppose you could try that. It couldn't hurt to call them and relay your experience.

The USB port clicking when plugged in, is caused by the port not correctly installed into the phones housing. I had the same issue and to fix it I opened and disassembled the phone and moved the port lower into the opening so the port stays in place. The noise is caused by the port clipping the edge of the opening in the housing.

Thanks it helps to know what is causing the problem but to be honest I'd rather see if it gets worse and if it does get Google to sort it out than inevitably break it if I try and take it into my own hands. It doesn't inflict functionality at the moment and I'm going to start using wireless charging soon.
I'm glad you managed to sort yours out though!

I have like two bumps on my top left corner. Do you have lines running down all corners? Is that possibly from molding?
Sent from my Nexus 4 using xda app-developers app

Hey guys, I've been searching for this problem.
I also got a bump on the top left of my phone, just right of the headphone jack. Tried to "push" it back with force, but it would not give.
Also, I got the clicky bottom, which is weird.
So, anyone knows how to fix these bumps?

Anybody else have a slightly curved back?

Does anyone else noticed the back of their Nexus 7 being ever so slightly curved? Not that this is something that would bother me, but when I place it on a table it is able to have just enough rock to it that swiping my finger with it or plugging a cable into it will pull the device in the direction of the tension.
(Moderators, I originally put this in Q&A, but since I realized it isn't so much a Q&A thread, I put it here in general. You can delete the Q&A one)
EDIT: Video comparison I just made - http://youtu.be/EhS7-KTwn4g

I believe it is designed that way so the speakers don't sit flat.

But it is down the vertical spine of the device, not the horizontal one. Plus the speaker grills are placed on the curve of the devices edge, so laying flat shouldn't be much of a problem anyway.

Not sure then. I just tried it with mine and I don't have that problem.

Best buy just refused to exchange it and wouldn't even try another device to see if it also did it, claiming it is a design choice (clearly she was on the ASUS/Google development team). Nor would they PM with the Staples coupon after the fact (but I can understand that one). She was just very rude and dismissive.

I just laid mine down on a marble counter. It sits flat. Only the edges are tapered for the speakers. Its pretty sturdy.

Yes! Somebody else notices. I was using my tablet in class today vertically and it kept turning horizontal. I noticed that the back isn't completely flat which is causing it to have movement when I lay it on a flat service.

Yeah, It might not be a huge "issue" (as the comment on my video says), but it is very annoying, especially considering I like to have the charger plugged in when I'm on it at times, and if there is any tension on the cord from where it is plugged in to where I am sitting, it will pull the tablet toward it.

I didn't really notice either until I had it plugged in and kept pulling away from me. Then I noticed it when I would swipe the screen. It really is annoying but I don't know how widespread the problem is and it is hard to gauge from the limited responses in this thread so far.

this really shows how far people are willing to go to find something to complain about..
slightly curved back that allows your device to spin freely when on a perfectly flat surface... really?
