Weird Touchscreen behavour - Video Doku.

Hi, I'm a big fan of the HD2 but in the last two weeks, since i own this device, i'm getting confused by some screen imput behavour that i will present you.
I want to figure out if this "screenbugs" i have to fight with every day, are normal or a hardwaredefect. To make you guys an imagine of what i mean, i uploaded some youtube videos for each bug.
1. The first one i call: The painting edge
This bug is only present if i not have installed the less sensitive CAB from this forum.
Explaination:
Many of you have notice that the glass of the screen doesn't fit exactly in the case of the device. The right bottom of the glass protrude a very little. Then i lightly press on this position, the screen notice a press on the right top...as you can see in notes on my youtube video:
Video 1: http://www.youtube.com/watch?v=c49x9vB4bzQ
------------------------------------------------------------------------
Beforce you say...my device doesn't having any of the following bugs, REMEMBER, This bugs are not present every second. Sometimes i can use the device for 30min without having some of this.
------------------------------------------------------------------------
2. The Electrocardiography
This bug, i think could be the reason for the following bugs.
Explaination: Trying to draw a straight line an you think you device will get a heart attack soon.
On the half of my second try you can see how the device suddenly works normal again.
Video: http://www.youtube.com/watch?v=t54m1dSLnV8
3. The shaking Screen
Explaination:
I have notice that some other guys have this bug too. You can see this on every scrollable screen, like opera, IE, zoomed pictures, the manila tab, startmenu...etc. etc.
Best seen on minute 0:54 in my video.
Video: http://www.youtube.com/watch?v=6hIE_wV4djs
4.The non pressed key
Explaination:
You are cofused about keyboard reaction while writing a text message? You type an "a" and getting a "t"? Than you have "the non pressed key" bug how i call it.
you have to watch on some key input where my finger is totally out of range. I don't mean the fault input next to the key i pressed...
Video: http://www.youtube.com/watch?v=_B1GiyMp_O4
----------------------------------------------------------------
There is a fifth bug i didn't get on video yet because it is very rarely.
I had have this bug only 5-6 times since i own this device, but it sucks realy hard.
I call it
5. The self-typing keyboard
Explaination:
Then i'm typing some text sometimes the keyboard begins to typing without having the finger one the touchscreen. it can be have a duration of 5-10 seconds or 20 letters/numbers.
It can also be watched, without keyboardaction. Then the screen scrolls wild in any direction without any finger on screen.

----------------------------------------------------------------
If someone can tell me if i can embed the youtube videos in this forum...

Go get a replacement, the screen is perfect. Although I admit it does not fit correctly but it is great. I only need the earpiece fix

please watch the videos before you comment anything...

...You're too much electrostatically charged...
...Or something of electrostatic is in the range of your device...
But it's like your touch panel is faulty. Get a replacement (warranty rules)

Have brought it back today...but couldn't get a replacement...no devices

tryed all your test and get no errors on screen, electro worked perfecly, keyboard keeps presing same key without leaving the range, and i cant notice any shaking effect.
So probably your screen is faulty , change your device as fast as you can matte

I have brought it already back, but it seems to be that others have all my listed bugs too. take a look at the poll results. On another forum a guy has tested the "painting edge" on 3 devices after he saw my video and all devices have this bug!!!!

Hey Guys,
I have the first 3 bugs on my HD2, too. But with BSB Tweaks 1.31 i solved the first 2 one by activating the option "Screen Sensitivity".

Hi,
If you look in the sticky thread here somewhere in the LEO section about tweaks and registry changes there is a topic on reducing the sensitivity of the screen.
I think what's happening here is the electric current in your fingers is playing havoc with the screen when your fingers are either close to or on the screen.
Let us know if this helps you.
WB

whow, that's a lot of problems for one device.
I have the "non pressed key issue" : (that's annoying as hell, typing a message is a heavy burden now) and the shakey screen. should i bring my handset back or try the tweaks... I didn't expect this from an 600€ handset

When i was made this video my finger was always with the same pressure on the touchscreen. It was not close...and not weak on screen...normal pressure. And you can see at the middle of my second try where i'm drawing lines in notes that the screen suddenly works normal.
I also wrote in my first thread, that this bug is not every second present...but then it's present its also the reason for some other input errors, like the "non pressed key" i think.

Quick question: How much pressure do you apply to the display (what is "normal"?)? Scince your display is reacting weird to pressure on the bottom right corner, any pressure might be linked to erroreous behavior. Do the shaking related errors remain when you don't press at allk?

to the OP: what ROM are you on ? have you tried 1.48 ?

I can recommende you to use screenprotector film and install cab for less sensitive.
But even without this all I had not this problem Looks like your sreen very sensitive for electrocharging and not have normal ground contact. This is way to warranty service.

lmao >.< sorry mate but get a replacement NOW!! I've never got these problems, everything works smooth and properly, sorry about that...

do u have a screen protector? i am wondering if the screen protector does anything bad to it...

You have the exact same problems I had when I first got my device, the main concern was the device having its own mind and making random key presses, even without you touching it or even being near it. I got my unit replaced and the new one works like a charm.

I noticed today that MY PERFECT SCREEN starting acting weird !!!! Its jittering !!! Damnnnn !!!!

I'm totally spooked by your video's!!!
I personally never experienced these bugs so I spend the last half our replicating your bugs.
The only thing I noticed was that Electrocardiography but I think you have your finger too flat on the screen (it has a too large surface area) because when I write on the screen as if my finger where a pencil (straight up instead of flat) the screen is working as it should!
I think you must have a faulty device. Perhaps try to flash it with 1.48 if you haven't done that already.

On iPhone with exactly the same finger it draws almost a precise straight line. This problem comes directly from HD2's screen, not from fingers, weather, humidity and so on.

Have to slow down when texting, what to do?

Hi there
Sorry if this is already debated. I searched but couldn't find an answer..
When I'm writing a text message using "phone keypad" and XT9 my HD2 can't really keep up with my writing-speed. It's not that I type VERY fast -but for example if I write two of the same letters in a row, the phone can't keep up and I have to slow my writing down. It's doing it in other cases also if I write pretty quick.
Is there a reg fix for this or is this a part of the sms-hotfixes that haven't been corrected yet?

did you give Swype a try?

I like to think that after using the Diamond for 18 months, because of it's small 'candy bar' shape I could touch-text fast using the keypad.
However I don't use the keypad on the HD2, I tend to use the keyboard, but with that said I haven't noticed any slowdown at all on the device I am only hindered by my clumsy finger placement.

Ok, thanks Can you even type double letters quick without it stuttering?

Ok, I found out that the slow response is only present when vibration feedback is on. So I turned it off. Maybe I'm a rare breed that likes to type with Keypad/XT9/Vibration - as I don't see people complain about this

you're not alone..
I have the same problem (vibration is already off) and it's very annoying

For me there is a clear difference when I turn vibration off, hmmm
Anyways I would like to have vibration ON, but is's unbareable to write on then..

@ OP. Not only is the delay in typing no the keypad, it also delays if you try to set a PIN code on the lock screen.
There is a HUGE lag as well. You should see for yourself.

Recommendations for a stylus please

could anyone share any experiences for a good working stylus for the hd2?
this phone is stupendous but alas i have to use it for work and the software we use requires very tiny touches and signature signing.
have tried the ones on e-bay (rubber topped pencil turned upside down)
which is crap...have now tried the htc and dagi ones with the tiny red dot and they are just not cutting it.
has anyone done any homemade experiments or come across a moe "pointy" stylus
toodle pip amigos

I got some, and they were crap...

Unfortunately you are all too correct!
With the glass screen!
Put a protector on it and they work!

I have been using the dagi long slim one and it works ok, I do have a screen protector on though so maybe this helps... makes selecting text and writing Chinese characters much easier (I use my hd2 to study/translate Chinese so being able to use a stylus to do this is pretty great)... its a bit fiddly to start with as you need to learn how to use it properly, but once you get used to it everything is ok...

Most of the styli are crap, I need something with more of a point, but that's probably not possible. Still waiting for some sort of battery powered pen that offers pin point precision, a guy can dream right...

i'll try to put a screen protector on as suggested and try...
my problem is it's no good mastering the dagi myself as i have to get customers signatures and most people simply can't use it...
it deffo needs something more pointy.
i'm sure i read somewhere on the forum about a guy who was filing something to a point till it stopped working???
i'm so frustrated as this is the only phone in 8 years that uses my works software flawlessly...except stylii

I have ordered the official htc stylus 400.
arrives in 2 weeks and i'll post comments.
read a review after ordering that it actually scratches the screen!
I guess i should have waited for the 400/2 version!
look on the bright side, will probably misplace it by the second day anyway

I've tried using my DS stylus but that doesnt work, seems like it was made for bigger objects to come in contact with the screen (ie fingers).

It`s not about the size of objects. HD2 has capacitive screen.
"A capacitive touchscreen panel consists of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO).[2][3] As the human body is also a conductor, touching the surface of the screen results in a distortion of the body's electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location can be passed to a computer running a software application which will calculate how the user's touch relates to the computer software."
Wikipedia

thanx for input guys..i least i know about capacitive screens now thanx to kregowski...although i sorta knew.
so if someone could come up with a small pointy thing that gives off some sort of electro staticy stuff...we in..
the search continues

Got the dagi (10 euro from Hong Kong). I am not amused... Touching the screen with the complete tip flat on the screen is annoying to get used to. Often only the side of the tip touches the screen.
When the tip is flat on the screen (which it should) it just does not feel OK. Not "delicate".
Which the screen responsiveness lowered and the tap-reaction time increased (which I did just to be able to get some decent fingertyping results) the dagi does not function adequate. I have to aim more accurate then with my fingers and have to press the dagi on the screen.
Putting the screensettings to default (which I did not try yet) reinstates all the drawbacks in the other functionalities.

Sensitivity of touch screen

Lo,
not sure if it's just me and coming from my Hero, but I do have issues at times with the screen getting to recognise my finger presses. This can be in games to apps; I generally find that a firm press works but surely this should be needed.
Can anyone else confirm whether they have the same or whether mines gone a bit dodgy?

mine responds verry good, i dont actually have to touch the screen, holding my finger above it also works (so yeah its damn sensitive)

same for me

Mine started to feel less sensitive and on web sites I find it had clicking on curtain parts of the page for example I click my ebay tab but have to give a few tries as it thinks I clicked the tabs either side

Yeah,,i'm the same when trying to select tabs on dolphin hd. It was a pain trying to play fruit ninja too.
Mine did seem super sensitive at first too and noticed like others that if you held your finger really close,b ut not touching, the screen still recognised the touch.
I hope then this isnt something that worsens overtime - I'll wait and see.
Thanks

I'm curious about this now because at first I also noticed it would respond if my finger was very close but still above the screen. I don't know if I've gotten used to that now or if it's actually changed. There has been two software updates so it's possible they tweaked a setting. Despite not noticing the hovering touch any more the screen is still far more responsive than my Milestone.

With the last 2 updates, they did change the screen sensitivity.
Could one of you undo the updates or hard reset, and see if it is sensitive again? That way, we know it's just software and tweakable.
I can't because I do not have my phone yet. Lol... (actually that isn't funny)..

My phone has had all the updates done and I find my screen sensitivity to sensitive. But then again I have come from a Touch Pro 2 where it wasn't the best anyway.

No problems here. Search for multitouch test on the market for some objective testing. (You can also see with this app that HTC solved the weird multitouch problem that previous devices had.)

From my testing, it seems to react better to a greater surface area contact; the tip of my finger barely triggers it, but if I use the full end of my finger it seems fine.
Bit odd and annoying

Mine's *too* sensitive.

I would call the HTC helpdesk and ask for a pick-up repairment or go back to the store and swap it for another one.

C'mon Samsung - need S-Pen calibration!

As a left-hander, the S-Pen SUCKS.
I've set the phone to left-handed, but that isn't the issue.
The phone expects the user to hold the pen at an angle away from the user, and that's where the screen registers.
However, many left handers hold their pens at an angle TOWARDS themselves, and the S-Pen is off by nearly HALF A CM!!

Tell me about it...
It's so irritating

are you sure you got it in left hand mode? i have mine set to my left hand and tried writing with my right. was off like you said (to the right). tried again with my left hand and it seemed fine.

I have it set to left handed.
When changing the settings to right-handed and using my right hand (I'm a little ambidextrous) it works fine. Nice and accurate. Mostly because with my right hand I hold the pen at a conventional angle.
However, many lefties don't hold their pens conventionally (habits picked up by the necessity of avoiding ring bindings, minimising smudging, etc). Look at how President Obama holds his pen:
http://www.post-gazette.com/pg/images/200901/20090126ho_lefthandedobama_330.jpg
See how the nib of the pen is angled TOWARDS him? The Note thinks it's angled away and puts down a line in totally the wrong place.
Even with my slightly less unconventional left-handed pen hold, it's WAY out (no matter whether the unit is set to left or right hand use, though left is slightly less awful).
How hard can it be for Samsung to provide a calibration app?
Right now, the Note is a phone unsuitable for a President!

Do you find any difference when you change the screen orientation then back again?

None at all, unfortunately.

I find that no matter what I do with the pen it always seems to write half a cm above where I have contact on the screen

SPen uses autocalibration feature, which unfortunately goes off after some time. Which is a bug by itself but not the point..
Everyone complaining about pen being way off try this:
set it to whatever your hand preference. Please phone on flat surface like a table and reboot phone. Do not shake or touch it too much. Open SNote and try to draw around grid lines, you will see that pen works perfectly with tip being exactly as expected.
However more you use pen more it will deviate off until reboot is needed. It happens especially fast if you are using it walking, upside down etc.

Interesting (though it didn't help in my case)
But it the calibration goes off after time, then there is even more reason to add a calibration facility.

I reckon that only happens when you're using landscape orientation and then you turn off autorotation without first returning to portrait orientation. Try turning autorotation on, setting it to portrait and then turn it off. That should fix it.

Thanks, but it really is nothing to do with orientation in my case.
It's ALL about the angle at which you hold the S-pen.
It expects the nib to be angled away from you, whereas I hold a pen with the nib angled towards me.
